Testing the Role of FDG-PET/CT to Predict Response to Therapy Prior to Surgery for HER2-positive Breast Cancer, The DIRECT Trial
NCT05710328
Recruiting
This phase II trial tests how well an imaging procedure called fludeoxyglucose F-18 (FDG) positron emission tomography/computed tomography (PET/CT) works in predicting response to standard of care chemotherapy prior to surgery in patients with HER2-positive stage IIa-IIIc breast cancer. FDG is a radioactive tracer that is given in a vein before PET/CT imaging and helps to identify areas of active cancer. PET and CT are imaging techniques that make detailed, computerized pictures of areas inside... Read More

Intravesical BCG vs GEMDOCE in NMIBC
NCT05538663
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
