This study is looking for people living with HIV who have never taken ARVs  and have a CD4 count above 350 and HIV viral load between 5,000 and 100,000, and are willing to start ARVs by day 28 of the study.

About this Study

This study will evaluate the safety and  effectiveness of an investigational monoclonal antibody given by infusion, SAR441236 (versus placebo in ARM A).


The study will also see if  SAR441236 can reduce HIV in a person’s blood and measure the antibody in blood over time.

Both people with well controlled HIV infection (Arm A) and those with HIV infection not on antiretroviral therapy (ART) (Arm B) will be enrolled. People not on ART will begin medications within 28 days.


ARM A: Participants will be randomized (like flipping a coin) to receive SAR441236 or a placebo.  One group will receive an infusion/placebo every 12 weeks x 4. This arm is now full!

ARM B: All participants will receive SAR441236 and begin ARVs by day 28.
