Eligibility criteria
Inclusion
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
Serum biochemical values with the following limits unless considered due to leukemia
Creatinine \< 1.8 mg/dl
Total bilirubin \< 1.8 mg/dL, unless increase is due to hemolysis or congenital disorder
Transaminases (serum glutamate pyruvate transaminase \[SGPT\]) \< 2.5x upper limit of normal (ULN)
Potassium, magnesium, and calcium (normalized for albumin) levels should be within institutional normal limits
Ability to take oral medication
Ability to understand and provide signed informed consent
Baseline left ventricular ejection fraction by echocardiogram (ECHO) or multigated acquisition scan (MUGA) \>= 50%
Women of childbearing potential (WOCBP) must have a negative serum or urine pregnancy test within 7 days. Men must agree not to father a child and agree to use a condom if his partner is of child bearing potential
WOCBP must use appropriate method(s) of contraception. WOCBP should use an adequate method to avoid pregnancy until at 30 days after the last dose of investigational drug. Women who are not of childbearing potential (ie, who are postmenopausal or surgically sterile) as well as men with azoospermia do not require contraception. Appropriate methods of birth control include: birth control pills, condoms, intrauterine device (IUD), or other Food and Drug Administration (FDA) approved birth control methods
Patients may be concurrently enrolling in supportive care clinical trials. Other investigational agents that are used for treatment of other cancers will not be allowed
Exclusion
Patients with known allergy or hypersensitivity to quizartinib, mannitol, CPX-351 or any of their components
Patients with electrolyte abnormalities at study entry defined as follows: (a) Serum potassium \< 3.5 mEq/L despite supplementation, or \> 5.5 mEq/L. (b) Serum magnesium above or below the institutional normal limit despite adequate management. (c) Serum calcium (corrected for albumin levels) above or below institutional normal limit despite adequate management
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. (Hepatitis B or C testing is not required prior to study entry). Subjects with serologic evidence of prior vaccination to hepatitis B virus (HBV) (i.e., hepatitis surface antigen \[HBs Ag\]-, and anti-HBs+) may participate
Patients who have consumed grapefruit, grapefruit products, Seville oranges (including marmalade containing Seville oranges) within 3 days prior to the initiation of study treatment
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
Patients with congenital long QT syndrome
History or presence of sustained ventricular tachycardia requiring medical intervention
Any history of clinically significant ventricular fibrillation or torsades de pointes
Known history of second or third degree heart block (may be eligible if the patient currently has a pacemaker)
Sustained heart rate of \< 50/minute on pre-entry ECG
Right bundle branch block + left anterior hemiblock (bifascicular block)
Complete left bundle branch block
Patients with myocardial infarction or unstable angina within 6 months prior to starting study drug
Congestive heart failure (CHF) New York (NY) Heart Association class III or IV
Atrial fibrillation documented within 2 weeks prior to first dose of study drug
Patients who are actively taking a strong CYP3A4 inducing medication
Patients who require treatment with concomitant drugs that prolong QT/QTc interval with the exception of antibiotics, antifungals, and antivirals that are used as standard of care to prevent or treat infections and other such drugs that are considered absolutely essential for the care of the subject or if the Investigator believes that beginning therapy with a potentially QTc-prolonging medication (such as anti-emetic) is vital to an individual subject's care while on study
Known family history of congenital long QT syndrome
What this trial measures
- Maximum tolerated doseUp to 28 days
Will follow standard reporting guidelines for adverse events, and summarize safety data by category, severity and frequency.
- Complete remission (CRc) rateUp to 3 cycles (28 days in 1 cycle)
CRc and toxicity will be monitored simultaneously using the Bayesian approach of Thall, Simon, Estey (1995) as extended by Thall and Sung (1998). Will estimate the CRc rate for the combination treatment, along with the 95% credible interval.
