Trial Information

A Phase II Study Of Troxatyl In Patients With CML Blastic Phase Disease

OBJECTIVES: I. Determine the response rate, in terms of achieving complete hematologic
remission, partial hematologic remission, hematologic improvement, partial response, or back
to chronic phase status, in patients with blastic phase chronic myelogenous leukemia treated
with troxacitabine. II. Determine the proportion of patients whose disease returns to
chronic phase and remains at that level for at least 3 months when treated with this drug.
III. Determine the toxicity profile of this drug in these patients. IV. Determine the
duration of survival of patients treated with this drug.

OUTLINE: This is a multicenter study. Patients receive troxacitabine IV over 30 minutes on
days 1-5. Treatment repeats every 4 weeks in the absence of disease progression or
unacceptable toxicity. Patients are followed every 4 weeks until relapse.

PROJECTED ACCRUAL: A maximum of 50 patients will be accrued for this study within 14 months.

Inclusion Criteria

prior investigational agents and recovered No other concurrent investigational agents
