Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will examine the safety profile of vadastuximab talirine (SGN-CD33A) by itself (monotherapy) or in combination with other standard treatments. The main purpose of this study is to find the best dose and schedule for SGN-CD33A when given in combination with standard induction treatment, in combination with standard consolidation treatment, or by itself for maintenance treatment. This will be determined by observing the dose-limiting toxicities (the side effects that prevent further increases in dose) of SGN-CD33A. In addition, the pharmacokinetic profile and anti-leukemic activity of the study treatment will be assessed.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study will be conducted in the following distinct parts:

Part A: Induction dose escalation - 7+3 combined with SGN-CD33A (Day 1 and Day 4 dosing)

Part B: Consolidation dose escalation - consolidation combined with SGN-CD33A; up to 4 cycles of consolidation therapy will be administered after SGN-CD33A (Day 1 of each cycle).

Part C: Maintenance - SGN-CD33A Monotherapy; Up to 24 patients with and up to 24 patient without prior allogeneic stem cell transplant will be treated with SGN-CD33A. Both arms will enroll simultaneously. SGN-CD33A will be administered on Day 1 of each 6-week cycle for up to 8 cycles.

Part D: Induction plus consolidation - induction/consolidation combined with SGN-CD33A; patients who achieve a CR/CRi (with or without a second induction) will receive up to 4 cycles of consolidation therapy administered after SGN-CD33A (Day 1 of each cycle).

Part E: Induction dose escalation - 7+3 combined with SGN-CD33A (Day 1 dosing)
