| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| To evaluate if venetoclax when co-administered with low dose cytarabine (LDAC) improves overall survival (OS) versus LDAC and placebo, in treatment naïve subjects with acute myeloid leukemia (AML). |
|
| E.2.2 | Secondary objectives of the trial |
The secondary objectives of the study are:
• To evaluate if venetoclax when co-administered with LDAC improves complete remission rate (complete remission + complete remission with incomplete marrow recovery, CR + CRi).
• To evaluate if venetoclax when co-administered with LDAC improves event-free survival (EFS).
• To evaluate if venetoclax when co-administered with LDAC improves the proportion of subjects achieving a composite CR (CR + CRi) by the end of Cycle 1.
• To evaluate if venetoclax when co-administered with LDAC reduces fatigue based on patient reported outcome (PRO) assessment Patient Reported Outcomes Measurement Information System (PROMIS), Fatigue Short Form (SF) 7a.
• To evaluate if venetoclax when co-administered with LDAC improves subjects Global Health Status/Quality of Life (GHS/QoL) based on the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core (EORTC QLQ-C30).

|
| E.4 | Principal exclusion criteria |
• Subject has received any prior treatment for AML with the exception of hydroxyurea, allowed through the first cycle of study treatment. Note: Prior treatment for Myelodysplastic Syndrome is allowed except for use of cytarabine.
• Subject had an antecedent myeloproliferative neoplasm (MPN) including myelofibrosis, essential thrombocytosis, olycythemia vera, or chronic myelogenous leukemia (CML) with or without BCR-ABL mutation.
• Subjects that have acute promyelocytic leukemia (APL).
• Subject has known CNS involvement with AML.
• Subject has known HIV infection (due to potential drug-drug interactions between antiretroviral medications and venetoclax).
• Subject is known to be positive for hepatitis B virus (HBV), or hepatitis C virus (HCV) infection. Inactive hepatitis carrier status or low viral hepatitis titer on antivirals (non-exclusionary medications) are not excluded.
• Subject has received strong or moderate CYP3A inducers 7 days prior to the initiation of study treatment.
• Subject has consumed grapefruit, grapefruit products, Seville oranges (including marmalade containing Seville oranges) or Star fruit within 3 days prior to the initiation of study treatment.
• Subject has cardiovascular disability status of New York Heart Association Class > 2. Class 2 is defined as cardiac disease which subjects are comfortable at rest but ordinary physical activity results in fatigue, palpitations, dyspnea, or angina pain.
• Subject has chronic respiratory disease that requires continuous oxygen, or significant history of renal, neurologic, psychiatric, endocrinologic, metabolic, immunologic, hepatic, cardiovascular disease, or any other medical condition that in the opinion of the investigator would adversely affect his/her participating in this study.
• Subject has a malabsorption syndrome or other condition that precludes enteral route of administration.
• Subject exhibits evidence of other clinically significant uncontrolled systemic infection requiring therapy (viral, bacterial or fungal).
• Subject has a history of other malignancies prior to study entry, with the exception of:
- Adequately treated in situ carcinoma of the cervix uteri or carcinoma in situ of breast;
- Basal cell carcinoma of the skin or localized squamous cell carcinoma of the skin;
- Previous malignancy confined and surgically resected (or treated with other modalities) with curative intent.
