A Study of CG-806 in Patients With Relapsed or Refractory AML or Higher-Risk MDS

A Phase 1a/b Trial of CG-806 in Patients With Relapsed/Refractory Acute Myeloid Leukemia or Higher-Risk Myelodysplastic Syndromes

This study is being done to evaluate the safety, tolerability and antitumor activity of oral CG-806 (luxeptinib) for the treatment of patients with Acute Myeloid Leukemia (except APML), secondary AML, therapy-related AML, or higher-risk MDS, whose disease has relapsed, is refractory or who are ineligible for or intolerant of intensive chemotherapy or transplantation.

This is a multicenter, open-label, Phase 1 a/b dose escalation study of safety, pharmacodynamics, and pharmacokinetics of CG-806 in ascending cohorts (3+3 design) to determine the MTD or recommended dose in patients with relapsed or refractory Acute Myeloid Leukemia (except APML), secondary AML, therapy-related AML, or higher-risk MDS whose disease has relapsed, is refractory or who are ineligible for or intolerant of intensive chemotherapy or transplantation. This is to be followed by a cohort expansion phase.
