About this trial
This is a single arm open-label Phase II trial of luspatercept and darbepoetin alfa in non-mutated SF3B1 , lower-risk, RBC transfusion dependent MDS participants with an endogenous erythropoietin (EPO) level \< 500 IU/L.
Eligibility criteria
Qualifiers
Ability to understand and the willingness to sign a written informed consent document.
Participant is 18 years or older at the time of signing informed consent.
Participant has lower-risk myelodysplastic syndrome (MDS) defined as very low, low and intermediate risk by International Prognostic Scoring System-Revised (IPSS-R) criteria (3).
Bone marrow biopsy within 90 days of screening demonstrated less than 5% blasts in the aspirate and/or core biopsy. If no bone marrow biopsy was done within 90 days of screening it is mandatory to repeat it at screening. Otherwise, bone marrow biopsy is optional at screening to obtain correlative study samples.
Disqualifiers
Prior treatment with ESA, luspatercept, hypomethylating agents or lenalidomide/thalidomide/other immunomodulating drug (IMiDs).
Exception 1: Participants can have received ≤ 2 doses of prior epoetin alfa or ≤ 1 dose darbepoetin alfa if ≥ 8 weeks from date of consent.
Exception 2: Participants can have received ≤ 1 week of treatment with lenalidomide ≥ 8 weeks from the date of consent, at the sponsor-investigator's discretion.
After signing consent, the participants are not allowed to receive any of these drugs: other RBC hematopoietic growth factors (e.g., Interleukin-3), granulocyte colony stimulating factors (i.e., G-CSF, GM-CSF), except in cases of neutropenic fever, cytotoxic, chemotherapeutic, targeted or investigational agents/therapies, azacitidine, decitabine or other hypomethylating agents, lenalidomide, thalidomide and other immunomodulating drugs (IMiDs), hydroxyurea, androgens, unless to treat hypogonadism, oral retinoids (topical retinoids are permitted), arsenic trioxide, interferon and interleukins.
