Testing the Addition of the Drug Relugolix to the Usual Radiation Therapy for Advanced-Stage Prostate Cancer, The NRG Promethean Study
Recruiting
This phase II trial compares the usual treatment of radiation therapy alone to using the study drug, relugolix, plus the usual radiation therapy in patients with castration-sensitive prostate cancer that has spread to limited other parts of the body (oligometastatic). Relugolix is in a class of medications called gonadotropin-releasing hormone (GnRH) receptor antagonists. It works by decreasing the amount of testosterone (a male hormone) produced by the body. It may stop the growth of cancer cel... Read More

Testing the Addition of the Chemotherapy Drug Lomustine (Gleostine) to the Usual Treatment (Temozolomide and Radiation Therapy) for Newly Diagnosed MGMT Methylated Glioblastoma
Recruiting
This phase III trial compares the effect of adding lomustine to standard chemotherapy with temozolomide and radiation therapy versus temozolomide and radiation therapy alone in shrinking or stabilizing newly diagnosed MGMT methylated glioblastoma. MGMT methylated tumors are more likely to respond to temozolomide chemotherapy. Temozolomide is in a class of medications called alkylating agents. It works by damaging the cell's DNA and may kill tumor cells and slow down or stop tumor growth. Lomusti... Read More

Testing Longer Duration Radiation Therapy Versus the Usual Radiation Therapy in Patients With Cancer That Has Spread to the Brain
Recruiting
This phase III trial compares the effectiveness of fractionated stereotactic radiosurgery (FSRS) to usual care stereotactic radiosurgery (SRS) in treating patients with cancer that has spread from where it first started to the brain. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. FSRS delivers a high dose of radiation to the tumor over 3 treatments. SRS is a type of external radiation therapy that uses special equipment to position the patient and precisely give... Read More

Testing the Addition of High Dose, Targeted Radiation to the Usual Treatment for Locally-Advanced Inoperable Non-small Cell Lung Cancer
Recruiting
This phase III trial compares the effect of adding stereotactic body radiation therapy (SBRT) to the usual treatment (conventional image guided radiation therapy \[IGRT\] and chemotherapy followed by immunotherapy with durvalumab or osimertinib) versus the usual treatment alone in treating patients with non-small cell lung cancer that has spread to nearby tissue or lymph nodes (locally advanced) and cannot be treated by surgery (inoperable). SBRT uses special equipment to position a patient and... Read More

Active Surveillance, Bleomycin, Etoposide, Carboplatin or Cisplatin in Treating Pediatric and Adult Patients With Germ Cell Tumors
Recruiting
This phase III trial studies how well active surveillance help doctors to monitor subjects with low risk germ cell tumors for recurrence after their tumor is removed. When the germ cell tumor has spread outside of the organ in which it developed, it is considered metastatic. Chemotherapy drugs, such as bleomycin, carboplatin, etoposide, and cisplatin, 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 sp...

A Study to Learn About the Study Medicine Elranatamab Alone and With Daratumumab in People With Multiple Myeloma Who Have Received Other Treatments
Recruiting
The purpose of this clinical trial is to (1) learn whether the BCMA-CD3 bispecific antibody elranatamab can provide more benefit to people with multiple myeloma compared to a combination therapy including daratumumab, pomalidomide, and dexamethasone, and (2) learn about the safety and activity of elranatamab in combination with the anti-CD38 monoclonal antibody daratumumab. People with multiple myeloma who have received previous treatment including lenalidomide will be enrolled in the study. Pa... Read More
