Egyéb

• Female patients who are pregnant or lactating.
• Female patients with reproductive potential who do not have a negative urine or blood beta-human chorionic gonadotropin (beta HCG) pregnancy test at screening.

• Age ≥ 18 years; as MDS there is no significant experience with luspatercept in pediatric patients
• Cohorts #1 and #2: Diagnosis of MDS according to WHO 2023 criteria (5) and with low or int-1 risk by IPSS or a score of ≤ 3.5 by IPSS-R.(3, 22)
• Cohort #2: Patient defined as transfusion dependent by documentation of receiving at least 2 units of packed red blood cells (PRBCs) for a hemoglobin of less than 8.0 g/dL during an 8-week period prior to study enrollment.
• Cohort #1: Patients with symptomatic anemia that are transfusion independent defined as not requiring a transfusion for a hemoglobin of less than 8.0 g/dL during an 8-week period prior to study enrollment.
• MDS patients with either a platelet count of ≤100 K/uL and/or ANC of ≤1.8 K/uL
• Patient must have signed an informed consent and is willing to participate in the study.
• Adequate hepatic function with total bilirubin ≤3 x ULN, AST or ALT ≤3xULN.
• Serum creatinine clearance ≥40mL/min and no end/stage renal disease (using Cockcroft-Gault).
