Active clinical trials for "Pituitary Diseases"

The registry of this study was subjected to patients who were radiologically diagnosed with a non-malignant brain tumor at Seoul National University Hospital since 2001, and who have had magnetic resonance (MR) re-examination after first MR exam or will be re-examined because it was determined that immediate treatment would not be needed at the first visit to the hospital. In all MRs taken by patients, the date of imaging and the volume of the tumor are measured, and we aim to establish a natural growth history for non-malignant brain tumors.

Epidemiologic studies have revealed a tremendous increase in the prevalence of pituitary disease and related mortality worldwide. In order to meet all the challenges in the treatment of pituitary disease in China, CAPASITY was founded in 2020. The objective of CAPASITY is to launch a pituitary disease management model based on the Internet health information platform. It allows the application and evaluation of pituitary disease treatment strategies at multiple centers. The proprietary electronic medical database will help the dynamic big-data analysis in epidemiology of pituitary disease, diagnosis, and treatment.

At present there are no recommendations regarding the possibility of discontinuing treatment in cases of recurrent acromegaly with good hormonal control. Discontinuation of treatment is therefore most often decided by the practitioner, on the basis of his experience and knowledge of the patient, the long-term course with somatostatin analogues being very little described. Thus, although hormonal control is achieved in a majority of cases under medical treatment, we do not know if it is possible to stop treatment and in this case how the pathology evolves. It would appear that approximately 40% of patients defined as very good responders to somatostatin analogues may gradually space their injections.

Hyponatremia is defined as sodium below the normal range of 135-145. Symptomatically, it can cause patients to experience a wide range of symptoms including lethargy, headache, nausea, vomiting and in severe cases coma and even death. The goal of this study is to prospectively compare two approaches to the postoperative fluid management of patients undergoing transsphenoidal resection of a pituitary tumor or cyst to decrease the occurrence of postoperative delayed hyponatremia. One group will be placed on moderate fluid restriction and the other group will be placed on ad lib fluid intake.

DNA methylation is one of the important ways of protein post-translational modification.Pituitary adenoma (PA) is a benign neuroendocrine tumor that originates from adenohypophysial 45 cells, and accounts for 10%-20% of all primary intracranial tumors. However some PAs can present with high invasiveness and irregular growth, which tend to compresses the optic chiasm and third ventricle, encase the internal carotid artery, and affect hormone secretion from the pituitary gland and hypothalamus. In this study we focus on the mechanism of DNA methylation on the invasiveness of pituitary tumors.

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 to age-related differences to the response of a combined pituitary stimulation test with TRH, LHRH and ACTH.

The purpose of this study is to observe predictors of pituitary tumor recurrence and markers of persistent disease activity in patients harboring pituitary mass lesions of all types.

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.
