ECOG PS score is widely used by doctors and researchers to assess how a subjects' disease is progressing, and is used to assess how the disease affects the daily living abilities of the subject, and determine appropriate treatment and prognosis. The score ranges from Grade 0 to Grade 4, where Grade 0 = Fully active, able to carry on all pre-disease performance without restriction, Grade 1 = Restricted in physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature (like light house work, office work), Grade 2 = Ambulatory and capable of all self-care but unable to carry out any work activities, Grade 3 = Capable of only limited self-care, confined to bed or chair more than 50% of waking hours and Grade 4 = Completely disabled. Cannot carry on any self-care. Totally confined to bed or chair.

Terminal half-life is the time measured for the plasma concentration to decrease by one half. Terminal half-life is calculated by dividing the natural logarithm to the base 2 (Ln2) divided by elimination rate constant (λz), where 'λz' is calculated by a linear regression of the log-linear concentration-time curve.

AUC(inf) was calculated by combining AUC0-t and AUCextra. AUCextra represented an extrapolated value obtained by Clast/λz, where Clast was the calculated plasma concentration at the last sampling time point at which the measured plasma concentration was at or above the LLQ and λz is the terminal elimination rate constant.

Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. CL/F = Dose/AUC(inf), where AUC(inf) =AUC0-t + AUCextra. AUCextra represented an extrapolated value obtained by Clast/λz, where Clast was the calculated plasma concentration at the last sampling time point at which the measured plasma concentration was at or above the LLQ and λz is the terminal elimination rate constant.

Volume of distribution is 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 and is calculated by Dose/(AUC(inf)*λz).

Area under the plasma concentration versus time curve from time zero to the last sampling time t at which the concentration is at or above the lower limit of quantification (LLQ) AUC0-t was calculated according to the mixed log-linear trapezoidal rule

Number of subjects with BOR in each category (complete response [CR], partial response [PR], stable disease [SD], progressive disease [PD]) according to Response Evaluation Criteria in Solid Tumors (RECIST Version 1.1) was reported. CR: defined as disappearance of all target and all non-target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. PR: defined as at least a 30% decrease in sum of longest diameter of target lesions, taking as reference the baseline sum of longest diameter. PD: defined as at least a 20% increase in sum of longest diameter of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study) or unequivocal progression of existing non-target lesions. SD: defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum of longest diameter while on study.

Clinical Benefit was defined as CR or PR at any time point or SD at week 12 or later, based on tumor assessment as determined by Response Evaluation Criteria in Solid Tumors (RECIST 1.1). CR: defined as disappearance of all target and all non-target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. PR: defined as at least a 30% decrease in sum of longest diameter of target lesions, taking as reference the baseline sum of longest diameter.

PFS was defined as the time in months from the first administration of trial treatment until first observation of progressive disease (PD), or death due to any cause when death occurs within 12 weeks of the last tumor assessment or first administration of trial treatment (whichever is later). Any subject with neither assessment of tumor progression, nor death within 12 weeks after last tumor assessment date was censored on the date of last tumor assessment. PFS was planned to be presented for "MSC2156119J Combined" reporting arm.

Subjects were administered with MSC2156119J 500 mg orally once daily for repeated 21-day cycles until disease progression or unacceptable toxicity.

An adverse event (AE) was defined as any untoward medical occurrence in a subject which does not necessarily have a causal relationship with the study drug. An AE was defined as any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug or worsening of pre-existing medical condition, whether or not related to study drug. A serious adverse event (SAE) was an AE 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. Treatment-emergent are events between first dose of study drug and up to 30 days after last dose that were absent before treatment or that worsened relative to pre-treatment state. TEAEs include both Serious TEAEs and non-serious TEAEs.

Safety analysis set included all subjects who had received at least 1 dose of the IMP.

Terminal half-life is calculated by dividing the natural logarithm to the base 2 (Ln2) divided by elimination rate constant (λz), where 'λz' is calculated by a linear regression of the log-linear concentration-time curve.

It was not possible to calculate data for this outcome measure because dosing interval was too small compared to the long half-life to characterize the terminal phase rate constant, which is needed for the calculation of t1/2.

AUCextra represented an extrapolated value obtained by Clast/λz, where Clast was the calculated plasma concentration at the last sampling time point at which the measured plasma concentration was at or above the LLQ and λz is the terminal elimination rate constant.
