A Safety Study of SGN-CD33A in AML Patients
A Phase 1 Trial of SGN-CD33A in Patients With CD33-positive Acute Myeloid Leukemia

This study will examine the safety profile of SGN-CD33A administered as a single agent and in combination with a hypomethylating agent (HMA). The main purpose of the study is to find the maximum tolerated dose (MTD, which is the highest dose that does not cause unacceptable side effects) of SGN-CD33A in patients with acute myeloid leukemia (AML). The MTD 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-leukemia activity of SGN-CD33A will be assessed.
