7 Clinical Trials for Various Conditions
Background: - Glucocorticoids are primary stress response hormones released from the adrenal gland when an individual is under stress. Chronic or ongoing elevation of these hormones due to prolonged stress or medical treatments can have numerous harmful effects. Researchers are interested in learning more about how these hormones affect cell growth, development, and death. To study glucocorticoid hormones, researchers plan to use the medication dexamethasone, which affects the parts of cells that respond to glucocorticoid hormones. Objectives: - To study glucocorticoid stress hormones in healthy individuals before and after receiving dexamethasone. Eligibility: * Healthy individuals at least 18 years of age. * Participants must not be using certain medications that may affect the dexamethasone test, including hormonal contraception, steroid-based drugs, and some antidepressants. Design: * This study will require an initial screening visit and a second study visit. The visits are estimated to require about 1 to 2 hours of participation over a period of up to 14 days. * Participants will be screened at visit 1 with a full physical examination and medical history, and an initial blood sample for testing. * For visit 2, participants will be asked to abstain from all food and drinks except for water for 12 hours before the appointment, and will take one tablet of dexamethasone 9 hours before the appointment. * Participants will have a second blood sample taken during visit 2, and will receive a snack after the blood is drawn.
This study offers evaluation and treatment of patients with a suspected connective tissue disorder. The protocol is not designed to test new treatments; rather, patients receive standard care. The study is designed to: 1) allow NICHD's staff to learn more about connective tissue disorders, 2) train physicians in the evaluation and treatment of these disorders; and 3) establish a pool of patients who may be eligible for other NICHD protocols for connective tissue disorders. (Participants in this protocol will not be required to join another study; the decision will be voluntary.) Patients of all ages with a suspected connective tissue disorder and their unaffected family members may be eligible for this study. Participants undergo diagnostic procedures that may include a medical history, physical examination, X-ray studies, eye examinations, and blood drawing, as well as other specialized tests, when needed. Additional tests may include: * Blood test for DNA genetic analysis * Skin biopsy: Removal of a small piece of tissue for microscopic examination. The area of skin selected for the biopsy is numbed and a small circle of skin, usually from the upper arm, is removed with a surgical cookie cutter-like instrument. * Magnetic resonance imaging (MRI): This test uses a strong magnetic field and radio waves to show structural and chemical changes in tissues. The patient lies on a table that slides into a narrow cylinder containing a magnetic field. Ear plugs are worn to muffle loud knocking and thumping sounds that occur with electrical switching of the magnetic fields. * Computed tomography (CT) scans: This test allows the doctor to view the organs inside the body in small sections. The patient lies in a doughnut-like machine. Scanning can be done from different angles, allowing a three dimensional picture of the part of the body being studied. It may be done with or without injection of a contrast material. * Referral to appropriate sub-specialists when potential complications are found.
The objective of this study is the development, implementation and management of a registry of patient data that captures clinically meaningful, real-world, data on the diagnosis, nature, course of infection, treatment(s) and outcomes in patients with complex disease globally.
This is a single-blind, placebo-controlled, randomized phase 2 study to evaluate the efficacy and safety of CBL-514 injections in participants with Dercum's Disease lipomas.
This Phase 2 study will be an open-label and randomized study to assess the efficacy and safety of CBL-514 in participants with Dercum's Disease lipomas.
The primary objective of this study is to establish the natural history of Farber disease (acid ceramidase deficiency) through the collection and analysis of retrospective and prospective data on patients diagnosed with Farber disease. All patients diagnosed with Farber disease are eligible, including both those who have and have not undergone hematopoietic stem cell transplantation (HSCT). Additionally, data and records from deceased patients will provide valuable retrospective data for this study. The secondary objective of the study is to establish a set of clinical data, laboratory data (biomarkers), and functional data potentially useful for: * Assessing the efficacy of HSCT and the efficacy of potential future therapies (for example with RVT-801, recombinant human acid ceramidase) in Farber disease * Characterizing changes in symptoms of patients over time * Characterizing distinct groups (phenotypes) within the patient population * Documenting the disease histories of individual patients to serve as intra-subject control data for those who may enroll in any future clinical studies with therapies for Farber disease The exploratory objectives of the study are: * To explore the relationship between patient disease activity or phenotype and specific ceramide levels or specific immunologic markers (cytokines/chemokines) in blood * To evaluate a standardized tool, the Farber Disease Natural History Instrument (FDNI), to be used for the collection of patient history information, data from clinical, laboratory, genetic, and functional studies, and data from review of medical records
Study to evaluate the safety and tolerability of intravenous (IV) administration of SBC-103 in participants with mucopolysaccharidosis III, type B (MPS IIIB, Sanfilippo B) with evaluable signs or symptoms of developmental delay.
