  • Previous pulmonary embolism within 12 months before study entry
  • Uncontrolled hypertension defined as systolic blood pressure >160 mmHg or diastolic blood pressure >100 mmHg, despite optimal medical management and stable antihypertensive treatment for more than 7 days before the first dose of study drug
  • Moderate or severe hepatic impairment, i.e. Child-Pugh class B or C
  • Known history of human immunodeficiency virus (HIV) infection
  • Chronic or active hepatitis B or C, requiring antiviral therapy
  • Serious, uncontrolled infection requiring systemic antibiotic, antifungal or antiviral therapy
  • Uncontrolled meningeal leukemia
  • Prior allogeneic hematopoietic stem cell transplant within </=4 months before first dose of study drug (Subjects must have completed immunosuppressive therapy before enrollment.

Treatment and study plan

Atuveciclib, BAY1143572

Drug

The starting dose was 20 mg BAY 1143572 once daily from Cycle 1 Day 1. Each cycle was defined as a period of 28 days. Dosing cycles continued until evidence of progression, unacceptable toxicity, consent withdrawal, or withdrawal from the study at the discretion of the investigator.

Primary outcomes

  1. Maximum Tolerated Dose (MTD) of BAY1143572 in Advanced Acute Leukemia Subjects

    Time frame: After the first 28 days of treatment (cycle 1)

    The MTD was defined as the highest dose that could be given such that not more than 20% of subjects experience a dose limiting toxicity (DLT) during Cycle 1. The study was terminated prior to the determination of MTD and hence no data was presented.

  2. Maximum Total Observed Drug Concentration (Cmax) of BAY1143572 after Single Dose Administration in Plasma

    Time frame: Pre-dose up to 24 hours post-dose on Cycle1 Day 1

    Maximum total observed drug concentration of BAY1143572 after single dose administration in plasma was measured.

  3. Maximum Total Observed Drug Concentration of BAY1143572 after Multiple Dose Administration in Plasma (Cmax,md)

    Time frame: Pre-dose up to 24 hours post-dose on Cycle 1 Day 15

    Maximum total observed drug concentration of BAY1143572 after multiple dose administration in plasma was measured.

  4. Area Under the Concentration Versus Time Curve from Zero to 24 hours (AUC[0-24h]) of BAY1143572 in Plasma After Single Dose Administration

    Time frame: Pre-dose up to 24 hours post-dose on Cycle1 Day 1

    Area under the concentration versus time curve from zero to 24 hours of BAY1143572 in plasma after single dose administration was measured.

  5. Area Under the Concentration Versus Time Curve from Zero to 24 hours of BAY1143572 in Plasma after Multiple Dose Administration (AUC[O-24h]md)

    Time frame: Pre-dose up to 24 hours post-dose on Cycle 1 Day 15

    Area under the concentration versus time curve from zero to 24 hours of BAY1143572 in plasma after multiple dose administration was measured.

  6. Area Under the Concentration Versus Time Curve from Zero to Last Data Point Greater than Lower Limit of Quantitation (LLOQ) of BAY1143572 in Plasma (AUC[0-tlast]) after Single Dose Administration

    Time frame: Pre-dose up to 24 hours post-dose on Cycle 1 Day 1

    Area under the concentration versus time curve from zero to last data point greater than lower limit of quantitation of BAY1143572 in plasma after single dose administration was measured.

  7. Time to Reach Maximum Drug Concentration (tmax) of BAY1143572 in Plasma after Single Dose Administration

    Time frame: pre-dose up to 24 hours post-dose on Cycle 1 Day 1

    Time to reach maximum drug concentration of BAY1143572 in plasma after single dose administration was measured.

  8. Time to Reach Maximum Drug Concentration of BAY1143572 in Plasma after Multiple Dose Administration (tmax,md)

    Time frame: Pre-dose up to 24 hours post-dose on Cycle 1 Day 15

    Time to reach maximum drug concentration of BAY1143572 in plasma after multiple dose administration was measured.

Secondary outcomes

  1. Number of Subjects With Leukemia Response

    Time frame: From start of treatment of the first subject until 28 days

    Bone marrow aspirates / biopsies / peripheral whole blood were taken and assessed for leukemia response evaluation. Assessment of response was made based on the revised recommendations of the International Working Group (Cheson 2003 criteria). Criteria proposed by Cheson 2003 for leukemia: complete remission (CR), morphological CR with incomplete blood count recovery (CRi), partial remission (PR), no response / treatment failure, relapse from CR, CRi, or PR.

  2. Number of Subjects with Treatment Emergent Adverse Events (TEAEs) and Treatment Emergent Serious Adverse Events (TESAEs)

    Time frame: From start of study drug administration up to 30 days after the last dose of study drug administration (approximately 2.5 years)

    An adverse event (AE) was any untoward medical occurrence in subject who received study drug without regard to possibility of causal relationship. AEs that started or worsened after first administration of study medication up to 30 days after end of treatment with study medication were considered to be treatment emergent (TE). A serious adverse event (SAE) was an AE resulting in any of following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly and another medical important serious event as judged by investigator. SAEs that started or worsened after study drug treatment were recorded as TESAEs.

  3. Area Under the Concentration Versus Time Curve from Zero to Infinity (AUC) of BAY1143572 after Single Dose Administration in Plasma

    Time frame: Pre-dose up to 24 hours post-dose on C1D1

    Area under the concentration versus time curve from zero to infinity of BAY1143572 after single dose administration in plasma was measured.
