Long-term effectiveness, safety, and tolerability of doravirine in antiretroviral-experienced people with HIV in real life. Microbiol Spectr 2024; 12:e0065424. [PMID: 38916326 PMCID: PMC11302240 DOI: 10.1128/spectrum.00654-24] [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: 04/22/2024] [Accepted: 05/21/2024] [Indexed: 06/26/2024] Open
Abstract
Real-life data on doravirine (DOR) in different drug combinations are limited. We evaluated the effectiveness of DOR plus two nucleos(t)ide reverse transcriptase inhibitors (NRTI), mainly abacavir/lamivudine, and dual therapies in people with HIV (PWH), mostly virologically suppressed. Ambispective observational study that enrolled adults PWH who initiated a DOR-based regimen from September 2020 to February 2022 at a referral center in Spain. Participants were grouped as follows: A, received DOR plus two NRTI; B, dual therapy (DT) with DOR plus dolutegravir (DTG) or darunavir/cobicistat (DRVc); C, DOR plus ≥two antiretroviral drugs. The primary endpoints were treatment effectiveness at week 48 by intention-to-treat (ITT) and per-protocol analysis (OT). A cohort of 187 participants, 91% virologically suppressed, were analyzed after a median follow-up of 112 weeks (80-136). Group A received DOR plus abacavir/lamivudine (ABV/3TC) (n = 109) or tenofovir/emtricitabine (TFV/3TC) (n = 45). At week 48, the effectiveness of DOR plus ABV/3TC by ITT was 90.8% (CI95, 88.0-93.6), better than with TFV/FTC [73.3% (66.7-79.9); P = 0.003]. Only one virologic failure was observed. Mild adverse effects were the cause of treatment discontinuation in 7.8%, followed by switching to a single-tablet regimen. In group B, the effectiveness by ITT was 92.9% (CI95, 88.0-97.8) at week 48. No adverse effects or virologic failure were registered in this group. DOR plus two NRTI or DT have long-term effectiveness and safety as a switching option for PWH, mostly virologically suppressed. The DOR plus ABV/3TC combination has shown even better effectiveness than TFV/FTC.IMPORTANCEDOR-based regimens have shown long-term effectiveness and safety in PWH, mostly virologically suppressed. The combination of DOR plus ABV/3TC has shown even better safety and effectiveness than TFV/FTC. DOR plus two NRTI offers cost benefits compared to other regimens.

Abstract
Objective To compare the long-term effects on immune parameters, inflammation, and HIV-1 reservoir after switching to a two-drug (2DR) versus maintaining an integrase inhibitor (InSTI)-based three-drug regimen (3DR). Methods Cross-sectional study in which HIV-1 treatment-naïve people started and maintained an InSTI-based 3DR or, at different times, switched to 2DR (dolutegravir or darunavir/cobicistat + lamivudine). CD4+ and CD8+ T-cell activation and exhaustion, plasma concentrations of hs-CRP, D-dimer, P-selectin, IL-1β, IL-6, TNF-α, IFN-γ, IP-10, sTNFR-I/II, MIP-1α/β, I-FABP, LBP, sCD14, sCD163, MCP-1, and cellular-associated HIV-1-DNA and -RNA were quantified by flow cytometry, different immunoassays, and droplet digital PCR, respectively. The U de Mann-Whitney test evaluated differences between 3DR and 2DR. Immune recovery was evaluated using a general linear model for repeated measures adjusted for different co-variables. Results Fifty participants per group were included. The median time on 3DR was 82 months for the 3DR group and 30 months for the 2DR group, after which it switched to 2DR for a median of 57 months. We did not find differences between both groups in any of the parameters analyzed. Specifically, some values in 3DR and 2DR were hs-CRP, 0.92 mg/L (0.45-2.23) vs. 1.23 (0.61-2.38); D-dimer, 190.0 µg/L (150.0-370.0) vs. 190.0 (150.0-397.5); IL-6, 2.8 pg/mL (1.3-5.3) vs. 3.2 (2.1-4.7); sCD14, 4.5 ng/mL (3.3-6.2) vs. 5.0 (3.6-6.1), respectively, all p ≥ 0.399. Conclusion In the long term, switching to 2DR does not negatively affect immunologic parameters, inflammatory markers, or HIV-1 reservoir. Clinical trial registration identifier NCT04076423.

Abstract
Point-of-care (POC) HIV viral load (VL) tests are needed to enhance access to HIV VL testing in low- and middle-income countries (LMICs) and to enable HIV VL self-testing at home, which in turn have the potential to enhance the global management of the disease. While methods based on real-time reverse transcription-polymerase chain reaction (RT-PCR) are highly sensitive and quantitatively accurate, they often require bulky and expensive instruments, making applications at the POC challenging. On the other hand, although methods based on isothermal amplification techniques could be performed using low-cost instruments, they have shown limited quantitative accuracies, i.e., being only semiquantitative. Herein, we present a sensitive and quantitative POC HIV VL quantification method from blood that can be performed using a small power-free three-dimensional-printed plasma separation device and a portable, low-cost magnetofluidic real-time RT-PCR instrument. The plasma separation device, which is composed of a plasma separation membrane and an absorbent material, demonstrated 96% plasma separation efficiency per 100 μL of whole blood. The plasma solution was then processed in a magnetofluidic cartridge for automated HIV RNA extraction and quantification using the portable instrument, which completed 50 cycles of PCR in 15 min. Using the method, we achieved a limit of detection of 500 HIV RNA copies/mL, which is below the World Health Organization's virological failure threshold, and a good quantitative accuracy. The method has the potential for sensitive and quantitative HIV VL testing at the POC and at home self-testing.

Abstract
OBJECTIVES To evaluate whether simplification of antiretroviral treatment to dual therapy (DT) negatively impacts immune recovery (IR), immune activation and inflammation (IA/I), and HIV reservoir. METHODS An open-label, single-centre, randomized controlled trial conducted in adult virologically suppressed HIV-infected patients on triple therapy (TT) with elvitegravir-cobicistat, emtricitabine and tenofovir alafenamide or dolutegravir (DTG), abacavir, and lamivudine (3TC). Participants were randomized to continue TT or switch to DTG, or darunavir/cobicistat (DRVc) plus 3TC. IR was assessed by CD4+/CD8+ ratio at 48 and 96 weeks. Changes in immune activation, proliferation, exhaustion, senescence, and apoptosis in CD4+ and CD8+ T cells, plasma sCD14, hsCRP, D-dimers, β2-microglobulin, IL-6, TNF-α and IP-10 levels, cell-associated HIV-DNA (CA-DNA), and unspliced HIV-RNA (usRNA) were also analysed. RESULTS One hundred and fifty-one participants were enrolled. Fourteen patients did not complete the follow up. In the ITT and PP analysis, the IR was similar between the treatment arms. In the ITT analysis, the median increase in CD4+/CD8+ ratio was 0.10, 0.04, and 0.07 at week 48, and 0.09, 0.05, and 0.08 at week 96 for TT, DTG/3TC, and DRVc/3TC, respectively. After adjusting for confounding factors, the slopes of changes in CD4+/CD8+ ratio over time were independent of treatment (F = 1.699; p = 0.436) and related only to baseline values (F = 756.871; p = 0.000). There were no differences in IA/I, CA-DNA, or usRNA between treatment arms. DISCUSSION Both IR and IA/I, CA-DNA, and usRNA were similar in the three treatment groups, regardless of maintaining TT or simplifying to DTG/3TC or DRVc/3TC in virologically suppressed HIV-infected patients.

Is immune recovery different depending on the use of integrase strand transfer inhibitor-, non-nucleoside reverse transcriptase- or boosted protease inhibitor-based regimens in antiretroviral-naive HIV-infected patients? J Antimicrob Chemother 2021; 75:200-207.

Abstract
OBJECTIVES To analyse whether integrase inhibitor (InSTI)-based regimens achieve better immunological recovery than NNRTI- or boosted PI (bPI)-based regimens as initial ART. METHODS In a retrospective analysis, we selected patients who initiated ART with two NRTIs plus an InSTI, an NNRTI or a bPI and maintained both the same 'third drug' and an HIV-RNA <50 copies/mL in ≥95% of determinations once undetectable viral load had been achieved. We compared CD4+ count, %CD4+ and CD4+/CD8+ ratio recovery over 2 years. Data were analysed using mixed-effects regression models for repeated measures. RESULTS Of the 836 patients included, 208, 481 and 147 initiated with InSTI, NNRTI and bPI, respectively. For CD4+, %CD4+ and CD4+/CD8+ two main slopes were identified: from month 0 to month 6, with the highest increments; and from month 6 to month 24, with smaller increases every semester. Although the patients on InSTI achieved undetectable viral load faster, for CD4+ and %CD4+ there were no differences in the slopes of change according to the third drug either for the first phase (P=0.137 and P=0.393, respectively) or from month 6 onwards (P=0.834 and P=0.159, respectively). The increase in CD4+/CD8+ was slightly higher for bPI compared with InSTI (difference of 0.0119, 95% CI 0.0020-0.0205; P=0.018), but clinically negligible. From month 6 onwards, no differences were found between treatment groups (P=0.176). CONCLUSIONS Immune restoration measured as CD4+ count, %CD4+ and CD4+/CD8+ increases was independent of the third antiretroviral drug class used when given with two NRTIs.

Abstract
This study describes long-term viral load (VL) trajectories and their predictors among women living with HIV (WLWH), using data from Sexual Health and HIV/AIDS: Women's Longitudinal Needs Assessment (SHAWNA), an open prospective cohort study with linkages to the HIV/AIDS Drug Treatment Program. Using Latent Class Growth Analysis (LCGA) on a sample of 153 WLWH (1088 observations), three distinct trajectories of detectable VL (≥50 copies/ml) were identified: 'sustained low probability of detectable VL', characterized by high probability of long-term VL undetectability (51% of participants); 'high probability of delayed viral undetectability', characterized by a high probability VL detectability at baseline that decreases over time (43% of participants); and 'high probability of detectable VL', characterized by a high probability of long-term VL detectability (7% of participants). In multivariable analysis, incarceration (adjusted odds ratio (AOR) = 3.24; 95%CI:1.34-7.82), younger age (AOR = 0.96; 95%CI:0.92-1.00), and lower CD4 count (AOR = 0.82; 95%CI:0.72-0.93) were associated with 'high probability of delayed viral undetectability' compared to 'sustained low probability of detectable VL.' This study reveals the dynamic and heterogeneous nature of WLWH's long-term VL patterns, and highlights the need for early engagement in HIV care among young WLWH and programs to mitigate the destabilizing impact of incarceration on WLWH's HIV treatment outcomes.

Abstract
In order to assess the efficacy of novel HIV-1 treatments leading to a functional cure, the time to viral rebound is frequently used as a surrogate endpoint. The longer the time to viral rebound, the more efficacious the therapy. In support of such an approach, mathematical models serve as a connection between the size of the latent reservoir and the time to HIV-1 rebound after treatment interruption. The simplest of such models assumes that a single successful latent cell reactivation event leads to observable viremia after a period of exponential viral growth. Here we consider a generalization developed by Pinkevych et al. and Hill et al. of this simple model in which multiple reactivation events can occur, each contributing to the exponential growth of the viral load. We formalize and improve the previous derivation of the dynamics predicted by this model, and use the model to estimate relevant biological parameters from SIV rebound data. We confirm a previously described effect of very early antiretroviral therapy (ART) initiation on the rate of recrudescence and the viral load growth rate after treatment interruption. We find that every day ART initiation is delayed results in a 39% increase in the recrudescence rate (95% credible interval: [18%, 62%]), and a 11% decrease of the viral growth rate (95% credible interval: [4%, 20%]). We show that when viral rebound occurs early relative to the viral load doubling time, a model with multiple successful reactivation events fits the data better than a model with only a single successful reactivation event.
