ABX464 Decreases the Total Human Immunodeficiency Virus (HIV) Reservoir and HIV Transcription Initiation in CD4+ T Cells From Antiretroviral Therapy-Suppressed Individuals Living With HIV.

ABSTRACT:

Background

Antiretroviral therapy (ART) intensification and disruption of latency have been suggested as strategies to eradicate HIV. ABX464 is a novel antiviral that inhibits HIV RNA biogenesis. We investigated its effect on HIV transcription and total and intact HIV DNA in CD4+ T cells from ART-suppressed participants enrolled in the ABIVAX-005 clinical trial (NCT02990325).

Methods

Peripheral CD4+ T cells were available for analysis from 9 ART-suppressed participants who were treated daily with 150 mg of ABX464 for 4 weeks. Total and intact HIV DNA and initiated, 5'elongated, unspliced, polyadenylated, and multiply-spliced HIV transcripts were quantified at weeks 0, 4, and 8 using ddPCR.

Results

We observed a significant decrease in total HIV DNA (P = .008, median f
