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
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

Genome Transplant Dynamics
Recruiting
Study Description:
Heart and lung transplants can save lives, but long-term success is often limited by organ rejection that is hard to detect early. This study is testing a new, non-invasive blood test that looks for small pieces of DNA from the donor organ in the patient s blood. We believe higher levels of this donor DNA may signal early rejection before damage becomes permanent.
Hypothesis:
We believe that measuring donor-derived DNA in the blood can help detect early signs of rejection a... Read More
