A Study of Evorpacept (ALX148) With Venetoclax and Azacitidine for Acute Myeloid Leukemia (ASPEN-05)
- Conditions
- Acute Myeloid LeukemiaAML, Adult
- Interventions
- Registration Number
- NCT04755244
- Lead Sponsor
- ALX Oncology Inc.
- Brief Summary
This Phase 1/2 clinical study will evaluate evorpacept (ALX148) in combination with venetoclax and azacitidine for the treatment of patients with acute myeloid leukemia (AML).
- Detailed Description
The Phase 1 will consist of a dose escalation of evorpacept (ALX148) in combination with venetoclax and azacitidine to evaluate safety and tolerability, and to identify the recommended Phase 2 dose of evorpacept (ALX148) in combination with venetoclax and azacitidine. The Phase 2 will evaluate the efficacy of evorpacept (ALX148) in combination with venetoclax and azacitidine for patients with AML. While intended to be a Phase 1/2 clinical study, the study never moved forward to Phase 2.
