Active clinical trials for "Polycythemia Vera"

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.

This is a Phase 1, open-label, study of TGR-1202, a PI3K delta inhibitor, administered together with ruxolitinib in patients with myeloproliferative neoplasms (specifically: polycythemia vera, primary myelofibrosis, PPV-MF or PET-MF) and MDS/MPN.

This phase I/II trial studies the best dose of venetoclax when given together with azacitidine and pevonedistat and to see how well it works in treating patients with newly diagnosed acute myeloid leukemia. 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. Pevonedistat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving azacitidine, venetoclax, and pevonedistat may work better in treating patients with acute myeloid leukemia.

A Phase 3, multicenter, open-label, randomized study to evaluate the efficacy and safety of fedratinib compared to best available therapy (BAT) 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 35% spleen volume reduction in the fedratinib and the BAT arms.

The purpose of the study is to compare the efficacy and safety of parsaclisib when combined with ruxolitinb versus placebo combined with ruxolitinib in participants with myelofibrosis who have suboptimal response while receiving ruxolitinib monotherapy.

This is an open label, single arm trial of PTG-300 in subjects with PV who are newly diagnosed or for whom current therapy is not sufficient to control their hematocrit and have hematocrit >48% prior to dosing. The PTG-300 dose and schedule may be adjusted every 2 to 4 weeks to maintain hematocrit <45% with a target of <43%. Subjects may receive PTG-300 treatment for up to 52 weeks.

The purpose of the study is to compare the efficacy of parsaclisib when combined with ruxolitinb versus placebo combined with ruxolitinib in participants with myelofibrosis.

This study is a phase II single-arm study designed to evaluate the efficacy and safety of P1101 in Chinese PV patients who are intolerance or resistance to HU.

The primary objective of this study is to provide extended access and assess long-term safety of momelotinib (MMB) in participants with primary myelofibrosis (PMF) or post-polycythemia vera or post-essential thrombocythemia myelofibrosis (Post-PV/ET MF) enrolled in studies GS-US-352-0101 (NCT01969838), GS-US-352-1214 (NCT02101268), GS-US-352-1154 (NCT02124746), SRA-MMB-301 who are currently receiving treatment with MMB (available as 50mg,100 mg, 150 mg and 200 mg tablets) and have not experienced progression of disease. The secondary objective is to assess overall survival (OS) and leukemia free survival (LFS) in all subjects.

This phase II trial studies how well topotecan hydrochloride and carboplatin with or without veliparib work in treating patients with myeloproliferative disorders that have spread to other places in the body and usually cannot be cured or controlled with treatment (advanced), and acute myeloid leukemia or chronic myelomonocytic leukemia. Drugs used in chemotherapy, such as topotecan hydrochloride and carboplatin, 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. Veliparib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving topotecan hydrochloride, carboplatin, and veliparib may work better in treating patients with myeloproliferative disorders and acute myeloid leukemia or chronic myelomonocytic leukemia compared to topotecan hydrochloride and carboplatin alone.
