安进与合作伙伴诺华近日在美国洛杉矶举行的第70届美国神经病学学会(AAN)年度会议上公布了偏头痛新药Aimovig(erenumab)IIIb期临床研究LIBERTY的完整数据,该研究在既往已接受2-4种预防性药物、但因缺乏疗效或无法耐受副作用而治疗失败的发作性偏头痛(EM)患者中开展,这是一个非常独特的难治性患者群体,常常被排除在偏头痛预防性研究之外。数据证实,Aimovig在这类患者中可作为一种有效的预防性治疗选择。
Aimovig是一种单克隆抗体药物,通过靶向阻断降钙素基因相关肽(CGRP)受体来预防偏头痛,该受体被认为在偏头痛的发生中发挥了关键作用。值得一提的是,LIBERTY是首个专门在这一类难治性患者中所开展的调查靶向CGRP通路药物分子的临床研究。
LIBERTY(NCT03096834)是一项多中心、随机、双盲、安慰剂对照、12周IIIb期研究,在246例EM(定义为每月偏头痛基线天数为4-14天)患者中开展,这些患者在入组研究前已接受过2-4种预防性药物但治疗失败。研究中,患者随机分配至每月一次皮下注射Aimovig(140mg)或安慰剂,进行为期12周的双盲治疗。研究的主要终点是在双盲治疗期的最后4周(第9-12周)每月偏头痛天数从基线下降至少50%的患者比例。该研究还包括一个正在进行的为期52周的开放标签扩展期。
数据显示,Aimovig治疗组每月偏头痛天数从基线下降至少50%的患者比例(主要终点)是安慰剂组的2倍多(第9-12周:Aimovig治疗组30.3%,安慰剂组13.7%,p<0.002,比值比[OR]=2.73)。除此之外,与安慰剂组相比,Aimovig治疗组在所有次要终点方面相对基线均实现了统计学意义和临床意义的改善,包括:(1)每月偏头痛天数的减少;(2)每月急性偏头痛药物使用减少;(3)每月偏头痛天数减少≥75%;(4)每月偏头痛天数减少100%;(5)采用偏头疼身体机能影响日志(MPFID)评测,身体机能得到改善,完成日常活动的能力提高。
LIBERTY研究中,Aimovig治疗组完成12周双盲治疗期的患者比例超过97%。安全性方面,治疗组未发生不良事件导致的停药,安慰剂组不良事件导致的停药比例为0.8%。LIBERTY研究的长期开放标签扩展部分正在进行中,所得数据将进一步为Aimovig用于横跨偏头痛疾病谱的疗效、安全性和耐受性提供大量证据。截至目前,该药物已在4个安慰剂对照II期和III期临床研究进行了评估,涉及患者人数超过3000例,其中一个开放标签研究持续时间长达5年。
柏林夏里特医学院医学主任Uwe Reuter教授评论称,LIBERTY研究提供了明确的证据,表明Aimovig在那些从现有预防性治疗选择中无法获得病情缓解的广大偏头痛患者中具有显著降低偏头痛发作频率并减轻相关疾病负担的能力。这些令人信服的数据,将为那些可能已经进行了多轮标准护理方案但因缺乏疗效或不耐受治疗失败的偏头痛群体带来新的希望。
偏头痛是一种常见的慢性神经血管性疾病,特征为反复发作的剧烈头痛,多为偏侧。目前,尚没有药物能够治愈偏头痛。WHO已将偏头痛指定为20个最致残的疾病之一。据估计,在全球范围内,大约90%的偏头痛患者为EM,其特征为每月偏头痛天数可多达14天;其余10%为慢性偏头痛,其特征为每月发生头痛天数至少15天,其中8天及以上为偏头痛,患者病情持续时间超过3个月。
CGRP抑制剂市场的领头羊,2022年销售额突破10亿美元
CGRP是一种神经肽,已被证明在偏头痛发作时释放,可能是偏头痛发作的诱因。目前,CGRP已成为偏头痛药物研发的热门靶点。
除了Aimovig之外,另有多家药企在开发靶向CGRP的抗体药物,包括礼来galcanezumab(每月1次)和梯瓦fremanezumab(每月1次或3月1次),这2个药物在去年10月已经提交了上市申请。此外,Alder公司的eptinezumab(3月1次)正在进行III期临床开发,该药在某些患者中应答率高达100%,有望在2018年提交上市申请。除了抗体药物之外,还有一些公司正在开发口服CGRP抑制剂,包括艾尔建的atogepant和Biohaven公司的rimegepant。
不过,在上述药物中,Aimovig将确定首先上市,成为CGRP抑制剂市场的领头羊。监管方面,美国FDA将在5月17日做出审查决定。另外,该药也正在接受欧盟EMA的审查。如果获批,Aimovig将通过自动注射笔每月一次皮下注射给药;届时,安进和诺华将在美国市场共同营销该药,安进拥有其在日本的独家商业化权利,诺华则拥有在全球其他地区的独家商业化权利。
今年3月,科睿唯安发布《2018年最值得关注的12个新药》,预测Aimovig在2022年的销售额将达到11.7亿美元,而fremanezumab凭借3月1次的优势以9.99亿美元位列第二,galcanezumab以5.46亿美元排在第三,eptinezumab以3.68亿美元位列第四。但由于强大的临床数据,eptinezumab的销售额将高速增长,2023年有望达到9.46亿美元

6 不良反应
6.1 临床试验经验
因为临床试验是在不同条件下进行,在一个药物的临床试验中观察到的不良反应率不能直接地与另一个药物的临床实验中率比较和可能不反映在临床实践中观察到率。AIMOVIG的安全曽被评价在 2,537有偏头痛患者 接受至少一剂AIMOVIG ,代表暴露的2,310患者-年。这些中,2,057患者被暴露至70 mg或140 mg每月1次共至少6个月,1,198患者被暴露共至少12个月,和287患者被暴露共至少18个月。在安慰剂-对照临床研究(研究1,2,和 3)的2个,184 患者,787患者接受至少一剂的AIMOVIG 70 mg每月1次,507患者接受至少一剂的AIMOVIG 140 mg每月1次,和890患者接受安慰剂双盲治疗3个月或6 个月期间[见临床研究(14)]。大约84%为女性,91%为白种人,和在研究纳入时均数年龄为42岁。
最常见不良反应(发生率 ≥ 3%和往往多于安慰剂)在偏头痛研究为注射部位反应和便秘。表1 总结 不良反应发生在偏头痛研究中头3个月期间(研究1,2,和3)。
AIMOVIG的安全性曽被评价在2,537患者有偏头痛接受至少一剂的AIMOVIG,代表 2,310暴露的患者-年。这些中,2,057患者被暴露。在安慰剂-对照临床研究(研究1,2,和 3)的2,184患者,787患者接受至少一剂的AIMOVIG 70 mg每月1次,507患者接受至少一剂的AIMOVIG 140 mg一月1次,和890患者接受安慰剂3个月期间或双盲治疗的6个月[见临床研究(14)]。大约84%为女性, 91%为白种人,和在研究纳入时均数年龄为42岁。
在偏头痛研究中最常见不良反应(发生率 ≥ 3%和多于安慰剂)为注射部位反应和便秘。表1 总结不良反应在偏头痛研究(研究1,2,和3)头3个月期间发生。
注射部位反应包括多种不良反应相关术语,例如注射部位疼痛和注射部位红斑。
在研究1,2,和3,用AIMOVIG治疗1.3%的患者因为不良事件是继续双盲治疗。.
最频繁注射部位反应为注射部位疼痛,注射部位红斑,和注射部位瘙痒。.
6.2 免疫原性
如同所有治疗性蛋白,存在对免疫原性潜能。抗体形成的检测,包括中和抗体,是高度依赖于分析的灵敏度和特异性。此外,在一项分析中抗体的被观察阳性发生率(包括中和抗体)可能受几种因子影响包括分析方法学,样品处置。采样时机,同时药物,和潜在疾病。因为这些理由,在下面描述研究中对erenumab-aooe抗体的发生率与其他研究或其他产品抗体的发生率的比较可能是误导。
AIMOVIG的免疫原性曽被评价利用一种免疫分析为抗-erenumab-aooe抗体结合的检测。对患者其被测试的血清阳性在筛选免疫分析,一种体外生物学分析被进行检测中和抗体。
在用AIMOVIG对照研究,抗-erenumab-aooe抗体发生的发生率为6.2% (48/778)在患者接受AIMOVIG 70 mg每月1次(其中的2人有体外中和活性)而2.6% (13/504)在患者接受AIMOVIG 140 mg每月1次(他们的无一人有体外中和活性)。中和的抗-erenumab-aooe抗体阳性率可能被低估因为分析的限制。虽然这些数据不显示证实在这些患者中一种影响抗-erenumab-aooe抗体发展对AIMOVIG疗效或安全性,可供利用数据是太限制做确定结论。
8 在特殊人群中使用
8.1 妊娠
风险总结
在妊娠妇女中没有适当数据伴随AIMOVIG的使用对发育风险。
当妊娠猴妊娠至始至终被给予erenumab-aooe没有观察到对子代不良效应(见数据)。
在妊娠猴血清erenumab-aooe暴露是大于人在临床剂量的暴露。
在美国一般人群中,重大出生缺陷和在临床上认可妊娠中流产的估算背景风险分别是2% -4%一个15% -20%。对有偏头痛妇女妇女有分娩中重大出生缺陷的估算率(2.2% -2.9%)和流产(17%)。为相似于在妇女无偏头痛报道率。
临床考虑
疾病-关联母体和/或胚胎/胎儿风险 发表文献数据曽提示妇女有偏头痛可能是处于妊娠时先兆子痫增加风险。
数据
动物数据
在一项研究其中雌性猴被给予erenumab-aooe (0或50 mg/kg)每周2次通过皮下注射妊娠至始至终(妊娠天20-22至分娩[parturition]后数周),对子代观察到无不良效应。在妊娠猴血清erenumab-aooe暴露(AUC)为在人在一个剂量140 mg每一次时的大约20倍。
8.2 哺乳
风险总结
没有在乳汁中erenumab-aooe存在的数据,对哺乳喂养婴儿的影响,或对乳汁产生影响。哺乳喂养的发育和健康的获益应与母亲对AIMOVIG的临床需求和任何潜在不良效应对哺乳喂养婴儿来自AIMOVIG或来自潜在母体条件一并考虑。
8.4 儿童使用
尚未确定在儿童患者中安全性和有效性。
8.5 老年人使用
AIMOVIG的临床研究没有包括充分数量患者年龄 65和以上以确定他们是否反应不同于较年轻患者。一般说来剂量选择对一位老年患者应被谨慎,通常地开始在剂量范围低端,反映减低的肝,肾,或心脏功能更大频数,和同时疾病或其他药物治疗。
11 描述
Erenumab-aooe 是一种人免疫球蛋白G2 (IgG2)单克隆抗体对降钙素基因-相关肽受体结合有高亲和力。Erenumab-aooe是利用重组DNA技术在中国仓鼠卵巢细胞(CHO)生产。它由2个重链组成,各含456氨基酸,和 2个轻链lambda亚类,各含216氨基酸,有一个近似分子量150 kDa。AIMOVIG(erenumab-aooe)注射液被供应作为一个无菌,无防腐剂,透明至乳白色,无色至略微浅黄色溶液为皮下给药。每1 mL单次-剂量预装自动注射器和单次-剂量预装玻璃注射器含70 mg erenumab-aooe,醋酸盐(1.5 mg),聚山梨醇80 (0.10mg),和蔗糖(73mg)。密封在自动注射器内。 密封在自动注射器内是一个单次-剂量,预装玻璃注射器。AIMOVIG的溶液有一个pH值5.2。
12 临床药理学
12.1 作用机制
Erenumab-aooe是一种人单克隆抗体结合至降钙素基因-相关肽(CGRP)受体和拮抗CGRP受体功能。
12.2 药效动力学
在一项随机化,双盲,安慰剂-对照研究在健康志愿者,同时给予erenumab-aooe (140 mg静脉,单次-剂量)与舒马曲坦(12 mg皮下,给予作为两次6 mg剂量被一小时分开)与舒马曲坦单独比较对静止血压没有影响。 AIMOVIG 是仅为皮下使用。
12.3 药代动力学
Erenumab-aooe表现出非-线性动力学作为结合至CGRP受体的结果。皮下给予一个 70mg每月一次和一个140mg每月一次剂量后在健康志愿者和偏头痛患者Cmax均数和AUClast均数被包括在表2中。低于2-倍积蓄被观察到在谷血清浓度(Cmin)对发作性和慢性偏头痛患者皮下给予 70 mg每月一次和140mg 每月一次剂量后(见表2)。血清谷浓度接近稳态至给药的3月。Erenumab-aooe的有效半衰期为28天。
作为与CGRP受体结合的结果Erenumab-aooe 表现出非-线性动力学。皮下给予一个70 mg每月1次和在表2中包括一个140 mg每月1次剂量在健康志愿者或对发作性和慢性偏头痛患者均数Cmax和AUC末次均数,观察到低于2-倍积蓄在谷血清浓度(Cmin)
偏头痛患者70 mg每月1次和140 mg每月1次剂量皮下给予剂量(见表2)。给药后至3个月血清谷浓度趋向稳态。Erenumab-aooe有效半衰期为28天。
来自一项单次-剂量研究
吸收
一个单次皮下剂量70 mg或140 mg erenumab-aooe给予至健康成年后,在接近6天达到中位峰血清浓度,和估算的绝对生物利用度为82%。
分布
一个单次140 mg静脉剂量后,末端相期间均数(SD)分布容积(Vz)被估算是3.86 (0.77)L。
代谢和排泄
对erenumab-aooe观察到两个消除相。在低浓度,消除是主要地通过饱和的结合至靶点(CGRP 受体),而较高浓度 erenumab-aooe的消除是大地通过一个非-特异性,非-饱和的蛋白溶解途径。
特殊人群
根据群体药代动力学分析erenumab-aooe的药代动力学不受年龄,性别,种族,或偏头痛谱的亚型的影响(发作性或慢性偏头痛)。
有肾或肝受损患者
来自AIMOVIG 临床研究整合数据的群体药代动力学分析没有揭示在患者有轻度或中度肾受损相对于有正常肾功能患者erenumab-aooe药代动力学一个差别。尚未曽研究有严重肾受损(eGFR < 30 mL/min/1.73 m2)患者。
未进行专门临床研究评价肝受损或肾受损对erenumab-aooe药代动力学的影响。预期肾或肝受损不影响erenumab-aooe的药代动力学。
药物相互作用研究
P450酶
Erenumab-aooe不被细胞色素P450酶代谢;所以,与细胞色素P450酶底物,诱导剂,或抑制剂的同时药物很可能没有相互作用。
口服避孕药
在一项健康女性志愿者中开放药物相互作用研究,erenumab -aooe(140 mg皮下,单-剂量)不影响一个组合口服含炔雌醇和诺孕酯的药代动力学。
舒马曲坦[Sumatriptan]
在一项健康志愿者中研究,同时给予erenumab-aooe与舒马曲坦对舒马曲坦的药代动力学没有影响[见临床药理学(12.2)]。
13 非临床毒理学
13.1 癌发生,突变发生,生育力受损
癌发生
未曽评估erenumab-aooe的癌发生潜能。
突变发生
未曽进行erenumab-aooe遗传毒理学研究。
生育力受损
未曽对erenumab-aooe进行交配研究。在猴中通过皮下注射每周2次共至6个月给予erenumab-aooe (0,25,或150 mg/kg)在雄性和雌性生殖器官中未观察到组织病理学变化。血清erenumab-aooe暴露(AUC)在较高测试剂量是多于超过100倍在人中在一个剂量140 mg每月1次。
14 临床研究
AIMOVIG的疗效被评价作为发作性或慢性偏头痛的一种预防性治疗在三项随机化,双盲,安慰剂-对照研究:两项研究在患者有发作性偏头痛(4至14 偏头痛天每月) (研究1和研究2)和一项研究在患者有慢性偏头痛(≥ 15 头痛天每月与≥ 8 偏头痛天每月)(研究3),研究纳入患者有一个偏头痛病史,有或无aura,按照头痛疾患国际分类诊断标准(ICHD -III)。
发作性偏头痛
研究1 (NCT 02456740 )是一项随机化,多中心,6-月,安慰剂-对照,双盲研究评价AIMOVIG对发作性偏头痛的预防性治疗。
总共955患者有一个发作性偏头痛病史被随机化接受或AIMOVIG 70 mg (N = 317),AIMOVIG 140 mg (N = 319),或安慰剂(N = 319)通过皮下注射每月一次(QM)共6月。研究期间患者被允许使用急性头痛治疗包括偏头痛-特异性药物(即,翠普登,麦角胺类衍生物)和NSAIDs。研究排除患者过度使用头痛药物以及患者有心肌梗死,中风。筛选前12个月内暂时性缺血发作[transient ischemic attacks],不稳定性心绞痛,冠状动脉旁路手术,或其他血管再通。主要疗效终点为均数每月偏头痛天历时月4至6从基线变化。次要终点包括均数每月偏头痛天历时月4至6(“≥ 50% MMD反应者”)从基线≥ 50%减低的实现,在均数每月急性偏头痛-特异性药物天历时月4至6从基线变化,和 均数偏头痛从基线变化。
物理功能影响每天(MPFID)历时月4至6。MPFID测量偏头痛对每天活动(EA)影响和物理受损(PI)利用一个每天电子日记。每月 MPFID评分是历时28天平均,包括天有和无偏头痛; 评分被计分从0至100。较高评分表明对EA和PI较差影响,在MPFID评分从基线减低表明改善。
总共858 (90%)患者完成6-月双-盲探究。患者有一个中位年龄42岁(范围:18至65岁),85%为女性,和89%为白种人。3%患者对偏头痛正在采用同时预防治疗。均数偏头痛频数在基线时为大约8 偏头痛天每月和跨越治疗组相似。AIMOVIG治疗与安慰剂比较显示统计学显著改善对关键疗效终点,如在表3中总结。

安进与合作伙伴诺华近日在美国洛杉矶举行的第70届美国神经病学学会(AAN)年度会议上公布了偏头痛新药Aimovig(erenumab)IIIb期临床研究LIBERTY的完整数据,该研究在既往已接受2-4种预防性药物、但因缺乏疗效或无法耐受副作用而治疗失败的发作性偏头痛(EM)患者中开展,这是一个非常独特的难治性患者群体,常常被排除在偏头痛预防性研究之外。数据证实,Aimovig在这类患者中可作为一种有效的预防性治疗选择。
Aimovig是一种单克隆抗体药物,通过靶向阻断降钙素基因相关肽(CGRP)受体来预防偏头痛,该受体被认为在偏头痛的发生中发挥了关键作用。值得一提的是,LIBERTY是首个专门在这一类难治性患者中所开展的调查靶向CGRP通路药物分子的临床研究。
LIBERTY(NCT03096834)是一项多中心、随机、双盲、安慰剂对照、12周IIIb期研究,在246例EM(定义为每月偏头痛基线天数为4-14天)患者中开展,这些患者在入组研究前已接受过2-4种预防性药物但治疗失败。研究中,患者随机分配至每月一次皮下注射Aimovig(140mg)或安慰剂,进行为期12周的双盲治疗。研究的主要终点是在双盲治疗期的最后4周(第9-12周)每月偏头痛天数从基线下降至少50%的患者比例。该研究还包括一个正在进行的为期52周的开放标签扩展期。
数据显示,Aimovig治疗组每月偏头痛天数从基线下降至少50%的患者比例(主要终点)是安慰剂组的2倍多(第9-12周:Aimovig治疗组30.3%,安慰剂组13.7%,p<0.002,比值比[OR]=2.73)。除此之外,与安慰剂组相比,Aimovig治疗组在所有次要终点方面相对基线均实现了统计学意义和临床意义的改善,包括:(1)每月偏头痛天数的减少;(2)每月急性偏头痛药物使用减少;(3)每月偏头痛天数减少≥75%;(4)每月偏头痛天数减少100%;(5)采用偏头疼身体机能影响日志(MPFID)评测,身体机能得到改善,完成日常活动的能力提高。
LIBERTY研究中,Aimovig治疗组完成12周双盲治疗期的患者比例超过97%。安全性方面,治疗组未发生不良事件导致的停药,安慰剂组不良事件导致的停药比例为0.8%。LIBERTY研究的长期开放标签扩展部分正在进行中,所得数据将进一步为Aimovig用于横跨偏头痛疾病谱的疗效、安全性和耐受性提供大量证据。截至目前,该药物已在4个安慰剂对照II期和III期临床研究进行了评估,涉及患者人数超过3000例,其中一个开放标签研究持续时间长达5年。
柏林夏里特医学院医学主任Uwe Reuter教授评论称,LIBERTY研究提供了明确的证据,表明Aimovig在那些从现有预防性治疗选择中无法获得病情缓解的广大偏头痛患者中具有显著降低偏头痛发作频率并减轻相关疾病负担的能力。这些令人信服的数据,将为那些可能已经进行了多轮标准护理方案但因缺乏疗效或不耐受治疗失败的偏头痛群体带来新的希望。
偏头痛是一种常见的慢性神经血管性疾病,特征为反复发作的剧烈头痛,多为偏侧。目前,尚没有药物能够治愈偏头痛。WHO已将偏头痛指定为20个最致残的疾病之一。据估计,在全球范围内,大约90%的偏头痛患者为EM,其特征为每月偏头痛天数可多达14天;其余10%为慢性偏头痛,其特征为每月发生头痛天数至少15天,其中8天及以上为偏头痛,患者病情持续时间超过3个月。
CGRP抑制剂市场的领头羊,2022年销售额突破10亿美元
CGRP是一种神经肽,已被证明在偏头痛发作时释放,可能是偏头痛发作的诱因。目前,CGRP已成为偏头痛药物研发的热门靶点。
除了Aimovig之外,另有多家药企在开发靶向CGRP的抗体药物,包括礼来galcanezumab(每月1次)和梯瓦fremanezumab(每月1次或3月1次),这2个药物在去年10月已经提交了上市申请。此外,Alder公司的eptinezumab(3月1次)正在进行III期临床开发,该药在某些患者中应答率高达100%,有望在2018年提交上市申请。除了抗体药物之外,还有一些公司正在开发口服CGRP抑制剂,包括艾尔建的atogepant和Biohaven公司的rimegepant。
不过,在上述药物中,Aimovig将确定首先上市,成为CGRP抑制剂市场的领头羊。监管方面,美国FDA将在5月17日做出审查决定。另外,该药也正在接受欧盟EMA的审查。如果获批,Aimovig将通过自动注射笔每月一次皮下注射给药;届时,安进和诺华将在美国市场共同营销该药,安进拥有其在日本的独家商业化权利,诺华则拥有在全球其他地区的独家商业化权利。
今年3月,科睿唯安发布《2018年最值得关注的12个新药》,预测Aimovig在2022年的销售额将达到11.7亿美元,而fremanezumab凭借3月1次的优势以9.99亿美元位列第二,galcanezumab以5.46亿美元排在第三,eptinezumab以3.68亿美元位列第四。但由于强大的临床数据,eptinezumab的销售额将高速增长,2023年有望达到9.46亿美元

6 不良反应
6.1 临床试验经验
因为临床试验是在不同条件下进行,在一个药物的临床试验中观察到的不良反应率不能直接地与另一个药物的临床实验中率比较和可能不反映在临床实践中观察到率。AIMOVIG的安全曽被评价在 2,537有偏头痛患者 接受至少一剂AIMOVIG ,代表暴露的2,310患者-年。这些中,2,057患者被暴露至70 mg或140 mg每月1次共至少6个月,1,198患者被暴露共至少12个月,和287患者被暴露共至少18个月。在安慰剂-对照临床研究(研究1,2,和 3)的2个,184 患者,787患者接受至少一剂的AIMOVIG 70 mg每月1次,507患者接受至少一剂的AIMOVIG 140 mg每月1次,和890患者接受安慰剂双盲治疗3个月或6 个月期间[见临床研究(14)]。大约84%为女性,91%为白种人,和在研究纳入时均数年龄为42岁。
最常见不良反应(发生率 ≥ 3%和往往多于安慰剂)在偏头痛研究为注射部位反应和便秘。表1 总结 不良反应发生在偏头痛研究中头3个月期间(研究1,2,和3)。
AIMOVIG的安全性曽被评价在2,537患者有偏头痛接受至少一剂的AIMOVIG,代表 2,310暴露的患者-年。这些中,2,057患者被暴露。在安慰剂-对照临床研究(研究1,2,和 3)的2,184患者,787患者接受至少一剂的AIMOVIG 70 mg每月1次,507患者接受至少一剂的AIMOVIG 140 mg一月1次,和890患者接受安慰剂3个月期间或双盲治疗的6个月[见临床研究(14)]。大约84%为女性, 91%为白种人,和在研究纳入时均数年龄为42岁。

注射部位反应包括多种不良反应相关术语,例如注射部位疼痛和注射部位红斑。
在研究1,2,和3,用AIMOVIG治疗1.3%的患者因为不良事件是继续双盲治疗。.
最频繁注射部位反应为注射部位疼痛,注射部位红斑,和注射部位瘙痒。.
6.2 免疫原性
如同所有治疗性蛋白,存在对免疫原性潜能。抗体形成的检测,包括中和抗体,是高度依赖于分析的灵敏度和特异性。此外,在一项分析中抗体的被观察阳性发生率(包括中和抗体)可能受几种因子影响包括分析方法学,样品处置。采样时机,同时药物,和潜在疾病。因为这些理由,在下面描述研究中对erenumab-aooe抗体的发生率与其他研究或其他产品抗体的发生率的比较可能是误导。
AIMOVIG的免疫原性曽被评价利用一种免疫分析为抗-erenumab-aooe抗体结合的检测。对患者其被测试的血清阳性在筛选免疫分析,一种体外生物学分析被进行检测中和抗体。
在用AIMOVIG对照研究,抗-erenumab-aooe抗体发生的发生率为6.2% (48/778)在患者接受AIMOVIG 70 mg每月1次(其中的2人有体外中和活性)而2.6% (13/504)在患者接受AIMOVIG 140 mg每月1次(他们的无一人有体外中和活性)。中和的抗-erenumab-aooe抗体阳性率可能被低估因为分析的限制。虽然这些数据不显示证实在这些患者中一种影响抗-erenumab-aooe抗体发展对AIMOVIG疗效或安全性,可供利用数据是太限制做确定结论。
8 在特殊人群中使用
8.1 妊娠
风险总结
在妊娠妇女中没有适当数据伴随AIMOVIG的使用对发育风险。
当妊娠猴妊娠至始至终被给予erenumab-aooe没有观察到对子代不良效应(见数据)。
在妊娠猴血清erenumab-aooe暴露是大于人在临床剂量的暴露。
在美国一般人群中,重大出生缺陷和在临床上认可妊娠中流产的估算背景风险分别是2% -4%一个15% -20%。对有偏头痛妇女妇女有分娩中重大出生缺陷的估算率(2.2% -2.9%)和流产(17%)。为相似于在妇女无偏头痛报道率。
临床考虑
疾病-关联母体和/或胚胎/胎儿风险 发表文献数据曽提示妇女有偏头痛可能是处于妊娠时先兆子痫增加风险。
数据
动物数据
在一项研究其中雌性猴被给予erenumab-aooe (0或50 mg/kg)每周2次通过皮下注射妊娠至始至终(妊娠天20-22至分娩[parturition]后数周),对子代观察到无不良效应。在妊娠猴血清erenumab-aooe暴露(AUC)为在人在一个剂量140 mg每一次时的大约20倍。
8.2 哺乳
风险总结
没有在乳汁中erenumab-aooe存在的数据,对哺乳喂养婴儿的影响,或对乳汁产生影响。哺乳喂养的发育和健康的获益应与母亲对AIMOVIG的临床需求和任何潜在不良效应对哺乳喂养婴儿来自AIMOVIG或来自潜在母体条件一并考虑。
8.4 儿童使用
尚未确定在儿童患者中安全性和有效性。
8.5 老年人使用
AIMOVIG的临床研究没有包括充分数量患者年龄 65和以上以确定他们是否反应不同于较年轻患者。一般说来剂量选择对一位老年患者应被谨慎,通常地开始在剂量范围低端,反映减低的肝,肾,或心脏功能更大频数,和同时疾病或其他药物治疗。
11 描述
Erenumab-aooe 是一种人免疫球蛋白G2 (IgG2)单克隆抗体对降钙素基因-相关肽受体结合有高亲和力。Erenumab-aooe是利用重组DNA技术在中国仓鼠卵巢细胞(CHO)生产。它由2个重链组成,各含456氨基酸,和 2个轻链lambda亚类,各含216氨基酸,有一个近似分子量150 kDa。AIMOVIG(erenumab-aooe)注射液被供应作为一个无菌,无防腐剂,透明至乳白色,无色至略微浅黄色溶液为皮下给药。每1 mL单次-剂量预装自动注射器和单次-剂量预装玻璃注射器含70 mg erenumab-aooe,醋酸盐(1.5 mg),聚山梨醇80 (0.10mg),和蔗糖(73mg)。密封在自动注射器内。 密封在自动注射器内是一个单次-剂量,预装玻璃注射器。AIMOVIG的溶液有一个pH值5.2。
12 临床药理学
12.1 作用机制
Erenumab-aooe是一种人单克隆抗体结合至降钙素基因-相关肽(CGRP)受体和拮抗CGRP受体功能。
12.2 药效动力学
在一项随机化,双盲,安慰剂-对照研究在健康志愿者,同时给予erenumab-aooe (140 mg静脉,单次-剂量)与舒马曲坦(12 mg皮下,给予作为两次6 mg剂量被一小时分开)与舒马曲坦单独比较对静止血压没有影响。 AIMOVIG 是仅为皮下使用。
12.3 药代动力学
Erenumab-aooe表现出非-线性动力学作为结合至CGRP受体的结果。皮下给予一个 70mg每月一次和一个140mg每月一次剂量后在健康志愿者和偏头痛患者Cmax均数和AUClast均数被包括在表2中。低于2-倍积蓄被观察到在谷血清浓度(Cmin)对发作性和慢性偏头痛患者皮下给予 70 mg每月一次和140mg 每月一次剂量后(见表2)。血清谷浓度接近稳态至给药的3月。Erenumab-aooe的有效半衰期为28天。
作为与CGRP受体结合的结果Erenumab-aooe 表现出非-线性动力学。皮下给予一个70 mg每月1次和在表2中包括一个140 mg每月1次剂量在健康志愿者或对发作性和慢性偏头痛患者均数Cmax和AUC末次均数,观察到低于2-倍积蓄在谷血清浓度(Cmin)
偏头痛患者70 mg每月1次和140 mg每月1次剂量皮下给予剂量(见表2)。给药后至3个月血清谷浓度趋向稳态。Erenumab-aooe有效半衰期为28天。
来自一项单次-剂量研究
吸收
一个单次皮下剂量70 mg或140 mg erenumab-aooe给予至健康成年后,在接近6天达到中位峰血清浓度,和估算的绝对生物利用度为82%。
分布
一个单次140 mg静脉剂量后,末端相期间均数(SD)分布容积(Vz)被估算是3.86 (0.77)L。
代谢和排泄
对erenumab-aooe观察到两个消除相。在低浓度,消除是主要地通过饱和的结合至靶点(CGRP 受体),而较高浓度 erenumab-aooe的消除是大地通过一个非-特异性,非-饱和的蛋白溶解途径。
特殊人群
根据群体药代动力学分析erenumab-aooe的药代动力学不受年龄,性别,种族,或偏头痛谱的亚型的影响(发作性或慢性偏头痛)。
有肾或肝受损患者
来自AIMOVIG 临床研究整合数据的群体药代动力学分析没有揭示在患者有轻度或中度肾受损相对于有正常肾功能患者erenumab-aooe药代动力学一个差别。尚未曽研究有严重肾受损(eGFR < 30 mL/min/1.73 m2)患者。
未进行专门临床研究评价肝受损或肾受损对erenumab-aooe药代动力学的影响。预期肾或肝受损不影响erenumab-aooe的药代动力学。
药物相互作用研究
P450酶
Erenumab-aooe不被细胞色素P450酶代谢;所以,与细胞色素P450酶底物,诱导剂,或抑制剂的同时药物很可能没有相互作用。
口服避孕药
在一项健康女性志愿者中开放药物相互作用研究,erenumab -aooe(140 mg皮下,单-剂量)不影响一个组合口服含炔雌醇和诺孕酯的药代动力学。
舒马曲坦[Sumatriptan]
在一项健康志愿者中研究,同时给予erenumab-aooe与舒马曲坦对舒马曲坦的药代动力学没有影响[见临床药理学(12.2)]。
13 非临床毒理学
13.1 癌发生,突变发生,生育力受损
癌发生
未曽评估erenumab-aooe的癌发生潜能。
突变发生
未曽进行erenumab-aooe遗传毒理学研究。
生育力受损
未曽对erenumab-aooe进行交配研究。在猴中通过皮下注射每周2次共至6个月给予erenumab-aooe (0,25,或150 mg/kg)在雄性和雌性生殖器官中未观察到组织病理学变化。血清erenumab-aooe暴露(AUC)在较高测试剂量是多于超过100倍在人中在一个剂量140 mg每月1次。
14 临床研究
AIMOVIG的疗效被评价作为发作性或慢性偏头痛的一种预防性治疗在三项随机化,双盲,安慰剂-对照研究:两项研究在患者有发作性偏头痛(4至14 偏头痛天每月) (研究1和研究2)和一项研究在患者有慢性偏头痛(≥ 15 头痛天每月与≥ 8 偏头痛天每月)(研究3),研究纳入患者有一个偏头痛病史,有或无aura,按照头痛疾患国际分类诊断标准(ICHD -III)。
发作性偏头痛
研究1 (NCT 02456740 )是一项随机化,多中心,6-月,安慰剂-对照,双盲研究评价AIMOVIG对发作性偏头痛的预防性治疗。
总共955患者有一个发作性偏头痛病史被随机化接受或AIMOVIG 70 mg (N = 317),AIMOVIG 140 mg (N = 319),或安慰剂(N = 319)通过皮下注射每月一次(QM)共6月。研究期间患者被允许使用急性头痛治疗包括偏头痛-特异性药物(即,翠普登,麦角胺类衍生物)和NSAIDs。研究排除患者过度使用头痛药物以及患者有心肌梗死,中风。筛选前12个月内暂时性缺血发作[transient ischemic attacks],不稳定性心绞痛,冠状动脉旁路手术,或其他血管再通。主要疗效终点为均数每月偏头痛天历时月4至6从基线变化。次要终点包括均数每月偏头痛天历时月4至6(“≥ 50% MMD反应者”)从基线≥ 50%减低的实现,在均数每月急性偏头痛-特异性药物天历时月4至6从基线变化,和 均数偏头痛从基线变化。
物理功能影响每天(MPFID)历时月4至6。MPFID测量偏头痛对每天活动(EA)影响和物理受损(PI)利用一个每天电子日记。每月 MPFID评分是历时28天平均,包括天有和无偏头痛; 评分被计分从0至100。较高评分表明对EA和PI较差影响,在MPFID评分从基线减低表明改善。
总共858 (90%)患者完成6-月双-盲探究。患者有一个中位年龄42岁(范围:18至65岁),85%为女性,和89%为白种人。3%患者对偏头痛正在采用同时预防治疗。均数偏头痛频数在基线时为大约8 偏头痛天每月和跨越治疗组相似。AIMOVIG治疗与安慰剂比较显示统计学显著改善对关键疗效终点,如在表3中总结。

Aimovig
Generic Name: erenumab-aooe
Dosage Form: injection
Medically reviewed by Drugs.com. Last updated on Oct 1, 2019.
Aimovig is indicated for the preventive treatment of migraine in adults.
2 DOSAGE AND ADMINISTRATION Recommended DosingThe recommended dosage of Aimovig is 70 mg injected subcutaneously once monthly. Some patients may benefit from a dosage of 140 mg injected subcutaneously once monthly.
If a dose of Aimovig is missed, administer as soon as possible. Thereafter, Aimovig can be scheduled monthly from the date of the last dose.
Important Administration InstructionsAimovig is for subcutaneous use only.
The needle shield within the white or orange cap of the Aimovig prefilled autoinjector and gray needle cap of the Aimovig prefilled syringe contain dry natural rubber (a derivative of latex), which may cause allergic reactions in individuals sensitive to latex.
Aimovig is intended for patient self-administration. Prior to use, provide proper training to patients and/or caregivers on how to prepare and administer Aimovig using the single-dose prefilled autoinjector or single-dose prefilled syringe, including aseptic technique [see Instructions for Use]:
Prior to subcutaneous administration, allow Aimovig to sit at room temperature for at least 30 minutes protected from direct sunlight [see How Supplied/Storage and Handling (16.2)]. Do not warm by using a heat source such as hot water or a microwave.Do not shake the product.Inspect visually for particulate matter and discoloration prior to administration [see Dosage Forms and Strengths (3)]. Do not use if the solution is cloudy or discolored or contains flakes or particles.Administer Aimovig in the abdomen, thigh, or upper arm subcutaneously. Do not inject into areas where the skin is tender, bruised, red, or hard.Both prefilled autoinjector and prefilled syringe are single-dose and deliver the entire contents. 3 DOSAGE FORMS AND STRENGTHSAimovig is a sterile, clear to opalescent, colorless to light yellow solution available as follows:
Injection: 70 mg/mL in a single-dose prefilled SureClick autoinjectorAimovig is contraindicated in patients with serious hypersensitivity to erenumab-aooe or to any of the excipients. Reactions have included anaphylaxis and angioedema [see Warnings and Precautions (5.1)].
5 WARNINGS AND PRECAUTIONS Hypersensitivity ReactionsHypersensitivity reactions, including rash, angioedema, and anaphylaxis, have been reported with Aimovig in postmarketing experience. Most hypersensitivity reactions were not serious and occurred within hours of administration, although some occurred more than one week after administration. If a serious or severe hypersensitivity reaction occurs, discontinue administration of Aimovig and initiate appropriate therapy [see Contraindications (4), and Patient Counseling Information (17)].
Constipation with Serious ComplicationsConstipation with serious complications has been reported following the use of Aimovig in the postmarketing setting. There were cases that required hospitalization, including cases where surgery was necessary. In a majority of these cases, the onset of constipation was reported after the first dose of Aimovig; however, patients have also presented with constipation later on in treatment. Aimovig was discontinued in most reported cases of constipation with serious complications. Constipation was one of the most common (up to 3%) adverse reactions reported in clinical studies [see Adverse Reactions (6.1)].
Monitor patients treated with Aimovig for severe constipation and manage as clinically appropriate [see Patient Counseling Information (17)]. The concurrent use of medications associated with decreased gastrointestinal motility may increase the risk for more severe constipation and the potential for constipation-related complications.
6 ADVERSE REACTIONSThe following serious adverse reactions are described below and elsewhere in the labeling:
Hypersensitivity Reactions [see Warnings and Precautions (5.1)]Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
The safety of Aimovig has been evaluated in 2537 patients with migraine who received at least one dose of Aimovig, representing 2310 patient-years of exposure. Of these, 2057 patients were exposed to 70 mg or 140 mg once monthly for at least 6 months, 1198 patients were exposed for at least 12 months, and 287 patients were exposed for at least 18 months.
In placebo-controlled clinical studies (Studies 1, 2, and 3) of 2184 patients, 787 patients received at least one dose of Aimovig 70 mg once monthly, 507 patients received at least one dose of Aimovig 140 mg once monthly, and 890 patients received placebo during 3 months or 6 months of double-blind treatment [see Clinical Studies (14)]. Approximately 84% were female, 91% were white, and the mean age was 42 years at study entry.
The most common adverse reactions (incidence ≥ 3% and more often than placebo) in the migraine studies were injection site reactions and constipation. Table 1 summarizes the adverse reactions that occurred during the first 3 months in the migraine studies (Studies 1, 2, and 3).

a Injection site reactions include multiple adverse reactions related terms, such as injection site pain and injection site erythema. |
In Studies 1, 2, and 3, 1.3% of patients treated with Aimovig discontinued double-blind treatment because of adverse events. The most frequent injection site reactions were injection site pain, injection site erythema, and injection site pruritus.
ImmunogenicityAs with all therapeutic proteins, there is potential for immunogenicity. The detection of antibody formation, including neutralizing antibodies, is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to erenumab-aooe in the studies described below with the incidence of antibodies in other studies or to other products may be misleading.
The immunogenicity of Aimovig has been evaluated using an immunoassay for the detection of binding anti-erenumab-aooe antibodies. For patients whose sera tested positive in the screening immunoassay, an in vitro biological assay was performed to detect neutralizing antibodies.
In controlled studies with Aimovig, the incidence of anti-erenumab-aooe antibody development was 6.2% (48/778) in patients receiving Aimovig 70 mg once monthly (2 of whom had in vitro neutralizing activity) and 2.6% (13/504) in patients receiving Aimovig 140 mg once monthly (none of whom had in vitro neutralizing activity). The neutralizing anti-erenumab-aooe antibody positive rate may be underestimated because of limitations of the assay. Although these data do not demonstrate an impact of anti-erenumab-aooe antibody development on the efficacy or safety of Aimovig in these patients, the available data are too limited to make definitive conclusions.
Postmarketing ExperienceThe following adverse reactions have been identified during postapproval use of Aimovig. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Skin and Appendages: Hypersensitivity reactions, including rash, angioedema, and anaphylaxis [see Warnings and Precautions (5.1)].
Gastrointestinal Disorders: Constipation with serious complications [see Warnings and Precautions (5.2)].
8 USE IN SPECIFIC POPULATIONS PregnancyRisk Summary
There are no adequate data on the developmental risk associated with the use of Aimovig in pregnant women. No adverse effects on offspring were observed when pregnant monkeys were administered erenumab-aooe throughout gestation [see Data]. Serum erenumab-aooe exposures in pregnant monkeys were greater than those in humans at clinical doses.
In theU.S.general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2%-4% and 15%-20%, respectively. The estimated rate of major birth defects (2.2%-2.9%) and miscarriage (17%) among deliveries to women with migraine are similar to rates reported in women without migraine.
Clinical Considerations
Disease-Associated Maternal and/or Embryo/Fetal Risk
Published data have suggested that women with migraine may be at increased risk of preeclampsia during pregnancy.
Data
Animal Data
In a study in which female monkeys were administered erenumab-aooe (0 or 50 mg/kg) twice weekly by subcutaneous injection throughout pregnancy (gestation day 20-22 to parturition), no adverse effects on offspring were observed. Serum erenumab-aooe exposures (AUC) in pregnant monkeys were approximately 20 times that in humans at a dose of 140 mg once monthly.
LactationRisk Summary
There are no data on the presence of erenumab-aooe in human milk, the effects on the breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Aimovig and any potential adverse effects on the breastfed infant from Aimovig or from the underlying maternal condition.
Pediatric UseSafety and effectiveness in pediatric patients have not been established.
Geriatric UseClinical studies of Aimovig did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
11 DESCRIPTIONErenumab-aooe is a human immunoglobulin G2 (IgG2) monoclonal antibody that has high affinity binding to the calcitonin gene-related peptide receptor. Erenumab-aooe is produced using recombinant DNA technology in Chinese hamster ovary (CHO) cells. It is composed of 2 heavy chains, each containing 456 amino acids, and 2 light chains of the lambda subclass, each containing 216 amino acids, with an approximate molecular weight of 150 kDa.
Aimovig (erenumab-aooe) injection is supplied as a sterile, preservative-free, clear to opalescent, colorless to light yellow solution for subcutaneous administration. Each 1 mL 70 mg single-dose prefilled autoinjector and 70 mg single-dose prefilled glass syringe contains 70 mg erenumab-aooe, acetate (1.5 mg), polysorbate 80 (0.10 mg), and sucrose (73 mg). Each 1 mL 140 mg single-dose prefilled autoinjector and 140 mg single-dose prefilled glass syringe contains 140 mg erenumab-aooe, acetate (2.0 mg), polysorbate 80 (0.10 mg), and sucrose (65 mg). Enclosed within the autoinjector is a single-dose, prefilled glass syringe. The solution of Aimovig has a pH of 5.2.
12 CLINICAL PHARMACOLOGY Mechanism of ActionErenumab-aooe is a human monoclonal antibody that binds to the calcitonin gene-related peptide (CGRP) receptor and antagonizes CGRP receptor function.
PharmacodynamicsIn a randomized, double-blind, placebo-controlled study in healthy volunteers, concomitant administration of erenumab-aooe (140 mg intravenous, single-dose) with sumatriptan (12 mg subcutaneous, given as two 6 mg doses separated by one hour) had no effect on resting blood pressure compared with sumatriptan alone. Aimovig is for subcutaneous use only.
PharmacokineticsErenumab-aooe exhibits non-linear kinetics as a result of binding to the CGRP receptor. The Cmax mean and AUClast mean following subcutaneous administration of a 70 mg once monthly and a 140 mg once monthly dose in healthy volunteers or migraine patients are included in Table 2.
Less than 2-fold accumulation was observed in trough serum concentrations (Cmin) for episodic and chronic migraine patients following subcutaneous administration of 70 mg once monthly and 140 mg once monthly doses (see Table 2). Serum trough concentrations approached steady state by 3 months of dosing. The effective half-life of erenumab-aooe is 28 days.

Absorption
Following a single subcutaneous dose of 70 mg or 140 mg erenumab-aooe administered to healthy adults, median peak serum concentrations were attained in approximately 6 days, and estimated absolute bioavailability was 82%.
Distribution
Following a single 140 mg intravenous dose, the mean (SD) volume of distribution during the terminal phase (Vz) was estimated to be 3.86 (0.77) L.
Metabolism and Excretion
Two elimination phases were observed for erenumab-aooe. At low concentrations, the elimination is predominantly through saturable binding to target (CGRP receptor), while at higher concentrations the elimination of erenumab-aooe is largely through a non-specific, non-saturable proteolytic pathway.
Specific Populations
The pharmacokinetics of erenumab-aooe were not affected by age, gender, race, or subtypes of migraine spectrum (episodic or chronic migraine) based on population pharmacokinetics analysis.
Patients with Renal or Hepatic Impairment
Population pharmacokinetic analysis of integrated data from the Aimovig clinical studies did not reveal a difference in the pharmacokinetics of erenumab-aooe in patients with mild or moderate renal impairment relative to those with normal renal function. Patients with severe renal impairment (eGFR < 30 mL/min/1.73 m2) have not been studied. No dedicated clinical studies were conducted to evaluate the effect of hepatic impairment or renal impairment on the pharmacokinetics of erenumab-aooe. Renal or hepatic impairment is not expected to affect pharmacokinetics of erenumab-aooe.
Drug Interaction Studies
P450 Enzymes
Erenumab-aooe is not metabolized by cytochrome P450 enzymes; therefore, interactions with concomitant medications that are substrates, inducers, or inhibitors of cytochrome P450 enzymes are unlikely.
Oral Contraceptives
In an open-label drug interaction study in healthy female volunteers, erenumab-aooe (140 mg subcutaneous, single-dose) did not affect the pharmacokinetics of a combined oral contraceptive containing ethinyl estradiol and norgestimate.
Sumatriptan
In a study in healthy volunteers, concomitant administration of erenumab-aooe with sumatriptan had no effect on the pharmacokinetics of sumatriptan [see Clinical Pharmacology (12.2)].
13 NONCLINICAL TOXICOLOGY Carcinogenesis, Mutagenesis, Impairment of FertilityCarcinogenesis
The carcinogenic potential of erenumab-aooe has not been assessed.
Mutagenesis
Genetic toxicology studies of erenumab-aooe have not been conducted.
Impairment of Fertility
Mating studies have not been conducted on erenumab-aooe. No histopathological changes in male or female reproductive organs were observed in monkeys administered erenumab-aooe (0, 25, or 150 mg/kg) by subcutaneous injection twice weekly for up to 6 months. Serum erenumab-aooe exposures (AUC) at the higher dose tested were more than 100 times that in humans at a dose of 140 mg once monthly.
14 CLINICAL STUDIESThe efficacy of Aimovig was evaluated as a preventive treatment of episodic or chronic migraine in three randomized, double-blind, placebo-controlled studies: two studies in patients with episodic migraine (4 to 14 migraine days per month) (Study 1 and Study 2) and one study in patients with chronic migraine (≥ 15 headache days per month with ≥ 8 migraine days per month) (Study 3). The studies enrolled patients with a history of migraine, with or without aura, according to the International Classification of Headache Disorders (ICHD-III) diagnostic criteria.
Episodic Migraine
Study 1 (NCT 02456740) was a randomized, multi-center, 6-month, placebo-controlled, double-blind study evaluating Aimovig for the preventive treatment of episodic migraine. A total of 955 patients with a history of episodic migraine were randomized to receive either Aimovig 70 mg (N = 317), Aimovig 140 mg (N = 319), or placebo (N = 319) by subcutaneous injection once monthly (QM) for 6 months. Patients were allowed to use acute headache treatments including migraine-specific medications (i.e., triptans, ergotamine derivatives) and NSAIDs during the study.
The study excluded patients with medication overuse headache as well as patients with myocardial infarction, stroke, transient ischemic attacks, unstable angina, coronary artery bypass surgery, or other revascularization procedures within 12 months prior to screening.
The primary efficacy endpoint was the change from baseline in mean monthly migraine days over months 4 to 6. Secondary endpoints included the achievement of a ≥ 50% reduction from baseline in mean monthly migraine days over months 4 to 6 (“≥ 50% MMD responders”), the change from baseline in mean monthly acute migraine-specific medication days over months 4 to 6, and the change from baseline in mean Migraine Physical Function Impact Diary (MPFID) over months 4 to 6. The MPFID measures the impact of migraine on everyday activities (EA) and physical impairment (PI) using an electronic diary administered daily. Monthly MPFID scores are averaged over 28 days, including days with and without migraine; scores are scaled from 0 to 100. Higher scores indicate worse impact on EA and PI. Reductions from baseline in MPFID scores indicate improvement.
A total of 858 (90%) patients completed the 6-month double-blind study. Patients had a median age of 42 years (range: 18 to 65 years), 85% were female, and 89% were white. Three percent of patients were taking concomitant preventive treatments for migraine. The mean migraine frequency at baseline was approximately 8 migraine days per month and was similar across treatment groups.
Aimovig treatment demonstrated statistically significant improvements for key efficacy endpoints compared to placebo, as summarized in Table 3.

Compared to placebo, patients treated with Aimovig 70 mg once monthly and 140 mg once monthly showed greater reductions from baseline in mean monthly MPFID everyday activity scores averaged over months 4 to 6 [difference from placebo: -2.2 for Aimovig 70 mg and -2.6 for Aimovig 140 mg; p-value < 0.001 for both], and in mean monthly MPFID physical impairment scores averaged over months 4 to 6 [difference from placebo: -1.9 for Aimovig 70 mg and -2.4 for Aimovig 140 mg; p-value < 0.001 for both].
Study 2 (NCT 02483585) was a randomized, multi-center, 3-month, placebo-controlled, double-blind study evaluating Aimovig for the preventive treatment of episodic migraine. A total of 577 patients with a history of episodic migraine were randomized to receive either Aimovig 70 mg (N = 286) or placebo (N = 291) by subcutaneous injection once monthly for 3 months. Patients were allowed to use acute headache treatments including migraine-specific medications (i.e., triptans, ergotamine derivatives) and NSAIDs during the study.
The study excluded patients with medication overuse headache as well as patients with myocardial infarction, stroke, transient ischemic attacks, unstable angina, coronary artery bypass surgery, or other revascularization procedures within 12 months prior to screening.
The primary efficacy endpoint was the change from baseline in monthly migraine days at month 3. Secondary endpoints included the achievement of a ≥ 50% reduction from baseline in monthly migraine days (“≥ 50% MMD responders”), the change from baseline in monthly acute migraine-specific medication days at month 3, and the proportion of patients with at least a 5-point score reduction from baseline in MPFID at month 3.
A total of 546 (95%) patients completed the 3-month double-blind study. Patients had a median age of 43 years (range: 18 to 65 years), 85% were female, and 90% were white. Six to seven percent of patients were taking concomitant preventive migraine treatment. The mean migraine frequency at baseline was approximately 8 migraine days per month and was similar between treatment groups.
Aimovig treatment demonstrated statistically significant improvements for key efficacy endpoints compared to placebo, as summarized in Table 4.

The pre-specified analysis for the MPFID was based on at least a 5-point reduction within-patient responder definition. Aimovig 70 mg once monthly was not significantly better than placebo for the proportion of responders for everyday activity [difference from placebo: 4.7%; odds ratio = 1.2; p-value = 0.26] and physical impairment [difference from placebo: 5.9%; odds ratio = 1.3; p-value = 0.13]. In an exploratory analysis of the change from baseline in the mean MPFID scores at month 3, patients treated with Aimovig 70 mg, as compared to placebo, showed nominally greater reductions of physical impairment scores [difference from placebo: -1.3; p-value = 0.021], but not of everyday activities scores [difference from placebo: -1.1; p-value = 0.061].
Chronic Migraine
Study 3 (NCT 02066415) was a randomized, multi-center, 3-month, placebo-controlled, double-blind study evaluating Aimovig as a preventive treatment of chronic migraine. A total of 667 patients with a history of chronic migraine with or without aura were randomized to receive Aimovig 70 mg (N = 191), Aimovig 140 mg (N = 190), or placebo (N = 286) by subcutaneous injections once monthly for 3 months. Patients were allowed to use acute headache treatments including migraine-specific medications (i.e., triptans, ergotamine derivatives) and NSAIDs during the study.
The study excluded patients with medication overuse headache caused by opiate overuse and patients with concurrent use of migraine preventive treatments. Patients with myocardial infarction, stroke, transient ischemic attacks, unstable angina, coronary artery bypass surgery, or other revascularization procedures within 12 months prior to screening were also excluded.
The primary efficacy endpoint was the change from baseline in monthly migraine days at month 3. Secondary endpoints included the achievement of a ≥ 50% reduction from baseline in monthly migraine days (“≥ 50% MMD responders”) and change from baseline in monthly acute migraine-specific medication days at month 3.
A total of 631 (95%) patients completed the 3-month double-blind study. Patients had a median age of 43 years (range: 18 to 66 years), 83% were female, and 94% were white. The mean migraine frequency at baseline was approximately 18 migraine days per month and was similar across treatment groups.
Aimovig treatment demonstrated statistically significant improvements for key efficacy outcomes compared to placebo, as summarized in Table 5.
