An SAE was an AE resulting in any of the 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.
Number of Participants With Drug Related Treatment Emergent Adverse Events (TEAEs): Part 1
TEAEs are events that occurred on or after initial treatment that were absent before treatment or worsened during the treatment period relative to the pretreatment state. AEs that occurred within 30 days of the last administration of study treatment can be attributed to the treatment period.
Number of Participants With Drug Related Grade 3 and Higher Treatment Emergent Adverse Events (TEAEs): Part 1
TEAEs are events that occurred on or after initial treatment that were absent before treatment or worsened during the treatment period relative to the pretreatment state. AEs that occurred within 30 days of the last administration of study treatment can be attributed to the treatment period.

Title
Number of Participants for Change From Baseline in the Phosphorylation of Mammalian Target of Rapamycin (mTOR) Pathway Proteins: Part 1 and Part 2
Description
Optional bone marrow sampling for pharmacodynamic analysis of effects of study treatment. Data may not be collected for a majority of patients and was not to be summarized if collection was sparse.
Time Frame
Part 1:Baseline,1,2,6,24,168 hrs post-dose of Cycle 1;additional 0 (Pre-dose),24,72,96 hrs, Day 16 to 21 of cycle 2, EOT(within 30 days of last dose); Part 2:Baseline,Day16 to 21 in Cycle 2, at time of disease progression, EOT(within 30 days of last dose)
