Eligibility
Key inclusion criteria
Subjects must satisfy the following criteria to be enrolled in the study:

1. Male or female, =18 years of age at the time of signing the informed consent document (ICF).
2. Subject must understand and voluntarily sign an Inform Consent Form prior to any study-related assessments/procedures being conducted.
3. Subject is willing and able to adhere to the study visit schedule and other protocol requirements.
4. Documented diagnosis of ß-thalassemia or Hemoglobin E/ß-thalassemia. (ß-thalassemia with mutation and/or multiplication of alpha globin is allowed).
5. Regularly transfused, defined as: 6-20 Red Blood Cell (RBC) units* in the 24 weeks prior to randomization and no transfusion-free period for = 35 days during that period.

* Sites who prescribe transfusions and have the transfusion records only in volumes should use for conversion of volume to units the below criteria, in order to obtain number of units within the last 24 weeks to assess the eligibility: 1 unit in this protocol refers to a quantity of packed RBCs approximately 200-350 mL. (i) sites who use transfusion bags within this range, or = 350 mL, the conversion in units should be done by dividing the volume transfused to the patient by 350 mL, (ii) sites who use transfusion bags < 200 mL, the conversion in units should be done by dividing the volume transfused to the patient by 200 mL.
6. Performance status: Eastern Cooperative Oncology Group (ECOG) score of 0 or 1.
7. 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). FCBP participating in the study must:

1. Have two 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.
2. 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 with, effective*** contraception without interruption, 28 days prior to starting investigational product, during the study therapy (including dose interruptions), and for 12 weeks (approximately five times the mean terminal half-life of luspatercept based on multiple-dose Pharmacokinetic PK) data) after discontinuation of study therapy.

* True abstinence is acceptable when this is in line with the preferred and usual lifestyle of the subject. [Periodic abstinence (eg, calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception.] *** 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.

Such methods include: Combined (estrogen and progesterone/progestin containing) hormonal contraception: Oral; Intravaginal; Transdermal; Progestogen/progestin only hormonal contraception associated with inhibition of ovulation: Oral; Injectable hormonal contraception; Implantable hormonal contraception; Placement of an intrauterine device (IUD); Placement of an intrauterine hormone-releasing system (IUS); Bilateral tubal occlusion; Vasectomized partner; Sexual Abstinence.
8. Male subjects must:

* Practice true abstinence 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 five times the mean terminal half-life of luspatercept based on multiple-dose PK data) following investigational product discontinuation, even if he has undergone a successful vasectomy.

Key exclusion criteria
The presence of any of the following will exclude a subject from enrollment:

3. Any condition that confounds the ability to interpret data from the study.
4. A diagnosis of Hemoglobin S/ß-thalassemia or alpha (a)-thalassemia (eg, Hemoglobin H);

8. Platelet count > 1000 x 109/L
9. Poorly controlled diabetes mellitus within 24 weeks prior to randomization as defined by short term (eg, hyperosmolar or ketoacidotic crisis) and/or history of diabetic cardiovascular complications (eg, stroke or myocardial infarction).
10. Treatment with another investigational drug or device = 28 days prior to randomization.
11. Prior exposure to sotatercept (ACE-011) or luspatercept (ACE-536).

14. Hydroxyurea treatment = 24 weeks prior to randomization.
15. Pregnant or lactating females.
16. Uncontrolled hypertension. Controlled hypertension for this protocol is considered = Grade 1 according to NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 (current active minor version).

2. Heart disease, heart failure as classified by the New York Heart Association (NYHA) classification 3 or higher, or significant arrhythmia requiring treatment, or recent myocardial infarction within 6 months of randomization.
3. Lung disease, including pulmonary fibrosis or pulmonary hypertension which are clinically significant ie, = Grade 3 NCI CTCAE version 4.0 (current active minor version).
4. Creatinine clearance < 60 mL/min (per Cockroft-Gault formula).
18. Proteinuria = Grade 3 according to NCI CTCAE version 4.0 (current active minor version).
19. Chronic systemic glucocorticoids = 12 weeks prior to randomization (physiologic replacement therapy for adrenal insufficiency is allowed). Single day glucocorticoid treatment (eg, for prevention or treatment of transfusion reactions, is allowed).
20. Major surgery = 12 weeks prior to randomization (subjects must have completely recovered from any previous surgery prior to randomization).
21. History of severe allergic or anaphylactic reactions or hypersensitivity to recombinant proteins or excipients in the investigational product (see Investigator Brochure).
