A Trial Comparing Unrelated Donor BMT With IST for Pediatric and Young Adult Patients With Severe Aplastic Anemia (TransIT, BMT CTN 2202)
Recruiting
Severe Aplastic Anemia (SAA) is a rare condition in which the body stops producing enough new blood cells. SAA can be cured with immune suppressive therapy or a bone marrow transplant. Regular treatment for patients with aplastic anemia who have a matched sibling (brother or sister), or family donor is a bone marrow transplant. Patients without a matched family donor normally are treated with immune suppressive therapy (IST). Match unrelated donor (URD) bone marrow transplant (BMT) is used as a... Read More

Therapeutic Effect of Cytoreductive Radical Prostatectomy in Men With Newly Diagnosed Metastatic Prostate Cancer
Recruiting
This randomized phase II trial studies how well surgical removal of the prostate and antiandrogen therapy with or without docetaxel work in treating men with newly diagnosed prostate cancer that has spread to other places in the body. Androgens can cause the growth of prostate cancer cells. Antiandrogen therapy may lessen the amount of androgens made by the body. Drugs used in chemotherapy, such as docetaxel work in different ways to stop the growth of tumor cells, either by killing the cells, b... Read More

Study of the Safety, Tolerability, Electrophysiological Effects and Efficacy of DMT in Humans
Recruiting
The goal of this phase 1 study is to investigate the safety and efficacy of dimethyltryptamine (DMT) in individuals with depression and healthy controls. We hypothesize that administration of DMT will result in decreases in depression, associated symptoms, and neuroplastic changes in depressed subjects. We expect that DMT will induce changes in neuroplasticity as indexed using electroencephalographic (EEG) measures and tasks in both depressed individuals and healthy volunteers, though to differe...
