Primary Outcome Measures:
  • CR [ Time Frame: After induction therapy is completed ] [ Designated as safety issue: No ]

Estimated Enrollment: 35
Study Start Date: July 2000
Study Completion Date: July 2004
Primary Completion Date: June 2004 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: nelarabine
    1.5 gm/m2 IV over 2 hours days 1, 3, 5 q21 days
Detailed Description:


  • Assess the complete remission rate in patients with recurrent or refractory non-T-cell acute lymphocytic leukemia when treated with 506U78.
  • Determine the frequency and severity of toxic effects of this drug in these patients.

OUTLINE: This is a multicenter study.

Patients receive 506U78 IV over 2 hours on days 1, 3, and 5. Treatment continues every 21 days for up to 4 courses in the absence of disease progression or unacceptable toxicity.

Patients are followed every month for 6 months, every 3 months for 1 year, and then every 6 months for 3.5 years.

PROJECTED ACCRUAL: A total of 20-35 patients will be accrued for this study within 18 months.
