Active clinical trials for "Primary Myelofibrosis"

This clinical trial evaluates the safety and effectiveness of adding itacitinib to cyclophosphamide and tacrolimus for the prevention of graft versus host disease (GVHD) in patients undergoing hematopoietic stem cell transplant. Itacitinib is an enzyme inhibitor that may regulate the development, proliferation, and activation of immune cells important for GVHD development. Cyclophosphamide and tacrolimus are immunosuppressive agents that may prevent GVHD in patients who receive stem cell transplants. Giving itacitinib in addition to cyclophosphamide and tacrolimus may be more effective at preventing GVHD in patients receiving hematopoietic stem cell transplants.

Prospective study to evaluate the relevance of CALR allele burden monitoring as a molecular marker of disease progression.

The study is being done to see if the combination of ruxolitinib and abemaciclib is a safe and effective treatment for people with primary or post-polycythemia vera/essential thrombocythemia myelofibrosis.

This pilot phase II trial studies P1101 (polyethyleneglycol [PEG]-proline-interferon alpha-2b) in treating patients with myelofibrosis. PEG-proline-interferon alpha-2b is a substance that can improve the body's natural response and may slow the growth of myelofibrosis.

This is Single-Arm, Open-Label Efficacy and Safety Trial of Fedratinib 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 a 35% reduction in spleen size and one of the secondary objectives is to evaluate the safety of fedratinib.

MOMENTUM is a randomized, double-blind, active control Phase 3 trial intended to confirm the differentiated clinical benefits of the investigational drug momelotinib (MMB) versus danazol (DAN) in symptomatic and anemic subjects who have previously received an approved Janus kinase inhibitor (JAKi) therapy for myelofibrosis (MF). The purpose of this clinical study is to compare the effectiveness and safety of MMB to DAN in treating and reducing: 1) disease related symptoms, 2) the need for blood transfusions and 3) splenomegaly, in adults with primary MF, post-polycythemia vera MF or post-essential thrombocythemia MF. The study is planned in countries including, but not limited to: Australia, Austria, Belgium, Bulgaria, Canada, Czech Republic, Denmark, France, Germany, Hungary, Israel, Italy, New Zealand, Poland, Romania, Singapore, South Korea, Spain, Sweden, Taiwan, UK, and US. Subjects must be symptomatic with a MFSAF v4.0 Total Symptom Score of ≥ 10 at screening, and be anemic with Hgb < 10 g/dL. For subjects with ongoing JAKi therapy at screening, JAKi therapy must be tapered over a period of at least 1 week, followed by a 2-week non-treatment washout interval prior to randomization. Subjects will be randomized 2:1 to orally self-administer blinded treatment: MMB plus placebo or DAN plus placebo. Subjects randomized to receive MMB who complete the randomized treatment period to the end of Week 24 may continue to receive MMB in the open-label extended treatment period to the end of Week 204 (a total period of treatment of approximately 4 years) if the subject tolerates and continues to benefit from MMB. Subjects randomized to receive DAN may cross-over to MMB open-label treatment in the following circumstances: at the end of Week 24 if they complete the randomized treatment period; or at the end of Week 24 if they discontinue treatment with DAN but continue study assessments and do not receive prohibited medications including alternative active anti-MF therapy; or at any time during the randomized treatment period if they meet the protocol-defined criteria for radiographically-confirmed symptomatic splenic progression. Subjects randomized to receive DAN who are receiving clinical benefit at the end of Week 24 may choose to continue DAN therapy up to Week 48. The comparator treatment, DAN, is an approved medication in the US and in some other countries and is recommended by national guidelines as a treatment for anemia in MF.

Myelofibrosis (MF) is a bone marrow illness that affects blood-forming tissues in the body. MF disturbs the body's normal production of blood cells, causing extensive scarring in the bone marrow. This leads to severe anemia, weakness, fatigue, and an enlarged spleen. The purpose of this study is to see how safe and tolerable ABBV-744 is, when given alone, and in combination with ruxolitinib or navitoclax, for adult participants with MF. ABBV-744 is an investigational drug being developed for the treatment of MF. The study has 4 segments - A, B, C, and D. In Segment A, the safe dosing regimen of ABBV-744 is identified and then, given alone as monotherapy. In Segment B, C, and D, combination therapies of ABBV-744 with either ruxolitinib or navitoclax are given. Adult participants with a diagnosis of MF will be enrolled. Around 130 participants will be enrolled in 60 sites worldwide. In Segment A, participants will receive different doses and schedules of oral ABBV-744 tablet to identify safe dosing regimen. Additional participants will be enrolled at the identified monotherapy dosign regimen. In Segment B, participants will receive oral ruxolitinib and ABBV-744 will be given as "add-on" therapy. In Segment C, participants will receive ABBV-744 and oral navitoclax. In Segment D, participants will receive ABBV-744 and ruxolitinib. Participants will receive treatment until disease progression or the participants are not able to tolerate the study drugs. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of treatment will be checked by medical assessments, blood and bone marrow tests, checking for side effects, and completing questionnaires.

This is a Phase 2 open-label, multicenter study evaluating tolerability and efficacy of navitoclax alone or when added to ruxolitinib in participants with myelofibrosis.

This pilot clinical trial studies the side effects and best dose of ruxolitinib phosphate when given together with chemotherapy before and after a donor stem cell transplant in treating patients with myelofibrosis. Ruxolitinib phosphate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as fludarabine phosphate and melphalan, 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. Giving ruxolitinib phosphate together with chemotherapy before and after a donor stem cell transplant may help stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. The donated stem cells may also replace the patient?s immune cells and help destroy any remaining cancer cells.

Myelofibrosis is a type of bone marrow cancer that usually develops slowly and disrupts body's normal production of blood cells. It causes bone marrow scarring, leading to severe anemia that can cause weakness and fatigue. It can also cause a low number of blood-clotting cells called platelets, which increases risk of bleeding. Myelofibrosis often causes an enlarged spleen. The purpose of this study is to see if a combination of navitoclax and ruxolitinib is more effective and safe in assessment of change in spleen volume when compared to ruxolitinib in participants with myelofibrosis. Navitoclax is an investigational drug for the treatment of myelofibrosis. Participants in this study are divided into two groups, called treatment arms. Each group receives a different treatment. Adult participants with a diagnosis of myelofibrosis will be enrolled. Around 230 participants will be enrolled in approximately 190 sites worldwide. Participants will receive oral navitoclax tablet with oral ruxolitinib tablet or oral ruxolitinib tablet with oral placebo (no active drug) tablet and treatment may continue untill the participant cannot tolerate the study drug, or benefit is not achieved, or other reasons which qualify for discontinuation of the study drug. There may be a higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the course of the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, magnetic resonance imaging (MRI) or computed tomography (CT) scan, bone marrow tests, checking for side effects, and completing questionnaires.
