Testing the Addition of Radiation Therapy to the Usual Immune Therapy Treatment (Atezolizumab) for Extensive Stage Small Cell Lung Cancer, The RAPTOR Trial
Recruiting
This phase II/III trial compares the effect of adding radiation therapy to the usual maintenance therapy with atezolizumab versus atezolizumab alone in patients who have already received atezolizumab plus chemotherapy for the treatment of small cell lung cancer that has spread outside of the lung or to other parts of the body (extensive stage). Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability o... Read More

Testing the Addition of a New Anti-cancer Drug, Radium-223 Dichloride, to the Usual Treatment (Cabozantinib) for Advanced Renal Cell Cancer That Has Spread to the Bone, RadiCaL Study
Recruiting
This phase II trial studies whether adding radium-223 dichloride to the usual treatment, cabozantinib, improves outcomes in patients with renal cell cancer that has spread to the bone. Radioactive drugs such as radium-223 dichloride may directly target radiation to cancer cells and minimize harm to normal cells. Cabozantinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving radium-223 dichloride and cabozantinib may help lessen the pain and sympto... Read More

This phase II/III trial studies how well radiation therapy works when given together with cisplatin, docetaxel, cetuximab, and/or atezolizumab after surgery in treating patients with high-risk stage III-IV head and neck cancer the begins in the thin, flat cells (squamous cell). Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Drugs used in chemotherapy, such as cisplatin and docetaxel, wor... Read More
