Two Studies for Patients With Unfavorable Intermediate 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 Higher Gene Risk Score, The Guidance Trial
NCT05050084
Recruiting
This phase III trial uses the Decipher risk score to guide therapy selection. Decipher score is based on the activity of 22 genes in prostate tumor and may predict how likely it is for recurrent prostate cancer to spread (metastasize) to other parts of the body. Decipher score in this study is used for patient selection and the two variations of treatment to be studied: intensification for higher Decipher score or de-intensification for low Decipher score. Patients with higher Decipher risk scor... Read More

Testing the Addition of the Drug Apalutamide to the Usual Hormone Therapy and Radiation Therapy After Surgery for Prostate Cancer, INNOVATE Trial
NCT04134260
Recruiting
This phase III trial studies whether adding apalutamide to the usual treatment improves outcome in patients with lymph node positive prostate cancer after surgery. Radiation therapy uses high energy x-ray to kill tumor cells and shrink tumors. Androgens, or male sex hormones, can cause the growth of prostate cancer cells. Drugs, such as apalutamide, may help stop or reduce the growth of prostate cancer cell growth by blocking the attachment of androgen to its receptors on cancer cells, a mechani... Read More

A Study of Treatment for Medulloblastoma Using Sodium Thiosulfate to Reduce Hearing Loss
NCT05382338
Recruiting
This phase III trial tests two hypotheses in patients with low-risk and average-risk medulloblastoma. Medulloblastoma is a type of cancer that occurs in the back of the brain. The term, risk, refers to the chance of the cancer coming back after treatment. Subjects with low-risk medulloblastoma typically have a lower chance of the cancer coming back than subjects with average-risk medulloblastoma. Although treatment for newly diagnosed average-risk and low-risk medulloblastoma is generally effect... Read More
