Study to Compare Azacitidine Plus Pevonedistat Versus Azacitidine in Patients With Acute Myeloid Leukemia Not Eligible for Standard Chemotherapy

Study Overview
=================
Brief Summary
-----------------
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.

Detailed 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

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.

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.
