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

Naxitamab Added to Induction for Newly Diagnosed High-Risk Neuroblastoma
Recruiting
This is a prospective, multicenter clinical trial in subjects with newly diagnosed high-risk neuroblastoma to evaluate the efficacy and safety of administering naxitamab with standard induction therapy. The initial chemotherapy will include 5 cycles of multi-agent chemotherapy. Naxitamab will be added to all 5 Induction cycles. We hypothesize that the addition of anti-GD2 therapy to induction chemotherapy will result in improved end of induction responses and improved survival.
