A Study of Efficacy and Safety of AND017 in Patients With Myelodysplastic Syndrome

Diagnosed of primary myelodysplastic syndrome with a PISS-R grading of very low, low or intermediate risk and a bone marrow primitive cell count < 5%, the time frame for this grading assessment should be at least 12 weeks prior to the first dose

Non-5q(del)-associated myelodysplastic syndrome.

Two non-transfused hemoglobin ≥ 6.0 g/dL and < 10.0 g/dL, averaged over the screening period, at least one week and more apart, and with no more than 1.3 g/dL difference between the two Hb.

Non-transfused subjects (NTD cohort) defined as no red blood cell transfusion in the 16 weeks prior to randomization or low transfusion load subjects defined as 3-7 pRBC units transfused in the 16 weeks prior to randomization and at least two different time points (LTB-1 cohort) or 1-2 pRBC units transfused at one time point in the 16 weeks prior to randomization ( LTB-2 cohort) (except in the case of transfusion for treatment of other comorbidities such as blood loss, surgery, etc.);
