Clinical Trial Summary

The purpose of this Phase 3 study is to evaluate the efficacy and safety of Luspatercept compared with placebo in subjects with myeloproliferative neoplasm (MPN)-associated Myelofibrosis (MF) and anemia on concomitant Janus kinase 2 (JAK2) inhibitor therapy and who require red blood cell count (RBC) transfusions. The study is divided into Screening Period, a Treatment Phase (consisting of a Blinded Core Treatment Period, a Day 169 Response Assessment, a Blinded Extension Treatment Period, and an Open-label Extension Treatment Period), and a Posttreatment Follow-up Period. Following the Day 169 Response Assessment, subjects who did not show clinical benefit will have the option to unblind. Subjects who were on placebo during the Blinded Core Treatment Period will have the opportunity to crossover into the Open-Label Extension Treatment Period and receive Luspatercept.

Description:

Permitted Concomitant Medications and Procedures - Subjects are receiving a JAK2 inhibitor for the treatment of MPN-associated MF that is approved in the country where the study is being conducted. JAK2 inhibitors are to be used according to their respective label and as prescribed as part of the subject's standard-of-care therapy as prescribed by their physician prior to study entry. - Best supportive care (BSC) includes, but is not limited to, treatment with transfusions (eg, RBC, platelet, whole blood), ICTs, antibiotic, antiviral and/or antifungal therapy, and nutritional support as needed. - Granulocyte colony-stimulating factors (ie, G-CSF, granulocyte macrophage colony-stimulating factor [GM-CSF]) are allowed only in cases of neutropenic fever or as clinically indicated per product label. - Prophylactic antithrombotic therapy is permitted. - Thrombopoietin and platelet transfusions are permitted. - Treatment with systemic corticosteroids is permitted for nonhematological conditions providing the subject is receiving a constant dose equivalent to ≤ 10 mg prednisone during the study. - Administration of attenuated vaccines (eg, influenza vaccine) is allowed if clinically indicated per Investigator discretion. - Iron chelation therapy (ICT) is to be used according to the product label. If the label permits, the ICT dose should be stable during at least the first 24 weeks of IP. Initiation of ICT while within the first 24 weeks of IP should be clinically indicated to treat an AE. Prohibited Concomitant Medications The following concomitant medications are specifically excluded during the course of study treatment: - Cytotoxic, chemotherapeutic, targeted, or investigational agents/therapies (excluding JAK2 inhibitor therapy) - Azacitidine, decitabine, or other hypomethylating agents - Lenalidomide, thalidomide, and pomalidomide - Erythropoietin stimulating agents (ESAs) and other RBC hematopoietic growth factors (eg, IL-3) - Hydroxyurea or other alkylating agents - Androgens (unless given to treat hypogonadism) - Oral retinoids (topical retinoids are permitted) - Arsenic trioxide - Interferon - Anagrelide - Systemic corticosteroids at a dose equivalent to > 10 mg prednisone - Investigational products for the treatment of MPN-associated MF

Females of childbearing potential (FCBP)participating in the study must:. i) Have 2 negative pregnancy tests as verified by the Investigator prior to starting study therapy. She must agree to ongoing pregnancy testing during the study, and after end of IP. This applies even if the subject practices true abstinence* from heterosexual contact. ii) Either commit to true abstinence* from heterosexual contact (which must be reviewed on a monthly basis and source documented) or agree to use, and be able to comply with, effective contraception** without interruption, 28 days prior to starting IP, during the study therapy (including dose interruptions), and for 12 weeks (approximately 5 times the mean terminal half-life of IP based on multiple-dose PK data) after discontinuation of study therapy.

• Male subjects must: Practice true abstinence* (which must be reviewed on a monthly basis) or agree to use a condom during sexual contact with a pregnant female or a female of childbearing potential** while participating in the study, during dose interruptions and for at least 12 weeks (approximately 5 times the mean terminal half-life of IP based on multiple-dose PK data) following IP discontinuation, even if he has undergone a successful vasectomy. i) True abstinence is acceptable when it is in line with the preferred and usual lifestyle of the subject. [Periodic abstinence (eg, calendar, ovulation, symptothermal, postovulation methods) and withdrawal are not acceptable methods of contraception.]. ii) Agreement to use highly effective methods of contraception that alone or in combination result in a failure rate of a Pearl index of less than 1% per year when used consistently and correctly throughout the course of the study.
