<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">一项I / IIa随机<span style="color: black;">科研</span>,<span style="color: black;">评定</span>了SNK01联合PD-1(派姆单抗)在IV期非小细胞肺癌<span style="color: black;">病人</span>中的安全性和有效性,摘要编号3037。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">这项<span style="color: black;">科研</span>纳入了20例IV期非小细胞肺癌(PD-L1 +,EGFR-,ALK-),这些<span style="color: black;">病人</span>接受了一线铂类治疗并失败了,随机分配至两组:</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">A组接受PD-1(派姆单抗)+SNK01治疗(每六周2 x 10⁹或4 x 10⁹个细胞)</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">B组<span style="color: black;">病人</span>仅接受派姆单抗,在21天周期的第1天注射。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">结果<span style="color: black;">表示</span>:</p>联合治疗组的总体缓解率(ORR)为44%,与Keytruda单独治疗的0%相比,<span style="color: black;">显著</span>更高;并且接受最高剂量的NK细胞治疗的<span style="color: black;">病人</span>的ORR<span style="color: black;">能够</span>达到50%;中位<span style="color: black;">没</span><span style="color: black;">发展</span><span style="color: black;">存活</span>期(PFS):联合治疗组为8个月,单药治疗组仅为1.6个月;中位总<span style="color: black;">存活</span>期(mOS):联合治疗组尚未达到,单药组为6个月。与单独<span style="color: black;">运用</span>Keytruda的25%3-5级毒性相比,用联合治疗的<span style="color: black;">病人</span><span style="color: black;">无</span>与治疗<span style="color: black;">关联</span>的毒性,并且总体生活质量更好。<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">总结:虽然这只是一项小型<span style="color: black;">科研</span>,但这些初步结果<span style="color: black;">已然</span><span style="color: black;">显示</span>,与单独<span style="color: black;">运用</span>基于Pembrolizumab的铂类治疗失败的IV期NSCLC患者相比,Pembrolizumab联合NK细胞治疗非常安全,<span style="color: black;">乃至</span><span style="color: black;">能够</span>降低PD-1<span style="color: black;">关联</span>的毒性,<span style="color: black;">同期</span><span style="color: black;">增多</span>总体肿瘤反应。<span style="color: black;">咱们</span>期待更大规模的<span style="color: black;">实验</span>数据来证实这些免疫疗法全新的尝试<span style="color: black;">可否</span>能给病友们带来更大<span style="color: black;">存活</span>获益!</p>
