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 four Plenary Sessions and four Focus Groups.
