金吾财讯 | 招银国际研报指,康方生物(09926)依沃西单抗海外合作伙伴Summit公布了HARMONi全球临床试验的最新数据,该研究评估AK112联合化疗对比单独化疗在二线三代EGFR-TKI耐药NSCLC患者中的疗效。西方患者的无进展生存期(PFS)风险比(HR)逊于中国患者,长期随访下的总生存期(OS)HR也同样落后于中国人群。鉴于此,投资者担心AK112在中国所获得的数据能否成功外推至全球市场。然而,该机构更关注OS结果,并认为中西人群OS差异在一定程度上可能源于西方患者(尤其是欧洲患者)随访时间较短。值得注意的是,在超出最终OS分析的更长期随访中观察到了积极的OS趋势。北美患者群体也展现出较强的OS表现。目前二线EGFR突变NSCLC治疗仅占AK112长期销售潜力的不到5%,该机构认为AK112在NSCLC领域的主要价值在一线适应症。该机构预计HARMONi-6中国一线研究将在2025年ESMO大会上公布结果,同时HARMONi-2研究的进一步OS数据也将在未来六个月内更新(Summit指引)。该机构认为HARMONi试验展现了积极的OS趋势,进一步增强了该机构对其一线适应症潜力的信心。维持DCF估值得出的目标价不变,为182.12港元(WACC: 8.37%,永续增长率:4.5%)。维持“买入”评级。
