Active clinical trials for "Mastocytosis, Systemic"

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).

This is a Phase 1, open-label, first-in-human (FIH) dose-escalation study designed to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary antitumor activity of DCC-2618, administered orally (PO), in adult patients with advanced malignancies. The study consists of 2 parts, a dose-escalation phase, and an expansion phase. All active patients (from both dose-escalation and expansion phases) will then transition into an extension phase.

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 objective of this study is to compare the safety and efficacy of masitinib (AB1010) to placebo in patients with mastocytosis with handicap.

The purpose of this trial is to assess the efficacy, safety, tolerability, biologic activity, and pharmacokinetics of AMN107 in six groups of patients with one of the following conditions: Relapsed/refractory Ph+ Acute lymphoblastic leukemia (ALL) (arm 1) Group A - Imatinib failure only (arms 2, 3 and 4) imatinib-resistant or intolerant CML - Chronic Phase (CP) imatinib-resistant or intolerant CML - Accelerated Phase (AP) imatinib-resistant or intolerant CML - Blast Crisis (BC) Group B - Imatinib and other TKI failure (arms 2, 3 and 4) imatinib-resistant or intolerant CML - Chronic Phase (CP) imatinib-resistant or intolerant CML - Accelerated Phase (AP) imatinib-resistant or intolerant CML - Blast Crisis (BC) Hypereosinophilic syndrome/chronic eosinophilic leukemia (HES/CEL) (arm 5) Systemic mastocytosis (Sm) (arm 6)

This is a Phase 1 study to investigate the safety and tolerability of AK002 in patients with indolent systemic mastocytosis (ISM).

The purpose of this study was to determine the efficacy and safety of twice daily (bid) oral midostaurin in patients with Aggressive Systemic Mastocytosis (ASM) or Mast Cell Leukemia (MCL) with or without an Associated Hematological clonal Non-Mast cell lineage Disease (AHNMD).

The aim of this study is to evaluate the efficacy in terms of clinical and biological response rates of Imatinib Mesylate therapy in patients with systemic mastocytosis lacking KIT mutations.

RATIONALE: Drugs used in chemotherapy, such as 17-N-allylamino-17-demethoxygeldanamycin (17-AAG), work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. PURPOSE: This phase II trial is studying how well 17-AAG works in treating patients with systemic mastocytosis.

This study will investigate the safety and effectiveness of an experimental stem cell transplant procedure for treating mastocytosis-a disease of abnormal mast cell growth. Patients often feel faint, have skin problems, joint and bone pain, low blood counts and enlarged liver, spleen or lymph nodes. As yet, there is no cure for mastocytosis, and treatment is aimed at controlling symptoms. Stem cells are cells produced by the bone marrow that mature into the different blood components-white cells, red cells and platelets. Transplantation of allogeneic (donated) stem cells is a mainstay of therapy for some forms of leukemia. Patients first receive intensive chemotherapy and radiation to rid the body of cancer cells. This "conditioning" is followed by transplantation of donated stem cells to generate new, healthy bone marrow. In addition to producing the new bone marrow, the donated cells also fight any residual tumor cells that might have remained in the body. This is called a "graft-versus-tumor" effect. This study will examine whether a stem cell transplant from a healthy donor can similarly target and destroy mast cells in a "graft-versus-mast cell" effect. Also, to try to reduce the harmful side effects of chemotherapy and radiation, this study will use lower dose chemotherapy and no radiation. Patients with advanced mastocytosis between 10 and 80 years old may be eligible for this study. They will be tested for HLA type matching with a sibling and will undergo a medical history, physical examination and several tests to determine eligibility for the study. Participants will undergo apheresis to collect lymphocytes (a type of white blood cell) for immune function tests. In this procedure, blood is drawn through a needle in the arm, similar to donating a unit of blood. The lymphocytes are then separated and collected by a cell separator machine, and the rest of the blood is returned through a needle in the other arm. Patients will also have a central venous line (flexible plastic tube) placed in their upper chest leading to a vein. This line will remain in place throughout the transplant and recovery period and will be used to transfuse blood components, administer medicines, infuse the donated stem cells, and draw blood for tests. Patients will begin conditioning with cyclophosphamide, starting 7 days before the transplant, and fludarabine, starting 5 days before the transplant, to prevent rejection of the donated cells. From 1 to 3 days after the chemotherapy is completed, the stem cells will be transfused through the central venous line. Also, from 4 days before the transplantation until about 3 months after the procedure, patients will receive cyclosporine and mycophenolate mofetil-drugs that help prevent both rejection of the donated cells and attack by the donor cells on the patient's cells (called graft-versus-host disease). Patients will stay in the hospital about 20 to 30 days after the transplant. After discharge, they will continue to take antibiotics, cyclosporine and mycophenolate mofetil at home. If the mastocytosis progresses, cyclosporine and mycophenolate mofetil will be tapered over 4 weeks. If the mastocytosis persists, patients may receive additional transfusions of donor lymphocytes to help kill the mast cells. Patients' progress will be followed weekly or twice weekly for 3 months, then at 6, 12, 18, 24, 30, 36, 48 and 60 months after transplant, and then twice a year for various tests, treatments and examinations.
