GTI-2040 and High-Dose Cytarabine in Treating Patients With Refractory or Relapsed Acute Myeloid Leukemia

June 3, 2013 updated by: National Cancer Institute (NCI)

A Phase I Study of GTI2040 (NSC 722929; IND 67368) in Combination With High-dose Cytarabine in Refractory or Relapsed Acute Myeloid Leukemia (AML)

This phase I trial is studying the side effects and best dose of GTI-2040 and high-dose cytarabine in treating patients with refractory or relapsed acute myeloid leukemia. GTI-2040 may stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth. Drugs used in chemotherapy, such as cytarabine, use different ways to stop cancer cells from dividing so they stop growing or die. Giving GTI-2040 together with cytarabine may kill more cancer cells.

Study Overview

Detailed Description

PRIMARY OBJECTIVES:

I. Determine the maximum tolerated dose and recommended phase II dose of GTI-2040 and high-dose cytarabine in patients with relapsed or refractory acute myeloid leukemia.

SECONDARY OBJECTIVES:

I. Determine the therapeutic response in patients treated with this regimen. II. Determine the pharmacokinetics of this regimen in these patients.

OUTLINE: This is a dose-escalation study. Patients are stratified according to age (under age 60 vs age 60 and over). Patients are assigned to 1 of 2 strata.

Stratum I (under age 60): Patients receive GTI-2040 IV continuously on days 1-6 and high-dose cytarabine IV over 2 hours twice daily on days 2, 4, and 6.

Stratum II (age 60 and over): Patients receive GTI-2040 IV continuously on days 1-6 and high-dose cytarabine IV over 4 hours once daily on days 2-6.

In both strata, treatment continues in the absence of unacceptable toxicity.

Cohorts of 3-6 patients per stratum receive escalating doses of GTI-2040 and high-dose cytarabine until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.

PROJECTED ACCRUAL: A total of 6-51patients will be accrued for this study within 2-16 months.
