Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

Background: Cushing s disease is caused by excess ACTH hormone release by a benign tumor of the pituitary gland. It can lead to decreased quality of life and early death. The current best treatment for Cushing s disease is surgery. If surgery does not work or if the tumor returns, there are no more good treatment options. Vorinostat, which is approved to treat a type of lymphoma, might be a treatment option. Objective: To test vorinostat to see if it can kill tumor cells and change the number of hormones released in people with Cushing s disease. Eligibility: People ages 18 and older who have Cushing s disease and are scheduled for surgery under protocol 03-N-0164 to remove a tumor in their pituitary gland Design: Participants will be screened under protocol 03-N-0164. Participants will stay in the hospital for 8 days before their surgery. On the first day, participants will have a physical exam and blood tests. They will have their urine collected for testing all day. They will have an ECG: For this, small metal disks or sticky electrode pads will be placed on their chest to record heart activity. For the next 7 days, participants will have blood tests and all-day urine collection. They will drink at least 2 liters of fluid per day. They will take the study drug by mouth each morning. On the eighth day, participants will have their surgery. Leftover tissue will be collected for research. On the day they are discharged from the hospital, participants will have a physical exam and blood tests.
