SWOG Study S1314 Page

This page is for reference and assistance to study sites participating in SWOG's clinical trial S1314, "A Randomized Phase II Study of CO-eXpression ExtrapolatioN (COXEN)-directed Neoadjuvant Chemotherapy for Localized, Muscle-Invasive Bladder Cancer."

Why is this study being done?

The primary focus of this study is to see if looking at tumor biomarkers using a program called "coexpression extrapolation or COXEN" may predict a patient's response to chemotherapy before surgery. The COXEN program will not select the therapy, but the type of chemotherapy that the patients receive will be randomly decided. Information will be gathered and afer completion of the study, researchers will look at this information and outcomes for all study participants to see how COXEN relates to how participants responded to chemotherapy. Other potential tests to predict a patient's response to chemotherapy will also be evaluated.

In this study, patients will receive the treatment in Arm 1 (gemcitabine and cisplatin) or the treatment in Arm 2 [methotrexate, vinblastine, doxorubicin, cisplatin, and filgrastim (or pegfilgrastim)]. There will be about 184 people taking part in this study (92 in each arm).
