Phase I/II Study of Mitoxantrone, Etoposide and Gemtuzumab Ozogamicin for Acute Myeloid Leukemia

Phase 1

Terminated

• Conditions: Acute Myeloid Leukemia
• Interventions: Drug: Gemtuzumab ozogamicin; Drug: Mitoxantrone; Drug: Etoposide

• Registration Number: NCT00660036
• Lead Sponsor: University of Pittsburgh

Brief Summary

The purpose of this study is to investigate the combination of gemtuzumab ozogamicin, mitoxantrone and etoposide as second line therapy in patients with acute myeloid leukemia.

Detailed Description

The combination of mitoxantrone and etoposide is an active regimen in refractory/relapsed AML patients. In order to improve the efficacy of mitoxantrone and etoposide as second line therapy in patients with AML we proposed to conduct a phase I/II clinical trial combining gemtuzumab ozogamicin with mitoxantrone and etoposide. The phase I portion of the trial will determine the maximum tolerated dose of gemtuzumab ozogamicin combined with mitoxantrone and etoposide and the phase II portion of the trial will determine the efficacy and safety of the combined regimen in patients with AML.
