Brief Summary:
The study design includes a 3-dose randomization phase to determine effective doses of INCB047986 in patients with myelodysplastic syndrome (MDS) who are refractory or unlikely to respond to erythropoiesis-stimulating agents (ESAs) followed by an extension phase.

Condition or disease Intervention/treatment Phase
MDS (Myelodysplastic Syndrome) Drug: INCB047986 Phase 1 Phase 2

Detailed Description:

After 50% of the subjects have completed 16 weeks of treatment (10 subjects in each dose group), a planned interim analysis will be conducted to determine which, if any, dose levels warrant further investigation based on observing at least 3 responses for hematologic improvement in erythrocytes (HI-E) and adequate safety and tolerability.

Subjects who do not meet the response criteria for erythroid improvement may be treated with ESA in combination with INCB047986 for an additional 16 weeks.

The study comprises:

Screening: up to 4 weeks. Treatment Phase 1: at least 16 weeks of INCB047986. Treatment Phase 2: at least 8 and up to 16 weeks of INCB047986 in combination with ESA if failed treatment in Phase 1.

Extension Phase: Subjects receiving benefit from either therapy may continue indefinitely or until the study is terminated.

Follow-Up: 30 (± 7) days after the last dose of INCB047986 is taken.
