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

Analysis population: Pharmacokinetic (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, 'number analyzed' = participants evaluable for specified categories.
