Korábbi kezelés

• Previous exposure of anthracycline ≥ 550 mg/m² (Daunorubicin equivalence)
• Previous AML treatment other than Hydroxyurea
• Treatment with an investigational drug within 30 days or 5 half-life whichever is longer, preceding the initiation study and/or previous treatment with Venetoclax
• Other comorbidity that the physician judges to be incompatible with conventional intensive chemotherapy which must be reviewed and approved by the study medical monitor before study enrolment
• Subjects must have received intensive induction by Idarubicin, Cytarabine and Lomustine
• Male subjects who are sexually active must agree, from study Day 1 through at least 180 days after the last dose of study drug, to practice protocol-specified methods of contraception
• Treatment with any of the following within 7 days prior to the first dose of study drug :
  • Strong or moderate CYP3A inducers
  • Steroid therapy for anti-neoplastic intent
• Subject having consumed grapefruit, grapefruit products, Seville oranges (including marmalade containing Seville oranges) or Star fruit within 3 days prior to the initiation of study treatment.

Más betegség

• History of another malignancy within the past 3 years except basal cell carcinoma of the skin or cervix in situ carcinoma
• Subject with known HIV infection (due to potential drug-drug interactions between antiretroviral medications and Venetoclax). HIV testing will be performed at Screening. Subject known to be positive for hepatitis B virus (HBV) or hepatitis C virus (HCV) infection. Inactive hepatitis carrier status with undetectable Polymerase Chain Reaction (PCR) viral load on antivirals (non-exclusionary medications) are not excluded.
  • Randomization criteria:
• Patient in Partial Remission (PR) or failure following one induction course by Idarubicin, Cytarabine and Lomustine (according ELN 2017 criteria)
• Uncontrolled infection
• Subject with cardiovascular disability status as per New York Heart Association Class > 2. Class 2 is defined as cardiac disease in which subjects are comfortable at rest but ordinary physical activity results in fatigue, palpitations, dyspnea, or angina pain. Class 3 is defined as cardiac disease in which subjects are comfortable at rest but less than ordinary activity causes fatigue, palpitation, or dyspnea. Class 4 is defined as cardiac disease in which subjects have an inability to carry on any physical activity without discomfort, symptoms of heart failure at rest, and if any physical activity is undertaken then discomfort increases.
• Subject has a malabsorption syndrome or other condition that precludes enteral route of administration.
• Subject having chronic respiratory disease that requires continuous oxygen, or a 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.
• Known hypersensitivity to the study medication

  • Alanine aminotransferase (ALT) ≤ 3.0 × ULN
  • Bilirubin ≤ 1.5 × ULN
• Adequate cardiac function with LVEF ≥ 50 %
• Any serious medical condition, laboratory abnormality, or psychiatric illness that would place the participant at an unacceptable risk or prevent them from giving informed consent.
