研究概览
简要总结
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.
详细描述
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.
