Translational Science Benefits
The Pre-Exposure Prophylaxis for HIV (PrEP) Among African American Men Who Have Sex With Men (MSM) study investigated the usage of PrEP among young high-risk men. Rupa Patel, MD, MPH, DTM&H, was awarded ICTS pilot funding in 2015 to conduct a quantitative and qualitative study of PrEP uptake by high-risks persons.
Human immunodeficiency virus (HIV) prevention now includes using HIV medications for pre-exposure prophylactics (PrEP) to prevent infection before the exposure happens in high-risk populations. African American (AA) men, ages 13-35 years, who have sex with men (MSM) have the highest rates of new HIV infections. When taken consistently, PrEP has been shown to reduce the risk of HIV infection in people who are at high risk by up to 92%.1 Little is known about PrEP use by high-risk persons.
The goal of the study was to learn more about PrEP uptake and the reasons for PrEP uptake among young African American high-risk men who were offered PrEP at four different clinics in St. Louis.
Overall, the PrEP study led to expansion of the Washington University School of Medicine in St. Louis HIV Program for additional studies on PrEP uptake, adherence, and utilization leading to opportunities for patients. The PrEP clinic has also served as a model for other clinics in the local St. Louis area, other states, and international settings.
A PrEP service delivery care program was established as a clinic and now serves as a site for PrEP adherence testing using urine and blood biomarkers for pre-exposure prophylaxis. The clinic is also a site for the HIV Prevention Trials Network (HPTN) HPTN 083 Study, a Phase 2b /3 trial.
Demonstrated benefits are those that have been observed and are verifiable.
Potential benefits are those logically expected with moderate to high confidence.
New diagnostic procedures using urine biomarkers for monitoring of pre-exposure prophylaxis identified. demonstrated.
Missouri Pre-Exposure Prophylaxis (PrEP) Implementation Toolkit provides guidance for providers and administrators for PrEP use. demonstrated.
Missouri Pre-Exposure Prophylaxis (PrEP) provides guidance for consumers and providers. Available in English and Spanish. demonstrated.
Rupa Patel helped review the World Health Organization (WHO) Implementation Tool for Pre-Exposure Prophylaxis of HIV Infection. demonstrated.
Pre-Exposure Prophylaxis (PrEP) contains guidance for consumers and providers. Missouri Department of Health and Senior Services. Available in English and Spanish. demonstrated.
PrEP has the ability to halt transmission of the virus among certain populations and sexual networks. demonstrated.
Lack of insurance coverage was identified as a barrier to PrEP utilization. Quantifying how insurance coverage affects PrEP allows for modeling of cost savings and HIV incidence reduction. demonstrated.
The Washington University PrEP Clinic is a site for the HIV Prevention Trials Network (HPTN) HPTN 083 Study, a Phase 2b/3 trial. HPTN 083 is evaluating the efficacy of the long-acting injectable agent, cabotegravir (CAB LA), for pre-exposure prophylaxis in HIV-uninfected men and transgender women who have sex with men (MSM and TGW). demonstrated.
The PrEP clinic site has been used to advise other clinics in the local St. Louis area, state-level Missouri area, and also in African international settings. demonstrated.
Established a simplified renal monitoring baseline to allow for same-day PrEP prescribing and reducing the need for testing procedures, staffing, and cost burden during PrEP implementation. demonstrated.
Developed and tested PrEP@Home, a home care system that includes all components of a PrEP follow-up visit and is designed to reduce annual in-person PrEP clinician visits from 4 per year to 1 per year. demonstrated.
Developed a pharmacy-based model for delivery of PrEP based on collaboration with Gateway Apothecary, a community pharmacy. Gateway Apothecary conducts HIV testing, kidney monitoring, PrEP adherence, and risk reduction counseling. demonstrated.
Dr. Patel is a member of the World Health Organization (WHO) Technical Advisory Group (TAG) for PrEP. demonstrated.
Dr. Patel is an advisor for PrEP Clinical Services to JHPIEGO, BRIDGE to SCALE grant (Gates Foundation). demonstrated.
Dr. Patel served as an expert witness for a criminal trial case. demonstrated.
Benefits of the PrEP study have been observed in three TSBM domains since 2015. The PrEP study led to development of guidelines and a mobile application2 for health care providers,3,4 administrators and consumers,5 and identification of strategies for successful implementation of PrEP uptake and prevention of disease as well as barriers to PrEP usage. New investigative and diagnostic procedures using urine biomarkers for pre-exposure prophylaxis have been identified.6 Tools for adherence-pharmacy measures using urine and blood biomarkers to determine the level of protection a patient has from acquiring HIV are in process. PrEP@Home, a home care system that includes all components of a PrEP follow-up visit was developed and tested.7 The study also established a simplified renal monitoring baseline to allow for same-day PrEP prescribing, and reducing the need for testing procedures, staffing and cost burden during PrEP implementation.8 The PrEP clinic is now a site for the HIV Prevention Trials Network (HPTN) HPTN 083 Study, a Phase 2b /3 trial. HPTN 083 is evaluating the efficacy of the long-acting injectable agent, cabotegravir (CAB LA), for pre-exposure prophylaxis in HIV-uninfected men and transgender women who have sex with men (MSM and TGW).
