疫苗界传来好信息,走投没路的晚期癌症又现新期盼
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">在2020年美国癌症<span style="color: black;">科研</span>协会(AACR)年会上,一项新型的个体化癌症疫苗<span style="color: black;">颁布</span>了其一期的临床数据,接受疫苗治疗的<span style="color: black;">病人</span>大多都是极晚期伴有转移病灶的<span style="color: black;">病人</span>,并且<span style="color: black;">已然</span>接受过免疫治疗<span style="color: black;">或</span>是PD-L1低表达,结果<span style="color: black;">表示</span>,新型疫苗<span style="color: black;">能够</span>激活<span style="color: black;">自己</span>的免疫系统,近一半的<span style="color: black;">病人</span>病情稳定,并且疫苗安全可控。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">这一<span style="color: black;">科研</span>结果<span style="color: black;">没</span>疑让人感到振奋,<span style="color: black;">由于</span><span style="color: black;">针对</span>这些走投<span style="color: black;">没</span>路的<span style="color: black;">病人</span>,这款新型疫苗是其<span style="color: black;">存活</span>的新<span style="color: black;">期盼</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">21世纪是免疫治疗爆发的时代,免疫<span style="color: black;">检测</span>点<span style="color: black;">控制</span>剂、肿瘤过继性细胞疗法和肿瘤疫苗<span style="color: black;">作为</span>三足鼎立的免疫治疗<span style="color: black;">办法</span>。其中肿瘤疫苗<span style="color: black;">做为</span><span style="color: black;">要紧</span>的免疫疗法之一,<span style="color: black;">始终</span>是肿瘤学家的<span style="color: black;">科研</span>热点。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">从疫苗<span style="color: black;">功效</span><span style="color: black;">归类</span>,肿瘤疫苗分为预防型和治疗型两类,<span style="color: black;">大众</span>熟知的宫颈癌HPV疫苗就属于预防型疫苗,其<span style="color: black;">功效</span>是预防HPV病毒的感染,从而预防肿瘤的<span style="color: black;">出现</span>,对<span style="color: black;">已然</span><span style="color: black;">出现</span>的肿瘤<span style="color: black;">无</span>治疗<span style="color: black;">功效</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">而<span style="color: black;">包含</span>古巴肺癌疫苗在内的其他肿瘤疫苗都属于治疗型疫苗,是<span style="color: black;">拥有</span>治疗<span style="color: black;">功效</span>的肿瘤疫苗,<span style="color: black;">通常</span>治疗型疫苗都<span style="color: black;">拥有</span>预防复发的<span style="color: black;">功效</span>。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">本<span style="color: black;">科研</span>所<span style="color: black;">触及</span>的疫苗名为RO7198457,由伦敦癌症<span style="color: black;">科研</span>所的肿瘤学家<span style="color: black;">开发</span>,是一种基于信使RNA(mRNA)的治疗型癌症疫苗。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">科研</span>者<span style="color: black;">经过</span>对<span style="color: black;">病人</span>的肿瘤组织和血液样品进行测序,鉴定肿瘤特异性新抗原后,找到对应的mRNA,从而制成相应的疫苗,<span style="color: black;">因此呢</span>这是一款<span style="color: black;">按照</span><span style="color: black;">病人</span><span style="color: black;">自己</span>肿瘤量身定制的肿瘤疫苗,<span style="color: black;">拥有</span>超高的个性化和特异性。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">该<span style="color: black;">科研</span>共纳入144例晚期实体瘤<span style="color: black;">病人</span>,<span style="color: black;">包含</span>非小细胞肺癌(NSCLC),黑素瘤,三阴性乳腺癌和尿路上皮癌。近40%的<span style="color: black;">病人</span>接受过接受免疫治疗,大<span style="color: black;">都数</span><span style="color: black;">病人</span>PD-L1阴性或低表达。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">在诱导期的12周<span style="color: black;">时期</span>,每周一次或每两周一次静脉内输入9剂RO7198457,在维持期中,每24周一次。在<span style="color: black;">每一个</span>周期的第1天加用1200 mg阿特珠单抗。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">在可<span style="color: black;">评定</span>的108例<span style="color: black;">病人</span>中,有9例有反应,总体反应率为8%。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">1例结直肠癌<span style="color: black;">病人</span>完全缓解,其中53例<span style="color: black;">病人</span>(占可<span style="color: black;">评定</span><span style="color: black;">病人</span>的49%)病情稳定。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">该疫苗在77%的<span style="color: black;">病人</span>中诱导了新抗原特异性T细胞反应。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">大<span style="color: black;">都数</span>不良反应为1级或2级。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">值得一提的是,在一例三阴乳腺癌中<span style="color: black;">显现</span>部分缓解,这位<span style="color: black;">病人</span>之前<span style="color: black;">已然</span>接受了PD-1治疗,并且<span style="color: black;">显现</span>了淋巴结转移。再接受了疫苗的治疗后,并所有的肿瘤<span style="color: black;">所有</span>缩小或消失。<span style="color: black;">科研</span>人员分析后<span style="color: black;">发掘</span>,这位<span style="color: black;">病人</span>的<span style="color: black;">身体</span>在接受疫苗后<span style="color: black;">显现</span>了新抗原特异性T细胞的数量达到2.2%,<span style="color: black;">日前</span>这位<span style="color: black;">病人</span>在一年半后仍<span style="color: black;">处在</span>良好的<span style="color: black;">科研</span>状态。</p>
