Design outcomes

Primary

MeasureTime frame
Main Objective: Part 1: Dose Escalation • To evaluate the safety and tolerability of ascending doses of KER-050 in participants with very low, low, or intermediate risk MDS in order to determine the dose(s) that will be evaluated in Part 2 of the study. Part 2: Dose Confirmation • To confirm the safety and tolerability of the dose(s) selected in Part 1. Long-Term Extension •To evaluate the long-term safety and tolerability of KER-050 in participants with very low, low, or intermediate risk MDS in the Long Term Extension (LTE).;Secondary Objective: Secondary objectives (all parts) Safety Objective: •To evaluate the progression to higher risk MDS or acute myeloid leukemia (AML) Efficacy Objective: •To evaluate the efficacy of KER-050 on anemia in participants with very low, low, orintermediate risk MDS, separately for ring sideroblast (RS)-positive and non-RS populations Pharmacodynamic Objective: •To evaluate the pharmacodynamic (PD) effects of KER-050 on erythropoiesis in participants with very low, low, or intermediate risk MDS, separately for RS-positive and non-RS populations;Primary end point(s): Part 1 and Part 2: •Safety and tolerability as determined by the incidence of treatment emergent adverse events(TEAEs) and serious adverse events (SAEs). Long-term Extension: •Safety and tolerability as determined by the incidence of TEAEs and SAEs over time;Timepoint(s) of evaluation of this end point: 105 Weeks unless participants elect to continue in the Long-term Extension (LTE)

Secondary

MeasureTime frame
Secondary end point(s): 1. Incidence of progression to higher risk MDS or AML per World Health Organization (WHO) 2016 criteria. 2. Proportion of low transfusion burden (LTB) and high transfusion burden (HTB) participants who achieve red blood cell (RBC) transfusion independence (TI) = 8 weeks, overall and by RS status. 3. Proportion of participants who achieve modified 2006 International Working Group (IWG) Hematologic Improvement-Erythroid (HI E) response overall and by RS status, where: - In LTB participants and participants with non-transfused anemia, response is defined as a mean hemoglobin (Hgb) increase of = 1.5 g/dL from Baseline during any 8 week period during the treatment period. - In HTB participants, response is defined as a reduction by = 4 units of RBCs transfused during any 8-week period on study compared with the 8-week period prior to study Cycle 1 Day 1 (C1D1). 4. Proportion of participants who achieve overall erythroid response, defined as either HI-E or TI over any 8-week period, overall and by RS status. 5. Proportion of participants who achieve erythropoietic improvement overall and by RS status, where: - In low-transfusion burden (LTB) participants and participants with non-transfused anemia, improvement is defined as a mean hemoglobin (Hgb) increase of = 1.5 g/dL from Baseline for = 14 days (in the absence of red blood cell [RBC] transfusions). - In high transfusion burden (HTB) participants, improvement is defined as a reduction of = 50% or = 4 RBC units transfused compared to pretreatment over an 8-week period. 6. Mean change from baseline in hemoglobin [Time Frame: Measured over the course of study, up to approximately 25 weeks from study day 1 unless participants elect to continue on in the LTE]. 7. Time to HI-E response [Time Frame: From treatment initiation to End of Study visit (approximately 25 weeks unless participants elect to continue on in the LTE)]. 8. Duration of HI-E response [Time Frame: From treatment initiation to End of St
