Outcome Measures

Primary Outcomes (2)

  • Part A : Dose-finding study

    To determine the optimal dose level in terms of both toxicity and efficacy for luspatercept + EPO

    Evaluation of Dose-limiting toxicity (DLT) at Day 21 of cycle 1 for non-hematological toxicity , up to day 42 for hematological toxicity

  • Part B : Benefit of the association over the monotherapy

    To determine, at Week 25, the superiority and efficacy of luspatercept + ESA over luspatecept alone

    At week 25

Secondary Outcomes (3)

  • Response rate

    3 months

  • Response duration

    24 months

  • Overall survival

    30 months

Study Arms (2)

Arm A (Luspatercept alone)

EXPERIMENTAL

Patients will receive Luspatercept 1mg/kg (every 3 weeks) with titration up to max of 1.75mg/kg, subcutaneously on day 1 of each 21 day cycle (every three weeks).

Drug: Luspatercept Injection [Reblozyl]

Arm B (Luspatercept + EPREX)

EXPERIMENTAL

Patients will receive Luspatercept (at the selected dose according to part A) subcutaneously on day 1 of each 21 day cycle (every three weeks) AND Epoetin alfa: At the selected dose (in part A) per week, subcutaneously, every week Doses schedules Part A : * Level 1 : Luspatercept 0.8 mg/kg + EPREX 30000 UI * Level 2 : Luspatercept 1.33 mg/kg + EPREX 30000 UI * Level 3 : Luspatercept 1.75mg/kg + EPREX 30000 UI * Level 4 : Luspatercept 1.75mg/kg + EPREX 60000 UI

Drug: Luspatercept Injection [Reblozyl]Drug: Eprex

Interventions

All patients will receive Luspatercept subcutaneously on day 1 of each 21 day cycle (every 3 weeks) at the selected dose according to part A : 1.75mg/kg or 1.33 mg/kg or 0.8 mg/kg

Also known as: ACE-536
Arm A (Luspatercept alone)Arm B (Luspatercept + EPREX)
EprexDRUG

Epoietin alfa will be adminstered as a subcutaneous injection at the selected dose according to part A : 30 000 UI/week or 60 000 UI/week, every week

Also known as: Epoietin alfa
Arm B (Luspatercept + EPREX)

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients must meet all of the following criteria to participate in the study:
  • Myelodysplastic syndrome according to current WHO classification
  • Age ≥ 18 years
  • Patients with lower risk MDS according to IPSS classification (LOW, INT-1) without RS who failed to achieved a response or who subsequently relapse after ESA (at least 60000 U EPO-a over at least 12weeks or equivalent), without disease progression (or ineligible to ESA defined by EPO \> 500 UI/l)
  • Hemoglobin \< 9 gr/dl or Transfusion dependant (at least 3 RBCs in 16 wk in at least 2 transfusion episodes)
  • Non del(5q) syndrome
  • Adequat renal function, defined by creatinine less than 1.5 times the upper limit of normal, creatinine clearance ≥ 40 mL/min (MDRD formula).
  • Adequat liver function, defined by total bilirubin and transaminases less than 1.5 times the upper limit of normal.
  • Patient is not known to be refractory to platelet transfusions.
  • Written informed consent.
  • Patient must understand and voluntarily sign consent form.
  • Patient must be able to adhere to the visit schedule as outlined in the study and follow protocol requirements.
  • ECOG performance status 0-2 at the time of screening.
  • A FCBP (female of childbearing potential) for this study was defined as a sexually mature woman who: (1) had not undergone a hysterectomy or bilateral oophorectomy; or (2) had not been naturally postmenopausal (amenorrhea following cancer therapy did 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 had 2 negative pregnancy tests as verified by the investigator prior to starting IP (unless the screening pregnancy test was done within 72 hours of Cycle 1 Day 1). She must have had agreed to ongoing a monthly pregnancy testing during the course of the study and after EOT
  • +3 more criteria

You may not qualify if:

  • A patient meeting any of the following criteria is not eligible to participate in the study:
  • Severe infection or any other uncontrolled severe condition.
  • Uncontrolled hypertension
  • Significant cardiac disease - NYHA Class III or IV or having suffered a myocardial infarction in the last 6 months.
  • del(5q) syndrome
  • Use of investigational agents within 30 days or any anticancer therapy (including IMiD) within 2 weeks before the study entry with the exception of hydroxyurea. The patient must have recovered at least a grade 1 from all acute toxicity from any previous therapy.
  • Use of EPO within 4 weeks before the study entry
  • Active cancer, or cancer during the year prior to trial entry other than basal cell carcinoma, or carcinoma in situ of the cervix or breast.
  • Patient already enrolled in another therapeutic trial of an investigational drug.
  • Known HIV infection or active hepatitis B or C.
  • Women who are or could become pregnant or who are currently breastfeeding.
  • Any medical or psychiatric contraindication that would prevent the patient from understanding and signing the informed consent form.
  • Patient eligible for allogeneic stem cell transplantation.
  • Known allergies to luspatercept or EPO or any of its excipients.
  • No affiliation to a health insurance system.
