Wee1 Kinase Inhibitor AZD1775 and Combination Chemotherapy in Treating Children, Adolescents and Young Adults With Relapsed or Refractory Acute Myeloid Leukemia

• Status: Withdrawn
• Trial end date: 2019-05-31
• Target enrollment: 0
• Participant gender: All

Summary

This phase I trial studies the side effects and best dose of wee1 kinase inhibitor AZD1775 when given together with fludarabine, cytarabine, and filgrastim (FLAG) combination chemotherapy in treating children, adolescents and young adults with relapsed or refractory acute myeloid leukemia. Wee1 kinase inhibitor AZD1775 may help combination chemotherapy work better by making tumor cells more sensitive to the drugs. Drugs used in chemotherapy, such as fludarabine and cytarabine, may prevent tumor cells from multiplying by damaging their deoxyribonucleic acid (DNA), which in turn stops the tumor from growing. Giving wee1 kinase inhibitor AZD1775 and FLAG chemotherapy may work better in treating patients with acute myeloid leukemia.
