Luspatercept is under clinical development by Merck & Co and currently in the Phase II and Phase III in clinical pathway. The characteristics of the clinical trial as well as other attributes related to the drug, regulations, and company play a fundamental role in ensuring the likelihood of transition that the drug moves from its current development stage to next.
According to GlobalData, the latest event to affect Luspatercept’s likelihood of approval (LoA) and phase transition for Post-Essential Thrombocythemia Myelofibrosis (Post-ET MF) took place on 19 Oct 2022, which increased the likelihood that the drug progresses to the next phase in its clinical pathway and increased the likelihood of final approval for this indication.
In addition, the same event on 19 Oct 2022 increased Luspatercept’s LoA and decreased Phase Transition Success Rate (PTSR) for Myelofibrosis, and increased LoA and PTSR for Post-Polycythemia Vera Myelofibrosis (PPV-MF).
GlobalData uses proprietary data and analytics to provide a complete picture of this assessment in their Luspatercept Likelihood of Approval (LoA) and Phase Transition Success Rate (PTSR) Report.
Luspatercept-AMT (Reblozyl) is a recombinant fusion protein, it is produced in chinese hamster ovary cells by recombinant DNA technology, acts as an erythroid maturation agent. It is formulated as lyophilized powder for solution for subcutaneous route of administration. Reblozyl is indicated for the treatment of anemia in adult patients with beta thalassemia who require regular red blood cell (RBC) transfusions,and for the treatment of adult patients with transfusion-dependent anemia due to very low-, low- and intermediate-risk myelodysplastic syndromes (MDS) with ring sideroblasts, who had an unsatisfactory response or are ineligible for erythropoietin-based therapy, and adult patients with transfusion-dependent anemia associated with beta thalassemia.
Luspatercept (ACE-536) is under development for the treatment of anemia due to myelodysplastic syndrome, non-transfusion dependent (NTD) beta thalassemia, alpha-thalassemia, beta-thalassemia, anemia in myelofibrosis, post polycythemia vera myelofibrosis, post essential thrombocythemia myelofibrosis. The drug candidate is a recombinant fusion protein administered subcutaneously as a solution. Luspatercept is a modified activin receptor type IIB fusion protein. It is a GDF11 and GDF-8 inhibitor.
