Quick Navigation

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

A5388 is a phase II, two-arm, randomized, double-blind, placebo-controlled study that will enroll 48 antiretroviral therapy (ART)-naïve adults with acute HIV infection (AHI) in order to determine whether: * Administration of combination HIV-specific broadly neutralizing antibody (bNAb) therapy in addition to ART during acute HIV infection (AHI) will be safe. * Participants who receive combination bNAb therapy in addition to ART during AHI will be more likely to demonstrate a delay in time to HIV-1 RNA ≥1,000 copies/mL for 4 consecutive weeks compared to participants who receive placebo plus ART. * Participants who receive combination bNAb therapy in addition to ART during AHI will demonstrate lower viral reservoirs and enhanced HIV-specific immunity compared to participants who receive placebo plus ART.
