The investigators would like to conduct a retrospective study in five centers in France in the goal to evaluate the survival of patients receiving allogeneic hematopoietic stem cell transplantation for myelofibrosis.
The presence of IDH mutation is associated with worse survival in patients with myelofibrosis. Moreover IDH mutations are among the most frequently encountered events in MPNs that have progressed to acute myeloid leukemia. Ruxolitinib, a JAK1/2 inhibitor, and enasidenib an IDH2 inhibitor are effective and tolerable treatments for patients with myelofibrosis (MF) and acute myeloid leukemia (AML), respectively. The study team hypothesize that the combination of these agents in patients with MPN with an IDH2 mutation will improve the overall clinical response to therapy.
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.
9-ING-41 has anti-cancer clinical activity while not causing myelosuppression, and has both pre-clinical anti-fibrotic activity and activity against myelofibrosis. This Phase 2 study will study its efficacy in patients with advanced myelofibrosis.
This phase IIB, open-label, multicenter study evaluated the efficacy and safety of oral Jaktinib Hydrochloride Tablets in Intermediate-risk and High-risk Myelofibrosis and Previously Treated With Ruxolitinib. The experiment is divided into two parts: dose exploration and extended research.
MOMENTUM is a randomized, double-blind, active control Phase 3 trial intended to confirm the differentiated clinical benefits of the investigational drug momelotinib (MMB) versus danazol (DAN) in symptomatic and anemic participants who have previously received an approved Janus kinase inhibitor (JAKi) therapy for myelofibrosis (MF). The purpose of this clinical study is to compare the effectiveness and safety of MMB to DAN in treating and reducing: 1) disease related symptoms, 2) the need for blood transfusions and 3) splenomegaly, in adults with primary MF, post-polycythemia vera MF or post-essential thrombocythemia MF. The study is planned in countries including, but not limited to: Australia, Austria, Belgium, Bulgaria, Canada, Czech Republic, Denmark, France, Germany, Hungary, Israel, Italy, New Zealand, Poland, Romania, Singapore, South Korea, Spain, Sweden, Taiwan, United Kingdom (UK) and United States (US). Participants must be symptomatic with a Myelofibrosis Symptom Assessment Form (MFSAF) version (v) 4.0 Total Symptom Score of >= 10 at screening, and be anemic with hemoglobin (Hgb) < 10 gram/deciliter (g/dL). For participants with ongoing JAKi therapy at screening, JAKi therapy must be tapered over a period of at least 1 week, followed by a 2-week non-treatment washout interval prior to randomization. Participants will be randomized 2:1 to orally self-administer blinded treatment: MMB plus placebo or DAN plus placebo. Participants randomized to receive MMB who complete the randomized treatment period to the end of Week 24 may continue to receive MMB in the open-label extended treatment period to the end of Week 204 (a total period of treatment of approximately 4 years) if the participants tolerates and continues to benefit from MMB. Participants randomized to receive DAN may cross-over to MMB open-label treatment in the following circumstances: at the end of Week 24 if they complete the randomized treatment period; or at the end of Week 24 if they discontinue treatment with DAN but continue study assessments and do not receive prohibited medications including alternative active anti-MF therapy; or at any time during the randomized treatment period if they meet the protocol-defined criteria for radiographically confirmed symptomatic splenic progression. Participants randomized to receive DAN who are receiving clinical benefit at the end of Week 24 may choose to continue DAN therapy up to Week 48. The comparator treatment, DAN, is an approved medication in the US and in some other countries and is recommended by national guidelines as a treatment for anemia in MF.
Increased levels of TGF-β1 were detected in serum, plasma and BM and positively correlated with both grade of BMF and extent of leukemic cell infiltration in the marrow. TGF-β likely plays a dual role in promoting myelofibrosis and myeloproliferation, both of which are the bone marrow morphologic hallmark of MF. AVID200 is a drug that targets TGF-β1 and TGF-β3. The study team hypothesizes that inhibiting the TGF-β signaling pathway in MF will decrease the fibrogenic stimuli leading to myelofibrosis and concomitantly interrupt myeloproliferation and restore normal hematopoiesis. This is a first in human, open-label, multicenter, Phase I/Ib trial of AVID200. Patients must have intermediate-2 or higher primary myelofibrosis (PMF), post-essential thrombocythemia or polycythemia-vera related MF (Post ET/PV MF). This study will enroll up to 24 patients. AVID200 is delivered by IV infusion on day 1 of each 3 week cycle.
This was an open-label, multi-center, randomized phase 2 study. This is a two-stage design.In the first stage, two dose groups were set up, the 100 mg bid dose group and the 200 mg qd dose group, which were randomized at 1:1, with 50 subjects in each group, and a total of 100 cases in the two groups. In the second stage, approximately 36 subjects were added to the randomized group.
This is Single-Arm, Open-Label Efficacy and Safety Trial of Fedratinib in Subjects with DIPSS (Dynamic International Prognostic Scoring System)-Intermediate or High- Risk Primary Myelofibrosis (PMF), Post-Polycythemia Vera Myelofibrosis (post-PV MF), or Post-Essential Thrombocythemia Myelofibrosis (post-ET MF) and Previously Treated with Ruxolitinib. The primary objective of the study is to evaluate the percentage of subjects with at least a 35% reduction in spleen size and one of the secondary objectives is to evaluate the safety of fedratinib.
