Sequential combination of methotrexate and vindesine in previously treated children with acute leukemia. A phase I-II...

A therapeutic synergistic effect is seen in animal models when vinca alkaloids are administered after methotrexate. To examine further this interaction in clinical studies, a phase I-II trial was conducted in children with hematologic malignancies in the Department of Pediatrics at Memorial Sloan-Kettering Cancer Center. A schedule of sequential of methotrexate and vindesine was developed which showed effect in acute lymphoblastic leukemia in children in relapse and which was relatively nontoxic. The regimen has also been useful for reinduction for patients who are candidates for bone marrow transplant.
