Abstract
Ainuovirine (ANV), a novel non-nucleoside reverse-transcriptase inhibitor (NNRTI), was approved in China in 2021. In a previous randomized phase 3 trial, ANV demonstrated non-inferior efficacy relative to efavirenz (EFV) and was associated with lower rates of dyslipidemia. In this study, we aimed to explore lipid changes in treatment-experienced people with human immunodeficiency virus (HIV)-1 (PWH) switching to ANV from EFV in real world. At week 24, 96.65% of patients in the ANV group and 93.25% in the EFV group had HIV-1 RNA levels below the limit of quantification (LOQ). Median changes from baseline in CD4 +T cell counts (37.0 vs 36.0 cells/µL, P = 0.886) and CD4+/CD8 +ratio (0.03 vs 0.10, P = 0.360) were similar between the two groups. The ANV group was superior to the EFV group in mean changes in total cholesterol (TC, -0.06 vs 0.26 mmol/L, P = 0.006), triglyceride (TG, -0.6 vs 0.14 mmol/L, P < 0.001), high-density lipoprotein cholesterol (HDL-C, 0.09 vs 0.08 mmol/L, P = 0.006), and low-density lipoprotein cholesterol (LDL-C, -0.18 vs 0.29 mmol/L, P < 0.001) at week 24. We also observed that a higher proportion of patients demonstrated improved TC (13.55% vs 4.45%, P = 0.015) or LDL-C (12.93% vs 6.89%, P = 0.017), and a lower proportion of patients showed worsened LDL-C (5.57% vs 13.52%, P = 0.017) with ANV than with EFV at week 24. In conclusion, we observed good efficacy and favorable changes in lipids in switching to ANV from EFV in treatment-experienced PWH in real world, indicating a promising switching option for PWH who may be more prone to metabolic or cardiovascular diseases.

Abstract
BACKGROUND The evaluation of bictegravir, emtricitabine, and tenofovir alafenamide (BIC/FTC/TAF) in clinical trials has shown high rates of virological suppression but information about its use in real-life settings is scarce. OBJECTIVE To evaluate the effectiveness, safety, durability, and predictive variables of therapeutic failure of BIC/FTC/TAF in a real-life cohort. METHODS This observational, retrospective, multicentered cohort study included treatment-naive (TN) and treatment-experienced (TE) adult patients living with HIV (PLWH) who started treatment with BIC/FTC/TAF from January 1, 2019, to January 31, 2022. Treatment effectiveness (based on intention-to-treat [ITT], modified ITT [mITT], and on-treatment [OT]), tolerability, and safety were evaluated in all patients who started BIC/FTC/TAF antiretroviral therapy. RESULTS We included a total of 505 PLWH of whom 79 (16.6%) were TN and 426 (83.4%) were TE. Patients were followed up for a median (interquartile range [IQR]) of 19.6 (9.6-27.3) months, and 76% and 56% of PLWH reached month 6 and month 12 of treatment, respectively. Rates of TN PLWH with HIV-RNA <50 copies/mL in the OT, mITT, and ITT groups were 94%, 80%, and 62%, respectively, after 12 months of BIC/FTC/TAF treatment. Rates of TE PLWH with HIV-RNA <50 copies/mL were 91%, 88%, and 75% at month 12. The multivariate analysis revealed that neither age, sex, CD4 cell count <200 cells/μL, or viral load >100 000 copies/mL were associated with therapeutic failure. CONCLUSION AND RELEVANCE Our real-life data showed that BIC/FTC/TAF is effective and safe for use in the treatment of both TN and TE patients in clinical practice.

Abstract
OBJECTIVE Limited pharmacokinetic/pharmacodynamic data are a barrier to the scale-up of dolutegravir-based antiretroviral therapy (ART) in children. We examined the pharmacokinetics/pharmacodynamics of the adult film-coated dolutegravir 50 mg tablets in children with HIV infection weighing at least 20 kg. DESIGN A prospective, observational, pharmacokinetic, and safety study. METHODS Treatment-experienced children with HIV weighing at least 20 kg and evidence of viral load suppression on ART were enrolled and switched to dolutegravir-based therapy. After at least 4 weeks and 7 months on dolutegravir-based therapy, blood samples were collected at 0, 1, 4, 8, 12, and 24-h postdose. Dolutegravir concentrations were measured using validated LCMS/MS and pharmacokinetic parameters calculated by noncompartmental analysis. Descriptive statistics were used to summarize pharmacokinetic parameters and comparisons with published reference values. RESULTS Of 25 participants, 92% were on efavirenz-based ART and 60.0% were men. Dolutegravir mean exposure, peak and trough concentrations at both pharmacokinetic visits were higher than the mean reference values in adults and children weighing 20 kg to less than 40 kg treated with 50 mg once daily, but were closer to the mean values in adults given 50 mg twice a day. Children weighing 20 kg to less than 40 kg had even higher dolutegravir exposures. The regimens were well tolerated with good virologic efficacy through week 48. CONCLUSION The higher dolutegravir exposure in our study population suggests that further studies and close monitoring should investigate the adverse effects of dolutegravir in more children and in the long term.

Abstract
BACKGROUND In TANGO, switching to dolutegravir/lamivudine (DTG/3TC) demonstrated long-term noninferior efficacy vs continuing tenofovir alafenamide-based regimens in treatment-experienced adults with HIV-1. The phase 3 SALSA study evaluated efficacy and safety of switching to DTG/3TC compared with continuing various 3-/4-drug current antiretroviral regimens (CARs). METHODS Adults with HIV-1 RNA <50 copies/mL and no previous virologic failure were randomized (1:1, stratified by baseline third agent class) to switch to once-daily fixed-dose combination DTG/3TC or continue CAR (primary endpoint: proportion of participants with HIV-1 RNA ≥50 copies/mL at week 48; Snapshot, intention-to-treat-exposed population, 5% noninferiority margin). RESULTS Overall, 493 adults (39% women; 39% aged ≥50 years; 19% African American/African heritage; 14% Asian) were randomized to switch to DTG/3TC (n = 246) or continue CAR (n = 247). At week 48, 1 (0.4%) participant in the DTG/3TC group and 3 (1.2%) in the CAR group had HIV-1 RNA ≥50 copies/mL (Snapshot), demonstrating noninferiority (adjusted difference, -0.8%; 95% CI, -2.4%, .8%). Zero participants met confirmed virologic withdrawal criteria; therefore, no resistance testing was performed. Drug-related adverse events were more frequent with DTG/3TC (20%) than CAR (6%) through week 48 but comparable post-week 24 (5% vs 2%, respectively). Proximal tubular renal function and bone turnover biomarkers improved with DTG/3TC. Both groups had generally minimal changes in lipids and inflammatory biomarkers. CONCLUSIONS Switching to DTG/3TC was noninferior to continuing CAR for maintaining virologic suppression at week 48 with no observed resistance, supporting the efficacy, good safety, and high barrier to resistance of DTG/3TC.

Abstract
INTRODUCTION Few clinical trials and cohort studies have evaluated the efficacy of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) in people with HIV (PWH) with preexisting M184V/I or other nucleos(t)ide reverse transcriptase inhibitor (NRTI) resistance-associated mutations (RAMs). Real-world data are also scarce. METHODS Retrospective review of treatment-experienced patients who started B/F/TAF in a cohort of PWH. HIV-RNA less than 50 copies/ml was analyzed at 48 weeks in an intention-to-treat (ITT) analysis (missing=failure) and per protocol analysis (patients with missing data or changes for reasons other than virological failure were excluded). Results were compared in patients with and without previous NRTI-RAMs. RESULTS Five hundred and six PWH were included (16.2% women). Median age and time with HIV infection were 52.3 and 18.9 years, respectively. At baseline, viral load was less than 50 copies/ml in 440 patients (86.6%). Overall, 69 (13.6%) participants had documented preexisting NRTI-RAMs: 57 (11.2%) M184V/I and 30 (5.9%) tenofovir RAMs. In the ITT analysis, 83% (420/506) had HIV-RNA less than 50 copies/ml [82.2% (359/437) and 88.4% (61/69) in persons without and with NRTI-RAMs, respectively ( P = 0.2)]. In the per protocol analysis 94.2% (420/445) had HIV-RNA less than 50 copies/ml [94.4% (359/380) vs. 93.8% (61/65); P = 0.2]. A total of 61 participants were excluded from the per protocol analysis (23 missing data, 19 discontinued B/F/TAF because of toxicity, 13 for other reasons, and 6 died). CONCLUSION Switching to B/F/TAF is well tolerated and effective in the real-world setting, even in patients with preexisting NRTI RAMs, such as M184V and RAMs conferring resistance to tenofovir. These results confirm the robustness of this combination.

Abstract
BACKGROUND Switching to dolutegravir/lamivudine (DTG/3TC) was noninferior to continuing tenofovir alafenamide (TAF)-based regimens for maintaining virologic suppression at week 48 of the TANGO study. Here we present week 144 outcomes (efficacy, safety, weight, and biomarkers). METHODS TANGO is a randomized (1:1, stratified by baseline third agent class), open-label, noninferiority phase 3 study. Virologically suppressed (>6 months) adults with human immunodeficiency virus type 1 (HIV-1) switched to once-daily DTG/3TC or continued TAF-based regimens. RESULTS A total of 741 participants received study treatment (DTG/3TC, n = 369; TAF-based regimen, n = 372). At week 144, the proportion of participants with an HIV-1 RNA level ≥50 copies/mL (primary end point, Snapshot; intention-to-treat-exposed population) after switching to DTG/3TC was 0.3% (1 of 369) versus 1.3% (5 of 372) for those continuing TAF-based regimens, demonstrating noninferiority (adjusted treatment difference, -1.1 [95% confidence interval, -2.4 to .2), with DTG/3TC favored in the per-protocol analysis (adjusted treatment difference, -1.1 [-2.3 to -.0]; P = .04). Few participants met confirmed virologic withdrawal criteria (none in the DTG/3TC and 3 in the TAF-based regimen group), with no resistance observed. Drug-related adverse events were more frequent with DTG/3TC (15%; leading to discontinuation in 4%) than TAF-based regimens (5%; leading to discontinuation in 1%) through week 144, but rates were comparable after week 48 (4%; leading to discontinuation in 1% in both groups). Changes from baseline in lipid values generally favored DTG/3TC; no clinical impact on renal function and comparable changes in inflammatory and bone biomarkers across groups were observed. CONCLUSIONS Switching to DTG/3TC demonstrated noninferior and durable efficacy compared with continuing TAF-based regimens in treatment-experienced adults with HIV-1, with good safety and tolerability, and no resistance through 144 weeks.

Abstract
Background The aim of this study is to find out the proportion of treatment-naïve (Tn) and treatment-experienced (Te) patients experiencing HIV drug resistance (DR) to different classes of antiretrovirals (ARVs) being used for HIV treatment and their in class DR correlation. Methods A cross-sectional study was done on 109 HIV patients enrolled at a private hospital in Thane, India, from 2014 to 2019. All patients were tested for CD4 count, viral load, and resistance to ARVs. Results Sixty-six patients were Tn and 43 patients were Te. Among Tn and Te patients, the percentage of high-level resistance (HLR) for nonnucleoside reverse transcriptase inhibitors (NNRTI) was 4.55% and 37.8%, respectively, for nucleoside reverse transcriptase inhibitors (NRTI) was 0.43% and 36.4%, respectively. No HLR was observed for protease inhibitors (PIs) among Tn patients, while Te patients showed 2.62% HLR. Tn and Te patients showed high susceptibility for Darunavir (98.48% and 95.34%, respectively) followed by Atazanavir and Lopinavir (96.96%, each and 90.69%, each). Tn patients showed HLR for Lamivudine and Emtricitabine (1.52%, each). Integrase Strand Transfer Inhibitors were susceptible (100%) in both Tn and Te patients. A positive correlation was observed for within class across ARVs. Conclusion An increased incidence of HLR was observed for NNRTI as compared to NRTI while PIs and integrase strand transfer inhibitors (INSTIs) demonstrated no HLR in either group of patients. When selecting a regimen for Tn patients consisting of NRTIs + NNRTIs genotypic DR test is essential. While with PIs or INSTIs its optional. Among Te patients, DR testing is recommended for all classes of drugs.

Abstract
OBJECTIVES To explore the effectiveness and durability of integrase strand transfer inhibitor (INSTI)-based regimens in pre-treated subjects. METHODS Treatment-experienced individuals starting an INSTI-based regimen during 2012-2019 were selected from the INTEGRATE collaborative study. The time to virological failure [VF: one measurement of viral load (VL) ≥ 1000 copies/mL or two ≥ 50 copies/ml or one VL measurement ≥ 50 copies/mL followed by treatment change] and to INSTI discontinuation were evaluated. RESULTS Of 13 560 treatments analysed, 4284 were from INSTI-naïve, non-viraemic (IN-NV) individuals, 1465 were from INSTI-naïve, viraemic (IN-V) individuals, 6016 were from INSTI-experienced, non-viraemic (IE-NV) individuals and 1795 were from INSTI-experienced, viraemic (IE-V) individuals. Major INSTI drug resistance mutations (DRMs) were previously detected in 4/519 (0.8%) IN-NV, 3/394 (0.8%) IN-V, 7/1510 (0.5%) IE-NV and 25/935 (2.7%) IE-V individuals. The 1-year estimated probabilities of VF were 3.1% [95% confidence interval (CI): 2.5-3.8] in IN-NV, 18.4% (95% CI: 15.8-21.2) in IN-V, 4.2% (95% CI: 3.6-4.9) in IE-NV and 23.9% (95% CI: 20.9-26.9) in IE-V subjects. The 1-year estimated probabilities of INSTI discontinuation were 12.1% (95% CI: 11.1-13.0) in IN-NV, 19.6% (95% CI: 17.5-21.6) in IN-V, 10.8% (95% CI: 10.0-11.6) in IE-NV and 21.7% (95% CI: 19.7-23.5) in IE-V subjects. CONCLUSIONS Both VF and INSTI discontinuation occur at substantial rates in viraemic subjects. Detection of DRMs in a proportion of INSTI-experienced individuals makes INSTI resistance testing mandatory after failure.

Abstract
HIV drug resistance testing is fundamental in clinical patient management, but data on HIV-1 drug-resistant mutations (DRMs) is scarce in the Caribbean and in Suriname limited to one survey on transmitted resistance. The aim of this study was to address this gap, to gain insight in acquired HIV drug resistance (ADR) prevalence and mutation patterns, and to improve HIV-1 treatment outcome of people living with HIV (PLHIV) in Suriname. A prospective cross-sectional study was conducted from July 2018 through January 2019 among treatment-experienced PLHIV (n = 72), with either treatment failure or antiretroviral therapy restart. Genotypic drug resistance testing was performed and DRM impact on drug effectiveness was examined. Genotypic drug resistance testing revealed 97.2% HIV-1 subtype B, 2.8% B/D recombinants and a ADR prevalence of 63.2% in treatment failure patients, with a predominance of nonnucleoside reverse transcriptase inhibitor (NNRTI) mutations. The most common DRMs were M184V (23.6%) and K103N (18.8%). A high level of non-DRM polymorphisms was observed in both the reverse transcriptase (RT) and protease (PR) gene. Interesting deviations from the existing mutation datasets were noted at position E248 and R83 of the RT gene and L63 and V77 in the PR gene. Full susceptibility to all examined drugs was 54.2%, while high-level drug resistance was estimated at 37.5%, which seems promising for treatment outcomes for PLHIV in Suriname, although cross-resistance to next-generation NNRTIs was already estimated for nearly a quarter of the patients. The meager 2.9% of PR DRMs rendered protease inhibitors as an effective rescue HIV-1 treatment.

Abstract
ABSTRACT Ibalizumab, a humanized monoclonal antibody targeting CD4, blocks HIV-1 entry into cells and is the first Food and Drug Adminstration-approved long-acting agent for HIV-1 treatment. In this phase 2a study, 82 HIV-infected adults failing antiretroviral therapy were assigned an individually optimized background regimen (OBR) and randomized 1:1:1 to arm A (15 mg/kg ibalizumab q2wk), arm B (10 mg/kg weekly for 9 weeks, then q2wk), or placebo. Subjects with an inadequate response at week 16 were permitted to cross over to a new OBR plus 15 mg/kg ibalizumab q2wk. At week 16, viral load (VL) reduction was significantly greater than placebo (0.26 log10) in arms A (1.07 log10; P = 0.002) and B (1.33 log10; P < 0.001); CD4+ T cell counts increased significantly in arm A. After week 16, 11/27 (arm B) and 19/27 (placebo) subjects crossed over to OBR plus 15 mg/kg ibalizumab; 8/28 in arm A initiated a new OBR. Ibalizumab treatment resulted in VL reduction at week 24 (-0.77 and -1.19 log10 for arms A and B, respectively, versus -0.32 log10 for placebo) and 48 weeks (-0.54 and -0.77 versus -0.22 log10). Compared with placebo, VL differences were statistically significant for arm B at week 24 (P = 0.001) and week 48 (P = 0.027). CD4+ T cell counts increased significantly by week 48 in both arm A and arm B, relative to placebo. No ibalizumab-related serious adverse events were reported. The durable antiviral activity and tolerability of ibalizumab support its use in treating individuals harboring multidrug-resistant HIV-1.

Abstract
BACKGROUND Women face unique complexities in HIV treatment yet are underrepresented in antiretroviral therapy (ART) studies. OBJECTIVE This analysis assessed the one-year durability of the first integrase strand transfer inhibitor (INSTI)-based regimens prescribed to women in a large cohort of patients living with HIV in care. METHODS Women with HIV who initiated their first INSTI-containing regimen between 08/12/2013 and 11/30/2015 were identified in the OPERA cohort, a collaboration of 79 US outpatient clinics. Discontinuation within the first year of treatment with an INSTI was compared between dolutegravir (DTG), raltegravir (RAL) and elvitegravir (EVG), using multivariable Cox regression and Kaplan- Meier estimates. Virologic response and regimen modifications were described and compared across INSTIs. RESULTS A total of 537 treatment-naïve (DTG: 39%, EVG: 48%, RAL: 13%) and 878 treatmentexperienced (DTG: 57%, EVG: 29%, RAL: 13%) women were analyzed. In the first twelve months after initiation, women taking EVG or RAL were more likely to discontinue their initial INSTI than those taking DTG among both treatment-naïve (adjusted hazard ratio EVG vs. DTG: 1.59 (95% CI: 1.09, 2.39); RAL vs. DTG: 2.46 (1.49, 4.05)) and treatment-experienced women (EVG vs. DTG: 1.39 (1.02, 1.88); RAL vs. DTG: 2.17 (1.51, 3.12)). Following discontinuation of the initial INSTI, women commonly switched to a regimen containing a different drug from the INSTI class (treatment-naïve DTG: 34%, RAL: 33% EVG: 41%; treatment-experienced DTG: 23%, RAL: 19% EVG: 41%). CONCLUSION In treatment-naïve and treatment-experienced women living with HIV, women taking DTG had the lowest risk for early (≤1 year) discontinuation.

Abstract
INTRODUCTION Despite high efficacy of current direct-acting antiviral agents (DAAs) in treating chronic hepatitis C virus (HCV) infection, a small portion of patients fail treatment. QUARTZ-I was a phase 2, open-label, multicenter, two-part study that assessed the safety and efficacy of ombitasvir/paritaprevir/ritonavir (OBV/PTV/r) with dasabuvir (DSV) with or without the addition of sofosbuvir (SOF) and/or ribavirin (RBV) in DAA treatment-experienced adults with chronic HCV GT1 infection. MATERIALS AND METHODS Genotype 1 HCV-infected patients with or without compensated cirrhosis had prior treatment failure to any DAA (part 1) or ledipasvir/SOF (part 2). Patients received OBV/PTV/r + DSV ± SOF with or without RBV for 12 or 24 weeks. The primary endpoint of this study is the percentage of patients achieving sustained virologic response at post-treatment week 12 (SVR12). RESULTS In part 1 of the study, 95.5% (21/22) of patients achieved SVR12, and in part 2, the SVR12 rate was 85.7% (6/7). Most adverse events (AEs) were mild and moderate in severity. Two serious AEs occurred and were assessed as not being related to study drug, of which one resulted in study drug discontinuation. Two patients experienced grade 3 elevations of serum alanine aminotransferase, and no other grade ≥3 laboratory abnormalities were observed. CONCLUSION The multi-targeted regimen of OBV/PTV/r + DSV ± SOF with or without RBV was effective in the treatment of patients who failed previous DAA regimens including NS3/4A protease and NS5A and NS5B polymerase inhibitors. These results provide a promising outcome for patients that traditionally had limited treatment options.

Abstract
BACKGROUND & AIMS We report data from two similarly designed studies that evaluated the efficacy, safety, and optimal duration of ledipasvir/sofosbuvir (LDV/SOF) ± ribavirin (RBV) for retreatment of chronic hepatitis C virus (HCV) in individuals who failed to achieve sustained virological response (SVR) with prior SOF-based, non-NS5A inhibitor-containing regimens. METHODS The RESCUE study enrolled HCV mono-infected adults with genotype (GT) 1 or 4. Non-cirrhotic participants were randomized to 12 weeks of LDV/SOF or LDV/SOF + RBV. Compensated cirrhotic participants were randomized to LDV/SOF + RBV (12 weeks) or LDV/SOF (24 weeks). The AIDS Clinical Trials Group A5348 study randomized genotype 1 adults with HCV/HIV co-infection to LDV/SOF + RBV (12 weeks) or LDV/SOF (24 weeks). Both studies used SVR at 12 weeks post-treatment (SVR12) as the primary endpoint. RESULTS In the RESCUE study, 82 participants were randomized and treated, and all completed treatment. Overall, SVR12 was 88% (72/82); 81-100% in non-cirrhotic participants treated with LDV/SOF or LDV/SOF + RBV for 12 weeks and 80-92% in cirrhotic participants treated with LDV/SOF + RBV for 12 weeks or LDV/SOF for 24 weeks. Adverse events (AEs), mostly mild-to-moderate in severity, were experienced by 78% of participants, with headache and fatigue most frequently reported. One serious AE, not related to treatment, was observed. No premature discontinuations of study drug, or deaths occurred. In the A5348 study, seven participants were randomized (cirrhotic n = 1; GT1a n = 5) and all attained SVR12, with no serious AEs or premature discontinuations. CONCLUSIONS In this SOF-experienced, NS5A inhibitor-naïve population, which included participants with cirrhosis or HCV/HIV co-infection, high SVR12 rates were achieved.

Abstract
BACKGROUND/PURPOSE Pegylated interferon (PegIFN) plus ribavirin (RBV) combination therapy has been the standard of care since 2002. Although a better viral response has been achieved among chronic hepatitis C (CHC) patients in Taiwan, approximately 25% of hepatitis C virus (HCV) genotype 1 (G1) patients and 15% of G2 patients failed to achieve a sustained virological response (SVR) at the first therapy. The actual cost-effectiveness of the retreatment remains elusive. The present study conducted a real-world cost-effectiveness analysis of a large cohort among different pre-specified subgroups of treatment-experienced CHC patients. METHODS A total of 117 patients with CHC who failed to achieve SVR at the first IFN-based therapy and received a second IFN-based therapy were enrolled. The inpatient and outpatient costs were acquired from National Health Insurance Research Database of Taiwan. The related medical care costs per treatment and per SVR were calculated. RESULTS We demonstrated that the average cost per SVR achieved was $13,722 in treatment-experienced CHC patients. Especially, patients with HCV G1 infection, baseline viral loads > 400,000 IU/mL, advanced hepatic fibrosis, not achieving a rapid viral response at week 4 or complete early viral response at week 12, had poorer cost-effectiveness for PegIFN/RBV retherapy, ranging from around $15,520 to as high as $72,546 per SVR achieved. CONCLUSION In the current study, we explored the real-world cost-effectiveness data of PegIFN/RBV for different subgroups of treatment-experienced HCV patients. These findings provide information for policy-makers for making decisions on treatment strategies of costly direct-acting antiviral agents for retreating CHC patients.

Abstract
The aim of this study was to characterize the treatment response and tolerability of sofosbuvir plus ribavirin therapies in Japanese patients infected with hepatitis C virus (HCV) genotype (GT)-2. This retrospective study analyzed 114 Japanese HCV GT-2 patients treated for 12 weeks with 400 mg of sofosbuvir plus weight-based ribavirin daily. This treatment led to higher sustained virologic response at 12-weeks post-treatment (SVR12) rates in both treatment-naïve and treatment-experienced patients. The efficacy of this treatment in compensated cirrhotics was the same as that in patients with chronic hepatitis. HCV GT-2a infection and lower estimated glomerular filtration rates (eGFR) tended to be associated with SVR12. Of 114 patients, 113 completed the combination of sofosbuvir plus ribavirin for 12 weeks. Seven patients without SVR12 did not have HCV NS5B-S282 mutations. The overall SVR12 rate was 90.4% (103 of 114). More effective therapeutic options with less adverse events are desired to achieve higher SVR rates in HCV GT-2 Japanese patients.

Abstract
AIM We evaluated the safety and efficacy of the hepatitis C virus (HCV) NS3/4A A protease inhibitor faldaprevir plus pegylated interferon α-2b and ribavirin (PegIFNα-2b/RBV) in Japanese patients with HCV genotype-1 infection. METHODS Treatment-naïve patients were randomized (1:1) to faldaprevir 120 mg q.d. for 12 or 24 weeks (response-guided therapy [RGT], n = 44), or faldaprevir 240 mg q.d. for 12 weeks (n = 43), each combined with PegIFNα-2b/RBV for 24 or 48 weeks (RGT). Response-guided therapy was based on early treatment success (HCV RNA <25 IU/mL at week 4 and <25 IU/mL undetected at week 8). Treatment-experienced patients received 240 mg q.d. for 24 weeks, plus PegIFNα-2b/RBV RGT (24 or 48 weeks, prior relapsers, n = 29) or PegIFNα-2b/RBV (48 weeks, 5 prior partial responders/breakthroughs, 10 prior null responders). The primary objective was safety; sustained virologic response 12 weeks post-treatment (SVR12) was a secondary end-point. RESULTS All except one patient experienced drug-related adverse events. Adverse events led to faldaprevir discontinuation in 1 (2%), 13 (20%), and 3 (6.8%) patients on faldaprevir 120 mg, faldaprevir 240 mg 12 weeks, and faldaprevir 240 mg 24 weeks, respectively. The SVR12 rates were: 86% with faldaprevir 120 mg and 74% with faldaprevir 240 mg among treatment-naïve patients; and 86%, 60%, and 40% among prior relapsers, partial responders/breakthroughs, and null responders, respectively. CONCLUSIONS In treatment-naïve Japanese patients, faldaprevir 120 mg q.d. plus PegIFNα-2b/RBV was better tolerated than faldaprevir 240 mg q.d. plus PegIFNα-2b/RBV, with at least comparable efficacy. In treatment-experienced patients, most prior relapsers achieved SVR12 with 24 weeks of faldaprevir 240 mg q.d. plus PegIFNα-2b/RBV. Clinicaltrials.gov NCT01579474.

Abstract
Faldaprevir, a hepatitis C virus (HCV) NS3/4A protease inhibitor, was evaluated in HCV genotype 1-infected patients who failed peginterferon and ribavirin (PegIFN/RBV) treatment during one of three prior faldaprevir trials. Patients who received placebo plus PegIFN/RBV and had virological failure during a prior trial were enrolled and treated in two cohorts: prior relapsers (n = 43) and prior nonresponders (null responders, partial responders and patients with breakthrough; n = 75). Both cohorts received faldaprevir 240 mg once daily plus PegIFN/RBV for 24 weeks. Prior relapsers with early treatment success (ETS; HCV RNA <25 IU/mL detectable or undetectable at week 4 and <25 IU/mL undetectable at week 8) stopped treatment at week 24. Others received PegIFN/RBV through week 48. The primary efficacy endpoint was sustained virological response (HCV RNA <25 IU/mL undetectable) 12 weeks post treatment (SVR12). More prior nonresponders than prior relapsers had baseline HCV RNA ≥ 800,000 IU/mL (80% vs 58%) and a non-CC IL28B genotype (91% vs 70%). Rates of SVR12 (95% CI) were 95.3% (89.1, 100.0) among prior relapsers and 54.7% (43.4, 65.9) among prior nonresponders; corresponding ETS rates were 97.7% and 65.3%. Adverse events led to faldaprevir discontinuations in 3% of patients. The most common Division of AIDS Grade ≥ 2 adverse events were anaemia (13%), nausea (10%) and hyperbilirubinaemia (9%). In conclusion, faldaprevir plus PegIFN/RBV achieved clinically meaningful SVR12 rates in patients who failed PegIFN/RBV in a prior trial, with response rates higher among prior relapsers than among prior nonresponders. The adverse event profile was consistent with the known safety profile of faldaprevir.

Abstract
BACKGROUND The use of pegylated interferon alpha and ribavirin (PegIFN/RBV) for the retreatment of chronic hepatitis C virus (HCV) infection without a sustained virological response (SVR) prior to PegIFN/RBV treatment has resulted in low success rates. AIMS To investigate the efficacy and safety of telaprevir (TVR) in combination with PegIFN/RBV in patients infected with HCV genotypes 1 and 4 who were previously treated with PegIFN/RBV and failed to achieve SVR. STUDY DESIGN Multi-center, retrospective, cross-sectional study. METHODS The study included 111 patients: 80 prior relapsers, 25 prior null responders, and six prior partial responders to PegIFN/RBV treatment. The patients were given TVR/PegIFN/RBV for 12 weeks, followed by a 12-week PegIFN/RBV treatment; virological response results were assessed at weeks 4, 12, and 24. Treatment was discontinued in patients with HCV RNA >1000 IU/mL at week 4 or with negative RNA results at week 4 but >1000 IU/mL at week 12. Rapid virological response (RVR), early virological response (EVR), extended rapid virological response (eRVR), and virological response at 24th week of treatment were evaluated. The side effects of combination therapy and the rates of treatment discontinuation were investigated. RESULTS The mean age of the patients was 56.02±9.96 years and 45.9% were male. Ninety-one percent of the patients were infected with viral genotype 1, 69.6% with the interleukin (IL) 28B genotype CT and 20.2% were cirrhotic. The RVR rate was 86.3% in prior relapsers, 56% in prior null responders, and 50% in prior partial responders (p=0.002). EVR rates in those groups were 91.3%, 56%, and 83.3%, respectively (p<0.001). eRVR rates were 83.8% in prior relapsers, 48% in prior null responders, and 50% in prior partial responders (<0.001). The virological response at the 24th week of treatment was found to be the highest in prior relapsers (88.8%); it was 56% in prior null responders and 66.7% in prior partial responders (p<0.001). Common side effects were fatigue, headache, anorexia, malaise, anemia, pruritus, dry skin, rash, dyspepsia, nausea, pyrexia, stomachache, and anorectal discomfort. All treatments were discontinued due to side effects in 9.9% of patients. CONCLUSION High virological response rates were obtained with TVR/PegIFN/RBV treatment. Although side effects were frequently observed, the discontinuation rate of combination therapy was low.

Abstract
OBJECTIVES Following antiretroviral therapy failure, patients are often treated with a three-drug regimen that includes two nucleoside/tide reverse transcriptase inhibitors [N(t)RTIs]. An alternative two-drug nucleoside-sparing regimen may decrease the pill burden and drug toxicities associated with the use of N(t)RTIs. The Intelence aNd pRezista Once A Day Study (INROADS; NCT01199939) evaluated the nucleoside-sparing regimen of etravirine 400 mg with darunavir/ritonavir 800/100 mg once-daily in HIV-1-infected treatment-experienced subjects or treatment-naïve subjects with transmitted resistance. METHODS In this exploratory phase 2b, single-arm, open-label, multicentre, 48-week study, the primary endpoint was the proportion of subjects who achieved HIV-1 RNA < 50 copies/mL at week 48 [confirmed virological response (CVR), non-virological failure (VF) censored]. Key secondary endpoints included assessments of changes from baseline to week 48 in viral load, immunological response, pharmacokinetics/pharmacodynamics, safety, tolerability, metabolic and bone markers and body fat. RESULTS Forty-one of the 54 enrolled subjects completed the study. Adverse events (7%) and VF (7%) were the most common reasons for discontinuation. The week 48 CVR rate in the intent-to-treat (ITT) non-VF censored population was 89% (primary endpoint). Seven subjects experienced VF. Common adverse events were diarrhoea (15%), rash (15%) and upper respiratory tract infection (11%). Mild/moderate lipid elevations, minimal changes in limb fat distribution and bone mineral density and no clinically relevant changes in glucose metabolism were observed. CONCLUSIONS Etravirine 400 mg and darunavir/ritonavir 800/100 mg as a two-drug once-daily regimen in treatment-experienced subjects or treatment-naïve subjects with transmitted resistance was virologically efficacious and well tolerated.
