We are conducting a research study to see if hormone therapy (HT) helps reduce hot flashes and night sweats in women living with HIV in the late menopausal transition (similar to what is known as perimenopause) or early post-menopause (the time after the final menstrual period or after removal of both ovaries). If you were assigned female sex at birth, are…
The purpose of this study is to assess the safety of the Investigational study drug called BNT351 and get information about how well it works for HIV. BNT351 is currently being tested in humans and is the first time the study drug will be given to people. It is not FDA approved yet. You will be invited to take part if you are 18 to 65 years of age in good…
Have you been diagnosed with diabetes or prediabetes? Do you own a smartphone? A team of researchers at Columbia University is researching a smartphone application called T2 Coach to help individuals living with diabetes set personalized nutrition and physical activity goals. You may be eligible to participate in a 3-week-long study using the T2 Coach…
HPTN 115/Foxxy Doxy is looking at doxycycline, a well-known antibiotic that is commonly used to prevent and treat acne and some sexually transmitted infections (STIs) like gonorrhea, chlamydia, and syphilis. This study is trying to find out if taking doxycycline either after condomless sex (known as on-demand doxyPEP) or weekly doxycycline can reduce STI…
Seeking participants for a study about how individuals prefer to receive nutrition recommendations to support health management and preferences for visualizing health data. Participants may be invited to complete a 60-minute session to answer questionnaires and evaluate different styles of nutritional recommendations. In addition, they may be invited to…
A future without Type 1 Diabetes (T1D) starts with you. Get screened! Thanks in large part to T1D family members, we understand T1D as a disease that progresses in three distinct stages. This new definition in conjunction with TrialNet's Pathway to Prevention screening, allows for earlier detection and intervention.
The overall goal of this project is to determine whether the timing of your meals and sleep influences health. We are looking for adults aged 30 and older with type 2 diabetes to participate in a sleep study. Participants must be willing to keep a written food and sleep record for 7 consecutive days. Participants who complete this study will receive a total…
Clostridioides difficile (C. difficile) is a bacterium (germ) that can spread from one person to another causing severe diarrhea (watery poop) that at its worst can lead to death. Pfizer has been studying an investigational vaccine to prevent diarrhea caused by C. difficile. To be part of this study you must be 65 years old or older and have one or more of…
Are you suffering from persistent symptoms that began after you were diagnosed and treated with antibiotics for Lyme Disease? This new research study aims to test a new form of treatment for people with persistent symptoms despite antibiotic treatment for Lyme disease. This treatment involves stimulating a nerve on the surface of your ear. This is called…
We are conducting a research study on the effect of high insulin levels on the buildup of excessive liver fat ("fatty liver disease") in people at risk for type 2 diabetes. We are seeking adult volunteers, ages 18-65, who have obesity with a body mass index of 30-45, and have been diagnosed with, or are at risk for, prediabetes and metabolic…
Thank you for your interest in our research! We are studying how life experiences impact brain health and memory in people with and without HIV. Your participation can help advance science and improve future care. What's involved? You'll come to the Columbia University Irving Medical Center for a one-time visit, which includes a blood draw, urine…
Have you been treated for Lyme Disease but continue to have brain fog or other cognitive problems? This research study will assess a non-medication non-invasive intervention to improve cognitive functioning in people with persistent cognitive problems despite prior antibiotic treatment for Lyme Disease. Participants will complete this 4 week intervention at…
This patient case registry for Lyme and other Tick-borne Diseases is a component of the Clinical Trials Network that was launched in 2021 by a grant from the Steven and Alexandra Cohen Foundation. The registry will gather general information such as demographics, medical history, and current functional status. This information will help researchers to…
In PRECIDENTD, we hope to learn which diabetes medications work best to reduce the risk of heart and kidney disease in people with type 2 diabetes. People with type 2 diabetes are twice as likely to have heart disease or a stroke compared to someone who does not have diabetes, and they are likely to have heart disease or stroke at a younger age. People with…
The primary objective is to determine whether using hearts from HIV+ donors for HIV+ recipients is safe with regard to major transplant-related and HIV-related complications. The primary outcome is patient survival at one year. If you have any questions regarding this study, please contact the Transplant Clinical Research Center (TCRC).
We are recruiting volunteers, aged 18-70, for a research study on the buildup of excessive liver fat ("fatty liver disease") in people with or at risk for type 2 diabetes because their bodies are resistant to the actions of the blood sugar-lowering hormone, insulin. To do this, we seek to temporarily induce or accentuate insulin resistance in 14…
Do you identify as a woman or transgender person, or do you have a non-binary gender identity? Has a medical provider ever diagnosed you with a sexually transmitted infection or recommended PrEP/another HIV prevention method? We are conducting a study to understand attitudes and preferences regarding HIV prevention methods among people who do not have HIV.…
We are looking for individuals 18 to 65 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…
