Cycle 1 and Cycle 3 (each cycle length = 21 days)

Analysis population: PK analysis set included all participants who received at least 1 dose of study drug and from whom results of concentration had been obtained at least 1 sampling point. PK data were collected and analyses were conducted in participants per treatment schedule and dose in both phases (dose escalation and expansion) combined. Here, 'Overall number of participants analyzed' = participants evaluable for this outcome measure. 'Number analyzed' = participants evaluable at specified timepoint.
