A Study to Determine the Efficacy and Safety of Luspatercept in Adults With Non Transfusion Dependent Beta (β)-Thalassemia
a study on Thalassemia
This is a Phase 2, double-blind, randomized, placebo-controlled, multicenter study to determine the efficacy and safety of luspatercept (ACE-536) versus placebo in adults with non-transfusion dependent beta (β)-thalassemia. The study is divided into the Screening Period, Double-blind Treatment Period (DBTP), Open-label Phase (OLP), and Post-Treatment Follow-up Period (PTFP). It is planned to randomize approximately 150 subjects at a 2:1 ratio of luspatercept versus placebo.
A Phase 2, Double-Blind, Randomized, Placebo-Controlled Multicenter Study to Determine the Efficacy and Safety of Luspatercept (ACE-536) Versus Placebo in Adults With Non-Transfusion Dependent Beta (β)-Thalassemia (The BEYOND™ Study)
The primary objective is: - To evaluate the effect of luspatercept (BMS-986346) versus placebo on anemia, as measured by mean hemoglobin concentration in the absence of transfusions over a continuous 12-week interval, from Week 13 to Week 24, compared to baseline. The secondary objectives are: - To evaluate the effect of luspatercept versus placebo in anemia-related symptoms in participants with β-thalassemia, as measured by non-transfusion dependent β-thalassemia-patient reported outcome (NTDT-PRO) over continuous 12-week intervals (from Weeks 13 to 24 and from Weeks 37 to 48) compared to baseline. - To evaluate the effect of luspatercept versus placebo on functional and health-related quality of life (QoL) as measured by Medical Outcomes Study 36-Item Short Form (SF-36) and Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) questionnaires - To evaluate the long-term effect of luspatercept versus placebo on anemia, as measured by mean hemoglobin concentration in the absence of transfusions over a continuous 12-week interval from Week 37 to Week 48, compared to baseline - To evaluate the effect of luspatercept versus placebo on iron overload, as measured by liver iron concentration (LIC) and iron chelation therapy (ICT) daily dose - To evaluate the effect of luspatercept versus placebo on iron overload, as measured by serum ferritin - To evaluate the duration of erythroid response - To evaluate the effect of luspatercept versus placebo on physical activity measured by 6-minute walk test (6MWT) Safety and Pharmacokinetics (PK) Objectives - To evaluate safety and tolerability of luspatercept, including immunogenicity - To evaluate population pharmacokinetics (PK) of luspatercept in subjects with β-thalassemia The exploratory objectives are: - To evaluate the effect of luspatercept versus placebo on measures of extra-medullary hematopoietic (EMH) masses, bone mineral density, splenomegaly, pulmonary hypertension, and leg ulcers, when present - To evaluate the effect of luspatercept versus placebo on the β-thalassemia severity as measured by the NTDT severity score system - To evaluate the effect of luspatercept versus placebo on the β-thalassemia severity as measured by the Morbidity-free Survival parameters - To examine the relationship of baseline and change in serum Growth Differentiation Factor 11 (GDF11) and other related biomarkers with response to treatment with luspatercept - To examine the effect of luspatercept on fetal hemoglobin (HbF) - To examine the effect of luspatercept on Health Resource Utilization (HRU)

Open to people ages 18 years and up
Subjects must satisfy the following criteria to be enrolled in the study:
- Subjects must be ≥ 18 years of age at the time of signing the informed consent document (ICF).
- Subject must understand and voluntarily sign an ICF prior to any study-related assessments/procedures being conducted.
- Subject is willing and able to adhere to the study visit schedule (eg, not scheduled to receive hematopoietic stem cell transplantation) and other protocol requirements.
- Subject must have documented diagnosis of β-thalassemia or hemoglobin E/ β-thalassemia. Concomitant alpha globin mutation and/or duplication are allowed.
- Subject must be non-transfusion dependent, defined as 0 to 5 units of RBCs received during the 24-week period prior to randomization. Note: 1 unit defined for this entry criterion as approximately 200 to 350 mL of transfused packed RBCs.
- Subject must not be on a regular transfusion program and must be RBC transfusion-free for at least ≥ 8 weeks prior to randomization
- Subject must have mean baseline hemoglobin ≤ 10 g/dL, based on a minimum of 2 measurements ≥ 1 week apart within 4 weeks prior to randomization; hemoglobin values within 21 days post-transfusion will be excluded.
- Subject must have performance status: Eastern Cooperative Oncology Group (ECOG) performance score of 0 to 1.
- A female of childbearing potential (FCBP) for this study is defined as a female who:
1) has achieved menarche at some point, 2) has not undergone a hysterectomy or bilateral oophorectomy or 3) has not been naturally postmenopausal (amenorrhea following cancer therapy does not rule out childbearing potential) for at least 24 consecutive months (ie, has had menses at any time in the preceding 24 consecutive months). A FCBP participating in the study must:
- Have 2 negative pregnancy tests as verified by the Investigator prior to starting study therapy. She must agree to ongoing pregnancy testing during the course of the study, and after end of study treatment. This applies even if the subject practices true abstinence* from heterosexual contact.
- Either commit to true abstinence* from heterosexual contact (which must be reviewed on a monthly basis and source documented). If a FCBP engages in sexual activity that may result in a pregnancy, she must agree to use, and be able to comply during the study therapy (including dose interruptions), and for 12 weeks (approximately 5 times the mean terminal half-life of luspatercept based on multiple dose pharmacokinetics [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 luspatercept based on multiple-dose PK data) following IP discontinuation, even if he has undergone a successful vasectomy
