Active clinical trials for "Primary Myelofibrosis"

The aim of this phase II study is to test a novel concept in the treatment of patients with myeloproliferative neoplasms (MPN), a disease of the bone marrow. With no current cure available, MPN are a group of chronic leukemias (blood cancers) in which patients produce too many blood cells. These increased blood cell numbers cause problems to the patient such as bleedings or thrombosis and some patients may progress to acute leukemia, a life threatening condition. Most MPN patients have a gene mutation called JAK2-V617F. The disease is maintained by mutant MPN stem cells that reside in the bone marrow in specialized locations called "niches". These niches need connections to the nervous system. New findings show that these connections are destroyed by the presence of the mutated MPN stem cells. Research teams found that some drugs (beta3-sympathicomimetics) can restore these damaged niches and at the same time reduce the MPN disease manifestation in a mouse model of MPN. Such sympathicomimetic drugs are already being used to treat patients with asthma or hyperactive bladder. These drugs have shown to have only few side effects. The study tests the effects of the beta-3-sympathicomimetic drug Mirabegron (Betmiga®) on MPN disease in 39 patients that carry a JAK2-V617F mutation. The hypothesis is that Mirabegron will have a beneficial effect on bone marrow niche cells and will thereby improve the disease manifestation in MPN patients. This study should provide a rapid answer whether targeting the nervous system of the niche cells could be useful for patients with MPN and warrants to be tested in larger and more long-term studies.

A number of groups have demonstrated very low incidence of acute and chronic graft-versus-host disease (GVHD) with post-transplantation cyclophosphamide (PTCy) in haploidentical and unrelated allogeneic stem cell transplantation (SCT). Still the relapse of the underlining malignancy is a problem after this prophylaxis. Ruxolitinib is currently one of the most promising drugs in the treatment of steroid-refractory GVHD. On the other hand, its primary indication is myelofibrosis, and it was demonstrated that ruxolitinib before allogeneic SCT might improve the outcome. This pilot trial evaluates whether the combination of PTCy and ruxolitinib facilitates adequate GVHD control, and decreases the risk of graft failure and disease progression in myelofibrosis patients.

Primary Objective: - To evaluate the efficacy of daily oral doses of 300 mg, 400 mg, and 500 mg SAR302503 and combined for the response rate defined with the ≥35% reduction of spleen volume as determined by magnetic resonance imaging (MRI or computed tomography scan [CT] in patients with contraindications for MRI). Secondary Objectives: To evaluate the safety of SAR302503 for both pooled (300, 400, and 500mg) and individual doses population. To evaluate the pharmacokinetics (PK) of SAR302503 after single and repeat-dose. To evaluate the effect on Myelofibrosis (MF)-associated symptoms (Key MF symptoms) as measured by the modified Myelofibrosis Symptom Assessment Form (MFSAF). To evaluate the durability of splenic response. To evaluate the effect of SAR302503 on bone marrow with regard to changes on reticulin fibrosis.

Primary Objective: - To evaluate the efficacy of once daily dose of SAR302503 in subjects previously treated with ruxolitinib and with a current diagnosis of intermediate-1 with symptoms, Intermediate-2 or high-risk primary myelofibrosis (PMF), post-polycythemia vera myelofibrosis (Post-PV MF), or post-essential thrombocythemia myelofibrosis (Post-ET MF) based on the reduction of spleen volume at the end of 6 treatment cycles; Secondary Objectives: To evaluate the effect of SAR302503 on Myelofibrosis (MF) associated symptoms as measured by the modified Myelofibrosis Symptom Assessment Form (MFSAF) diary To evaluate the durability of splenic response To evaluate the splenic response to SAR302503 by palpation at the end of Cycle 6 To evaluate the splenic response to SAR302503 at the end of Cycle 3 To evaluate the effect of SAR302503 on the Janus kinase 2 (JAK2) V617F allele burden To evaluate the safety and tolerability of SAR302503 in this population To evaluate plasma concentrations of SAR302503 for population PK analysis, if warranted

This phase I trial is studying the side effects and best dose of vorinostat when given together with cytarabine and etoposide in treating patients with relapsed or refractory acute leukemia or myelodysplastic syndromes or myeloproliferative disorders. Vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cytarabine and etoposide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving vorinostat together with cytarabine and etoposide may kill more cancer cells.

This phase I trial is studying the side effects and best dose of belinostat when given together with azacitidine in treating patients with advanced hematologic cancers or other diseases. Belinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer. Drugs used in chemotherapy, such as azacitidine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving belinostat together with azacitidine may kill more cancer cells.

This is an open-label, non-randomized, multi-center trial designed to provide expanded access of deferasirox to patients with congenital disorders of red blood cells and chronic iron overload from blood transfusions who cannot adequately be treated with locally approved iron chelators.

This clinical trial studies the side effects and best dose of giving fludarabine and total-body irradiation (TBI) together followed by a donor stem cell transplant and cyclosporine and mycophenolate mofetil in treating human immunodeficiency virus (HIV)-positive patients with or without cancer. Giving low doses of chemotherapy, such as fludarabine, and TBI before a donor bone marrow or peripheral blood stem cell transplant helps stop the growth of cancer or abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine (CSP) and mycophenolate mofetil (MMF) after the transplant may stop this from happening.

Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Phase I trial to study the effectiveness of imatinib mesylate in treating patients who have advanced cancer and liver dysfunction

The goal of this clinical research study is to find the highest safe dose of RAD001 that can be given as a treatment for leukemia, mantle cell lymphoma, or myelofibrosis. Another goal is to learn how effective the dose that is found is as a treatment.
