What was measured

Cytogenic partial response was evaluated by detection of chromosomal abnormalities by cytogenic techniques and assessed according to the International Working Group (IWG) response criteria in myelodysplasia per Cheson et al. 2006. Cytogenic partial response was defined as ≥50% reduction of the chromosomal abnormality detected pre-treatment. The percentage of participants with cytogenic partial response as assessed by the investigator is presented.

Analysis population: All participants in Cohort 1 with a baseline efficacy evaluation and at least 1 post-baseline efficacy evaluation.
