Abstract
Aim of this study was to assess the predictors of virological failure (VF) among patients living with HIV (PLWHIV) switching from an effective first-line antiretroviral therapy (ART) regimen, and to evaluate the emergence of resistance-associated mutations. All adult patients enrolled in the Antiviral Response Cohort Analysis cohort who started ART after 2010, with at least 6 months of virological suppression (VS) before ART switch and with an available genotypic resistance test (GRT) at baseline were included. Thirty-two patients out of the 607 PLWHIV included (5.3%) experienced VF after a median of 11 months from ART switch. Younger age (adjusted Hazard Ratio [aHR] 0.96, 95% confidence interval [CI] 0.92-0.99, p = .023), being male who have sex with male (aHR 0.15, 95% CI 0.03-0.69, p = .014), and longer time from VS to ART switch (aHR 0.97, 95% CI 0.95-1.00, p = .021) resulted protective toward VF, while receiving a first-line regimen containing a backbone other than ABC/3TC or TXF/FTC (aHR 3.61, 95% CI 1.00-13.1, p = .050) and a boosted protease inhibitor as anchor drug (aHR 3.34, 95% CI 1.20-9.28, p = .021) were associated with higher risk of VF. GRT at the moment of VF was available only for 13 patients (40.6%). ART switch in patients with stable control of HIV infection is a safe practice, even if particular attention should be paid in certain cases of patients switching from regimens containing low-performance backbones or protease inhibitors.

Efficacy and improvement of lipid profile after switching to rilpivirine in resource limited setting: real life clinical practice. AIDS Res Ther 2019; 16:7.

Abstract
Background Long-term success of cART is possible if the regimen is convenient and less-toxic. This study assessed the efficacy and safety of switching from a first-line NNRTI or boosted PI-based regimens to RPV-based regimens among virologically suppressed participants in resource-limited setting (RLS). Methods This is a prospective cohort study. Participants with plasma HIV-RNA < 50 copies/mL receiving cART were switched from a PI- or NNRTI-based, to a RPV-based regimen between January 2011 and April 2018. The primary endpoint was the proportion of patients with plasma HIV-1 RNA level < 50 copies/mL after 12 months of RPV. The secondary endpoint was the virological response at 24 months and safety endpoint (change in lipid profiles and kidney function from baseline to 12 months). Results A total of 320 participants were enrolled into the study. The rationale for switching to RPV was based on toxicity of the current regimen (57%) or desire to simplify cART (41%). Totally, 177 (55%) and 143 (45%) participants were on NNRTI and boosted PI, respectively, prior to switching to RPV. After 12 months, 298 (93%) participants maintained virological suppression. There were significant improvements in the lipid parameters: TC (− 21 (IQR − 47 to 1) mg/dL; p < 0.001), LDL (− 14 (IQR − 37 to 11) mg/dL; p < 0.001) and TG (− 22 (IQR − 74 to 10) mg/dL; p < 0.001). Also, there was a small but statistically significant decrease in eGFR (− 4.3 (IQR − 12 to 1.1) mL/min per 1.73m2; p < 0.001). Conclusions In RLS where integrase inhibitors are not affordable, RPV-based regimens are a good alternative option for PLHIV who cannot tolerate first-line NNRTI or boosted PI regimen, without prior NNRTI/PI resistance. Trial registration HIV-NAT 006 cohort, clinical trial number: NCT00411983

Abstract
Simplifying or switching antiretroviral therapy (ART) in treatment-experienced people living with HIV (PLWH) may improve adherence, tolerability, toxicities, and/or drug-drug interactions. The purpose of this review is to critically evaluate the literature for efficacy and safety associated with switching or simplifying ART in treatment-experienced PLWH. A systematic literature search using MEDLINE was performed from January 1, 2010 to April 30, 2018. References within articles of interest, the Department of Health and Human Services guidelines, and conference abstracts were also reviewed. Switch/simplification strategies were categorized as those supported by high-level clinical evidence and those with emerging data. Rates of virologic suppression were noninferior for several switch/simplification strategies when compared to baseline ART. Potential for reducing adverse events was also seen. Additional evidence for some strategies, including most 2-drug regimens, is needed before they can be recommended.

Abstract
Objectives To evaluate the maintenance of virological suppression (VS) in antiretroviral-treated HIV-1-suppressed patients switching to a tenofovir/emtricitabine/rilpivirine (TDF/FTC/RPV) single-tablet regimen, by considering pre-existent resistance (pRes). Methods pRes was evaluated according to resistance on all previous plasma genotypic resistance tests. Probability and predictors of virological rebound (VR) were evaluated. Results Three hundred and nine patients were analysed; 5.8% of them showed resistance to both NRTIs and NNRTIs, while 12.6% showed resistance to only one of these drug classes. By 72 weeks, the probability of VR was 11.3%. A higher probability of VR was found in the following groups: (i) patients with NRTI + NNRTI pRes compared with those harbouring NRTI or NNRTI pRes and with those without reverse transcriptase inhibitor pRes (39.2% versus 11.5% versus 9.4%, P < 0.0001); (ii) patients with a virus with full/intermediate resistance to both tenofovir/emtricitabine and rilpivirine compared with those having a virus with full/intermediate resistance to tenofovir/emtricitabine or rilpivirine and those having a virus fully susceptible to TDF/FTC/RPV (36.4% versus 17.8% versus 9.7%, P < 0.001); and (iii) patients with pre-therapy viraemia >500 000 copies/mL compared with those with lower viraemia levels (>500 000: 16.0%; 100 000-500 000: 9.3%; <100 000 copies/mL: 4.8%, P = 0.009). pRes and pre-therapy viraemia >500 000 copies/mL were independent predictors of VR by multivariable Cox regression. Conclusions TDF/FTC/RPV as a treatment simplification strategy shows a very high rate of VS maintenance. The presence of pRes to both NRTIs and NNRTIs and a pre-therapy viraemia >500 000 copies/mL are associated with an increased risk of VR, highlighting the need for an accurate selection of patients before simplification.

Abstract
OBJECTIVES This study evaluates the effectiveness, safety and costs of switching to a rilpivirine/emtricitabine/tenofovir disoproxil fumarate (RPV/FTC/TDF) regimen in treatment-experienced HIV-1-infected patients with sustained virological suppression. METHODS Observational, prospective study. Study population included all treatment-experienced patients with sustained virological suppression who switched to RPV/FTC/TDF during 2013 in a tertiary hospital. Patients were followed until they completed 96 weeks of treatment. The effectiveness end-point was defined as the proportion of patients who maintained virological suppression at week 96 by intention-to-treat analysis (discontinuation=failure). The safety of RPV/FTC/TDF (incidence of adverse events leading to discontinuation and laboratory abnormalities) and adherence to this regimen were evaluated, and the cost of switching was analysed. RESULTS One-hundred forty-six patients were included. At week 96, 71.9% of patients remained virologically suppressed; 6.8% experienced virological failure. During follow-up, 25.3% of patients discontinued RPV/FTC/TDF (14.4% because of adverse events, mainly renal impairment). Throughout the 96 weeks, there were significant decreases in total cholesterol (TC) (14.0 mg/dL, P<.001), TC/HDL cholesterol ratio (0.4 mg/dL, P=.019) and triglycerides (42.0 mg/dL, P<.001). A slight decrease in glomerular filtration rate was observed (4.3 mL/min/1.73 m2 , P<.001). Switching to RPV/FTC/TDF improved adherence in the subgroup of patients whose previous treatment was based on a twice-daily schedule, although differences did not reach statistical significance. Switching to RPV/FTC/TDF reduced the annual per-patient antiretroviral cost by €1744 (P<.001). CONCLUSIONS In virologically suppressed patients, the switch to a RPV/FTC/TDF regimen was associated with a mild but maintained improvement in lipid parameters and a significant reduction in costs. However, the relatively high rates of virological failure and treatment discontinuation because of adverse events make this combination a less favourable choice over other regimens currently available.

Abstract
BACKGROUND Tenofovir DF/FTC/rilpivirine (TDF/FTC/RPV) is a single tablet regimen considered as safe and efficacious in HIV population as long as food requirements, concomitant PPI administration, and compromised antiviral activity have been carefully reviewed. We evaluated TDF/FTC/RPV in a real-life setting with focus on clinical and virological outcomes. METHODS OCEAN II is a prospective, two-centre observational study. From September 2012 to December 2013, antiretroviral-naive patients with HIV RNA <100,000 copies/mL or wishing to switch for simplification were considered for TDF/FTC/RPV. A systematic review of potential obstacles to TDF/FTC/RPV administration was undertaken during a multidisciplinary meeting, including DNA genotyping to detect archived RPV and/or NRTI-associated resistance mutations if historical RNA resistance testing was lacking. RESULTS TDF/FTC/RPV was considered for 480 patients, however was not offered to 194 patients (40%), mainly because of risk of insufficient virological efficacy, issues on adherence, patient refusal, meal constraint, or PPI therapy. A total of 286 patients (269 in maintenance; 17 ART-naive) received TDF/FTC/RPV. After a median follow-up of 30 months, virological failure occurred in five patients (1.7%) without the emergence of resistance mutations. Discontinuation of TDF/FTC/RPV occurred in 98 patients, due to adverse events in 43 patients (44%) and non-safety reasons in 55 patients (56%). No grade three-fourth adverse events occurred. CONCLUSION In this real-life experience, cohort consisting primarily of virologically suppressed patients, TDF/FTC/RPV usually maintained virologic suppression. Discontinuation of therapy because of intolerability was due to mild adverse events. Strict clinical and virological screening probably explained the low rate of virological failure.

Abstract
Supplemental Digital Content is Available in the Text. Background: Study aim was to estimate the rate and identify predictors of discontinuation of first combination antiretroviral therapy (cART) in recent years. Methods: Patients who initiated first cART between January 2008 and October 2014 were included. Discontinuation was defined as stop of at least 1 drug of the regimen, regardless of the reason. All causes of discontinuation were evaluated and 3 main endpoints were considered: toxicity, intolerance, and simplification. Predictors of discontinuation were examined separately for all 3 endpoints. Kaplan–Meier analysis was used for the outcome discontinuation of ≥1 drug regardless of the reason. Cox regression analysis was used to identify factors associated with treatment discontinuation because of the 3 reasons considered. Results: A total of 4052 patients were included. Main reason for stopping at least 1 drug were simplification (29%), intolerance (21%), toxicity (19%), other causes (18%), failure (8%), planned discontinuation (4%), and nonadherence (2%). In a multivariable Cox model, predictors of discontinuation for simplification were heterosexual transmission (P = 0.007), being immigrant (P = 0.017), higher nadir lymphocyte T CD4+ cell (P = 0.011), and higher lymphocyte T CD8+ cell count (P = 0.025); for discontinuation due to intolerance: the use of statins (P = 0.029), higher blood glucose levels (P = 0.050). About toxicity: higher blood glucose levels (P = 0.010) and the use of zidovudine/lamivudine as backbone (P = 0.044). Conclusions: In the late cART era, the main reason for stopping the initial regimen is simplification. This scenario reflects the changes in recommendations aimed to enhance adherence and quality of life, and minimize drug toxicity.

Abstract
BACKGROUND Rilpivirine (RPV) is a second-generation once-daily non-nucleoside reverse transcriptase inhibitor (NNRTI) which has shown non-inferior antiviral activity to efavirenz in treatment-naive patients. Data in treatment-experienced patients are more limited. We wished to assess the efficacy and safety of a switch to RPV-based regimens in well-suppressed treatment-experienced patients. METHODS Between September 2012 and June 2013, all antiretroviral therapy (ART)-experienced HIV-1-infected patients with a plasma HIV RNA level <50 copies/ml, and switching to an RPV-based regimen, were analysed in this retrospective observational monocentric cohort study. The primary end point was the proportion of patients with virological success defined as a plasma HIV RNA level <50 copies/ml at 12 months using the FDA snapshot algorithm. RESULTS A total of 281 participants were studied and 97% received a combination of RPV/tenofovir disoproxil fumarate/emtricitabine. At month 12, the rate of virological success was 59% and increased to 72% using available data beyond month 12. Sixteen (6%) patients experienced virological failure, which was associated with the presence of the M184V/I resistance mutation in prior genotypes (P=0.02) and the use of a non-NNRTI as third agent before the switch (P=0.03). RPV-based regimens were overall well tolerated and only 23 (8%) patients discontinued ART because of adverse events, mostly neuropsychiatric adverse events. Switching to RPV was associated with significant but modest improvement of the lipid profile. CONCLUSIONS In patients fully suppressed on ART, a switch to an RPV-based regimen should only be considered in the absence of prior virological failure or resistance mutations to nucleoside reverse transcriptase inhibitors and NNRTIs to avoid virological failures.

Abstract
Objective To assess, in a clinical cohort, the efficacy of switching treatment in virologically-suppressed patients to tenofovir/emtricitabine/rilpivirine as a single-tablet regimen (STR) using the PCR signal of the viral load (VL) assay and plasma drug determination (C24h). Patients and methods An observational single-centre study enrolling patients with VL<50 copies/mL initiating rilpivirine-based STR. C24h and VL were performed until W48 and W96 of STR, respectively. PCRneg was defined as an undetected PCR signal. Medians (IQR) were presented. Results 116 patients were enrolled. At STR baseline, time since first antiretroviral therapy and time of virological suppression were 6 years (2–9) and 17 months (7–43), respectively. Before STR initiation, patients were receiving protease inhibitors and non-nucleoside reverse transcriptase inhibitors-based regimen in 44% and 47% of cases, respectively. Historical genotype showed virus resistant to one drug of the STR in 6 patients (5%). At W96, 17 (15%) discontinued STR due to adverse events. The proportion of patients maintaining VL <50 copies/mL on treatment was 98%, 99%, 100%, 100%, 100% and 100% at W12, W24, W36, W48, W72 and W96, respectively. Among them, 70%, 66%, 68%, 59%, 74%, 68% and 60% were PCRneg at baseline, W12, W24, W36, W48, W72 and W96, respectively. Median rilpivirine C24h was 91 ng/mL (57–141, n = 285), with 91% of rilpivirine C24h >50 ng/mL, the target effective concentration. Conclusions In this clinical cohort of virologically-suppressed patients switching to a new STR, most subjects had adequate rilpivirine C24h and displayed a high level of virological suppression with no residual viremia until W96.

Efficacy and safety in clinical practice of a rilpivirine, tenofovir and emtricitabine single-tablet regimen in virologically suppressed HIV-positive patients on stable antiretroviral therapy. J Int AIDS Soc 2015; 18:20037. [PMID: 26232000 PMCID: PMC4522018 DOI: 10.7448/ias.18.1.20037] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2015] [Revised: 06/24/2015] [Accepted: 07/06/2015] [Indexed: 12/14/2022] Open
Abstract
INTRODUCTION Switching to a rilpivirine, tenofovir and emtricitabine (RTE) single-tablet regimen (STR) has been evaluated in a limited number of virologically suppressed patients. The aim of this study was to describe clinical outcomes in HIV-positive patients switched from a suppressive antiretroviral regimen to RTE STR in routine clinical practice. METHODS In this retrospective study of antiretroviral-treated patients with <50 copies of HIV RNA/mL switched to RTE STR, virological failure (VF) was defined as two consecutive measurements of ≥50 copies/mL or a single measurement of ≥50 copies/mL followed by any change in treatment. Treatment failure (TF) was defined as VF or discontinuation of the STR for any reason. Univariate mixed-linear models were used to identify differences in laboratory parameters over time. RESULTS AND DISCUSSION The analysis involved 307 patients (83% males) with a median age of 45.8 years (interquartile range (IQR 39.3-50.9), who were followed up for a median of 7.4 months (IQR 4.6-10.9). VF occurred in three patients (1%) switched from a protease inhibitor (PI)-based regimen, after a median of 2.6 months (IQR 1.6-3.0), and TF in 34 patients (11%) after a median of three months (IQR 1.4-5.8), 24 of whom (71%) were receiving a PI-based regimen at baseline. Overall, there was a slight but statistically significant improvement in the mean monthly change from baseline in CD4+ cell counts (p=0.027), the CD4+/CD8+ ratio (p=0.0001), and Hb (p=0.024), alanine amino transferase (ALT) (p=0.009), total bilirubin (p<0.0001), indirect bilirubin (p<0.0001), total cholesterol (p<0.0001) and triglyceride (p<0.0001) levels. There was also a slight but statistically significant increase in serum creatinine (p=0.0004), aspartate amino transferase (AST) (p=0.001) and liver fibrosis index (FIB-4) (p=0.002), and a decrease in eGFRcreat (p<0.0001) and high-density lipoprotein (HDL) cholesterol (p<0.0001) values. The study limitations include its retrospective design, the relatively short follow-up, and the absence of data concerning the severity of clinical adverse events; however, it does provide new information concerning the laboratory changes that occur in patients switching from PI-based or PI-sparing regimens to RTE STR. CONCLUSIONS The study findings confirm the efficacy and safety in clinical practice of switching to RTE STR in virologically suppressed patients receiving other antiretrovirals.
