Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This phase I/II trial studies the side effects and best dose of CPX-351 in combination with quizartinib for the treatment of acute myeloid leukemia and high risk myelodysplastic syndrome. CPX-351, composed of chemotherapy drugs daunorubicin and cytarabine, works in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Quizartinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. The goal of this study is to learn if the combination of CPX-351 and quizartinib can help to control acute myeloid leukemia and myelodysplastic syndrome.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

PRIMARY OBJECTIVES:

I. To determine the safety and maximum tolerable dose (MTD) of liposomal cytarabine and daunorubicin (CPX-351) in combination with quizartinib in patients with newly diagnosed or relapsed refractory acute myeloid leukemia (AML) and high-risk myelodysplastic syndrome (HR-MDS).

II. To determine the overall response rate (ORR) rate including CR (complete remission) + CRp (complete remission with incomplete platelet recovery) + CRi (complete remission with incomplete count recovery) + partial remission (PR) within 3 months of treatment initiation of CPX-351 and quizartinib combination.

SECONDARY OBJECTIVE:

I. To assess the overall survival (OS), event-free survival (EFS) and duration of response (DOR) of patients treated with this combination.

EXPLORATORY OBJECTIVES:

I. To evaluate the ORR, EFS (event free survival) and OS (overall survival) in FLT3 mutated/NPM1 wild-type patients versus FLT3 mutated/NPM1 mutated versus FLT3 wild-type/NPM1 mutated patients treated with CPX-351 and quizartinib.

II. Quantitative changes of FLT3-ITD allelic burden and longitudinal evaluation to identify emergence of FLT3 non-ITD mutations with time in patients treated with the combination.

III. To determine the effect of this treatment combination on responding patients transitioning to hematopoietic stem cell transplant (HSCT).

IV. To store and/or analyze surplus blood or tissue including bone marrow, if available, for potential future exploratory research into factors that may influence development of AML and/or response to the combination (where response is defined broadly to include efficacy, tolerability or safety).

OUTLINE: This is a dose-escalation study of CPX-351, followed by a phase II study.

INDUCTION: Patients receive CPX-351 intravenously (IV) over 90 minutes on days 1, 3 and 5 and quizartinib orally (PO) on days 6-19. Patients who do not respond to treatment during cycle 1 receive CPX-351 IV on days 1 and 3 and quixartinib PO on days 6-19 during cycle 2. Treatment repeats every 28 days for up 2 cycles in the absence of disease progression or unacceptable toxicity.

CONSOLIDATION: Patients receive CPX-351 over 90 minutes on days 1 and 3 and quizartinib PO on days 4-28 of cycle 1. Treatment with CPX-351 repeats every 28 days for 2 cycles in the absence of disease progression or unacceptable toxicity.

MAINTENANCE: Patients receive quizartinib PO on days 1-28 in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days, then every 3-6 months for up to 5 years.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Diagnosis of 1) AML (World Health Organization \[WHO\] classification definition of \>= 20% blasts, excluding acute promyelocytic leukemia \[APL\]), or 2) high risk MDS (\> 10% bone marrow blasts)
* For frontline cohort: Patients aged \>= 60 years old
* For relapsed or refractory cohort: Patients aged \>= 18 years old
* For frontline cohort: Patients must be chemonaive, i.e., not have received any chemotherapy (except hydrea or 1-2 doses of ara-C for transient control of hyperleukocytosis) for AML or MDS. They may have received transfusions, hematopoietic growth factors or vitamins for an antecedent hematological disorder (AHD) or for AML. Temporary prior measures such as apheresis, ATRA (all-trans retinoic acid), steroids or hydrea while diagnostic work-up is being performed are allowed and not counted as a prior salvage. Supportive care therapy for MDS (growth factors, transfusions) will not be considered as prior therapy for MDS/AML and these patients will be enrolled to the frontline cohort of the study if they are otherwise eligible
* For relapsed or refractory cohort: Patients who have received at least one prior therapy for AML or for MDS (with \> 10%) blasts will be eligible. Patients may have received up to 4 salvage regimens for AML and/or MDS (defined by the International Prognostic Scoring System \[IPSS\] classification). Patients who receive MDS directed therapies considered not purely supportive such as hypomethylating agents (HMAs), lenalidomide, investigational therapies, will be enrolled to the salvage cohort if they are otherwise eligible
* In the absence of rapidly progressing disease, the interval from prior treatment to time of initiation of protocol therapy will be at least 2 weeks for cytotoxic agents or at least 5 half-lives for cytotoxic/noncytotoxic agents (whichever is shorter). The half-life for the therapy in question will be based on published pharmacokinetic literature (abstracts, manuscripts, investigator brochure's, or drug-administration manuals) and will be documented in the protocol eligibility document. The use of chemotherapeutic or anti-leukemic agents is not permitted during the study with the following exceptions: (1) intrathecal (IT) therapy for patients with controlled central nervous system (CNS) leukemia at the discretion of the principal investigator (PI). (2) Use of cytarabine (up to 2 g/m\^2) or hydroxyurea for patients with rapidly proliferative disease is allowed before the start of study therapy and for the first four weeks on therapy. These medications will be recorded in the case-report form
* Eastern Cooperative Oncology Group (ECOG) performance status =\< 2

* Patients with known significant impairment of gastrointestinal (GI) function or GI disease as determined by the investigator that may significantly alter the absorption of quizartinib
* Patients with any other known concurrent severe and/or uncontrolled medical condition including but not limited to diabetes, cardiovascular disease including hypertension, renal disease, or active uncontrolled infection, which as determined by the investigator could compromise participation in the study. Patients on active antineoplastic or radiation therapy for a concurrent malignancy at the time of screening. Maintenance therapy, hormonal therapy, or steroid therapy for well-controlled malignancy is allowed
* Patients with a known human immunodeficiency virus (HIV) infection (HIV testing is not required prior to enrollment)
* Patients with known positive hepatitis B or C infection by serology, with the exception of those with an undetectable viral load within 3 months.

* Patients who have had any major surgical procedure within 14 days of day 1
* Impaired cardiac function including any of the following: (a) screening electrocardiogram (ECG) with a corrected QT (QTc) \> 450 msec. The QTc interval will be calculated by Fridericia's correction factor (QTcF) at screening and on day 6 prior to the first dose of quizartinib. The QTcF will be derived from the average QTcF in triplicate. If QTcF \> 450 msec on day 6, quizartinib will not be given
