Events of Note

‘Thinking Beyond Lifelong Treatment in HIV’, 18 July, 19:00 – 20:30 CET

A unique opening day session convening community members, researchers, people living with HIV, and partners to examine the process of developing a functional cure for HIV. During the symposium, they will discuss how pursuing a multi-pronged approach to long-term viral remission in the absence of ongoing antiretroviral treatment will be a critical component of making progress toward this goal, and the critical role community collaboration will play. We’re honored to be joined by clinical trial participants, who will share critical insights about what it’s like to be part of a trial and what they’d like researchers to understand about their experiences. Our very own Devi SenGupta, head of Gilead’s HIV Cure Development Program, is joined by:

  • Dr. Marina Caskey, The Rockefeller University
  • Matthew Chappell, Stanford Health Care
  • Cecilia Chung, Transgender Law Center
  • Dr. Steve Deeks, University of California, San Francisco
  • Dr. Karine Dubé, University of North Carolina, Chapel Hill
  • Nombuso Msomi, FRESH: Females Rising through Education, Support and Health
  • Dr. Thumbi Ndung’u, Africa Health Research Institute
  • Moses “Supercharger” Nsubuga, Joint Adherent Brothers and Sisters Against AIDS
  • Dr. Robert F. Siliciano, Howard Hughes Medical Institute, Johns Hopkins University
  • Dr. Ole Søgaard, Aarhus University Hospital

Registered IAS attendees are invited to watch the symposium on the IAS platform.

‘Community Talks’, July 29, 2021

Community representatives from around the world come together post-IAS to delve into key takeaways and hot topics stemming from the conference. They’ll also be discussing how these data findings will impact the HIV community at large. This forum allows for unique members of the community to collaborate and have an open discussion.
