MeasureTime frameDescription
Number of Participants Who Experienced a Treatment-emergent AE (TEAE)Day 1 to Day 9An AE is any untoward medical occurrence in a participant irrespective of a causal relationship with the study treatment. Any abnormal clinical laboratory test results (hematology, clinical chemistry, or urinalysis) or other safety assessments (e.g., 12-lead electrocardiogram or vital signs measurements), including those that worsen from baseline, that are considered clinically significant in the medical and scientific judgment of the Investigator (i.e., not related to progression of underlying disease) were considered AEs.

Recruitment details

Overall, 145 participants were enrolled in the study in the United States between 16 August 2021 and 18 February 2022.

Pre-assignment details

After randomization, participants received Treatment A (test 1) and Treatment B (reference) according to the treatment sequence assigned. A group of participants from both arm proceeded to receive Treatment C (test 2) with a high-fat meal. Dose administration of sotorasib occurred on Day 1 (Period 1) and Day 4 (Period 2) under fasted conditions and on Day 7 (Period 3) under fed condition.

Area Under the Plasma Concentration-Time Curve From Time Zero to Infinity (AUCinf) of Sotorasib for Treatments A and B

Blood samples were collected by venipuncture or cannulation for measurement of plasma concentrations of sotorasib. Plasma PK parameters of sotorasib were summarized per treatment received, regardless of treatment sequence, as pre-specified.

Time frame: Predose (Hour 0), 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 12, 24, 36, and 48 hours postdose following administration of sotorasib on Day 1 (Period 1) and Day 4 (Period 2)

Population: The PK population included all participants who received at least 1 dose of sotorasib in Periods 1 and 2, and had evaluable PK data. A participant may have been excluded from the PK summary statistics and statistical analysis if the participant had an AE of vomiting that occurred at or before 2 times median tmax or diarrhea within 24 hours of dosing.
