Further study details as provided by Edward Ball, University of California, San Diego:

Primary Outcome Measures:
  • In Phase I the Maximum Tolerated Dose will be the maximum dose at which fewer than one-third of patients experience Dose Limiting Toxicity [ Time Frame: approximately 4 years ]

Secondary Outcome Measures:
  • In Phase II response to the combination treatment of Mylotarg with 5-azacitidine [ Time Frame: Response will be assessed when evaluated at the time the ANC has reached 1000/mm3 for three consecutive days ]

Enrollment: 50
Study Start Date: July 2005
Estimated Study Completion Date: December 2017
Primary Completion Date: June 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Treatment
5-Azacitidine, Gemtuzumab ozogamicin
Drug: 5-Azacitidine
A = given in cohorts of 3 starting with 2 doses of 5-azacitidine. The doses of 5-azacitidine will be escalated to 4 and then 6 doses if the dose escalation rules permit
Other Name: Vidaz
Drug: Gemtuzumab ozogamicin
M = Mylotarg given 2 times over 2 weeks
Other Name: Mylotarg

Detailed Description:

In the Phase I portion of the study patients with a diagnosis of AML who have relapsed disease will be treated with an assigned number of doses of 5 azacitidine followed by Mylotarg administered two times over two weeks

In the Phase II portion of the study patients will be treated with the dose of 5azacitidine determined to be safe in the Phase I portion of the study followed by Mylotarg.

A sample of blood or bone marrow will be obtained prior to initiation of treatment and another sample obtained after treatment with 5-azacitidine but before Mylotarg and the samples will be tested in the laboratory to determine response to treatment.
