Filter by: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.
Multicenter, open-label, non-comparative study to evaluate the pharmacokinetics, pharmacodynamics, and tolerability of osilodrostat in children and adolescent patients with Cushing's disease.
The purpose of this study is to investigate the treatment and natural history of pituitary disease. We have a longstanding interest in pituitary disease including acromegaly, central diabetes insipidus, and nonfunctioning pituitary adenoma. We will continue to follow patients and recruit new patients for treatment and follow-up. Blood and pituitary tumor tissue (when available through clinical care) will be saved for future analyses related to pituitary disease.
The purpose of this study is to follow participants with Cushing's syndrome during the course of their routine care and to form a data registry to study long term participant outcomes.
The USP8 gene and its downstream target, epidermal growth factor receptor (EGFR), is a potential therapeutic target of Cushing disease. The EGFR inhibitor, Gefitinib, has been shown to reduce the production of ACTH both in vitro and in vivo, especially in USP8-mutated corticotrophin adenomas. The investigators hypothesize that Gefitinib will suppress pituitary corticotroph tumor ACTH production and normalize urinary free cortisol levels in patients with USP8-mutated Cushing's disease. Gefitinib is an FDA approved drug used to treat non-small cell lung cancer. However, in this study, the drug will be used to treat corticotrophin adenoma.
The objective of this pilot study is to establish the safety and tolerability of short-term therapy with bexarotene in patient's with Cushing's disease, and study the clinical, biochemical, and cellular effects of a preoperative five-day course of bexarotene in these patients before undergoing transsphenoidal surgery.
