653 – TFV-DP Is Associated With Baseline Virologic Suppression in PWH on TAF: Results From ACTG A5359

Background Tenofovir (TFV)-diphosphate (TFV-DP) concentrations in dried blood spots (DBS) demonstrate strong associations with adherence, virologic suppression (VS) and future viremia in persons with HIV (PWH) but data are limited to the older TFV prodrug or PWH with VS on TFV alafenamide (TAF). We examined TFV-DP in DBS and its association with VS at baseline among…

709 – Trosunilimab Safety, Pharmacokinetics, and Pharmacodynamics in People With and Without HIV-1

Background ART-free HIV viral control remains an unmet need for people with HIV (PWH). Trosunilimab, an anti-α4β7 integrin antibody with preserved Fc functionality, is expected to induce immune responses to control viral replication, and was evaluated in a phase 1 program in healthy volunteers (HV) and PWH. Methods The double-blind, placebo (PBO) controlled phase 1…

701 – A 24-Week Phase II Maintenance Study of TMB-365/TMB-380 Q8W in People With Suppressed HIV-1 Infection

Background TMB-365, a second-generation post-attachment bNAb binds to the second domain of CD4 and displays improved PK, antiviral activity, and breadth of coverage when compared to ibalizumab. TMB-380 (VRC07-523LS) is a bNAb that binds to the CD4 binding site of HIV Env and has potent antiviral activity and favorable safety and PK profile. Here we…

658 – Integrase Inhibitor- Versus Protease Inhibitor-Based Therapy for People With Advanced HIV Disease

Background To date clinical trials have been underpowered to assess the preferred antiretrovirals in therapy-naïve people with advanced HIV disease (PWAH). We investigated the efficacy and safety of an integrase inhibitor (INI) versus a boosted protease inhibitor (PI) containing regimen in PWAH. Methods In this open-label, randomised, multicentre, non-inferiority trial, therapy-naive people with HIV aged…

720 – Optimal Timing and Immunogenicity of COVID-19 Booster Vaccination: The EU-COVAT-2 BOOSTAVAC Trial

Background Currently, optimal timing and/or number of booster COVID19 vaccinations remains unclear. We compared immunogenicity and safety of mRNA booster vaccination at different time intervals. Methods In a randomised, controlled, multicentre, phase II trial, adults with >3 prior mRNA COVID19 vaccines, with last vaccine 3 to 7 months (M) prior, were randomized to one of…

690 – Long-Acting Injectable ART in Persons With HIV-1 Viremia in the South: A Tool to End the Epidemic

Background Treatment with long-acting antiretroviral therapy (LA ART) with cabotegravir/rilpivirine (CAB/RPV) +/- lenacapavir (LEN) holds promise to achieve viral suppression (VS) in people with HIV (PWH) for whom oral ART fails. Although supported in certain scenarios by guidelines, scaling this approach in viremic PWH has lagged Methods We performed a retrospective review of PWH cared for…

719 – Metformin on Time to Sustained Recovery in Adults With COVID-19: ACTIV-6 Randomized Clinical Trial

Background The effect of metformin on reducing symptom duration among low-risk, outpatient adults with mild to moderate coronavirus disease 2019 (COVID-19) has not been studied. Our objective was to test metformin compared to placebo for symptom resolution during acute infection with SARS-CoV-2.  Methods The ACTIV-6 platform clinical trial evaluated repurposed medications for mild to moderate…

748 – Safety and Efficacy of 8-Week Glecaprevir/Pibrentasvir for Acute HCV in People Living With HIV

Background Globally there are up to 2.3 million people living with HIV (PLHIV) and hepatitis C virus (HCV) co-infection. PLHIV with HCV co-infection are at high risk for liver-related morbidity and mortality. There are currently no approved direct acting antivirals (DAA) for acute HCV infection; however, glecaprevir/pibrentasvir (G/P) has been well studied in chronic HCV…

779 – A New Point-of-Care Ultrasound Protocol for Chronic Hepatitis B and HBV/HIV Coinfection in Zambia

Background Background: Point-of-care ultrasound (POCUS) has emerged globally as inexpensive tool used by various healthcare professionals. We evaluated the accuracy of a novel point-of-care liver ultrasound protocol for hepatitis (PUSH) in detecting significant fibrosis, cirrhosis, and suspicious liver lesions in Zambia.  Methods Method: we performed a real-world validation of the PUSH at University Teaching hospital in Lusaka, Zambia, from March…

797 – Vascular Endothelial Growth Factor Receptor 3 (VEGFR3/FLT4) Regulates the KSHV Replication Cycle

Background Kaposi sarcoma-associated herpesvirus (KSHV) is the etiologic agent of the AIDS-defining cancer Kaposi sarcoma (KS). Despite widespread use of antiretroviral therapy, KSHV seroprevalence remains at 40% in HIV+ individuals in the US. HIV infection promotes KS development via angiogenic and pro-inflammatory factors and KSHV infection drives angiogenesis as observed in highly vascularized KS lesions…
