Filter by: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.
This multi-center, multi-arm trial is evaluating the safety and efficacy of tagraxofusp, a CD123-targeted therapy, in patients with either chronic myelomonocytic leukemia (CMML) or myelofibrosis (MF). There are two CMML cohorts, one enrolling patients with CMML (CMML-1 or CMML-2) who are refractory/resistant or intolerant to hypomethylating agents (HMA), hydroxyurea (HU), or intensive chemotherapy; and one enrolling treatment-naive patients with CMML (CMML-1 or CMML-2) with molecular features associated with poor prognosis. The MF cohort will enroll patients who are resistant/refractory or intolerant to approved JAK therapy (JAK1/JAK2 or JAK2).
The goal of this clinical research study is to learn if pracinostat, when given in combination with ruxolitinib, can help to control myelofibrosis (MF). The safety of this drug combination will also be studied. This is an investigational study. Pracinostat is not FDA-approved or commercially available. It is currently being used for research purposes only. Ruxolitinib is FDA-approved and commercially available to treat MF. The study doctor can explain how the study drugs are designed to work. Up to 25 participants will be enrolled in this study. All will take part at MD Anderson.
The purpose of this study is to determine whether stem cells collected from a donor's blood stream will be as safe and effective as using bone marrow collected from a donor's pelvic bone.
This phase I/Ib trial studies the side effects and best dose of azacitidine and sonidegib or decitabine and so see how well they work in treating patients with myeloid malignancies. The hedgehog (Hh) signaling pathway plays an important role in cellular growth, differentiation and repair. Inappropriate activation of Hh pathway signaling and uncontrolled cellular proliferation may be associated with mutations in the Hh-ligand cell surface receptor Smo. Sonidegib binds to the Hh cell surface receptor Smo, which may result in the suppression of the Hh signaling pathway and the inhibition of cancer cells. Azacitidine and decitabine may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving azacitidine together with sonidegib or decitabine may be a safe and successful treatment for patients with myeloid malignancies.
This open-label study is to determine the long-term safety and tolerability of momelotinib in previously enrolled study participants with primary myelofibrosis (PMF), post-polycythemia vera myelofibrosis (post-PV MF), post-essential thrombocythemia myelofibrosis (post-ET MF), polycythemia vera (PV), or essential thrombocythemia (ET), who have tolerated and achieved stable disease or better with momelotinib treatment while enrolled in a previous clinical trial.
This study is to determine the efficacy of momelotinib (MMB) versus best available therapy (BAT) in anemic or thrombocytopenic adults with primary myelofibrosis (PMF), or post-polycythemia vera or post-essential thrombocythemia myelofibrosis (Post-PV/ET MF) who were treated with ruxolitinib as measured by splenic response rate at Week 24 (SRR24). Participants will be randomized to receive either MMB or BAT for 24 weeks during the randomized treatment phase, after which they will be eligible to receive MMB in an extended treatment phase for up to an additional 204 weeks. After discontinuation of study medication, assessments will continue for 12 additional weeks, after which participants will be contacted for survival follow-up approximately every 6 months for up to 5 years from the date of enrollment or until study termination. For those subjects planning to continue treatment with MMB following the end of the study, the End of Treatment, 30-day, 12-Week, and survival follow-up visits are not required.
This phase II trial studies how well second mitochondrial-derived activator of caspases (SMAC) mimetic LCL161 (LCL161) works in treating patients with primary myelofibrosis, post-polycythemia vera myelofibrosis, or post-essential thrombocytosis myelofibrosis. SMAC mimetic LCL161 may help control the growth of abnormal cells by promoting apoptosis (programmed cell death).
This is an open-label, multicenter clinical study in order to collect and examine data concerning the safety and efficacy of ruxolitinib in patients with Primary Myelofibrosis (MF), Post-Polycythemia Vera (PV) MF, Post-Essential Thrombocythemia (ET) MF.
The main purpose of this study is to assess the effects of cyclophosphamide (cytoxan) in the post transplant setting to prevent onset of acute graft-versus-host disease (GVHD). The primary objective is to determine the incidence of grade II-IV acute GVHD following Allogeneic (allo) Hematopoeitic Cell Transplant (HCT) using post-transplant cyclophosphamide (cytoxan) for patients with human leukocyte antigen (HLA) matched unrelated (MUD) and mismatched unrelated (MMUD) donors. Other objectives for this study will be the determination of disease-free survival (DFS) and overall survival (OS) following allo HCT and assess the safety of post-transplant cyclophosphamide (cytoxan) for MUD and MMUD transplantation. Disease recurrence and time to recurrence in patients receiving post-transplant cyclophosphamide compared to historical control without post-transplant cyclophosphamide (cytoxan) will also be evaluated. Other objectives will be to determine the time of onset, severity, responsiveness to treatment, organs involved of acute and chronic GVHD as well as observation of Immune Reconstitution over time.
