Study Endpoints

Primary Endpoints

Part 1(dose-escalation part): Maximum Tolerated Dose (MTD)
Cycle 1 Day 1 to Cycle 1 Day 28

The maximum tolerated dose (MTD) of the CT053PTSA and gefitinib combination will be determined according to incidence of dose-limiting toxicity (DLT) assessed by NCI CTCAE v4.03

Part 2(expansion part): Overall Response Rate
up to approximately 36 months

Overall response rate (ORR), defined as a partial response (PR) or complete response (CR) occurring at any point post-treatment according to Response Evaluation Criteria in Solid Tumors as assessed by RECIST v1.1

Maximum Tolerated Dose (MTD)
Cycle 0 Day 1 to Cycle 1 Day 28

The maximum tolerated dose (MTD) of the CT053PTSA will be determined according to incidence of dose-limiting toxicity (DLT) assessed by NCI CTCAE v4.0

Secondary Endpoints

Number of patients with adverse events (AEs) as a measure of safety and tolerability
up to approximately 36 months
Disease Control Rate (DCR)
up to approximately 36 months
Progression-free Survival (PFS)
up to approximately 36 months

ArmTypeDescription
CT053PTSA +GefitinibEXPERIMENTALPatients will receive CT053PTSA and gefitinib over a 28-day cycle until progressive disease, intolerable toxicity or subject's withdrawal from treatment. CT053PTSA will be administered daily, at a dose of 30 mg/40mg/60mg orally . Gefitinib will be administered daily, at a dose of 250 mg orally .
CT053PTSA (dose escalation)EXPERIMENTALPatients were treated in 5 dose cohorts of 15 mg, 30 mg, 60 mg, 100 mg, and 150 mg QD capsules. Patients receive treatment with CT053PTSA once on Cycle 0 Day 1 following a 7-day treatment-free withdrawal period to observe the safety and pharmacokinetic of CT053PTSA. After that, Patients receive treatment with CT053PTSA per orally, beginning on Cycle 1 Day 1 for 28 day following a 7-day treatment-free withdrawal period to observe efficacy of CT053PTSA and determine to continue taking medicine or not. Each cycle had 28 days.
