A Randomized Phase II Multicenter, Open-Label Study Evaluating the Efficacy and Safety of IMAB362 in Combination With the EOX (Epirubicin, Oxaliplatin, Capecitabine) Regimen as First-Line Treatment of Patients With CLDN18.2-Positive Advanced Adenocarcinomas of the Stomach, the Esophagus or the Gastroesophageal Junction
The purpose of the trial is to assess the therapeutic effects and the safety profile of IMAB362 combined with EOX (epirubicin, oxaliplatin, capecitabine) as first-line treatment for patients with advanced adenocarcinoma of the stomach, the esophagus or the gastroesophageal junction compared to EOX alone.
Furthermore, sufficient binding of IMAB362 to the target cells is necessary for antitumoral activity. Thus, two dose levels ensuring a serum level above the in vitro predicted clinical efficacy threshold will be investigated.

1月9日,博安生物的注射用BA1301获得CDE批准临床,适用于治疗Claudin18.2表达的晚期实体瘤,包括晚期胃癌、胃食管结合部腺癌和胰腺癌等患者的治疗。
注射用BA1301是博安生物首个的ADC候选产品,靶向CLDN18.2,采用合作伙伴联宁(苏州)生物制药的C-Lock定点偶联技术,将小分子细胞毒素与靶向Claudin18.2的单抗偶联,通过抗体的靶向性引导小分子毒素到达肿瘤部位,发挥杀伤肿瘤效果的同时,降低小分子毒素的毒副作用,提高治疗窗口。
临床前药效研究结果表明:注射用BA1301具有优异的内化活性和旁杀效果;在不同Claudin18.2表达水平的肿瘤细胞模型上均展示优异的体内外肿瘤生长抑制效果。
已完成的临床前药代动力学、毒理学研究结果显示:注射用BA1301的小分子毒素基本未见脱落,在动物体内具有良好的安全性和耐受性。
Claudin18.2靶向药物获批尚未上市,目前进度最快的是安斯泰来的zolbetuximab(IMAB362)。另外,目前ADC药物共8款。
