HIV Vaccine and Monoclonal Antibody Studies
In collaboration with the NIH/NIAID-funded HIV Vaccine Trials Network (HVTN) and with the Columbia Partnership for Prevention and Control of HIV/AIDS Clinical Trials Unit, this work involves implementation of multiple Phase 1-3 HIV vaccine research trials to test the safety, tolerability, and efficacy of HIV vaccine products and monoclonal antibodies to prevent HIV infection through our research site, Project ACHIEVE.
HIV Injectable Pre-Exposure Prophylaxis Study
In collaboration with the NIH/NIAID-funded HIV Prevention Trials Network (HPTN), this multi-site, multi-country study is a Phase 2/3 study comparing injectable cabotegravir to emtricitabine/tenofovir (FTC/TDF) for preventing HIV infection in men who have sex with men and transgender women.
Neighborhoods, Networks, and the HIV Care Continuum
This NIH/NIMH-funded two-phase research study involves a mixed methods approach to ascertain unique, salient neighborhood and network factors that influence HIV care continuum outcomes (retention in care, ART adherence, and viral suppression) among HIV-infected men who have sex with men in New York City using qualitative interviews and spatial analysis and multilevel modeling.
Pre-Exposure Prophylaxis in Women
This NIH R340-funded three-phase project seeks to develop and pilot an intervention to enhance uptake of pre-exposure prophylaxis (PrEP) among women at risk for HIV, and support adherence, and linkage to care in New York City and Philadelphia. Text based messaging will be used to encourage PrEP adherence, and the feasibility and acceptability of the intervention will be tested.
Hepatitis C Infections among Men Who Have Sex with Men
This research aims to determine the prevalence of recent and chronic hepatitis C (HCV) infections among MSM in NYC, map HCV infections by home, social, and sexual neighborhoods, and determine clusters of genetically linked HCV variants among recently and chronically HCV-infected MSM in NYC using phylogenetic analysis.
Blood Donation in Men Who Have Sex with Men
A pilot study seeks to identify and describe motivations, barriers, and facilitators to blood donation among Black donors by analyzing YouTube video content. In addition, as a collaboration between the New York Blood Center, One Blood, and Blood Systems at UCSF, an NIH grant proposal has been submitted to evaluate the impact of the change to a 1-year deferral from blood donation for men who have sex with men in five diverse regions of the US. The project is a mixed-methods study in three parts: 1) an online survey of accepted male donors; 2) a qualitative evaluation with MSM donors and blood center staff; and 3) the development of a behavioral inventory to identify questions that distinguish high- from low-risk men who have sex with men.
