Neoadjuvant Therapy With Ensartinib Combined With Chemotherapy for ALK-positive Non - Small Cell Lung Cancer (NSCLC)

The goal of this clinical trial is to learn if Ensartinib combined with chemotherapy works as a neoadjuvant treatment for patients with stage II-IIIB (N2) ALK-positive non-small cell lung cancer (NSCLC). It will also learn about the safety of this combination therapy. The main questions it aims to answer are: * Does Ensartinib combined with chemotherapy lead to a pathological complete response (pCR) in surgically removed tumor tissue after neoadjuvant treatment? * What medical problems do participants have when taking Ensartinib combined with chemotherapy? This is a single-arm study, meaning all participants will receive the investigational treatment. There is no placebo or active comparator group. The study will be conducted in two stages; the second stage will proceed only if no special, unexpected, or serious adverse events related to Ensartinib occur during the first stage involving 5 participants. Participants will: * Receive neoadjuvant treatment with Ensartinib (taken orally once daily) plus Pemetrexed and Carboplatin (administered intravenously every 3 weeks) for 9 weeks (3 cycles). * Undergo surgical resection within 4 weeks after completing neoadjuvant therapy. * Attend regular clinic visits for check-ups, blood tests, and imaging scans (CT, MRI) according to a detailed schedule during the neoadjuvant, surgical, and long-term follow-up periods (up to 10 years). * Be monitored for adverse events and survival outcomes.
