Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Objective response rate (Proportion of patients with reduction in tumor burden of a predefined amount)		At screening and every 8 weeks from time of first dosing until date of progression, start of other anticancer therapy or death whichever came first, assessed up to study completion (around 36 months).
Secondary	Safety and tolerability by assessing adverse events (AEs) based on CTCAE ver.4.03		All AEs occurring up to 28 days after the last administration of study drug until the start of other anti-cancer treatment, whichever comes first, will be record.
Secondary	Best overall response rate		At screening and every 8 weeks from time of first dosing until date of progression, start of other anticancer therapy or death whichever came first, assessed up to study completion (around 36 months).
Secondary	Disease control rate		At screening and every 8 weeks from time of first dosing until date of progression, start of other anticancer therapy or death whichever came first, assessed up to study completion (around 36 months).
Secondary	Progression-free survival		At screening and every 8 weeks from time of first dosing until date of progression, start of other anticancer therapy or death whichever came first, assessed up to study completion (around 36 months).
Secondary	Changes in molecular biomarkers		Screening and 15 days after first dosing
