Observation or Radiation Therapy in Treating Patients With Newly Diagnosed Grade II Meningioma That Has Been Completely Removed by Surgery
Recruiting
This randomized phase III trial studies how well radiation therapy works compared with observation in treating patients with newly diagnosed grade II meningioma that has been completely removed by surgery. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors.

Two Studies for Patients With High Risk Prostate Cancer Testing Less Intense Treatment for Patients With a Low Gene Risk Score and Testing a More Intense Treatment for Patients With a High Gene Risk Score, The PREDICT-RT Trial
Recruiting
This phase III trial compares less intense hormone therapy and radiation therapy to usual hormone therapy and radiation therapy in treating patients with high risk prostate cancer and low gene risk score. This trial also compares more intense hormone therapy and radiation therapy to usual hormone therapy and radiation therapy in patients with high risk prostate cancer and high gene risk score. Apalutamide may help fight prostate cancer by blocking the use of androgen by the tumor cells. Radiatio... Read More

Comparing the Addition of Radiation Either Before or After Surgery for Patients With Brain Metastases
Recruiting
This phase III trial compares the usual treatment of surgery after stereotactic radiosurgery (SRS) to receiving SRS before surgery in treating patients with cancer that has spread to the brain (brain metastases). Stereotactic radiosurgery is a type of radiation therapy that delivers a high dose of radiation to target tumors and minimizes effect on normal surrounding brain tissue. The combination of surgery and radiation may stop the tumor from growing for a few months or longer and may reduce sy... Read More

Testing Shorter Duration Radiation Therapy Versus the Usual Radiation Therapy in Patients With High Risk Prostate Cancer
Recruiting
This phase III trial compares stereotactic body radiation therapy (SBRT), (five treatments over two weeks using a higher dose per treatment) to usual radiation therapy (20 to 45 treatments over 4 to 9 weeks) for the treatment of high-risk prostate cancer. SBRT uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period of time. This trial is evaluating if shorter duration radiation preve... 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

A Study to Investigate the Safety, Tolerability, Pharmacokinetics (PK) and Pharmacodynamics (PD) of RO7497372 in Participants With Diabetic Macular Edema (DME)
Recruiting
This study will assess the safety and tolerability of RO7497372 in participants with DME. The study consists of 2 parts. Part 1 will test multiple-ascending doses of RO7497372 after unilateral intravitreal (IVT) administration in participants with DME. The main purpose of Part 1 is to provide data for RO7497372 safety and tolerability, as well as to characterize the ocular and systemic pharmacokinetics (PK), systemic anti-drug antibodies (ADA), and duration of target engagement, i.e., the pharma...

Testing the Addition of MEDI4736 (Durvalumab) to Chemotherapy Before Surgery for Patients With High-Grade Upper Urinary Tract Cancer
Recruiting
This phase II/III trial compares the effect of adding durvalumab to chemotherapy versus chemotherapy alone before surgery in treating patients with upper urinary tract cancer. Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as methotrexate, vinblastine, doxorubicin, cisplatin, and gemcitabine work in different ways to stop the growth of... Read More

A Study Investigating Subcutaneously Administered Pozelimab in Combination With Cemdisiran or Cemdisiran Alone in Adult Participants With Geographic Atrophy
Recruiting
This study is researching experimental (study) drugs called pozelimab and cemdisiran. The study is focused on participants who have geographic atrophy (GA) caused by age-related macular degeneration (AMD). Geographic atrophy is a medical term that refers to later-stage cases of AMD which is an eye condition affecting central vision (what one sees straight ahead). The purpose of this study is to evaluate the progression rate of Geographic Atrophy in eyes of patients treated with cemdisiran alone... Read More

Phase I investigated the safety of RO7446603 following a single and multiple intravitreal (IVT) doses as monotherapy or co-administered with IVT aflibercept or IVT faricimab (in separate injections). Phase II will investigate the safety, tolerability, pharmacokinetics (PK)... Read More
