Estimated Enrollment: 124
Study Start Date: March 2016
Estimated Study Completion Date: March 2019
Estimated Primary Completion Date: December 2018 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Dose Escalation Schedule A
IMGN779 administered on days 1 and 15 of a 28-day cycle
Drug: IMGN779
Experimental: Dose Escalation Schedule B
IMGN779 administered on days 1, 8, 15 and 22 of a 28-day cycle
Drug: IMGN779
Experimental: Dose Expansion Cohort 1
Patients with AML at first relapse occurring within12 months; IMGN779 administered at dose and schedule selected.
Drug: IMGN779
Experimental: Dose Expansion Cohort 2
Patients with Relapse Refractory AML; IMGN779 administered at dose and schedule selected.
Drug: IMGN779

Detailed Description:
In the Dose Escalation Phase, patients will be assigned to one of two schedules. The MTD for both schedules will be determined from the assessment of Dose Limiting Toxicities (DLTs). The Dose Expansion Phase will consist of two cohorts based on patients response to prior therapy according to the MTD selected.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Dose Escalation: Patients with relapsed or refractory AML
  • Dose Expansion Cohort 1: Patients with relapsed AML or patients who refuse, or ar not suitable candidates for induction therapy
  • Dose Expansion Cohort 2: Patients with refractory AML

Exclusion Criteria:

  • Dose Escalation: Acute Promyelocytic Leukemia
  • Any concurrent anti-cancer therapy including chemotherapy, immunotherapy, radiotherapy, biologic or any investigational agents (with the exception of hydroxyurea or leukapheresis for control of hyperleukocytosis) within 14 days or five half-lives of drugs, whichever is shorter, prior to Cycle 1 Day 1
  • AML patients with known, active leptomeningeal/central nervous system (CNS) involvement
  • Prior treatment with IMGN779
  • Women who are pregnant or breast feeding
