Core Viewpoint - Hansoh Pharmaceutical Group announced the approval of Amelot (Ametinib Mesylate Tablets) for a new indication, expanding its application to treat adult non-small cell lung cancer (NSCLC) patients with specific EGFR mutations [1][2] Group 1: Product Approval and Clinical Research - The new indication is for patients with stage II-III B NSCLC who have previously undergone surgical resection and may or may not receive adjuvant chemotherapy [1] - The approval is based on the ARTS (HS-10296-302) Phase III clinical study, which was presented at the 2025 American Association for Cancer Research (AACR) annual meeting [1] - The ARTS study demonstrated a significant improvement in disease-free survival (DFS) for patients receiving Amelot as adjuvant therapy, with a 2-year DFS rate of 90.2% [1] Group 2: Market Position and Expansion - Amelot, as China's first original third-generation EGFR-TKI, has been expanding its treatment areas since its launch five years ago [2] - The recent approval allows Amelot to cover early to mid-stage NSCLC (II-III stage), providing more treatment options for lung cancer patients in China [2]

Core Viewpoint - The 2025 CSCO Guidelines Conference has introduced the 2025 edition of the CSCO Guidelines for the Diagnosis and Treatment of Primary Non-Small Cell Lung Cancer (NSCLC), highlighting the inclusion of Hansoh Pharmaceutical's Amelot (Ametinib Mesylate Tablets) as the first Chinese original third-generation EGFR-TKI to receive a Class I recommendation for consolidation therapy in EGFR mutation-positive stage III unresectable NSCLC patients after chemoradiotherapy [1][2][3] Group 1 - The new recommendation is based on positive results from the POLESTAR study, a nationwide, multicenter, randomized, double-blind, controlled phase III clinical trial assessing the efficacy and safety of Amelot in consolidation therapy for stage III unresectable NSCLC patients with EGFR mutations after chemoradiotherapy [2] - The mid-term analysis of the POLESTAR study, presented at the 2024 World Lung Cancer Conference, showed a median progression-free survival (mPFS) of 30.4 months for the Amelot group, compared to 3.8 months for the placebo group, indicating an 8-fold improvement and an 85% reduction in the risk of disease progression or death [2] - The POLESTAR study exclusively included Chinese patients, demonstrating the significant efficacy of original EGFR-TKIs for domestic patients and providing high clinical relevance for China [2] Group 2 - NSCLC accounts for approximately 85% of all lung cancer cases in China, with nearly one-third being locally advanced (stage III) NSCLC, highlighting the urgent need for more precise and effective treatment options [2] - The rapid development of third-generation EGFR-TKIs represents a significant advancement in targeted therapy, offering more treatment choices to improve the diagnosis and treatment levels of stage III unresectable NSCLC and enhance patient prognosis [2] - The inclusion of Amelot as a Class I recommendation for consolidation therapy in this context confirms its application potential and is expected to guide the development of precision diagnosis and treatment for NSCLC in China, ultimately benefiting patients [3]
