Principal Investigator:
Marcus Rebello Pereira, MDThe 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... -

Principal Investigator:
Magdalena E Sobieszczyk, MDWe 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. -

Magdalena E Sobieszczyk, MDPfizer 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... -
Principal Investigator:
Michael T Yin, MDWe 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... -
Principal Investigator:
Magdalena E Sobieszczyk, MDThe main purpose of this study is to evaluate the ability of an experimental oral drug called S-217622 to improve the health of people with coronavirus disease 2019 (COVID-19). We also want to see if this study drug is safe, and if this study drug can shorten the time you have COVID-19 symptoms, reduce the amount of virus in the body, and prevent hospitalization or death. You will be eligible for this study if you are considered at lower risk for severe COVID-19 and have none of the risk factors that would put you at higher risk of disease progression. Study drug will be either an active... -
Principal Investigator:
Magdalena E Sobieszczyk, MDWe are looking for HIV-negative individuals 18 to 60 years old who are interested in learning more about HIV prevention 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. -

Principal Investigator:
Marcus Rebello Pereira, MDIn this research study, we want to find out how well patients that receive a kidney from an HIV-positive (HIV+) donor do over 10 years compared to patients who receive a kidney from an HIV-negative (HIV-) donor. This research study is for adults who are HIV+ and are being evaluated for or are waitlisted to receive a kidney transplant. It is also available for adults who are HIV+ and previously received a kidney-only transplant under a HOPE Act protocol. To take part in this study you must be willing to accept a kidney from an HIV+ or HIV- donor. If you decide not to join this study, you will... -
Principal Investigator:
Jason E Zucker, MDSome things about the recent mpox outbreak were different from past, smaller mpox outbreaks. That means not enough is known about how certain health issues related to mpox might continue to affect some patients months later. To understand this, researchers also need to compare some feelings, well-being, and behaviors of persons who had mpox with those of persons who did not have mpox. This research study can provide important new information. It might also help better reduce some of those problems in the future, and help reduce future mpox outbreaks. Study participation entails a one-time...
