Filter by:The MPL gene is implicated in two groups of hematological pathologies: congenital amegakaryocytic thrombocytopenia (CAMT) and Phi negative myeloproliferative neoplasia (MPN). Fifty germline mutations have been identified in CAMT, yet only a dozen activating mutations have been described in MPN. Most are somatic, distributed mainly in the transmembrane (TM) and juxtamembrane (JM) domains. However, a few rare germline mutations located in the extracellular domain (ECD) have also been reported: K39N, R102P and P106L. Next generation sequencing technology has been used to study the complete MPL gene, identifying numerous variants, most of unknown significance. The study investigators have a series comprising 41 variants of unknown significance, whose allelic frequencies suggest a germline origin for 80% of them. Their distribution within the MPL gene is similar to that of inactivating mutations, except that they were discovered in the context of suspected myeloproliferative disease. Characterizing the activity of these variants would confirm the diagnosis of MPN, opening the door to specific treatment (cytoreductive, JAK2 inhibitor or interferon). It also has an important prognostic value, particularly in the case of MPN, for which life expectancy varies from 5 to 7 years, with terminal progression to acute myeloid leukemia (AML in 15 to 20% of cases) or bone marrow failure. Using a battery of functional assays, this study aims to characterize these variants.
This clinical trial tests whether a geriatric optimization plan (GO!) works to improve survival in patients over 60 with a hematologic malignancy or bone marrow failure syndrome eligible for allogeneic hematopoietic cell transplant. GO! focuses on creating a tailored and specific plan for each patient to make changes in their daily lives. These may include changes to their diet, sleep, activity, medicines, or even referrals to other providers depending on the patient's needs. Studying survival and quality of life in patients over 60 receiving an allogeneic hematopoietic cell transplant may help identify the effects of treatment.
This is a multi-center, open-label extension study to assess the long-term safety and efficacy of bomedemstat (MK-3543, formerly called IMG-7289) administered orally once daily in participants with an MPN who participated in a prior bomedemstat study such as, but not limited to, IMG-7289-CTP-102 and IMG-7289-CTP-201 (referred to hereafter as 'feeder studies').
This study will evaluate whether a geriatric assessment can lead to better treatment outcomes in older patients (age 60+) with a myeloid malignancy including acute myeloid leukemia, ,myelodysplastic syndromes, myeloproliferative neoplasms, or related blood disorders who are going to receive chemotherapy or another treatment to prepare the body for an allogeneic hematopoietic stem cell transplant (allo-HCT). The geriatric assessment includes looking at patients' cognitive function (thinking processes), physical function, mobility (ability to move the body), mood, nutrition, and current medications to help decide the type of treatment they'll receive. Another purpose of this study is to see whether use of the geriatric assessment improves participants' quality of life. We will evaluate participants' quality of life through questionnaires.
Patients with Myeloproliferative neoplasms are at particular risk for developing arterial and venous thrombosis, especially thrombosis in the splanchnic venous system. The patho-physiology and natural history of MPN related SVT is poorly understood and treatment algorithms vary greatly. This is of considerable importance since the morbidity and mortality in this group of patients is high. This study aims to observe patients with MPN related SVT over a period of five years to document their clinical progress. Methods of observation include clinical assessment, standard investigations and laboratory based research investigations
This is an open-label, multi-center Phase 1 study of LY3410738, an oral, covalent isocitrate dehydrogenase (IDH) inhibitor, in patients with IDH1 and/or IDH2-mutant advanced hematologic malignancies who may have received standard therapy
This research study is studying the RGI-2001 for preventing Graft-vs-Host Disease (GVHD) in people with acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), myelodysplastic syndrome (MDS), myeloproliferative disorders (MPN), chronic myelomonocytic leukemic (CMML), chemosensitive hodgkin lymphoma (HL), or Non-Hodgkin lymphoma (NHL).who will have a blood stem cell transplantation. - GVHD is a condition in which cells from the donor's tissue attack the organs. - RGI-2001 is an investigational treatment
Myeloproliferative neoplasms (MPNs) are blood disorders that occur when the body makes too many white or red blood cells, or platelets. This overproduction of blood cells in the bone marrow can create problems for blood flow and lead to various symptoms. One of the major problems is the formation of blood clots. These may form in the veins of a patient's legs or arms where they cause leg or arm pain, swelling or difficulty walking. These clots may travel to the lung and then cause chest pain, shortness of breath and sometimes death. Blood clots can also lead to poor or no blood flow to one's heart, brain, or other organs, causing damages that cannot be easily or ever repaired, such as stroke or heart attack. Patients diagnosed with certain types of MPN are associated with a higher risk of developing blood clots and related complications. For this reason, MPN patients are usually treated with low-dose aspirin, a common drug used for blood clot prevention, on long-term basis to prevent the formation of blood clots and other complications. However, recent studies also show that the risk of blood clots remains elevated in MPN patients treated with aspirin, and there may not be improvement or reduction in fatal or other events that are associated with blood clots. In addition, since this medical condition is rare, so there's a lack of studies done with high quality results to help physicians decide the best treatment plan for these patients. The study drug, apixaban, is a new type of orally-taken blood thinner that has been shown to be effective and safe for prevention and treatment of blood clots in various patient populations. The investigators will evaluate whether apixaban is safer and/or better at preventing blood clots and other complications in MPN patients compared to aspirin.
This is a single arm, phase II trial of HLA-haploidentical related hematopoietic cells transplant (Haplo-HCT) using reduced intensity conditioning (fludarabine and melphalan and total body irradiation). Peripheral blood is the donor graft source. This study is designed to estimate disease-free survival (DFS) at 18 months post-transplant.
This phase I/II trial studies the side effects and best dose of gilteritinib and to see how well it works in combination with azacitidine and venetoclax in treating patients with FLT3-mutation positive acute myeloid leukemia, chronic myelomonocytic leukemia, or high-risk myelodysplastic syndrome/myeloproliferative neoplasm that has come back (recurrent) or has not responded to treatment (refractory). Drugs used in chemotherapy, such as azacitidine, 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. Venetoclax may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Gilteritinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving azacitidine, venetoclax, and gilteritinib may work better compared to azacitidine and venetoclax alone in treating patients with acute myeloid leukemia, chronic myelomonocytic leukemia, or myelodysplastic syndrome/myeloproliferative neoplasm.
