Filter by:This study will evaluate whether the drug mifepristone can improve the symptoms of Cushing's syndrome in people with ectopic adrenal corticotrophin hormone (ACTH) secretion. Cushing's syndrome occurs when the adrenal glands produce too much cortisol, a hormone that helps to regulate the body's use of salt and food. Excessive cortisol is usually the result of too much ACTH, the hormone that causes the adrenal glands to make cortisol. The extra ACTH is made either by a tumor in the pituitary gland (called Cushing's disease) or by a tumor somewhere else (called ectopic ACTH secretion). Mifepristone blocks the action of cortisol in the body. The drug has been used safely to treat a few people with Cushing's syndrome and patients with certain kinds of cancer, gynecological diseases and psychiatric disorders. People between 18 and 85 years of age with Cushing's syndrome caused by EXCESS ACTH secretion may be eligible for this study. Candidates are admitted to the hospital for evaluation to confirm Cushing's syndrome and to determine its cause. The evaluation includes blood and urine tests, imaging tests, dexamethasone and corticotropin-releasing hormone tests and inferior petrosal sinus sampling. Patients determined to have Cushing's syndrome due to ECTOPIC ACTH secretion undergo imaging studies (CT, MRI and a nuclear medicine scan) and begin mifepristone therapy. Participants remain in the hospital for the following tests and procedures: - Physical examination, electrocardiogram (EKG) and blood and urine tests - Completion of medical questionnaires - DEXA scan to determine bone mineral density and body composition - Glucose tolerance test - Urine pregnancy test and ultrasound to measure uterine lining thickness (for women) Patients take mifepristone by mouth 3 times a day. The dose is increased every week or so until symptoms improve or the highest dosage allowed is reached. Patients may remain in the hospital for all or part of the dose-finding part of the study. During this period (usually 2 to 4 weeks), blood pressure, glucose tolerance and blood chemistries are measured and EKG and urinalysis done every 5 to 14 days. When the mifepristone dose is stable patients remain on that dose for at least 2 weeks and are then re-evaluated. Patients then return to the hospital for evaluations every 3 months. Those who do well on the drug may continue to take it for up to 12 months.
Diabetes is more frequent in women with Turner syndrome. The purpose of this study is to see, in what ways the glucose metabolism is different in this study population. The hypothesis is that women with Turner Syndrome have an impaired insulin production (beta cell function).
The purpose of this study is to determine if laronidase is present in the breast milk of post-partum women receiving Aldurazyme® (laronidase) and the effects of Aldurazyme (laronidase) on the growth, development, and immunologic response of their breastfed infants.
The purpose of this study is to investigate over a 6 month period the effect of octreotide therapy on food intake, sense of hunger, body weight, body composition, efficiency of burning calories, biomarkers of weight regulation and growth hormone markers in children and young Adults with Prader-Willi Syndrome(PWS).
RATIONALE: Drugs used in chemotherapy, such as azacitidine, work in different ways to stop the growth of abnormal cells, either by killing the cells or by stopping them from dividing. Colony-stimulating factors, such as darbepoetin alfa and G-CSF, may increase the number of red blood cells and white blood cells found in bone marrow or peripheral blood and may help the immune system recover from the side effects of chemotherapy. Giving azacitidine together with darbepoetin alfa and G-CSF may be an effective treatment for myelodysplastic syndromes. PURPOSE: This clinical trial is studying how well giving azacitidine together with darbepoetin alfa and G-CSF works in treating patients with myelodysplastic syndromes.
RATIONALE: Giving total-body irradiation and chemotherapy, such as fludarabine and thiotepa, before a donor stem cell transplant helps stop the growth of cancer or abnormal cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. When healthy stem cells from a donor are infused into the patient, they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving antithymocyte globulin and removing the T cells from the donor cells before transplant may stop this from happening. PURPOSE: This phase II trial is studying how well a donor stem cell transplant works in treating patients with myeloid cancer or other disease.
This trial is designed to explore a modified dose and schedule of azacitidine in order to more effectively address the needs of patients with low-risk myelodysplastic syndromes (MDS), i.e., to alter the natural history of the disease without excessive toxicity or burden. The administration of erythropoietin is designed to influence the differentiation of primitive hematopoietic cells in which azacitidine has reversed the abnormal phenotype to red blood cells for patients in whom inadequate production of red blood cells is the major clinical issue.
RATIONALE: Vaccines made from cancer cells may help the body build an effective immune response to kill abnormal cells. PURPOSE: This clinical trial is studying how well vaccine therapy works in treating patients with myelodysplastic syndromes (MDS).
RATIONALE: Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of abnormal blood cells, either by killing the cells or by stopping them from dividing. Giving cyclophosphamide together with donor lymphocytes that have been treated in the laboratory may be an effective treatment for myelodysplastic syndromes or myeloproliferative disorders. PURPOSE: This clinical trial is studying the best dose of donor lymphocytes when given together with cyclophosphamide in treating patients with myelodysplastic syndromes or myeloproliferative disorders.
This phase I trial is studying the side effects and best dose of giving PDX101 together with 17-AAG in treating patients with metastatic or unresectable solid tumors or lymphoma. PDX101 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer. Drugs used in chemotherapy, such as 17-N-allylamino-17-demethoxygeldanamycin (17-AAG), work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving PXD101 together with 17-AAG may kill more cancer cells.
