Abstract
In a retrospective study conducted in three hospitals in Paris, generic antiretroviral accounted for 30.2% of all prescriptions. Tenofovir disoproxil/emtricitabine (TDF/FTC) was the most prescribed generic ART (82.3% of generic prescriptions). Generic ART (gART) was more likely to be prescribed to women, to patients less than 50 years, and with recent HIV diagnosis less than 3 years. Physicians prescribed more gART if they were men, older than 55 years or worked at a university teaching hospital.

Abstract
BACKGROUND In British Columbia, antiretrovirals (ARVs) for HIV treatment (HIV-Tx) and pre-exposure prophylaxis (PrEP) are free-of-charge through publicly-funded Drug Treatment Programs (DTPs). When available, less costly generics are substituted for brand-name ARVs. We describe the incidence and type of product substitution issue (PSI) adverse drug reactions (ADRs) attributed to generic ARVs. METHODS Cohorts included DTP clients ≥19 years who received generic ARVs for HIV-Tx (abacavir-lamivudine, emtricitabine-tenofovir DF, efavirenz-emtricitabine-tenofovir DF, atazanavir or darunavir between 01 Jun 2017 and 30 Jun 2022) or PrEP (emtricitabine-tenofovir DF, 01 Apr 2018 to 30 Jun 2022). Demographic, ARV and ADR data were extracted from DTP databases and summarized by descriptive statistics. PSI incidence was calculated for each product during the year following brand-to-generic and generic-to-generic transitions (first-year-post-rollout), and compared between generic versions using generalized estimating equations. For context, incidence of any ARV product-related ADR was calculated in the same 1-year periods. RESULTS During first-year-post-rollout periods, 5339 HIV-Tx (83% male, median age 52 years) and 8095 PrEP (99% male, median 33 years) clients received generic ARVs, and reported 78 and 23 generic PSIs, respectively. PSI incidence was <1% for most generic ARVs, with mild-moderate symptoms including gastrointestinal upset, headache, dizziness, fatigue/malaise and skin rash. In HIV-Tx clients, the efavirenz-containing product had higher PSI incidence than other ARVs (2.2%, p = .004), due to more neuropsychiatric adverse reactions. Any ADR incidence was stable across measurement periods, and generic PSIs represented less than one third of all product-related ADRs. CONCLUSIONS Generic substitution of antiretrovirals for HIV-Tx and PrEP was well tolerated, with ≤2% incidence of mild-moderate PSI ADRs.

Projected Benefits of Long-Acting Antiretroviral Therapy in Nonsuppressed People With Human Immunodeficiency Virus Experiencing Adherence Barriers. Open Forum Infect Dis 2023; 10:ofad390. [PMID: 37601728 PMCID: PMC10439527 DOI: 10.1093/ofid/ofad390] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Accepted: 07/19/2023] [Indexed: 08/22/2023] Open
Abstract
Background In a demonstration project, long-acting, injectable cabotegravir-rilpivirine (CAB-RPV) achieved viral suppression in a high proportion of people with HIV (PWH) who were virologically nonsuppressed with adherence barriers. We projected the long-term impact of CAB-RPV for nonsuppressed PWH experiencing adherence barriers. Methods Using the Cost-Effectiveness of Preventing AIDS Complications (CEPAC) model, we compared 3 strategies: (1) standard of care oral integrase inhibitor-based ART (INSTI); (2) INSTI-based ART with supportive social services ("wraparound services" [WS]) (INSTI/WS); and (3) CAB-RPV with WS (CAB-RPV/WS). Model outcomes included viral suppression (%) and engagement in care (%) at 3 years, and life expectancy (life-years [LYs]). Base case cohort characteristics included mean age of 47y (standard deviation [SD], 10y), 90% male at birth, and baseline mean CD4 count 150/µL (SD, 75/µL). Viral suppression at 3 months was 13% (INSTI), 28% (INSTI/WS), and 60% (CAB-RPV/WS). Mean loss to follow-up was 28/100 person-years (PY) (SD, 2/100 PY) without WS and 16/100 PY (SD, 1/100 PY) with WS. Results Projected viral suppression at 3 years would vary widely: 16% (INSTI), 38% (INSTI/WS), and 44% (CAB-RPV/WS). Life expectancy would be 7.4 LY (INSTI), 9.0 LY (INSTI/WS), and 9.4 LY (CAB-RPV/WS). Projected benefits over oral ART would be greater for PWH initiating CAB-RPV/WS at lower CD4 counts. Across plausible key parameter ranges, CAB-RPV/WS would improve viral suppression and life expectancy compared with oral INSTI strategies. Conclusions These model-based results support that long-acting injectable CAB-RPV with extensive support services for nonsuppressed PWH experiencing adherence barriers is likely to increase viral suppression and improve survival. A prospective study to provide further evidence is needed.

Clin Infect Dis 2023; 76:1793-1801. [PMID: 36594172 PMCID: PMC10209438 DOI: 10.1093/cid/ciac981] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Revised: 10/21/2022] [Accepted: 12/29/2022] [Indexed: 01/04/2023] Open
Abstract
BACKGROUND Limited information exists about testing for human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) among Medicaid enrollees after starting medication for opioid use disorder (MOUD), despite guidelines recommending such testing. Our objectives were to estimate testing prevalence and trends for HIV, HBV, and HCV among Medicaid enrollees initiating MOUD and examine enrollee characteristics associated with testing. METHODS We conducted a serial cross-sectional study of 505 440 initiations of MOUD from 2016 to 2019 among 361 537 Medicaid enrollees in 11 states. Measures of MOUD initiation; HIV, HBV, and HCV testing; comorbidities; and demographics were based on enrollment and claims data. Each state used Poisson regression to estimate associations between enrollee characteristics and testing prevalence within 90 days of MOUD initiation. We pooled state-level estimates to generate global estimates using random effects meta-analyses. RESULTS From 2016 to 2019, testing increased from 20% to 25% for HIV, from 22% to 25% for HBV, from 24% to 27% for HCV, and from 15% to 19% for all 3 conditions. Adjusted rates of testing for all 3 conditions were lower among enrollees who were male (vs nonpregnant females), living in a rural area (vs urban area), and initiating methadone or naltrexone (vs buprenorphine). Associations between enrollee characteristics and testing varied across states. CONCLUSIONS Among Medicaid enrollees in 11 US states who initiated medications for opioid use disorder, testing for human immunodeficiency virus, hepatitis B virus, hepatitis C virus, and all 3 conditions increased between 2016 and 2019 but the majority were not tested.

Abstract
OBJECTIVE To estimate the economic burden of non-communicable diseases (NCDs) in people living with HIV (PLWH) in Denmark. METHODS We conducted a cohort study using population-based Danish medical registries including all adult residents of the Central Denmark Region registered with a first-time HIV-diagnosis during the period 2006-2017. For each PLWH, we matched 10 persons without HIV from the background population by birth year, sex and municipality of residence. Information on healthcare utilization and costs for the PLWH and non-HIV cohorts was retrieved from register data. For each cohort, we estimated the annual costs for major disease categories (HIV care, other somatic care, and psychiatric care) in the period from 3 years before to 9 years after diagnosis/matching date. RESULTS We identified 407 PLWH and 4070 persons from the background population. The total healthcare costs during the study period were approximately three times higher for PLWH compared to the non-HIV cohort (€76 198 vs. €23 692). Average annual cost of hospital care, primary care and selected prescription medicine was estimated to be €6987 per year in the years after the diagnosis compared to €2083 per year in the non-HIV cohort. In PLWH, the cost of NCDs and psychiatric care was approximately two times higher than the cost of HIV care. CONCLUSION PLWH have higher healthcare costs stemming from three areas: excess cost due to the HIV infection, the treatment of NCDs, and psychiatric care.

Abstract
The present study sought to describe the use of generic drugs and single-tablet regimen (STR) de-simplification for the treatment of human immunodeficiency virus (HIV) infection among 41 hospitals from the cohort of the Spanish HIV/AIDS Research Network (CoRIS). In June 2018, we collected information on when generic antiretroviral drugs (ARVs) were introduced in the different hospitals, how the decisions to use them were made, and how the information was provided to the patients. Most of the nine available generic ARVs in Spain by June 2018 had been introduced in at least 85% of the participating hospitals, except for zidovudine (AZT)/lamivudine (3TC) and AZT. The time difference between the effective marketing date of each generic ARV and its first dispensing date in the hospitals was much shorter for the more recently approved generic ARV since the year 2017. However, only up to 20% of the hospitals de-simplified efavirenz (EFV)/tenofovir disoproxil (TDF)/emtricitabine (FTC), dolutegravir (DTG)/abacavir (ABC)/3TC, and rilpivirine (RPV)/TDF/FTC (to generic EFV+TDF/FTC, DTG+generic ABC/3TC, and RPV+generic TDF/FTC, respectively), whereas the generic STR EFV/TDF/FTC was introduced in 87.8% of the centers. The median times between the date of effective marketing of generic TDF/FTC and the date of de-simplification of EFV/TDF/FTC and RPV/TDF/FTC were 723 [interquartile range (IQR): 369-1,119] and 234 (IQR: 142-264) days, respectively; this time was 155 (IQR: 28-287) days for de-simplification of DTG/ABC/3TC. In conclusion, despite the widespread use of generic ARVs, STRs de-simplification was only undertaken in <20% of the hospitals. There was wide variability in the timing of the introduction of each generic ARV after they were available in the market.

Economic impact of generic antiretrovirals in France for HIV patients' care: a simulation between 2019 and 2023. BMC Health Serv Res 2022; 22:567. [PMID: 35477443 PMCID: PMC9044646 DOI: 10.1186/s12913-022-07859-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2021] [Accepted: 03/29/2022] [Indexed: 11/17/2022] Open
Abstract
Background In a context where the economic burden of HIV is increasing as HIV patients now have a close to normal lifespan, the availability of generic antiretrovirals commonly prescribed in 2017 and the imminence of patent expiration are expected to provide substantial savings in the coming years. This article aims to assess the economic impact of these generic antiretrovirals in France and specifically over a five-year period. Methods An agent-based model was developed to simulate patient trajectories and treatment use over a five-year period. By comparing the results of costs for trajectories simulated under different predefined scenarios, a budget impact model can be created and sensitivity analyses performed on several parameters of importance. Results The potential economic savings from 2019 to 2023 generated by generic antiretrovirals range from €309 million when the penetration rate of generics is set at 10% to €1.5 billion at 70%. These savings range from €984 million to €993 million as the delay between patent and generic marketing authorisation varies from 10 to 15 years, and from €965 million to €993 million as the Negotiated Price per Unit (NPU) of generics at market-entry varies from 40 to 50% of the NPU for patents. Discussion This economic savings simulation could help decision makers to anticipate resource allocations for further innovation in antiretrovirals therapies as well as prevention, especially by funding the Pre-Exposure Prophylaxis (PrEP) or HIV screening.

Abstract
A co-formulated, one pill once a day antiretroviral regimen (single-tablet regimen), containing efavirenz, emtricitabine, and tenofovir disoproxyl fumarate ( Atripla), revolutionized the antiretroviral therapy landscape. Single-tablet regimens provide not only dosing convenience but help optimize adherence and persistence with antiretroviral therapy to achieve durably suppressed viremia with both individual and societal benefits. Given the many excellent options available now, single-tablet regimens are the preferred choice for initiating antiretroviral therapy in almost all patients with rare exceptions for drug interactions and pregnancy, and for simplification of more complex antiretroviral therapy to a single-tablet regimen. In this special commemorative article, we celebrate this astounding advancement in antiretroviral therapy, championed by John C. Martin while CEO of Gilead Sciences, and its transformative impact on HIV care nationally and globally.

Abstract
HIV infection is now almost 40 years old. In this time, along with the catastrophe and tragedy that it has entailed, it has also represented the capacity of modern society to take on a challenge of this magnitude and to transform an almost uniformly lethal disease into a chronic illness, compatible with a practically normal personal and relationship life. This anniversary seemed an ideal moment to pause and reflect on the future of HIV infection, the challenges that remain to be addressed and the prospects for the immediate future. This reflection has to go beyond merely technical approaches, by specialized professionals, to also address social and ethical aspects. For this reason, the Health Sciences Foundation convened a group of experts in different aspects of this disease to discuss a series of questions that seemed pertinent to all those present. Each question was presented by one of the participants and discussed by the group. The document we offer is the result of this reflection.

Patients' experiences and opinions after de-simplification of their single-tablet regimens for the treatment of HIV infection: a survey in a multicentre cohort. J Acquir Immune Defic Syndr 2022; 90:62-68.

Abstract
OBJECTIVES The aims of this study were to describe patients' experiences after single-tablet regimen (STR) de-simplification, and its impact on self-reported treatment adherence and quality of life. METHODS We performed a survey among all patients from the multicenter cohort of the Spanish HIV/AIDS Network (CoRIS) who had de-simplified the STRs dolutegravir/abacavir/lamivudine (DGT/ABC/3TC) or rilpivirine/tenofovir disoproxil fumarate/emtricitabine (RPV/TDF/FTC) to their separate components (DTG+generic ABC/3TC or RPV+generic TDF/FTC, respectively) between December 2016 and November 2018. RESULTS Among 216 patients who fulfilled inclusion criteria, 138 (63.9%) completed the questionnaire. The majority (78.3%) knew what generic drugs are, only 8.7% thought that treatment with two pills is less effective than treatment with an STR, and 67.4% agreed that it is reasonable to take two pills instead of one for HIV treatment in order to decrease costs for the healthcare system.After de-simplification, 13.0% of the patients stated they had more secondary effects, 8.0% had forgotten one or more doses more frequently than before, and 10.9% had sometimes forgotten to take one pill, but not the other. A proportion of 30.4% reported not being happy to take more pills a day and 10.1% experienced a worse quality of life after the treatment de-simplification. CONCLUSIONS After STR de-simplification, most patients had a fair knowledge about generic antiretrovirals , and they agreed to de-simplify their STR in order to decrease costs. Although almost a third of the respondents were not happy to take two pills a day, only a minority reported worse adherence or quality of life.

Abstract
Objective To determine the costs of non-antiretroviral drugs and to identify the factors associated with their prescription in HIV-1 patients on antiretroviral therapy in Morocco. Methods Retrospective study of a cohort of 264 patients living with HIV-1 who were given antiretroviral therapy in the Venerology Dermatology Department at the Mohamed V Military Training Hospital of Rabat during the period from January 1st, 2014, December 31st, 2018. The costs retained were those of the hospital pharmacy for essential drugs, otherwise they were the costs in the private pharmacies. The logistic regression model was used to analyze the factors associated with prescription. Results Of the 264 patients included, the male predominance was 75%. The median age of patients was 49 [41-57]. At the onset, 21.2% of patients were already in the AIDS stage. After a mean duration of 11.1 ± 6.8 months of antiretroviral therapy, 71.6% of patients received at least one prescription for a non-antiretroviral drug. Over the entire follow-up period, the mean cost per patient was 24.2 €, and the mean cost supported per patient was 22.1 €. After cotrimoxazole (30.7% of patients), the most frequently prescribed drugs were iron (29.2% of patients), antibiotics (20.8% of patients), hypolipemics (20.1% of patients) and general antimycosics (16.3% of patients). Age (RR: 1.01; 95% CI: 1.00-1.07), AIDS stage (RR: 2.15; 95% CI: 1.61-4.19), anemia (RR: 2.02; 95% CI: 2.10-5.41) and number of comorbidities (RR: 2.45; 95% CI: 2.10-5.41) were significantly associated with the prescription of non-antiretroviral drugs. Conclusion Our work highlights the high frequency of prescription of non-antiretroviral drugs in patients living with HIV in Morocco; especially those who are older, anemic at the onset and those who are already at the AIDS stage.

Abstract
BACKGROUND The use of single-tablet regimens (STRs) in HIV treatment is ubiquitous. However, reintroducing the (generic) components as multi-tablet regimens (MTRs) could be an interesting cost-reducing strategy. It is essential to involve patient-reported outcome measures (PROs) to examine the effects of such an approach. Hence, this study compared PROs of people living with HIV taking an STR versus a MTR in a real world setting. MATERIALS AND METHODS This longitudinal study included 188 people living with HIV. 132 remained on a MTR and 56 switched to an STR. At baseline, months 1-3-6-12-18 and 24, participants filled in questionnaires on health-related quality of life (HRQoL), depressive symptoms, HIV symptoms, neurocognitive complaints (NCC), treatment satisfaction and adherence. Generalized linear mixed models and generalized estimation equations mixed models were built. RESULTS Clinical parameters and PROs of the two groups were comparable at baseline. Neurocognitive complaints and treatment satisfaction did differ over time among the groups. In the STR-group, the odds of having NCC increased monthly by 4,1% as compared to the MTR-group (p = 0.035). Moreover, people taking an STR were more satisfied with their treatment after 6 months: the median change score was high: 24 (IQR 7,5-29). Further, treatment satisfaction showed a contrary evolution in the groups: the estimated state score of the STR-group increased by 3,3 while it decreased by 0,2 in the MTR-group (p = 0.003). No differences over time between the groups were observed with regard to HRQoL, HIV symptoms, depressive symptoms and adherence. CONCLUSIONS Neurocognitive complaints were more frequently reported among people on an STR versus MTR. This finding contrasts with the higher treatment satisfaction in the STR-group over time. The long-term effects of both PROs should guide the decision-making on STRs vs. (generic) MTRs.

Cost-savings and potential cost-savings through the distribution of generic antiretroviral drugs within the statutory health insurance market of Germany between January 2017 and June 2019. BMC Health Serv Res 2022; 22:63. [PMID: 35027062 PMCID: PMC8756633 DOI: 10.1186/s12913-021-07390-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2021] [Accepted: 12/07/2021] [Indexed: 11/10/2022] Open
Abstract
Abstract Background Recent patent losses for antiretroviral drugs (ARV) have led to the debate of cost-saving through the replacement of patented drugs with generic drugs. The split of recommended single-tablet regimens (STR) into their single substance partners is one of the considerations mentioned in said debate. Particularly, generic tenofovir disoproxil/emtricitabine (TDF/FTC) is expected to hold untapped cost-saving potential, which may curb increasing overall expenditures for combined antiretroviral therapy (cART) within the statutory health insurance (SHI) of Germany. Methods Data of ARV reimbursed by the SHI were used to describe the trends of defined daily doses (DDD) as well as the revenue within the German ARV market. They were also used to determine the cost-savings of moving to generic drugs. The time period observed was between January 2017 and June 2019. The potential cost-savings were determined with following assumption in mind: the maximum possible use of generic ARV, including 1) the split of STR and replacing all substance partners with generic ones, and 2) replacing patented tenofovir alafenamide/emtricitabine (TAF/FTC) with generic TDF/FTC. Results Throughout the observation period, the DDD of generic ARV increased nearly five-fold while their revenue increased more than four-fold. Total cost-saving showed a sharp increase over the same period, with generic TDF/FTC accounting for a share of around 70%. The largest potential cost-saving could have been achieved through replacing patented TAF/FTC with generic TDF/FTC, peaking at nearly 10% of total revenue, but showing decreasing trends in general. Conclusion The progressive distribution of generic ARV ensured increasing cost-savings, but consequently curbed the potential cost-savings. Unique price reductions of generic TDF/FTC have played a pivotal role for these effects. In any case, substituting with generic ARV should not fail to adhere to the treatment guidelines and continue to consider the medical requirements for the treatment.

Abstract
The emergence of dual therapy for antiretroviral (ARV)-experienced persons living with HIV (PWH) offers the opportunity to reduce lifetime exposure to unnecessary ARV drugs while maintaining viral suppression and reducing the cost of care. Our objective, using retrospective analysis of a quality care initiative, was to examine in routine clinical practice the clinical impact of switching PWH stable on a three-drug to a two-drug single-tablet formulation (STF) ARV regimen. We also examined the cost implications of this STF adjustment. Between January 1, 2020 and January 1, 2021 eligible patients (i.e., virally suppressed, no active hepatitis B infection, no documented nucleoside reverse transcriptase inhibitors/integrase strand transfer inhibitor resistance) were offered, on a convenience basis and as part of routine care, the opportunity to adjust their current three-drug STF to a two-drug STF (dolutegarvair/lamivudine). The acceptance, clinical efficacy, safety, tolerability, and cost of treatment were measured for patients who switched in 2020. Of 989 eligible PWH, 408 were approached and 391 (39.5%) switched to two-drug regimen; 99% remained on the two-drug STF at year's end (median 240 days follow-up). Only 2/391 patients who switched lost viral control. The total ARV drug cost for all 989 patients decreased by 10.3% generating an actual savings of $1,596,666 among patients approached and switched in 2020. Patient interest and uptake in switching to two-drug STF was substantial and resulted in few discontinuations for any reason. It provided significant and immediate cost savings within the first year. Our results bring clarity to discussions on whether using two-drug regimens would be practical and acceptable in nonclinical trial settings.

Abstract
INTRODUCTION We aimed to assess the effectiveness and tolerability of dolutegravir (DTG), abacavir (ABC) and lamivudine (3TC) administered as branded STR (DTG/ABC/3TC) or as two separate pills (DTG and either branded ABC/3TC [DTG+(ABC/3TC)b] or generic ABC/3TC [DTG+(ABC/3TC)g]). METHODS We included individuals from the multicentre cohort of the Spanish HIV/AIDS Research Network (CoRIS) who received DTG/ABC/3TC, DTG+(ABC/3TC)b or DTG+(ABC/3TC)g during 2015 to 2018. We used multivariable logistic regression to compare the proportion of antiretroviral-naïve individuals who achieved viral suppression (VS) (viral load ≤50 copies/mL) at 24 weeks of initiating with DTG+(ABC/3TC)b or DTG+(ABC/3TC)g versus DTG/ABC/3TC. We also calculated the proportion of virologically suppressed individuals who maintained VS at 24 weeks after switching from DTG/ABC/3TC to DTG+(ABC/3TC)g. RESULTS During the study period, 829, 68 and 47 treatment-naïve individuals started treatment with DTG/ABC/3TC, DTG+(ABC/3TC)b or DTG+(ABC/3TC)g respectively. The proportions of individuals who changed their regimens due to side effects during the first 24 weeks were 3.7%, 4.4% and 6.4% respectively (p = 0.646). We did not find significant differences in VS at 24 weeks among individuals starting with DTG+(ABC/3TC)b or DTG+(ABC/3TC)g compared to those initiating with DTG/ABC/3TC. Among 177 virologically suppressed individuals who switched from DTG/ABC/3TC to DTG+(ABC/3TC)g, 170 (96.0%) maintained VS at 24 weeks. CONCLUSIONS In naïve individuals, the effectiveness and tolerability at 24 weeks of DTG plus ABC/3TC administered as two separate pills, either as branded or generic ABC/3TC, was similar to the STR DTG/ABC/3TC. Switching the STR DTG/ABC/3TC to its separate components DTG+(ABC/3TC)g in virologically suppressed individuals did not seem to impair its effectiveness.

Abstract
BACKGROUND: Dolutegravir(DTG)/lamivudine(3TC) is the first 2-drug regimen recommended as an initial treatment for people living with HIV (PLHIV). OBJECTIVE: To assess the cost-effectiveness and potential budget impact of DTG/3TC in the US healthcare setting. METHODS: A previously published hybrid decision-tree and Markov cohort state transition model was adapted to estimate the incremental costs and health outcome benefits over a patients' lifetime. DTG/3TC was compared with current standard of care in treatment naive and treatment experienced virologically suppressed PLHIV. Health states included in the model were based upon virologic response and CD4 cell count, with death as an absorbing state. Clinical data was informed by the Phase III GEMINI 1 and 2 clinical trials, a published network meta-analysis (NMA) in treatment-naive patients and the Phase III TANGO clinical trial in treatment experienced patients. Costs and utilities were informed by published data and discounted annually at a rate of 3%. A separate 5-year budget impact analysis was conducted assuming 5%-15% uptake in eligible treatment naive and 10%-30% uptake in eligible treatment experienced patients. RESULTS: In the treatment naive analyses based on GEMINI 1 and 2, DTG/3TC dominated, i.e., was less costly and more effective, than all comparators. DTG/3TC resulted in 0.083 incremental quality-adjusted life-years (QALYs) at a cost saving of $199,166 compared with the DTG + tenofovir disoproxil(TDF)/emtricitabine(FTC) comparator arm. The incremental QALY and cost savings for DTG/3TC compared with DTG/abacavir(ABC)/3TC, cobicistat-boosted darunavir(DRV/c)/tenofovir alafenamide(TAF)/FTC, and bictegravir (BIC)/TAF/FTC, based on NMA results were 0.465, 0.142, and 0.698, and $42,948, $122,846, and $44,962, respectively. In the analyses of treatment-experienced virologically suppressed patients based on TANGO, DTG/3TC offered slightly lower QALYs (-0.037) with an estimated savings of $78,730 when compared with continuation of TAF-based regimen (TBR). Sensitivity analyses demonstrated that these conclusions were relatively insensitive to alternative parameter estimates. The budget impact analysis estimated that by 5th year a total of 70,240 treatment naive patients and 1,340,480 treatment experienced patients could be eligible to be prescribed DTG/3TC. The estimated budget savings over 5 years ranged from $1.12b to $3.35b (corresponding to 27,512 to 82,536 on DTG/3TC by year 5) in the lowest and highest uptake scenarios, respectively. CONCLUSION: In conclusion, DTG/3TC with its comparable efficacy and lower drug acquisition costs, has the potential to offer significant cost savings to US healthcare payers for the initial treatment of treatment naive patients and as a treatment switching option for virologically suppressed patients.

Abstract
OBJECTIVES To assess the attitudes and opinions about generic antiretroviral drugs (ARVs) and single-tablet regimen (STR) de-simplification among physicians prescribing HIV treatment in the cohort of the Spanish HIV/AIDS Research Network (CoRIS). METHODS An online questionnaire with 27 structured questions was sent to all physicians (n=199) who prescribed ARVs among the 45 centres participating in the cohort. RESULTS A total of 169 (84.9%) physicians answered the questionnaire. Only 4.1% of the physicians would never prescribe generic ARVs, but 53.3% would not prescribe them if the number of pills per day increased and 89.3% would not prescribe them if the number of doses per day increased. However, 84.0% of the physicians agreed to prescribe generic ARVs if doing so would decrease costs for the public healthcare system. The percentages of physicians stating that generic ARVs (compared with branded ones) would be associated with worse adherence, more adverse effects or more probability of virological failure, provided that the number of pills and doses per day would not change, were low: 0.6%, 7.7% and 3.6%, respectively. However, these percentages were much higher if the generic ARV entailed breaking an STR: 63.9%, 18.9% and 42.0%, respectively. Most physicians stated that they needed more information about the effectiveness and safety of generic ARVs and the price difference compared with their branded equivalents. CONCLUSIONS Although most physicians were confident about prescribing generic ARVs, the majority had strong concerns about de-simplifying STR, and they also needed more information about generic drugs.

Abstract
BACKGROUND Lifetime cost estimates are a useful tool in measuring the economic burden of HIV in the United States. Previous estimation methods need to be updated, given improving antiretroviral therapy regimens and updated costs. METHODS We used an updated version of the agent-based model progression and transmission of HIV (PATH) 3.0 to reflect current regimens and costs. We simulated a cohort of those infected in 2015 until the last person had died to track the lifetime costs for treatment of HIV, including HIV health care utilization costs (inpatient, outpatient, opportunistic infection prophylaxis, non-HIV medication, and emergency department), opportunistic infection treatment costs, and testing costs. We assumed a median per-person diagnosis delay of 3 years and a 3% base monthly probability of dropout from care for a base-case scenario. Additionally, we modeled a most favorable scenario (median diagnosis delay of 1 year and 1% base dropout rate) and a least favorable scenario (median diagnosis delay of 5 years and 5% base dropout rate). RESULTS We estimated an average lifetime HIV-related medical cost for a person with HIV of $420,285 (2019 US$) discounted (3%) and $1,079,999 undiscounted for a median 3-year diagnosis delay and 3% base dropout rate. Our discounted cost estimate was $490,045 in our most favorable scenario and $326,411 in our least favorable scenario. CONCLUSIONS Lifetime per-person HIV-related medical costs depend on the time from infection to diagnosis and the likelihood of dropping out of care. Our results, which are similar to previous studies, reflect updated antiretroviral therapy regimens and costs for HIV treatment.

Abstract
INTRODUCTION The use of lifelong antiretroviral therapy (ART) results in increased costs of care; the ability to finance and control sustained costs of ART needs to be discussed. APPROACH The Southern Alberta Clinic initiated a practical cost savings approach that switched select patients from a branded ART to a less expensive generic variation. Our approach surveyed physicians and patients on their acceptance of switching and then launched a program asking patients if they would switch to generic variations for cost control purposes. RESULTS Our early findings found >50% of patients approached agreed to switch. We found no evidence of increased risk of viral breakthrough, resistance, side effects, or displeasure with generic drugs. Measured cost savings in the first year were >$1.1 million with annual projected savings of between $4.3 million and $2.6 million (in 2017 Cdn$). CONCLUSION Our approach can provide an option for controlling costs of HIV care without compromising quality.

Abstract
Introduction: There are positive aspects regarding the prescribing of fixed dose combinations (FDCs) versus prescribing the medicines separately. However, these have to be balanced against concerns including increased costs and their irrationality in some cases. Consequently, there is a need to review their value among lower- and middle-income countries (LMICs) which have the greatest prevalence of both infectious and noninfectious diseases and issues of affordability.Areas covered: Review of potential advantages, disadvantages, cost-effectiveness, and availability of FDCs in high priority disease areas in LMICs and possible initiatives to enhance the prescribing of valued FDCs and limit their use where there are concerns with their value.Expert commentary: FDCs are valued across LMICs. Advantages include potentially improved response rates, reduced adverse reactions, increased adherence rates, and reduced costs. Concerns include increased chances of drug:drug interactions, reduced effectiveness, potential for imprecise diagnoses and higher unjustified prices. Overall certain FDCs including those for malaria, tuberculosis, and hypertension are valued and listed in the country's essential medicine lists, with initiatives needed to enhance their prescribing where currently low prescribing rates. Proposed initiatives include robust clinical and economic data to address the current paucity of pharmacoeconomic data. Irrational FDCs persists in some countries which are being addressed.

Abstract
BACKGROUND We projected the clinical outcomes, cost-effectiveness, and budget impact of ibalizumab plus an optimized background regimen (OBR) for people with multidrug-resistant (MDR) HIV in the United States. METHODS Using the Cost-Effectiveness of Preventing AIDS Complications microsimulation model and a health care sector perspective, we compared 2 treatment strategies for MDR HIV: (1) IBA + OBR-ibalizumab plus OBR and (2) OBR-OBR alone. Ibalizumab efficacy and cohort characteristics were from trial data: mean age 49 years, 85% male, and mean CD4 150/µL. Six-month viral suppression was 50% with IBA + OBR and 0% with OBR. The ibalizumab loading dose cost $10,500, and subsequent ibalizumab injections cost $8400/month; OBR cost $4500/month. Incremental cost-effectiveness ratios (ICERs) were calculated using discounted (3%/year) quality-adjusted life years (QALYs) and costs. ICERs ≤$100,000/QALY were considered cost-effective. We performed sensitivity analysis on key parameters and examined budget impact. RESULTS In the base case, 5-year survival increased from 38% with OBR to 47% with IBA + OBR. Lifetime costs were $301,700/person with OBR and $661,800/person with IBA + OBR; the ICER for IBA + OBR compared with OBR was $260,900/QALY. IBA + OBR was not cost-effective even with 100% efficacy. IBA + OBR became cost-effective at base case efficacy if ibalizumab cost was reduced by ≥88%. For an estimated 12,000 people with MDR HIV in the United States, IBA + OBR increased care costs by $1.8 billion (1.5% of total treatment budget) over 5 years. CONCLUSIONS For people with MDR HIV lacking other treatment options, ibalizumab will substantially increase survival when effective. Although adding ibalizumab to OBR is not cost-effective, the low number of eligible patients in the United States makes the budget impact relatively small.

Abstract
BACKGROUND As life expectancy of patients infected with human immunodeficiency virus (HIV) approaches that of the general population, the composition of HIV management costs is likely to change. OBJECTIVES To (a) review treatment and disease management costs in HIV, including costs of adverse events (AEs) related to antiretroviral therapy (ART) and long-term toxicities, and (b) explore the evolving cost drivers. METHODS A targeted literature review between January 2012 and November 2017 was conducted using PubMed and major conferences. Articles reporting U.S. costs of HIV management, acquired immunodeficiency syndrome (AIDS)-defining events, end of life care, and ART-associated comorbidities such as cardiovascular disease (CVD), chronic kidney disease (CKD), and osteoporosis were included. All costs were inflated to 2017 U.S. dollars. A Markov model-based analysis was conducted to estimate the effect of increased life expectancy on costs associated with HIV treatment and management. RESULTS 22 studies describing HIV costs in the United States were identified, comprising 16 cost-effectiveness analysis studies, 5 retrospective analyses of health care utilization, and 1 cost analysis in a resource-limited setting. Management costs per patient per month, including routine care costs (on/off ART), non-HIV medication, opportunistic infection prophylaxis, inpatient utilization, outpatient utilization, and emergency department utilization were reported as CD4+ cell-based health state costs ranging from $1,192 for patients with CD4 > 500 cells/mm3 to $2,873 for patients with CD4 < 50 cells/mm3. Event costs for AEs ranged from $0 for headache, pain, vomiting, and lipodystrophy to $31,545 for myocardial infarction. The mean monthly per-patient costs for CVD management, CKD management, and osteoporosis were $5,898, $6,108, and $4,365, respectively. Improvements in life expectancy, approaching that of the general population in 2018, are projected to increase ART-related and AE costs by 35.4% and comorbidity costs by 175.8% compared with estimated costs with HIV life expectancy observed in 1996. CONCLUSIONS This study identified and summarized holistic cost estimates appropriate for use within U.S. HIV cost-effectiveness analyses and demonstrates an increasing contribution of comorbidity outcomes, primarily associated with aging in addition to long-term treatment with ART, not typically evaluated in contemporary HIV cost-effectiveness analyses.

Abstract
Significant advances in the potency and tolerability of antiretroviral therapy (ART) have led to very high rates of virologic success for most who remain adherent to therapy. As a result, the life expectancy of people living with HIV (PLWH) has increased significantly. PLWH do, however, continue to experience a significantly higher risk of noninfectious comorbidities and chronic age-related complications, including cardiovascular disease and malignancies, which are now the biggest drivers of this excess morbidity and mortality. Therefore, in addition to virologic failure, the management of the treatment-experienced patient increasingly requires optimization of ART to enhance tolerability, avoid drug-drug interactions, and mitigate non-AIDS complications and comorbid conditions. This article will present principles of the management of virologic failure, poor immunologic recovery, and strategies for optimizing ART in the setting of virologic suppression.

Abstract
BACKGROUND Highly active antiretroviral therapy (HAART) is provided free of charge to all human immunodeficiency virus (HIV) positive residents in Italy. As fixed dose coformulations (FDCs) are often more expensive in comparison to the same drugs administered separately in a multi-tablet regimen (MTR), we considered a cost-effective strategy involving patients in the switch from their FDCs to corresponding MTRs including generic antiretrovirals.
AIM To verify if this would affect the virological and immunological response in comparison to maintaining the FDC regimens.
METHODS From January 2012 to December 2013, we assessed the eligibility of all the HIV-1 positive adults on stable HAART being treated at our hospital-based outpatient clinic in Treviso, Italy. Participants who accepted to switch from their FDC regimen to the corresponding MTR joined the MTR group, while those who maintained a FDC regimen joined the FDC group. Clinical data, including changes in HAART regimens, respective reasons why and adverse effects, were recorded at baseline and at follow-up visits occurring at weeks 24, 48 and 96. All participants were assessed for virological and immunological responses at baseline and at weeks 24, 48 and 96.
RESULTS Two hundred and forty-three eligible HIV-1 adults on HAART were enrolled: 163 (67%) accepted to switch to a MTR, joining the MTR group, while 80 (33%) maintained their FDCs, joining the FDC group. In a parallel analysis, there were no significant differences in linear trend of distribution of HIV-RNA levels between the two groups and there were no significant odds in favour of a higher level of HIV-RNA in either group at any follow-up and on the overall three strata analysis. In a before-after analysis, both FDC and MTR groups presented no significant differences in distribution of HIV-RNA levels at either weeks 48 vs 24 and weeks 96 vs 24 cross tabulations. A steady increase of mean CD4 count was observed in the MTR group only, while in the FDC group we observed a slight decrease (-23 cells per mmc) between weeks 24 and 48.
CONCLUSION Involving patients in the switch from their FDC regimens to the corresponding MTRs for economic reasons did not affect the effectiveness of antiretroviral therapy in terms of virological response and immunological recovery

Abstract
There is paucity of evidence on cost of antiretroviral therapy (ART) delivered through the public sector in India. Moreover, the Government of India is considering changing the criteria for introduction of ART to HIV patients, which is likely to have significant economic implications. In this paper, we assess the health system cost of ART services at two levels of health care delivery. Bottom-up costing was used to collect data on capital and recurrent resources consumed over a period of one year (April 2014–March 2015). Capital costs were annualized and shared costs apportioned to calculate annual and unit costs of providing ART care. Sensitivity analysis was undertaken to measure the extent of uncertainty in input prices. The annual per capita cost of ART therapy was INR 48,975 (USD738) in the Centre of Excellence (COE) and INR 24,954 (USD376) in the ART centre. Drugs contributed around 70% and 65% of total annual cost, followed by human resource (19% each) and capital cost (7%; 12%) in COE and ART centres, respectively. These provide a comprehensive assessment of the cost of ART care in India. The study estimates could be used for planning of services, as well as undertaking further cost-effectiveness studies.

Abstract
INTRODUCTION Although antiretroviral therapy is highly effective, many patients may benefit from switching strategies. Rapid advances in the development of new antiretroviral drugs could enhance the success of these approaches. In this review, we build on a previous review from 2014 and summarize the current options for switching strategies in virologically suppressed HIV-infected patients. Areas covered: We conduct a critical analysis of scientific evidence for various switching strategies used in the modern era of antiretroviral therapy, as well as reasons for these approaches, other considerations to be taken into account, and alternative strategies. Expert opinion: Current antiretroviral regimens are effective and well tolerated in HIV patients. A number of options may provide benefit to patients, even virologically suppressed patients, possibly enhancing adherence and avoiding adverse effects and toxicities. Cost reduction may also be an important goal of switching strategies. The present scenario is excellent, as many good antiretroviral compounds and regimens allow clinicians to further improve on effective treatments now used in routine practice. Even the current paradigm of triple-drug regimens as the standard of care could change, at least in some patients.

Abstract
OBJECTIVES As more HIV-positive individuals receive antiretroviral therapy (ART), payers are seeking options for covering these increased and sustained drug costs. Strategic use of available generic antiretroviral (ARV) formulations may be feasible. De-simplifying a single-tablet co-formulation (STF) into two or more tablets using both brand and generic drugs has been proposed. We determine if voluntary de-simplification of one STF could be utilized as a cost-saving strategy. We report on the challenges, uptake, outcomes and cost savings of this initiative. METHODS Patients stable on the most commonly used STF (Triumeq® ) were offered the option of remaining on Triumeq® or switching to generic abacavir/lamivudine and Tivicay® between 1 January 2015 and 1 January 2018; those starting ART consisting of abacavir/lamivudine/doulutegravir in the same period were offered the option of starting Triumeq® or generic abacavir/laminvudine and Tivicay® . No incentives were provided. We examined the acceptance/decline rates, patient satisfaction, health care outcomes and annual cost savings. RESULTS Of 626 patients receiving Triumeq® , 321 were approached; 177 (55.1%) agreed to de-simplify. Of patients initiating ART, 62.7% chose the generic co-formulation. Patients switching to or starting on the generic co-formulation were more likely to be male, > 45 years old, Caucasian, men who have sex with men (MSM) and more HIV-experienced, and to have more comorbidities (all P < 0.05). Preference for STF was cited for declining de-simplification. No concern about generic ARVs was expressed. The rate of viral load > 500 HIV-1 RNA copies/mL after baseline was 2.7% in switched patients compared with 7.0% in those declining to switch. No de novo resistance occurred. A saving of Cdn$1 319 686 was achieved in the first year. CONCLUSIONS Reliance on altruism, while respecting patient autonomy, achieved de-simplification in > 50% of patients approached, and generated immediate cost savings with no increased risk of adverse events, viral breakthrough or resistance.

Abstract
Background Single-tablet regimens are preferred prescription choices for HIV treatment, but there are limited outcomes data comparing single-tablet regimens to multiple-tablet regimens. Methods We retrospectively assessed treatment-naïve patients at a single urban HIV clinic in the United States for viral load suppression at 6 and 12 months after initiating either single-tablet or multiple-tablet regimens. Multivariate regression was performed to obtain relative risks and adjust for potential confounders. Results Of 218 patients, 47% were on single-tablet regimens and 53% on multiple-tablet regimens; 77% of single-tablet regimen patients had undetectable viral load at 6 months compared to 61% of multiple-tablet regimen patients (p = 0.012). At 12 months, 82% on single-tablet regimens and 66% on multiple-tablet regimens (p = 0.019) had undetectable viral load. Relative risk of any detectable viral load was 1.6 (95% confidence interval: 1.1-2.5) for patients on multiple-tablet regimens compared to single-tablet regimens at 6 months, and 2.2 (95% confidence interval: 1.2-4.0) at 12 months. Conclusion Single-tablet regimens may provide better virologic control than multiple-tablet regimens in urban HIV-infected persons.

Abstract
OBJECTIVES To compare outcomes with single tablet regimens (STR) versus multi-tablet regimens (MTR) for human immunodeficiency virus (HIV) treatment using published data. DESIGN Systematic review and random-effects meta-analysis of literature on approved and investigational HIV regimens. METHODS The research followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Single or un-blinded studies reporting a direct comparison between STR and MTR were eligible for the meta-analysis. Double-blinded studies were excluded due to lack of difference in pill burden between cohorts. The key outcomes of interest included: adherence rates/proportion meeting target, efficacy, safety/tolerability, non-clinical and economic outcomes. RESULTS After screening 63 full-text articles and posters, 14 studies were eligible for the meta-analysis. The analysis showed that patients taking STR had improved outcomes over those taking MTR. Patients were significantly more adherent regardless of daily dosing frequency (odds ratio [OR]: 1.96, p < 0.001) and were more likely to achieve virological suppression (relative risk [RR]: 1.05, p = 0.002). There was a trend toward a lower discontinuation risk in the STR cohort, together with reported higher therapy satisfaction, better symptom control, improved health status, reduced healthcare resource utilization and demonstrated cost-effectiveness compared to MTR. There were no differences in CD4 cell count increase (at 48 weeks) or safety outcomes. CONCLUSIONS The findings of this study confirm previously reported preliminary findings of the advantages of STR over MTR for HIV treatment in adherence, therapy continuation, viral suppression, tolerability, quality of life improvement, cost-effectiveness and healthcare resource utilization.

Abstract
When Dr. Hortense screens her patients in Chicago for cervical dysplasia and cancer, she conducts a pelvic exam, takes a sample of cervical cells, and sends them for Pap cytology and human papilloma virus DNA co-testing. But when she conducts cervical cancer screening in Botswana, she employs a much simpler diagnostic strategy. She applies acetic acid to highlight precancerous lesions and visually inspects the cervix-a technique known as the VIA (visual inspection with acetic acid) method. She treats suspicious lesions with cryotherapy. There are multiple reasons that Dr. Hortense uses VIA in developing countries. It requires no specialized laboratory facilities or highly trained personnel. With immediate results, there is no delay in diagnosis and treatment, ensuring that patients are not lost to follow-up. Most importantly, VIA is considerably cheaper than Pap and HPV co-testing. This difference in care between Chicago and Botswana presents an ethical dilemma in global health: is it ethically acceptable to provide some patients cheaper treatments that are less effective or more toxic than the treatments other patients receive? We argue that it is ethical to consider local resource constraints when deciding what interventions to provide. The provision of cheaper, less effective health care is frequently the most effective way of promoting health and realizing the ethical values of utility, equality, and priority to the worst off.

Abstract
This study evaluated the effectiveness of formulary substitution from products or regimens containing name brand emtricitabine to alternative regimens containing generic lamivudine among virologically suppressed HIV-infected patients in a correctional managed health care system. Results of this retrospective cohort study showed that 94.9% of patients switched from emtricitabine to lamivudine ( n = 447) and 93.0% of emtricitabine control patients ( n = 449) had an undetectable viral load at last available test over a 2-year period. The two groups also showed similar values for CD4 counts, compliance, discontinuation, and M184V mutation; however, a slightly greater proportion of lamivudine patients experienced respiratory symptoms. Nonetheless, this study demonstrates that switching virologically suppressed HIV-infected patients from name brand emtricitabine-containing regimens to generic lamivudine-based regimens may reduce costs without compromising safety or effectiveness in correctional managed health care systems with directly observed therapy.

How has the cost of antiretroviral therapy changed over the years? A database analysis in Italy. BMC Health Serv Res 2018; 18:691.

Abstract
Background The number of human immunodeficiency virus (HIV)-related hospitalizations has decreased worldwide in recent years, due to the availability of combined antiretroviral therapies (cART). The present analysis aimed to analyse the economic, and clinical burden of HIV management, after the introduction of systematic use of cART. Methods Data from HIV-infected patients, treated at Policlinico San Martino Hospital in Genova (Italy) were retrospectively collected. A comparison between years 2009 and 2015 was performed. HIV-related admissions were identified by using the Diagnosis-Related Group (DRG) codes. The resource consumption of outpatient services was derived by using a modelling approach. Expenditure for drugs was also analysed, as aggregate data. Results The number of HIV-infected patients was 898 in 2009 and 1006 in 2015. Overall, the virological success rate improved from 2009 to 2015, as the percentage of patients with HIV-RNA < 50 copies/mL increased from 79 to 89% (P < 0.05). The average incidence of hospitalizations per-patient decreased from 0.30 in 2009, to 0.13 in 2015. Average expenditure per-patient decreased from €10,107 in 2009 to €9063 in 2015. Conclusions The present analysis confirmed the role of cART in controlling HIV viral load and, consequently, in reducing hospitalizations, admissions to day-hospital and the use of outpatient services. Clinical improvements and economic savings more than compensated the investments required to treat HIV-infected patients with cART. Health Authorities should invest in modern cART supply and universal treatment, to use at best the available resources and obtain a cost-effective improvement of health in people living with HIV. Additional research, with the involvement of different centers and the use of patient-specific data, are recommended to consolidate the findings of this analysis.

Abstract
Importance Antiretroviral therapy (ART) is the cornerstone of prevention and management of HIV infection. Objective To evaluate new data and treatments and incorporate this information into updated recommendations for initiating therapy, monitoring individuals starting therapy, changing regimens, and preventing HIV infection for individuals at risk. Evidence Review New evidence collected since the International Antiviral Society-USA 2016 recommendations via monthly PubMed and EMBASE literature searches up to April 2018; data presented at peer-reviewed scientific conferences. A volunteer panel of experts in HIV research and patient care considered these data and updated previous recommendations. Findings ART is recommended for virtually all HIV-infected individuals, as soon as possible after HIV diagnosis. Immediate initiation (eg, rapid start), if clinically appropriate, requires adequate staffing, specialized services, and careful selection of medical therapy. An integrase strand transfer inhibitor (InSTI) plus 2 nucleoside reverse transcriptase inhibitors (NRTIs) is generally recommended for initial therapy, with unique patient circumstances (eg, concomitant diseases and conditions, potential for pregnancy, cost) guiding the treatment choice. CD4 cell count, HIV RNA level, genotype, and other laboratory tests for general health and co-infections are recommended at specified points before and during ART. If a regimen switch is indicated, treatment history, tolerability, adherence, and drug resistance history should first be assessed; 2 or 3 active drugs are recommended for a new regimen. HIV testing is recommended at least once for anyone who has ever been sexually active and more often for individuals at ongoing risk for infection. Preexposure prophylaxis with tenofovir disoproxil fumarate/emtricitabine and appropriate monitoring is recommended for individuals at risk for HIV. Conclusions and Relevance Advances in HIV prevention and treatment with antiretroviral drugs continue to improve clinical management and outcomes for individuals at risk for and living with HIV.

Abstract
Adherence to antiretroviral (ARV) is crucial to achieve viral load suppression in HIV-infected patients. This study aimed to compare adherence to generic multi-tablet regimens (MTR) vs. brand MTR likely to incorporate ARV drugs without breaking fixed-dose combinations (FDC) and brand single-tablet regimens (STR) likely to incorporate generics by breaking the FDC. Patients aged of 18 years or over exposed to one of the generic or the brand of lamivudine (3TC), zidovudine/lamivudine (AZT/TC), nevirapine (NVP), or efavirenz (EFV), or the brand STR of efavirenz/emtricitabine/tenofovir (EFV/FTC/TDF). Adherence was measured by medication possession ratio (MPR) using both defined daily dose (DDD) and daily number of tablet recommended for adults (DNT). Adherence to generic MTR vs. brand MTR and brand STR was compared using Kruskal-Wallis. The overall median adherence was 0.97 (IQR 0.13) by DNT method and 0.97 (0.14) by DDD method. Adherence in patients exposed to generic MTR (n = 165) vs. brand MTR (n = 481) and brand STR (n = 470) was comparable by DNT and DDD methods. In conclusion, adherence to generic MTR was high and comparable with adherence to brand MTR and to STR. Utilization of DDD instead DNT to measure the MPR led to small but nonsignificant difference that has no clinical impact.

Abstract
Newer HIV regimens are typically taken once daily but vary in the number of pills required. Whether the number of pills in a once-daily HIV regimen affects clinical outcomes is unknown. We retrospectively compared adherence, retention in care, and virologic outcomes between patients starting a once daily single-tablet regimen (STR) to patients starting a once-daily multi-tablet regimen (MTR) in a publicly funded clinic in the United States. Outcomes were measured in the year after starting ART and included retention in care, virologic suppression, and medication possession ratio of at least 80%. Data from patients initiating therapy from 1 January 2008 to 31 December 2011 were analyzed with both unadjusted and propensity-score adjusted regression. Overall, 622 patients started with an STR (100% efavirenz-based) and 406 with an MTR (65% atazanavir-based and 35% darunavir-based) regimen. Retention in care was achieved in 80.7% of STR patients vs. 72.7% of MTR patients (unadjusted OR 1.57, 95% CI 1.17-2.11; adjusted OR 1.49, 95% CI 1.10-2.02). Virologic suppression occurred among 84.4% of STR patients vs. 77.6% of MTR patients (unadjusted OR 1.56; 95% CI 1.14-2.15; adjusted OR 1.41; 95% CI 1.02-1.96). There was no difference in the proportion of patients achieving at least 80% adherence, as measured by medication possession ratio (33.0% of STR patients and 30.1% of MTR patients; unadjusted OR 1.14; 95% CI 0.87-1.50; adjusted OR 1.04, CI 0.79-1.38). While it is difficult to eliminate confounding in this observational study, retention in care and virologic outcomes were better in patients prescribed STRs.

Abstract
OBJECTIVES The incremental costs of expanding antiretroviral (ARV) drug treatment to all HIV-infected patients are substantial, so cost-saving initiatives are important. Our objectives were to determine the acceptability and financial impact of de-simplifying (i.e. switching) more expensive single-tablet formulations (STFs) to less expensive generic-based multi-tablet components. We determined physician and patient perceptions and acceptance of STF de-simplification within the context of a publicly funded ARV budget. METHODS Programme costs were calculated for patients on ARVs followed at the Southern Alberta Clinic, Canada during 2016 (Cdn$). We focused on patients receiving Triumeq® and determined the savings if patients de-simplified to eligible generic co-formulations. We surveyed all prescribing physicians and a convenience sample of patients taking Triumeq® to see if, for budgetary purposes, they felt that de-simplification would be acceptable. RESULTS Of 1780 patients receiving ARVs, 62% (n = 1038) were on STF; 58% (n = 607) of patients on STF were on Triumeq®. The total annual cost of ARVs was $26 222 760. The cost for Triumeq® was $8 292 600. If every patient on Triumeq® switched to generic abacavir/lamivudine and Tivicay® (dolutegravir), total costs would decrease by $4 325 040. All physicians (n = 13) felt that de-simplifying could be safely achieved. Forty-eight per cent of 221 patients surveyed were agreeable to de-simplifying for altruistic reasons, 27% said no, and 25% said maybe. CONCLUSIONS De-simplifying Triumeq® generates large cost savings. Additional savings could be achieved by de-simplifying other STFs. Both physicians and patients agreed that selective de-simplification was acceptable; however, it may not be acceptable to every patient. Monitoring the medical and cost impacts of de-simplification strategies seems warranted.

Utilization and costs of HIV antiretroviral drugs in Europe during the last ten years: Impact of generic antiretroviral drugs on cost reduction. Health Policy 2018; 122:237-242. [PMID: 29398158 DOI: 10.1016/j.healthpol.2018.01.002] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2017] [Revised: 11/24/2017] [Accepted: 01/04/2018] [Indexed: 12/19/2022]
Abstract
INTRODUCTION Simulation studies showed that generic antiretroviral (ARV) drug utilization could lead to significant cost reduction of HIV treatment in developed world. This study aimed to quantify ARV utilization and costs in European countries between 2006 and 2015. We also assessed the impact of generic ARV drug utilization on cost reduction in real-life. METHODS ARV drug utilization in 14 European countries (France, Italy, Germany, Denmark, Netherlands, Norway, Sweden, Finland, Iceland, Croatia, Czech Republic, Estonia, Latvia, and Lithuania) were analysed using defined daily dose (DDD)/1000 inhabitants/year. ARV drug cost was estimated in million euro/year and euro/1000 inhabitants/year. The impact of generics on cost reduction was assessed in three countries: France, Denmark, and Czech Republic, using four parameters: expected savings, observed savings, brand price-reduction savings and overall savings. RESULTS Between 2006 and 2015, median ARV drug utilization increased from 234 DDDs per 1000 inhabitants per year (IQR 124-388) to 385 (229-670). The median cost increased from €3751/1000 inhabitants/year (1109-4681) to €9158 (3269-10,646). Between 2013 and 2015, overall savings of €0.9, €1.6, and €33.7 million were respectively observed in Denmark, Czech Republic, and France. CONCLUSION Overall savings observed in real-life from generic ARV drugs in Denmark were related to high rate of low-price generic utilization, contrarily to France and Czech Republic where these were more related to brand price-reduction than generic utilization itself.

Abstract
Minimal information is available regarding antiretroviral prescribing patterns and outcomes for HIV patients in correctional systems. This study analyzes single- (STR) and multiple- (MTR) tablet regimen effectiveness in patients receiving HIV telemedicine care through the Illinois Department of Corrections (IDOC). This study involves a retrospective review of HIV-positive adult patients in IDOC on either an STR (efavirenz, rilpivirine, elvitegravir based) or an MTR (emtricitabine/tenofovir with atazanavir/ritonavir, darunavir/ritonavir, or raltegravir). No significant differences in virologic suppression were seen between groups at baseline, weeks 24, 48, 96, and last clinic visit. Similar proportions of patient-reported adverse effects, self-reported adherence, and discontinuation rates were found in both groups. With similar rates of viral suppression, tolerability, adherence, and discontinuation, administering MTR in the incarcerated population is a viable alternative to STR.

Abstract
OBJECTIVES Treatment guidelines recommend single-tablet regimens for patients with HIV infection starting antiretroviral therapy. These regimens might be as effective and cost less if taken as separate drugs. We assessed whether the one pill once a day combination of efavirenz, emtricitabine and tenofovir reduces the risk of disease progression compared with multiple-pill formulations of the same regimen. METHODS We selected treatment-naïve patients starting one-, two- or three-pill formulations of this regimen in data from the Antiretroviral Therapy Cohort Collaboration. These patients were followed until an AIDS event or death or until they modified their regimen. We analysed these data using Cox regression models, then used our models to predict the potential consequences of exposing a future population to either a one-pill regimen or a three-pill regimen. RESULTS Among 11 739 treatment-naïve patients starting the regimen, there were 386 AIDS events and 87 deaths. Follow-up often ended when patients switched to the same regimen with fewer pills. After the first month, two pills rather than one was associated with an increase in the risk of AIDS or death [hazard ratio (HR) 1.39; 95% confidence interval (CI) 1.01-1.91], but three pills rather than two did not appreciably add to that increase (HR 1.19; 95% CI 0.84-1.68). We estimate that 77 patients would need to be exposed to a one-pill regimen rather than a three-pill regimen for 1 year to avoid one additional AIDS event or death. CONCLUSIONS This particular single-tablet regimen is associated with a modest decrease in the risk of AIDS or death relative to multiple-pill formulations.

Abstract
OBJECTIVE This study aimed to estimate the rate of generic users among HIV-infected patients treated by antiretroviral (ARV) drugs potentially substitutable and to determine factors associated with switch from brand to generic ARV in real-life settings in a French region. METHODS Cohort of HIV-infected patients aged of ≥18 years, exposed to at least one of the generic of lamivudine (3TC-150mg/300mg), zidovudine/lamivudine (AZT-200mg/3TC-150mg), nevirapine (NVP-200mg), efavirenz (EFV-600mg) and those exposed to brand 3TC, AZT/3TC, NVP, EFV, the fixed-dose combination abacavir/lamivudine (ABC/3TC) or the single-tablet regimen efavirenz/emtricitabine/tenofovir (EFV/FTC/TDF) as recorded in the French health insurance database between January 2012 and May 2015 were included. Factors associated with switch (for each generic versus its brand drug; and for situation requiring breaking the combination) were investigated through a logistic regression. RESULTS Among the 1539 patients likely to switch from brand ARV drugs, only 165 (11%) were exposed to generics. For EFV users, switch from brand to generic was associated with age (aOR=1.04 [CI: 1.00-1.08]). For ABC/3TC users, switch was significantly more frequent in patients receiving a monthly average of more than two non-ARV drugs (3.08 [1.42-6.68]) and whose regimen contained a non-nucleoside reverse transcriptase inhibitor (NNRTI) as index medication (3rd agent) (5.68 [2.68-11.39]). By contrast, switch was less frequent in AZT/3TC users exposed to drugs used in digestive disorders (0.39 [0.18-0.88]) or analgesics (0.42 [0.20-0.90]). CONCLUSION Treatment-experienced HIV patients whose disease has been stabilized (less comorbidities) are more likely to switch to generic antiretroviral drugs.

Lung Cancer Mortality Associated With Smoking and Smoking Cessation Among People Living With HIV in the United States. JAMA Intern Med 2017; 177:1613-1621.

Abstract
Importance Lung cancer has become a leading cause of death among people living with human immunodeficiency virus (HIV) (PLWH). Over 40% of PLWH in the United States smoke cigarettes; HIV independently increases the risk of lung cancer. Objective To project cumulative lung cancer mortality by smoking exposure among PLWH in care. Design Using a validated microsimulation model of HIV, we applied standard demographic data and recent HIV/AIDS epidemiology statistics with specific details on smoking exposure, combining smoking status (current, former, or never) and intensity (heavy, moderate, or light). We stratified reported mortality rates attributable to lung cancer and other non-AIDS-related causes by smoking exposure and accounted for an HIV-conferred independent risk of lung cancer. Lung cancer mortality risk ratios (vs never smokers) for male and female current moderate smokers were 23.6 and 24.2, respectively, and for those who quit smoking at age 40 years were 4.3 and 4.5. In sensitivity analyses, we accounted for nonadherence to antiretroviral therapy (ART) and for a range of HIV-conferred risks of death from lung cancer and from other non-AIDS-related diseases (eg, cardiovascular disease). Main Outcomes and Measures Cumulative lung cancer mortality by age 80 years (stratified by sex, age at entry to HIV care, and smoking exposure); total expected lung cancer deaths, accounting for nonadherence to ART. Results Among 40-year-old men with HIV, estimated cumulative lung cancer mortality for heavy, moderate, and light smokers who continued to smoke was 28.9%, 23.0%, and 18.8%, respectively; for those who quit smoking at age 40 years, it was 7.9%, 6.1%, and 4.3%; and for never smokers, it was 1.6%. Among women, the corresponding mortality for current smokers was 27.8%, 20.9%, and 16.6%; for former smokers, it was 7.5%, 5.2%, and 3.7%; and for never smokers, it was 1.2%. ART-adherent individuals who continued to smoke were 6 to 13 times more likely to die from lung cancer than from traditional AIDS-related causes, depending on sex and smoking intensity. Due to greater AIDS-related mortality risks, individuals with incomplete ART adherence had higher overall mortality but lower lung cancer mortality. Applying model projections to the approximately 644 200 PLWH aged 20 to 64 in care in the United States, 59 900 (9.3%) are expected to die from lung cancer if smoking habits do not change. Conclusions and Relevance Those PLWH who adhere to ART but smoke are substantially more likely to die from lung cancer than from AIDS-related causes.

Abstract
BACKGROUND While previous studies have examined HIV cost expenditures within the United States, the majority of these studies focused on data collected prior to or shortly after the advent and uptake of antiretroviral therapy, focused only on a short time frame, or did not provide cost comparisons between HIV/AIDS and other chronic conditions. It is critical that researchers provide accurate and updated information regarding the costs of HIV care to assist key stakeholders with economic planning, policy development, and resource allocation. METHODS We used data from the Medical Expenditure Panel Survey-Household Component for the years 2002-2011, which represents a nationally representative U.S. civilian non-institutionalized population. Using generalized linear modeling, we estimated the adjusted direct medical expenditures by HIV/AIDS status after controlling for confounding factors. RESULTS Data were from 342,732 people living with HIV/AIDS. After adjusting for socio-demographic factors, comorbidities and time trend covariates, the total direct expenditures for HIV/AIDS was $31,147 (95% CI $23,645-$38,648) or 800-900% higher when compared to those without HIV/AIDS (i.e., diabetes, stroke, and cardiovascular disease). Based on the adjusted mean, the aggregate cost of HIV/AIDS was approximately $10.7 billion higher than the costs for those without HIV/AIDS. CONCLUSIONS Our estimates of cost expenditures associated with HIV care over a 10-year period show a financial burden that exceeds previous estimates of direct medical costs. There is a strong need for investment in combination prevention and intervention programs, as they have the potential to reduce HIV transmission, and facilitate longer and healthier living thereby reducing the economic burden of HIV/AIDS.

Abstract
Background The US National HIV/AIDS Strategy (NHAS) aims for 72% (90% diagnosed times 80% of those virally suppressed) viral suppression among persons with human immunodeficiency virus (HIV) by 2020. We examined the clinical and economic impact of reaching this target, in the general US population and among black men who have sex with men (MSM), the group with the highest HIV prevalence. Methods Using a mathematical simulation, we project the 5- and 20-year clinical outcomes, costs, and incremental cost-effectiveness ratios for (1) Current Pace of detection, linkage, retention, and virologic suppression and (2) NHAS investments in expanded testing ($24-$74 per test) and adherence ($400 per person-year), calibrated to achieve 72% suppression by 2020. We examined alternative rates of testing, retention, and suppression and the efficacy and cost of adherence interventions. Results Compared with Current Pace over 20 years, NHAS averted 280000 HIV transmissions (80000 in black MSM) and 199000 (45000) deaths and saved 2138000 (453000) years of life, while increasing costs by 23%. The incremental cost-effectiveness ratio for NHAS compared with Current Pace was $68900 per quality-adjusted life-year ($38300 for black MSM) and was most sensitive to antiretroviral therapy costs. Conclusions Reaching NHAS targets would yield substantial clinical benefits and be cost-effective in both the general US and black MSM populations.

Abstract
BACKGROUND To evaluate the cost-effectiveness of an integrase inhibitor (INI), dolutegravir (DTG), in combination with abacavir (ABC)/lamivudine (3TC) in France, in treatment-naive (TN) HIV adult patients. METHODS The ARAMIS microsimulation Markov model, evaluates costs and effects of DTG vs. first-line ARVs options including INIs (raltegravir, elvitegravir/c), protease inhibitors (PIs) (darunavir/r, atazanavir/r, lopinavir/r), non-nucleoside reverse transcriptase inhibitors (efavirenz and rilpivirine). Efficacy and safety data were derived from phase III studies and network meta-analysis. Treatment algorithms were based on French guidelines and experts opinion. Costs included routine HIV and opportunistic infection care, and death. RESULTS The model showed the fixed-dose combination DTG/ABC/3TC was more effective than all other recommended regimens: patients stayed longer on first-line, and lived longer and healthier. With the exception of EFV, DTG/ABC/3TC was more efficacious and less costly compared to all strategies. The cost per QALY gained (ICER) for DTG compared to EFV was €6,939. DTG/ABC/3TC was more efficacious and less costly compared to INIs and PIs in all deterministic sensitivity analyses. CONCLUSION DTG/ABC/3TC was cost-effective in the management of HIV TN patients in France. These results are mainly explained by its lower price compared to other INIs and PIs, DTG's superior efficacy and high barrier to resistance.

Al-Tabakha MM, Fahelelbom KMS, Obaid DEE, Sayed S. Quality Attributes and In Vitro Bioequivalence of Different Brands of Amoxicillin Trihydrate Tablets. Pharmaceutics 2017; 9:E18. [PMID: 28531119 PMCID: PMC5489935 DOI: 10.3390/pharmaceutics9020018] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2017] [Revised: 05/03/2017] [Accepted: 05/16/2017] [Indexed: 02/04/2023] Open
Abstract
Bacterial resistance and antibiotic drug effectiveness can be related to administering generic products with a subtherapeutic dose or poor in vivo drug release. The aim of this study was to investigate whether locally marketed amoxicillin tablets have the required chemical and physical attributes, including in vitro bioequivalence performance. Five generic products (T1, T2, T3, T4, and T5) containing combination of amoxicillin trihydrate and potassium clavulanate as 1 g strength present in immediate release tablets were compared to the reference listed drug product Augmentin® (R) for weight variation, friability, resistance to crushing, and chemical content of amoxicillin. Difference (ƒ1) and similarity (ƒ2) factors were calculated to assess in vitro bioequivalence requirements. The tablets from different products have shown compliance with the pharmacopeial requirements of the performed tests. The measured resistance to crushing of tablets did not influence the dissolution time. Three generic products released more than 85% of amoxicillin by the first 15 min as did the reference product and were considered as bioequivalent products. T1 and T4 had ƒ1 values of 16.5% and 25.4% respectively and their ƒ2 values were 44.5 and 34.6 respectively, indicating failure to meet in vitro bioequivalence requirements. Tablet formulations can play an important role in achieving bioequivalence. Independent investigations such as this study serve as an important tool to reveal possible inferior or noncompliant products that may find their way to the market.
