Trial of Sirolimus and Methotrexate in Relapsed/Refractory Lymphoblastic Leukemia and Lymphoma

Summary

This is a phase 2 study looking at efficacy and toxicity of oral sirolimus in combination with oral methotrexate in children with refractory/relapsed ALL or NHL. Secondary objectives include characterizing the trough levels produced by administration of oral sirolimus in children with refractory/relapsed ALL/NHL and to evaluate the effect of sirolimus on intracellular targets related to mTOR inhibition.
