Material Changes and Developments
- Initiation of Phase III Study: ViiV Healthcare announced the start of the HPTN 083 study, a global Phase III trial evaluating long-acting injectable cabotegravir for HIV pre-exposure prophylaxis (PrEP).
- Study Design: The trial compares cabotegravir injections administered every two months against daily oral Truvada (tenofovir disoproxil fumarate/emtricitabine).
- Target Population: The study aims to enroll 4,500 participants, specifically men who have sex with men and transgender women who have sex with men, across more than 40 sites in North and South America, Asia, and Africa.
- Collaboration: The study is a public-private collaboration involving ViiV Healthcare, the HIV Prevention Trials Network (HPTN), the US National Institute of Allergy and Infectious Disease (NIAID), and Gilead Sciences.
Outlook, Management Commentary, and Risks
Management Commentary: John C. Pottage, Jr., MD, Chief Scientific and Medical Officer at ViiV Healthcare, emphasized the need for prevention options that do not require daily dosing to improve adherence. He noted that while effective HIV treatments exist, reducing transmission rates remains critical to ending the AIDS epidemic by 2030.
Future Outlook: A second Phase III study evaluating long-acting cabotegravir for HIV prevention in young women is anticipated to start in 2017. Primary outcome data for the HPTN 083 study are expected in 2020.
Risks and Contingencies: Cabotegravir is currently an investigational drug and is not approved by regulatory authorities anywhere in the world. The study is designed as a non-inferiority trial; success depends on demonstrating that the injectable regimen is not less effective than the standard daily oral therapy.
