About
Randomized phase III, multicentre, open label clinical trial to compare pevonedistat in combination with azacytidine versus azacytidine alone, which can be considered a standard of care for patients with newly diagnosed acute myeloid leukemia not eligible for intensive chemotherapy (thus not eligible for an allogeneic hematopoietic stem cell transplant.
Full description
Prospective, 1:1 randomized multicentre, open label, phase III clinical trial to evaluate efficacy and safety of pevonedistat in combination with azacytidine versus azacytidine in the treatment of naïve adult patients with acute myeloid leukemia who are not eligible for standard induction therapy due to age, co-morbidities or risk-factors.
Subjects will be randomized to one of the two treatment arms in a 1:1 ratio, both of which will have treatment cycles of 28 days:
Arm A: Pevonedistat (PEVO) 20 mg/m2 IV on days 1, 3, and 5 plus Azacitidine (AZA) 75 mg/m2 subcutaneous (SC) administered on a 5-on/2-off [weekend]/2-on schedule in 28-day cycles (IV AZA can be administered for any patients who have non-tolerated local reactions)
Arm B: AZA 75 mg/m2 SC on a 5-on/2-off [weekend]/2-on schedule in 28-day cycle (IV AZA can be administered for any patients who have non-tolerated local reactions)
466 subjects will be randomized in the study. Subjects will continue their study treatment until documented disease progression per Investigator assessment, unacceptable toxicity, withdrawal of consent, or the subject meets other protocol criteria for discontinuation

Inclusion criteria
Male or female patients 18 years or older
Morphological diagnosis of Acute Myeloid Leukemia (AML) (WHO criteria 2008)
Subject must have an Eastern Cooperative Oncology Group (ECOG) Performance status (PS) of 0 to 3 (ECOG 0-2 for patients greater than or equal to 75 years old).
Newly diagnosed AML
Patient must be considered be ineligible for treatment with a standard Ara-C and anthracycline induction regimen due to age or co-morbidities defined by one of the following:
≥ 75 years of age
Or ≥ 18 to 74 years of age with at least one of the following:
Clinical laboratory values within the following parameters (repeat within 3 days before the first dose of study drug if laboratory values used for randomization were obtained more than 3 days before the first dose of study drug):
Subject has a white blood cell count <50 × 109/L. Patients who are cytoreduced with leukapheresis or with hydroxyurea may be enrolled if they meet the eligibility criteria before starting therapy.
Female subjects must be either postmenopausal for at least 1 year before screening (see Appendix 12 for definition) OR permanently surgical sterile (bilateral oophorectomy, bilateral salpingectomy or hysterectomy) OR Women of Childbearing Potential (WOCBP) must agree to practice 1 highly effective method and 1 additional effective (barrier) method of contraception (see Appendix 11), at the same time, from the time of signing the informed consent through 4 months after the last dose of study drug (female and male condoms should not be used together), or Agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of the subject. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, postovulation methods] withdrawal, spermicides only, and lactational amenorrhea are not acceptable methods of contraception). Female subjects of childbearing potential must have negative results for pregnancy test performed and must not be lactating and breastfeeding.
Male subjects even if surgically sterilized (i.e., status post vasectomy), who are sexually active, must agree, from Study Day 1 through at least 4 months after the last dose of study drug, to practice effective barrier contraception during the entire study treatment period and through 4 months after the last dose of study drug (female and male condoms should not be used together), or agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of the subject. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, postovulation methods for the female partner] withdrawal, spermicides only, and lactational amenorrhea are not acceptable methods of contraception.)
Subject must voluntarily sign and date an informed consent, approved by an Independent Ethics Committee (IEC)/Institutional Review Board (IRB), prior to the initiation of any screening or study specific procedures, with the understanding that consent may be withdrawn by the patient at any time without prejudice to future medical care.
Exclusion criteria
Previous treatment for myelodysplastic síndrome (MDS) or Chronic Myelomonocytic Leukemia (CMML) or myeloproliferative neoplasms (MPN), with chemotherapy or other antineoplastic agents including HMAs (up to 2 cycles of Hypomethylating agents (HMA) such as decitabine or azacitidine. Previous treatment is permitted with hydroxyurea and with lenalidomide, except that lenalidomide may not be given within 8 weeks before the first dose of study drug.
Subject has history MPN with BCR-ABL1 translocation and AML with BCR-ABL1 translocation.
Genetic diagnosis of acute promyelocytic leukemia.
Eligible for intensive chemotherapy and/or allogeneic stem cell transplantation.
Patients with either clinical evidence of or history of central nervous system involvement by AML.
Diagnosed or treated for another malignancy within 1 year before randomization or previously diagnosed with another malignancy and have any evidence of residual disease which may compromise the administration of AZA or AZA+PEVO.
Psychological,social, or geographic factors that otherwise preclude the patient from giving informed consent, following the protocol, or potentially hamper compliance with study treatment and follow-up.
Subject has a white blood cell count > 50 × 109/L.
Contraindications for PEVO or AZA.
Known hypersensitivity to pevonedistat or its excipients.
Female patients who intend to donate eggs (ova) during the course of this study or for 4 months after receiving their last dose of study drug(s).
Female patients who are both lactating and breastfeeding or have a positive serum pregnancy test during the screening period or a positive urine pregnancy test on Day 1 before first dose of study drug.
Male patients who intend to donate sperm or father a child during the course of this study or for 4 months after receiving their last dose of study drug(s).
Subject is known to be positive for HIV (HIV testing is not required for eligibility assessment). Known HIV positive patients who meet the following criteria will be considered eligible:
Subject is known to be positive for hepatitis B or C infection, with the exception of those with an undetectable viral load within 3 months (Hepatitis B or C testing is not required for eligibility assessment).
Known hepatic cirrhosis or severe preexisting hepatic impairment.
Patients with the following will be excluded: uncontrolled intercurrent illness including, but not limited to known cardiopulmonary disease defined as unstable angina, clinically significant arrhythmia, congestive heart failure (New York Heart Association Class III or IV; see Appendix 7), and/or ST elevation myocardial infarction within 6 months before first dose, or severe symptomatic pulmonary hypertension requiring pharmacologic therapy, severe uncontrolled ventricular arrhythmias, or electrocardiographic evidence of acute ischemia or active conduction system abnormalities. As an example, well-controlled atrial fibrillation would not be an exclusion whereas uncontrolled atrial fibrillation would be an exclusion. Patients with medical comorbidities that will preclude safety evaluation of the combination should not be enrolled.
Subject has chronic respiratory disease that requires continuous oxygen, or significant history of renal, neurologic, psychiatric, endocrinologic, metabolic, immunologic, hepatic, cardiovascular disease, any other medical condition that in the opinion of the investigator would adversely affect his/her participating in this study.
Treatment with strong Cytochrome P450, family 3, subfamily A (CYP3A) inducers (see Appendix 8) within 14 days before the first dose of pevonedistat.
Patients with uncontrolled coagulopathy or bleeding disorder.
High blood pressure which cannot be controlled by standard treatments
Prolonged rate corrected QT (QTc) interval ≥ 500 msec, calculated according to institutional guidelines.
As infection is a common feature of AML, patients with active infection are permitted to enroll provided that the infection is under control and no signs of systemic inflammatory response beyond low grade fever that makes patient clinically unstable in the opinion of the investigator. Patients with uncontrolled infection shall not be enrolled until infection is treated and brought under control.
Patients who have received an investigational agent (for any indication) within 5 half-lives of the agent and until toxicity from this has resolved to grade 1 or less; if the half-life of the agent is unknown, patients must wait 4 weeks prior to first dose of study treatment.
