Kimball Research Institute Contact Information Email: HTieu@nybc.org Phone: +1 (212) 570-3081 Current Projects Established in 1993 and previously led by Dr. Beryl Koblin, the Laboratory of Infectious Disease Prevention is a leader in HIV and infectious disease epidemiology and prevention research. We are part of the largest clinical trials program devoted to the development and testing of preventive HIV vaccines worldwide (NIH/NIAID-funded HIV Vaccine Trials Network, www.hvtn.org). As part of the global response to the COVID-19 pandemic caused by SARS-CoV-2 virus, we are also part of the clinical trials program devoted to the development and testing of SARS-CoV-2 vaccines and monoclonal antibodies to prevent COVID-19 (NIH/NIAID-funded COVID-19 Prevention Network, www.coronaviruspreventionnetwork.org). We use epidemiology to stay up to date on who is at risk for HIV and other infectious diseases and why. We design and test innovative prevention strategies to increase HIV testing and pre-exposure prophylaxis (PrEP) uptake and reduce risk. We conduct our epidemiology and clinical studies and community engagement through our research site, Project ACHIEVE (www.projectachieve.org). Our research collaborators include the Columbia Research Unit. Together, we form the NIH-funded by Columbia Collaborative HIV/AIDS Clinical Trials Unit. SARS-CoV-2 Vaccine Studies In collaboration with the COVID-19 Prevention Network (CoVPN), our research involves implementation of multiple Phase 3 SARS-CoV-2 clinical research trials to test the safety, tolerability, and efficacy of vaccine products to prevent COVID-19, as well as a study testing whether vaccination with the Moderna mRNA vaccine reduces infection and spread of SARS-CoV-2 virus to close contacts. HIV Vaccine and Monoclonal Antibody Studies In collaboration with the HIV Vaccine Trials Network (HVTN) and Columbia Collaborative HIV/AIDS Clinical Trials Unit, our research involves implementation of multiple Phase 1-3 clinical research trials to test the safety, tolerability, and efficacy of HIV vaccine products and monoclonal antibodies to prevent HIV infection. HIV Injectable Pre-Exposure Prophylaxis Study In collaboration with the HIV Prevention Trials Network (HPTN), this multi-site, multi-country HPTN 083 study is a Phase 2b/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 three-phase research study involves a mixed methods approach to ascertain neighborhood and network factors that influence HIV care continuum outcomes (retention in care, antiretroviral therapy adherence, and viral suppression) among men who have sex with men living with HIV in New York City using qualitative interviews and spatial analysis and multilevel modeling. This is followed by a longitudinal study among 550 MSM living with HIV over two years to evaluate the influence of neighborhoods and networks on HIV care continuum over time. Pre-Exposure Prophylaxis in Women This NIH/NIMH-funded R34-funded three-phase project seeks to develop and pilot an intervention to enhance uptake of pre-exposure prophylaxis (PrEP) among cisgender women at risk for HIV, and support adherence, and linkage to care in New York City and Philadelphia. Hepatitis B and C Infections among Men Who Have Sex with Men This Gilead investigator-initiated funded research aims to determine the prevalence of recent and chronic hepatitis C and B infections among MSM in the US enrolled in the HVTN 505 study. Barriers and Facilitators to Blood Donation This pilot study seeks to identify and describe motivations, barriers, and facilitators to blood donation among donors by analyzing YouTube video content and qualitative data analysis.
