ACTG 5391

Doravirine for Persons with Excessive Weight Gain

on Integrase Inhibitors and Tenofovir Alafenamide

Purpose of this Investigational Study: 


We want to understand why some people gain excessive weight while taking HIV treatment, and whether switching the HIV treatment regimen can help.


Body weight can change throughout our lifetime and is influenced by multiple factors.


Previous studies showed that people living with HIV may gain more weight when taking an integrase inhibitor, especially with tenofovir alafenamide (TAF). When compared to other regimens, these studies also showed that women and African Americans were disproportionately impacted by weight changes while on HIV treatment with integrase inhibitors.

The DO IT study will answer these important questions for individuals who have gained substantial weight while taking an integrase inhibitor (bictegravir [BIC], dolutegravir [DTG], or raltegravir [RAL]) with TAF.


It is designed to compare weight change for those who either stay with their current regimen or switch to a regimen with doravirine (DOR).


There will be three groups:


          Group 1: DOR + TAF/FTC


          Group 2: DOR + TDF/FTC


          Group 3: will continue on their current treatment regimen

Understanding Excessive Weight Gain on Newer HIV Treatments

The topic of our June 2021 Community Advisory Board (CAB) meeting was about the excessive weight gain on the newer HIV regimens containing Biktarvy, Tivicay, Isentress or Descovy.


Dr. Brian Wood answers our questions and explains the DO-IT Study to us--a clinical trials that seeks to investigate why this weight gain is happening and if we can reverse it.
