847. A Qualitative Exploration of New and Existing HIV PrEP Modalities Among Men Who Have Sex with Men in Philadelphia

Abstract Background Daily oral pre-exposure prophylaxis (PrEP) is highly effective at preventing HIV when used as directed among men who have sex with men (MSM). However, challenges with uptake and adherence to daily oral PrEP have prompted the development of new modes of administration, including a long-acting, intramuscular injectable. We sought to explore the treatment characteristics that may influence the willingness and uptake of long-acting injectable PrEP as opposed to the daily pills among a racially diverse sample of MSM. Methods Between January and May 2021, we actively recruited 28 HIV-negative MSM (8 Black, 10 Latinx, 10 White) who lived in Philadelphia, PA during the past 12 months using social networking sites (e.g., Facebook and Instagram) and a community listserv. Qualitative data collection used a hybrid approach in which 4 focus groups and 10 semi-structured interviews were conducted virtually. Focus groups were kept racially and ethnically homogenous to identify differences in emerging themes related to PrEP willingness and preferences for specific prevention modalities. Results Participants discussed differing levels of interest and willingness to use long-acting injectable PrEP as opposed to the daily pills. The main perceived facilitator for injectable PrEP included convenience of use such as having fewer concerns with adhering to daily pills. Perceived barriers to injectable PrEP included (1) a dislike of needles as well as (2) concerns of potential side effects and (3) lower treatment efficacy (i.e., whether it will be as effective as the daily pills). While Black and Latinx MSM reported experiences of racism and discrimination within the healthcare system, they also reported greater willingness to consider intramuscular injectables if their healthcare providers would provide in-depth information about the risks and benefits of this new modality. Conclusion Our findings provide important guidance for the development and promotion of future strategies to enhance the uptake of long-acting injectable PrEP to address the HIV epidemic among MSM. Primary care providers should play a key role in ameliorating concerns related to hesitancy towards injectable PrEP, including emphasizing ease of dosing, effectiveness, and safety of long-acting PrEP to prevent infection.

Session: P-48. HIV: Pathogenesis
Background. The aims are to estimate the rates for, and examine the trends of, all-cause and cause-specific mortality since the beginning of the epidemic, in an effort to better forecast future mortality patterns and potentially prevent premature death.
Methods. All patients in the HIV Atlanta VA Cohort Study (HAVACS), an ongoing, open cohort of all HIV-infected veterans who ever sought or are seeking care at the Atlanta VA Medical Center, with a documented HIV diagnosis between January 1982 and December 2016 are included. All-cause and cause-specific mortality rates are calculated annually and for the study period, and age-adjusted to the 2000 U.S. standard population. Join-point regression analyses are performed to calculate annual percent changes (APC) and 95% CIs during periods of time when significant changes in trends are observed.

Background. Black and Hispanic/Latinx gay and other men who have sex with men (MSM), transgender women (TGW), transgender men (TGM), and gender nonbinary individuals (GNB) have been historically underrepresented in HIV prevention trials despite being disproportionately affected by the disease. Therefore, studies of pre-exposure prophylaxis (PrEP), a highly effective intervention for reducing HIV incidence, should include these individuals, and doing so would promote generalizability of the findings.

Approaches to Optimize Recruitment of Historically Underrepresented Black and Hispanic/LatinX MSM, Transgender, and Gender Non-binary Individuals into the Lenacapavir for PrEP (PURPOSE 2) Trial
Methods. PURPOSE 2 (GS-US-528-9023) will evaluate a twice-yearly long-acting subcutaneous, first in class capsid inhibitor, lenacapavir, for PrEP in MSM, TGW, TGM, and GNB in the US, Brazil, Peru, and South Africa. The study team adopted a multifactorial approach to address historic underrepresentation. This included a literature review to assess successful evidence-based approaches for increasing enrollment of Black and Hispanic/ LatinX MSM, TG, and GNB individuals. We engaged with community and patient advocates as well as key stakeholders to solicit feedback prior to protocol development.
Results. We established a trial-specific Global Community Advisory Group and implemented their recommendations for site selection, investigator and staff diversity, and strong linkage with community-based organizations. We recruited new community-based research sites and principal investigators (PIs) to mirror historically underrepresented populations and emphasized mentorship of junior sub-Is by seasoned PIs to support enrollment and retention. We developed required trainings for all study and site staff on good participatory practices for PrEP, anti-racism and transgender cultural humility. We established recruitment goals of 50% Black and 20% Hispanic/LatinX MSM in the US, and 20% TGW study-wide. Our strategy to ensure achievement of these overall goals involves nuanced site-specific recruitment goals considering site capacity, local demographics, and HIV incidence data. We will review metrics weekly during enrollment and make any necessary adjustments.
