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

A Trial to Learn if Fianlimab and Cemiplimab Are Safe and Work Better Than Anti-PD1 Alone in Adult Participants With Resectable Stage 3 or 4 Melanoma
Recruiting
This study is researching an experimental drug called REGN3767, also known as fianlimab (R3767), when combined with another medication called cemiplimab (each individually called a "study drug" or called "study drugs" when combined) compared with cemiplimab alone. These types of immunotherapy study drugs are collectively known as immune checkpoint inhibitors. Immunotherapies are treatments that use the immune system to recognize and kill cancer cells. The study is focused on participants with a... Read More

Testing the Feasibility and Acceptability of Social Media and Digital Therapeutics to Decrease Vaping Behaviors
Recruiting
Use of vaping products (e.g., electronic nicotine delivery systems, e-cigarettes) has been increasing rapidly, particularly among teens and young adults. With limited information on the long-term effects of vaping products, health information about vaping has been somewhat unclear in regards to associated health risks. Teens and young adults may be reluctant to disclose their use of vaping products to parents or health providers and instead turn to social media to share and seek out information... 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

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
