Official Title

(COMMANDS) - A Phase 3, Open-label, Randomized Study to Compare the Efficacy and Safety of Luspatercept (ACE-536) Versus Epoetin Alpha for the Treatment of Anemia Due to IPSS-R Very Low, Low or Intermediate Risk Due to Myelodysplastic Syndrome (MDS)


This is an interventional active-controlled, open-label, randomized Phase 3 study to compare the efficacy and safety of luspatercept (ACE-536) versus epoetin alfa for the treatment of anemia due to IPSS-R very low, low or intermediate risk MDS in ESA naïve subjects who require RBC transfusions.

The study is divided into the Screening Period, a Treatment Period and a Post-Treatment Follow-up Period.

Associated Drug(s): 
Phase 3
Age Group: 
18 years and older
Accepts Healthy Volunteers: 
Inclusion Criteria: 

Subjects must satisfy the following criteria to be randomized in the study:

  1. Subject is ≥ 18 years of age the time of signing the informed consent form (ICF).
  2. Subject must understand and voluntarily sign an ICF 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. Subject has a documented diagnosis of MDS according to WHO 2016 classification that meets IPSS-R classification of very low, low, or intermediate risk disease, and:
  5. Subject has an endogenous serum erythropoietin (sEPO) level of < 500 U/L.
  6. Subject requires RBC transfusions, as documented by the following criteria:
    • Average transfusion requirement of 2 - 6 units/8 weeks of pRBCs confirmed for a minimum of 8 weeks immediately preceding randomization.

Red blood cell transfusions administered when Hgb levels were > 9.0 g/dL (or > 7 g/dL in the absence of symptoms) and/or RBC transfusions administered for elective surgery, infections or bleeding events will not qualify as a required transfusion for the purpose of meeting eligibility criteria or stratification.
    • The hemoglobin level after the last RBC transfusion prior to randomization must be < 11.0 g/dL (centrally or locally analyzed).
  7. Subject has Eastern Cooperative Oncology Group (ECOG) score of 0, 1, or 2.
  8. Females of childbearing potential (FCBP), defined as a sexually mature woman who:
    1) has not undergone a hysterectomy or bilateral oophorectomy or 2) 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), must:
    • Have two negative pregnancy tests as verified by the investigator prior to starting study therapy (unless the screening pregnancy test was done within 72 hours of W1D1). She must agree to ongoing pregnancy testing during the course of the study, and after end of study treatment.
    • If sexually active, agree to use, and be able to comply with, highly effective contraception without interruption, 5 weeks prior to starting investigational product, during the study therapy (including dose interruptions), and for 12 weeks after discontinuation of study therapy.
  9. Male subjects must:
    • Practice true abstinence (which must be reviewed prior to each IP administration or on a monthly basis [eg, in the event of dose delays]) or agree to use a condom (latex or non-latex, but not made out of natural [animal] membrane) 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 following investigational product discontinuation, even if he has undergone a successful vasectomy.
