A Phase II Study of Luspatercept Plus Darbepoetin Alfa in Non-mutated SF3B1 Lower-risk Myelodysplastic Syndromes
Summary: This is a single arm open-label Phase II trial of luspatercept and darbepoetin alfa in non-mutated SF3B1 , lower-risk, RBC transfusion dependent MDS participants with an endogenous erythropoietin (EPO) level \< 500 IU/L.
A Phase 2 Open-label Study to Evaluate Momelotinib in Combination With Luspatercept in Participants With Transfusion Dependent Primary or Secondary Myelofibrosis
Summary: The purpose of this Phase 2 study is to evaluate the efficacy and safety of momelotinib (MMB) in combination with luspatercept (LUSPA) in participants with transfusion dependence (TD) primary myelofibrosis (PMF) or Post-polycythemia vera (PV)/ essential thrombocythemia (ET) myelofibrosis (MF) who are either janus kinase (JAK) inhibitor (JAKi) naïve or experienced.
A Phase 2, Single Arm Study of Luspatercept for the Treatment of Anemia in Lower Risk Myelodysplastic Syndromes (MDS) or Non-Proliferative Myelodysplastic Syndromes/ Myeloproliferative Neoplasms (MDS/MPN)
Summary: The purpose of the study is to see if participants with anemia due to their type of MDS or MDS/MPN will experience a more decreased need for regular blood transfusions if they take luspatercept plus best supportive care, and what effect, good and/or bad, luspatercept has on them and their anemia due to MDS or MDS/MPN. The safety and tolerability of luspatercept will also be evaluated in this study...
A Randomized Phase I/ II Multicenter Study Evaluating Combination of Luspatercept in LR-MDS Without RS Having Failed or Being Ineligible to ESA
Summary: Study of the combination of luspatercept in low-risk myelodysplastic syndrom (LR-MDS) without ring sideroblasts (RS) having failed or being ineligible to ESA
A Phase 3, Open-label, Randomized Study to Compare the Efficacy and Safety of Luspatercept (ACE-536) vs Epoetin Alfa for the Treatment of Anemia Due to Revised International Prognostic Scoring System (IPSS-R) Very Low, Low, or Intermediate-Risk Myelodysplastic Syndrome (MDS) in Erythropoiesis-Stimulating Agent (ESA)-Naive Participants Who Are Non-Transfusion Dependent (NTD): The ELEMENT-MDS Trial
Summary: The purpose of the study is to compare the efficacy and safety of Luspatercept vs epoetin alfa in the treatment of anemia in adults due to IPSS-R very low, low, intermediate-risk MDS in ESA-naïve participants who are non-transfusion dependent (NTD).
A Phase 3b, Open-label, Single-arm, Rollover Study to Evaluate Long-term Safety in Subjects Who Have Participated in Other Luspatercept (ACE-536) Clinical Trials
Summary: A Phase 3b, open-label, single-arm, rollover study to evaluate the long-term safety of luspatercept, to the following participants: * Participants receiving luspatercept on a parent protocol at the time of their transition to the rollover study, who tolerate the protocol-prescribed regimen in the parent trial and, in the opinion of the investigator, may derive clinical benefit from continuing trea...
A Pilot, Open-Label Study of Luspatercept for Patients With Lower Risk Myelodysplastic Syndromes (MDS)
Summary: To learn if luspatercept is more effective in helping to reduce the number of blood transfusions needed by patients with LR-MDS.
A Phase 2a Study to Evaluate the Safety and Pharmacokinetics of Luspatercept (ACE-536) in Pediatric Participants With Beta (β)-Thalassemia
Summary: This is a Phase 2a study to evaluate the safety and pharmacokinetics (PK) of luspatercept in pediatric participants with β-thalassemia. The study will be conducted in 2 parts for both transfusion-dependent (TD) and non-transfusion-dependent (NTD) β-thalassemia participants: TD Part A will be in adolescent participants aged 12 to \<18 years with two dose escalation cohorts, followed by a dose expan...
A Phase 2, Study for the Treatment of Anemia With Alpha (α)-Thalassemia to Determine the Efficacy and Safety of Luspatercept (BMS-986346/ACE-536) in Adults and Evaluate the Safety and Pharmacokinetics in Adolescents
Summary: The purpose of the study is to evaluate the efficacy and safety of luspatercept plus best supportive care (BSC) vs placebo plus BSC on anemia in adult participants with α-thalassemia hemoglobin H (HbH) disease and determine the safety and drug levels in adolescent participants.
Phase I Study With Dose-escalation and Expansion Evaluating the Safety and Efficacy of Oral Arsenic (ATO) in Low-risk Myelodysplastic Syndromes Failing Erythropoiesis Stimulating Agents and Luspatercept (or Ineligible for the Latter)
Summary: Phase I study with dose-escalation and expansion evaluating the safety and efficacy of oral Arsenic (ATO) in low-risk Myelodysplastic Syndromes having failed to Erythropoiesis Stimulating Agents and Luspatercept (or ineligible for the latter).
Efficacy of Luspatercept In Clonal Cytopenias of Uncertain Significance
Summary: The purpose of this clinical trial is to test how well the drug luspatercept works in improving low blood cell counts in people with clonal cytopenias of uncertain significance (CCUS). The main questions the study seeks to answer include: * How many patients experience improvements in their low blood counts (red cells, platelets, or white cells) within 24 weeks, based on specific criteria for bloo...
Efficacy and Safety of Luspatercept for the Treatment of Anemia Due to Myelodysplastic Syndromes With del5q, Refractory/Resistant/Intolerant to Prior Treatments, Who Require Red Blood Cell Transfusions
Summary: Myelodysplastic syndromes, primarily affecting older adults, are a heterogeneous group of clonal disorders of hematopoietic stem cells characterized by ineffective hematopoiesis that manifest clinically as anemia, neutropenia, and/or thrombocytopenia of variable severity; these often result in RBC- transfusion dependent (TD) anemia, increased risk of infection, and/or hemorrhage, as well as a pote...
