Tailored chemo dosing shows promise for adult leukemia

NCT ID NCT00136435

First seen Jun 27, 2026 ยท Last updated Jun 27, 2026

Summary

This phase II study tested a personalized dosing approach for the chemotherapy drug L-asparaginase in 100 adults aged 18-50 with newly diagnosed acute lymphoblastic leukemia (ALL). The goal was to see if adjusting doses based on individual drug levels could help more patients complete all 30 planned doses safely. Participants also received other standard chemotherapy drugs. The study measured how many patients finished the full course of L-asparaginase and tracked disease-free survival over four years.

Active substance
L-asparaginase
What this could lead to
If successful, this could lead to a safer and more effective way to give L-asparaginase to adults with ALL, potentially improving survival rates.
What could go wrong
This is a phase II trial with only 100 participants, so results may not apply to all patients. The treatment involves multiple chemotherapy drugs with known side effects like infection and organ damage.
