The purpose of this study was to assess the effect of multiple doses of itraconazole on single dose tepotinib pharmacokinetics in healthy participants. Study details include: Study Duration: up to 48 days Treatment Duration: single dose of tepotinib on Days 1 and 12, 11 days of treatment with itraconazole (Days 8 to 18) Visit Frequency: residence in the Clinical Research Unit from Days -1 to 4 and Days 11 to 15, ambulatory daily visits from Days 5 to 10 and 16 to 20

Participants received Tepotinib (Hydrochloride hydrate) Film-coated tablet with food on Day 1 and 12 in the morning.
Participants received Itraconazole Hard-gelatin capsule with food once daily at the same time in the morning from Day 8 to Day 18; on Day 12 itraconazole is administered concomitantly with tepotinib.

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.
Time frame: Predose up to 168 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 time of the last quantifiable concentration (tlast). Calculated using the mixed log-linear trapezoidal rule (linear up, log down).
Time frame: Predose up to 168 hours post dose
Maximum Observed Plasma Concentration (Cmax) of Tepotinib and Metabolite
Cmax was obtained directly from the concentration versus time curve.
Time frame: Predose up to 168 hours post dose
Number of Participants With Treatment-emergent Adverse Events (TEAEs), Serious TEAEs, TEAES With Severity of Grade Greater or Equal to 3
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 follow up (assessed up to Day 20)
Number of Participants With Clinically Meaningful Change From Baseline in Laboratory Values
Laboratory investigation included hematology, biochemistry and urinalysis. Clinically meaningful was decided by the investigator. Number of participants with clinically meaningful change from baseline in laboratory values were reported.
Time frame: Baseline (Day 1) up to follow up (assessed up to Day 20)
Number of Participants With Clinically Meaningful Change From Baseline in Electrocardiogram (ECG)
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. Clinical Significance was decided by the investigator. Number of participants with clinically meaningful change from baseline in ECG parameters were reported.
Time frame: Baseline (Day 1) up to follow up (assessed up to Day 20)
Number of Participants With Clinically Meaningful Change From Baseline in Vital Signs
Vital signs included oral body temperature, systolic blood pressure, diastolic blood pressure, and pulse rate. Clinical Significance was decided by the investigator. Number of participants with clinically significant change from baseline in vital signs.
Time frame: Baseline (Day 1) up to follow up (assessed up to Day 20)
Total Body Clearance of Drug From Plasma (CL/f) for Tepotinib
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 up to 168 hours post dose
Apparent Volume of Distribution (Vz/f) for Tepotinib
Vz/F was defined as the apparent volume of distribution during the terminal phase following extravascular administration.
Time frame: Predose up to 168 hours post dose
Time to Reach the Maximum Plasma Concentration (Tmax) of Tepotinib
The time to reach the maximum observed plasma concentration (Tmax) was obtained directly from the concentration versus time curve.
Time frame: Predose up to 168 hours post dose
Apparent Terminal Half-Life (t1/2) of Tepotinib in Plasma
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.
Time frame: Predose up to 168 hours post dose
