Abstract
Background The effectiveness of long-acting injectable (LAI) antipsychotics in preventing relapses of first-episode psychosis is currently debated. Objectives The study aimed to investigate the number of psychiatric hospitalizations comparing the LAI cohort versus the oral cohort during different phases of the illness, pre-LAI treatment, during LAI treatment, and after LAI treatment. Design A naturalistic study was conducted on two independent cohorts of early psychosis patients receiving treatment from a specific early intervention service. The first cohort comprised 228 patients who received LAIs, while the second cohort comprised 667 patients who had never received LAIs. Methods This study was designed as a longitudinal observational study conducted within a naturalistic clinical setting in two cohorts of early psychosis patients. Repeated series ANCOVA (ANCOVA-r) was used to study the number of hospitalizations in the different study periods (T1 = from the date of the first psychiatric record to the beginning of the mirror period; T2 = the mirror period; T3 = from the LAI implementation to the LAI discontinuation; and T4 = from the LAI discontinuation to the end). In all cases, discontinuation of LAI involved the return to oral treatment. In all, 35 patients had not T4 as they were still on LAI treatment at the time of database closing (September 2020), and their data were not included in the analysis of the effect of the LAI discontinuation. Results The patients in the LAI cohort were younger, more frequently males, presented more schizophrenia diagnoses, and had a higher number of hospitalizations (2.50 ± 2.61 versus 1.19 ± 1.69; p < 0.001) than the oral cohort. The number of hospitalizations at the end of the follow-up was higher in the LAI cohort [0.20 (standard deviation (SD)) = 0.79] versus 0.45 [SD = 0.45 (SD = 1.13); F(23.90), p < 0.001]. However, after the introduction of LAIs, the differences in hospitalization rates between the two cohorts became less pronounced. Once LAI treatment was ceased, the hospitalization rate increased again. Conclusion In our study, early psychosis patients receiving LAIs experienced a greater decrease in hospitalizations after introducing the LAI treatment than those treated solely with oral medication. These findings support using LAIs as a viable strategy for preventing rehospitalization and improving the overall course of treatment for individuals with early psychosis.

Abstract
ABSTRACTInjectable antiretroviral treatment (ART) represents a new effective and potentially more convenient alternative to oral ART for people living with HIV (PLWH). This study assessed preferences of PLWH for long-acting injectable compared with oral ART in the Netherlands. A labelled discrete choice experiment presented 12 choice sets of long-acting injectable and oral ART. PLWH were asked to select their preferred ART, described by six attributes: location of administration, dosing frequency, risk of short-term side effects, drug-drug interaction, forgivability, and food and mealtime restrictions. Random parameters logit and latent class models were used to estimate preferences of PLWH. 98.6% of 76 respondents were experienced oral ART users that had taken ART for a median of 12 years (Q1-Q3: 7.0-20.0). 30 (39.5%) respondents chose long-acting injectable ART in all choice tasks and 22 (28.9%) always chose oral ART. The random parameter model showed that, on average, respondents significantly favoured long-acting injectable ART over oral ART, preferred administration of the long-acting injectable ART at home, and a less frequent regimen. The latent class model confirmed one class strongly preferring long-acting injectable ART and one class slightly preferring oral ART. This study highlights the value for both long-acting injectable and oral ART.

Abstract
BACKGROUND HIV pre-exposure prophylaxis (PrEP) is a highly effective method to mitigate the HIV epidemic, but uptake of PrEP has been slow and is associated with racial and gender disparities. Oral PrEP requires high levels of adherence to be effective, which may disadvantage certain high-risk groups. The first injectable HIV PrEP, a drug given every 2 months rather than as a daily pill, was approved by the US Food & Drug Administration in December 2021. SETTING A Family Medicine practice in a single health organization in the United States (November 2022 to February 2023). METHODS We conducted interviews with patients and key stakeholders to characterize factors affecting long-acting injectable (LAI) PrEP implementation. Data collection and analysis were guided by the Consolidated Framework for Implementation Research. Interviews were transcribed and analyzed using guided content analysis. RESULTS Twenty-five patients (n = 13) and practice stakeholders (n = 12) were interviewed. Overall, stakeholders described a very low uptake of LAI PrEP. Barriers to LAI PrEP included a lack of awareness, insurance and access issues, a lack of streamlined workflow, and a trust in pills over injectables. Facilitators to LAI PrEP implementation included the absence of a pill burden, a culture of shared decision making, and pharmacy support. CONCLUSIONS Although uptake has been slow, we have identified several promising strategies for improving rollout and implementation of LAI PrEP. Approaches that can bolster rollout of LAI PrEP include having an interdisciplinary care team that is supported by PrEP navigators and pharmacists and are informed by a patient-centered model of care to increase patient engagement and trust.

Abstract
Long-acting cabotegravir/rilpivirine (LA-CAB/RPV) is the first complete injectable antiretroviral for patients living with HIV. To facilitate patient access to long-acting injectable treatment, a system-wide, pharmacist-led, LA-CAB/RPV transition program was developed at four health system-based New York clinics. Provider referrals were received across four clinics between January 22nd, 2021, and December 31st, 2022. All referrals were evaluated by a pharmacist for clinical eligibility and medication access. The primary outcome was the treatment retention rate defined as the percentage of patients who remained on LA-CAB/RPV at 3 months post-transition. A total of 171 referrals were received, with 73 patients (43%) initiating LA-CAB/RPV. Baseline demographics included a median age of 38 years, 81% patients were male, 41% were African American, and 49% had commercial insurance coverage. The treatment retention rate was 90% at 3 months post-transition. By the end of the study period, 84% of patients who transitioned remained on LA-CAB/RPV. Treatment was discontinued due to reasons such as viral breakthrough (4%), emergence of mutations (4%), and intolerable side effects (4%). Injection site reactions were commonly reported (51%), but only resulting in treatment discontinuation for one patient. A pharmacist-led program can transition a diverse population of patients living with HIV to LA-CAB/RPV. Results from this study further add to clinical experiences with LA-CAB/RPV, demonstrating real-world treatment retention despite more frequent clinic visits for patients.

Abstract
OBJECTIVE To review the efficacy, safety, and role of lenacapavir (LEN) in the treatment of HIV-1 infection. DATA SOURCES A literature search was performed using PubMed and Google Scholar (through March 2023) with the search term LEN and GS-6207. Other resources included abstracts presented at recent conferences, the manufacturer's Web site, and prescribing information. STUDY SELECTION AND DATA EXTRACTION All relevant articles, trial updates, and conference abstracts in the English language were included. DATA SYNTHESIS Lenacapavir represents a new class of antiretrovirals (ARVs) with a novel mechanism of action as a capsid inhibitor and a unique twice-a-year subcutaneous administration schedule. Lenacapavir when combined with other ARVs has proven to benefit heavily treatment-experienced (HTE) patients with HIV-1 infection in achieving viral suppression and immune restoration. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE IN COMPARISON WITH EXISTING DRUGS Lenacapavir is a new treatment option that patients who are HTE can consider adding as part of an ARV regimen. CONCLUSIONS Lenacapavir is an effective and well-tolerated option for HTE patients which is a valuable addition to the arsenal of ARVs.

Abstract
Single-stranded antisense oligonucleotides (ASOs) are typically administered subcutaneously once per week or monthly. Less frequent dosing would have strong potential to improve patient convenience and increase adherence and thereby for some diseases result in more optimal therapeutic outcomes. Several technologies are available to provide sustained drug release via subcutaneous (SC) administration. ASOs have a high aqueous solubility and require relatively high doses, which limits the options available substantially. In the present work, we show that an innovative biodegradable, nonporous silica-based matrix provides zero-order release in vivo (rats) for at least 4 weeks for compositions with ASO loads of up to about 100 mg/mL (0.5 mL injection) without any sign of initial burst. This implies that administration beyond once monthly can be feasible. For higher drug loads, substantial burst release was observed during the first week. The concentrations of unconjugated ASO levels in the liver were found to be comparable to corresponding bolus doses. Additionally, infusion using a minipump shows a higher liver exposure than SC bolus administration at the same dose level and, in addition, clear mRNA knockdown and circulating protein reduction comparable to SC bolus dosing, hence suggesting productive liver uptake for a slow-release administration.

Abstract
BACKGROUND We evaluated the impact of the CHORUS™ app on adherence to the cabotegravir and rilpivirine long-acting injectable (CAB + RPV LAI) monthly injections schedule. METHODS Healthcare centers (HCCs) were randomized to access CHORUS™ CAB + RPV LAI features (intervention) or not (control) from 01OCT2021-31JAN2022. Target window adherence (maintenance injections ≤7 days before/after target day) was assessed with multivariate logistic regression (generalized estimating equations). RESULTS CAB + RPV LAI was administered to 188 and 79 individuals at intervention and control HCCs, respectively. Intervention was not associated with improved target window adherence (adjusted odds ratio: 0.61 [95% CI: 0.30-1.25]). However, app use was associated with increased odds of adherence compared to no app use among all intervention HCCs (2.98 [1.26-7.06]) and at smaller HCCs (3.58 [1.31-9.80]). CONCLUSIONS While access to CHORUS™ CAB + RPV LAI features did not improve target window adherence, app use did, especially at smaller HCCs which may not have established LAI management procedures.

Abstract
Background Little is known about the preferences for antiretroviral therapy (ART) administration methods, such as oral daily pills or long-acting injectable (LAI) options, as well as preferences for pre-exposure prophylaxis (PrEP) administration methods among people without HIV in Latin America. Objectives This study aimed to assess the preferences for ART administration methods among people with HIV and PrEP methods among those without HIV, as well as to examine the correlations and reasons for these preferences. Design We conducted a cross-sectional web-based questionnaire between April and July 2021, using social media accounts of a HIV non-governmental organization. The questionnaire was open to all adults living in Argentina, irrespective of their sexual orientation or gender identity. Methods The questionnaire included questions on substance use, depression, chronic treatment, previous experiences with injectable medication, and HIV status. Those with HIV answered questions about ART adherence and their preferences for ART methods, while those without HIV were asked about condom use, awareness of PrEP, and their preferences for PrEP methods. Results Out of 1676 respondents, 804 had HIV, and 872 did not. Among those with HIV, 91.5% expressed a high preference for LAI-ART, with significantly higher preferences among participants with higher educational levels, cisgender gay, bisexual, and queer men, younger individuals, and those with prior injectable medication experience. Among those without HIV, 68% preferred LAI-PrEP, and this preference was positively associated with previous positive experiences with injectable medication. Conclusion The strong preference for LAI-ART suggests the potential for improved adherence and well-being among people with HIV. Additionally, the preference for LAI-PrEP among those without HIV emphasizes the importance of considering this option for HIV prevention strategies. This study highlights the need to offer diverse methods for ART and prevention to accommodate different preferences and improve health care outcomes in Latin America.

Abstract
This paper presents the in vitro and in vivo degradation of BEPO, a marketed in situ forming depot technology used for the formulation of long-acting injectables. BEPO is composed of a solution of a blend of poly(ethylene glycol)-block-poly(lactic acid) (PEG-PLA) triblock and diblock in an organic solvent, where a therapeutic agent may be dissolved or suspended. Upon contact with an aqueous environment, the solvent diffuses and the polymers precipitate, entrapping the drug and forming a reservoir. Two representative BEPO compositions were subjected to a 3-month degradation study in vitro by immersion in phosphate-buffered saline at 37 °C and in vivo after subcutaneous injection in minipig. The material erosion rate, as a surrogate of the bioresorption, determined via the depot weight loss, changed substantially, depending on the composition and content of polymers within the test item. The swelling properties and internal morphology of depots were shown to be highly dependent on the solvent exchange rate during the precipitation step. Thermal analyses displayed an increase of the depot glass transition temperature over the degradation process, with no crystallinity observed at any stage. The chemical composition of degraded depots was determined by 1H NMR and gel permeation chromatography and demonstrated an enrichment in homopolymers, i.e., free PLA and (m)PEG, to the detriment of (m)PEG-PLA copolymers in both formulations. It was observed that the relative ratio of the degradants within the depot is driven by the initial polymer composition. Interestingly, in vitro and in vivo results showed very good qualitative consistency. Taken together, the outcomes from this study demonstrate that the different hydrolytic degradation behaviors of the BEPO compositions can be tuned by adjusting the polymer composition of the formulation.

All English-language articles describing clinical trials assessing the efficacy and safety of lenacapavir when used in humans for the treatment of HIV infection were included. Review articles, conference abstracts, and article references were evaluated for relevant information, and data were also obtained from the manufacturer's website and the package insert. Lenacapavir has been approved by the Food and Drug Administration (FDA) for the treatment of HIV-1 infection in heavily treatment-experienced adults with multidrug resistance for whom the current antiretroviral regimen is failing due to resistance, intolerance, or safety considerations. It is the first in a new class of drugs called capsid inhibitors to receive FDA approval. Lenacapavir is a long-acting subcutaneous injectable to be administered once every 6 months. The phase 3 clinical trial evaluating lenacapavir has demonstrated its efficacy in viral load reduction from baseline compared to placebo in patients receiving optimized background therapy. The most common adverse events reported in the clinical trial were injection site reactions, occurring in 63% of participants. CONCLUSION Lenacapavir is a novel capsid inhibitor indicated, in combination with other antiretroviral therapy, for treatment of multidrug-resistant HIV-1 infection.

Abstract
Lenacapavir (LEN) is a picomolar first-in-class capsid inhibitor of human immunodeficiency virus type 1 (HIV-1) with a multistage mechanism of action and no known cross resistance to other existing antiretroviral (ARV) drug classes. LEN exhibits a low aqueous solubility and exceptionally low systemic clearance following intravenous (IV) administration in nonclinical species and humans. LEN formulated in an aqueous suspension or a PEG/water solution formulation showed sustained plasma exposure levels with no unintended rapid drug release following subcutaneous (SC) administration to rats and dogs. A high total fraction dose release was observed with both formulations. The long-acting pharmacokinetics (PK) were recapitulated in humans following SC administration of both formulations. The SC PK profiles displayed two-phase absorption kinetics in both animals and humans with an initial fast-release absorption phase, followed by a slow-release absorption phase. Noncompartmental and compartmental analyses informed the LEN systemic input rate from the SC depot and exit rate from the body. Modeling-enabled deconvolution of the input rates from two processes: absorption of the soluble fraction (minor) from a direct fast-release process leading to the early PK phase and absorption of the precipitated fraction (major) from an indirect slow-release process leading to the later PK phase. LEN SC PK showed flip-flop kinetics due to the input rate being substantially slower than the systemic exit rate. LEN input rates via the slow-release process in humans were slower than those in both rats and dogs. Overall, the combination of high potency, exceptional stability, and optimal release rate from the injection depot make LEN well suited for a parenteral long-acting formulation that can be administered once up to every 6 months in humans for the prevention and treatment of HIV-1.

Abstract
OBJECTIVE The aim is to assess the impact of long-acting buprenorphine (LAI-BNP) on frequency of methamphetamine (MA) use. METHODS We undertook an observational, descriptive, retrospective cohort study of patients of a public, tertiary, community-based Alcohol and Other Drug Service (AODS) with opioid use disorder (OUD) treated with LAI-BNP who are current or past users of MA. We assessed the changes of frequency of use in their MA use at start (baseline), 3 and 6 months of LAI-BNP. RESULTS Study included 59 participants. Based on their MA use at the commencement of LAI-BNP, the sample was further sub-grouped as active users (n = 30) and past users (n = 29). At 6 months of LAI-BNP, all the past users remained abstinent from MA use. 70% (n = 21) of participants with active MA use had reduced or ceased their MA use while 17% (n = 5) increased their MA use at 6 months. CONCLUSIONS The results favour the use of LAI-BNP as a potential treatment for MA use.

Abstract
Background The paliperidone palmitate 6-month (PP6M) long-acting injectable formulation is currently the longest dosing interval available for schizophrenia treatment. Objective To compare treatment outcomes between a real-world external comparator arm (ECA; NeuroBlu database) and the PP6M open-label extension (OLE) clinical trial arm. Methods The ECA comprised patients receiving PP 1-month (PP1M) or PP 3-month (PP3M) for ⩾12 months without a relapse. The PP6M OLE arm included patients with PP1M treatment prior to randomization who completed the 12-month double-blind PP6M study on either PP3M or PP6M relapse-free. Inverse probability treatment weighting (IPTW) was used to study time-to-relapse (primary outcome) and change in Clinical Global Impressions-Severity (CGI-S) score (secondary outcome). Results At 24 months, 3.9% (7/178) of patients in the PP6M cohort experienced a relapse versus 15.6% (26/167) in the ECA. Time-to-relapse was longer in the PP6M cohort versus the ECA at 12-, 18-, and 24-months across the different weighting methods; median time-to-relapse was not reached in both cohorts. Hazard ratio (HR) for relapse was significantly lower for the PP6M cohort versus the ECA throughout the duration of the study [HR at 24 months: 0.18 (95% CI: 0.08-0.42), p < 0.001]. At 24 months, change in CGI-S score for the PP6M cohort was 0.76 points lower than the ECA (p < 0.001). Results were similar in a sensitivity analysis using propensity score matching (PSM); IPTW resulted in larger sample sizes in balanced dataset than PSM. Conclusion Consistent findings across weighting and matching methods suggest PP6M efficacy in reducing and delaying relapses and long-term symptom control compared to PP1M/PP3M in usual-care settings. Additional confounds, such as greater illness severity and more frequent comorbidities and comedications in the ECA, were not fully controlled by the applied statistical methods. Future real-world studies directly comparing PP6M with PP3M/PP1M and adjusting for these confounders are warranted.

Abstract
AIDS (acquired immunodeficiency syndrome) is a potentially life-threatening infectious disease caused by human immunodeficiency virus (HIV). To date, thousands of people have lost their lives annually due to HIV infection, and it continues to be a big public health issue globally. Since the discovery of the first drug, Zidovudine (AZT), a nucleoside reverse transcriptase inhibitor (NRTI), to date, 30 drugs have been approved by the FDA, primarily targeting reverse transcriptase, integrase, and/or protease enzymes. The majority of these drugs target the catalytic and allosteric sites of the HIV enzyme reverse transcriptase. Compared to the NRTI family of drugs, the diverse chemical class of non-nucleoside reverse transcriptase inhibitors (NNRTIs) has special anti-HIV activity with high specificity and low toxicity. However, current clinical usage of NRTI and NNRTI drugs has limited therapeutic value due to their adverse drug reactions and the emergence of multidrug-resistant (MDR) strains. To overcome drug resistance and efficacy issues, combination therapy is widely prescribed for HIV patients. Combination antiretroviral therapy (cART) includes more than one antiretroviral agent targeting two or more enzymes in the life cycle of the virus. Medicinal chemistry researchers apply different optimization strategies including structure- and fragment-based drug design, prodrug approach, scaffold hopping, molecular/fragment hybridization, bioisosterism, high-throughput screening, covalent-binding, targeting highly hydrophobic channel, targeting dual site, and multi-target-directed ligand to identify and develop novel NNRTIs with high antiviral activity against wild-type (WT) and mutant strains. The formulation experts design various delivery systems with single or combination therapies and long-acting regimens of NNRTIs to improve pharmacokinetic profiles and provide sustained therapeutic effects.

Abstract
Progressive structural brain changes are well documented in schizophrenia and have been linked to both illness progression and the extent of antipsychotic treatment exposure. Literature reporting longitudinal changes in brain structure in individuals with schizophrenia is selectively reviewed to assess the roles of illness, antipsychotic treatment, adherence and other factors in the genesis of these changes. This narrative review considers literature investigating longitudinal changes in brain structure in individuals with schizophrenia. The review focusses on structural changes in the cortex, basal ganglia and white matter. It also examines effects of medication non-adherence and relapse on the clinical course of the illness and on structural brain changes. Studies investigating structural magnetic resonance imaging changes in patients treated with long-acting injectable antipsychotics are reviewed. Temporal changes in brain structure in schizophrenia can be divided into those that are associated with antipsychotic treatment and those that are not. Changes associated with treatment include increases in basal ganglia and white matter volumes. Relapse episodes may be a critical factor in illness progression and brain volume reductions. Medication adherence may be an important factor that could explain the findings that brain volume reductions are associated with poor treatment response, higher intensity of antipsychotic treatment exposure and more time spent in relapse. Improved adherence via long-acting injectable antipsychotics and adherence focussed psychosocial interventions could maximize protective effects of antipsychotics against illness progression.

Abstract
AIM The purpose of this project is to assess the time-to-therapy discontinuation and hospital readmission rate among patients newly diagnosed with schizophrenia who are prescribed long-acting injectable versus oral dopamine receptor blocking agents. METHODS A retrospective review of medical records was performed for adult patients admitted to an 80-bed inpatient behavioural health facility with a new diagnosis of schizophrenia. The primary outcome studied was time to therapy discontinuation within 1 year of discharge, while secondary outcomes assessed were time-to-therapy discontinuation within 90 days and readmission rate at 30-days, 6 months, and 1 year. Multivariate Cox proportional hazard and linear regression modelling were used for statistical analysis. RESULTS A total of 425 patients were included in the analysis, with 66.4% (n = 282) discharged on oral and 33.6% (n = 143) on long-acting injectable dopamine receptor blocking agents. At 1 year post-discharge, the rates of discontinuation were 49.7% for those prescribed long-acting injectable and 55.7% for those prescribed oral formulations (adjusted hazard ratio = 0.54, p = .012). There was no statistically significant difference in readmission rate between the patients prescribed long-acting injectable and oral dopamine receptor blocking agents at any timepoint tested. CONCLUSIONS The use of long-acting injectable dopamine receptor blocking agents was associated with longer time-to-discontinuation compared to oral agents when prescribed to patients newly diagnosed with schizophrenia in the inpatient setting. However, this was not associated with significant reductions in rehospitalization, calling into question the clinical impact. Future studies will seek to confirm these findings using a prospective study design.

Abstract
BACKGROUND Paliperidone palmitate 6-month (PP6M) demonstrated noninferiority to paliperidone palmitate 3-month in preventing relapse in patients with schizophrenia in a phase 3 double-blind (DB) study (NCT03345342). Here, we report long-term efficacy and safety results from a 2-year single-arm, open-label extension (OLE; NCT04072575) of this DB study. METHODS Participants who completed the DB study without relapse were enrolled and followed-up every 3 months up to 2 years. Participants received 4 PP6M gluteal injections (700/1000 mg eq.) at baseline, 6-month, 12-month, and 18-month visits. Efficacy endpoints included assessment of relapse, Positive and Negative Syndrome Scale total score, Personal and Social Performance score, and Clinical Global Impression-Severity scale change from baseline. Safety was assessed by treatment-emergent adverse events (TEAEs), physical examinations, and laboratory tests. RESULTS Of 178 participants enrolled, 154 (86.5%) completed the OLE (mean age: 40.4 years, men: 70.8%; mean duration of PP6M exposure during OLE: 682.1 days). Overall, 7/178 (3.9%) participants relapsed between 20 and 703 days after enrolment. Mean (SD) changes from baseline to endpoint were as follows: Positive and Negative Syndrome Scale total score, 0.7 (8.22); Clinical Global Impression-Severity, 0.0 (0.51); and Personal and Social Performance Scale, 0.5 (7.47). Overall, 111/178 participants (62.4%) reported ≥1 TEAE; most common (>5%) TEAEs were headache (13.5%) and increased blood prolactin/hyperprolactinemia (18.0%); 8/178 (4.5%) participants experienced serious TEAEs, and 6/178 (3.4%) participants withdrew due to TEAEs. No deaths were reported. CONCLUSIONS The relapse rate observed with PP6M during the 2-year OLE was low (3.9%). Clinical and functional improvements demonstrated in the DB study were maintained during OLE, and no new safety concerns were identified. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT04072575; EudraCT number: 2018-004532-30.

Abstract
Administration of tuberculosis preventive therapy (TPT) to individuals with latent tuberculosis infection is an important facet of global tuberculosis control. The use of long-acting injectable (LAI) drug formulations may simplify and shorten regimens for this indication. Rifapentine and rifabutin have antituberculosis activity and physiochemical properties suitable for LAI formulation, but there are limited data available for determining the target exposure profiles required for efficacy in TPT regimens. The objective of this study was to determine exposure-activity profiles of rifapentine and rifabutin to inform development of LAI formulations for TPT. We used a validated paucibacillary mouse model of TPT in combination with dynamic oral dosing of both drugs to simulate and understand exposure-activity relationships to inform posology for future LAI formulations. This work identified several LAI-like exposure profiles of rifapentine and rifabutin that, if achieved by LAI formulations, could be efficacious as TPT regimens and thus can serve as experimentally determined targets for novel LAI formulations of these drugs. We present novel methodology to understand the exposure-response relationship and inform the value proposition for investment in development of LAI formulations that have utility beyond latent tuberculosis infection.

Abstract
Introduction Poor adherence to antipsychotic medication is common in the treatment of schizophrenia and other psychotic disorders. Paliperidone palmitate 3-monthly (PP3M) is the first long-acting injectable (LAI) antipsychotic to allow for only four medication administrations per year, and although there is sufficient information available about the clinical effects, there is relatively limited insight into the subjective experience of people with lived experience. Methods This descriptive, cross-sectional survey explored patient's satisfaction and perspectives on the advantages and disadvantages of switching from monthly to 3-monthly paliperidone while also reporting on perceived levels of safety with regard to the reducing dose regimen during the Covid-19 pandemic. Information on discontinuation and hospitalisation rates at one year was also collected from the electronic records. Results Of the 46 patients included in the study, the vast majority reported feeling satisfied (89.2%) and safer (93.5%) after switching to the three-monthly formulation. Participants highlighted several advantages of changing to PP3M, most notably convenience (93.5%), improved quality of life (58.7%), decreased stigma (39.1%) and better adherence (28.3%). Furthermore, 93.5% of respondents experienced no disadvantages, while 6.5% described worsening side effects or symptoms. In fact, only one patient discontinued PP3M at one year with the overall number of hospitalisations also reducing in the same period compared to the year before switching. Discussion Our findings add to the small, but growing, body of evidence supporting patient satisfaction and acceptance with the use of PP3M and may reinforce the use of less frequent LAIs in clinical practice to enhance individual experience and treatment persistence and decrease levels of stigmatisation.

Abstract
Aripiprazole 2-month ready-to-use 960 mg (Ari 2MRTU 960) is a novel long-acting injectable (LAI) formulation of aripiprazole monohydrate for administration once every 2 months, developed for the treatment of schizophrenia or maintenance monotherapy treatment of bipolar I disorder in adults (indication will vary by country). Aripiprazole lauroxil 1064 mg (AL 1064) is an LAI formulation of aripiprazole lauroxil, an aripiprazole prodrug, for administration once every 2 months, indicated for the treatment of schizophrenia in adults. This analysis provides an indirect comparison of aripiprazole plasma concentrations following multiple doses of either formulation. Clinical trial data were used to determine average steady-state aripiprazole plasma concentration (Cavg,ss), maximum aripiprazole plasma concentration (Cmax), and other pharmacokinetic parameters of either formulation following four administrations (96 patients received Ari 2MRTU 960; 28 patients received AL 1064). All pharmacokinetic parameters were considered in the context of a minimum aripiprazole therapeutic concentration (Cmin) of ≥95 ng/mL. An exposure-response analysis using data from two Phase III trials of aripiprazole once-monthly (an aripiprazole monohydrate LAI, administered monthly), showed that patients with a Cmin ≥95 ng/mL are 4.41 times less likely to relapse than patients with a Cmin <95 ng/mL. A similar analysis has not been performed for AL 1064. However, consensus guidelines for therapeutic drug monitoring recommend a range of 100-350 ng/mL for aripiprazole. Following four administrations, mean (standard deviation [SD]) Cavg,ss over the 2-month dosing interval was 263 (133) ng/mL for Ari 2MRTU 960 and 140.7 (57.3) ng/mL for AL 1064. Mean (SD) Cmax during the fourth dosing interval was 342 (157) ng/mL for Ari 2MRTU 960 and 188.8 (79.8) ng/mL for AL 1064. This indirect comparison showed that, following four administrations, Ari 2MRTU 960 and AL 1064 delivered mean aripiprazole plasma concentrations that remained above the minimum therapeutic concentration of aripiprazole over the 2-month dosing interval.

Abstract
Introduction Long-acting injectable (LAI) antipsychotics are a promising solution to combating issues related to nonadherence to oral antipsychotics. Oral overlap is utilized when an LAI is initiated to achieve therapeutic concentrations. The place in therapy in which additional overlap is warranted is often mistaken, and providers may prescribe additional overlap based on the presentation of the patient or misunderstanding of appropriate overlap. Methods This retrospective chart review assesses patients who were initiated on an LAI while admitted to the acute inpatient psychiatric unit from January 1, 2016, to December 31, 2019. The primary outcome assesses the appropriateness of oral overlap with LAIs. Secondary outcomes include adherence to oral overlap, discontinuation of an LAI within 4 months, and reason for discontinuation of LAI. Results A total of 62 patients were included: 40 (65%) had appropriate overlap, and 22 (35%) had inappropriate overlap. The most common LAI was paliperidone (n = 50, 81%). Patients were adherent to oral overlap in 67% (n = 6) of the appropriate overlap group and 85% (n = 17) of the inappropriate overlap group. Discontinuation of an LAI in 4 months occurred in 62.5% (n = 25) of the appropriate group and 40.9% (n = 9) of the inappropriate group. There were no significant differences in secondary outcomes when comparing adherence to oral overlap (p = .26), discontinuation of LAI within 4 months (p = .62), and reason for discontinuation (p = .69). Discussion This study identified that a majority of patients had appropriate prescribing of oral antipsychotic overlap.

Abstract
INTRODUCTION Long-acting injectable (LAI) formulations of second-generation antipsychotics (SGA) are a mainstay in the treatment of schizophrenia-spectrum patients, and their use improves adherence and reduces relapse risk. Personalizing LAI-based therapy involves tailoring the transition from oral to LAIs based on individual and drug-related pharmacokinetic peculiarities. AREAS COVERED We discuss pharmacokinetic considerations as a cornerstone of a smooth transition from oral to LAI SGAs based on works identified using an updated search in PubMed and Embase in February 2023. Establishing the extent of antipsychotic exposure during oral SGA-treatment from the patient's SGA levels is often a more appropriate orientation method to choose the equivalent LAI dose than population-based data. Oral dose adjustment during LAI transition can also be guided by checking SGA levels before the LAI injection. EXPERT OPINION LAI SGAs may dominate the maintenance treatment of schizophrenia-spectrum disorders with increased use for other severe mental illnesses such as bipolar disorder. Spurring this trend is the development of newer formulations with longer injection intervals and increased administration ease, but transitioning from oral SGA remains a challenge. By understanding the pharmacokinetics of LAI formulations and measuring SGA levels during oral therapy, one can personalize/optimize the switch from oral SGAs to LAI counterparts.

Abstract
Administration of tuberculosis preventive therapy (TPT) to individuals with latent tuberculosis infection is an important facet of global tuberculosis control. The use of long-acting injectable (LAI) drug formulations may simplify and shorten regimens for this indication. Rifapentine and rifabutin have anti-tuberculosis activity and physiochemical properties suitable for LAI formulation, but there are limited data available for determining the target exposure profiles required for efficacy in TPT regimens. The objective of this study was to determine exposure-activity profiles of rifapentine and rifabutin to inform development of LAI formulations for TPT. We utilized a validated paucibacillary mouse model of TPT in combination with dynamic oral dosing of both drugs to simulate and understand exposure-activity relationships to inform posology for future LAI formulations. This work identified several LAI-like exposure profiles of rifapentine and rifabutin that, if achieved by LAI formulations, could be efficacious as TPT regimens and thus can serve as experimentally-determined targets for novel LAI formulations of these drugs. We present novel methodology to understand the exposure-response relationship and inform the value proposition for investment in development of LAI formulations that has utility beyond latent tuberculosis infection.

Abstract
OBJECTIVE Review the pharmacology, pharmacokinetics, efficacy, safety, and role of long-acting injectable cabotegravir (CAB-LA) in HIV preexposure prophylaxis (PrEP). DATA SOURCES A literature search was performed using PubMed and Google Scholar (2012 to April 2022) with the search terms cabotegravir, preexposure prophylaxis, and PrEP. Other resources included abstracts presented at recent conferences, the manufacturer's Web site, prescribing information, and review articles. STUDY SELECTION AND DATA EXTRACTION All English-language articles of studies assessing the efficacy and safety of CAB-LA for PrEP were included. DATA SYNTHESIS CAB-LA is the first long-acting injectable therapy approved for HIV-1 PrEP in both men and women. It is a suspension given intramuscularly every other month. CAB-LA has been shown to be more effective than daily oral tenofovir disoproxil fumarate/emtricitabine (TDF/FTC) in preventing HIV-1 infection among high-risk individuals. Two phase 3 trials were stopped early on the basis of superior efficacy of CAB-LA. The most common adverse effects were injection site reactions (ISRs), although they tended to decrease over time, and few participants in clinical trials discontinued use due to ISRs. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE CAB-LA may be particularly useful for individuals with known adherence problems to oral therapy, those with renal impairment, and those with decreased bone mineral density. However, CAB-LA is more expensive than generic TDF/FTC and may be associated with weight gain. CONCLUSIONS CAB-LA is the first long-acting injectable agent for HIV PrEP. It is more effective than oral TDF/FTC, is well-tolerated aside from ISRs, and has few clinically significant drug-drug interactions.

Abstract
In this study, we present an innovative and facile in situ approach for extemporaneous preparation of sterile microparticles. An amazingly simple approach, in situ technology circumvents the stability, and scale up challenges as well as sterilization issues associated with long-acting particulate systems. Monophasic preconcentrates of donepezil base (DPZ), a model drug with a biodegradable polymer poly (DL-lactide-co-glycolide) (PLGA), with stabilizer were prepared by simple solution and sterilized by filtration (0.22 micron). The sterile preconcentrates when added to aqueous dextrose solution (total volume < 3 mL) generated ready-to-inject DPZ PLGA microparticles (DPZ-PLGA-MP) with high reproducibility, entrapment efficiency (> 80%), and size ~ 80 micron. DPZ micro suspension (DPZ-MS) with high precipitation efficiency (> 90%) and size ~ 80 micron was obtained in a similar manner omitting PLGA. XRD and DSC study confirmed decreased crystallinity in the presence of PLGA. No interaction between PLGA and DPZ was evident in the FTIR study. The microparticulate dispersions exhibited good in vitro injectability when tested using the texture analyzer (force < 5 N). When evaluated using the dialysis bag method (Himedia 12-14 kDa molecular weight cutoff), both microparticulate formulations exhibited controlled release up to 1 week in vitro. Further, low burst release of ~ 10% at the end of 6 h in the ex vivo chicken muscle study proposes great promise. Our data propose the facile extemporaneous generation of microparticles as a practical and promising approach for development of long-acting injectables. This facile approach could serve as platform technology for other drug candidates.

Abstract
Introduction Long-acting injectable antipsychotics (LAIs) have proven to be effective in the maintenance treatment of patients suffering from schizophrenia, and their safety and tolerability profiles represent a key factor in their long-term use and choice in clinical practice. Paliperidone palmitate (PP) is the only second-generation LAI (SGA-LAI), available in both one- (PP1M) and 3-month (PP3M) formulations. However, real-world prospective studies on PP1M and PP3M are still few and mostly conducted on small samples. In this context, we aimed to better define the safety and tolerability profile of PP using real world pharmacovigilance data. Methods We retrospectively analyzed the publicly available data regarding Individual Case Safety Reports (ICSRs), presenting PP1M and/or PP3M as suspected drugs, reported on EUDRAVigilance between 2011 and June 30th, 2022. ICSRs relative to at least one SGA-LAI other than PP, reported between 2003 and June 30th, 2022, were also examined as reference group. Data were evaluated with a descriptive analysis, and then, as disproportionality measures, crude reporting odds ratio (ROR) and 95% confidence interval (CI) were calculated. Results A total of 8,152 ICSRs met the inclusion criteria, of those 77.7% (n = 6,332) presented as suspected drug PP1M, 21.2% (n = 1,731) PP3M, while 89 cases indicated both PP1M and PP3M. Significantly higher probabilities of reporting in PP-related reports were observed for the primary Standardized MedDRA Queries "Sexual Dysfunctions" (ROR = 1.45; 95% CI 1.23-1.70), "Haemodynamic oedema, effusions and fluid overload" (ROR = 1.42; 1.18-1.70), as well as "Fertility disorders" (ROR = 2.69; 1.51-4.80). Discussion Our analysis indicates that the tolerability and safety profiles of PP are in line with what is known for the other SGA-LAIs. However, differences regarding endocrine system ADRs have been noticed. The results presented in this work do not discourage the prescription of SGA-LAI formulations but aim to enhance their safety.

Abstract
Purpose The aim of this study was to assess the efficacy and safety of paliperidone palmitate (PP) treatment compared with risperidone long-acting injectable (LAI) treatments for patients with schizophrenia. Patients and Methods Data mining was conducted in April 2022 across PubMed, Web of Science, Embase, the Cochrane Library, ClinicalTrials.gov, and PsycINFO. All published randomized controlled trials (RCTs) that assessed the effect of PP treatment for patients with schizophrenia when compared with the risperidone-LAIAs group were included. Relevant data were extracted and synthesized narratively. Results were expressed as standardized mean differences (SMDs) or risk ratios (RRs), with 95% confidence intervals (CIs). Results Four RCTs with 2451 patients met all the inclusion and exclusion criteria. Efficacy analyses showed no significant statistical differences in Positive and Negative Syndrome Scale (PANSS) total score changes at the endpoint (SMD = 0.10, P = 0.19), or in response rates (RR = 0.93; P = 0.40). Regarding the safety outcomes, PP treatment showed significantly increased risks of discontinuation rates for any reason (35.7% vs 30.4%; RR = 1.19; 95% CI, 1.03 to 1.39; P = 0.02) and nonsignificantly increased risks of total treatment emergent adverse events (TEAEs) (66.6% vs.64.8%; RR = 1.01; 95% CI, 0.94 to 1.09; P = 0.78) compared with the risperidone-LAIAs-treated group. Furthermore, PP may significantly increase total discontinuation rates compared with risperidone-LAIAs. Conclusion Our meta-analysis did not find a more beneficial effect of PP compared to risperidone-LAIAs treatments for schizophrenia. Clinicians should interpret and translate our data with caution, as the meta-analysis was based on a limited number of randomized controlled trials and patients.

Abstract
Purpose To examine efficacy and safety of paliperidone palmitate (PP) 6-month (PP6M) vs PP3-month (PP3M) long acting injectable (LAI) in patients with schizophrenia from European sites previously stabilized on PP3M or PP1-month (PP1M). Methods This post-hoc subgroup analysis used data from a global phase-3 double-blind (DB) randomized non-inferiority study (NCT03345342). Patients were randomized (2:1, respectively) to receive dorsogluteal injections of PP6M (700 mg eq. or 1000 mg eq.) or PP3M (350 mg eq. or 525 mg eq.) in the 12-month DB phase. Primary endpoint was time-to-relapse during the DB phase, using a Kaplan-Meier cumulative survival estimate (non-inferiority margin 95% CI lower bound larger than prespecified as -10%). Treatment emergent adverse events (TEAEs), physical examinations, and laboratory tests were also evaluated. Results A total of 384 patients who entered the DB phase were included in European sites (PP6M, n = 260; PP3M, n = 124) with a mean age similar in both groups (mean age [SD] years: PP6M, 40.0 [11.39]; PP3M, 38.8 [10.41]). Baseline characteristics were similar across both groups. The number of patients who experienced a relapse during DB phase were PP6M: 18 (6.9%) vs PP3M: 3 (2.4%) with percentage relapse-free difference of -4.9% (95% CI: -9.2%, -0.5%), thus achieving non-inferiority criteria. Secondary efficacy endpoints indicated comparable improvements. Incidence of TEAEs was similar between PP6M (58.8%) and PP3M (54.8%) groups. Nasopharyngitis, headache, increased weight, and injection-site pain were the most common TEAEs. Conclusion The efficacy of PP6M was non-inferior to that of PP3M in preventing relapse in the European subgroup previously treated with PP1M or PP3M, which was consistent with the global study. No new safety signals were identified.

Abstract
OBJECTIVE To analyze the effect of Risperidone ISM on social functioning and health-related quality of life (HR-QoL) in both short- and long-term treatment of patients with schizophrenia. PATIENTS AND METHODS This analysis was based on data from both phases of the PRISMA-3 study, including 433 relapsed patients from the double-blind (DB) phase of the PRISMA-3 trial who were treated for 12-weeks with once-monthly (every 28 days) intramuscular Risperidone ISM 75 mg or 100 mg (n = 288), or placebo (n = 145), as well as 174 patients transitioning from the DB to an open-label 52-week extension (OLE) phase, plus 41 de novo patients treated on a stable maintenance dose of oral risperidone. The clinician-administered Personal and Social Performance (PSP) scale and the patient-reported 20-item Subjective Well-being under Neuroleptics scale (SWN-20) were used to measure social functioning and HR-QoL outcomes, respectively. RESULTS Risperidone ISM significantly improved PSP total score from baseline to endpoint (Day 85) versus placebo in the DB phase with mean change total score (95% CI) of 10.7 (9; 12) compared to 4.8 (3; 7) for placebo (p < 0.0001). The statistically significant improvement was present from the first measurement time point (Day 29). SWN-20-measured HR-QoL increased on average in patients treated with Risperidone ISM in the DB phase. A significant improvement was also observed for PSP and SWN-20 scores from the OLE baseline to week 52 for patients transitioning from the DB phase. Stable de novo patients maintained similar PSP and SWN-20 scores during the whole OLE phase. CONCLUSION Risperidone ISM provided a rapid and sustained improvement in personal and social functioning, and HR-QOL without need of oral risperidone supplementation or loading doses. These findings, along with a fast onset of efficacy, could contribute to reinforcing the therapeutic alliance and possibly an earlier discharge. Moreover, patient functioning continued improving or was maintained with long-term treatment.

Abstract
AIM To evaluate the impact of timing of aripiprazole once-monthly (AOM) initiation on healthcare resource utilization (HCRU), risk of hospitalization, and healthcare costs in patients with schizophrenia. METHODS A retrospective cohort study was conducted using data from the Merative MarketScan database (01/01/2013-12/31/2019). Adults aged ≥18 years with a new episode of care for schizophrenia and an AOM claim were included. Patients were classified into two cohorts based on the time between the first schizophrenia diagnosis and the first AOM claim (early cohort: ≤1 year; late cohort: >1 year). All-cause and psychiatric-specific HCRU, risk of hospitalization, and healthcare costs were evaluated over 1-year post-AOM initiation. The relationship between the timing of AOM initiation and HCRU was evaluated using negative binomial regression, and healthcare costs using generalized linear models (log-link with gamma distribution). Logistic regression was used to estimate the likelihood of hospitalization during the follow up period for both all-cause and psychiatric-specific hospitalization. RESULTS A total of 945 patients were included (early cohort: n = 525; late cohort: n = 420). At baseline, the early cohort had lower mean age, a greater proportion of males, and a lower mean Charlson Comorbidity Index score than the late cohort (all p < .05). After adjusting for baseline demographic and clinical characteristics, all-cause and psychiatric-specific hospitalization during the 1-year follow-up period were statistically significantly higher for the late cohort versus the early cohort (all-cause: incident rate ratio [IRR] = 1.63, 95% confidence interval [CI]: 1.28-2.07, p < .01; psychiatric-specific: IRR = 1.93, 95% CI: 1.46-2.55, p < .01). The early cohort had statistically significantly lower adjusted all-cause ($21,686 versus $29,033; p = .0002) and psychiatric-specific ($24,414 versus $32,461; p = .0002) healthcare costs versus the late cohort. LIMITATIONS This study utilized claims data, which are intended for administrative purposes rather than for research. CONCLUSIONS This analysis extends previous evidence for the benefits of AOM in patients with new episodes of schizophrenia, by demonstrating lower HCRU, risk of hospitalization, and healthcare costs with early AOM initiation compared with later initiation.

Abstract
Medication nonadherence in schizophrenia can have serious implications including relapses and hospitalization. Long-acting injectable (LAI) antipsychotics require fewer administrations, while ensuring sustained medication coverage. In this review, we summarize the expected real-world benefits of longer dosing intervals in the management of schizophrenia. LAIs are associated with improved clinical outcomes of less frequent relapses and reduced functional impairment, encouraging patients to regain control of their lives. Aripiprazole lauroxil and paliperidone palmitate three-monthly (PP3M) LAIs have longer dosing intervals of 2-3 months and provide improved outcomes in patients with schizophrenia. Paliperidone palmitate six-monthly (PP6M) LAI provides the longest dosing interval, twice-yearly dosing, among existing LAIs. Decreasing the frequency of LAI administrations has the potential to reduce occurrence of serious outcomes associated with poor medication adherence. By eliminating the need for daily oral antipsychotic dosing, LAIs could increase the likelihood of patient acceptance, decrease stigma, and promote self-esteem. Longer intervals of medication coverage may be desirable for patients with higher risk of relapse including adults with recent-onset schizophrenia, those living in circumstances that may deprive them of regular access (eg, homeless), those that are in transitions between care settings or to reduce interpersonal contact during public health emergencies (eg, COVID-19 pandemic).

Abstract
To assess the impact of the route of administration and doses of second-generation antipsychotics (SGAs) on treatment adherence, hospital admissions, and suicidal behaviour in patients with severe schizophrenia (Clinical Global Impression−Severity−CGI-S ≥ 5), we implemented an observational 5-year follow-up study. A total of 37.5% of the patients on oral antipsychotics (Aps) and 11.5% of those on long-acting injectables (LAIs) abandoned the treatment (p < 0.001). There were no differences in treatment discontinuation between the LAI-AP standard and high-dose groups. A total of 28.1% of the patients on oral Aps had at least one hospitalisation, as well as 13.1% of patients on LAIs (p < 0.001). There were fewer hospitalisations of patients on LAIs in the high-dose group (p < 0.05). Suicide attempts were recorded for 18% of patients on oral Aps but only for 4.6% of patients on LAIs (p < 0.001). No differences were found between the dosage groups on LAIs. Tolerability was good for all Aps and somewhat better for LAIs than oral Aps in terms of side effects (p < 0.05). There were no differences between the standard and high-dose groups. More patients discontinued treatment due to side effects in the oral AP group (p < 0.01). LAI SGA treatment was more effective than oral AP in terms of adherence and treatment outcomes for managing people with severe schizophrenia. Moreover, significant improvements were found that favour high-dose LAI SGA treatment for some of these patients. This study highlights the need to consider LAI antipsychotics and high-dose strategies for patients with severe schizophrenia.

Abstract
OBJECTIVE Long-acting injectable buprenorphine (LAI-BPN) was introduced in recent years as a novel treatment for opioid use disorder. Despite growing evidence-base of its effectiveness, there is limited research on the relationship between this treatment and patient characteristics. METHODS This descriptive, retrospective cohort study compared sociodemographic and clinical variables between patients treated with SL-BPN and those treated with LAI-BPN at a large metropolitan health service in Queensland, Australia. RESULTS Patients that transitioned to LAI-BPN were more likely to be single, have a comorbid mental illness, untreated hepatitis C infection and longer duration of unsanctioned opioid use. Patients continuing treatment with SL-BPN were more likely to fail to attend appointments and have urine drug screen results positive for gabapentinoids. CONCLUSIONS The results of this study contribute to currently limited literature on this novel treatment option in an Australian context, highlighting factors which may influence patient and prescriber treatment choices. Clinicians may be more inclined to prescribe LAI-BPN to patients with higher psychosocial comorbidity to facilitate engagement in treatment.

Abstract
Long-acting injectable pre-exposure prophylaxis (LAI-PrEP) was recently approved for HIV prevention as an alternative to daily oral PrEP. We explored preferences and attitudes toward LAI-PrEP among Black, Hispanic/Latino, and White gay, bisexual, and other men who have sex with men (GBM) using focus groups (n = 13) and in-depth interviews (n = 17). Participants expressed differing levels of interest in LAI-PrEP. While important benefits of LAI-PrEP included convenience, provider-facilitated PrEP discussion, and expansion of PrEP options, participants raised concerns about treatment efficacy and side effects, discomfort with needles/injections, cost, and frequency of clinic visits. Our findings highlight ongoing challenges with accessing HIV-prevention tools and provide guidance for developing strategies to enhance LAI-PrEP uptake among GBM.

Abstract
In the present work, Risperidone microparticles from poly(lactic acid)/poly(hexylene succinate) (PLA-b-PHSu) block copolymers in different ratios, 95/05, 90/10 and 80/20 w/w, were examined as long-acting injectable formulations. Nuclear magnetic resonance (NMR) was used to verify the successful synthesis of copolymers. Enzymatic hydrolysis showed an increase in weight loss as the content of PHSu increased, while the cytotoxicity studies confirmed the biocompatibility of the copolymers. The polyesters were further used to encapsulate Risperidone by spray drying. The drug-loaded microparticles were studied by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and X-ray diffraction (XRD). SEM microphotographs confirmed that spherically shaped microparticles were prepared with sizes about 5-12 μm, while XRD and differential scanning calorimetry (DSC) studies evidenced that Risperidone was encapsulated in amorphous form. The drug loading and the entrapment efficiency of Risperidone were studied as well as the in vitro release from the prepared microparticles. As the content of PHSu increased, a higher release of Risperidone was observed, with PLA-b-PHSu 80/20 w/w succeeding to release 100% of RIS within 12 days. According to theoretical modeling, the kinetics of RIS release from PLA-b-PHSu microparticles is complex, governed by both diffusion and polymer erosion.

Abstract
Objectives: While long-lasting antipsychotics (LLA) were specifically developed to address the problem of adherence in patients with chronic psychiatric disorders, their role in pediatric populations is not clear. Methods: To document the efficacy, tolerance, and acceptance of LLAs in children and adolescents, a literature search was conducted using several databases for published studies (PubMed, PsycINFO) from January 1965 to December 2020. Twenty-two studies were identified (16 case reports/series, 3 open label studies, 2 controlled studies, and 1 retrospective analysis of national database). Results: Demographic features were widely heterogeneous across studies (total N = 480, 58% male, mean age = 15.0 ± 1.8). Case reports/series presented positive therapeutic outcomes in noncompliant youths with severe mental illness. Three open-label one-arm studies supported the clinical efficacy of risperidone long-acting injection in patients previously stabilized with oral risperidone. One study showed lower clinical symptoms and higher functioning at 12 months in youths treated for an acute psychotic episode with paliperidone palmitate compared to oral risperidone. The types and rates of side effects of LLA were comparable to those observed for oral antipsychotics. Two studies suggested better metabolic and neurological tolerance of LLA compared to an oral form. Preliminary evidence supported a satisfactory level of treatment satisfaction in patients treated with LLA and their families, while concerns were raised regarding practical administration in outpatient services. However, the average quality of the evidence based on the RoB2 tool was low. Conclusions: The level of evidence was low for the efficacy of LLA in pediatric populations and very low for the tolerance and acceptance. It concerned mostly the effect of risperidone long-acting injection in adolescents with psychotic disorders. Randomized maintenance clinical trials using noninferiority analysis would be more appropriate for further research.

Abstract
Background Noninterventional naturalistic studies are an important complement to randomized controlled trials. Aripiprazole once-monthly (AOM) is an atypical antipsychotic in a long-acting injectable formulation. Methods A pooled analysis of two noninterventional studies was undertaken to validate previous results on AOM effectiveness and safety in a larger population and improve statistical power for preplanned subgroup analyses. We analyzed data from 409 patients with schizophrenia who were treated with AOM and were enrolled in noninterventional studies in Germany (via noninterventional studies registry 15,960 N) and Canada (NCT02131415). Data collected at baseline, 3 and 6 months were analyzed. Among the endpoints were psychopathology (brief psychiatric rating scale [BPRS]) and disease severity (clinical global impression [CGI]). Results Mean patient age was 38.9 (SD 14.8) years, and 59.9% were male. BPRS decreased from 48.1 (SD 15.6) at baseline to 36.5 (SD 13.7) at month 6 (p < 0.001). CGI decreased from 4.47 (SD 0.90) at baseline to 3.64 (SD 1.16) at month 6 (p < 0.001). A total of 54.4% were responders (at least 20% reduction) on the BPRS, and 56.5% had a CGI-S-score that was at least 1 level better than baseline. A total of 43.4% were considered responders on both the BPRS and CGI scales. A total of 45.2% were considered in remission. Adverse events were rare and corresponded to the previously known safety profile of AOM. Conclusions Treatment with AOM for patients with schizophrenia appeared effective and safe under real-life conditions.

Abstract
OBJECTIVES Aripiprazole is an antipsychotic with a partial agonism of dopamine D2 and D3 receptors. This differential mechanism implies a rigorous appraisal of the appropriate therapeutic strategies in certain situations. To answer currently unsolved clinical questions about the use of oral and long-acting injectable (LAI) aripiprazole, we present here an expert consensus from 12 Spanish psychiatrists and a pharmacologist with extensive experience in the use of this antipsychotic. METHODS Through one face-to-face session and online collaboration, we reached consensus and established practical recommendations based on scientific evidence and clinical experience. We classified the available scientific literature according to SIGN system and attributed a level of evidence to each reviewed article. RESULTS The recommendations were divided according to (i) chronological dimension (based on previous treatments, including patients naïve or not to antipsychotic treatment and maintenance regimen), and (ii) dimension related to therapeutic options, comprising switches to aripiprazole and the most used combinations with this antipsychotic. CONCLUSIONS We recommend considering aripiprazole as first treatment option in the early stages of schizophrenia and in patients with affective symptoms and contemplating a switch to aripiprazole LAI in all candidate patients. Importantly, switches from other antipsychotics should consider previous antipsychotic history and exposure to aripiprazole. KEYPOINTSAripiprazole can be considered as first treatment option in early stages of schizophrenia and in patients with significant affective symptoms.Aripiprazole LAI shows better adherence than oral aripiprazole and could be considered in all candidate patients.Before switching to aripiprazole, detailed information about previous antipsychotic history should be gathered.Switch to aripiprazole should be managed differently for aripiprazole naïve and non-naïve patients.Rigorous and controlled studies on antipsychotics in real clinical practice should be carried out.

Abstract
AIM Long-acting injectable antipsychotic drugs (LAIs) are often used as an alternative to oral antipsychotics (OAPs) in individuals with psychosis who demonstrate poor medication adherence. Previous meta-analyses have found mixed results on the efficacy of LAIs, compared to OAPs, in patients with psychotic disorders. The objective of this meta-analysis was to compare the effectiveness of using LAIs versus OAPs in the early stages of psychosis. METHODS Major electronic databases were used to search for any studies examining the comparative effectiveness (i.e., relapse, adherence, hospitalization, and all-cause discontinuation) of any LAIs versus OAPs in early stages of psychosis. Studies published up to 6 June, 2019 were included and no language restriction was applied. Inclusion criteria were a diagnosis of schizophrenia or related disorder, where patients were in their first episode or had a duration of illness ≤5 years. Data were analysed using a random-effects model. RESULTS Fifteen studies (n = 10 584) were included, of which were 7 RCTs, 7 observational studies, and 1 post-hoc analysis. We found that LAIs provided advantages over OAPs in terms of relapse rates. No significant differences were found between LAI and OAP groups in terms of all-cause discontinuation, hospitalization, and adherence rates. However, considering only RCTs revealed advantages of LAIs over OAPs in terms of hospitalization rates. CONCLUSIONS LAIs may provide benefits over OAPs with respect to reducing relapse and hospitalization rates in early psychosis patients. There is a need for larger and better-designed studies comparing OAPs and LAIs specifically in early psychosis patients.

Abstract
In implementing the decisions in the landmark case Sell v. United States, jurisdictions have adopted mechanisms for the involuntary medication of defendants to restore competency to stand trial. These procedures attempt to balance the liberty and privacy rights of the accused against the government's responsibility to ensure timely prosecution and fair trial. The question of which medications are most appropriate for this goal, however, remains open. This article reviews the legal status of the administration of long-acting injectable (LAI) antipsychotics for sustained competency restoration. We explore case law and discuss the theoretical and empirical benefits and drawbacks to this practice, considering recent technological advancements in LAI development. Some courts have regarded LAI use pursuant to Sell as equivalent or superior to immediate-acting medications, whereas others have regarded LAIs as either more intrusive or medically riskier. We conclude that the use of LAIs may be carefully integrated into treatment plans to restore and maintain trial competency amid competing interests.

Abstract
TV‐46000 is a long‐acting subcutaneous antipsychotic that uses a novel copolymer drug delivery technology in combination with a well‐characterized molecule, risperidone, that is in clinical development as a treatment for schizophrenia. A population pharmacokinetic (PPK) modeling and simulation approach was implemented to identify TV‐46000 doses and dosing schedules for clinical development that would provide the best balance between clinical efficacy and safety. The PPK model was created by applying pharmacokinetic data from a phase 1 study of 97 patients with a diagnosis of schizophrenia or schizoaffective disorder who received either single or repeated doses of TV‐46000. The PPK model was used to characterize the complex release profile of the total active moiety (TAM; the sum of the risperidone and 9‐OH risperidone concentrations) concentration following subcutaneous injections of TV‐46000. The PK profile was best described by a double Weibull function of the in vivo release rate and by a 2‐compartment disposition and elimination model. Simulations were performed to determine TV‐46000 doses and dosing schedules that maintained a median profile of TAM concentrations similar to published TAM exposure following oral risperidone doses that have been correlated to a 40% to 80% dopamine‐D2 receptor occupancy therapeutic window. The simulations showed that therapeutic dose ranges for TV‐46000 are 50 to 125 mg for once‐monthly and 100 to 250 mg for the once every 2 months regimens. This PPK model provided a basis for prediction of patient‐specific exposure and dopamine‐D2 receptor occupancy estimates to support further clinical development and dose selection for the phase 3 studies.

Abstract
PURPOSE OF REVIEW This paper provides a critical review of recent therapeutic advances in long-acting (LA) modalities for human immunodeficiency virus (HIV) treatment and prevention. RECENT FINDINGS LA injectable antiretroviral therapy (ART) has been approved in the United States, Canada and Europe; the United States also has approved LA injectable preexposure prophylaxis (PrEP) and the World Health Organization has recommended the vaginal PrEP ring. Current LA PrEP modalities in clinical trials include injections, films, rings, and implants; LA ART modalities in trials include subcutaneous injections and long-term oral pills. Although LA modalities hold incredible promise, global availability is inhibited by long-standing multilevel perils including declining multilateral funding, patent protections and lack of political will. Once available, access and uptake are limited by factors such as insurance coverage, clinic access, labor markets, stigma, and structural racism and sexism. These must be addressed to facilitate equitable access for all. SUMMARY There have been tremendous recent advances in the efficacy of LA ART and PrEP modalities, providing renewed hope that 'ending the HIV epidemic' is within reach. However, pervasive socio-structural inequities limit the promise of LA modalities, highlighting the need for cautious optimism in light of the embedded inequities in the trajectory of research, development, and population-level implementation.

Abstract
BACKGROUND Non-adherence to antipsychotics in schizophrenia is associated with an increased risk of psychotic relapse and hospitalization, a risk that is reduced with the use of long-acting injectable (LAI) antipsychotics. Randomized clinical trials (RCTs) have demonstrated the efficacy of paliperidone palmitate 3-monthly (PP3M) for psychotic relapse prevention in schizophrenia, but it remains poorly documented among individuals treated in real-life settings who can benefit the most out of LAIs. OBJECTIVES The objective of this study was to evaluate the effectiveness of PP3M in relapse prevention among patients with schizophrenia. METHODS This is a multicentre retrospective study conducted in four outpatients' clinics across Canada. All consecutive patients with a main diagnosis of schizophrenia who initiated PP3M between June 2016 and March 2020 were included. The primary outcome was psychotic relapse, defined using broad and clinically relevant criteria. RESULTS Among 178 consecutive patients who were switched to PP3M, the 12-month relapse rate was 18.5% and the relapse-free survival probability was 0.788 (95% confidence interval [CI] = 0.725-0.856). Comorbid diagnoses of personality disorders and substance use disorders were associated with hazard rates (HRs) of 3.6 (95% CI = 1.8-7.3, p < 0.001) and 3.1 (95% CI = 1.6-6.2), respectively. Increased psychopathology severity was associated with an increased likelihood of relapse, while having a job or being in school was protective. CONCLUSION These findings reinforce the necessity of conducting research in patients with comorbid psychiatric disorders who are typically underrepresented in RCTs, yet overrepresented in real-life settings, in order to better inform and guide clinical practice.

Abstract
AIMS Provide the first national description across the US of variations in healthcare measures in 2018 among Medicaid beneficiaries with schizophrenia. MATERIALS AND METHODS Adult beneficiaries with ≥2 diagnoses for schizophrenia, and continuous enrollment with consistent geographical data in all of 2018 were identified from Transformed Medicaid Statistical Information System (T-MSIS) Analytic Files (TAF) data for 45 of 50 states. Antipsychotic (AP) utilization rates, including long-acting injectable APs (LAIs), quality metrics, and all-cause healthcare resource utilization and costs for claims submitted to Medicaid were reported nationally and by state. Pearson correlation evaluated associations between LAI utilization and total healthcare costs at state and county levels. RESULTS Across the US 688,437 patients with schizophrenia were identified. The AP utilization rate was 51% (state range: 24-77%), while the LAI utilization rate was 13% (range: 4-26%). The proportion of patients adherent to any AP was 56% (range: 19-73%). Within 30 days post-discharge from an inpatient admission, 22% (range: 8-58%) of patients had an outpatient visit, and 12% (range: 4-48%) had a readmission. The proportion of patients with ≥1 inpatient admission and ≥1 emergency room visit was 34% (range: 19-82%) and 45% (range: 20-70%). Per-patient-per-year total healthcare costs averaged $32,920 (range: $717-$93,972). At the county level, a weak negative correlation was observed between LAI utilization and total healthcare costs. LIMITATIONS This study included Medicaid beneficiaries enrolled with pharmacy and medical benefits, including beneficiaries dually eligible for Medicare; results cannot be generalized to the overall schizophrenia population or those with other payer coverage. CONCLUSIONS In 2018, half of beneficiaries with schizophrenia did not submit any claims for APs to Medicaid, nearly half had an emergency room visit, and one-third had an inpatient admission. Moreover, healthcare measures varied considerably across states. These findings may indicate unmet treatment needs for Medicaid beneficiaries with schizophrenia.

Abstract
Preventing the relapse of a psychotic episode is a challenge for the treatment of schizophrenia. Patients with schizophrenia suffer from a few to a dozen relapses in their lifetime. The use of long-acting injectable (LAI) antipsychotics in the treatment of schizophrenia is associated with less frequent recurrences of psychotic symptoms, better compliance, and better quality of life. The aim of the report is to present the findings of the successful management of treatment-resistant schizophrenia in a patient with persistent non-compliance using a combination of typical and atypical LAI antipsychotics. Since there was a history of non-adherence (irregular controls in outpatient clinics) by the patient, clozapine was not considered a therapeutic option. At the start of the treatment, olanzapine LAI was administered to the patient at a dosage of 300 mg fortnightly because of the good response and tolerance reported in the previous treatment. The treatment was continued for several weeks, and because of the persistence of constant delusions, labile affect, and aggressive behavioral tendencies, a second antipsychotic, zuclopenthyxole, was added, which was initially administered orally. After 4 weeks of combined treatment, the patient's mental state improved. There was no report of delusions, and his mood was much more stable. Zuclopenthyxole was switched to the LAI antipsychotic form due to the patient's history of persistent non-compliance, lack of insight into the disease, and the risk of aggressiveness toward others. Then, 200 mg of zuclopenthyxole decanoate was administered fortnightly. The patient was discharged from the hospital without any symptoms of delusions or hallucinations. The patient's clinical state presented negative symptoms, of which avolition and diminished social activity were dominant. The patient tolerated the treatment well, and sedation and extrapyramidal symptoms were not observed. The patient continued the injections alternately (one injection per week) to obtain regular visits to the outpatient clinic.

Abstract
OBJECTIVES Knowledge about the impact of body composition features on pharmacokinetics of newer long-acting injectable antipsychotics is limited. METHODS We analyzed steady-state plasma concentrations of paliperidone in different body mass index (BMI), age, sex, and smoking status patient subgroups treated with once-monthly paliperidone palmitate (PP1M). Paliperidone plasma concentrations and dose-adjusted-plasma concentrations (C/D) from a therapeutic drug monitoring (TDM) database of PP1M-treated patients were compared among normal BMI, overweight, and obese patients as well as between females vs. males, elderly vs. non-elderly, and smokers vs. non-smokers using non-parametric tests. RESULTS In a total of 183 PP1M-treated patients, we found highly variable paliperidone plasma concentrations between individuals but no significant effect of PP1M dose or dosing intervals (p> 0.05). C/D ratios were similar in 54 obese, 82 overweight, and 47 normal BMI patients (p> 0.05). Females had 13.7% higher C/D ratios compared to males, yet this difference was not significant (p> 0.05). No differences were found between elderly vs. non-elderly patients or for smokers vs. non-smokers (p> 0.05). CONCLUSION Our findings suggest that age, sex, smoking, or body weight may not substantially affect pharmacokinetic indices of PP1M. The high interindividual variation of plasma concentrations implies that TDM may be helpful to enhance PP1M efficacy and tolerability.

Abstract
Background: Long-acting injectable (LAI) antipsychotics are efficacious in managing psychotic symptoms in people affected by severe mental disorders, such as schizophrenia and bipolar disorder. The present study aimed to investigate whether attitude toward treatment and treatment adherence represent predictors of symptoms changes over time. Methods: The STAR Network "Depot Study" was a naturalistic, multicenter, observational, prospective study that enrolled people initiating a LAI without restrictions on diagnosis, clinical severity or setting. Participants from 32 Italian centers were assessed at three time points: baseline, 6-month, and 12-month follow-up. Psychopathological symptoms, attitude toward medication and treatment adherence were measured using the Brief Psychiatric Rating Scale (BPRS), the Drug Attitude Inventory (DAI-10) and the Kemp's 7-point scale, respectively. Linear mixed-effects models were used to evaluate whether attitude toward medication and treatment adherence independently predicted symptoms changes over time. Analyses were conducted on the overall sample and then stratified according to the baseline severity (BPRS < 41 or BPRS ≥ 41). Results: We included 461 participants of which 276 were males. The majority of participants had received a primary diagnosis of a schizophrenia spectrum disorder (71.80%) and initiated a treatment with a second-generation LAI (69.63%). BPRS, DAI-10, and Kemp's scale scores improved over time. Six linear regressions-conducted considering the outcome and predictors at baseline, 6-month, and 12-month follow-up independently-showed that both DAI-10 and Kemp's scale negatively associated with BPRS scores at the three considered time points. Linear mixed-effects models conducted on the overall sample did not show any significant association between attitude toward medication or treatment adherence and changes in psychiatric symptoms over time. However, after stratification according to baseline severity, we found that both DAI-10 and Kemp's scale negatively predicted changes in BPRS scores at 12-month follow-up regardless of baseline severity. The association at 6-month follow-up was confirmed only in the group with moderate or severe symptoms at baseline. Conclusion: Our findings corroborate the importance of improving the quality of relationship between clinicians and patients. Shared decision making and thorough discussions about benefits and side effects may improve the outcome in patients with severe mental disorders.

Abstract
We collected 216 responses from sexually active MSM, transgender women, and gender-nonconforming (GNC) people of color through a web-based survey to understand the facilitators and barriers to research participation in a hypothetical LAI PrEP trial. In adjusted models, these items were found to be significantly associated with research participation likelihood: ever participated in HIV research study; comfort with taking daily pill; comfort with providing urine sample; and concerns over potential side effects of shot. Asian participants were more concerned about others knowing they were being recruited than were Black and Latinx respondents F(2, 216) = 3.98; p < .05. Asian respondents were also less comfortable with being recruited at organizations serving communities of color than Black and Latinx respondents, F(2, 216) = 5.10; p < .05. Cisgender respondents were more comfortable with being recruited by a friend or colleague than were transgender/GNC respondents, F(1, 215) = 4.8; p < .05.
