Primary Outcome Measures
NameTimeMethod
Maximum Observed Plasma Concentration (Cmax)Predose, 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 4, 8, and 24 hours post-dose on Day 1 and 3

Maximum observed plasma concentration (Cmax) was calculated for Part A Pimasertib 60 mg Capsule and tablet.

Area Under the Plasma Concentration-time Curve From Zero to the Last Quantifiable Concentration (AUC 0-t)Predose, 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 4, 8, and 24 hours post-dose on Day 1 and 3

Area under the plasma concentration-time curve from time zero to the last sampling time (AUC0-t) at which the concentration was at or above the lower limit of quantification.

Secondary Outcome Measures
NameTimeMethod
Time to Reach Maximum Observed Plasma Concentration (Tmax)Predose, 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 4, 8, and 24 hours post-dose on Day 1 and 3
Apparent Terminal Half-life (t1/2)Predose, 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 4, 8, and 24 hours post-dose on Day 1 and 3
Area Under the Plasma Concentration-time Curve From Zero to Infinity (AUC0-inf)Predose, 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 4, 8, and 24 hours post-dose on Day 1 and 3
Apparent Volume of Distribution (Vz/f)Predose, 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 4, 8, and 24 hours post-dose on Day 1 and 3

Volume of distribution was defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed.

Number of Subjects With Treatment Emergent Adverse Events (TEAEs), Serious TEAEs, and TEAEs Leading to DiscontinuationFrom the first dose of study drug administration until 30 days after the last dose of study drug administration, assessed up to 14 Months

An AE was any untoward medical occurrence in a subject who received study drug without regard to possibility of causal relationship. 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. Treatment-emergent are events between first dose of study drug administration until 30 days after the last dose of study drug administration that were absent before treatment or that worsened relative to pre treatment state.

Terminal Rate Constant (λz)Predose, 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 4, 8, and 24 hours post-dose on Day 1 and 3
Part B: Number of Subjects Who Experienced Complete Response (CR)Screening to Day 1 of each cycle (21 day in each cycle) until disease progression, intolerable toxicity, withdrawal of consent or death; assessed up to 14 Months

CR as per Response Evaluation Criteria In Solid Tumors (RECIST) v1.1 defined as disappearance of all target lesions except lymph nodes (LN); LN must have a decrease in the short axis to less than (\<)10 millimeter (mm).

Part B: Number of Subjects Who Experienced Stable Disease (SD)Screening to Day 1 of each cycle (21 day in each cycle) until disease progression, intolerable toxicity, withdrawal of consent or death; assessed up to 14 Months

SD as per RECIST v1.1 defined as neither shrinkage to qualify for PR nor increase to qualify for progressive disease (PD) taking the smallest sum diameters on study as reference. PR = 30% decrease in sum of diameters of target lesions taking as reference the baseline sum diameters; PD = 20% increase in sum of diameters of target lesions; the appearance of \>=1 new lesions.

Part B: Number of Subjects Who Experienced Progressive Disease (PD)Screening to Day 1 of each cycle (21 day in each cycle) until disease progression, intolerable toxicity, withdrawal of consent or death; assessed up to 14 Months

PD as per RECIST v1.1 defined as 20% increase in sum of diameters of target lesions; the appearance of \>=1 new lesions.

Apparent Total Body Clearance (CL/f)Predose, 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 4, 8, and 24 hours post-dose on Day 1 and 3

Clearance of a drug was a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.

Part B: Number of Subjects Who Experienced Partial Response (PR)Screening to Day 1 of each cycle (21 day in each cycle) until disease progression, intolerable toxicity, withdrawal of consent or death; assessed up to 14 Months

PR as per RECIST v1.1 defined as 30% decrease in sum of diameters of target lesions taking as reference the baseline sum diameters.
