Purpose

This Phase 1/2 clinical study will evaluate ALX148 in combination with azacitidine for the treatment of patients with higher risk myelodysplastic syndrome (MDS).

Detailed Description

      The Phase 1 will consist of a dose escalation of ALX148 in combination with azacitidine to
      evaluate safety and tolerability, and to identify the recommended Phase 2 dose of ALX148 in
      combination with azacitidine. The Phase 2 will evaluate the efficacy of ALX148 in combination
      with azacitidine for patients with higher risk MDS.
