NIH celebrates FDA approval of long-acting injectable drug for HIV prevention

The FDA approval is based on data primarily from two NIH-supported clinical trials, HPTN 083 and HPTN 084. Both trials compared the safety and effectiveness of a PrEP regimen containing long-acting injectable cabotegravir with a regimen of daily oral PrEP. HPTN 083 enrolled more than 4,500 cisgender men who have sex with men and transgender women who have sex with men in Argentina, Brazil, Peru, South Africa, Thailand, the United States and Vietnam. HPTN 084 enrolled more than 3,200 cisgender women in Botswana, Eswatini, Kenya, Malawi, South Africa, Uganda and Zimbabwe. The two trials found that both HIV prevention methods were safe and highly effective, but injectable cabotegravir was more effective than daily oral PrEP at preventing HIV acquisition.

The HPTN 083 and HPTN 084 trials were sponsored by NIAID and conducted by the NIH-funded HIV Prevention Trials Network (HPTN). NIAID and ViiV Healthcare co-funded both trials; the Bill & Melinda Gates Foundation also supported HPTN 084. HPTN is co-funded by NIAID, the National Institute of Mental Health, the National Institute on Drug Abuse, and the Eunice Kennedy Shriver National Institute of Child Health and Human Development, all part of NIH.

NIAID conducts and supports research—at NIH, throughout the United States, and worldwide—to study the causes of infectious and immune-mediated diseases, and to develop better means of preventing, diagnosing and treating these illnesses. News releases, fact sheets and other NIAID-related materials are available on the NIAID website.
