金吾财讯 | 华泰证券研报指,11月4日,康诺亚-B(02162)披露了TSLP/IL-13双抗CM512治疗AD的I期临床结果:首月3次给药后,300mg剂量组12周的EAS-75/90分别为58.3/41.7%,优于安慰剂组的21.4/0%,同时展现出70天的长半衰期,验证更长给药周期潜力。该机构认为CM512已充分展现成药性,同时与其他单靶点AD药物相比显现了BIC潜力,全球竞争力开始进入验证期。除本I期临床外,CM512在国内外的多适应症探索已然展开:1)海外I期临床近期或完成健康人入组,哮喘患者入组已然展开;2)国内启动了哮喘、COPD、CRSwNP、慢性自发性荨麻疹4个适应症的II期临床,加速对呼吸/鼻科的探索,由于赛诺菲的lunsekimig已经显示TSLP/IL-13双靶药物针对单靶点药物在哮喘治疗上的明显优势,该机构认为CM512在该领域的竞争力或更进一步。考虑到CM512具有长效(半衰期70天 vs lunsekimig 10天)、海外数据潜力、初步疗效验证等优势,该机构认为其再合作潜力可期。考虑达必妥的短期医保销售优势,该机构调整了司普奇拜单抗的销售放量节奏的预期,下调公司25-27年净利润预测为-6.79/-6.70/-2.82亿元(前值:-7.42/-6.04/1.00亿元),同时基于CM512优异早期数据,该机构上调了其开发成功率,并上调了2027年以后的远期收入假设,上调基于DCF的目标价为91.08港币(WACC:9.0%,永续增长率2.5%;前值90.89港币基于同样的WACC和永续增长率)。维持“买入”评级。
