智通财经APP获悉,强生(JNJ.US)宣布古塞奇尤单抗注射液(静脉输注)和古塞奇尤单抗注射液的新适应症上市申请已获得中国国家药监局(NMPA)批准,用于治疗中重度活动性克罗恩病成人患者。此前,古塞奇尤单抗已经在中国获批治疗银屑病。强生新闻稿表示,作为一款具有双重作用机制的白介素23抑制剂,本次是古塞奇尤单抗在全球范围内首次批准用于中重度活动性成人克罗恩病的治疗。
克罗恩病是一种慢性的全身性疾病,表现为胃肠道或消化道内炎症,发作时会引起持续性腹泻、腹痛和直肠出血。它是一种进行性疾病,会随着时间的推移而恶化。
古塞奇尤单抗此前已经在美国获批治疗中/重度斑块状银屑病、活动性银屑病关节炎、中度至重度活动性溃疡性结肠炎,此外其治疗中度至重度活动性克罗恩病的新适应症上市申请也已经于2024年6月获得FDA受理。
根据强生新闻稿,此次获批是基于GALAXI项目中两项关键3期研究(GALAXI 2和GALAXI 3)的临床数据。在试验中,古塞奇尤单抗的两个剂量组别都成功达到了共同主要终点,一方面在与安慰剂对比中,实现了具有统计学显著性和临床意义的临床和内镜结果,另一方面基于两项研究的汇总结果,在多重控制的内镜终点上展示出对比对照药的优效性。
