Medical Use

Reblozyl is an erythroid maturation agent used to treat:

  • Anemia in adults with beta (β) thalassemia who require regular red blood cell (RBC) transfusions.
  • Anemia in adults with very low- to intermediate-risk myelodysplastic syndromes with ring sideroblasts (MDS-RS) or myelodysplastic/myeloproliferative neoplasm with ring sideroblasts and thrombocytosis (MDS/MPN-RS-T), who have failed an erythropoiesis-stimulating agent and need two or more RBC units over 8 weeks.

Limitations of Use: Reblozyl is not intended as a substitute for RBC transfusions in patients needing immediate anemia correction.

Recommended Dosage: The starting dose is 1 mg/kg administered subcutaneously every 3 weeks for patients with beta thalassemia. Before each dose, review the patient’s hemoglobin levels and transfusion history, and adjust the dose based on response.

Discontinue treatment if there is no reduction in transfusion burden after 9 weeks (3 doses) at the maximum dose or if unacceptable toxicity occurs. If a dose is missed or delayed, administer it as soon as possible and continue with the regular schedule, ensuring at least three weeks between doses.
