Intravesical BCG vs GEMDOCE in NMIBC
Recruiting
The study hypothesis is that BCG naïve non-muscle invasive bladder cancer (NMIBC) patients treated with intravesical Gemcitabine + Docetaxel (GEMDOCE) will result in a non-inferior event-free survival (EFS) compared to standard treatment with intravesical BCG. The purpose of this study is to test whether Gemcitabine + Docetaxel is a better or worse treatment than the usual BCG therapy approach. The primary objective of this study is to determine the event free survival (EFS) of BCG-naïve high gr... Read More

National Cancer Institute "Cancer Moonshot Biobank"
Recruiting
This trial collects multiple tissue and blood samples, along with medical information, from cancer patients. The "Cancer Moonshot Biobank" is a longitudinal study. This means it collects and stores samples and information over time, throughout the course of a patient's cancer treatment. By looking at samples and information collected from the same people over time, researchers hope to better understand how cancer changes over time and over the course of medical treatments.
