Safety and Efficacy of Dolutegravir Plus Rilpivirine in Treatment-Experienced HIV-Infected Patients: The DORIVIR Study.

ABSTRACT: OBJECTIVES:To analyze the efficacy and safety of dolutegravir/rilpivirine (DTG/RPV) in HIV-infected patients who switched from any other antiretroviral therapy (ART). METHODS:Open-label, multicenter study including patients who switched to DTG/RPV between February 2015 and February 2016. Efficacy (HIV RNA <50 copies/mL), adverse events, and metabolic changes at 24 weeks were analyzed. RESULTS:A total of 104 participants were included, who switched for the following reasons: toxicity/intolerance (42.3%), convenience (27.8%), and drug interactions (17.3%). Prior regimens are protease inhibitor (56.7%), integrase strand transfer inhibitor (26.9%), and non-nucleoside reverse transcriptase inhibitor (16.3%). Efficacy at 24 weeks was 88.4% (intention to treat) and 96.8% (per protocol). Triglyceride levels were reduced, on average, by 12.7% and a mean decrease of 9.0% in the glomerular filtration rate was observed as well ( P values of .003 and .002, respectively), whereas total cholesterol, HDL cholesterol, LDL cholesterol, creatinine, and glutamic-pyruvic transaminase remained unchanged. No patient discontinued due to adverse events. CONCLUSIONS:Dolutegravir/RPV is effective and safe in long-term HIV-infected patients under any prior ART. Toxicity, convenience, and interactions were the main reasons for changing. At 24 weeks, the lipid profile improved with a decrease in triglycerides.

Project description:BACKGROUND:The anti-retroviral combination of abacavir/lamivudine plus rilpivirine (ABC/3TC/RPV) is not recommended by international guidelines as the first-line regimen. However, it is potent, well-tolerated, and affordable, especially in resource-limited settings. This study evaluates the efficacy and safety of ABC/3TC/RPV as an initial regimen for treatment-naïve HIV-1 infected patients. METHODS:A retrospective study was conducted in the largest HIV care centre in Singapore, with data collected June 2011 to September 2017. All treatment-naïve HIV-1 infected adults prescribed ABC/3TC as part of their initial anti-retroviral therapy regimen were included. The third drug was a non-nucleoside reverse-transcriptase inhibitor (NNRTI) such as RPV or efavirenz (EFV), or boosted protease-inhibitor (PI). Patients were followed up for 48 weeks. The primary end-point was the percentage of patients achieving virologic suppression, analysed using on-treatment analysis. Secondary outcomes included CD4-count change, treatment discontinuation and treatment-related adverse events. RESULTS:170 patients were included in the study, 66 patients in the RPV group, 104 patients in the comparator group (EFV or boosted PI). 96% (n?=?24) in the RPV group and 87% (n?=?26) in the comparator group achieved viral suppression at 48 weeks (p?=?0.28). Median (interquartile range) time to viral suppression was similar: 17 (14-24) weeks in the RPV group, and 21 (13-26) weeks in the comparator group. There were no statistically significant differences in the CD4 count between the two groups. 14% (n?=?9) of patients on RPV discontinued treatment before 48 weeks, compared to 30% (n?=?31) from the comparator group (p?=?0.053). Of these, 23 discontinuations were due to drug adverse effects, and only 1 attributed to RPV (p?<?0.01). One patient in each group had virologic failure. CONCLUSION:RPV is effective, safe and considerably more tolerable than compared to NNRTI or boosted PI in ABC/3TC-containing regimens for treatment-naïve patients. It offers an affordable and attractive option, especially in resource-limited settings.

Project description:IntroductionLittle information is available on the efficacy and safety of the dual combination of ripivirine plus dolutegravir. This work aims at beginning to fill this gap.MethodsAll HIV-1 infected subjects treated with ripivirine plus dolutegravir between October 2014 and September 2015 in eight Italian centres were included in an observational cohort. Data were collected at baseline and at weeks 4, 12, 24 and 48.ResultsOne hundred and thirty-two subjects were followed for a median of 24 months, mean 33 months. One subject discontinued the study drug at week 24 for headache, one for drug interaction and one died after week 24 of illicit drug abuse. The mean age was 51.8, females 31.7% and non-caucasians 10%. Fifty-seven (43.2%) had at least one failure in their treatment history. Reasons for switching were simplification (53.0%), toxicity (34.8%), drug interactions (n = 7), persistent low-level viremia (n = 4), non-adherence (n = 3) and viral failure (n = 2). Sixty patients (45.5%) had reverse transcriptase (RT) mutations and 69 (44,7%) had protease (PR) mutations. Sixteen had baseline viral replication, 27 had < 50 HIV-1 RNA copies/mL and in 89 (67.4%) no virus was detected (NVD, 0 copies/mL). At w4, 114 (86.4%) had NVD, 15 had 1 to 49 HIV-1 RNA copies/mL and 3 had 50 to 57 copies/mL. At week 24 one subject had viral rebound without mutations due to missed drug refill, 19 had 1 to 49 copies/mL, and 112 had NVD. All 132 subjects were tested at weeks 4 and 24. Of the 50 subjects who had a 48-week follow-up, one had a treatment interruption, four had 1 to 49 copies/mL and 45 had NVD. Among the entire population, one subject had low-level, one intermediate and 4 high-level resistance to rilpivirine: none failed by week 48. Mean serum creatinine increased by +0.1 mg/dL. During the follow-up one patient reported headache and insomnia.ConclusionsRipivirine plus dolutegravir proved safe and effective in this cohort of non-naïve HIV-1 infected subjects.

Project description:A regimen with rilpivirine (RPV), abacavir (ABC) and lamivudine (3TC) is simple and may allow the sparing of tenofovir and protease inhibitors. However, data on use of this combination as a strategy of switch are limited. Aims of the study were to assess the long-term efficacy and safety of this regimen.Retrospective study on HIV-1 infected patients followed at the Infectious Disease Department of the San Raffaele Scientific Institute, HBsAg-negative, HLA B5701-negative, with no documented resistance to RPV, ABC and 3TC, with HIV-RNA<50 copies/mL who started RPV plus ABC/3TC from March 2013 to September 2015. The primary outcome was durability [no treatment failure (TF)]. Secondary objectives were to evaluate changes in immunological, metabolic and other safety parameters. TF was defined as the occurrence of virological failure (VF, 2 consecutive values >50 copies/mL) or discontinuation of any drug in the regimen for any reason. Patients' follow-up accrued from the date of RPV plus ABC/3TC initiation to the date of TF (VF or discontinuation of any drug in the regimen) or to the date of last available visit. Time to TF was evaluated by use of the Kaplan-Meier curves. Mixed linear models were applied to evaluate changes in immunological, metabolic and other safety parameters.In this analysis, 100 patients starting RPV plus ABC/3TC were included. By 12, 24 and 36 months after switching to RPV plus ABC/3TC, the proportions of individuals without TF were 88% [95% confidence interval (CI): 79%-93%], 82% (95% CI:73%-89%) and 78% (95% CI:68%-86%), respectively. Time to TF was not significantly influenced by CD4+ nadir (?200 vs >200 cells/?l; log-rank test: p = 0.311) or pre-ART viral load (<100000 vs ?100000 copies/mL; log-rank test: p = 0.574) or the type of previous antiretroviral regimen (PI+2NRTIs vs NNRTI+2NRTIs vs Other; log-rank test: p = 0.942). Over a median follow-up of 2.9 years (IQR: 1.9-3.5), 26 subjects discontinued the treatment [10 due to toxicity, 7 for interactions with other drugs, 3 due to cardiovascular risk concern, 2 due to single viral blip, 1 due to VF, 1 for asthma, 1 patient's decision, 1 due to enrolment in a study protocol].In this retrospective study, long-term use of RPV plus ABC/3TC regimen is effective and safe. Efficacy of this regimen was not found to be affected by low CD4+ nadir or high pre-ART viral load.
