Accelerated Phase Chronic Myelogenous LeukemiaBCR-ABL1 Positive38 more

This phase II trial studies how well fludarabine phosphate, cyclophosphamide, total body irradiation, and donor stem cell transplant work in treating patients with blood cancer. Drugs used in chemotherapy, such as fludarabine phosphate and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays to kill cancer cells and shrink tumors. Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. The donated stem cells may also replace the patient?s immune cells and help destroy any remaining cancer cells.

A Study of Rilzabrutinib in Adult Patients With Immune Thrombocytopenia (ITP)

Immune ThrombocytopeniaImmune Thrombocytopenic Purpura

This is a 2 part (Part A and B) adaptive, open-label, dose-finding study of PRN1008 in patients with ITP who are refractory or relapsed with no available and approved therapeutic options, with a platelet count <30,000/μL on two counts no sooner than 7 days apart in the 15 days before treatment begins. The dose-finding portion of the study has been completed. Part B treatment dose is 400 mg twice daily.

A Study to Assess Efficacy and Safety of Eltrombopag in Combination With a Short Course of Dexamethasone...

Immune Thrombocytopenia (ITP)

The purpose of this study is to compare the ability of eltrombopag in combination with a short course of high-dose dexamethasone to induce sustained response off treatment in patients with newly-diagnosed ITP versus 1-3 cycles of dexamethasone monotherapy. The unmet clinical need and the potential for eltrombopag when added to steroids to improve the treatment outcome and the potential to induce sustained response off treatment serve as the basis for clinical investigation of eltrombopag in first-line ITP.

Study of Romiplostim for Chemotherapy Induced Thrombocytopenia

Isolated Chemotherapy-induced Thrombocytopenia

This study is to determine if using weekly romiplostim injections will improve the patient's platelet count more effectively than simply waiting for the platelets to improve on its own, and if romiplostim will also allow the patient to receive at least 2 further cycles of chemotherapy without thrombocytopenia.

Phase III Study on HMPL-523 for Treatment of ITP

Primary Immune Thrombocytopenia (ITP)

The purpose of this study is to determine whether HMPL-523 (sovleplenib) is safe and effective in the treatment of chronic Immune Thrombocytopenic Purpura (ITP).

Characterization of New Candidate Genes in Cases of Human Inherited Thrombocytopenia (CATCH)

ThrombocytopeniaInherited Platelet Disorder

Circulating blood platelets are small cellular elements that help to control bleeding (a process called hemostasis) and to avoid hemorrhage when blood vessels are injured. Platelets originate from cells in the bone marrow, the megakaryocytes (MKs), following a complex process of morphological transformation and maturation, which finally leads to the production of blood platelets. Multiple genes are implicated in this process. Constitutive thrombocytopenia (CT) are rare hematological diseases characterized by a decreased number of circulating platelets that are often larger than normal, that may lead to more or less severe hemorrhagic events. However, CT can be difficult to diagnose and differentiate from various forms of acquired thrombocytopenia. The ultimate diagnosis for CT is thus based on the molecular diagnosis, obtained by identifying and characterizing the abnormal gene and protein. About 40 genes / proteins have been identified so far as causal in CT, however, in about half of the patients suspected to have CT, genomic analysis does not detect a variant in one of these genes, and etiology of CT thus remains unknown. But insuring the diagnosis of CT is important: it will avoid misdiagnosis and inefficient or deleterious therapeutic interventions, while allowing a proposal of an adapted curative/preventive medical action. At the Resource and Competence Center for Constitutional Hemorrhagic Diseases (CRCMHC) (University Hospital Robert Debré, Paris, France), the investigating team has evidenced in unrelated patients presenting with familial forms of thrombocytopenia and no known molecular diagnosis, variants of genes not yet described as formally implicated in the occurrence of CT. Molecular genetic evidence must be completed by functional studies. Such functional studies are conducted in a research laboratory from the National Institute for Health and Medical Research (Inserm), "Innovative Therapies in Haemostasis (IThEM)" (Faculty of Medical Sciences, University of Paris, Paris, France), and include: an evaluation of how blood progenitor cells mature into MKs, by comparing cells obtained from patients to those of members free of the disease (the latter taken as normal control subjects); an evaluation of platelet functionalities, such as ability to form a blood clot similar to what happens during hemostasis, with the aim to detect not only quantitative (number and size) but also any qualitative (functions) defects; an evaluation of the ultrastructure (the structure of intracellular components) and biochemistry of MKs and platelets, focusing on the molecular pathways the variant protein is implicated in. This clinical trial is aimed to precisely delineate the mechanism of action of newly identified CT genetic variants, and will fulfill the aims of (1) offering the patient(s) a formal molecular diagnosis of CT, (2) ameliorating patients' medical support, both for diagnosis and therapy, (3) providing patients and family members with a pertinent genetic counseling, and (4) expanding the validated panel of genes implicated in CT to be explored in new suspected cases of CT. It will also help in extending the basic knowledge of the process of MK and platelet formation.
