- Proportion of patients who have a modified erythroid response (mHI-E). [ Time Frame: Assessed at approximately 28 weeks from patient screening. ]mHI-E defined as a hemoglobin increase of ≥ 1.5 g/dL from baseline for ≥ 14 days (in the absence of red blood cell [RBC] transfusions) in non-transfusion dependent patients, or, a reduction of either ≥ 4 units or ≥ 50% of units of RBCs transfused compared to pre treatment in transfusion dependent patients.
- Number of patients with adverse events. [ Time Frame: From treatment initiation to End-of-Study visit (approximately 28 weeks later). ]
- Rates of erythroid, neutrophil and platelet (HI-E, HI-N and HI-P) responses. [ Time Frame: Measured during any 8 week period on study, up to 28 weeks from patient screening, compared with the 8-week period prior to study day 1. ]
- Time to mHI-E response and HI-E response and duration of mHI-E and HI-E response. [ Time Frame: Measured over the course of study, up to approximately 24 weeks from initiation of dosing on study day 1. ]
- Frequency of RBC transfusions in transfusion-dependent patients. [ Time Frame: Approximately 28 weeks from patient screening. ]
- ACE-536 pharmacokinetics (e.g., serum half-life, peak serum concentration, time to peak concentration, etc.). [ Time Frame: Measured at multiple time points over the course of treatment, from study day 1 to approximately 24 weeks. ]
