A Study to Evaluate Safety, Tolerability, and Pharmacokinetics of Escalating Doses of AGS67E Given as Monotherapy in Subjects With Acute Myeloid Leukemia (AML)
A Phase 1 Study Evaluating Safety, Tolerability, and Pharmacokinetics of Escalating Doses of AGS67E Given as Monotherapy in Subjects With Acute Myeloid Leukemia (AML)
Study Overview
Detailed Description
The study will sequentially evaluate AGS67E given as a 30 minute intravenous (IV) infusion in two different schedules: once every 3 weeks (Q3) and then once weekly for 3 weeks.
The dose escalation follows a 3 + 3 design.
The Data Review Team may expand any dose level or intermediate dose level that has been deemed safe and resulted in at least one subject with a Composite Complete Remission (CRc). An expansion cohort may enroll up to 15 subjects.
