NCT07445893
The goal of this clinical trial is to evaluate the efficacy and safety of Gecacitinib in combination with pegylated interferon for the treatment of polycythemia vera (PV).The main question it aims to answer is: Can PV patients achieve hematological remission after receiving the combination therapy? Participants will: Receive combination treatment with Gecacitinib Hydrochloride Tablets and pegylated interferon for 24 weeks Visit the hospital regularly for examinations and follow-up assessments
NCT06541249
Low-dose MTX is a widely used, inexpensive, and safe therapy used for decades and is well tolerated by patients with rheumatologic diseases. Recently, it was identified as a type 2 JAK inhibitor. If MTX proves to be safe and tolerable with a signal of clinical activity, this could have a significant benefit to patients with MPNs. Beyond the potential benefit of adding a type 2 JAK inhibitor to current therapy, this could signal the need to study MTX in MPNs further as a monotherapy. Discovering MTX as safe and clinically effective in MPNs could be profound on both a public health and global health scale for patients who are uninsured and cannot afford more expensive novel JAK inhibitors, or for those in countries where JAK inhibitors are not available. Accordingly, the research team deems it reasonable and prudent to assess the safety and efficacy of MTX in addition to current therapy for patients with MPN. The research team will evaluate patients for spleen responses, symptom responses, and cytologic responses. Correlative data will evaluate pharmacokinetic and disease modifying activity of MTX in MPNs to inform future clinical trials.

NCT02577926
The Philadelphia chromosome negative myeloproliferative neoplasms (MPN) comprise a group of clonal hematological malignancies that are characterized by chronic myeloproliferation, splenomegaly, different degrees of bone marrow fibrosis, and disease-related symptoms including pruritus, night sweats, fever, weight loss, cachexia, and diarrhea. In addition, due to elevated numbers of leucocytes, erythrocytes and/or platelets, the disease course can be complicated by thromboembolic disease, hemorrhage, and leukemic transformation as well as myelofibrosis. Patients with polycythemia vera (PV) typically harbor an increased number of blood cells from all three hematopoietic cell lineages due to clonal amplification of hematopoetic stem cells, while patients with essential thrombocythemia (ET) typically show a predominant expansion of the megakaryocytic lineage. Most patients with PV below the age of 60 years are currently being treated with acetylsalicylic acid +/- phlebotomy only, and patients with low-risk ET have an almost normal life expectancy and often do not require specific treatment. However, PV- as well as ET-patients with a higher risk for complications require cytoreductive treatment. In addition, constitutional symptoms can be unbearable to patients even in the absence of bona fide high risk factors, and these patients may similarly benefit from antineoplastic therapy.
NCT06798805
In this study the aim is to investigate the pathogenetic role of extracellular vesicles and senescence in Myeloproliferative Neoplasms. In particular, the goal of this project is to identify possible EV-based biomarkers of senescence according to gender, which are disease-specific, biology-related, and predictive of short-term outcome in terms of Event-Free Survival and to define personalized targets for new therapeutic approaches.
NCT04243122
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.
NCT01392443
The objective of this study was to determine the efficacy of INC424 as assessed by reduction in spleen volume in patients with primary myelofibrosis (MF), post-polycythemia vera (PV) MF, or post-essential thrombocythemia (ET) MF. The safety and tolerability of INC424 and the effects of INC424 on patient reported outcomes and the duration of response as assessed by reduction in spleen volume was also assessed.
