Summary

This trial tests a new drug, IMGN632, combined with other drugs to treat patients with a specific type of leukemia. It aims to see if this combination can effectively target and kill cancer cells while stopping them from growing.

Who is the study for?
Adults with CD123-positive Acute Myeloid Leukemia (AML) who have either relapsed or are treatment-naive can join this trial. They must be fit for experimental therapy, not have acute promyelocytic leukemia, and should not have had certain prior treatments. Participants need normal organ function and controlled previous cancers if any.
What is being tested?
The safety and effectiveness of IMGN632 alone or combined with azacitidine and/or venetoclax in treating AML are being tested. This study is open-label, meaning everyone knows which treatment they're getting, and it's happening at multiple centers.
What are the potential side effects?
Possible side effects include reactions related to the immune system due to monoclonal antibodies like IMGN632, liver issues from azacitidine or venetoclax, blood count changes, fatigue, digestive problems, and potential increased risk of infections.

Trial Design

4Treatment groups
Experimental Treatment
Group I: Regimen D (Closed to Enrollment)Experimental Treatment1 Intervention
IMGN632, administered intravenously on Day 1 of a 21 day cycle at 0.045 mg/kg, as a monotherapy for Fit and Unfit MRD+ patients.
Group II: Regimen C - Frontline & Relapsed / Refractory (Closed to Enrollment)Experimental Treatment3 Interventions
IMGN632, administered intravenously on Day 7 of a 28 day cycle at 0.015 mg/kg or 0.045 mg/kg, in combination with azacitidine, administered subcutaneously or intravenously daily at 35-75 mg/m2 given for Days 1 to 7 of a 28 day cycle and venetoclax, administered orally daily at 100 mg on Day 1, 200mg on Day 2, and 400 mg on Day 3 up to Day 28 of a 28 day cycle. Alternate schedules with reduced venetoclax administration or reduced azacitidine dose or administration may be explored.
Group III: Regimen B (Closed to Enrollment)Experimental Treatment2 Interventions
IMGN632, administered intravenously on Day 7 of a 21 day cycle at 0.015 mg/kg, 0.045 mg/kg, or 0.09 mg/kg, in combination with venetoclax, administered orally daily at 100 mg on Day 1, 200mg on Day 2, and 400 mg on the day 3 up to Day 21 of a 21 day cycle. Alternate schedules with reduced venetoclax administration may be explored.
Group IV: Regimen A (Closed to Enrollment)Experimental Treatment2 Interventions
IMGN632, administered intravenously on Day 7 of a 28 day cycle at 0.015 mg/kg, 0.045 mg/kg, or 0.09 mg/kg, in combination with azacitidine, administered subcutaneously or intravenously daily at 75 mg/m2 on Days 1 to 7 of a 28 day cycle. Cycle 1 azacitidine dose in subsequent cohorts may be reduced.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Common treatments for Acute Myeloid Leukemia (AML) include chemotherapy, targeted therapies, and immunotherapies. Chemotherapy agents like cytarabine and daunorubicin work by interfering with DNA replication, leading to cell death. Targeted therapies, such as FLT3 inhibitors, specifically inhibit mutant proteins that drive leukemia cell proliferation. Immunotherapies, including monoclonal antibodies like IMGN632, target specific antigens such as CD123 on leukemia cells, delivering cytotoxic agents directly to the cancer cells. These mechanisms are crucial for AML patients as they offer more precise and effective treatment options, potentially reducing side effects and improving outcomes by directly targeting the malignant cells.
