Brief Summary

This phase 2 clinical trial will evaluate the effectiveness and safety of fludarabine in combination with CPX-351 in patients with untreated AML. Patients will receive fludarabine and CPX-351 during Induction 1 and 2 as well as 2 cycles of consolidation therapy.

Detailed Description

This is a phase 2, open label single arm study to look at the effectives and safety of fludarabine in combination with CPX-351 in patients with untreated AML. The rationale for this combination stems from data which indicated that pre-treatment of the THP-1 cell line with fludarabine for 4 hours prior to CPX-351 administration (Flu-CPX) significantly potentiated intracellular ara-CTP accumulation compared to CPX-351 alone. This suggests that fludarabine combined with CPX-351 may have efficacy against leukemic clones that would be resistant to CPX-351 or standard chemotherapy in first induction. It has been demonstrated that treatment with CPX-351 produces superior clinical outcomes in secondary AML likely due to its novel formulation, which results in sustained exposure of the cytotoxic agents cytarabine and daunorubicin in a synergistic 5:1 ratio within the plasma and bone marrow. Fludarabine can potentially improve upon the outcomes observed with CPX-351 monotherapy and 7+3 by enhancing intracellular ara-CTP accumulation from CPX-351. Patients will received fludarabine and CPX-351 for up to 2 cycles of induction and 2 cycles of consolidation.

8. Women of child-bearing potential and men with partners of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 120 days following completion of therapy. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.

9. Women of child-bearing potential has negative pregnancy test prior to initiating study drug dosing.

Exclusion Criteria

1. Current or anticipated use of additional investigational agents.

2. Any prior treatment for AML with the exception of corticosteroids, hydroxyurea, and/or leukapheresis to prevent or treat early complications prior to starting study therapy. Permitted prior therapy must be stopped 24 hours prior to starting study therapy.
