A Phase II Study of the Aurora A Kinase Inhibitor Alisertib in Combination With 7+3 Induction Chemotherapy in Patients With High-risk Acute Myeloid Leukemia
A Phase II Study of the Aurora A Kinase Inhibitor Alisertib in Combination With 7+3 Induction Chemotherapy in Patients With High-risk Acute Myeloid Leukemia
This research study is studying a targeted therapy (a form of treatment that uses drugs or other substances to identify and attack specific types of cancer cells with less harm to normal cells) as a possible treatment for high-risk acute myeloid leukemia.
The names of the study interventions involved in this study are:
This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational intervention to learn whether the intervention works in treating a specific disease. "Investigational" means that the intervention is being studied.
As part of this research study, the participant will take alisertib in combination with conventional chemotherapies, idarubicin and cytarabine. Alisertib has not been approved by the FDA (U.S. Food and Drug Administration) for acute myeloid leukemia (AML). However, cytarabine and idarubicin have both been approved by the FDA for treatment of AML. It also means that the FDA (U.S. Food and Drug Administration) has not approved giving alisertib with idarubicin and cytarabine for use in participants, including participants with this type of cancer.
Earlier pre-clinical studies and clinical trials have suggested the alisertib may have clinical promise as a single agent in acute myeloid leukemia. Alisertib is a selective small molecule inhibitor of Aurora A kinase, an enzyme which may play a role in the survival of leukemia cells. Alisertib is being studied for the treatment of advanced malignancies, including AML. Essentially, this means that alisertib may work to halt the growth of malignancy (abnormal cells dividing without control and invading nearby tissues) through a targeted mechanism. By combining alisertib with standard chemotherapy, the hope is to enhance the efficacy of current treatment used for acute myeloid leukemia. An earlier study of this combination has completed accrual, and demonstrated that the regimen is well tolerated.
Through this study, the investigators would like to determine if the addition of alisertib to standard 7+3 chemotherapy improves efficacy as measured by the rate of complete remission (a decreased or disappearance of signs and symptoms of cancer).
Inclusion Criteria:
Participants must have pathologically confirmed, newly diagnosed high-risk acute myeloid leukemia, as defined by at least one of the following criteria
Adults, age 18 years or older at the time of diagnosis, eligible for standard induction chemotherapy according to their treating physician.
ECOG performance status 0-2 (Karnofsky ≥60%, see Appendix A)
Left ventricular ejection fraction > 50% as measured by echocardiogram or MUGA scan
Must not have received systemic antineoplastic therapy including radiation therapy within 14 days of the study enrollment, except hydroxyurea or 6-mercaptopurine for the purposes of cytoreduction. Patients may also have received all-trans retinoic acid (ATRA) if there is an early suspicion of acute promyelocytic leukemia (APL, M3-AML), although if confirmed to have APL these patients will be excluded from the study.
Adequate renal function as defined by: calculated creatinine clearance ≥40 mL/min (Cockcroft-Gualt Formula)
Direct bilirubin < 2.0 x upper limit of normal (ULN), SGOT (AST) and SGPT (ALT)< 2.5 x ULN. AST and/or ALT may be up to 5X ULN if thought to be secondary to leukemia.
The effects of alisertib on the developing human fetus are unknown. For this reason and because other chemotherapeutic agents are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception for the duration of study participation, and 6 months after completion of therapy.
Subject must be able to take oral medication and to maintain a fast as required for 2 hours before and 1 hour after alisertib administration.
Ability to understand and the willingness to sign a written informed consent document.
Exclusion Criteria:
Patients will be excluded from this study if they do not otherwise fulfill criteria mentioned in bullet 3.1.1, and are found to harbor "intermediate" or "favorable" risk cytogenetics 41:
In such patients, a sample to evaluate patient cytogenetics will be sent at the time of diagnosis per standard clinical care and the absence of favorable or intermediate-risk cytogenetics must be confirmed by Day 8. If the cytogenetic analysis reveals that the patient harbors non-poor risk cytogenetics, or if the cytogenetic results are not received prior to Day 8, the participant will be removed from the study.
Patients with acute bilineal/biphenotypic leukemia
Participants who have had chemotherapy or radiotherapy within 14 days prior to entering the study, except for hydroxyurea or 6-MP as noted.
Participants who are receiving or have received any other investigational agents within 14 days of enrollment.
Chemo-, hormono-, radio- or immunotherapy or therapy with monoclonal antibodies or small tyrosine kinase inhibitors within the past 4 weeks prior to treatment with the trial drug
Persistence of clinically relevant therapy related toxicity from previous anti-cancer therapy
Prior allogeneic bone marrow or organ transplantation
Individuals with a history of a different malignancy are ineligible except for the following circumstances. Individuals with a history of other malignancies are eligible if they have been disease-free for at least 5 years and are deemed by the investigator to be at low risk for recurrence of that malignancy. Individuals with the following cancers are eligible if diagnosed and treated within the past 5 years: cervical cancer in situ, and basal cell or squamous cell carcinoma of the skin.
Current clinical central nervous system (CNS) symptoms deemed by the investigator to be related to leukemic CNS involvement (no lumbar puncture required, clinical assessment per investigator's judgment is sufficient).
If applicable, patient with ≥Grade 2 peripheral neuropathy within 14 days before enrollment
Prior treatment with alisertib
Known history of hepatitis C infection or suspected currently active hepatitis C infection. Known or suspected history of hepatitis B infection will be excluded when any of the following conditions are met:
Current or history of congestive heart failure New York Heart Association (NYHA) class 3 or 4, or any history of documented diastolic or systolic dysfunction (LVEF <50%, as measured by MUGA scan or echocardiogram). Prior to study entry, any ECG abnormality at screening has to be documented by the investigator as not medically relevant
Known hypersensitivity to the trial drugs or other contraindication to standard "7+3" induction chemotherapy.
Known history of uncontrolled sleep apnea syndrome, or sleep apnea requiring supplemental oxygen, and other conditions that could result in excessive daytime sleepiness.
A medical condition requiring use of proton pump inhibitors (PPIs); or histamine 2 (H2) receptor antagonists. Patients who intermittently use these medications, must meet the following criteria:
Patients with mental deficits or psychiatric conditions that preclude them from giving informed consent or following protocol.
Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection requiring intravenous antibiotics, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
Known GI disease or GI procedures that could interfere with the oral absorption or tolerance of alisertib. Examples include, but are not limited to partial gastrectomy, history of small intestine surgery, and celiac disease.
Pregnant women are excluded from this study because alisertib, along with standard induction chemotherapy, carries the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with alisertib as well as cytarabine and idarubicin, breastfeeding should be avoided. Confirmation that the subject is not pregnant must be established by a negative serum ß-human chorionic gonadotropin ( ß-hCG) pregnancy test result obtained during screening. Pregnancy testing is not required for post-menopausal or surgically sterilized women.
Although not absolute exclusion criteria, because of known drug-drug interactions, below are issues that should be considered during enrollment:
Treatment with clinically significant enzyme-inducing drugs, including known P-glycoprotein inducers (including St John's wort and rifampicin) should be used only if absolutely necessary and considered to be the best available choice for the patient. If possible, it is recommended that alternatives to known substrates, inhibitors or inducers of P-glycoprotein be considered. Cases should be discussed with the principal investigator, and may be allowed as per his/her discretion.
