Trial Information

A Phase I Trial Of Sirolimus In Relapsed/Refractory Leukemia And Non-Hodgkin's Lymphoma


OBJECTIVES:

- Determine the maximum tolerated dose of sirolimus in pediatric patients with refractory
or relapsed acute leukemia or non-Hodgkin's lymphoma.

- Determine the dose-limiting toxic effects of this drug in these patients.

- Determine the trough levels produced by this drug in these patients.

- Determine the anti-leukemia/lymphoma activity of this drug in these patients.

OUTLINE: This is an open-label, dose-escalation study.

Patients receive oral sirolimus once daily on days 1-21. Courses repeat every 21 days in the
absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of sirolimus 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.

Patients are followed for survival.

PROJECTED ACCRUAL: A total of 3-30 patients will be accrued for this study within 2 years.
