FDA Approves First Once-a-Month Injectable Drug Regimen for People Living with HIV The FDA this week approved the use of once-a-month injectable Cabenuva for people living with HIV. The FDA reports: “The U.S. Food and Drug Administration today approved Cabenuva (cabotegravir and rilpivirine, injectable formulation) as a complete regimen for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in adults to replace a current antiretroviral regimen in those who are virologically suppressed on a stable antiretroviral regimen with no history of treatment failure and with no known or suspected resistance to either cabotegravir or rilpivirine. This is the first FDA-approved injectable, complete regimen for HIV-infected adults that is administered once a month.”
