1. RBC-TI rate according to IWG 2018 modified criteria (Time Frame - from Week 1 through Week 24): Evaluation of RBC-TI rate of luspatercept for the treatment of anemia due to IPSS-R very low-, low-, or intermediate-risk MDS in subjects with ring sideroblasts (RS) who require RBC transfusions (according to IWG 2018 criteria).
Secondary outcome:
1. RBC-TI rate according to IWG 2006 criteria (Time Frame - from Week 1 through Week 24 and through Week 52): RBC-TI rates according to IWG 2006 criteria (Weeks 1-24 and Weeks 1-52) will be estimated and 97.5% lower confidence limit will be calculated analogously to the primary endpoint.
2. Median time to RBC-TI (Time Frame - Week 1 through Week 24 and through Week 52): Time to RBC-TI will be summarized only for subjects who achieve RBC TI ≥ 8 weeks on treatment. It is defined as the time between start of IMP and the date onset of TI is first observed (i.e, Day 1 of 56 days without any RBC transfusions).
3. Median Duration of RBC-TI (Time Frame - Week 1 through Week 24 and through Week 52): Duration of RBC-TI will be determined only for subjects who achieve RBC TI ≥ 8 weeks on treatment. Duration of RBC-TI is defined as the longest RBC-TI period during the treatment period. Duration of response starts at the date onset of TI is first observed (i.e, Day 1 of 56 days without any RBC transfusions). Transfusion response ends on the day of the first transfusion given after response is documented. Subjects who maintain RBC-TI through EOT will be censored at the date of treatment discontinuation or death, whichever occurs first.
4. Change in RBC units transfused (Time Frame - Week 9 through Week 24 and Week 37 through Week 52): Total number of RBC units transfused over a fixed 16-weeks period (weeks 9-24; weeks 37-52) will be compared to the total number of RBC units transfused in the 16 weeks immediately prior to first IMP.
5. Proportion of subjects achieving mean Hb increase ≥ 1.0 g/dL (Time Frame - Week 1 through Week 24 and through Week 52): Hemoglobin (Hb) increase ≥ 1.0 g/dL is defined as proportion of subjects with ≥ 1.0 g/dL Hb increase compared to baseline that is sustained over any consecutive 56-day period within a specified timeframe in the absence of RBC transfusions.
6. Proportion of subjects achieving modified hematologic improvement - erythroids (mHI-E) per IWG 2006 criteria (Time Frame - Week 1 through Week 24 and through Week 52)
7. Proportion of subjects achieving hematologic improvement - neutrophils (HI-N) per IWG 2006 criteria (Time Frame - Week 1 through Week 24 and through Week 52)
8. Proportion of subjects achieving hematologic improvement - platelets (HI-P) per IWG 2006 criteria (Time Frame - Week 1 through Week 24 and through Week 52)
9. Mean change in serum ferritin (Time Frame - Week 9 through Week 24 and Week 37 through Week 52): Mean change in serum ferritin (Week 9-24; Weeks 37-52) is calculated as the difference of post-baseline mean serum ferritin and baseline mean serum ferritin.
10. Mean Change in Mean Daily Dose of Iron Chelation Therapy (ICT) (Time Frame - Week 9 through Week 24 and Week 37 through Week 52): The change in daily dose for each subject is calculated as the difference of post-baseline mean daily dose and baseline mean daily dose.
11. Proportion of subjects with progression to AML (acute myeloid leukemia) (Time Frame - Week 1 to Week 52): Time to progression to AML is defined as the time between baseline (day1 of IMP administration) and first diagnosis of AML as per WHO classification of ≥ 20% blasts in peripheral blood or bone marrow.
12. Overall survival (Time Frame - Week 1 to Week 52): Overall survival (OS) is defined as the time between start of IMP and death.
13. Change in PRO (Time Frame - Week 1 to Week 52 and to EOT): In order to evaluate the Change in PRO questionnaires (from Week 1 to Week 52 and to EOT) utilizing EORTC QLQ-C30, changes from baseline in overall score and sub-scores will be calculated.
14. Change in PerfO (Time Frame - Week 1 to Week 52 and to EOT): In order to evaluate the Change in PerfO questionnaires (from Week 1 to Week 52 and to EOT) utilizing "Timed Up and Gotest" (TUG), changes from baseline in overall score and sub-scores will be calculated.
