Exclusion criteria
Participants received Tepotinib hydrochloride hydrate film-coated tablet once daily with food on Day 1 and Day 26 in the morning.
Carbamazepine 100 mg twice daily at Day 8 and 9, 200 mg twice daily at Day 10 and 11, 300 mg twice daily from Day 12 to 32.
Time frame: 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
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.
Time frame: 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
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).
Time frame: 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
Cmax was obtained directly from the concentration versus time curve.
Time frame: Baseline (Day 1) up to 10 Weeks
An adverse event (AE) was defined as any untoward medical occurrence in a participant. An AE was any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with use of a study intervention. A serious adverse event (SAE) was any untoward medical occurrence that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. TEAE's were those events with onset dates on or after the first administration of study intervention. Severity of abnormalities were evaluated using the Common Terminology Criteria for Adverse Events (CTCAE) version [24.1].
grade 1 : mild grade 2 : moderate grade 3 : severe or medically significant but not immediately life-threatening grade 4 : life threatening or disabling grade 5 : death related to AE
Time frame: Baseline (Day 1) up to 10 Weeks
Number of participants with clinically significant change from baseline in laboratory parameters were reported. Clinical Significance was decided by the investigator. Laboratory investigation included hematology, biochemistry, urinalysis, and coagulation.
Time frame: Baseline (Day 1) up to 10 Weeks
Number of participants with clinically significant change from baseline in ECG parameters were reported. Clinical Significance was decided by the investigator. The 12-lead ECGs were recorded after the participants have rested for at least 5 minutes in supine position. The parameters included heart rate (HR), Respiratory Rate, Pulse Rate, QRS, QT and QTcB calculated by the Bazett formula.
Time frame: Baseline (Day 1) up to 10 Weeks
Number of participants with clinically significant change from baseline in vital signs. Clinical Significance was decided by the investigator. Vital signs included oral body temperature, systolic blood pressure, diastolic blood pressure, and pulse rate.
Time frame: 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
CL/f following oral administration was calculated as Dose/AUC0-inf, where AUC0-inf calculated as AUC0-t + AUCextra. AUCextra represents the extrapolated part of AUC0-inf calculated by Clastcalc/λz, where Clastcalc was the calculated plasma concentration at the last sampling time point at which the measured plasma concentration was at or above the LLOQ and λz was the apparent terminal rate constant determined from the terminal slope of the log-transformed plasma concentration curve.
Time frame: 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
Vz/F was defined as the apparent volume of distribution during the terminal phase following extravascular administration.
Time frame: 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
The time to reach the maximum observed plasma concentration (Tmax) was obtained directly from the concentration versus time curve.
Time frame: 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
t1/2 was defined as the time taken for the plasma concentration or the amount of drug in the body to be reduced by half.
