A Community-Driven Framework to Prioritize the Use of Donated Human Biological Materials in the Context of HIV Cure-Related Research at the End of Life
Initiated in 2017 after extensive community engagement, the Last Gift program enrolls altruistic volunteers willing to donate their cells and tissues at the end of life to allow studies on HIV reservoir dynamics across anatomical sites. As the Last Gift team received tissue requests outside the scope of HIV cure research, we noticed the absence of guiding frameworks to help prioritize the use of altruistically donated human biological materials. In this commentary, we present a proposed framework for prioritizing the use of donated human biological materials within and outside the end-of-life (EOL) HIV cure research context, using the Last Gift study as an example. First, we discuss regulatory and policy considerations, and highlight key ethical values to guide prioritization decisions. Second, we present our prioritization framework and share some of our experiences prioritizing requests for donated human biological materials within and outside EOL HIV cure research.
Ethical considerations for HIV cure-related research at the end of life
Abstract
Background
The U.S. National Institute of Allergies and Infectious Diseases (NIAID) and the National Institute of Mental Health (NIMH) have a new research priority: inclusion of terminally ill persons living with HIV (PLWHIV) in HIV cure-related research. For example, the Last Gift is a clinical research study at the University of California San Diego (UCSD) for PLWHIV who have a terminal illness, with a prognosis of less than 6 months.
Discussion
As end-of-life (EOL) HIV cure research is relatively new, the scientific community has a timely opportunity to examine the related ethical challenges. Following an extensive review of the EOL and HIV cure research ethics literature, combined with deliberation from various stakeholders (biomedical researchers, PLWHIV, bioethicists, and socio-behavioral scientists) and our experience with the Last Gift study to date, we outline considerations to ensure that such research with terminally ill PLWHIV remains ethical, focusing on five topics: 1) protecting autonomy through informed consent, 2) avoiding exploitation and fostering altruism, 3) maintaining a favorable benefits/risks balance, 4) safeguarding against vulnerability through patient-participant centeredness, and 5) ensuring the acceptance of next-of-kin/loved ones and community stakeholders.
Conclusion
EOL HIV cure-related research can be performed ethically and effectively by anticipating key issues that may arise. While not unique to the fields of EOL or HIV cure-related research, the considerations highlighted can help us support a new research approach. We must honor the lives of PLWHIV whose involvement in research can provide the knowledge needed to achieve the dream of making HIV infection curable

Performing rapid autopsy for the interrogation of HIV reservoirs.
: Rapid autopsy at the end of life in people with HIV (PWH) permits the preservation of valuable tissue specimens for subsequent study of HIV reservoirs. At our institution, we have developed a cohort of PWH who consent to a rapid autopsy to gather a wide range of fluids and tissues with the goal of advancing HIV cure research. The protocol for successfully performing these autopsies has required careful thought and development over months and years. We have now successfully performed six rapid autopsies and detail here our steps to build the study cohort, train and staff a team of more than a dozen personnel, and process and preserve hundreds of samples from each autopsy

Can research at the end of life be a useful tool to advance HIV cure?
Despite extensive investigations, we still do not fully understand the dynamics of the total body HIV reservoir and how sub-reservoirs in various compartments relate to one another. Studies using macaque models are enlightening but eradication strategies will still need to be tested in humans. To take the next steps in understanding and eradicating HIV reservoirs throughout the body, we propose to develop a âperi-mortem translational research modelâ of HIV-infected individuals (called âThe Last Giftâ), which is similar to existing models in cancer research. In this model, altruistic, motivated HIV-infected individuals with advanced non-AIDS related diseases and with six months or less to live will participate in HIV cure research and donate their full body after they die. Engaging this population provides a unique opportunity to compare the HIV reservoir before and after death across multiple anatomic compartments in relation to antiretroviral therapy use and other relevant clinical factors. Furthermore, people living with HIV/AIDS at the end of their lives may be willing to participate to cure interventions and accept greater risks for research participation. A broad, frank, and pragmatic discussion about performing HIV cure research near the end of life is necessary

"[It] is now my responsibility to fulfill that wish:" Clinical and rapid autopsy staff members' experiences and perceptions of HIV reservoir research at the end of life.
IntroductionLittle is known about the effects of HIV reservoir research at the end of life on staff members involved. Staff members' perceptions and experiences were assessed related to their involvement in the Last Gift, a rapid autopsy study at the University of California San Diego enrolling people living with HIV who are terminally ill and have a desire to contribute to HIV cure-related research.MethodsTwo focus group discussions consisting of clinical (n = 7) and rapid research autopsy (n = 8) staff members were conducted to understand the perspectives of staff members and the impact the Last Gift rapid autopsy study had on them. The total sample consisted of 66.7% females and 33.3% males and was ethnically diverse (66.7% Caucasian, 6.7% African American, 20.0% Asian descent, 6.7% Hispanic descent and American Indian) with a range of experience in the HIV field from 1 year to 30 years.ResultsQualitative focus group data revealed five major themes underlying study staff members' multilayered mental and practical involvement: 1) positive perceptions of the Last Gift study, with sub-themes including Last Gift study participants' altruism, fulfillment, and control at the end of life, 2) perceptions of staff members' close involvement in the Last Gift study, with sub-themes related to staff members' cognitive processing, self-actualization and fulfillment, stress management and resilience, coping mechanisms, and gratitude toward Last Gift participants and toward the study itself, 3) considerations for successful and sustainable study implementation, such as ethical awareness and sustained community and patient engagement, 4) collaborative learning and organizational processes and the value of interdependence between staff members, and 5) considerations for potential study scale-up at other clinical research sites.DiscussionUnderstanding staff members' nuanced emotional and procedural experiences is crucial to the Last Gift study's sustainability and will inform similar cure research studies conducted with people living with HIV at the end of life. The study's potential reproducibility depends on a robust research infrastructure with established, interdependent clinical and rapid autopsy teams, continuous community engagement, and an ethical and well-informed engagement process with people living with HIV

Lessons learned from the Last Gift study: ethical and practical challenges faced while conducting HIV cure-related research at the end of life.
The Last Gift is an observational HIV cure-related research study conducted with people with HIV at the end of life (EOL) at the University of California San Diego. Participants agree to voluntarily donate blood and other biospecimens while living and their bodies for a rapid research autopsy postmortem to better understand HIV reservoir dynamics throughout the entire body. The Last Gift study was initiated in 2017. Since then, 30 volunteers were enrolled who are either (1) terminally ill with a concomitant condition and have a prognosis of 6 months or less or (2) chronically ill with multiple comorbidities and nearing the EOL.Multiple ethical and logistical challenges have been revealed during this time; here, we share our lessons learnt and ethical analysis. Issues relevant to healthcare research include surrogate informed consent, personal and professional boundaries, challenges posed conducting research in a pandemic, and clinician burnout and emotional support. Issues more specific to EOL and postmortem research include dual roles of clinical care and research teams, communication between research personnel and clinical teams, legally required versus rapid research autopsy, identification of next of kin/loved ones and issues of inclusion. Issues specific to the Last Gift include logistics of body donation and rapid research autopsy, and disposition of the body as a study benefit.We recommend EOL research teams to have clear provisions around surrogate informed consent, rotate personnel to maintain boundaries, limit direct contact with staff associated with clinical care and have a clear plan for legally required versus research autopsies, among other recommendations
