ClinConnect Summary

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 N...
