Filter by:This is a non-interventional, multinational, multi-center post-marketing study, to further document the safety and efficacy of pasireotide s.c. administered in routine clinical practice in patients with Cushing's disease. Patients with Cushing's disease and treated with pasireotide s.c. alone and in combination with other therapies will be monitored. For this study, each enrolled patient will be followed up for 3 years after enrollment. Patients who permanently discontinue pasireotide s.c. prior to completing the 3-year observation period will be followed up for 3 months after the last dose of pasireotide s.c.
Cushing syndrome refers the manifestations induced by chronic glucocorticoid excess and may arise from various causes. Iatrogenic Cushing syndrome accounts for most patients, when they are given exogenous glucocorticoid treatment. In contrast, spontaneous Cushing syndrome results from endogenous glucocorticoid over-secretion. Although Cushing disease is rare, it is the most common cause of spontaneous Cushing syndrome. The patient with Cushing disease has a pituitary corticotroph adenoma, which overproduces adrenocorticotropic hormone (ACTH). ACTH then stimulates adrenal gland to over-secret glucocorticoid. Patients with untreated Cushing disease were shown to have poor prognosis, estimated a 5-year survival rate of 50%. The first line treatment is tumor resection. Other managements include radiotherapy, medication and bilateral adrenalectomy. The initial remission rate is high (66-90%). However, some patients encounter with disease recurrence during follow-up. The aim of this study is to clarify the factors associated with the recurrence after treatment. In this study, we will review the patients with Cushing disease thoroughly and analyze associated predisposing factors. These risk factors can remind the clinical physician to early detect the recurrent disease in these patients, and further prevent morbidity and mortality in their later lives.
The study aimed to confirm long-term efficacy and safety of LCI699 for the treatment of patients with Cushing's disease. It was a pivotal trial which supported the registration of LCI699 for the treatment of patients with Cushing's disease in the US and the EU. This is a phase lll, multi-center, double-blind, randomized withdrawal study of LCI699 following a 24 week, single-arm, open-label dose titration and treatment period which evaluated the safety and efficacy of LCI699 for the treatment of patients with Cushing's disease.
The study was designed to investigate the optimal management of hyperglycemia developed during pasireotide treatment in participants with Cushing's disease or Acromegaly, which was not manageable with metformin. This was a Phase IV, multi-center, randomized, open-label study. Eligible patients started pasireotide subcutaneously (s.c.) for Cushing's disease and pasireotide LAR (long-acting release) for Acromegaly. Participants being treated with pasireotide s.c or LAR at screening were eligible as long as they met protocol criteria during the screening period. If previously normo-glycemic participants experienced an increase in their fasting blood glucose and met the criteria for diabetes while on pasireotide, they started anti-diabetic treatment using metformin. If they continued to have elevated blood glucose above target on metformin within the first 16 weeks, they were randomized in a 1:1 ratio to receive treatment with incretin based therapy or insulin for approximately 16 weeks. Participants who continued to receive clinical benefit after completing the Core Phase could enter an optional Extension Phase if pasireotide was not commercially available in their country or a local access program was not available to provide drug. Patients continued in the Extension Phase until the last participant randomized in the Core Phase completed 16 weeks of treatment post-randomization.
The purpose of this study is to allow continued use of pasireotide in patients who are on pasireotide treatment in a Novartis-sponsored study and are benefiting from the treatment as judged by the investigator.
This study provided access to pasireotide sc in patients with Cushing's disease.and provided additional information for safety and efficacy of pasireotide s.c.
This is a prospective, multi-center observational study designed to address patient-reported nasal outcomes in adults undergoing endoscopic and microscopic surgical removal of pituitary tumors. The primary objective of this study is to determine the difference in nasal outcomes by using the Anterior Skull Base (ASK) Nasal survey between patients treated with endoscopic surgical technique and those treated with microscopic surgical technique. Patients will be given the ASK Nasal survey to assess their nasal functioning and overall health before their surgery, and at post-operative visits 1-2 weeks, 3 months, and 6 months.
Background: - Cushing s disease can be caused by a tumor of the pituitary gland, a small gland about the size of a pea located at the base of the brain. These tumors produce high levels of hormones, which cause obesity, diabetes, and growth problems. The cure for this type of Cushing s disease is to have surgery that removes the tumor but leaves the pituitary gland alone. Currently, magnetic resonance imaging scans are the best way to find these tumors. However, many of these tumors do not show up on the scan. - Positron emission tomography (PET) scans use radioactive chemicals to light up parts of the body that are more active, such as tumors. Researchers want to try to make the small Cushing s disease tumors more active to help them show up on the scans. A special hormone will be given before the scan to make the tumors more active. Objectives: - To test the use of hormone stimulation to improve brain scans for Cushing s disease tumors. Eligibility: - Individuals at least 8 years of age who will be having surgery to remove Cushing s disease tumors. Design: - Participants will be screened with a medical history, physical exam, blood and urine tests, and imaging studies. - They will have three brain scans before surgery. The first scan is a magnetic resonance imaging scan to show a full picture of the brain. The second and third scans are PET scans. - The first PET scan will be given without the special hormone. The second PET scan will be done more than 24 hours but less than 14 days after the first PET scan. The second PET scan will be given with the special hormone. - Participants will have tumor removal surgery through another study protocol.
This is a randomized, double-blind, multicenter, phase III study to evaluate the safety and efficacy of 2 dosing regiments of Pasireotide long acting release (LAR) in patients with Cushing's disease.
This is a compassionate use study. In addition to providing compassionate use access to mifepristone, objectives of the study will be to evaluate the safety and utility of mifepristone in the treatment of the signs and symptoms of endogenous Cushing's syndrome when given on a compassionate use basis. The study will only enroll subjects whose physicians have determined that medical treatment is needed to control the symptoms or signs of hypercortisolemia.
