Clinical Trial Summary

The study is a multicenter, open label Phase I/II trial. 1. To determine the maximum tolerated dose (MTD) of lintuzumab-Ac225 when given in combination with venetoclax and azacitidine for patients with CD33 positive AML. (Phase I portion) 2. To assess the percentage of patients with CR, CRh, CRi, MLFS or Overall Response (CR + CRh + CRi + MLFS), up to 6 months after the start of treatment without receiving other AML therapies.. (Phase 2 portion)


Clinical Trial Description

The study is a multicenter, open label Phase I and Phase II trial combining lintuzumab-Ac225 with venetoclax and azacitidine in patients who have relapsed or refractory AML. The Phase I portion is a dose-finding study which will enroll at least three patients at each dose level. Patients in each dose level will be observed for a minimum of 4 weeks before dose escalation occurs. There is no dose escalation for any individual patient. Lintuzumab-Ac225 is administered on Day 8 of the first 4 treatment cycles. The Phase II portion of the study will enroll patients at the MTD dose level of lintuzumab-Ac225 as determined in the Phase I portion of the study. The goal of the Phase II portion will be to further characterize the safety and efficacy of the MTD dose of lintuzumab-Ac225. ;
