Brief summary
This study is an open-label, randomized, multicenter phase II/III clinical trial designed to evaluate the efficacy, safety, and tolerability of Andamertinib with or without platinum-based chemothsrapy versus platinum-based chemotherapy in previously untreated participants with locally advanced or metastatic non-squamous NSCLC harboring EGFR atypical mutations. The study comprises two stages: phase II (dose-exploration stage) and phase III (pivotal study stage)
Detailed description
This a three-stage study consist a Screening Phase (Day -28 to -1), a Treatment Phase (until treatment discontinuation), and a Follow-up Phase (including end of treatment visit (EOT),end of study visit(EOS), safety follow-up and survival follow-up).

Secondary
| Measure | Time frame | Description |
|---|---|---|
| Objective Response Rate (ORR) | Up to 3 years | To evaluate the Overall Response Rate (ORR) which is defined by investigator as the proportion of subjects with confirmed best overall response of complete response or partial response per RECIST v1.1 |
| Duration of Response(DOR) | up to 3 years | DOR is defined as the time from the date of first documented response (CR or PR) until the date of documented progression or death, whichever comes frst |
| Disease Control Rate(DCR) | up to 3 years | The percentage of tumor patients achieving complete remission (CR), partial remission (PR), or stable disease (SD) following treatment, relative to the total number of evaluable subjects |
| Progression-Free Survival(PFS) | up to 3 years | PFS is defined as the time from the date the first dose until the date of objective disease progression or death by cause whichever comes first, based on investigator review according to RECIST v1.1 |
| 6-month Progression-Free Survival Rate | up to 3 years | The proportion of subjects who did not experience disease progression or death within 6 months after receiving treatment. |
| 6-month Overall Survival Rate | up to 3 years | The proportion of subjects who did not experience death within 6 months after receiving treatment. |
| Assess the PK characteristics of Andamertinib | On cycle1of day 1and cycle3of day1, samples were collected within 2 hours prior to dosing and 4 hours post-dosing,On Day 1of Cycle 2, Cycle 5, Cycle 7, and all subsequent odd-numbered cycles collected within 2hours prior to dosing(each cycle is 21days) | Plasma concentration of Andamertinib |
