今天万众瞩目的ECH-O301/Keynote-252试验因无效被提前终止。试验招募700多位无法手术的晚期恶性黑色素瘤病人，按PD-L1表达和BRAF突变分层，干预方法为Keytruda背景上加入IDO抑制剂Epacadostat，主要终点无进展生存期（PFS）和总生存期（OS）。今天公布的主要分析显示加入Epacadostat未能改善PFS（HR=1），改善OS的可能性也很小。因为IDO是PD

今天万众瞩目的ECH-O301/Keynote-252试验因无效被提前终止。试验招募700多位无法手术的晚期恶性黑色素瘤病人，按PD-L1表达和BRAF突变分层，干预方法为Keytruda背景上加入IDO抑制剂Epacadostat，主要终点无进展生存期（PFS）和总生存期（OS）。今天公布的主要分析显示加入Epacadostat未能改善PFS（HR=1），改善OS的可能性也很小。因为IDO是PD-1组合疗法的一个重要方向，这个失败不仅令Incyte下滑20%、默沙东下滑2%，也令多家开发IO组合的企业遭受不同程度打击。其中完全依靠IDO的Newlink下滑42%，开发所谓IDO2.0、选择性CD122激动剂的Nektar下滑近8%。全世界一片哗然，寄予厚望的免疫治疗联合使用，竟然失败了！



此前IDO+PD1的联用数据一路飘红：去年6月的ASCO2017大会上Incyte宣布epacadostat+ pembrolizumab治疗晚期NSCLC可使ORR和疾病控制率分别达到35%和63%；去年9月的ESMO2017大会上Incyte宣布I/II期ECHO-202（KEYNOTE-037）研究中epacadostat+ pembrolizumab可使晚期黑色素瘤患者的ORR达到56%；去年11月BMS公布的Opdivo联合自家IDO抑制剂BMS-986205的I/II期研究中，膀胱癌和宫颈癌队列患者也取得了积极结果。这一系列成功给人们IDO抑制剂联合PD-1/PD-L1以信心

尤其是I/II期ECHO-202研究（KEYNOTE-037研究）的临床数据。结果显示，所有患者（包括初治和经治患者）的ORR达到56%（35/63），完全缓解14%（9/63）；部分缓解41%（26/63），疾病稳定16%（10/63）。疾病控制率71%（45/63）。在所有35例产生应答的患者中，有30例在数据分析时仍维持缓解，中位缓解时间为45周（1+~121+周）。中位PFS为12.4个月；6个月时，疾病无进展的患者比例为65%；12个月时，疾病无进展的患者比例为52%；18个月时，疾病无进展的患者比例为49%。epacadostat各个剂量组（剂量递增25, 50, 100mg，bid）与Keytruda联用的效果一致。其中初治患者（一线治疗）黑色素瘤患者的mPFS高达22.8个月。ECHO-202研究可以说是大获成功！


ECHO-301（KEYNOTE-252）是一项随机、双盲、安慰剂对照研究，入组了706例不可手术切除或转移性黑色素瘤患者，按照1:1分组（根据PD-L1表达水平和BRAF突变状态和治疗情况对患者设置亚组），分别给予epacadostat + Keytruda或单独使用Keytruda。主要终点包括PFS和OS，次要终点包括ORR、安全性和耐受性。主要终点失败了。

IDO是过去5年制药工业最热门的未确证机理之一，理论是肿瘤利用这个酶的活性制造抑制免疫应答的犬尿氨酸。最早进入临床的是Newlink的NLG919，但这个药物并非IDO抑制剂、后来被包装成IDO通路抑制剂。Epac成为第一个真正的IDO抑制剂，前年在一个一/二期临床的恶黑亚组产生56%应答率，去年公布的长期跟踪结果显示PFS为22.8个月，这比单方使用Keytruda的历史数据更好（当然也远好于今天公布的ECHO301的11个月）。

williamhill asia 医学小编认为，I/II期结果与III期结果差异如此巨大，这也反映了临床试验的不易。如果比较ECHO-202和ECHO-301，在ECHO-202中，共纳入65例患者，其中初治为54例，所有人群的PFS（不是主要终点）这12.4个月(6.2, 23.8)，但初治患者PFS为22.8个月(6.2, 23.8)，初治患者在获得6个月的病情稳定后，绝大多数患者都能持续稳定到18个月以上，这是给ECHO-301作为恶黑的一线治疗提供信心。但是，二者不同的是，其一，ECHO-202样本量小，其中一线治疗仅54例，其二，地区不一样，ECHO-202在美国进行，而ECHO-301在全球进行，其三，ECHO-202评价PFS是次要终点，在患者获得ORR后，是否存在后续治疗？这些都有可能是偏倚。直接把I/II期结果迅速推广到III期，还是缺乏冷静，也可能是被胜利冲晕了头脑。可能是I/II期结果给予过高信心和期望，使得III期结果被认为是理所当然的阳性结果。就研究设计本身而言，可能过于冒进，毕竟，williamhill asia 对IDO的认知还十分肤浅，抑或是对于恶性黑色素瘤而言，Keytruda已足够的好，掩盖掉IDO类药物的作用。如果是前者，那么后面一系列的免疫治疗联用试验都可能面临危机，需要深入研究IDO的相关biomarker后，才有可能真正了解什么样的人群是IDO抑制剂的适合人群。如果是后者，在其它肿瘤中，成功概率是很大的，毕竟在其它肿瘤中，Keytruda表现虽然很优异，但并不是十分完美。而且除黑色素瘤，膀胱癌这类对免疫敏感性肿瘤外，其它肿瘤（如肺癌，乳腺癌，胃癌等），PD-1/PD-L1依然只是选择之一，还有很大的提升空间，免疫治疗联用策略，应该是令人期许的。

当然，ECHO-301失败，并不意味着结束，还有很多试验在路上，人类的探索也不会停止。
