A Study of APTO-253 in Patients With Relapsed or Refractory AML or MDS
Study Details
Study Description
Brief Summary
This study is being done to evaluate the safety and effectiveness of APTO-253 for the treatment of patients with the condition of acute myelogenous leukemia (AML) or myelodysplastic syndrome (MDS) for which either the standard treatment has failed, is no longer effective, or can no longer be administered safely or poses a risk for your general well being.

Phase 1 |
Detailed Description
This is a multicenter, open-label, Phase Ia/b dose escalation study of safety, pharmacodynamics, and pharmacokinetics of APTO-253 in ascending cohorts (3+3 design) to determine the MTD or recommended dose in patients with relapsed or refractory acute myelogenous leukemia (AML) or high-risk MDS patients. This is to be followed by a cohort expansion phase at the MTD or recommended dose.
Study Design
Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Dose Escalation and Expansion APTO-253 will be given in ascending doses in patients with relapsed or refractory AML or high risk MDS (escalation cohort), until the maximum tolerated dose or recommended dose is reached. Followed by up to 30 patients enrolled in the expansion cohort at the recommended dose. |
Drug: APTO-253
APTO-253 will be given in ascending doses starting at 20 mg/m2 until the maximum tolerated dose or recommended dose is reached.
