Active clinical trials for "Thrombocythemia, Essential"

Primary Objective: Dose Ranging Phase: To evaluate the efficacy of daily oral doses of 100, 200, and 400 mg SAR302503 in patients with PV and ET who are resistant or intolerant to hydroxyurea (per European LeukemiaNet criteria) for : Inducing absence of phlebotomy and a hematocrit below 45% for a minimum of 3 months in patients with polycythemia vera, and Reduction of platelet count to ≤400 x 10x9/L for a minimum of 3 months in patients with essential thrombocythemia. PV Dose Expansion Phase and ET Dose Ranging Phase (only 600 mg dose group): To evaluate the efficacy of daily oral SAR302503 in patients with PV and ET who are resistant or intolerant to hydroxyurea (per European LeukemiaNet criteria) for: Inducing absence of phlebotomy eligibility beginning at Day 1 of Cycle 4 visit and continuing through Day 1 of Cycle 6 visit in patients with PV, and Reduction of platelet count to ≤400 x 10x9/L beginning at Day 1 of Cycle 4 visit and continuing through Day 1 of Cycle 6 visit in patients with ET. Secondary Objectives: To evaluate the safety of SAR302503. To evaluate the efficacy of SAR302503 in patients with PV who are resistant or intolerant to hydroxyurea for inducing absence of phlebotomy eligibility. To evaluate the efficacy of SAR302503 in patients with ET who are resistant or intolerant to hydroxyurea for reduction of platelet counts. To evaluate the efficacy of SAR302503 in inducing complete and partial responses beginning at Day 1 of Cycle 6 visit through Cycle 8. To evaluate splenic response as measured by spleen volume using MRI or CT. To evaluate the pharmacokinetics of SAR302503 after single and repeat doses. To evaluate the pharmacodynamics of SAR302503 as measured by changes in JAK2V617F allele burden in patients with JAK2V617F mutation, and STAT3 phosphorylation inhibition. To measure improvement in baseline myeloproliferative neoplasm (MPN)-associated symptoms, as well as overall impact on quality of life. To measure generic health-related quality of life and utility value using the EuroQol Group (EQ-5DTM) questionnaire.

This phase II trial is studying how well giving lenalidomide together with prednisone works in treating patients with myelofibrosis. Lenalidomide may stop the growth of myelofibrosis by blocking blood flow to the cancer. It may also stimulate the immune system in different ways and stop cancer cells from growing. Drugs used in chemotherapy, such as prednisone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving lenalidomide together with prednisone may kill more cancer cells.

The purpose of this trial is to see if Hydroxyurea + aspirin is a better treatment than aspirin alone for Intermediate Risk Primary Thrombocythemia (PT) patients.

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.

The purpose of this study is to test the effectiveness of a drug called pembrolizumab in patients with Myeloproliferative Neoplasm (MPN); chronic phase (MF-CP), accelerated phase (MPN-AP), or blast phase (MF-BP). Myelofibrosis neoplasm (MPN) is a group of diseases of the bone marrow in which excessive cells are produced. Pembrolizumab also known as Keytruda is a drug that has recently been approved in the United Stated by the Food and Drug Administration (FDA) for the treatment of patients with unresectable or metastatic melanoma and disease progression. Pembrolizumab is experimental in the treatment of MPN. The researchers want to find out what effects, good and /or bad it has on participants and the disease. Participants qualify to take part in this research study if have been diagnosed with a MPN blood disorder called myelofibrosis (MF). Accelerated (10-19% blasts in the blood or bone marrow) and blast phase (>20% blasts in the blood or bone marrow) MPN has been a difficult disease to treat. The term "blasts" refers to immature cells found in the bone marrow. They are not fully developed, and therefore, do not yet carry out any particular function within the body. Funds for conducting this research are provided by Merck and Company, the manufacturer of the study drug pembrolizumab.

This study is to evaluate the efficacy and safety according to incremental dosing for 8 weeks and duration of administration for 1 year in patients with high-risk essential thrombocythemia.

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.

To see if it is possible to use short-duration tacrolimus after a peripheral blood stem cell transplant in certain malignancies that are considered difficult to engraft.

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.

The purpose of this study is to determine the safety and tolerability of orally administered NS-018 in patients with Primary Myelofibrosis (PMF), Post-polycythemia Vera Myelofibrosis (post-PV MF), or Post-essential Thrombocythemia Myelofibrosis (post-ET MF)
