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.

Bictegravir/emtricitabine/tenofovir alafenamide in adults with HIV-1 and end-stage kidney disease on chronic haemodialysis.

Introduction: Treatment for people with HIV-1 and end-stage kidney disease (ESKD) on haemodialysis (HD) has previously required complex dose-adjusted regimens, with limited data on the use of a single-tablet regimen in this population. Our aim was to assess the efficacy and safety of once-daily bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) and to evaluate the pharmacokinetics of bictegravir (BIC) in adults with HIV-1 and ESKD on HD.

Methods: We performed an open-label extension (OLE) of an open-label, multicentre, single-group phase 3b study (NCT02600819) of adults with ESKD on HD and HIV-1 with virological suppression.

A Pooled Analysis of Eight Clinical Studies Suggests a Link Between Influenza-Like Symptoms and Pharmacodynamics of the Toll-Like Receptor-7 Agonist Vesatolimod.

Introduction: Vesatolimod is a Toll-like receptor-7 (TLR7) agonist in clinical development as part of a combination regimen for human immunodeficiency virus (HIV) cure. Influenza-like symptoms associated with TLR7-mediated immune activation have been reported in clinical trials of vesatolimod. Therefore, a broader understanding of the safety profile of vesatolimod and association with dose and mechanism of action will help inform future clinical studies.

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.

Efficacy and safety of two fixed doses of ibalizumab plus optimized background regimen in treatment-experienced HIV-positive individuals.

Background: Sustained viral suppression in patients with multidrug-resistant (MDR) human immunodeficiency virus (HIV) infection remains difficult; accordingly, agents targeting different steps in the HIV life cycle are needed. Ibalizumab, a humanized immunoglobulin G4 monoclonal antibody, is a cluster of differentiation (CD4)-directed post-attachment inhibitor.

Methods: In this Phase IIb study, 113 individuals with MDR HIV-1 and limited treatment options were assigned an optimized background regimen (OBR) and randomized to either 800 mg ibalizumab every two weeks (q2wk; n=59) or 2,000 mg ibalizumab every four weeks (q4wk; n=54) up to Week 24.
