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

Korábbi kezelés

• 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.
• Eligible for intensive chemotherapy and/or allogeneic stem cell transplantation.
  • The reason a patient is not eligible for intensive chemotherapy and/or allogeneic stem cell transplantation is described in the inclusion criteria section
  • The reason a patient is not eligible for intensive chemotherapy must be documented in the electronic case report form (eCRF).
• 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.
• 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).
• 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).
• 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.
• Treatment with strong Cytochrome P450, family 3, subfamily A (CYP3A) inducers (see Appendix 8) within 14 days before the first dose of pevonedistat.
• 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.
• Systemic antineoplastic therapy for malignant conditions other than myeloid neoplasms within 14 days before the first dose of any study drug.

Más betegség

• Patients with uncontrolled coagulopathy or bleeding disorder.
• 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.
