Original Secondary Outcome Measures  ICMJE Same as current
Current Other Pre-specified Outcome Measures
 (submitted: August 10, 2020)
  • Composite of PK parameters of VEN and PIT summarized by PIT dose level [ Time Frame: Samples will be collected at the following timepoints: Pre-VEN dose during screening, Cycle 1 Day 1 Pre-VEN and PIT dose, Cycle 1 Day 1 Post dose sampling at 1, 2, 4, 8, 24 hours after first PIT dose. Each cycle is 28 days. ]
    Change in PK parameters from baseline to Cycle 1 to determine if concomitant administration of PIT affects concentrations of VEN when given in combination with PIT.
  • Composite of dynamic BH3 profiling in priming of ex vivo AML and CLL specimens [ Time Frame: Samples will be collected for BH3 profiling at the following timepoints: prior to initiation of VEN treatment, Cycle 1 Day 1 Pre-PIT dose and predose Cycle 1 Day 2. Each cycle is 28 days. ]
    BH3 profiling on pretreatment and post-treatment bloods samples to assess whether add on treatment with PIT increases apoptotic priming.
