(PIONEER) Study to Evaluate Efficacy and Safety of Avapritinib (BLU-285), A Selective KIT Mutation-targeted...
Indolent Systemic MastocytosisThis is a Phase 2, randomized, double-blind, placebo-controlled study comparing the efficacy and safety of avapritinib + best supportive care (BSC) with placebo + BSC in patients with indolent systemic mastocytosis (ISM) whose symptoms are not adequately controlled by BSC. The study will be conducted in 3 parts. All patients will receive treatment with avapritinib during Part 3 including those rolling over from the placebo group.
Observational Study for the Evaluation of Incidence of Systemic Mastocytosis in t(8;21) Acute Myeloid...
Systemic Mastocytosis With AHNMDAcute Myeloid Leukemia With T(8;21)(Q22;Q22)The observational study aimed at evaluating the incidence of systemic mastocytosis associated with t(8;21) AML in patients with de novo t(8;21) AML and their responses to first induction, and the prognosis from standard therapy.
Hydroxychloroquine in Isolated Cutaneous Mastocytosis Patients or Indolent Systemic Mastocytosis...
MastocytosisThe treatment of systemic mastocytosis has two main axes: Control of mast cell activation symptoms and The control of proliferation (accumulation) of mast cells. There is no standard treatment and no treatment has a marketing authorization for the treatment of monoclonal indolent mastocytosis.
Pregnancy and Medically Assisted Conception in Rare Diseases
Rheumatoid ArthritisSpondyloarthritis9 moreRare diseases frequently affect women of childbearing age. Pregnancy in these women has become less rare, but remains associated with high levels of complications. One obstacle to their optimal management during pregnancy is that there are no prospective studies of pregnancy during rare diseases and several connective tissue diseases. As a consequence, the management of these pregnancies is non-standardised in terms of treatment, monitoring (frequency of consultations, laboratory tests and ultrasound), and organisation of care. Moreover, although these women (all diseases combined) are frequently exposed to medications potentially incompatible with pregnancy, little is known about the frequency of these exposures and especially their consequences to mother and child. For these reasons, researchers and clinicians from different specialties created an interdisciplinary research group on pregnancy and rare diseases (GR2), intended to improve the management of these patients' pregnancies. Using a single computer server, the investigators plan to set up a large prospective study of pregnancies in patients with rare diseases: various forms of myositis, lupus, antiphospholipid syndrome, Sjogren syndrome, scleroderma, and inflammatory rheumatic diseases. The investigators objective is to analyse the complications of pregnancies in women with rare diseases and then to improve their management and their quality of life.
Myeloproliferative Neoplasms (MPNs) Patient Registry
Primary MyelofibrosisPolycythemia Vera16 moreThe mandate of this MPN registry is to collect clinical information, including molecular results, from consenting patients with a variety of MPNs at different time points during the course of their disease.
Study of Factors Regulating Mast Cell Proliferation
MastocytosisMonoclonal2 moreThis study will examine growth factors that promote and inhibit mast cell proliferation resulting in mastocytosis, a disease of excessive mast cells in the body. These cells can release chemicals that cause itching, blisters, flushing, bone pain and abdominal pain. Patients up to 80 years of age with mastocytosis may be eligible for this 1-day study. Participants will have one visit at NIH lasting up to 8 hours, during which they will undergo the following tests and procedures: Medical history and physical examination. Laboratory studies, if medically indicated. Blood tests to identify genetic changes important in the growth, development, and functioning of mast cells. Bone marrow aspiration and biopsy. For the bone marrow procedure, the skin over the hipbone and the outer surface of the bone itself are numbed with local anesthesia. Then, a special needle is inserted into the hipbone and about 1 tablespoon of bone marrow is drawn into a syringe. Another needle is inserted into the same area to collect a small piece of the bone marrow. Additional procedures may include allergen testing, urinalysis, and 24-hour urine collection. Participants will receive an evaluation of their mastocytosis.
Evaluation of the DALY on a Cohort of Patients With Indolent Systemic Mastocytosis
MastocytosisIndolent SystemicMastocytosis is a group of pathologies characterized by the accumulation and/or clonal proliferation of abnormal mast cells in various organs. The impact of mastocytosis on health, quality of life, the psychoaffective sphere and on professional life constitutes the burden of this disease. The DALY is the disability-adjusted life expectancy, which takes into account the life expectancy and the number of years "lost" due to illness, disability or early death. Due to the major impact of the disease this study evaluates the DALY in indolent mastocytosis patients
A Registry for Patients With Systemic Mastocytosis in China
Systemic MastocytosesThe Registry for Patients With Systemic Mastocytosis in China is a voluntary, observational database that will capture demographic, socioeconomic, and disease information with systemic mastocytosis. No experimental intervention is involved.
Ibrutinib in Treating Patients With Advanced Systemic Mastocytosis
Aggressive Systemic MastocytosisMast Cell Leukemia1 moreThis phase 2 trial studies ibrutinib to see how well it works in treating patients with systemic (affecting the entire body) mastocytosis that has spread to other parts of the body and usually cannot be cured or controlled with treatment (advanced). Systemic mastocytosis is a disease in which too many mast cells (a type of immune system cell) are found throughout the body. Mast cells give off chemicals such as histamine that can cause flushing (a hot, red face), itching, abdominal cramps, muscle pain, nausea, vomiting, diarrhea, low blood pressure, and shock. Ibrutinib may stop the growth of mast cells by blocking some of the enzymes needed for cell growth.
Cromoglicate in Mastocytosis
MastocytosisThe purpose of this exploratory study is to investigate the clinical efficacy of study drug (LP0074) in the treatment of Mastocytosis. The trial will be performed as a left/right comparison study in male/female subjects with mastocytosis, in a prospective, double-blinded, randomised, single centre setting.
