NCT00001373
This study is designed to explore the genetics and pathophysiology of diseases presenting with intermittent fever, including familial Mediterranean fever, TRAPS, hyper-IgD syndrome, and related diseases. The following individuals may be eligible for this natural history study: 1) patients with known or suspected familial Mediterranean fever, TRAPS, hyper-IgD syndrome or related disorders; 2) relatives of these patients; 3) healthy, normal volunteers 7 years of age or older. Patients will undergo a medical and family history, physical examination, blood and urine tests. Additional tests and procedures may include the following: 1. X-rays 2. Consultations with specialists 3. DNA sample collection (blood or saliva sample) for genetic studies. These might include studies of specific genes, or more complete sequencing of the genome. 4. Additional blood samples a maximum of 1 pint (450 ml) during a 6-week period for studies of white cell adhesion (stickiness) 5. Leukapheresis for collecting larger amounts of white cells for study. For this procedure, whole blood is collected through a needle in an arm vein. The blood flows through a machine that separates it into its components. The white cells are removed and the rest of the blood is returned to the body through another needle in the other arm. Patients may be followed approximately every 6 months to monitor symptoms, adjust medicine dosages, and undergo routine blood and urine tests. They will receive genetic counseling by the study team on the risk of having affected children and be advised of treatment options. Participating relatives will undergo a medical and family history, possibly with a review of medical records, physical examination, blood and urine tests. Additional procedures may include a 24-hour urine collection, X-rays, and consultations with medical specialists. A DNA sample (blood or saliva) will also be collected for genetic studies. Additional blood samples of no more than 550 mL during an 8-week period may be requested for studies of white cell adhesion (stickiness). Relatives who have familial Mediterranean fever, TRAPS, or hyper-IgD syndrome will receive the same follow-up and counseling as described for patients above. Normal volunteers and patients with gout will have a brief health interview and check of vital signs (blood pressure and pulse) and will provide a blood sample (up to 90 ml, or 6 tablespoons). Additional blood samples of no more than 1 pint over a 6-week period may be requested in the future.

NCT02830308
Background: There are many endocrine and metabolic-related conditions. Two well-known disorders include diabetes and thyroid disease. Some of these diseases are caused by a change in genes. Researchers want to identify the genes involved in these disorders. They hope this will help them learn more about these diseases. Objectives: To learn more about conditions that affect the hormone-secreting glands (endocrine glands) in adults. To train doctors to diagnose and treat people with endocrine or metabolic conditions. Eligibility: Adults age 18 years and older with a known or suspected endocrine disorder. Relatives ages 18 years and older. Doctors will review all requests and available medical records to determine final eligibility for the protocol. Design: Participants will have a medical history and physical exam. Most participants will have 1 visit, and may have follow up visits if necessary. They may have tests, surgery, or other procedures to help diagnose or treat their condition. These could include: * Blood, urine, and saliva tests * Imaging tests. These may include X-ray, ultrasound, or scans. * Sleep study * Medical photographs * Visits with other specialists at NIH Participants will provide blood, urine, saliva, or tissue samples. Some of these samples may be stored in the freezer for future studies. Participants may be asked to participate in genetic testing. They will give a blood or saliva sample for this.
NCT02203526
BACKGROUND: * Primary CNS lymphoma (PCNSL) is a rare subtype of diffuse large B-cell lymphoma. * The outcome for patients with this diagnosis is significantly worse than for that of systemic DLBCL. Most treatment approaches in the past have included high dose methotrexate and radiation treatment. * Most PCNSLs appear to be of activated B-cell (ABC) origin. * Ibrutinib is an inhibitor of Bruton s tyrosine kinase (BTK) and effective for systemic DLBCL of ABC origin. * We propose doing a study in which ibrutinib is combined with a novel chemotherapy platform called dose adjusted temozolomide, etoposide, doxil, dexamethasone, ibrutinib, rituximab (TEDDI-R). OBJECTIVE: \- Identify the maximum tolerated dose (MTD) of ibrutinib or the dose that achieves adequate CSF concentrations, whichever comes first, when ibrutinib is given with TEDDI-R. ELIGIBILITY: * Relapsed/refractory PCNSL. * Age greater than or equal to 18 years. * No pregnant or breast-feeding women. * Adequate organ function (defined in protocol). STUDY DESIGN: * This is a phase 1 study of 40 patients. * The study will have two components. 1. Phase 1: MTD of ibrutinib will be identified or the dose at which ibrutinib achieves a concentration of less than or equal to 100 nM in the CSF, when given in combination with TEDDI-R immuno-chemotherapy, whichever comes first. 2. Expansion cohort: Safety and tolerability of the regimen in relapsed/refractory or previously untreated PCNSL (DLBCL type) will be assessed at the final ibrutinib dose with TEDDI-R in 10 patients. Secondary objectives will be PFS and OS.
NCT01134614
This randomized phase II trial is studying how well giving ipilimumab with or without sargramostim (GM-CSF) works in treating patients with stage III or stage IV melanoma that cannot be removed by surgery (unresectable). Ipilimumab works by activating the patient's immune system to fight cancer. Colony-stimulating factors, such as sargramostim, may increase the number of immune cells found in bone marrow or peripheral blood and may help the immune system recover from the side effects of treatment. It is not yet known whether giving ipilimumab together with sargramostim is more effective than ipilimumab alone in treating melanoma.
NCT04793958
Study CA239-0006 is an open-label, randomized Phase 3 clinical trial comparing the efficacy of MRTX849 administered in combination with cetuximab versus chemotherapy in the second-line treatment setting in patients with CRC with KRAS G12C mutation.
NCT04613128
This is a prospective, multi-center observational study. The study is designed to measure the clinical effectiveness of elexacaftor, tezacaftor and ivacaftor (ETI) triple combination therapy in children (6-11 years of old) with one or more copies of the F508del mutation, study the effects of ETI across a number of CF disease manifestations, and collect specimens for future research. Subjects in the study will have one "before ETI" visit within 30 days before initiation of the therapy and five "after ETI" visits over a 24-month follow-up period. Participants who have participated in the original PROMISE Pediatric Sub-Study have the option of participating in a long-term extension with annual visits performed at the 36- and 48-month timepoints. The durability of the clinical and biological changes in the PROMISE Pediatric Sub-Study can be assessed with extended follow-up, which would enable the sub-studies to consider potential clinical consequences of the biological or physiological effects being studied. This work will help to inform long term prognosis and feasibility of certain clinical trials outcomes for interventional studies and may be useful when considering research priorities in drug development. The duration of participation for each subject is 24 months (with an additional 24 months if participants agree to the optional long-term extension). NOTE: FDA has granted approval for elexacaftor, tezacaftor and ivacaftor in the 6-11 age group.

NCT05765812
The primary purpose of the Phase 1 (Dose Escalation) of this study is to identify the dose-limiting toxicities (DLTs) of Debio 0123 combined with temozolomide (TMZ) (Arm A) and with TMZ and radiotherapy (RT) (Arms B and C) and to characterize the safety and tolerability of these combinations in adult participants with glioblastoma (GBM). Arm B which was previously added to the protocol, has been permanently halted per the safety monitoring committees' decision on the safety findings of this arm. The primary purpose of Phase 1 (Dose expansion) of the study is to assess the doses studied under Phase 1 (Dose Escalation) Arm A and identify the recommended dose (RD) for further development. The Phase 2 will start once the RD Phase 1 has been defined. The primary objective of Phase 2 is to assess the efficacy of Debio 0123 at the RD for further development in combination with TMZ, compared to the standard of care (SOC) in adult participants with GBM.
NCT00265798
This phase II trial is studying how well sorafenib works in treating patients with malignant gastrointestinal stromal tumor that progressed during or after previous treatment with imatinib mesylate and sunitinib malate. Sorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.
NCT04281134
This research study is for participants that have been diagnosed with intractable Obsessive -compulsive disorder (OCD). OCD is a persistent and oftentimes disabling disorder marked by unwanted and distressing thoughts (obsessions) and irresistible repetitive behaviors. OCD affects 2-3% of the US population, and is responsible for substantial functional impairment and increased risk of early death. The only established first-line treatments for OCD are cognitive-behavioral therapy (CBT) with exposure/response prevention and certain medications. About 30-40% of patients fail to respond and few experience complete symptom resolution. Up to 25% of patients have difficulty tolerating CBT and the risk of relapse after therapies remains large. For the most severe cases, neurosurgery (surgery in the brain), has long been the option of last resort. In this study the investigators want develop an adaptive Deep Brain Stimulation (aDBS) system to use in subjects with intractable (hard to control) OCD. Deep brain stimulation remains investigational for OCD patients and is not considered standard therapy. DBS involves the surgical implantation of leads and electrodes into specific areas of the brain, which are thought to influence the disease. A pack implanted in the chest, called the neurotransmitter, keeps the electrical current coursing to the brain through a wire that connects the neurotransmitter and electrodes. It is believed deep brain stimulation may restore balance to dysfunctional brain circuitry implicated in OCD. The goal of this study is to enhance current approaches to DBS targeting in the brain and to use a novel approach to find a better and more reliable system for OCD treatment. This current research protocol will focus on the completion of Phase Ib which will implant the RC+S system in 2 subjects.
