This clinical trial is focused on studying a type of cancer called urothelial carcinoma, which affects the lining of the urinary system, including the bladder. The study is testing a treatment using a medication called clofarabine, which is given as an infusion directly into the bloodstream. The purpose of the study is to find the highest dose of clofarabine that patients can tolerate without severe side effects.
Participants in the study will receive clofarabine in increasing doses to determine the safest and most effective amount. The study will monitor how the cancer responds to the treatment and how long any positive effects last. Researchers will also observe how the cancer progresses over time and the overall survival of participants. Additionally, the study will track any side effects related to the treatment.
The trial will also gather information on how clofarabine behaves in the body, such as how much of the drug is present in the blood at different times. This information will help in understanding the best way to use clofarabine for treating urothelial carcinoma in the future.
