A Phase III Study of Cabazitaxel With or Without Carboplatin in Patients With Metastatic Castrate-Resistant Prostate Cancer (mCRPC), Stratified by Aggressive Variant Signature
SWOG Cancer Research Network
Summary
This phase III trial compares the effect of adding carboplatin to the standard of care chemotherapy drug cabazitaxel versus cabazitaxel alone in treating prostate cancer that keeps growing even when the amount of testosterone in the body is reduced to very low levels (castrate-resistant) and that has spread from where it first started (primary site) to other places in the body (metastatic). Carboplatin is in a class of medications known as platinum-containing compounds. Carboplatin works by killing, stopping or slowing the growth of tumor cells. Chemotherapy drugs, such as cabazitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Prednisone is often given together with chemotherapy drugs. Prednisone is in a class of medications called corticosteroids. It is used to reduce inflammation and lower the body's immune response to help lessen the side effects of chemotherapy drugs and to help the chemotherapy work. Giving carboplatin with the standard of care chemotherapy drug cabazitaxel may be better at treating metastatic castrate-resistant prostate cancer.
Description
PRIMARY OBJECTIVES: I. To compare radiographic progression free survival (rPFS) between the two treatment arms in the subset of aggressive variant prostate cancer - molecular-pathologic signature (AVPC-MS)-positive participants. II. If the AVPC-MS positive test is statistically significant, test in AVPC-MS negative participants whether the combination of carboplatin and cabazitaxel improves rPFS. SECONDARY OBJECTIVES: I. To compare overall survival (OS) between the two treatment arms, stratified by AVPC-MS positive versus (vs.) negative. II. To compare response rates for prostate specific…
