13. If female, the patient is pregnant or lactating.
14. Known allergy or hypersensitivity to any component of the study drug.
15. Gastrointestinal abnormalities including, but not limited to:
a. inability to take oral medication

E.5 End points

E.5.1

Primary end point(s)

Efficacy
PFS based on independent radiologic review using modified RECIST (mRECIST) (Appendix 17.1). mRECIST criteria includes:
• No lymph nodes chosen as target lesions; enlarged lymph nodes followed as non-target lesions;
• No bone lesions chosen as target lesions;
• PET not acceptable for radiological evaluation;
• A progressively growing new tumor nodule within a pre-existing tumor mass must meet the following criteria to be considered as unequivocal evidence of progression according to the modification of RECIST Version 1.1: (a) the lesion is at least 2 cm in size and definitively a new active GIST lesion (e.g. enhancing with contrast or other criteria to rule out artefact); or (b) the lesion has to be expanding on at least 2 sequential imaging
studies.

E.5.1.1

Timepoint(s) of evaluation of this end point

The primary endpoint of PFS (reported in weeks) is defined as the interval between the date of randomization and the earliest documented
evidence of disease progression based on the independent radiologic review, or death due to any cause. Patients who undergo surgical
resection of target or non-target lesions, who have received other anticancer treatments, or patients who do not have a documented date of progression or death due to any cause will be censored at the date of the last assessment.

E.5.2

Secondary end point(s)

Efficacy

• ORR (confirmed CR + confirmed PR) based on independent radiologic review using mRECIST criteria
• OS

Safety

Safety endpoints that will be evaluated include treatment-emergent adverse events (TEAEs), AESIs, SAEs, dose reduction or discontinuation of study drug due to toxicity; and changes from baseline in ECOG PS, vital signs, ECGs, LVEF, dermatologic examinations, and clinical laboratory parameters.
Pharmacokinetics
• Correlation of PK exposure with efficacy/safety
• Population-based PK parameters

E.5.2.1

Timepoint(s) of evaluation of this end point

Objective response rate: to be assigned a status of a CR or PR, changes in tumor measurements must be confirmed by repeat assessments that must be performed at least 4 weeks after the criteria for response are first met. Patients with unknown or missing response will be treated as non responders, that is, they will be included in the denominator when calculating the proportion. Time to confirmed response (CR or PR) (reported in weeks) is defined as the interval between the date of first dose of study medication and the earliest date of first documented confirmed CR or confirmed PR. Patients who do not have a confirmed PR or CR will be censored at the date of the last adequate assessment.
