Efficacy, Safety, and Tolerability of Switching From Bictegravir/Emtricitabine/Tenofovir Alafenamide to Dolutegravir/Lamivudine Among Adults With Virologically Suppressed HIV: The DYAD Study.

Background: In TANGO and SALSA, switching to dolutegravir/lamivudine (DTG/3TC) was noninferior to continuing a baseline regimen among adults who were treatment experienced, although few switched from bictegravir (B) / emtricitabine (F) / tenofovir alafenamide (TAF). Here, we present the efficacy and safety of switching to DTG/3TC as compared with continuing with B/F/TAF among adults with virologic suppression.

Methods: DYAD is an open-label clinical trial that randomized adults with HIV-1 RNA <50 copies/mL and no prior virologic failure (2:1) to switch to once-daily fixed-dose DTG/3TC or maintain B/F/TAF.

Safety and antiviral effect of a triple combination of HIV-1 broadly neutralizing antibodies: a phase 1/2a trial.

Human immunodeficiency virus type 1 (HIV-1)-specific broadly neutralizing monoclonal antibodies (bNAbs) have to date shown transient viral suppression when administered as monotherapy or as a cocktail of two antibodies. A combination of three bNAbs provides improved neutralization coverage of global viruses, which may more potently suppress viral escape and rebound. Here we performed an open-label, two-part study evaluating a single intravenous dose of HIV-1 bNAbs, PGT121, PGDM1400 and VRC07-523LS, in six adults without HIV in part 1 and a multicenter trial of up to six monthly infusions of these three bNAbs in 12 people living with HIV with an antiretroviral therapy (ART) interruption in part 2.

Racial/ethnic disparities in HIV care outcomes among insured patients at a large urban sexual health clinic.

Prior studies demonstrate that non-White patients are less likely to achieve human immunodeficiency virus (HIV) suppression compared to White patients due to lack of health insurance. This study aims to determine whether racial disparities in the HIV care cascade persist among a cohort of privately and publicly insured patients. This retrospective analysis evaluated HIV care outcomes during the first year of care.

Sustained Virologic Suppression With Dolutegravir/Lamivudine in a Test-and-Treat Setting Through 48 Weeks.

Background: We assessed the efficacy and safety of dolutegravir/lamivudine (DTG/3TC) in a US test-and-treat setting at a secondary 48-week time point of the multicenter, single-arm, phase IIIb STAT study.

Methods: Participants were eligible adults newly diagnosed with human immunodeficiency virus (HIV)-1 and had started once-daily DTG/3TC within 14 days of diagnosis, before laboratory results were available. Antiretroviral therapy (ART) was modified if baseline testing indicated DTG or 3TC resistance, hepatitis B virus (HBV) coinfection, or creatinine clearance <30 mL/min per 1.

Treatment-related early discontinuations and adverse events among newly diagnosed people living with HIV initiating integrase inhibitors in a real-world setting.

Background: Cohort studies suggest higher discontinuation rates with integrase strand transfer inhibitors (INSTIs) than are seen in clinical trials. We assessed discontinuations and adverse events (AEs) that were considered related to the initial INSTI in the first year following initiation among treatment-naïve people living with HIV (PLWH).

Methods: Newly diagnosed PLWH initiating raltegravir, elvitegravir/cobicistat, dolutegravir or bictegravir in combination with emtricitabine/tenofovir alafenamide or emtricitabine/tenofovir disoproxil fumarate between 10/2007 and 1/2020 at the Orlando Immunology Center were included.

Safety and antiviral activity of triple combination broadly neutralizing monoclonal antibody therapy against HIV-1: a phase 1 clinical trial.

HIV-1 therapy with single or dual broadly neutralizing antibodies (bNAbs) has shown viral escape, indicating that at least a triple bNAb therapy may be needed for robust suppression of viremia. We performed a two-part study consisting of a single-center, randomized, double-blind, dose-escalation, placebo-controlled first-in-human trial of the HIV-1 V2-glycan-specific antibody PGDM1400 alone or in combination with the V3-glycan-specific antibody PGT121 in 24 adults without HIV in part 1, as well as a multi-center, open-label trial of the combination of PGDM1400, PGT121 and the CD4-binding-site antibody VRC07-523LS in five viremic adults living with HIV not on antiretroviral therapy (ART) in part 2 ( NCT03205917 ). The primary endpoints were safety, tolerability and pharmacokinetics for both parts and antiviral activity among viremic adults living with HIV and not on ART for part 2 of the study.

Safety, pharmacokinetics and antiviral activity of PGT121, a broadly neutralizing monoclonal antibody against HIV-1: a randomized, placebo-controlled, phase 1 clinical trial.

Human immunodeficiency virus (HIV)-1-specific broadly neutralizing monoclonal antibodies are currently under development to treat and prevent HIV-1 infection. We performed a single-center, randomized, double-blind, dose-escalation, placebo-controlled trial of a single administration of the HIV-1 V3-glycan-specific antibody PGT121 at 3, 10 and 30 mg kg in HIV-uninfected adults and HIV-infected adults on antiretroviral therapy (ART), as well as a multicenter, open-label trial of one infusion of PGT121 at 30 mg kg in viremic HIV-infected adults not on ART (no. NCT02960581).

Real-world efficacy and safety of switching to bictegravir/emtricitabine/tenofovir alafenamide in older people living with HIV.

Approximately 50% of people living with HIV (PLWH) in the United States are ≥50 years old. Clinical trials of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) demonstrated potent efficacy and favorable safety in older PLWH; however, real-world data would be useful to validate these results.Retrospective cohort study.

Dolutegravir/lamivudine as a first-line regimen in a test-and-treat setting for newly diagnosed people living with HIV.

Objectives: Dolutegravir/lamivudine (DTG/3TC) is indicated for treatment-naive and experienced people with HIV; however, questions remain about its utility in a test-and-treat setting because of potential transmitted resistance and baseline hepatitis B virus (HBV) co-infection. We present feasibility and efficacy of DTG/3TC in newly diagnosed individuals in a test-and-treat setting.

Design: The single-arm STAT study evaluated DTG/3TC in a US test-and-treat setting.

Virologic outcomes of switching to dolutegravir functional mono- or dual therapy with a non-cytosine nucleoside analog: a retrospective study of treatment-experienced, patients living with HIV.

Background: Dolutegravir (DTG) monotherapy results in virologic failure and the development of DTG resistance. Here, we evaluated virologic outcomes of patients switched to DTG functional mono- or dual therapy with a non-cytosine nucleoside analog (NA).

Methods: This retrospective, single center study included treatment-experienced patients switched to regimens containing ≥ 2 antiretrovirals between 8/13/13-11/22/14 who were later found to be on DTG functional mono- or dual therapy with a non-cytosine NA based on historical genotypes.

Clinical outcomes of HIV-1 infected patients switched from complex multi-tablet regimens to tenofovir alafenamide based single-tablet regimens plus a boosted protease inhibitor in a real-world setting.

Background: Multi-tablet regimens (MTRs) are associated with increased adverse events and non-adherence. Single tablet regimens (STRs) plus boosted protease inhibitors (PIs) are a simplification option for MTR-treated patients; however, data is needed to validate this therapeutic strategy.

Methods: This retrospective analysis included all HIV-1 infected patients seen at a single center from March 2016 to December 2017 who were switched from twice-daily (BID) regimens or regimens containing ​≥ ​3 pills daily to elvitegravir/cobicistat/emtricitabine/tenofovir-alafenamide (E/C/F/TAF) plus darunavir (DRV) or rilpivirine/emtricitabine/tenofovir-alafenamide (RPV/F/TAF) plus DRV boosted with ritonavir or cobicistat (DRV/r-c).

Determinants of pre-exposure prophylaxis (PrEP) persistence in a high-risk population in Central Florida.

Orlando has the second highest HIV incidence in the USA. Tenofovir disoproxil fumarate/emtricitabine is approved as pre-exposure prophylaxis (PrEP) to minimize HIV transmission. Our study describes the PrEP care continuum and factors impacting PrEP persistence during the first year of PrEP care at a sexual health clinic in Orlando.

Clinical outcomes of once-daily darunavir in treatment-experienced patients with darunavir resistance-associated mutations through 48 weeks of treatment.

Darunavir (DRV) is approved for once-daily use in patients with no DRV resistance-associated mutations (RAMs) and twice-daily use in those with DRV RAMs. Several studies suggest that once-daily DRV retains efficacy in the setting of 1-2 DRV RAMs whereas three or more DRV RAMs are needed for DRV resistance. There are few data to support the long-term use of once-daily DRV in patients with DRV RAMs.

Pre-exposure Prophylaxis Uptake and Discontinuation Among Young Black Men Who Have Sex With Men in Atlanta, Georgia: A Prospective Cohort Study.

Background: Human immunodeficiency virus (HIV) preexposure prophylaxis (PrEP) has great potential to reduce HIV incidence among young black men who have sex with men (YBMSM); however, initiation and persistence for this group remain low. We sought to understand the patterns and predictors of PrEP uptake and discontinuation among YBMSM in Atlanta, Georgia.

Methods: PrEP was offered to all participants in a prospective cohort of YBMSM aged 18-29 years not living with HIV.

PrEP Implementation and Persistence in a County Health Department Setting in Atlanta, GA.

For marginalized populations, county health departments may be important PrEP access points; however, there are little data on successful PrEP programs at these venues outside of incentivized demonstration projects. Therefore, we implemented an open-access, free PrEP clinic at a county health department in Atlanta, GA to promote PrEP uptake among high-risk clients. The Fulton County Board of Health PrEP clinic launched in October 2015, and eligible clients who expressed interest initiated PrEP and attended follow-up visits per CDC guidelines.

Contrasting Self-Perceived Need and Guideline-Based Indication for HIV Pre-Exposure Prophylaxis Among Young, Black Men Who Have Sex with Men Offered Pre-Exposure Prophylaxis in Atlanta, Georgia.

Despite high HIV incidence among young black men who have sex with men (YBMSM), pre-exposure prophylaxis (PrEP) uptake in this group is low. In a cohort of HIV-negative YBMSM in Atlanta, GA, all participants were offered PrEP as standard of care with free clinician visits and laboratory testing. We explored self-perceived need for PrEP among 29 in-depth interview participants by asking about reasons for PrEP uptake or refusal and factors that may lead to future reconsideration.

Beyond the Biomedical: Preexposure Prophylaxis Failures in a Cohort of Young Black Men Who Have Sex With Men in Atlanta, Georgia.

Human immunodeficiency virus (HIV) preexposure prophylaxis (PrEP) has high biomedical efficacy; however, awareness, access, uptake, and persistence on therapy remain low among black men who have sex with men (BMSM), who are at highest risk of HIV in the United States. To date, discussions of "PrEP failure" have focused on one typology: rare, documented HIV acquisitions among PrEP users with adequate serum drug levels (ie, biomedical failure). In our cohort of HIV-negative young BMSM in Atlanta, Georgia, we continue to observe a high HIV incidence (6.

Challenges in Translating PrEP Interest Into Uptake in an Observational Study of Young Black MSM.

Background: HIV incidence among US young, black men who have sex with men (YBMSM) is high, and structural barriers (eg lack of health insurance) may limit access to Pre-exposure prophylaxis (PrEP). Research studies conducted with YBMSM must ensure access to the best available HIV prevention methods, including PrEP.

Methods: We implemented an optional, nonincentivized PrEP program in addition to the standard HIV prevention services in a prospective, observational cohort of HIV-negative YBMSM in Atlanta, GA.

Willingness to use pre-exposure prophylaxis among Black and White men who have sex with men in Atlanta, Georgia.

PrEP willingness may be different among black and white men who have sex with men (MSM) given known disparities in HIV incidence, sociodemographic factors, and healthcare access between these groups. We surveyed 482 black and white HIV-negative MSM in Atlanta, GA about their willingness to use pre-exposure prophylaxis (PrEP) and facilitators and barriers to PrEP willingness. Overall, 45% (215/482) of men indicated interest in using PrEP.
