A Phase Ib, Multi-center, Open Label Study of Ningetinib (CT053PTSA) in Combination With Gefitinib in Stage IIIB or IV NSCLC Patients With EGFR Mutation and T790M Negative Who Have Progressed After EGFR TKI Therapy

This is a phase Ib, multi-center, open label study evaluating the safety and efficacy of CT053PTSA in combination with gefitinib in patients with EGFR mutation, T790M negative NSCLC who have progressed after EGFR TKI treatment.

Study Overview

• Status: Active, not recruiting
• Conditions: Non-small Cell Lung Cancer
• Intervention / Treatment: Drug: Gefitinib; Drug: CT053PTSA

Detailed Description

This study is being carried out in two parts, part 1 and part 2.

Part 1: This is the dose-escalation part. The primary purpose of the part 1 portion is to determine the dose limiting toxicity (DLT) and maximum tolerated dose (MTD), and recommend the appropriate doses of CT053PTSA in combination with gefitinib for further studies.

Part 2: This is the expansion part. The part 2 portion of this study will continue to evaluate the safety and efficacy of the combination of CT053PTSA and gefitinib , at the appropriate doses recommended in Part 1, in patients with EGFR mutation, T790M negative NSCLC.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Part 1（dose-escalation part）: Maximum Tolerated Dose (MTD)	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	Cycle 1 Day 1 to Cycle 1 Day 28
