Description of intervention(s) / exposure
Treatment: Drugs - Cytarabine
Treatment: Drugs - Idasanutlin
Other interventions - Placebo
Experimental: Idasanutlin plus Cytarabine - Participants will receive induction therapy idasanutlin and cytarabine for 5 Days followed by 23 days of rest in Cycle 1 (treatment cycle length=28 days). Responding participants may continue with consolidation therapy for a maximum of 2 additional cycles including idasanutlin and cytarabine for 5 days followed by 23 days of rest in each cycle (treatment cycle length=28 days). After each cycle, for participants achieving CRp or complete remission with incomplete blood count recovery (CRi), up to 28 additional days are allowed for blood count recovery, if needed.
Placebo comparator: Placebo plus Cytarabine - Participants will receive induction therapy idasanutlin matching placebo and cytarabine for 5 days followed by 23 days of rest in Cycle 1 (treatment cycle length=28 days). Responding participants may continue with consolidation therapy for a maximum of 2 additional cycles including idasanutlin matching placebo and cytarabine for 5 days followed by 23 days of rest in each cycle (treatment cycle length=28 days). After each cycle, for participants achieving CRp or CRi, up to 28 additional days are allowed for blood count recovery, if needed.
Treatment: Drugs: Cytarabine
Participants will receive cytarabine 1 gram per square meter (g/m\^2) intravenous (IV) infusion for 5 days of every treatment cycle.
Treatment: Drugs: Idasanutlin
Participants will receive idasanutlin 300 mg per oral (PO) twice daily (BID) (in Cycle 1) or once daily (QD) (in Cycles 2 and 3) for 5 days of every treatment cycle.
Other interventions: Placebo
Participants will receive idasanutlin matching placebo PO BID or QD for 5 days of every treatment cycle.

P53 tumor protein Wild Type (TP53 WT) population's Overall Survival was compared in participants with relapsed or refractory (R/R) acute myeloid leukemia (AML) who had been randomized to idasanutlin in combination with cytarabine versus those who had been randomized to cytarabine and placebo.
The study was terminated because of futility, therefore did not reach the planned end of the study.

Laboratory parameters for blood biochemistry will be measured and compared with a standard reference range. Values outside the standard reference range are considered abnormalities. A laboratory test result will be reported as an adverse event if it meets any of the following criteria: is accompanied by clinical symptoms; results in a change in study treatment or a medical intervention; or is clinically significant in the investigator's judgment.
For each patient, baseline is the last observation prior to initiation of study drug. For each laboratory test, patients with at least 1 post-baseline assessment are included in the analysis. For each cell, the denominator is the number of patients with baseline NCI-CTCAE Grade 0-2 in the specified direction of abnormality, or Grade 1-4 in the opposite direction of abnormality.

The Total Clearance (CL) of Cytarabine was planned as part of the PK analyses. The Independent Data Monitoring Committee recommended stopping the study for futility based on a lack of OS benefit due to Hazard Ratio (HR) being greater than 1. The benefit-risk profile of idasanutlin combined with 1g/m2 cytarabine in fit R/R AML was not positive, as the observed marginal benefit does not outweigh the risks of idasanutlin in the relapsed or refractory AML population.
Therefore the study was prematurely terminated by the sponsor's decision and the result data did not derive.

The compliance rate (defined as the number of patients who completed as least 1 question on the measure) at baseline was 56% and 61% for the Idasanutlin arm and the placebo arm, respectively. This compliance rate remained the same post-baseline in both arms. Due to the low compliance rates in both arms during the entire treatment period, the planned analyses were not performed.

Summary
Brief summary
This is a multicenter, double-blind, randomized, placebo-controlled study designed to compare overall survival in participants with relapsed or refractory AML treated with idasanutlin in combination with cytarabine versus participants treated with placebo and cytarabine. Participants will receive induction treatment with idasanutlin/placebo and cytarabine (Cycle 1). Responding participants may continue to receive a maximum of further two cycles of consolidation (Cycle 2 and Cycle 3). Complete remission (CR), CR with incomplete platelet count recovery (CRp), overall remission rate (ORR), event-free survival (EFS) and percentage of participants with an allogeneic hematopoietic stem cell transplant (HSCT) will also be compared between treatment arms. This study will include participants with and without TP53 wild type (TP53 WT) mutations.
