This study is being done to answer the following question: Can we lower the chance of your bladder cancer growing or spreading by using one type of chemotherapy instilled in the bladder, Gemcitabine and Docetaxel, instead of the usual therapy? The usual approach for patients who are not in a study is treatment with Transurethral surgery of bladder tumor (…
Kidney transplant extends life, improves quality of life, and reduces healthcare costs. Unfortunately, there are not enough donated kidneys, so many people who need a transplant spend years on the waiting list. Kidneys from organ donors who have hepatitis C virus (HCV) are often thrown away, but these kidneys work well, and hepatitis C can be cured. The…
The purpose of this study is to determine if an investigational drug called tegoprubart (also known as AT1501) is safe and effective in preventing rejection in patients who are undergoing a kidney transplant for the first time. Participants will be randomly assigned to tegoprubart or standard treatment with tacrolimusat the time of transplant. If you have…
This study is for patients who have bladder cancer that has not invaded muscle tissue and who have been treated with one or more surgical resections and Bacillus Calmette-Guerin or BCG, which was directly given into the bladder before. The main purpose of this trial is to show that durvalumab is safe when given alone, in combination with BCG treatments, and…
We're conducting a research study on how much insulin is needed to control blood sugar in people who are made temporarily resistant to insulin's effects. Insulin is the main hormone (chemical signal) that the body uses to lower the levels of sugar in the blood. We are interested in looking at insulin levels because we think that lowering insulin…
