Lenacapavir Intensification to Disrupt HIV Reservoirs in Virologically Suppressed People With HIV Receiving Antiretroviral Therapy

Background: Antiretroviral viral therapy (ART) allows people with human immunodeficiency (HIV) to live long, healthy lives. But ART is not a cure. HIV can remain in the body, in infected cells called reservoirs. If a person stops taking ART, the HIV can rebound and reach high levels in their blood. Researchers want to find ways to reduce the size of HIV reservoirs in people taking ART. Objective: To test a drug (lenacapavir) in people with HIV who are on effective ART. Lenacapavir, also called Sunlenca, is already approved for use in people with HIV who cannot be treated with standard ART. Eligibility: People aged 18 to 75 years with HIV that has been suppressed for at least 3 years with ART. Design: Participants will have 13 clinic visits over 2 years. Participants will be screened. They will have a physical exam with blood tests. They will maintain their ART throughout the study. Participants will undergo leukapheresis up to 6 times. Blood will be drawn via a tube in an arm. The blood will pass through a machine that separates out the white blood cells. The remaining blood will be returned to the body through a second tube. Two-thirds of participants will take lenacapavir in addition to their regular ART. They will receive the drug as an injection under the skin 3 times at 6-month intervals. They will also take lenacapavir as 2 pills swallowed by mouth on the first 2 days of the study. ...
