Brief Summary

The purpose of this study was to assess the effect of multiple doses of carbamazepine on single- dose tepotinib pharmacokinetics in healthy participants. Study details include: Study Duration: up to about 10 weeks; Treatment Duration: single dose of tepotinib on Days 1 and 26, 25 days of treatment with carbamazepine (Days 8 to 32); Visit Frequency: residence in the Clinical Research Unit from Days -1 to 4 and Days 25 to 29, ambulatory daily visits from Days 5 to 24 and 30 to 33, and one ambulatory visit on Day 39.

Outcome Measures

Primary Outcomes (3)

• Area Under the Plasma Concentration-Time Curve From Time Zero Extrapolated to Infinity (AUC0-inf) of Tepotinib

  The AUC from time zero (= dosing time) extrapolated to infinity, based on the predicted value for the concentration at tlast, as estimated using the linear regression from lambda (λ)z determination.

  Predose 60 minutes before tepotinib dosing and 1, 1.5, 2, 3, 4, 6, 8, 12, 16, 24, 30, 38, 48, 60, 72, 96, 120, 144, and 168 hours post dose. Predose 60 minutes before carbamazepine dosing and 1, 1.5, 2, 3, 4, 6, and 8 hours post dose

• Area Under the Plasma Concentration-Time Curve (AUC) From Time Zero to Time of Last Measurable Concentration (AUC0-tlast) of Tepotinib

  The AUC from time zero (= dosing time) to the last sampling time (tlast) at which the concentration is at or above the lower limit of quantification. Calculated using the mixed log-linear trapezoidal rule (linear up, log down).

  Predose 60 minutes before tepotinib dosing and 1, 1.5, 2, 3, 4, 6, 8, 12, 16, 24, 30, 38, 48, 60, 72, 96, 120, 144, and 168 hours post dose. Predose 60 minutes before carbamazepine dosing and 1, 1.5, 2, 3, 4, 6, and 8 hours post dose

• Maximum Observed Plasma Concentration (Cmax) of Tepotinib

  Cmax was obtained directly from the concentration versus time curve.

  Predose 60 minutes before tepotinib dosing and 1, 1.5, 2, 3, 4, 6, 8, 12, 16, 24, 30, 38, 48, 60, 72, 96, 120, 144, and 168 hours post dose. Predose 60 minutes before carbamazepine dosing and 1, 1.5, 2, 3, 4, 6, and 8 hours post dose

Secondary Outcomes (8)

  Baseline (Day 1) up to 10 Weeks

• Number of Participants With Clinically Meaningful Change From Baseline in Laboratory Values

  Baseline (Day 1) up to 10 Weeks

  Baseline (Day 1) up to 10 Weeks

• Number of Participants With Clinically Meaningful Change From Baseline in Vital Signs

  Baseline (Day 1) up to 10 Weeks

• Total Body Clearance of Drug From Plasma (CL/f) for Tepotinib

  Predose 60 minutes before tepotinib dosing and 1, 1.5, 2, 3, 4, 6, 8, 12, 16, 24, 30, 38, 48, 60, 72, 96, 120, 144, and 168 hours post dose. Predose 60 minutes before carbamazepine dosing and 1, 1.5, 2, 3, 4, 6, and 8 hours post dose

You may qualify if:

• Overtly healthy participants as determined by medical evaluation, including no clinically significant abnormality identified by medical history, cardiac monitoring, physical examination or laboratory evaluation and no active clinically significant disorder, condition, infection or disease that would pose a risk to participant safety or interfere with the study evaluation, procedures, or completion at Screening and Day -1
