Long-Acting/Extended Release (LA/ER) Antiretroviral Research Resource Program (LEAP) Investigator Meeting & Annual Workshop - 2021


Friday March 5, 2021

The Long-Acting Extended Release Antiretroviral Research Resource Program (LEAP) virtually convened clinicians, investigators, developers, community advocacy groups, not-for-profit institutions and regulatory authorities. Attendees shared their diverse perspectives and discussed updates, challenges and future directions in the development of LA formulations. The meeting served as a forum to collectively advance the long-acting field. The Workshop consisted of two Plenary Sessions and four Focus Groups. Below, you’ll find links to video recordings and text summaries of the Plenary and Focus Group presentations.
