This is a phase IB/II study with a 3+3 dose de-escalation study design. Patients will continue maintenance treatment with CPX-351 for 6 cycles on D1 and D3, as long as patient remains in CR. The dose de-escalation will be one dose given on D1 only, every 28 days pending toxicity. The maximum tolerated dose will be used for the phase II expansion portion of the study.

Female subjects of childbearing potential must have a negative serum pregnancy test upon study entry
Male and female subjects who agree to use highly effective methods of birth control (e.g., condoms, implants, injectables, combined oral contraceptives, some intrauterine devices [IUDs], sexual abstinence, or sterilized partner) during the period of therapy and for at least 6 months after the last dose of study drug

Exclusion Criteria

History of allergic reactions attributed to compounds of similar composition to cytarabine and daunorubicin or liposomal products
History of other malignancies, except
Malignancy treated with curative intent and with no known active disease present for ≥ 3 years before the first dose of study drug and felt to be at low risk for recurrence by treating physician
Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease
Adequately treated carcinoma in situ without evidence of disease
Unresolved toxicities from prior anti-cancer therapy, defined as having not resolved
to Common Terminology Criteria for Adverse Event (CTCAE, version 4.03), grade
≤1, or to the levels dictated in the inclusion/exclusion criteria with the
exception of alopecia

Any uncontrolled active systemic infection
Any life-threatening illness, medical condition, or organ system dysfunction that, in the investigator's opinion, could compromise the subject's safety or put the study outcomes at undue risk
