Filter by:This is a Phase 1, open-label, dose-escalation study designed to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and antineoplastic activity of avapritinib (also known as BLU-285), administered orally (PO), in adult patients with advanced systemic mastocytosis and other relapsed or refractory myeloid malignancies. The study consists of 2 parts:, dose-escalation (Part 1) and expansion (Part 2).
The investigators wish to evaluate the association between tryptase values as well as c-Kit mutation and adverse effects in the course of immunotherapy. The investigators also intend to assess the effect of immunotherapy on tryptase levels.
This is a randomized, placebo- and active-controlled, 2-period crossover, 2 cohort study in adult patients with indolent systemic mastocytosis (ISM). The purpose of the study is to determine the efficacy and safety profile of PA101 delivered via eFlow high efficiency nebulizer in patients with ISM who are symptomatic despite using standard treatments.
Rare 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.
The hypothesis of the study is that Bone Marrow Tryptase (MT) level is a diagnostic marker of Systemic Mastocytosis (SM). Determination of the bone marrow tryptase in Bone Marrow Aspirate (BMA) could be a new diagnostic criteria for systemic mastocytosis with sensitivity close to 100% and a low false negative rate. This new test could be useful to improve the ability to diagnose accurately systemic mastocytosis (in particular the indolent forms). Because of its limited invasiveness compared to bone marrow biopsy, it could also be considered as a test performed before bone marrow biopsy. Only patients with high bone marrow tryptase would then undergo bone marrow biopsy. In the future and if validated by this study, bone marrow tryptase could be a useful marker of mast cell load and help to monitor the efficacy of treatment in systemic mastocytosis.
This 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.
The purpose of this study is to explore the key symptoms of individuals with systemic mastocytosis. Interviews of enrolled individuals will be conducted to learn about the disease symptoms and condition. The interview will last approximately 60 minutes and will be conducted by a trained interviewer, be audio-recorded (with patient consent), and all information provided by the patient will be treated confidentially and made anonymous so that it is non-identifiable. The interview may be conducted face-to-face, over the phone, or virtually via Skype, a free video conferencing program, depending upon the patient's geographic location. Patients will be compensated for their participating time. This is not a medication-related study, and no medication will be distributed or tested during this study. Participation in this study will not affect any treatment or assistance that a patient currently receives or may receive in the future.
Rationale: Patients with indolent or smoldering systemic mastocytosis can have severe disabling symptoms. Almost all patients have fatigue, a compromised quality of life, hampering normal functioning. Because this form of mastocytosis is not considered life-threatening, mast cell eradication has never been applied and patients receive only symptomatic therapy with histamine blockers. Midostaurin, a c-KIT inhibitor has shown activity regarding symptom control and decrease of malignant mast cells in patients with aggressive systemic mastocytosis (ASM) or mast cell leukemia
This pilot clinical trial studies brentuximab vedotin in treating patients with advanced systemic mastocytosis or mast cell leukemia. Monoclonal antibodies, such as brentuximab vedotin, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them
The 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.
