    The primary objective of this study is to determine if an HIV-infected donor liver (HIVD+) transplant is safe with regards to major transplant-related and HIV-related complications. This study will evaluate if receiving a liver transplant from an HIV-infected deceased liver donor is safe with regards to survival and major transplant-related and HIV-related complications compared to receiving a liver from an HIV-uninfected deceased liver donor (HIVD-). Those participants who have accepted a HIVD- organ will be randomized to be followed in the full study or followed in the nested observational...

    We want to assess the baseline and cumulative seroprevalence of SARS-CoV-2 using serological and molecular assays. We will also administer a survey. Findings from this study will inform; 1) our understanding of changing epidemiology of COVID-19; 2) use of serological assays and testing algorithms, and 3) approaches to managing psychosocial stress in the community.

    Pfizer and Columbia University Irving Medical Center (CUIMC) are conducting a trial to learn about the safety and effectiveness of an experimental COVID-19 treatment, nirmatrelvir co-packaged with ritonavir, for children with COVID-19 that are at risk of the infection getting worse. Nirmatrelvir/ritonavir has been shown to be effective in fighting SARS-CoV-2 (the virus that causes COVID-19) in laboratory experiments and has been previously evaluated for safety in Phase 1 trials with healthy participants. The US FDA has granted Emergency Use Authorization (EUA) to nirmatrelvir/ritonavir for...

    We are seeking volunteers who have been diagnosed with COVID-19 by a healthcare provider or by lab testing. We are also looking for volunteers who have never tested positive for COVID-19 and have not received a COVID-19 vaccine. The study, also known as C-PIC, will be looking at antibody levels and how long the virus remains in the body. We are also studying the long-term complications that can occur after recovery from an acute COVID-19 infection, commonly referred to as long-COVID, long-haul COVID, and post-acute sequelae of SARS-CoV-2 (PASC). At each visit, you will be asked to complete a...

    Scientists are looking for ways to effectively clear HIV that rests in areas of the body where standard antiretroviral treatment (ART) is unable to reach. IL-15 superagonist (N-803) appears to reactivate HIV that is asleep and is also thought to increase the body's natural immune response to HIV. Broadly neutralizing antibodies (bNAbs), such as 10-1074 and VRC07-523LS, have been shown to control growth of HIV in the blood and to increase the body's immune response to HIV. N-803 alone or in combination with bNAbs may provide greater control of HIV than previous efforts. The purpose of this...

    We are looking for individuals 18 to 60 years old who are interested in learning more about HIV prevention and biomedical research studies. We will ask you to complete a brief questionnaire to find out if we can schedule you for a one-on-one, 1.5-hour education visit to learn about the research we do. The education visit will help you decide if you want to participate in one of our studies. You will be compensated for the visit. Your responses to this questionnaire will be kept strictly confidential.

    The HIV Vaccine Trials Network (HVTN) and Columbia University Irving Medical Center (CUIMC) are conducting a study to learn about the safety and effectiveness of an experimental HIV vaccine. The study vaccine is a protein vaccine called N332-GT5 gp140. It includes a manmade protein that looks like a protein found on the outside of HIV. The study vaccine is given with an adjuvant called SMNP. Adjuvants are products that help alert the immune system to have a stronger response. Researchers hope that the immune system will respond by making antibodies and T-cells that could recognize and fight...
