Lenalidomide, and Dexamethasone With or Without Daratumumab in Treating Patients With High-Risk Smoldering Myeloma
Recruiting
This phase III trial studies how well lenalidomide and dexamethasone works with or without daratumumab in treating patients with high-risk smoldering myeloma. Drugs used in chemotherapy, such as lenalidomide and dexamethasone, 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. Immunotherapy with monoclonal antibodies, such as daratumumab, may induce changes in the body's immune system and may... Read More

A Study to Test Radium-223 With Docetaxel in Patients With Prostate Cancer
Recruiting
The purpose of this study is to compare any good and bad effects of using radium-223 along with docetaxel chemotherapy treatment versus using docetaxel alone. Earlier studies helped show that the combination is safe, but the combination has not been proven to work better than either drug alone. The goal of this study is to find out if combining docetaxel and radium-223 is better than giving either drug by itself.
