Abstract
Smoking cessation medications have the potential to affect the functioning of the nervous system, leading to sleep disturbances. Our study aimed to compare the sleep-related side effects (such as insomnia, abnormal dreams, nightmares, and somnolence) induced by different smoking cessation medications in non-psychiatric smokers. We conducted a thorough search of five electronic databases (Cochrane, EMBASE, PubMed, PsycInfo, and Web of Science) for randomized controlled trials. This study was registered with the PROSPERO (registration number CRD42022347976). A total of 79 full-text articles, encompassing 36,731 participants, were included in our analysis. Individuals using bupropion, bupropion in combination with a nicotinic acetylcholine receptor agonist (NRA), and bupropion in conjunction with nicotine replacement therapy (NRT) exhibited a higher likelihood of experiencing insomnia compared to those using NRT alone. Bupropion plus NRA had the highest ranking on the surface under the cumulative ranking curve (SUCRA) for insomnia risk, while placebo had the lowest ranking. Additionally, NRA plus NRT ranked first for abnormal dream outcomes, NRA alone for nightmares, and nortriptyline for somnolence, based on the SUCRA results. Healthcare providers should exercise caution when prescribing smoking cessation drugs, particularly in consideration of their potential sleep-related side effects.

Abstract
INTRODUCTION Behavioral and pharmacological smoking cessation treatments are hypothesized to increase patients' reward learning to reduce craving. Identifying changes in reward learning processes that support effective tobacco-dependence interventions among smokers who experience depression may guide patients toward efficient treatment strategies. The objective was to investigate the extent to which adult daily cigarette smokers with current or past major depressive disorder (MDD) learned to seek reward during 12 weeks of treatment combining behavioral activation and varenicline. We hypothesized that a decline in reward learning would be attenuated (least to most) in the following order: (1) behavioral activation integrated with ST (BASC) + varenicline, (2) BASC + placebo, (3) standard behavioral cessation treatment (ST) + varenicline, (4) ST + placebo. METHODS We ran a phase IV, placebo-controlled, randomized clinical trial with 300 participants receiving 12 weeks of one of four conditions across two urban medical centers. Depressive symptoms were measured using the Beck Depression Inventory-II (BDI). Reward learning was ascertained at weeks 1, 7, and 14 using the Probabilistic Reward Task (PRT), a laboratory task that uses an asymmetric reinforcement schedule to assess (a) learning to seek reward (response bias), (b) differentiate between stimuli, and (c) time to react to cues. RESULTS There was a significant interaction of BDI group × PRT response bias. Response bias declined from weeks 7 to 14 among participants with high baseline depression symptoms. The other two BDI groups showed no change in response bias. CONCLUSIONS Controlling for baseline depression, participants showed a decrease in response bias from weeks 1 to 14, and from weeks 7 to 14. Treatment condition and abstinence status were unassociated with change in reward learning. IMPLICATIONS Smokers who report greater depression severity show a decline in reward learning despite their participation in smoking cessation treatments, suggesting that depressed populations pose unique challenges with standard smoking cessation approaches.

Abstract
INTRODUCTION Blinding participants to randomization is a cornerstone of science. However, participant beliefs about their allocation can influence outcomes. We examined blind integrity, the association between trial arm belief and cessation, and potential mechanisms linking treatment arm and treatment arm belief among people with major depressive disorder (MDD) who smoke receiving varenicline in a placebo-controlled trial. AIMS AND METHODS 175 participants were asked at the end of treatment (EOT) if they thought they received placebo, varenicline, or were not sure. We assessed the relationship between treatment arm belief and actual treatment allocation, examined the association between treatment arm belief and EOT cessation, and evaluated changes in craving, withdrawal, side effects, depression symptoms, and smoking reward as mediators through which treatment arm was believed. RESULTS Treatment arm belief was significantly associated with actual arm assignment (χ2(2) = 13.0, p = .002). Participants in the varenicline arm were >3 times as likely to believe they were taking varenicline, versus "not sure" (RR = 3.05 [1.41-6.60], p = .005). Participants in the placebo arm were just as likely to believe they were taking placebo versus "not sure" (χ2[2] = 0.75, p = .69). Controlling for treatment arm, belief that one received varenicline was significantly associated with an increase in cessation rate (OR = 5.91 [2.06-16.92], p = .001). Change in the rewarding experience of smoking may mediate participant ability to discern getting varenicline (B = 0.077 [0.002-0.192], p < .05). CONCLUSIONS Participants receiving varenicline can discern that they received varenicline and this belief is associated with higher cessation rates. Research is needed to continue to examine how participants correctly identify their allocation to varenicline. TRIAL REGISTRATION Data come from the trial NCT02378714. IMPLICATIONS The present study adds to the sparse literature on blind integrity, particularly in the field of tobacco cessation. Randomized clinical trial participants can discern their assignment to varenicline, and believing that one received varenicline was associated with significantly higher cessation rates. Identifying treatment arm allocation may be associated with changes in the rewarding aspects of smoking that have been well documented with varenicline use. Masking allocation to varenicline is challenging. The effects of this medication in clinical trials may represent both pharmacological effects and participants' abilities to recognize that they are receiving the medication.

Abstract
BACKGROUND AND AIMS Smoking is considered the main cause of preventable death world-wide. This study aimed to review the efficacy and safety of cytisine for smoking cessation. METHODS This review included an exhaustive search of databases to identify randomized controlled trials (RCTs) in health centers of any level with smokers of any age or gender investigating the effects of cytisine at standard dosage versus placebo, varenicline or nicotine replacement therapy (NRT). RESULTS We identified 12 RCTs. Eight RCTs compared cytisine with placebo at the standard dose covering 5922 patients, 2996 of whom took cytisine, delivering a risk ratio (RR) of 2.25 [95% confidence interval (CI) = 1.42-3.56; I2 = 88%; moderate-quality evidence]. The greater intensity of behavioral therapy was associated directly with the efficacy findings (moderate-quality evidence). The confirmed efficacy of cytisine was not evidenced in trials conducted in low- and middle-income countries. We estimate a number needed to treat (NNT) of 11. Two trials compared the efficacy of cytisine versus NRT, and the combination of both studies yields modest results in favor of cytisine. Three trials compared cytisine with varenicline, without a clear benefit for cytisine. Meta-analyses of all non-serious adverse events in the cytisine group versus placebo groups yielded a RR of 1.24 (95% CI = 1.11-1.39; participants = 5895; studies = 8; I2 = 0%; high-quality evidence). CONCLUSIONS Cytisine increases the chances of successful smoking cessation by more than twofold compared with placebo and has a benign safety profile, with no evidence of serious safety concerns. Limited evidence suggests that cytisine may be more effective than nicotine replacement therapy, with modest cessation rates.

Abstract
SIGNIFICANCE Little is known about the mechanisms by which medication adherence promotes smoking cessation among adults with MDD. We tested the hypothesis that early adherence promotes abstinence by increasing behavioral treatment (BT) utilization. METHODS Data for this post-hoc analysis were from a randomized trial of 149 adults with current or past MDD treated with BT and either varenicline (n = 81) or placebo (n = 68). Arms were matched on medication regimen. Early medication adherence was measured by the number of days in which medication was taken at the prescribed dose during the first six of 12 weeks of pharmacological treatment (weeks 2-7). BT consisted of eight 45-minute sessions (weeks 1-12). Bioverified abstinence was assessed at end-of-treatment (week 14). A regression-based approach was used to test whether the effect of early medication adherence on abstinence was mediated by BT utilization. RESULTS Among 141 participants who initiated the medication regimen, BT utilization mediated the effect of early medication adherence on abstinencea) an interquartile increase in early medication days from 20 to 42 predicted a 4.2 times increase in abstinence (Total Risk Ratio (RR) = 4.24, 95% CI = 2.32-13.37; p <.001); b) increases in BT sessions predicted by such an increase in early medication days were associated with a 2.7 times increase in abstinence (Indirect RR = 2.73, 95% CI = 1.54-7.58; p <.001); and c) early medication adherence effects on abstinence were attenuated, controlling for BT (Direct RR = 1.55, 95% CI = 0.83-4.23, p =.17). CONCLUSIONS The effect of early medication adherence on abstinence in individuals with current or past MDD is mediated by intensive BT utilization.

Abstract
BACKGROUND People with HIV/AIDS (PWH) smoke at nearly three times the rate of the general population. Interventions to promote sustained quitting among PWH are urgently needed. METHODS Our study used a randomized factorial design to evaluate the effects of varenicline, compared with placebo, and behavioral cessation therapy, positively smoke free (PSF), compared with standard of care (SOC) among PWH who smoke. The study was designed with power to detect a small effect (Cohen's h of 0.28-0.36) with 240 participants. The primary outcome was the 7-day point prevalence abstinence (PPA) confirmed by exhaled carbon monoxide (ECO) less than 10 ppm for both main effects at 36 weeks. The study was conducted from June 2016 to November 2020. During the study's last year, recruitment was halted because of COVID-19. RESULTS The study randomized 184 participants with power to detect a medium effect (Cohen's h of 0.41). Participants were mostly African American (89.7%), men (62.8%) who smoked mentholated cigarettes (96.7%). Nearly all received antiretroviral medication (96.2%). Quit rates for the entire sample were 7.5% at 36 weeks. Compared with those who received placebo, neither those who received varenicline [36 weeks; OR (95% CI), 1.31 (0.33-5.22), P = 0.70] nor PSF [36 weeks; OR (95% CI), 0.26 (0.03-2.44), P = 0.24) were more likely to quit smoking. CONCLUSION Among an urban living, primarily African American sample of PWH who smoke neither varenicline nor PSF was found to be efficacious at 36 weeks. Our study was not powered to detect small effects sizes. Larger trials are needed to establish tobacco treatment standards for PWH who smoke.

Abstract
Achieving abstinence from alcohol, tobacco, or both may improve mental health, but is understudied in people with HIV (PWH). The St PETER HIV randomized clinical trial compared varenicline, cytisine, and nicotine replacement therapy on alcohol and smoking behavior among 400 PWH in Russia. The primary exposure was thirty-day point prevalence abstinence (PPA) from (1) alcohol, (2) smoking, (3) both, or (4) neither and was assessed at 1, 3, 6 and 12-months as were the study outcomes of anxiety (GAD-7) and depressive (CES-D) symptoms. The primary aim was to examine the association between smoking and/or alcohol abstinence and subsequent symptoms of depression and anxiety. Primary analysis used repeated measures generalized linear modeling to relate PPA with mental health scores across time. In secondary analyses, Kruskal-Wallis tests related PPA with mental health scores at each timepoint. Primary analyses did not identify significant differences in anxiety or depressive symptoms between exposure groups over time. Secondary analyses found CES-D scores across PPA categories were similar at 1-month (11, 10, 11, 11) and 6-months (10, 10, 11, 11) but differed at 3-months (9, 11, 10, 12; p = 0.035) and 12-months (10, 6, 11, 10; p = 0.019). GAD-7 scores did not vary across PPA categories at any time point. While abstinence was associated with fewer depressive symptoms at times, findings were not consistent during follow-up, perhaps reflecting intermittent relapse. PWH with polysubstance use and mental health comorbidity are complex, and larger samples with sustained abstinence would further elucidate effects of abstinence on mental health.

Abstract
BACKGROUND Varenicline is considered one of the most effective treatment options for smoking cessation. Nonetheless, it is only modestly effective. A deeper comprehension of the effects of varenicline by means of the in-depth review of relevant fMRI studies may assist in paving the development of more targeted and effective treatments. METHODOLOGY A search of PubMed and Google Scholar databases was conducted with the keywords "functional magnetic resonance imaging" or "fMRI", and "varenicline". All peer-reviewed articles regarding the assessment of smokers with fMRI while undergoing treatment with varenicline and meeting the predefined criteria were included. RESULTS Several studies utilizing different methodologies and targeting different aspects of brain function were identified. During nicotine withdrawal, decreased mesocorticolimbic activity and increased amygdala activity, as well as elevated amygdala-insula and insula-default-mode-network functional connectivity are alleviated by varenicline under specific testing conditions. However, other nicotine withdrawal-induced changes, including the decreased reward responsivity of the ventral striatum, the bilateral dorsal striatum and the anterior cingulate cortex are not influenced by varenicline suggesting a task-dependent divergence in neurocircuitry activation. Under satiety, varenicline treatment is associated with diminished cue-induced activation of the ventral striatum and medial orbitofrontal cortex concomitant with reduced cravings; during the resting state, varenicline induces activation of the lateral orbitofrontal cortex and suppression of the right amygdala. CONCLUSIONS The current review provides important clues with regard to the neurobiological mechanism of action of varenicline and highlights promising research opportunities regarding the development of more selective and effective treatments and predictive biomarkers for treatment efficacy.

Abstract
BACKGROUND AND AIMS iCanQuit is a smartphone application (app) proven efficacious for smoking cessation in a Phase III randomized controlled trial (RCT). This study aimed to measure whether medications approved by the US Food and Drug Administration (FDA) for smoking cessation would further enhance the efficacy of iCanQuit, relative to its parent trial comparator-the National Cancer Institute's (NCI's) QuitGuide app. DESIGN Secondary analysis of the entire parent trial sample of a two-group (iCanQuit and QuitGuide), stratified, doubled-blind RCT. SETTING United States. PARTICIPANTS Participants who reported using an FDA-approved cessation medication on their own (n = 619) and those who reported no use of cessation medications (n = 1469). INTERVENTIONS Participants were randomized to receive iCanQuit app or NCI's QuitGuide app. MEASUREMENTS Use of FDA-approved medications was measured at 3 months post-randomization. Smoking cessation outcomes were measured at 3, 6 and 12 months. The primary outcome was 12-month self-reported 30-day point prevalence abstinence (PPA). FINDINGS The data retention rate at the 12-month follow-up was 94.0%. Participants were aged 38.5 years, 71.0% female, 36.6% minority race/ethnicity, 40.6% high school or less education, residing in all 50 US States and smoking 19.2 cigarettes/day. The 29.6% of all participants who used medications were more likely to choose nicotine replacement therapy (NRT; 78.8%) than other cessation medications (i.e. varenicline or bupropion; 18.3 and 10.5%, respectively) and use did not differ by app treatment assignment (all P > 0.05). There was a significant (P = 0.049) interaction between medication use and app treatment assignment on PPA. Specifically, 12-month quit rates were 34% for iCanQuit versus 20% for QuitGuide [odds ratio (OR) = 2.36, 95% confidence interval (CI) = 1.59, 3.49] among participants reporting any medication use, whereas among participants reporting no medication use, quit rates were 28% for iCanQuit versus 22% for QuitGuide (OR = 1.41, 95% CI = 1.09, 1.82). Results were stronger for those using only NRT: 40% quit rates for iCanQuit versus 18% quit rates for QuitGuide (OR = 3.57, 95% CI = 2.20, 5.79). CONCLUSIONS The iCanQuit smartphone app for smoking cessation was more efficacious than the QuitGuide smartphone app, regardless of whether participants used medications to aid cessation. Smoking cessation medications, especially nicotine replacement therapy, might enhance the efficacy of the iCanQuit app.

Abstract
INTRODUCTION Cigarette smoke accounts for over 90,000 deaths each year in Italy. Tobacco dependence treatment guidelines suggest adopting an integrated pharmacological-behavioral model of intervention. Cytisine is a partial agonist of nicotinic receptors. Trials conducted to date have demonstrated its good efficacy in promoting smoking cessation. The cytisine scheme of treatment consists of 25 days of treatment. A 40-day regimen, with an escalating dose and an extended duration of the treatment, has been in use in many anti-smoking centers in Italy for several years, but to date there are no reports on the use of cytisine with this scheme. METHODS A retrospective, real-life, observational study was conducted between January 2016 and September 2022. The 300 patients who had received at least one dose of study medication were selected. Continuous variables were compared by the Wilcoxon-Mann-Whitney test. Univariate and multivariate logistic regression models were implemented for self-reported seven-day point prevalence for abstinence at three, six and 12 months. RESULTS The median age of the patients was 59 years, 57% were women. The median smoking exposure was 33.8 pack-years. Self-reported smoking abstinence at three, six and 12 months was 68.7%, 56.3% and 47.3% respectively. 84% completed the cytisine treatment, 31.3% reported adverse events and in 8.3% these led to dropping out of the treatment. CONCLUSION Cytisine, administered with a novel therapeutic scheme in the real-life setting of a specialized anti-smoking center, significantly promotes smoking abstinence. However, more studies are needed to assess the tolerability and efficacy of this new regimen.

Abstract
BACKGROUND Adhering to varenicline has been shown to significantly improve the chances of successfully quitting smoking, with studies indicating a twofold increase in 6-month quit rates. However, despite its potential benefits, many individuals struggle with maintaining good adherence to varenicline; thus there is a need to develop scalable strategies to help people adhere. As a first step to inform the development of an intervention to improve adherence to varenicline, we conducted a rapid literature review to identify: 1) modifiable barriers and facilitators to varenicline adherence, and 2) behaviour change techniques associated with increased adherence to varenicline. METHODS We searched MEDLINE, Embase, APA PsycINFO, CINAHL, and the Cochrane Central Register of Controlled Trials for relevant studies published between 2006 and 2022. Search terms included "varenicline," "smoking cessation," and "adherence," and their respective subject headings and synonyms. We screened and included studies reporting modifiable determinants of adherence to varenicline and then assessed quality, extracted modifiable determinants and mapped them to the Theoretical Domains Framework version 2 and the Behaviour Change Technique Taxonomy version 1. RESULTS A total of 1,221 titles were identified through the database searches; 61 met the eligibility criteria. Most of the studies were randomized controlled trials and predominantly focused on barriers to varenicline. Only nine studies explicitly mentioned behaviour change techniques used to help varenicline adherence. Eight domains were identified as barriers to varenicline adherence (behavioural regulation, memory, goals, intentions, beliefs about capabilities, beliefs about consequences, optimism/pessimism, and environmental context) and five as facilitators (knowledge, behavioural regulation, beliefs about capabilities, social influences, and environmental context). CONCLUSIONS This study identifies barriers and facilitators that should be addressed when developing a complex adherence intervention tailored to patients' needs based on modifiable determinants of medication adherence, some of which are under- used by existing adherence interventions. The findings from this review will inform the design of a theory-based healthbot planned to improve varenicline adherence in people undergoing smoking cessation treatment. SYSTEMATIC REVIEW REGISTRATION This study was registered with PROSPERO (# CRD42022321838).

Abstract
Importance Electronic cigarettes (ECs) are often used by smokers as an aid to stopping smoking, but evidence is limited regarding their efficacy compared with nicotine replacement therapy (NRT), and no evidence is available on how their efficacy compares with that of varenicline. Objective To evaluate whether ECs are superior to NRT and noninferior to varenicline in helping smokers quit. Design, Setting, and Participants This was a randomized clinical trial conducted at 7 sites in China and including participants who were smoking at least 10 cigarettes per day and motivated to quit, not using stop-smoking medications or EC, and willing to use any of the study products. Participants were first recruited in May 2021, and data analysis was conducted in December 2022. Interventions A cartridge-based EC (30 mg/mL nicotine salt for 2 weeks and 50 mg/mL after that), varenicline (0.5 mg, once a day for 3 days; 0.5 mg, twice a day for 4 days; and 1 mg, twice a day, after that), and 2 mg (for smokers of ≤20 cigarettes per day) or 4 mg (>20 cigarettes per day) nicotine chewing gum, all provided for 12 weeks and accompanied by minimal behavioral support (an invitation to join a self-help internet forum). Main Outcomes and Measures The primary outcome was sustained abstinence from smoking at 6 months as validated by an expired-air carbon monoxide reading (<8 parts per million). Participants lost to follow-up were included as nonabstainers. Results Of 1068 participants, 357 (33.5%) were female, and the mean (SD) age was 33.9 (3.1) years. A total of 409 (38.3%), 409 (38.3%), and 250 (23.4%) participants were randomized to the EC, varenicline, and NRT arms, respectively. The 6-month biochemically validated abstinence rates were 15.7% (n = 64), 14.2% (n = 58), and 8.8% (n = 22) in the EC, varenicline, and NRT study arms, respectively. The quit rate in the EC arm was noninferior to the varenicline arm (absolute risk reduction, 1.47%; 95% CI, -1.41% to 4.34%) and higher than in the NRT arm (odds ratio, 1.92; 95% CI, 1.15-3.21). Treatment adherence was similar in all study arms during the initial 3 months, but 257 participants (62.8%) in the EC arm were still using ECs at 6 months, with no further use in the 2 other study arms. The most common adverse reactions were throat irritation (32 [7.8%]) and mouth irritation (28 [6.9%]) in the EC arm, nausea (36 [8.8%]) in the varenicline arm, and throat irritation (20 [8.0%]) and mouth irritation (22 [8.8%]) in the NRT arm. No serious adverse events were recorded. Conclusions and Relevance The results of this randomized clinical trial found that when all treatments were provided with minimal behavior support, the efficacy of EC was noninferior to varenicline and superior to nicotine chewing gum.

Abstract
RATIONALE Screening novel medications for alcohol use disorder (AUD) requires models that are both efficient and ecologically-valid. Ideally, such models would be associated with the outcomes of a given medication in clinical trials. OBJECTIVES To test a novel human laboratory model in which individuals with intrinsic motivation to change their drinking engage in a "practice quit" attempt consisting of 6 days of complete abstinence from alcohol. METHOD Individuals with current AUD completed a randomized, double-blind, placebo-controlled study of naltrexone (50 mg), varenicline (2 mg bid), or matched placebo. Participants were titrated onto the study medication for 1 week prior to starting the 6-day practice quit attempt. During the practice quit attempt, participants completed daily interviews with research staff. All participants completed an alcohol cue-exposure paradigm before starting the study medication and after 2 weeks of study medication. RESULTS There were no significant medication effect on drinks per drinking day (F(2,49) = 0.66, p = 0.52) or percent days abstinent (F(2,49) = 0.14, p = 0.87) during the 6-day practice quit period. There were no medication effects on alcohol cue-reactivity (F(2,44) = 0.80, p = 0.46). Notably, participants sharply reduced their drinking during the entire 13-day medication treatment period, as compared to reducing only during the 6-day practice quit period. During the total medication period, higher levels of motivation to change was associated with higher percent days abstinent (F(1,49) = 8.12, p < 0.01). CONCLUSIONS This study reports mostly null findings, which challenges us to decompose its nuanced design to consider model refinements. Possible changes to the model include considering the requirement for intrinsic motivation for change, including a longer practice quit period, encompassing the medication administration timeframe in the practice quit period, increasing the required sample size for signal detection, and examining a post COVID-19 pandemic cohort.

Abstract
Current strategies for smoking withdrawal conditions involve monotherapy of nicotine and combinational therapy of nicotine with varenicline or bupropion as per the CDC and FDA. The available dosage forms for nicotine are patches, gums, inhalers and nasal sprays, bupropion and varenicline are available in tablet form. This research work focused on developing a microneedle delivery system to deliver combination drug for overcoming the obstacles encountered by oral route of administration of varenicline such as severe side effects (mood swings, agitation, depressed behaviour, seizures, etc), and nicotine therapy challenges such as short half-life, repeated dosing, nausea, and vomiting. The nanoparticles of nicotine prepared by nanoprecipitation method showed particle size PTZ (356.6 ± 65.98), percentage entrapment efficiency (35.55 % ± 0.007), in-vitro drug release (47.89 % ± 0.7) for 72 h. Microneedles showed height (600 μm), width (350 μm), and tip diameter (10 μm). The nanoparticles encapsulated in microneedles showed in-vitro sustained delivery of nicotine (67.00 % ± 4.92) and varenicline (79.78 % ± 1.09) in 48 h. Nicotine released in a sustained manner attaches to the nicotine acetylcholine receptors (nAchR) to release dopamine for controlling the withdrawal challenges such as anxiety, irritability, cravings, disturbed sleep pattern, etc. The varenicline released from microneedles binds to the nAchR and inhibits dopamine release responsible for the euphoric effect induced by nicotine, and thus assists in curbing the nicotine withdrawal symptoms. This combination microneedle system offers prolonged treatment in a single application for smoking withdrawal conditions wherein patients are not in stage of oral dosing because of repeated dosing resulting in adverse effects like seizures, hypertension, sleep disturbances, insomnia, and nausea.

Abstract
BACKGROUND Alcohol Use Disorder (AUD) is a major cause of premature death, disability and suffering. Available treatments are of modest efficacy and under-prescribed so there is a pressing need for a well-tolerated and effective treatment option for AUD. Dopamine is hypothesized to be involved in the development of alcohol dependence. To challenge the low-dopamine hypothesis of addiction, this randomized, double-blind, placebo-controlled, 13-week, multicentre clinical trial with four parallel arms is designed to evaluate the efficacy of two substances raising dopamine levels, varenicline and bupropion, alone and in combination vs. placebo on alcohol consumption in AUD. Varenicline, a partial agonist at brain nicotinic acetylcholine receptors increases dopamine release, whereas bupropion is a centrally-acting, norepinephrine-dopamine reuptake inhibitor. Varenicline is previously shown to reduce alcohol intake in individuals with AUD. We hypothesize that the effect size of a combination of two drugs affecting dopamine levels in the brain will exceed that of approved AUD therapies. METHODS Consenting individuals with AUD will be recruited via media advertisements. Those fulfilling the eligibility criteria (N = 380) will be randomized to one of four interventions (n = 95 per arm). Treatment will comprise one week of titration (varenicline 0.5‒2 mg; bupropion SR 150‒300 mg) plus 12 weeks at steady state. Efficacy will be evaluated using two primary endpoints of alcohol consumption: Heavy Drinking Days and blood levels of phosphatidylethanol. Secondary objectives, exploratory and subgroup analyses will be also performed. The modified Intention-to-Treat and Per Protocol datasets will be evaluated using Analysis of Covariance. Last patient out is estimated to occur in December, 2022. DISCUSSION The COMB Study aims to evaluate the efficacy of the combination of varenicline and bupropion, two drugs affecting dopamine, on alcohol consumption, and to challenge the low-dopamine hypothesis of addiction.

Abstract
INTRODUCTION People who smoke cigarettes are more likely than people who do not to use cannabis, including blunts, a tobacco product containing nicotine and marijuana. Blunts represent a challenge for cessation trials because nicotine could make stopping cigarettes more difficult. Few studies have examined the impact of blunt use on individuals actively engaged in a cigarette quit attempt. METHODS Blunt use was assessed at baseline, Weeks 4, 8, 12, 16, and 26 among Black adult people who smoke enrolled in a double-blind, placebo-controlled, randomized trial of varenicline (VAR, n = 300) versus placebo (PBO, n = 200) for smoking cessation. Participants were categorized as ever blunt (blunt use reported at any timepoint) versus non-blunt (no blunt use reported). The primary outcome was salivary cotinine-verified 7-day point prevalence smoking abstinence at Weeks 12 and 26. Logistic regression examined the effects of treatment and blunt use on abstinence. RESULTS 75 participants (mean age 45.6 years (SD = 12.5, range: 22,80); 32 (42%) female) reported blunt use. Logistic regression analyses showed no treatment by blunt use interaction or significant main effect of blunt use on smoking abstinence at Weeks 12 or 26 (p > 0.05). After adjusting for treatment, those who used blunts had statistically similar odds of quitting at Week 12 (OR: 0.68, 95% CI: 0.31, 1.5) and Week 26 (OR: 0.84, 95% CI: 0.38, 1.87) as those who never used blunts during the study. DISCUSSION Blunt use had no statistically significant impact on cessation among participants in a smoking cessation clinical trial. Future trials are needed in which the target of cessation is all combustible products.

Abstract
BACKGROUND People with serious mental illness (SMI; bipolar [BD] or schizophrenia spectrum disorders [SSD]) who smoke have 30-60% lower odds of quitting and are more prone to experience neuropsychiatric adverse events (NPSAEs) when quitting than smokers without SMI. We pilot-tested the feasibility of combining two different dosing strategies of varenicline preloading with Acceptance and Commitment Therapy (ACT) in persons with SMI in an attempt to bolster quit rates without increasing NPSAEs. METHODS Twelve-week, single center, randomized, double-blind, pilot feasibility trial of low (0.5mg twice daily, slower titration) versus standard dose (1.0mg twice daily, standard titration) varenicline in persons with BD or SSD with a 12-week follow-up. All participants received up to 10 sessions of ACT for smoking cessation. Participants were asked to preload with varenicline while still smoking and set a flexible target quit day (TQD) by day 35. RESULTS Recruitment was hampered by shutdowns related to COVID-19 and the worldwide varenicline recall, respectively. Retention goals were met. Treatment satisfaction was high across both dosing and diagnostic groups. Most participants (92.9%) adhered to preloading instructions and the flexible TQD. Seven-day point prevalence abstinence at week 12 was highest in BD participants (37.5%) but lowest in SSD participants (16.7%) who received the standard dose. Medication was well tolerated. CONCLUSIONS Although recruitment was hindered by unanticipated world events, feasibility was demonstrated. Participants adhered to and were highly satisfied with the combination of pre-cessation varenicline plus ACT. Findings support testing this combined treatment approach in a fully powered trial of persons with BD who smoke.

Abstract
Objective: To examine the literature pertaining to safety and efficacy of intranasal (IN) varenicline for the treatment of dry eye disease (DED). Data Sources: A literature search of PubMed was performed (1985 to January 2022) using the following search terms: varenicline, OC-01, intranasal, and dry eye. Additional data were acquired from references of identified articles, prescribing information, government databases, and manufacturer website. Study Selection/Data Extraction: All relevant English-language studies were included in this review. Data Synthesis: IN varenicline was FDA approved for the treatment of DED in 2021. IN varenicline has demonstrated a statistically significant improvement in outcomes related to basal tear film production as measured by a Schirmer test score (STS) in data from phase 2 and 3 clinical trials. Safety data from these trials have demonstrated that IN varenicline is generally well tolerated with minimal ocular side effects. The most common side effects reported in the trials were sneezing, coughing, along with throat and nasal irritation. Relevance to Patient care and Clinical Practice: Patients suffering from DED have been traditionally treated with ophthalmic preparations; however, many patients struggle with proper administration of ophthalmic products. IN varenicline stimulates nicotinic cholinergic receptors and basal tear film production through the trigeminal parasympathetic nerve pathway (TPP). There is no evidence to support the long-term remission of DED symptoms with IN varenicline as seen with anti-inflammatory modulators. Conclusions: IN varenicline offers an effective and novel approach to management of DED for patients who desire a non-ophthalmic preparation with a favorable side effect profile.

Abstract
OBJECTIVE To investigate the most effective and best-tolerated drugs for treating diseased smokers. METHODS Eight databases were searched for randomized controlled trials (RCTs) involving different pharmacological interventions for smoking cessation in disease patients (January 2023). Network meta-analysis was performed using STATA 15.1 software. The Cochrane Risk of Bias Tool assessed the risk of bias, and confidence in evidence was assessed using CINeMA. RESULTS A total of 60 RCTs involving 13,009 patients of 12 disease categories were included. All trials reported 13 interventions, resulting in 78 comparisons. Network meta-analysis showed that varenicline (OR = 2.30, 95% CI (1.77, 3.00)) and bupropion (OR = 1.65, 95% CI (1.29, 2.11)) showed favorable abstinence effects compared to placebo in the cardiovascular disease population. Nicotine replacement therapy (NRT) had better withdrawal advantages than placebo (OR = 11.18, 95% CI (2.25, 55.54)) in the chronic obstructive pulmonary disease (COPD) population. Some combination treatments showed better results than monotherapy, such as bupropion + NRT was superior to bupropion (OR = 8.45, 95% CI (1.84, 38.89)) and NRT (OR = 4.98, 95% CI (1.25, 19.78)) in mental illness population. The final surface under the cumulative ranking curve indicated that bupropion + NRT achieved the best smoking cessation effect. Overall confidence in the evidence was low. In a comparison of drugs, the results showed that bupropion + NRT had the best safety. CONCLUSIONS Most interventions show the benefit of quitting smoking compared with placebo, including monotherapy and combination therapy. Moreover, varenicline or bupropion combined with NRT is superior to some monotherapies.

Abstract
Background: Brief therapies have proven to reduce tobacco cost-effectively, however, unsuccessful quit attempts remain notable in real-life conditions, and the underlying mechanisms of treatment success are still unclear. Objectives: We aimed to analyze the effectiveness of the Guided Self-Change (GSC) therapy combined with varenicline (VAR+T) in public health services against varenicline alone (VAR), and to identify mediators of treatment outcomes. We conducted a two-arm quasi-experimental study with 126 treatment-seeking smokers (age=57.3±9.1 years; 59.5% women). Before treatment, and at weeks 12 and 24, we assessed tobacco use and five potential mediators: withdrawal, craving, motivation to quit, anxiety, and depression. Results: Only 25% of participants adhered to varenicline prescription, and 54% to GSC therapy. VAR+T group showed a greater proportion of abstainers compared to VAR group at week 12 (75% vs 57.4%; φc=0.21) and week 24 (62.9% vs 52.5%; φc=0.10). When controlling for weeks taking varenicline, motivation showed a significant indirect effect over abstinence rates in VAR+T compared with VAR (a1b1=1.34; 95%CI=0.04, 5.03). Conclusions: The GSC effectiveness seems to increase motivation which in turn contributes to reducing tobacco use. The implementation of GSC therapy in public health services could minimize treatment duration and increase smoking abstinence in 'real-life' conditions where varenicline adherence remains low.

Abstract
BACKGROUND Varenicline is efficacious for smoking cessation, but a return to smokingusually occurs after treatment ends. Electronic nicotine delivery systems (ENDS) may enhance smoking reduction and cessation by providing a behavioral substitute for smoking and may deter smoking in the long term if an individual's nicotine dependence can be transferred to ENDS. The goal of this study was to evaluate varenicline in conjunction with ENDS to promote switching to ENDS. METHODS Twenty-five individuals who smoked cigarettes, interested in switching but not seeking cessation treatment, received ENDS for 13 weeks; during weeks 2-13 they received varenicline. Assessments included self-reported cigarette and ENDS use, expired air carbon monoxide (CO), reward ratings, tolerability/side effects, and dependence measures. RESULTS Cigarette smoking decreased from 15.6 cigarettes/day (SD=5.6) at baseline to 2.8 cigarettes/day (SD=5.1) at week 13 (paired t(22)=10.24, p<0.0001). 28% of participants were confirmed to be abstinent in the last 4 weeks of treatment. ENDS use remained relatively constant, averaging 11.8 occasions per day (SD=10.6). Cigarette dependence (assessed by time to first use of the day) decreased after introduction of ENDS (paired t(23) = -3.27, p=0.003), and again after the first week of full-dose varenicline (paired t(23) = -4.27, p=0.0003). Dependence on ENDS did not change, starting out lower than cigarettes (paired t(21) = 5.52, p<0.0001), but ending higher (paired t(22) = 2.94, p=0.008). Smoking satisfaction declined markedly, while satisfaction for ENDS remained relatively constant. Treatment tolerability and adherence were high. CONCLUSIONS ENDS in combination with varenicline shows promise as a means to reduce dependence on cigarettes and facilitate switching from cigarettes to ENDS.

Abstract
INTRODUCTION There are multiple systematic reviews and meta-analyses on the efficacy and safety of pharmacological treatments against nicotine dependence. However, there are few guidelines to answer frequent questions asked by a clinician treating a smoker. Therefore, the aim of this paper is to facilitate the treatment of tobacco addiction. MATERIAL AND METHODS 12 PICO questions are formulated from a GLOBAL PICO question: "Efficacy and safety of pharmacological treatment of tobacco dependence". A systematic review was carried out to answer each of the questions and recommendations were made. The GRADE (Grading of Recommendations, Assessment, Development and Evaluation) system was used to grade the certainty of the estimated effects and the strength of the recommendations. RESULTS Varenicline, nicotine replacement therapy (NRT), bupropion and cytisine are more effective than placebo. Varenicline and combined nicotine therapy are superior to the other therapies. In smokers with high dependence, a combination of drugs is recommended, being more effective those associations containing varenicline. Other optimization strategies with lower efficacy consist of increasing the doses, the duration, or retreat with varenicline. In specific populations varenicline or NRT is recommended. In hospitalized, the treatment of choice is NRT. In pregnancy it is indicated to prioritize behavioral treatment. The financing of smoking cessation treatments increases the number of smokers who quit smoking. There is no scientific evidence of the efficacy of pharmacological treatment of smoking cessation in adolescents. CONCLUSIONS The answers to the 12 questions allow us to extract recommendations and algorithms for the pharmacological treatment of tobacco dependence.

Abstract
BACKGROUND Smoking is a strong risk factor for patients with acute myocardial infarction (AMI). Varenicline is commonly used as a smoking cessation medication, but little is known about its usage in patients with AMI, particularly in hospitalized patients. METHODS This is a prospective observational, single-center study collected from May 2018 to July 2021. Study patients underwent percutaneous coronary intervention for AMI. The primary end point was set as safety of varenicline, focusing on any serious adverse cardiac events within 24 weeks after treatment. Efficacy of smoking abstinence was also assessed through self-reports of complete abstinence over a week before the 24- week clinic visit. RESULTS A total of 162 patients hospitalized with AMI were enrolled in our study. Mean age was 56.7 ± 9.95 years and 97% of the patients were male. Most patients (93.2%) received their first dose of varenicline during hospitalization. Time from admission to first dose of study medication was 2.31 ± 2.73 days and duration of drug intake was 7.41 ± 5.18 weeks. At week 24, only one patient had recurrent myocardial infarction, five patients had undergone revascularization for target lesion failure, and no additional patients developed stroke or died. In terms of efficacy, the rate of smoking abstinence was 79%. Light smokers found it easier to quit smoking than heavy smokers. CONCLUSION This study may represent the first report on the safety and efficacy of early initiation of varenicline treatment in East Asian population hospitalized due to AMI who recently underwent percutaneous coronary intervention.

Abstract
BACKGROUND Tobacco smoking is the leading preventable cause of death and disease worldwide. Stopping smoking can reduce this harm and many people would like to stop. There are a number of medicines licenced to help people quit globally, and e-cigarettes are used for this purpose in many countries. Typically treatments work by reducing cravings to smoke, thus aiding initial abstinence and preventing relapse. More information on comparative effects of these treatments is needed to inform treatment decisions and policies. OBJECTIVES To investigate the comparative benefits, harms and tolerability of different smoking cessation pharmacotherapies and e-cigarettes, when used to help people stop smoking tobacco. SEARCH METHODS We identified studies from recent updates of Cochrane Reviews investigating our interventions of interest. We updated the searches for each review using the Cochrane Tobacco Addiction Group (TAG) specialised register to 29 April 2022. SELECTION CRITERIA We included randomised controlled trials (RCTs), cluster-RCTs and factorial RCTs, which measured smoking cessation at six months or longer, recruited adults who smoked combustible cigarettes at enrolment (excluding pregnant people) and randomised them to approved pharmacotherapies and technologies used for smoking cessation worldwide (varenicline, cytisine, nortriptyline, bupropion, nicotine replacement therapy (NRT) and e-cigarettes) versus no pharmacological intervention, placebo (control) or another approved pharmacotherapy. Studies providing co-interventions (e.g. behavioural support) were eligible if the co-intervention was provided equally to study arms. DATA COLLECTION AND ANALYSIS We followed standard Cochrane methods for screening, data extraction and risk of bias (RoB) assessment (using the RoB 1 tool). Primary outcome measures were smoking cessation at six months or longer, and the number of people reporting serious adverse events (SAEs). We also measured withdrawals due to treatment. We used Bayesian component network meta-analyses (cNMA) to examine intervention type, delivery mode, dose, duration, timing in relation to quit day and tapering of nicotine dose, using odds ratios (OR) and 95% credibility intervals (CrIs). We calculated an effect estimate for combination NRT using an additive model. We evaluated the influence of population and study characteristics, provision of behavioural support and control arm rates using meta-regression. We evaluated certainty using GRADE. MAIN RESULTS Of our 332 eligible RCTs, 319 (835 study arms, 157,179 participants) provided sufficient data to be included in our cNMA. Of these, we judged 51 to be at low risk of bias overall, 104 at high risk and 164 at unclear risk, and 118 reported pharmaceutical or e-cigarette/tobacco industry funding. Removing studies at high risk of bias did not change our interpretation of the results. Benefits We found high-certainty evidence that nicotine e-cigarettes (OR 2.37, 95% CrI 1.73 to 3.24; 16 RCTs, 3828 participants), varenicline (OR 2.33, 95% CrI 2.02 to 2.68; 67 RCTs, 16,430 participants) and cytisine (OR 2.21, 95% CrI 1.66 to 2.97; 7 RCTs, 3848 participants) were associated with higher quit rates than control. In absolute terms, this might lead to an additional eight (95% CrI 4 to 13), eight (95% CrI 6 to 10) and seven additional quitters per 100 (95% CrI 4 to 12), respectively. These interventions appeared to be more effective than the other interventions apart from combination NRT (patch and a fast-acting form of NRT), which had a lower point estimate (calculated additive effect) but overlapping 95% CrIs (OR 1.93, 95% CrI 1.61 to 2.34). There was also high-certainty evidence that nicotine patch alone (OR 1.37, 95% CrI 1.20 to 1.56; 105 RCTs, 37,319 participants), fast-acting NRT alone (OR 1.41, 95% CrI 1.29 to 1.55; 120 RCTs, 31,756 participants) and bupropion (OR 1.43, 95% CrI 1.26 to 1.62; 71 RCTs, 14,759 participants) were more effective than control, resulting in two (95% CrI 1 to 3), three (95% CrI 2 to 3) and three (95% CrI 2 to 4) additional quitters per 100 respectively. Nortriptyline is probably associated with higher quit rates than control (OR 1.35, 95% CrI 1.02 to 1.81; 10 RCTs, 1290 participants; moderate-certainty evidence), resulting in two (CrI 0 to 5) additional quitters per 100. Non-nicotine/placebo e-cigarettes (OR 1.16, 95% CrI 0.74 to 1.80; 8 RCTs, 1094 participants; low-certainty evidence), equating to one additional quitter (95% CrI -2 to 5), had point estimates favouring the intervention over control, but CrIs encompassed the potential for no difference and harm. There was low-certainty evidence that tapering the dose of NRT prior to stopping treatment may improve effectiveness; however, 95% CrIs also incorporated the null (OR 1.14, 95% CrI 1.00 to 1.29; 111 RCTs, 33,156 participants). This might lead to an additional one quitter per 100 (95% CrI 0 to 2). Harms There were insufficient data to include nortriptyline and non-nicotine EC in the final SAE model. Overall rates of SAEs for the remaining treatments were low (average 3%). Low-certainty evidence did not show a clear difference in the number of people reporting SAEs for nicotine e-cigarettes, varenicline, cytisine or NRT when compared to no pharmacotherapy/e-cigarettes or placebo. Bupropion may slightly increase rates of SAEs, although the CrI also incorporated no difference (moderate certainty). In absolute terms bupropion may cause one more person in 100 to experience an SAE (95% CrI 0 to 2). AUTHORS' CONCLUSIONS The most effective interventions were nicotine e-cigarettes, varenicline and cytisine (all high certainty), as well as combination NRT (additive effect, certainty not rated). There was also high-certainty evidence for the effectiveness of nicotine patch, fast-acting NRT and bupropion. Less certain evidence of benefit was present for nortriptyline (moderate certainty), non-nicotine e-cigarettes and tapering of nicotine dose (both low certainty). There was moderate-certainty evidence that bupropion may slightly increase the frequency of SAEs, although there was also the possibility of no increased risk. There was no clear evidence that any other tested interventions increased SAEs. Overall, SAE data were sparse with very low numbers of SAEs, and so further evidence may change our interpretation and certainty. Future studies should report SAEs to strengthen certainty in this outcome. More head-to-head comparisons of the most effective interventions are needed, as are tests of combinations of these. Future work should unify data from behavioural and pharmacological interventions to inform approaches to combined support for smoking cessation.

Abstract
BACKGROUND Combining short-acting nicotine replacement therapy with varenicline increases smoking cessation rates compared with varenicline alone, but not all people tolerate these medications or find them helpful. We aim to investigate the therapeutic potential of an analogous combination, by evaluating the effectiveness, safety, and acceptability of combining nicotine salt e-cigarettes with cytisine, compared to nicotine salt e-cigarettes or cytisine only, on smoking abstinence at six months. METHODS A pragmatic, community-based, investigator-blinded, randomised superiority trial design will be utilised. Eligible participants will be people who smoke daily (N = 800, 90% power) from throughout New Zealand, who are: aged ≥ 18 years, motivated to quit in the next two weeks, able to provide online consent, willing to use e-cigarettes and/or cytisine, and have daily access to a mobile phone. Recruitment will utilise multi-media advertising. Participants will be randomised (3:3:2 ratio) to 12 weeks of: 1) e-cigarettes (closed pod system, 3% nicotine salt, tobacco flavour) plus cytisine; 2) e-cigarettes alone, or 3) cytisine alone. All groups will receive a six-month, text-message-based behavioural support programme. The primary outcome is self-reported, biochemically verified, continuous abstinence at six months post-quit date. Secondary outcomes, measured at quit date, then one, three, six, and 12 months post-quit date, include self-reported continuous abstinence, 7-day point prevalence abstinence, cigarettes smoked per day, withdrawal and urge to smoke, time to (re)lapse, treatment use and compliance, treatment crossover, dual-use, use of other cessation products, change in e-cigarette products, continuation of product use, acceptability, change in health state, health-related quality of life, change in body mass index, adverse events, and cost per quitter. DISCUSSION Pragmatic trials are of particular value as they reflect the 'real world' impact of interventions. The trial will provide some of the first evidence on the effectiveness of combining nicotine salt e-cigarettes with cytisine for smoking cessation, in a country with strong tobacco control policy. Findings will be incorporated into relevant systematic reviews, informing practice and policy. TRIAL REGISTRATION NCT05311085 ClinicalTrials.gov. Registered 5th April, 2022.

Abstract
Importance Adaptive pharmacotherapy, ie, starting a medication regimen and then modifying that regimen based on patient response, is common in many medical domains but is not common in smoking cessation. Recently, studies have found that adaptive treatment using precessation nicotine patches is efficacious for smoking cessation; however, adaptive treatment using precessation varenicline and adaptive treatment in clinical practice settings have not been fully assessed. Objective To determine whether adaptive pharmacotherapy leads to higher smoking abstinence rates than standard pharmacotherapy in a clinical practice setting. Design, Setting, and Participants This double-blinded stratified placebo-controlled randomized clinical trial compared adaptive treatment with standard treatment for smoking cessation. The study was conducted at a university health system in Durham, North Carolina, from February 2018 to May 2020 and was stopped early due to COVID-19. Data were analyzed as intent-to-treat from May 24, 2021, to February 27, 2022. Interventions Participants were allowed to choose varenicline or nicotine patches and were then randomized to adaptive or nonadaptive (standard) treatment. Participants started on their chosen medication (adaptive) or placebo (standard) 4 weeks before their target quit day. Two weeks later, participants were assessed for treatment response. Adaptive participants who did not decrease daily cigarettes smoked by at least 50% (nonresponders) received bupropion in addition to their chosen medication. Participants in the adaptative treatment group who did decrease daily cigarettes smoked by at least 50% (responders) and participants in the standard treatment group received additional placebo bupropion. Participants in the standard treatment group received varenicline starting 1 week before the target quit date or nicotine patches starting on the target quit day. All participants received brief behavioral support. Main Outcome and Measures The main outcome was biochemically verified 30-day continuous smoking abstinence 12 weeks after their target quit smoking day. Other measures included demographic characteristics, smoking history, and repeated smoking assessments. Results Of the planned 300 participants, a total of 188 participants (mean [SD] age, 49.1 [12.5] years; 102 [54%] female) were enrolled before the trial was stopped because of the COVID-19 pandemic. A total of 127 participants chose to use varenicline, including 64 randomized to adaptive treatment and 63 randomized to standard treatment, and 61 participants chose to use nicotine patches, including 31 randomized to adaptive treatment and 30 randomized to standard treatment. At baseline, participants smoked a mean (SD) of 15.4 (7.3) cigarettes per day. At 12 weeks after the target quit day, biochemically verified 30-day continuous smoking abstinence was observed in 23 of 95 participants (24%) in the adaptive treatment group and 8 of 93 participants (9%) in the standard treatment (odds ratio [OR], 3.38; 95% CI, 1.43-7.99; P = .004); among participants who used varenicline, 30-day continuous abstinence was 18 participants (28%) in the adaptive treatment group, and 5 participants (8%) in the standard treatment group (OR, 4.54; 95% CI, 1.57-13.15); among participants who used nicotine patches, 30-day continuous abstinence was 5 participants (16%) in the adaptive treatment group and 3 participants (10%) in the standard treatment group (OR, 1.73; 95% CI, 0.38-7.99). Sleep problems were more common for participants in the varenicline adaptive treatment group than in the varenicline standard treatment group (rate ratio, 1.74; 95% CI, 1.18-2.58; P = .03). Conclusions and Relevance This randomized clinical trial found that adaptive pharmacotherapy was efficacious for smoking cessation treatment in a practice setting.

Abstract
BACKGROUND AND AIMS Treatment of depression-related psychological factors related to smoking behavior may improve rates of cessation among adults with major depressive disorder (MDD). This study measured the efficacy and safety of 12 weeks of behavioral activation for smoking cessation (BASC), varenicline and their combination. DESIGN, SETTING, PARTICIPANTS This study used a randomized, placebo-controlled, 2 × 2 factorial design comparing BASC versus standard behavioral treatment (ST) and varenicline versus placebo, taking place in research clinics at two urban universities in the United States. Participants comprised 300 hundred adult smokers with current or past MDD. INTERVENTIONS BASC integrated behavioral activation therapy and ST to increase engagement in rewarding activities by reducing avoidance, withdrawal and inactivity associated with depression. ST was based on the 2008 PHS Clinical Practice Guideline. Both treatments consisted of eight 45-min sessions delivered between weeks 1 and 12. Varenicline and placebo were administered for 12 weeks between weeks 2 and 14. MEASUREMENTS Primary outcomes were bioverified intent-to-treat (ITT) 7-day point-prevalence abstinence at 27 weeks and adverse events (AEs). FINDINGS No significant interaction was detected between behavioral treatment and pharmacotherapy at 27 weeks (χ2 (1) = 0.19, P = 0.67). BASC and ST did not differ (χ2 (1) = 0.43, P = 0.51). Significant differences in ITT abstinence rates (χ2 (1) = 4.84, P = 0.03) emerged among pharmacotherapy arms (16.2% for varenicline, 7.5% for placebo), with results favoring varenicline over placebo (rate ratio = 2.16, 95% confidence interval = 1.08, 4.30). All significant differences in AE rates after start of medication were higher for placebo than varenicline. CONCLUSION A randomized trial in smokers with major depressive disorder found that varenicline improved smoking abstinence versus placebo at 27 weeks without elevating rates of adverse events. Behavioral activation for smoking cessation did not outperform standard behavioral treatment, with or without adjunctive varenicline therapy.

Abstract
This review provides an overview of potential vaping-cessation interventions in adult former smokers. The interventions reviewed include varenicline, bupropion, nicotine-replacement therapies (NRTs), and behavioural therapy. Evidence for intervention effectiveness is provided when available, such as for varenicline, whereas recommendations for bupropion and NRT are extrapolated from case studies or smoking-cessation guidelines. The limitations of these interventions, a general lack of prospective studies, and a discussion of challenges to vaping safety from a public health perspective are also discussed. Although these interventions show promise, further research is needed to establish precise protocols and dosages in the context of vaping cessation, rather than adapting existing recommendations from smoking cessation.

Abstract
BACKGROUND Current smoking cessation treatments are limited in terms of efficacy, particularly with regards to long term abstinence. There is a large amount of evidence implicating the insula in nicotine addiction. OBJECTIVE To examine the efficacy of bilateral repetitive transcranial magnetic stimulation (rTMS) directed to the insular cortex with the H11 coil, relative to sham stimulation, on smoking abstinence and smoking outcomes in smokers who are receiving standard varenicline treatment. METHODS This randomized, double-blind, sham controlled trial recruited 42 participants who were randomized to receive either active (n = 24) or sham (n = 18) high frequency rTMS directed to the insula (4 weeks), while receiving varenicline treatment (12 weeks). The primary outcome was 7-day point prevalence abstinence at the end of 12 weeks. RESULTS Smokers in the active group had significantly higher abstinence rates than those in the sham group (82.4% vs. 30.7%, p = 0.013) at the end of treatment (Week 12). Secondary outcome measures of abstinence rate at the end of rTMS treatment (Week 4), abstinence rate at 6 months, and smoking outcomes (e.g., craving, withdrawal) showed no significant differences between groups. No differences were found in adverse events reported between the groups. CONCLUSION This study provides evidence of the potential benefit of having a combined treatment for smoking cessation using insula rTMS with the H11 coil and varenicline. Maintenance rTMS sessions and continuation of varenicline for those in abstinence may induce longer-term effects and should be considered in future studies.

INTRODUCTION A smoking-cessation program was implemented as a randomized non-inferiority trial in primary care practices in Croatia and Slovenia to investigate whether a standard 4-week treatment with cytisine was at least as effective and feasible as a standard 12-week treatment with varenicline in helping smokers quit. AIMS AND METHODS Out of 982 surveyed smokers, 377 were recruited to the non-inferiority trial: 186 were randomly assigned to cytisine and 191 to varenicline treatment. The primary cessation outcome was 7-day abstinence after 24 weeks, while the primary feasibility outcome was defined by adherence to the treatment plan. We also compared the rates of adverse events between the two treatment groups. RESULTS The cessation rate after 24 weeks was 32.46% (62/191) in the varenicline group and 23.12% (43/186) in the cytisine group (odds ratio [OR]: 95%, credible interval [CI]: 0.39 to 0.98). Of 191 participants assigned to varenicline treatment 59.16% (113) were adherent, while 70.43% (131 of 186) were adherent in the cytisine group (OR: 1.65, 95% CI: 1.07 to 2.56). Participants assigned to cytisine experienced fewer total (incidence rate ratio [IRR]: 0.59, 95% CI: 0.43 to 0.81) and fewer severe or more extreme adverse events (IRR: 0.72, 95% CI: 0.35 to 1.47). CONCLUSIONS This randomized non-inferiority trial (n = 377) found the standard 4-week cytisine treatment to be less effective than the standard 12-week varenicline treatment for smoking cessation. However, adherence to the treatment plan, ie, feasibility, was higher, and the rate of adverse events was lower among participants assigned to cytisine treatment. IMPLICATIONS The present study found the standard 12 weeks of varenicline treatment to be more effective than the standard 4 weeks of cytisine treatment for smoking cessation in a primary care setting in Croatia and Slovenia. Participants assigned to cytisine, however, had a higher adherence to the treatment plan and a lower rate of adverse events. Estimates from the present study may be especially suitable for generalizations to high-smoking prevalence populations in Europe. Given the much lower cost of cytisine treatment, its lower rate of adverse events, and higher feasibility (but its likely lower effectiveness with the standard dosage regimen), future analyses should assess the cost-effectiveness of the two treatments for health policy considerations.

Abstract
Aim: Herein, we report safety outcomes for varenicline solution nasal spray (VNS) within the context of clinical trial discontinuation, contrasting those with discontinuation outcomes from topical cyclosporine and lifitegrast clinical trials. Materials & methods: 1061 subjects were randomized across three clinical trials to receive either VNS 0.06 mg, VNS 0.03 mg, VNS 0.006 mg or vehicle control. Subjects who discontinued from treatment were noted and assigned to their appropriate categories. Results: Despite treatment emergent adverse events, 93.5% of subjects receiving VNS completed the treatment period. By comparison, only 80% of subjects in the integrated clinical trials for cyclosporine ophthalmic emulsion and 91% of subjects in the integrated trials for lifitegrast ophthalmic solution completed the full treatment period, respectively. Conclusion: In clinical trials, VNS demonstrated improvements in dry eye disease signs and symptoms, was well-tolerated, and had an overall completion rate >93%. Conventional dry eye treatments (e.g., cyclosporine and lifitegrast) noted considerably higher discontinuation rates in their clinical trials.

Abstract
INTRODUCTION Genetic variation in Cytochrome P450 2A6 (CYP2A6), the major nicotine metabolizing enzyme, is associated with nicotine dependence and smoking cessation. Nicotine dependence severity also predicts smoking cessation. Our goals were to determine how CYP2A6 variation and nicotine dependence alter smoking cessation, and whether dependence could refine CYP2A6-based treatment recommendations. AIMS AND METHODS Adult smokers treated for 12 weeks with placebo, nicotine patch, or varenicline (NCT01314001) were grouped as CYP2A6 normal (n = 567) or slow (n = 432) nicotine metabolizers based on a CYP2A6 weighted genetic risk score. Fagerström test for nicotine dependence scores were measured at baseline and biochemically verified smoking cessation was assessed at end of treatment. RESULTS Dependence neither mediated nor moderated an association between CYP2A6 variation and smoking cessation overall, within any treatment arm, or after stratifying by ancestry (n = 591 European, n = 408 African ancestry) or sex (n = 444 women, n = 555 men). In within-treatment analyses, the mediation effect odds ratio (OR) ranged from 0.95 to 1.00 and the bias-corrected 95% confidence interval contained 1. Moderation (i.e. interaction) effect ORs ranged from 0.88 to 1.61 (p = .397-.828). For CYP2A6 normal metabolizers, quit rates on varenicline were similar for those with high (41.1%) and low (43.4%) dependence, while quit rates were lower for those with high versus low dependence on both patch (16.5 vs. 29.7%) and placebo (8.9 vs. 18.5%). CYP2A6 slow metabolizers with high versus low dependence had lower quit rates in all three treatment arms. CONCLUSIONS Although nicotine dependence severity neither mediated nor moderated CYP2A6 associations with smoking cessation, incorporating information on dependence may optimize the choice of smoking cessation treatment aid in CYP2A6 normal and slow metabolizers. IMPLICATIONS Variation in CYP2A6 and nicotine dependence severity alter smoking cessation success. Our findings suggest that while nicotine dependence severity is unlikely to mediate or moderate CYP2A6 associations with cessation, incorporating patient information on both CYP2A6 and nicotine dependence severity may lead to improved smoking cessation strategies.

Abstract
OBJECTIVE This study examined trends in receipt of smoking cessation medications among smokers with and without mental illness, including serious mental illness, from 2005 to 2019 and characterized physician attitudes and practices related to tobacco screening and cessation treatment. METHODS Medical Expenditure Panel Survey (MEPS) data (2005-2019) were examined for receipt of cessation medication prescriptions for bupropion, varenicline, and nicotine replacement therapy (NRT) among 55,662 smokers-18,353 with any mental illness and 7,421 with serious mental illness. Qualitative interviews with 40 general internists and psychiatrists between October and November 2017 used a semistructured guide. MEPS data were analyzed with descriptive statistics, and interviews were analyzed with hybrid inductive-deductive coding. RESULTS From 2005 to 2019, at least 83% of smokers with or without mental illness did not receive varenicline, NRT, or bupropion. Over 14 years, the proportion of smokers receiving varenicline peaked at 2.1% among those with no mental illness, 2.9% among those with any mental illness, and 2.4% among those with serious mental illness. The respective peak proportions for NRT were 0.4%, 1.1%, and 1.6%; for bupropion, they were 1.2%, 8.4%, and 16.7%. Qualitative themes were consistent across general internists and psychiatrists; providers viewed cessation treatment as challenging because of the perception of smoking as a coping mechanism and agreed on barriers to treatment, including lack of insurance coverage and contraindications for people with mental illness. CONCLUSIONS System- and provider-level strategies to support evidence-based smoking cessation treatment for people with and without mental illness are needed.

Abstract
BACKGROUND Smoking cessation rates after stroke and transient ischemic attack are suboptimal, and smoking cessation interventions are underutilized. We performed a cost-effectiveness analysis of smoking cessation interventions in this population. METHODS We constructed a decision tree and used Markov models that aimed to assess the cost-effectiveness of varenicline, any pharmacotherapy with intensive counseling, and monetary incentives, compared with brief counseling alone in the secondary stroke prevention setting. Payer and societal costs of interventions and outcomes were modeled. The outcomes were recurrent stroke, myocardial infarction, and death using a lifetime horizon. Estimates and variance for the base case (35% cessation), costs and effectiveness of interventions, and outcome rates were imputed from the stroke literature. We calculated incremental cost-effectiveness ratios and incremental net monetary benefits. An intervention was considered cost-effective if the incremental cost-effectiveness ratio was less than the willingness-to-pay threshold of $100 000 per quality-adjusted life-year (QALY) or when the incremental net monetary benefit was positive. Probabilistic Monte Carlo simulations modeled the impact of parameter uncertainty. RESULTS From the payer perspective, varenicline and pharmacotherapy with intensive counseling were associated with more QALYs (0.67 and 1.00, respectively) at less total lifetime costs compared with brief counseling alone. Monetary incentives were associated with 0.71 more QALYs at an additional cost of $120 compared with brief counseling alone, yielding an incremental cost-effectiveness ratio of $168/QALY. From the societal perspective, all 3 interventions provided more QALYs at less total costs compared with brief counseling alone. In 10 000 Monte Carlo simulations, all 3 smoking cessation interventions were cost-effective in >89% of runs. CONCLUSIONS For secondary stroke prevention, it is cost-effective and potentially cost-saving to deliver smoking cessation therapy beyond brief counseling alone.

Abstract
BACKGROUND Most adult daily smokers try their first cigarette during adolescence. Attention-Deficit Hyperactivity Disorder (ADHD) in adolescents is associated with increased risk for cigarette smoking. The impact of ADHD symptoms on smoking cessation among adolescents has been less well-studied. The present secondary data analysis from a clinical trial of varenicline examined ADHD symptoms as a moderator of smoking cessation in adolescents and young adults. METHODS The double-blind, placebo-controlled trial included treatment-seeking daily cigarette smokers ages 14 - 21 (N = 157) randomized to receive a 12-week course of varenicline or placebo, added to weekly smoking cessation counseling. At pre-treatment assessment, participants were administered a self-report measure of ADHD symptoms, the ADHD - Rating Scale (ADHD-RS). High (≥5) versus low (<5) and continuous ADHD-RS symptom counts in both hyperactive/impulsive (HI) and inattention (IA) domains were examined as predictors of smoking outcomes. RESULTS Participants with high IA symptoms at baseline were less likely to achieve 7-day point prevalence abstinence (PPA) at weekly visits (p = .001) during active treatment and end-of-treatment (p = .002) compared to those with low IA symptoms. In contrast, high HI symptoms did not predict differences in 7-day PPA or end-of-treatment abstinence versus low symptoms (p's ≥ .07). These findings were not modified by varenicline versus placebo treatment assignment. CONCLUSIONS ADHD IA symptoms were associated with poorer cessation outcomes among adolescent smokers. These findings warrant additional investigation into how ADHD symptoms may be accounted for in smoking cessation interventions for adolescents and young adults.

Abstract
BACKGROUND Although varenicline has been used for alcohol dependence (AD) treatment, its efficacy for this condition remains controversial. AIMS This systematic review and meta-analysis of randomized controlled trials (RCTs) assesses the efficacy and safety of varenicline in patients with AD. METHODS PubMed, Cochrane Library, ScienceDirect, Web of Science, and ThaiLis were systematically searched. RCTs investigating the efficacy and safety of varenicline in patients with AD were included. Study selection, data extraction, and quality assessment were independently performed by two authors. The Jadad score and Cochrane risk of bias were used to assess the quality of the included studies. Heterogeneity was assessed using I2 and chi-squared tests. RESULTS Twenty-two high-quality RCTs on 1421 participants were included. Varenicline significantly reduced alcohol-related outcomes compared with placebo based on percentage of abstinent days (standardized mean difference [SMD] 4.20 days; 95% confidence interval [CI]: 0.21, 8.19; p = 0.04), drinks per day (SMD -0.23 drinks; 95% CI: -0.43, -0.04; p = 0.02), drinks per drinking day (SMD -0.24 drinks; 95% CI: -0.44, -0.05; p = 0.01), craving assessed using the Penn alcohol craving scale (SMD -0.35; 95% CI: -0.59, -0.12; p = 0.003), and craving assessed using the alcohol urge questionnaire (SMD -1.41; 95% CI: -2.12, -0.71; p < 0.0001). However, there were no significant effects on abstinence rate, percentage of drinking days, percentage of heavy drinking days, alcohol intoxication, or drug compliance. Serious side effects were not observed in the varenicline or placebo groups. CONCLUSION Our results indicated that AD patients treated with varenicline showed improvement in percentage of very heavy drinking days, percentage of abstinent days, drinks per day, drinks per drinking day, and craving. However, well-designed RCTs with a large sample size and long duration on varenicline treatment in AD remain warranted to confirm our findings.

Abstract
BACKGROUND Waterpipe smoking is increasing worldwide with no proven interventions for cessation. We compared abstinence rates with 12-week varenicline therapy versus placebo among habitual waterpipe smokers willing to quit. METHODS This double-blind placebo-controlled single-center trial, randomized waterpipe smokers from Lebanon who did not smoke other tobacco products to receive varenicline or placebo for 12 weeks. All participants also received three structured 30-minute individual behavioral intervention sessions. The primary outcome was repeated point prevalence abstinence assessed by self-report and verified by exhaled carbon monoxide three times during 12 weeks and analyzed with the intention to treat. End of treatment urine cotinine, weight, blood pressure, anxiety, depression, withdrawal, and adverse symptoms were also assessed. RESULTS In total, 152 waterpipe smokers (mean age 38 years [SD = 13], 39% females) willing to quit, who smoked waterpipe exclusively (average 2.3 per day [SD = 1.6] for 16.8 years [SD = 10.8]) were randomized. Seventy-nine participants (52%) with any missing abstinence assessment were considered to have relapsed. Repeat point prevalence abstinence rate was numerically higher among the varenicline group compared to placebo, but the difference did not reach statistical significance when assessed by self-report (16.9 vs. 13.6%, respectively, p = .6) and when further verified by exhaled carbon monoxide (14.1% vs. 9.9%, respectively, p = .4). Abstinence rates were similar in both groups when further verified by urine cotinine at end of treatment. No serious adverse events were reported, adverse symptoms and other outcomes were similar in the varenicline and placebo arms. CONCLUSIONS Varenicline for 12 weeks was not more effective than placebo to achieve abstinence among daily waterpipe smokers. IMPLICATIONS Varenicline in combination with a behavioral intervention did not significantly enhance the quit rate among exclusive waterpipe smokers compared to behavioral intervention plus placebo. We experienced difficulty enrolling exclusive waterpipe smokers willing to quit and observed high dropout rates among participants demonstrating the difficulties of waterpipe smoking cessation.

Abstract
Dozens of drugs have been evaluated in recent decades for initial evidence of efficacy to aid smoking cessation (i.e. "early Phase 2" testing, according to U.S. FDA terminology), with the vast majority failing to show efficacy. Even small randomized clinical trials (RCTs), the most common early Phase 2 tests, are costly undertakings, made more unappealing by their high likelihood of failure. At the same time, another early Phase 2 approach, acute tests of drug effects on surrogate endpoints such as withdrawal or craving severity, are more practical but have little predictive clinical validity. Described here is an innovative procedure that optimally combines the validity of clinical trials with the practical advantages of surrogate endpoint studies to more efficiently determine whether or not a novel drug warrants continued clinical development. This CrEATE procedure, or Crossover Evaluation of Addiction Treatment Efficacy, does so by assessing short-term quit success in smokers highly motivated to quit when briefly treated with active drug versus placebo in a crossover design, so that quit efficacy from both conditions is compared within participants. The program to develop and evaluate CrEATE demonstrates its sensitivity to efficacy from all three FDA-approved first-line cessation medications (NRT, varenicline, bupropion), tested here as model drugs, as well as specificity in identifying lack of efficacy with a drug known to be ineffective for cessation (modafinil). CrEATE has subsequently been used to evaluate a few novel interventions, concluding they lack efficacy in increasing quit success. Future directions for the potential utility of CrEATE are provided. Implications: The ability of CrEATE to reach a Go/No Go decision more quickly and with far less cost lowers the risk of failure, meaning widespread use of the procedure should encourage the evaluation of more novel candidate drugs. With its greater efficiency, failed tests, unfortunately the most likely outcome in early Phase 2 studies, will cause less waste of resources. At the same time, CrEATE tests that indicate a novel treatment has efficacy will justify the substantial time and expense of moving forward to evaluate the drug in late Phase 2 RCTs.

Abstract
BACKGROUND Behavioral treatments can augment the success of pharmacotherapy in smoking cessation. The aim of this study was to compare smoking quit rates between patients receiving individual counseling with their general practitioner during office visits or intensive counselling with behavioral support, both augmented by varenicline. METHODS A nationwide retrospective cohort study conducted in a large Healthcare Maintenance Organization in Israel. We selected randomly patients who filled a prescription for varenicline and received either individual consulting by their general practitioner or intensive counselling with behavioural support, and asked them to answer a questionnaire. The outcome variables were smoking cessation 26-52 weeks following the beginning of treatment and satisfaction with the process. RESULTS 870 patients were contacted and 604 agreed to participate (a response rate of 69%); 301 patients in the general practitioner group, 300 in the intensive counselling group and 3 were excluded due to missing date. The quit rate was 36.5% in the general practitioner group and 42.3% in the intensive counselling group (P = 0.147). In a logistic regression analysis, controlling for age, gender, socioeconomic status, ischemic heart disease, chronic obstructive pulmonary disease, pack years and duration of varenicline consumption, the adjusted OR for quitting in the general practitioner group was 0.79 (95% CI 0.56,1.13). The adjusted OR was higher in the group with the highest socioeconomic status at 2.06 (1.39,3.07) and a longer period of varenicline consumption at 1.30 (1.15,1.47). Age, gender and cigarette pack-years were not associated with quit rate. In the general practitioner group 68% were satisfied with the process, while 19% were not. In the intensive counselling group 64% were satisfied and 14% were not (P = 0.007). CONCLUSION We did not detect a statistically significant difference in smoking quit rates, though there was a trend towards higher quit rates with intensive counselling.

Abstract
Use of varenicline in a quit attempt was associated with increased odds of smoking cessation. Data were inconclusive regarding a benefit of e-cigarettes for smoking cessation. Use of e-cigarettes was unlikely associated with lower odds of smoking cessation. Associations between other aids and cessation were inconclusive.
Objective To examine the real-world effectiveness of popular smoking cessation aids, adjusting for potential confounders measured up to 12 months before the quit attempt. Methods 1,045 adult (≥18y) smokers in England provided data at baseline (April 2015-November 2020) and reported a serious past-year quit attempt at 12-month follow-up. Our outcome was smoking cessation, defined as self-reported abstinence at 12 months. Independent variables were use in the most recent quit attempt of: varenicline, prescription NRT, over-the-counter NRT, e-cigarettes, and traditional behavioural support. Potential confounders were age, sex, social grade, alcohol consumption, and level of dependence (measured at baseline), variables relating to the most recent quit attempt (measured at 12-month follow-up), and survey year. Results Participants who reported using varenicline in their most recent quit attempt had significantly higher odds of abstinence than those who did not, after adjustment for potential confounders and use of other aids (OR = 2.69, 95 %CI = 1.43–5.05). Data were inconclusive regarding whether using prescription NRT, over-the-counter NRT, e-cigarettes, or traditional behavioural support was associated with increased odds of abstinence (p > 0.05; Bayes factors = 0.41–1.71, expected effect size OR = 1.19), but provided moderate evidence that using e-cigarettes was more likely associated with no effect than reduced odds (Bayes factor = 0.31, expected effect size OR = 0.75). Conclusions Use of varenicline in a quit attempt was associated with increased odds of successful smoking cessation. Data were inconclusive regarding a benefit of e-cigarettes for cessation but showed use of e-cigarettes was unlikely to be associated with reduced odds of cessation. Associations between other cessation aids and cessation were inconclusive.

Abstract
IMPORTANCE Even with varenicline, the leading monotherapy for tobacco dependence, smoking abstinence rates remain low. Preliminary evidence suggests that extending the duration of varenicline treatment before quitting may increase abstinence. OBJECTIVE To test the hypotheses that, compared with standard run-in varenicline treatment (1 week before quitting), extended run-in varenicline treatment (4 weeks before quitting) reduces smoking exposure before the target quit date (TQD) and enhances abstinence, particularly among women. DESIGN, SETTING, AND PARTICIPANTS This double-blind, randomized, placebo-controlled clinical trial enrolled participants from October 2, 2017, to December 9, 2020, at a single-site research clinic in Buffalo, New York. Of 1385 people screened, 320 adults reporting smoking 5 or more cigarettes per day (CPD) were randomized and followed up for 28 weeks. Data were analyzed from August 2021 to June 2022. INTERVENTIONS In the pre-TQD period (weeks 1-4), the extended run-in group received 4 weeks of varenicline; the standard run-in group received 3 weeks of placebo followed by 1 week of varenicline. Both groups received open-label varenicline during weeks 5 to 15 and brief quit counseling at 6 clinic visits. MAIN OUTCOMES AND MEASURES The primary outcome consisted of cotinine-verified (at end of treatment [EOT]) self-reported continuous abstinence from smoking (in CPD) during the last 4 weeks of treatment. Secondary outcomes included bioverified self-report of continuous abstinence at the 6-month follow-up and percentage of reduction in self-reported smoking rate during the prequit period (week 1 vs week 4). RESULTS A total of 320 participants were randomized, including 179 women (55.9%) and 141 men (44.1%), with a mean (SD) age of 53.7 (10.1) years. Continuous abstinence during the final 4 weeks of treatment (weeks 12-15; EOT) was not greater in the extended run-in group (64 of 163 [39.3%]) compared with the standard run-in group (57 of 157 [36.3%]; odds ratio [OR], 1.13 [95% CI, 0.72-1.78]), nor was the hypothesized group × sex interaction significant (OR, 0.52 [95% CI, 0.21-1.28]). Similar nonsignificant results were obtained for continuous abstinence at the 6-month follow-up. The mean (SE) decrease in self-reported smoking rate during the prequit period was greater in the extended run-in group (-38.8% [2.8%]) compared with the standard run-in group (-17.5% [2.7%]). CONCLUSIONS AND RELEVANCE Among adult daily smokers, extending the duration of prequit varenicline treatment beyond the standard 1-week run-in period reduced prequit smoking exposure but, more importantly, did not significantly improve continuous abstinence rates.

Abstract
BACKGROUND Cytisine is a prospective pharmacological alternative for community pharmacy smoking cessation services. However, it has not yet been licensed because of a lack of efficacy and safety information in Thailand. OBJECTIVE The aim of this study was to evaluate the efficacy of cytisine in combination with community pharmacists' counselling on smoking cessation in a community pharmacy in ThailandDesign. Setting, participants, and interventions: A double-blinded randomized placebo-controlled trials was carried out. Participants aged >18 years old who smoked >10 tobaccos/day were randomly assigned to receive cytisine or placebo and five sessions of counselling by a community pharmacist. The primary outcome was a continuous abstinence rate (CAR) at week 48. The CAR was also measured at weeks 2, 4, 12, and 24. Adverse events were monitored. RESULTS A total of 132 participants were included, with 67 receiving cytisine and 65 receiving a placebo. Approximately 95% of participants were male. The CARs were determined to be 14.93% and 6.15% for cytisine and placebo, respectively, at week 48. The relative risk (RR) was 2.41 (95% confidence interval (CI); 0.80-7.35, p = 0.102). The RRs for CAR at weeks 2, 4, 12, and 24 were 2.43, 2.91, 2.50, and 1.78, respectively. Only the RRs for weeks 2, 4, and 12 were statistically significant. Common and non-serious gastrointestinal and neurological adverse events were observed. CONCLUSION Cytisine, when combined with community pharmacists' counselling, did not statistically improve the CAR at week 48, although it did improve the CAR at weeks 2, 4, and 12. Adverse events of cytisine were common and non-serious (registration number: TCTR20180312001).

Abstract
People with HIV (PWH) have higher rates of tobacco use compared to their societal counterparts and are disproportionately affected by tobacco-related morbidity and mortality. A needs assessment was conducted to assess provider beliefs and opinions on tobacco treatment barriers and treatment approaches. The results highlighted a disconnect between the known importance of quitting smoking and barriers in linking patients to treatment, such as lack of patient interest and other patient issues being a higher priority. Using this assessment data, a treatment delivery approach, Proactive Outreach with Medication Opt-out for Tobacco Treatment Engagement (PrOMOTE), was devised and piloted. PrOMOTE consisted of an outpatient clinical pharmacist trained in tobacco treatment proactively contacting patients for counseling and to prescribe smoking cessation pharmacotherapy (varenicline or dual nicotine replacement therapy (NRT)) using an opt-out approach. The pilot was conducted with 10 PWH and patient reach and opt-out rates were evaluated. Of the 10 patients contacted, 7 were reached and none opted out of the pharmacotherapy prescription (varenicline = 6; NRT = 1). Providers know the importance of smoking cessation for PWH but encounter several barriers to implementing treatment. Using PrOMOTE methods to deliver tobacco treatment increased the reach and pharmacotherapy acceptance rate of PWH who smoke.

Abstract
PURPOSE The purpose of this trial was to evaluate the safety and efficacy of OC-01 (varenicline solution), a nicotinic acetylcholine receptor agonist nasal spray, on signs and symptoms of dry eye disease. METHODS A phase 2b, multicenter, randomized, double-masked, vehicle-controlled trial (ONSET-1; NCT03636061) was performed. Patients were aged 22 years or older with a physician's diagnosis of dry eye disease and previous use of artificial tears were randomized 1:1:1:1 to control (vehicle nasal spray twice daily [BID]), OC-01 0.006 mg BID, OC-01 0.03 mg BID, and OC-01 0.06 mg BID. The primary end point was the change in the anesthetized Schirmer test score from baseline to day 28 in the study eye. The secondary end points included the change in the eye dryness score from baseline to day 28. RESULTS One hundred eighty-two patients were randomized. After 28 days, patients who received OC-01 0.03 or 0.06 mg showed a statistically significant improvement in tear film production relative to vehicle, with least squares mean differences from vehicle of 7.7 mm [95% confidence interval, 3.8-11.7; P < 0.001] with OC-01 0.03 mg and 7.5 mm (95% confidence interval, 3.4-11.6; P < 0.001) with OC-01 0.06 mg. Patients receiving OC-01 0.03 mg showed a significant reduction in the eye dryness score by day 28 versus vehicle (P = 0.021); those receiving the OC-01 0.06 mg dose showed a nonsignificant reduction versus vehicle. OC-01 administration was associated with sneezing (62%-84%) and cough (9%-25%); these were transient and predominantly mild in severity. CONCLUSIONS OC-01 nasal spray administered BID at 0.03 and 0.06 mg resulted in significant improvements in signs and symptoms of dry eye disease, was well tolerated, and warrants further clinical investigation.

Abstract
OBJECTIVE A network meta-analysis (NMA) was conducted to investigate the effect of varenicline (VAR), bupropion (BUP), and nicotine replacement therapy (NRT) on smoking cessation. METHODS Eight databases were searched in May 2021, and only randomized controlled trials (RCTs) using varenicline, bupropion, or NRT (single or combined) for smoking cessation were included. The risk of bias in the included RCTs was assessed using the Cochrane Handbook tool. Stata 15.1 software was used to perform NMA, and the quality of the evidence was evaluated using Confidence in Network Meta-analysis (CINeMA). FINDINGS Twenty RCTs involving 16,702 smokers were included. The risk of bias results showed that 10 RCTs were rated as high, three were low, and seven were unclear. A total of 21 pairs were compared based on seven interventions. The NMA showed that, compared to the placebo (PLA), the other six interventions had significant efficacy in smoking cessation, where VAR + BUP showed the best effect of all treatments (odds ratio (OR) = 6.08, 95% confidence interval (CI) [3.47, 10.66]). Moreover, VAR + BUP was superior to VAR + NRT (OR = 1.66, 95% CI [1.07, 2.59]) and the three monotherapies (VAR, BUP, and NRT). In the monotherapies, the results of pairwise comparisons of VAR, BUP, and NRT did not show significant differences. Finally, the surface under the cumulative ranking curve (SUCRA) value indicated that VAR + BUP had the greatest probability of becoming the best intervention. CONCLUSIONS The efficacy of VAR, BUP, and NRT alone increased the odds of smoking abstinence better than the placebo, combined interventions were superior to monotherapy, and VAR combined with other interventions had a better smoking cessation effect.

Abstract
IMPORTANCE Cigarette smoking and risky alcohol consumption co-occur and are undertreated. Nicotine receptor partial agonists and nicotine replacement therapy (NRT) treat smoking but are unproven for alcohol, and clinical trials rarely include individuals with HIV, substance use, and mental health conditions. OBJECTIVE To compare the effects on drinking and smoking of nicotinic acetylcholine receptor partial agonists varenicline and cytisine with those of NRT. DESIGN, SETTING, AND PARTICIPANTS This 4-group randomized, double-blinded, placebo-controlled clinical trial was conducted from July 2017 to December 2020 in St Petersburg, Russia. Included participants were 400 individuals with HIV who engaged in risky drinking (≥5 prior-month heavy-drinking days [HDDs]) and daily smoking; they were followed up for 12 months after enrollment. Data were analyzed from May 2021 through June 2022. INTERVENTIONS Participants received alcohol and tobacco counseling, 1 active medication, and 1 placebo in 1 of 4 groups: active varenicline and placebo NRT (group 1), placebo varenicline and active NRT (group 2), active cytisine and placebo NRT (group 3), or placebo cytisine and active NRT (group 4). MAIN OUTCOMES AND MEASURES The primary outcome was number of prior-month HDDs at 3 months. Secondary outcomes included biochemically validated abstinence from alcohol at 3 months and smoking at 6 months. RESULTS Among 400 participants (263 [65.8%] men; mean [SD] age, 39 [6] years), 97 individuals (24.3%) used opioids and 156 individuals (39.1%) had depressive symptoms. These individuals had a mean (SD) CD4 count of 391 (257) cells/mm3, smoked a mean (SD) of 21 [8] cigarettes/d, and reported a mean (SD) of 9.3 (5.8) HDDs in the prior 30 days. At 3 months, the mean (SD) number of HDDs was decreased vs baseline across all groups (group 1: 2.0 [3.8] HDDs vs. 9.5 [6.1] HDDs; group 2: 2.1 [4.3] HDDs vs 9.3 [5.7] HDDs; group 3: 1.5 [3.3] HDDs vs 8.9 [5.0] HDDs; group 4: 2.4 [5.2] HDDs vs 9.6 [6.3] HDDs). There were no significant differences at 3 months between groups in mean (SD) HDDs, including group 1 vs 2 (incident rate ratio [IRR], 0.94; 95% CI, 0.49-1.79), 3 vs 4 (IRR, 0.60; 95% CI, 0.30-1.18), and 1 vs 3 (IRR, 1.29; 95% CI, 0.65-2.55). There were no significant differences at 6 months between groups in smoking abstinence, including group 1 vs 2 (15 of 100 individuals [15.0%] vs 17 of 99 individuals [17.2%]; odds ratio [OR],0.89; 95% CI, 0.38-2.08), 3 vs 4 (19 of 100 individuals [19.0%] vs 19 of 101 individuals [18.8%]; OR, 1.00; 95% CI, 0.46-2.17), and 1 vs 3 (OR, 0.79; 95% CI, 0.35-1.78). Post hoc analyses suggested lower mean (SD) HDDs (eg, at 3 months: 0.7 [1.8] HDDs vs 2.3 [4.6] HDDs) and higher alcohol abstinence (eg, at 3 months: 30 of 85 individuals [35.3%] vs 54 of 315 individuals [17.1%]) among those who quit vs continued smoking. CONCLUSIONS AND RELEVANCE This study found that among individuals with HIV who engaged in risky drinking and smoking, varenicline and cytisine were not more efficacious than NRT to treat risky drinking and smoking but that behavior change rates were high in all groups. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT02797587.
