People with HIV at the end of life and their next-of-kin/loved ones are willing to participate in interventional HIV cure-related research.

The Last Gift study at the University of California San Diego, United States enrolls terminally ill people with HIV (PWH) in HIV cure research. From 2017 - 2022, we conducted surveys with Last Gift participants and their next-of-kin/loved ones to evaluate willingness to participate in different types of HIV cure research at the end of life. We analyzed willingness data descriptively. We surveyed 17 Last Gift participants and 17 next-of-kin/loved ones. More than half of Last Gift participants (n = 10; 58.8%) expressed willingness to participate in studies involving totally new treatments or approaches ("first-in-human" studies), a combination of different approaches, the use of unique antibodies, proteins or molecules, or therapeutic vaccines. Under one-quarter of Last Gift participants (n = 4; 23.5%) expressed willingness to participate in research involving interventions that may shorten their life expectancy to benefit medical research. Most Last Gift participants and their next-of-kin/loved ones also expressed high acceptance for various types of donations and biopsies at the end of life (e.g., hair donations and skin, lymph node or gut biopsies). Knowing whether people would be willing to participate in different types of EOL HIV cure research can help inform the design of future innovative studies. As a research community, we have a duty to design studies with adequate safeguards to preserve the public trust in research and honor PWH's important gift to humanity.
