• | 63% (12 of 19) of HTB and LTB patients with prior ESA treatment achieved an International Working Group (IWG) Hematologic Improvement Erythroid (HI-E) response of a reduction of ≥4 units RBC over 8 weeks or a hemoglobin increase ≥1.5 g/dL for ≥8 weeks during their luspatercept treatment period |
• | 50% (7 of 14) achieved transfusion independence |
• | 71% (5 of 7) achieved an HI-E response and 50% (2 of 4) achieved transfusion independence |
• | 68% (13 of 19) of the HTB patients achieved the IWG HI-E criteria of a reduction of ≥4 units RBC over 8 weeks |
• | 42% (8 of 19) of the HTB patients achieved transfusion independence for ≥8 weeks |
• | 69% (9 of 13) of the LTB patients achieved the IWG HI-E response criteria of a hemoglobin increase ≥1.5 g/dL for ≥8 weeks |
• | The mean increase in hemoglobin reached levels between 2.0 and 2.5 g/dL and was maintained for the 9 months for which data are available |
• | Adverse events at least possibly related to study drug that occurred in patients during the extension study included bone pain, headache, hypotonia, myalgia and nausea. No serious or grade 3 or 4 adverse events related to study drug have been reported during the ongoing extension study. |
