Active clinical trials for "Pituitary Neoplasms"

This is a phase II, open-label, 12-month pilot study in 10 patients with silent corticotroph pituitary tumors testing the hypotheses that Pasireotide long-acting release (LAR) treatment of patients with silent corticotroph pituitary tumors and elevated plasma Proopiomelanocortin (POMC) levels will reduce plasma POMC levels and this will be associated with a reduction in pituitary tumor size. Pasireotide LAR 40 mg will be administered monthly. Baseline and monthly visits on therapy will monitor plasma levels of POMC, other pituitary function, safety labs, glucose tolerance, physical examination, and visual fields. Pituitary magnetic resonance imaging (MRI) will be done at baseline, 6 months and 12 months of therapy. The eligible patient population will consist of adult patients with known silent corticotroph pituitary tumors and elevated plasma levels of POMC.

This phase I/II clinical trial is studying the side effects and best dose of gamma-secretase inhibitor RO4929097 and to see how well it works in treating young patients with relapsed or refractory solid tumors, CNS tumors, lymphoma, or T-cell leukemia. Gamma-secretase inhibitor RO4929097 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

This is an open label study to assess the efficacy of capecitabine (CAP) and temozolomide (TMZ) in recurrent pituitary adenomas. There will be a safety run-in of at least three patients to establish any dose limiting toxicities. Enrolled patients will receive treatment in 28-day cycles: capecitabine 1500mg/m2 per day (divided into two doses with maximum daily dose of 2500mg) on days 1 through 14 and oral temozolomide 150 to 200 mg/m2 on days 10 through 14. This will be followed by 14 days off treatment. MRI imaging will be completed after every two cycles. Treatment repeats every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity.

The purpose with this study is to test a digital patient-provider communication tool for symptom and needs management among patients with chronic health conditions.

RATIONALE: Rosiglitazone may help pituitary adenoma cells become more like normal cells, and grow and spread more slowly. PURPOSE: This phase II trial is studying how well rosiglitazone works in treating patients with newly diagnosed or residual or recurrent pituitary adenoma.

Over the past 30 years, endoscopic transnasal techniques have gained a major interest, and anatomic limits have been widened in order to extend neurosurgical applications. For many years, robotic-assisted surgery using the da Vinci system (Intuitive Surgical Inc, Sunnyvale, California, USA) has been greatly developed, especially in urology and gynecology. Robotic-assisted surgery has been performed for pharyngeal and laryngeal cancers in a minimally invasive perspective. A robot-assisted preliminary series demonstrated the ability to approach the sella via oral approach without traumatic injury of nasal or oral cavity. Transoral approach avoids the complications of the endonasal resection: synechia, rhinitis sicca anterior, primary and secondary atrophican rhinitis, and empty nose syndrome. The investigators recently published a cadaveric study of transoral robotic-assisted skull base surgery to approach the sella turcica (Neurosurgical Rev. 2014; 37:609-17). In this study, the investigators will propose a new minimally invasive technique of pituitary surgery by transoral approach assisted by the da Vinci robot in patients with pituitary adenoma.

To determine the outcomes of patients with different pituitary disorders whether they are managed medically, surgically or expectantly.

This study will assess the effectiveness and safety of pasireotide long-acting release in patients who have rare tumors of neuroendocrine origin.

Background: Cushing s disease is caused by a pituitary gland tumor. Patients with Cushing s disease suffer obesity, diabetes, osteoporosis, weakness, and hypertension. The cure is surgery to remove the pituitary tumor. Currently, MRI is the best way to find these tumors. But not all tumors can be seen with an MRI. Researchers hope giving the hormone CRH before a PET scan can help make these tumors more visible. Objective: To test whether giving CRH before a PET scan will help find pituitary gland tumors that might be causing Cushing s disease. Eligibility: People ages 8 and older with Cushing s disease that is caused by a pituitary gland tumor that cannot be reliably seen on MRI Design: Participants will be screened with their medical history, a physical exam, an MRI, and blood tests. Participants will have at least one hospital visit. During their time in the hospital, they will have a physical exam and a neurological exam. They will have a PET scan of the brain. A thin plastic tube will be inserted into an arm vein. A small amount of radioactive sugar and CRH will be injected through the tube. Participants will lie in a darkened room for about an hour and be asked to urinate. Then they will lie inside the scanner for about 40 minutes. After the scan, they will be asked to urinate every 2-3 hours for the rest of the day. Blood will be drawn through a needle in the arm. Participants will have surgery to remove their tumor within 3 months after the scan. Participants will then continue regular follow-up in the clinic.
