研究认为,Durvalumab-铂-依托泊苷作为一线治疗手段可显著延长广泛性小细胞肺癌患者生存期

大多数广泛性小细胞肺癌(ES-SCLC)患者预后不佳,免疫治疗在ES- SCLC患者中显示出较好的临床效果。近日,在CASPIAN研究中,研究人员考察了Durvalumab联合或不联合Tremelimumab,与铂-依托泊苷联用治疗ES-SCLC的效果。


本次研究为III期临床研究,在23个国家开展,未经治疗的ES-SCLC患者参与,随机接受durvalumab-铂-依托泊苷、durvalumab- tremelimumab-铂-依托泊苷或铂-依托泊苷治疗。铂-依托泊苷疗法为:在每个周期的第1-3天接受依托泊苷80-100 mg/m2,在每个周期第1天开始5-6mg/ml卡铂或75-80 mg/m2顺铂。患者最多接受4轮的Durvalumab-铂-依托泊苷治疗,每3周一次,随后免疫组接受每4周1次1500mg durvalumab维持治疗,而单纯化疗患者接受最多6轮的铂-依托泊苷治疗以及预防性放疗。研究的主要终点为总生存期。


268名患者接受durvalumab-铂-依托泊苷治疗,269名接受铂-依托泊苷治疗。免疫组患者生存期显著改善,HR=0.73,平均生存期为13.0个月,而单纯化疗组为10.3个月。免疫组13个月患者生存率为34%,化疗组为25%。durvalumab组62%的患者出现3-4级不良事件,化疗组为62%,致死性不良事件发生率相近(5% vs 6%)。


研究认为,Durvalumab-铂-依托泊苷作为一线治疗手段可显著延长广泛性小细胞肺癌患者生存期。
