[完整处方资料]
1 适应症和用途
FYCOMPA(perampanel)适用于为治疗在有癫痫年龄12岁和以上部分性癫痫发作有或无继发性全身性癫痫患者作为辅助治疗。
2 剂量和给药方法
2.1 给药资料
在缺乏酶-诱导抗癫痫药物
FYCOMPA的推荐开始剂量为2 mg每天1次睡前口服。增加剂量 by 每天2 mg增量不频于每周至剂量4 mg 至8 mg每天1次睡前服用。在老年患者中,在点滴增加期间建议剂量增加不频于每2周。
推荐剂量范围8 mg至12 mg每天1次。剂量12 mg每天1次导致比剂量8 mg每天1次有些更大减低癫痫发作率,但有重大增加不良反应。个体给药应根据临床反应和耐受性调整[见临床研究(14)]。
存在酶-诱导抗癫痫药物
存在酶-诱导抗癫痫药物,包括苯妥英,卡马西平,和奥卡西平时,FYCOMPA的推荐开始剂量是4 mg和应密切监视患者反应。临床试验揭示在这些患者中对癫痫发作率效应重大减低。在12 mg比在8 mg癫痫发作频数的减低有些更大。[见临床研究(14)].
当这些酶-诱导抗癫痫药物从患者治疗方案被引入或撤销时。应严密监视患者临床反应和耐受性。可能需要调整FYCOMPA剂量。
2.2 在有肝受损患者中剂量调整
根据在有轻度和中度肝受损患者中perampanel的暴露较高和半衰期较长,建议调整剂量。开始剂量应为每天2 mg与每周增量每2周每天2 mg直至实现目标剂量。对轻度肝受损患者最大推荐每天剂量为6 mg和对中度肝受损患者4 mg。在有轻度和中度肝受损患者中剂量增加,如同所有患者,应根据临床反应和耐受性。严重肝受损患者使用没有建议[见特殊人群中使用(8.6),临床药理学(12.3)]。
2.3 有肾受损患者
在中度肾受损患者可使用FYCOMPA与密切监视。可考虑根据临床反应和耐受性缓慢点滴调整。不建议在患者有严重肾受损或进行血液透析患者中使用[见特殊人群中使用(8.7),临床药理学(12.3)]。

5 警告和注意事项
5.1 严重精神和行为反应
在对照3期癫痫临床试验中,随机化至接受FYCOMPA在8 mg和12 mg/day剂量患者, 分别发生敌意-和攻击性-相关不良反应12%和20%,与之比较安慰剂组患者6%。这些效应是剂量相关和一般在治疗的头6周内出现,虽然通过37周以上继续观察到新事件。FYCOMPA-治疗患者经受更多敌意-和攻击性相关严重不良反应,和导致比安慰剂-治疗患者更频繁剂量减低,中断,和终止。
一般说来,在安慰剂-对照3期癫痫试验中,正在用FYCOMPA治疗患者比正在服安慰剂患者神经精神病事件报道更频。这些事件包括易怒,攻击性,愤怒,和焦虑,perampanel治疗患者发生2%或更多和频数为安慰剂-治疗患者2倍。观察到用perampanel治疗比用安慰剂更常见的其他症状,包括好战,影响不稳定性, 激动,和身体攻击。这些事件的有些被报道为严重和危及生命。在对照和开放研究,包括非-癫痫研究3/4,368例perampanel-治疗患者表现出杀人意念或威胁。
在3期癫痫试验中,这些事件发生在有和无既往精神病史,无既往攻击性行为,或同时使用伴敌意和攻击性药物的患者。有些患者经历其预先存在精神病情况的变坏。临床试验排除有活动性精神病和不稳定复发性情感性精神障碍患者。酒精和perampanel的联用显著恶化情绪和增加愤怒[见药物相互作用(7.3)]。服用FYCOMPA患者应避免使用酒精。在健康志愿者服用FYCOMPA,观察到精神病事件包括偏执狂,欣快情绪, 激动,愤怒,精神状态改变,和定向障碍/混乱状态。
在perampanel-治疗受试者的非-癫痫试验,精神病事件的发生比安慰剂-治疗受试者更常见包括定向障碍,妄想,和偏执狂。
应告知患者,其照顾者,和家庭FYCOMPA可能增加精神病事件的风险。FYCOMPA的治疗期间和末次给药后至少1个月应监视患者,和特别是当服用较高剂量和药物治疗的最初几周时(点滴调整剂量期)或在剂量增加的其他时间。如这些症状发生应减低FYCOMPA的剂量。对持续严重或精神症状或行为恶化和转介精神病评估。
5.2 自杀行为和意念
为任何适应症服用抗癫痫药物,包括FYCOMPA患者,增加自杀的想法或行为风险。为任何适应症用抗癫痫药物治疗的患者应监视抑郁,自杀想法或行为,和/或在情绪或行为中任何不寻常变化的出现或恶化。
11种不同抗癫痫药物的199项安慰剂-对照临床试验(单-和辅助治疗)的合并分析显示患者随机化至抗癫痫药物之一与随机化至安慰剂患者比较有自杀想法或行为约2倍风险(调整后相对风险1.8,95% CI:1.2,2.7)。在这些试验中,中位治疗时间12周,在27,863例抗癫痫药物-治疗患者中自杀行为或意念的估计发生率为0.43%,与之比较16,029例安慰剂-治疗患者中为0.24%,代表对每530例被治疗患者增加约1例被治疗自杀想法或行为。在本试验药物-治疗患者有四例自杀和安慰剂-治疗患者中无,但数量太小不允许得出药物对自杀影响的任何结论。
早在开始用抗癫痫药物治疗1周后和持续在评估治疗期间观察到用抗癫痫药物增加自杀的想法或行为的风险。因为包括在此分析是大多数试验没有延伸超过24周,不能评估超过24周自杀想法或行为的风险。
在被分析数据中自杀的想法或行为的风险药物中一般一致。用不同作用机制和跨越范围适应症抗癫痫药物风险增加的发现提示风险应用于所有对任何适应症使用的抗癫痫药物。在被分析临床试验中年龄(5-100岁) 风险没有非常重大变化。
表1显示按适应症对抗癫痫药物所有评价的绝对和相对风险。
为癫痫临床试验中比在临床试验为精神病或其它情况比较,自杀想法或行为相对风险较高,但为癫痫和精神病适应症绝对风险差别相似。.
任何人考虑开FYCOMPA处方或任何其他抗癫痫药物必须平衡自杀的想法或行为风险与为治疗疾病的风险。癫痫和抗癫痫药物被处方许多其他疾病伴随发病率和死亡率和自杀想法和行为风险增加。治疗期间应出现自杀想法和行为,处分者需要考虑在任何给予患者是否出现这些症状可能与被治疗疾病相关。
应告知患者,其照顾者,和家庭抗癫痫药物增加自杀想法和行为的风险和应劝告需要警惕抑郁体征和症状的出现和恶化,任何情绪和行为不寻常变化,或自杀想法,行为或自伤的想法的出现。应立即向卫生保健提供者报告担忧的行为。
5.3 神经系统的影响
头晕和步态不稳
FYCOMPA引起剂量相关事件与头晕和步态障碍或协调有关增加[见不良反应(6.1)]。在对照3期癫痫临床试验中,随机化至接受剂量8 mg和12 mg/day的FYCOMPA患者中,报道头晕和眩晕分别35%和47%,与之比较安慰剂-治疗患者10%。随机化至接受剂量8 mg和12 mg/day的FYCOMPA患者中步态不稳相关事件(包括共济失调,步态不稳,平衡障碍,和协调异常)分别报道12%和16%,相比较安慰剂-治疗患者2%。
这些不良反应的发生大多数在剂量点滴调整时和导致perampanel-治疗受试者3%终止相比较安慰剂-治疗患者为1%,老年患者与较年轻成年和青少年这些不良反应风险增加。
睡意和疲乏
FYCOMPA引起剂量依赖性增加睡意和疲乏-相关事件(包括疲乏,虚弱,和嗜眠)。
在对照3期癫痫临床试验中,随机化至接受FYCOMPA患者剂量8 mg和12 mg/day,分别16%和18%报道睡意 相比安慰剂患者7%。在对照3期癫痫临床试验中,随机化至接受FYCOMPA患者剂量8 mg和12 mg/day,分别报道疲乏-相关事件12%和15%相比安慰剂患者为5%。Perampanel-治疗患者睡意或疲乏-相关事件导致终止2%而安慰剂-治疗患者0.5%。老年患者与较年轻成年和青少年比较这些不良反应风险增加。
风险改善
处方者应劝告患者不从事需要精神警觉的危险活动例如操作机械车辆或危险的机械,直至已知FYCOMPA效应。
在对照3期癫痫临床试验中这些不良反应大多数发生在剂量点滴调整期。
5.4 跌交
正在用FYCOMPA治疗患者中(有和无同时癫痫发作)跌交风险增加,有些病例导致严重损伤包括头损伤和骨折。在对照3期癫痫临床试验中,随机化至接受FYCOMPA患者剂量8 mg和12 mg/day,分别报道跌交5%和10%,相比较安慰剂-治疗患者为3%。FYCOMPA-治疗患者比安慰剂-治疗患者被报道跌交严重和导致终止更频。老年患者与较年轻成年和青少年比较跌交风险增加。
5.5 撤销抗癫痫药物
患者有癫痫发作疾病中当突然撤销抗癫痫药物时癫痫发作频数有增加潜能。FYCOMPA的半衰期约105小时 从而即使突然中断,血水平逐渐下降。在抗-癫痫临床试验FYCOMPA被撤销没有下降点滴调整。虽然终止后少量患者表现出癫痫发作,数据不够充分不允许提出关于适当撤药方案的任何建议。一般地建议用抗癫痫药物一个逐渐撤药,但如撤药是对不良事件反应,可考虑迅速撤药。
6 不良反应
在处方资料的其他章节更详细讨论以下不良反应:
● 严重精神和行为反应[见警告和注意事项(5.1)]
● 自杀行为和意念[见警告和注意事项(5.2)]
● 头晕和步态不稳[见警告和注意事项(5.3)]
● 睡意和疲乏[见警告和注意事项(5.3)]
● 跌交[见警告和注意事项(5.4)]
6.1 临床试验经验
因为临床试验是在广泛不同情况下进行的,临床试验观察到不良反应率不能与另一种药临床试验发生率直接比较而且可能不反映实践中观察到的发生率。
在有部分癫痫发作患者的3期安慰剂对照研究(研究1,2,和3)合并分析中总共1,038例患者用perampanel(2,4,8,或12 mg每天1次)构成安全性人群。 约51%患者为女性和平均年龄为35岁。
不良反应导致终止
在对照3期临床试验(研究1,2,和3),作为不良反应的结果,随机化至接受FYCOMPA患者在推荐剂量4 mg,8 mg和12 mg/day,终止率分别为3%,8%和19%而随机化接受安慰剂患者为5%[见临床研究(14)]。导致终止最常见不良事件(在8 mg或12 mg FYCOMPA组≥1%并大于安慰剂)为头晕,睡意,眩晕,攻击性, 愤怒,共济失调,视力模糊,易怒,和构音障碍[见警告和注意事项(5.1和5.3)]。
最常见不良反应
表2给出了在3期对照试验中(研究1,2,和3),在任何有部分性癫痫发作患者FYCOMPA剂量组发生≥2%的不良反应的发生率。总体而言,最频报道剂量-相关不良反应in患者接受FYCOMPA剂量8 mg或12 mg(≥4%和发生至少1%和高于安慰剂组)包括头晕(36%), 睡意(16%),疲乏(10%),易怒(9%),跌交(7%),恶心(7%),共济失调(5%),平衡障碍(4%),步态不稳(4%),眩晕(4%),和体重增加(4%)。对于几乎每种不良反应,用12 mg发生率较高和以上常导致剂量减低或终止。
体重增加
在成年中使用FYCOMPA曾观察到体重增加。
在对照3期癫痫临床试验中,FYCOMPA-治疗成年增量平均1.1 kg (2.5磅)与在安慰剂-治疗成年比较平均0.3 kg(0.7 lbs)与中位暴露19周。FYCOMPA-治疗患者增量至少分别其基线体重的7%和15%,增量成年百分率分别9.1%和0.9%,当安慰剂-治疗患者比较分别4.5%和0.2%。建议临床监视体重。
性别和种族的比较
在不良反应发生率中未注意到明显性别差异。
虽然有少数非-高加索患者,与高加索患者比较未观察到不良反应发生率差别。
7 药物相互作用S
7.1 避孕药
剂量12 mg/dayFYCOMPA与避孕药同时使用时减低左炔诺孕酮[levonorgestrel]暴露约40%[见临床药理学(12.3)]。FYCOMPA与口服或植入含左炔诺孕酮避孕药使用可能使避孕药疗效较低。建议另外非激素型避孕。
7.2 细胞色素P450(CYP)诱导剂
已知CYP酶诱导剂与FYCOMPA的同时使用包括卡马西平,苯妥英,或奥卡西平减低perampanel的血浆水平约50~67%[见临床药理学(12.3)]。存在酶-诱导抗癫痫药物时FYCOMPA应被增加[见剂量和给药方法(2.1)]。
当这些酶-诱导抗癫痫药物被引入患者的治疗方案或从方案撤销时,应严密监视患者临床反应和耐受性。可能需要调整FYCOMPA剂量。但是,如上所述, 对同时治疗患者中见到治疗效应减低,不受使用较高剂量(8 mg至12 mg)影响[见剂量和给药方法(2.1)]。
应避免FYCOMPA与其他强CYP3A诱导剂(如,利福平,圣约翰草)的同时使用。
7.3 酒精和其他 CNS抗抑郁药
FYCOMPA和CNS抗抑郁药包括酒精同时使用may增加CNS抑郁。在健康受试者中一项药效动力学相互作用研究发现FYCOMPA对复杂工作的影响例如驾驶能力是与酒精损伤效应相加或超过-相加作用[见临床药理学(12.3)]。FYCOMPA 12 mg/day多次给药也增强酒精干扰警觉性和戒心作用,和愤怒,混乱,和抑郁增加的水平。当FYCOMPA与其他CNS抗抑郁药联用时也可见这些效应。当FYCOMPA与这些药物给予时也应小心。与CNS抗抑郁药同时使用(如苯二氮卓类,麻醉药,巴比妥类,镇静作用的抗组胺类)患者活动应被限制直至已经受。劝告患者不要驾驶或操作机械直至他们对FYCOMPA得到充分经验调整是否不良地影响这些活动。
8 特殊人群中使用
8.1 妊娠
妊娠类别C
在妊娠妇女中没有适当和对照良好研究。在动物研究中,在妊娠大鼠和兔在临床上相关剂量perampanel诱发发育毒性。妊娠期间只有如潜在效益胜过对胎儿潜在风险时才应使用FYCOMPA。
在器官形成期自始至终Perampanel的口服给药(1,3,or 10 mg/kg/day)至妊娠大鼠,在所有受试剂量导致内脏异常(小肠憩室)增加。在一项剂量范围研究在较高口服剂量(10,30,或60 mg/kg/day),在中和高受试剂量观察到胚胎致死性和减低胎儿体重。最低试验剂量(1 mg/kg/day)根据体表面积(mg/m2)相似于人剂量8 mg/day。
器官形成期自始至终Perampanel的口服给药(1,3,或10 mg/kg/day)至妊娠兔,在中和高受试剂量观察到胚胎致死性;对兔中胚胎-胎儿发育毒性的无效应剂量(1 mg/kg/day)根据体表面积(mg/m2)是人剂量8 mg/day 约2倍。
怀孕和哺乳自始至终口服给药Perampanel(1,3,或10 mg/kg/day)至大鼠在中和高受试剂量导致胎鼠和幼畜死亡和在最高受试剂量在雄性和雌性中延迟性成熟。在子代中未观察到神经行为或生殖功能测量效应。根据体表面积(mg/m2)对大鼠围产期发育毒性无效应剂量(1 mg/kg/day)相似于人剂量8 mg/day。
妊娠注册
提供关于子宫内暴露于FYCOMPA效应的信息,医生被劝告建议服用FYCOMPA妊娠患者纳入北美抗癫痫药物(NAAED)妊娠注册。
8.3 哺乳母亲
Perampanel和/或其代谢物被排泄至大鼠乳汁,和被检测浓度高于母体血浆。不知道药物是否排泄在人乳汁。因为许多药物被排泄在人乳汁,当FYCOMPA被给予哺乳妇女应谨慎对待。
8.4 儿童使用
通过三项随机化,双盲,安慰剂-对照,多中心研究包括12和16岁间的72例儿童患者暴露于perampanel确定FYCOMPA对部分性癫痫发作辅助治疗的t安全性和疗效[见临床研究(14.1),临床药理学(12.3)]。尚未确定在<12岁患儿中FYCOMPA的安全性和有效性。
幼动物数据
Perampanel的口服给药(1,3,3/10/30 mg/kg/day;在产后天[PND]28和56天增至高剂量)至幼大鼠共12周在PND 7天开始导在中和高剂量致体重减轻,生长减慢,神经行为受损(水迷宫性能和听力惊跳习惯),在高剂量延缓性成熟。在所有剂量观察到CNS体征(鉴定活动性, 不协调,过度照料/抓),幼畜死亡,后肢张开减少,和后肢的握力下降。给药停止后对幼畜体重,幼畜生长后肢张开水迷宫性能受损和听力惊跳习惯效应持续。
在这项研究中没有确定对产后发育毒性的无效应剂量。
Perampanel的口服给药(1,5,5/10 mg/kg/day;在产后PND 56天高剂量增加)至幼犬共33周,在PND 42天开始,在所有受试剂量导致CNS体征(不协调,过度照料/舔/抓,空间定向障碍,和/或共济失调步态)。
8.5 老年人使用
FYCOMPA的临床研究没有包括包括足够数量年龄65岁和以上患者以确定FYCOMPA在老年人群中的安全性和疗效。因为在老年人中给药点滴调整增加不良反应可能性,在年龄65岁和以上患者应缓慢地点滴调整剂量[见剂量和给药方法(2.1)]。
8.6 有肝受损患者
有严重肝受损患者中不建议使用FYCOMPA和在患者有轻度或中度肝受损建议调整剂量[见剂量和给药方法(2.2),临床药理学(12.3)]。
8.7 有肾受损患者
在有轻度肾受损患者中不需要调整剂量。有中度肾受损患者使用FYCOMPA应谨慎和可能考虑缓慢点滴调整剂量。严重肾受损患者或患者进行血液透析不建议使用[见剂量和给药方法(2.3),临床药理学(12.3)]。
9 药物滥用和依赖性
9.1 受控物质
FYCOMPA含perampanel,(方案将在DEA审评后确定)。
9.2 滥用
处方药物滥用是故意的非治疗性使用的药物,即使一次,为其有益心理学或生理学作用。药物成瘾,其发展经历反复药物滥用,其特点是强烈愿望某药尽管有害后果,难以控制其使用,给予较高优先使用药物而不是义务,耐受性增加,和有时出现戒断身体依赖性。药物滥用和药物成瘾是独立的和不同于身体依赖性(例如,滥用可能不伴有身体依赖性)[见药物滥用和依赖性(9.3)]。
进行研究人滥用潜能评价FYCOMPA(8 mg,24 mg,和36 mg滥用潜能) 在娱乐的多种药物使用者中与阿普唑仑[alprazolam] C-IV (1.5 mg和3 mg),和口服氯胺酮[ketamine]C-III(100 mg)比较。超治疗剂量的FYCOMPA 24和36 mg产生对“欣快症”反应相似于氯胺酮100 mg和阿普唑仑3 mg。用视觉模拟评分法(VAS)对“高” FYCOMPA 24 mg和36 mg产生反应与氯胺酮100 mg有可比性和显著较高于两中剂量阿普唑仑。“喜欢药物[Drug Liking]”,“整体药物喜好[Overall Drug Liking]”,和“复吸[Take Drug Again]” 对FYCOMPA是各自统计学上较低于氯胺酮100mg。此外,对“不喜爱作用[Bad Drug Effects]”,FYCOMPA 24 mg和36 mg 产生反应显著较高于氯胺酮100mg。对“镇静[Sedation]” FYCOMPA 24和36 mg产生反应相似于阿普唑仑3 mg和较高于氯胺酮100 mg。
此外,用视觉模拟评分法测量与解离现象相关测量例如“漂浮[Floating]”,“魂不守舍[Spaced Out]”和“分离[Detached],”FYCOMPA在超治疗剂量产生反应相似于氯胺酮100 mg和大于两种剂量受试的阿普唑仑。值得注意的是,由于睡意一些受试者FYCOMPA的Tmax附近有丢失数据。上面描述数据可能过低估计FYCOMPA的作用。较高剂量FYCOMPA对大多数测量的影响时间比阿普唑仑3 mg和氯胺酮100 mg长得多。.
在本研究中, FYCOMPA给予8 mg,24 mg和36 mg后欣快症发生率分别是37%,46%,46%,高于阿普唑仑3 mg (13%)但低于氯胺酮100 mg (89%)。
9.3 依赖性
身体依赖性特征是突然终止或显著减低某药剂量后的戒断症状。
尚未适当评价FYCOMPA产生戒断症状的潜能。
10 药物过量
10.1 在人中急性过量的征象,症状,和实验室发现
用FYCOMPA过量临床经验有限。报道的最高过量(约264 mg)是故意的。这例患者经受精神状态,激动,和攻击性行为改变的严重不良反应和恢复无后遗症。一般说来,伴过量不良反应是与治疗剂量反应最频繁报道头晕相似。无报道的后遗症。
10.2 过量的治疗和处理
对FYCOMPA的过量反应不能得到特异性解毒剂。在过量事件中,应使用任何过量标准的处理。建议应确保适当保持气道,给氧,和通气;监视心律和生命标志测量。应联系经过认证的毒物控制中性为更新处理过量FYCOMPA的信息。由于其长半衰期,被FYCOMPA引起的反应可能延长,
11 一般描述
FYCOMPA片含perampanel,一种非竞争性AMPA受体拮抗剂。Perampanel在化学上被描述为 2-(2-oxo-1-phenyl-5-pyridin-2-yl-1,2-dihydropyridin-3-yl) benzonitrile hydrate (4:3)。
分子式为C23H15N3O • 3/4H2O和分子量362.90 (3/4水)。化学结构式如下:
溶于乙腈和丙酮,略溶于甲醇,乙醇和乙酸乙酯,非常略微溶于1-辛醇和乙醚和几乎不溶于庚烷和水。
FYCOMPA (perampanel)片是圆形,双凸,薄膜包衣片含 2 mg,4 mg,6 mg,8 mg,10 mg或12 mg的perampanel.片含下列无活性成分:一水乳糖,低取代羟丙基纤维素,聚维酮,微晶纤维素,硬脂酸镁,羟丙甲纤维素,聚乙二醇,滑石和不同强度的氧化钛片还可能含黄色三氧化二铁(10 mg和2 mg),氧化铁红(2 mg,4 mg,6 mg,8 mg),黑色氧化铁(8 mg)和FD&C 蓝色 # 2靛蓝胭脂红铝色淀(10 mg和12 mg)。
12 临床药理学
12.1 作用机制
Perampanel是一种在突触后神经元上of the离子型α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)谷氨酸盐受体的非竞争性拮抗剂。谷氨酸盐是中枢神经系统中主要的兴奋性神经递质和被神经元过度兴奋引起的一些神经学疾病中有牵连。FYCOMPA在人中发挥其抗癫痫作用的精细机制尚未完全阐明。
12.2 药效动力学
精神运动性能
延长QT间期潜能, 在一项健康受试者安慰剂-对照perampanel对QT彻底研究,没有证据表明perampanel在剂量6或12 mg (即,对最大安慰剂调整基线-校正QTc是低于10 msec的95%可信区间上限)引起临床意义的QT间期延长。在本研究中观察到用12 mg剂量暴露没有覆盖有肝受损患者服用剂量超过6 mg/day期望的暴露。在最大推荐剂量(12 mg),perampanel不延长QTc间期至任何临床上相关程度。
12.3 药代动力学
健康受试者和有部分性癫痫发作患者Perampanel的药代动力学相似。Perampanel的半衰期约105小时,使约在2-3周达到稳态。单次给予0.2–12 mg的Perampanel后和每天1次多次给予1-12 mg后,AUC以剂量-正比例方式增加。
吸收
口服给药后Perampanel被迅速和完全吸收与可忽略的首过代谢。在空腹条件下中位Tmax范围从0.5至2.5小时。食物不影响吸收的程度(AUC),但减慢吸收的速率。在进食条件下,perampanel的Cmax与空腹条件比较减低28-40%和Tmax延迟2-3小时。
分布
来自体外 研究数据表明,在浓度范围20至2000 ng/mL,perampanel约95-96%结合至血浆蛋白,主要结合至白蛋白和α1-酸性糖蛋白。Perampanel的血液与血浆比值为0.55-0.59。
代谢
Perampanel通过原发氧化和相继葡萄糖醛酸化被广泛地代谢。根据体外 研究用重组人CYPs和人肝微粒体的结果氧化代谢是通过CYP3A4和/或CYP3A5介导的。也可能涉及其他CYP 酶。
给予放射性标记 perampanel后,在全身循环中未变化perampanel占总放射性74-80%,而在血浆中检测到只有痕量个体perampanel代谢物。
消除
放射性标记perampanel给予8例健康老年受试者后,在尿中回收22%给予放射性和在粪中48%。在尿和粪中,回收的放射性主要是氧化和结合代谢物的混合物组成。来自19项报道的1期研究合并数据的群体药代动力学分析perampanel的t1/2平均为105小时。健康受试者和患者的Perampanel表观清除率约为12 mL/min。
特殊人群
肝受损
在12例有轻度和中度肝受损(分别Child-Pugh A和B)受试者与12例人口统计指标匹配的健康受试者比较,在单次1 mg剂量后评价Perampanel的药代动力学。与其健康对照比较有轻度肝受损受试者中总体(游离和蛋白结合)perampanel的暴露(AUC0-inf)是较大50%和有中度肝受损受试者中高于两倍(2.55-倍)。有轻度和中度肝受损受试者的游离perampanel的AUC0-inf分别为匹配健康对照的1.8-倍和3.3-倍。轻度受损受试者T1/2延长(306相比125小时)和中度受损(295相比139小时)。未曾在有严重肝受损受试者中研究Perampanel[见剂量和给药方法(2.2),特殊人群中使用(8.6)]。
肾受损
在有肾受损患者中尚未进行专门研究评价Perampanel的药代动力学。用来自在安慰剂-对照临床试验有部分性癫痫发作和接受FYCOMPA直至12 mg/day患者的合并数据进行群体药代动力学分析。结果显示在有轻度肾受损患者(肌酐清除率50-80 mL/min)与有正常肾功能患者(肌酐清除率 > 80 mL/min)比较perampanel表观清除率减低27%,与AUC相应增加37%。考虑到正常和轻度受损患者间暴露的重大重叠,对有轻度肾受损患者无需剂量调整。尚未在有严重肾受损患者和进行血液透析患者中进行Perampanel研究[见剂量和给药方法(2.3),特殊人群中使用(8.7)]。
性别
在安慰剂-对照临床试验中有部分性癫痫发作接受FYCOMPA患者的群体药代动力学分析,在女性中perampanel表观清除率(0.605 L/hr)是低于男性(0.730 L/hr)17%。无需根据性别调整剂量。
儿童患者
尚未在<12岁患儿中研究FYCOMPA,在有部分性癫痫发作患者年龄范围从12至74岁接受FYCOMPA的安慰剂对照试验,在一项群体药代动力学分析,在青少年(0.787 L/hr)中perampanel的表观清除率是略微,但不显著,较高于成年。儿童患者高于12岁可相似于成年给药。
老年人
在安慰剂-对照试验,有部分性癫痫发作患者的群体药代动力学分析年龄范围从12至74岁接受FYCOMPA 未发现年龄对perampanel表观清除率的明显影响[见剂量和给药方法(2.1),特殊人群中使用(8.5)]。
种族
在安慰剂对照试验中,有部分性癫痫发作患者的群体药代动力学分析包括576例高加索人,14例黑人,97例非-中国亚裔,和62例中国人接受FYCOMPA,未发现种族对perampanel表观清除率明显影响。无需剂量调整。
药物相互作用研究
体外药物相互作用的评估
药物代谢酶
在人肝微粒体中,perampanel浓度30 μmol/L,大约在12 mg剂量稳态Cmax的10倍,对CYP2C8,CYP3A4,UGT1A9和UGT2B7有弱抑制作用。Perampanel在浓度30 μmol/L不抑制CYP1A2,CYP2A6,CYP2C9,CYP2C19,CYP2D6,CYP2E1,UGT1A1,UGT1A4和UGT1A6。
在培养人肝细胞中,与阳性对照比较(包括苯巴比妥和利福平),发现perampanel弱诱导CYP2B6(30μmol/L)和CYP3A4/5(≥ 3μmol/L)。Perampanel还诱导UGT1A1(≥ 3μmol/L)和UGT1A4 (30μmol/L)。在浓度直至30 μmol/L时Perampanel不诱导CYP1A2。
转运蛋白
体外研究显示perampanel不是以下的底物或显著抑制剂:有机阴离子转运多肽1B1和1B3;有机阴离子转运蛋白1,2,3,和4:有机阳离子转运蛋白1,2,和3;流出转运蛋白P-糖蛋白和乳腺癌耐药蛋白。
体外药物相互作用的评估
与抗癫痫药物药物相互作用
同时抗癫痫药物对FYCOMPA的影响:
卡马西平. 作为一种CYP酶诱导剂,卡马西平增加perampanel清除率。给予卡马西平在300 mg BID健康受试者稳态时分别减低单次2 mg剂量perampanel的Cmax和AUC0-inf为26%和67%。Perampanel的t1/2从56.8小时被缩短至25小时。在临床研究检查部分性癫痫发作,一项群体药代动力学分析显示用卡马西平患者perampanel的AUC与不用酶-诱导抗癫痫药物患者AUC比较被减低67%[见剂量和给药方法(2.1),药物相互作用(7.2)]。
奥卡西平. 在临床研究检查部分性癫痫发作,一项群体药代动力学分析显示用奥卡西平患者与不用酶-诱导抗癫痫药物患者比较perampanel的AUC减低一半[见剂量和给药方法(2.1),药物相互作用(7.2)]。
苯妥英. 在临床研究检查部分性癫痫发作,一项群体药代动力学分析显示用苯妥英患者与不用酶-诱导抗癫痫药物患者比较perampanel AUC减低一半[见剂量和给药方法(2.1),药物相互作用(7.2)]。
苯巴比妥和普里米酮:在一项有部分性发作癫痫患者群体药代动力学分析,在临床试验(37例患者与苯巴比妥共同给药和9例患者与普里米酮共同给药)未发现对perampanel AUC显著影响。不能除外苯巴比妥和普里米酮对perampanel 浓度轻微影响。
托吡酯[Topiramate]:在有部分性癫痫发作临床试验患者的群体药代动力学分析显示用托吡酯患者与不用酶-诱导抗癫痫药物患者比较perampanel AUC减低约20%。
其他抗癫痫药物:在临床试验有部分性癫痫发作患者的群体药代动力学分析显示氯巴占[clobazam],氯硝西泮[clonazepam],拉莫三嗪[lamotrigine],左乙拉西坦[levetiracetam],丙戊酸钠[valproate],和唑尼沙胺[zonisamide]对perampanel的清除率没有影响。
其他强CYP3A诱导剂(如,利福平,圣约翰草)也可能大大增加perampanel的清除率和减低perampanel血浆浓度[见药物相互作用(7.2)]。
FYCOMPA对同时抗癫痫药物的影响:
根据在有部分性癫痫发作患者临床试验的一项群体药代动力学分析,FYCOMPA直至12 mg/day不显著影响氯硝西泮,左乙拉西坦, 苯巴比妥,苯妥英,托吡酯,或唑尼沙胺的清除率。FYCOMPA对卡马西平,氯巴占,拉莫三嗪,和拉莫三嗪的清除率有统计意义的影响,但在最高perampanel剂量评价(12 mg/day)时这些药物清除率中的增加各小于10%。
FYCOMPA共同给药导致奥卡西平清除率减低26%和增加其浓度。未测定奥卡西平的活性代谢物10-单羟基代谢物(MHD)浓度。
与其他药物-药物相互作用研究
其他药物对FYCOMPA的影响
酮康唑[Ketoconazole]. 健康受试者of 单次1-mg剂量perampanel与酮康唑剂量400 mg每天1次,一种强 CYP3A4抑制剂共同给药共8天延长perampanel t1/2为15%(67.8相比58.4小时)和增加AUC0-inf 为20%。
口服避孕药.当单次6-mg剂量perampanel被给予健康女性受试者含炔雌醇 30 μg和左炔诺孕酮150 μg口服避孕药21-天疗程后,Perampanel Cmax和AUC0-72h 没有改变。
FYCOMPA对其他药物的影响
咪达唑仑[Midazolam]. 在健康受试者中Perampanel给予6 mg每天1次doses共20天分别减低咪达唑仑(一种 CYP3A4底物)的AUC0-inf和Cmax为13%和15%。
口服避孕药. 在健康女性受试者中Perampanel 4 mg每天1次与一种含炔雌醇 30 μg和左炔诺孕酮150 μg口服避孕药共同给药共21天不改变或炔雌醇或左炔诺孕酮的Cmax或AUC0-24h。在另一研究中,在健康女性中FYCOMPA 12 mg或8 mg每天1次给药后21-天给予单剂量口服避孕药。FYCOMPA在12 mg不改变炔雌醇的AUC0-24h但减低其Cmax为18%,和也减低左炔诺孕酮的Cmax和AUC0-24h分别为42%和40%。FYCOMPA 在8 mg对或炔雌醇或左炔诺孕酮的Cmax或AUC0-24h没有显著影响,对左炔诺孕酮AUC0-24h有小(9%)减低[见药物相互作用(7.1)]。
左旋多巴Levodopa. 健康受试者给予Perampanel 4 mg每天1次剂量共19天对左旋多巴的Cmax和AUC0-inf 无影响。

生育能力
在雄性和雌性大鼠中交配前和自始至终以及雌性继续至怀孕第6天给予perampanel(口服剂量1,10,或30 mg/kg/day),对生育能力无明显作用。在所有剂量,但特别是在最高受试剂量观察到动情周期延长和/或不规则。在所有剂量血浆perampanel暴露(AUC)是低于人给予 8 mg/day时的暴露。
14 临床研究
在3项随机化, 双盲,安慰剂-对照,多中心试验(研究1,2,和3)在成年和青少年患者(年龄12岁和以上),在部分性癫痫发作,有或无继发全身化,与1至3种同时抗癫痫药物没有适当控制患者中研究FYCOMPA的疗效。所有试验有一个初始6-周基线阶段,为了随机化在这个期间患者被要求有有5次以上癫痫发作。基线阶段接着是19周治疗阶段包括6周点滴调整剂量期和一个13周维持期。在这些3试验中患者有癫痫平均时间约21年和基线癫痫发作中位频数范围从9.3至14.3次发作每28天。试验期间,85%以上患者正在服用2至3种同时使用抗癫痫药物有或无同时迷走神经刺激,和约50% 是用至少一种抗癫痫药物已知诱导CYP3A4,一种FYCOMPA代谢关键的酶(即卡马西平,奥卡西平,或苯妥英),导致显著减低FYCOMPA的血清浓度[见药物相互作用(7.2),临床药理学(12.3)]。
每项研究评价安慰剂和多次FYCOMPA剂量(见图1)。所有3项试验在剂量点滴调整期时,用FYCOMPA患者接受一个初始2 mg每天1次剂量,随后剂量增加以每周每天2 mg增量至最后目标剂量。经受不能耐受 不良反应患者被允许其剂量减低至以前可耐受剂量。
研究1,2,和3中主要终点是治疗期时每28天癫痫发作频数当与基线期时比较的变化百分率。统计显著性的标准是p<0.05。表3显示这些研究的结果。在剂量每天4至12 mg时观察到癫痫发作率统计意义的减低。在4至8 mg时剂量反应明显;在剂量每天12 mg时频数的额外减低很小。
表4代表来自所有3项研究合并数据的分析,患者根据是或不同时使用抗癫痫药物诱导剂(卡马西平,奥卡西平,或苯妥英)分组。分析揭示在存在诱导剂重大减低效应。
图1显示跨越所有三项试验在维持治疗期超过基线有不同百分率减低患者的比例。癫痫发作频数增加患者被显示在左侧“更坏”柱中。在其余五类别患者的癫痫发作频数减低。从而,对安慰剂,4,8,和12 mg,癫痫发作频数有40至<60%减低的患者百分率分别为13.2%,17.4%,19.0%,和15.8%。

Fycompa
Generic Name: perampanel
Dosage Form: tablets, oral suspension
Last updated on May 1, 2019.
WARNING: SERIOUS PSYCHIATRIC AND BEHAVIORAL REACTIONS
· Serious or life-threatening psychiatric and behavioral adverse reactions including aggression, hostility, irritability, anger, and homicidal ideation and threats have been reported in patients taking Fycompa (5.1).
· These reactions occurred in patients with and without prior psychiatric history, prior aggressive behavior, or concomitant use of medications associated with hostility and aggression (5.1).
· Advise patients and caregivers to contact a healthcare provider immediately if any of these reactions or changes in mood, behavior, or personality that are not typical for the patient are observed while taking Fycompa or after discontinuing Fycompa (5.1).
· Closely monitor patients particularly during the titration period and at higher doses (5.1).
· Fycompa should be reduced if these symptoms occur and should be discontinued immediately if symptoms are severe or are worsening (5.1).
1 INDICATIONS AND USAGE1.1 Partial-Onset Seizures
Fycompa is indicated for the treatment of partial-onset seizures with or without secondarily generalized seizures in patients with epilepsy 4 years of age and older.
1.2 Primary Generalized Tonic-Clonic SeizuresFycompa is indicated as adjunctive therapy for the treatment of primary generalized tonic-clonic seizures in patients with epilepsy 12 years of age and older.
Fycompa Dosage and Administration2.1 Dosage for Partial-Onset SeizuresMonotherapy or Adjunctive Therapy
The recommended starting dosage of Fycompa in adults and pediatric patients 4 years of age and older is 2 mg once daily taken orally at bedtime. Increase dosage no more frequently than at weekly intervals by increments of 2 mg once daily based on individual clinical response and tolerability.
The recommended maintenance dose range is 8 mg to 12 mg once daily, although some patients may respond to a dose of 4 mg daily. A dose of 12 mg once daily resulted in somewhat greater reductions in seizure rates than the dose of 8 mg once daily, but with a substantial increase in adverse reactions.
Dosage adjustment is recommended with concomitant use of moderate or strong CYP3A4 enzyme inducing drugs, which include certain antiepileptic drugs (AEDs) [see Dosage and Administration (2.3)].
2.2 Dosage for Primary Generalized Tonic-Clonic SeizuresAdjunctive Therapy
The recommended starting dosage of Fycompa in adults and pediatric patients 12 years of age and older is 2 mg once daily taken orally at bedtime. Increase dosage no more frequently than at weekly intervals by increments of 2 mg once daily based on individual clinical response and tolerability.
The recommended maintenance dose is 8 mg once daily taken at bedtime. Patients who are tolerating Fycompa at 8 mg once daily and require further reduction of seizures may benefit from a dose increase up to 12 mg once daily if tolerated.
Dosage adjustment is recommended with concomitant use of moderate or strong CYP3A4 enzyme inducing drugs, which include certain AEDs [see Dosage and Administration (2.3)].
2.3 Dosage Modifications with Concomitant Use of Moderate or Strong CYP3A4 Enzyme InducersModerate and strong CYP3A4 inducers, including enzyme-inducing AEDs such as phenytoin, carbamazepine, and oxcarbazepine, cause a reduction in Fycompa plasma levels [see Drug Interactions (7.2), Clinical Pharmacology (12.3)]. Therefore, in adults and pediatric patients 4 years of age and older receiving these concomitant enzyme-inducing drugs, the recommended starting dosage of Fycompa is 4 mg once daily taken orally at bedtime.
Increase dosage by increments of 2 mg once daily based on individual clinical response and tolerability, no more frequently than at weekly intervals. A maintenance dose has not been established in clinical trials. The highest dose studied in patients on concomitant enzyme-inducing AEDs was 12 mg once daily.
When moderate or strong CYP3A4 inducers are introduced or withdrawn from a patient’s treatment regimen, the patient should be closely monitored for clinical response and tolerability. Dose adjustment of Fycompa may be necessary.
2.4 Dosage Adjustment in Patients with Hepatic ImpairmentIn patients with mild and moderate hepatic impairment, the starting dose of Fycompa is 2 mg once daily. Increase dosage by increments of 2 mg once daily no more frequently than every 2 weeks. The maximum recommended daily dose is 6 mg for patients with mild hepatic impairment and 4 mg for patients with moderate hepatic impairment. Fycompa is not recommended for use in patients with severe hepatic impairment [see Use in Specific Populations (8.6), Clinical Pharmacology (12.3)].
2.5 Dosage Information for Patients with Renal ImpairmentFycompa can be used in patients with moderate renal impairment with close monitoring. A slower titration may be considered, based on clinical response and tolerability. Fycompa is not recommended in patients with severe renal impairment or patients undergoing hemodialysis [see Use in Specific Populations (8.7), Clinical Pharmacology (12.3)].
2.6 Dosage Information for Elderly PatientsIn elderly patients, increase dosage no more frequently than every 2 weeks during titration [see Use in Specific Populations (8.5)].
2.7 Administration of Oral SuspensionFycompa oral suspension, 0.5 mg/mL, should be shaken well before every administration. The provided adapter and graduated oral dosing syringe should be used to administer the oral suspension. A household teaspoon or tablespoon is not an adequate measuring device. The adapter, which is supplied in the product carton, should be inserted firmly into the neck of the bottle before use and remain in place for the duration of the usage of the bottle. The dosing syringe should be inserted into the adapter and the dose withdrawn from the inverted bottle. The cap should be replaced after each use. The cap fits properly when the adapter is in place [see Instructions for Use].
Discard any unused Fycompa oral suspension remaining 90 days after first opening the bottle.

5 WARNINGS AND PRECAUTIONS5.1 Serious Psychiatric and Behavioral ReactionsIn the controlled partial-onset seizure clinical trials, hostility- and aggression-related adverse reactions occurred in 12% and 20% of patients randomized to receive Fycompa at doses of 8 mg and 12 mg per day, respectively, compared to 6% of patients in the placebo group. These effects were dose-related and generally appeared within the first 6 weeks of treatment, although new events continued to be observed through more than 37 weeks. Fycompa-treated patients experienced more hostility- and aggression-related adverse reactions that were serious, severe, and led to dose reduction, interruption, and discontinuation more frequently than placebo-treated patients.
In general, in placebo-controlled partial-onset seizure clinical trials, neuropsychiatric events were reported more frequently in patients being treated with Fycompa than in patients taking placebo. These events included irritability, aggression, anger, and anxiety, which occurred in 2% or greater of Fycompa-treated patients and twice as frequently as in placebo-treated patients. Other symptoms that occurred with Fycompa and were more common than with placebo included belligerence, affect lability, agitation, and physical assault. Some of these events were reported as serious and life-threatening. Homicidal ideation and/or threat were exhibited in 0.1% of 4,368 Fycompa-treated patients in controlled and open label trials, including non-epilepsy trials. Homicidal ideation and/or threat have also been reported postmarketing in patients treated with Fycompa.
In the partial-onset seizure clinical trials, these events occurred in patients with and without prior psychiatric history, prior aggressive behavior, or concomitant use of medications associated with hostility and aggression. Some patients experienced worsening of their pre-existing psychiatric conditions. Patients with active psychotic disorders and unstable recurrent affective disorders were excluded from the clinical trials. The combination of alcohol and Fycompa significantly worsened mood and increased anger. Patients taking Fycompa should avoid the use of alcohol [see Drug Interactions (7.3)].
Similar serious psychiatric and behavioral events were observed in the primary generalized tonic-clonic seizure clinical trial.
In healthy volunteers taking Fycompa, observed psychiatric events included paranoia, euphoric mood, agitation, anger, mental status changes, and disorientation/confusional state.
In the non-epilepsy trials, psychiatric events that occurred in perampanel-treated patients more often than placebo-treated patients included disorientation, delusion, and paranoia.
In the postmarketing setting, there have been reports of psychosis (acute psychosis, hallucinations, delusions, paranoia) and delirium (delirium, confusional state, disorientation, memory impairment) in patients treated with Fycompa [see Adverse Reactions (6.2)].
Patients, their caregivers, and families should be informed that Fycompa may increase the risk of psychiatric events. Patients should be monitored during treatment and for at least 1 month after the last dose of Fycompa, and especially when taking higher doses and during the initial few weeks of drug therapy (titration period) or at other times of dose increases. Dose of Fycompa should be reduced if these symptoms occur. Permanently discontinue Fycompa for persistent severe or worsening psychiatric symptoms or behaviors and refer for psychiatric evaluation.
5.2 Suicidal Behavior and IdeationAntiepileptic drugs (AEDs), including Fycompa, increase the risk of suicidal thoughts or behavior in patients taking these drugs for any indication. Patients treated with any AED for any indication should be monitored for the emergence or worsening of depression, suicidal thoughts or behavior, and/or any unusual changes in mood or behavior.
Pooled analyses of 199 placebo-controlled clinical trials (mono- and adjunctive therapy) of 11 different AEDs showed that patients randomized to one of the AEDs had approximately twice the risk (adjusted Relative Risk 1.8, 95% CI: 1.2, 2.7) of suicidal thinking or behavior compared to patients randomized to placebo. In these trials, which had a median treatment duration of 12 weeks, the estimated incidence of suicidal behavior or ideation among 27,863 AED-treated patients was 0.43%, compared to 0.24% among 16,029 placebo-treated patients, representing an increase of approximately one case of suicidal thinking or behavior for every 530 patients treated. There were four suicides in drug-treated patients in the trials and none in placebo-treated patients, but the number is too small to allow any conclusion about drug effect on suicide.
The increased risk of suicidal thoughts or behavior with AEDs was observed as early as 1 week after starting drug treatment with AEDs and persisted for the duration of treatment assessed. Because most trials included in the analysis did not extend beyond 24 weeks, the risk of suicidal thoughts or behavior beyond 24 weeks could not be assessed.
The risk of suicidal thoughts or behavior was generally consistent among drugs in the data analyzed. The finding of increased risk with AEDs of varying mechanisms of action and across a range of indications suggests that the risk applies to all AEDs used for any indication. The risk did not vary substantially by age (5-100 years) in the clinical trials analyzed.
Table 1 shows absolute and relative risk by indication for all evaluated AEDs.

The relative risk for suicidal thoughts or behavior was higher in clinical trials for epilepsy than in clinical trials for psychiatric or other conditions, but the absolute risk differences were similar for the epilepsy and psychiatric indications.
Anyone considering prescribing Fycompa or any other AED must balance the risk of suicidal thoughts or behavior with the risk of untreated illness. Epilepsy and many other illnesses for which AEDs are prescribed are themselves associated with morbidity and mortality and an increased risk of suicidal thoughts and behavior. Should suicidal thoughts and behavior emerge during treatment, the prescriber needs to consider whether the emergence of these symptoms in any given patient may be related to the illness being treated.
5.3 Neurologic EffectsDizziness and Gait Disturbance
Fycompa caused dose-related increases in events related to dizziness and disturbance in gait or coordination [see Adverse Reactions (6.1)]. In the controlled partial-onset seizure clinical trials, dizziness and vertigo were reported in 35% and 47% of patients randomized to receive Fycompa at doses of 8 mg and 12 mg per day, respectively, compared to 10% of placebo-treated patients. The gait disturbance related events (including ataxia, gait disturbance, balance disorder, and abnormal coordination) were reported in 12% and 16% of patients randomized to receive Fycompa at doses of 8 mg and 12 mg per day, respectively, compared to 2% of placebo-treated patients. Elderly patients had an increased risk of these adverse reactions compared to younger adults and pediatric patients.
These adverse reactions occurred mostly during the titration phase and led to discontinuation in 3% of Fycompa-treated patients compared to 1% of placebo-treated patients.
These adverse reactions were also observed in the primary generalized tonic-clonic seizure clinical trial.
Somnolence and Fatigue
Fycompa caused dose-dependent increases in somnolence and fatigue-related events (including fatigue, asthenia, and lethargy).
In the controlled partial-onset seizure clinical trials, 16% and 18% of patients randomized to receive Fycompa at doses of 8 mg and 12 mg per day, respectively, reported somnolence compared to 7% of placebo patients. In the controlled partial-onset seizure clinical trials, 12% and 15% of patients randomized to receive Fycompa at doses of 8 mg and 12 mg per day, respectively, reported fatigue-related events compared to 5% of placebo patients. Somnolence or fatigue-related events led to discontinuation in 2% of Fycompa-treated patients and 0.5% of placebo-treated patients. Elderly patients had an increased risk of these adverse reactions compared to younger adults and pediatric patients.
In the controlled partial-onset seizure clinical trials, these adverse reactions occurred mostly during the titration phase.
These adverse reactions were also observed in the primary generalized tonic-clonic seizure clinical trial.
Risk Amelioration
Prescribers should advise patients against engaging in hazardous activities requiring mental alertness, such as operating motor vehicles or dangerous machinery, until the effect of Fycompa is known. Patients should be carefully observed for signs of central nervous system (CNS) depression, such as somnolence and sedation, when Fycompa is used with other drugs with sedative properties because of potential additive effects.
5.4 FallsAn increased risk of falls, in some cases leading to serious injuries including head injuries and bone fracture, occurred in patients being treated with Fycompa (with and without concurrent seizures). In the controlled partial-onset seizure clinical trials, falls were reported in 5% and 10% of patients randomized to receive Fycompa at doses of 8 mg and 12 mg per day, respectively, compared to 3% of placebo-treated patients. Falls were reported as serious and led to discontinuation more frequently in Fycompa-treated patients than placebo-treated patients. Elderly patients had an increased risk of falls compared to younger adults and pediatric patients.
5.5 Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS)/Multiorgan HypersensitivityDrug Reaction with Eosinophilia and Systemic Symptoms (DRESS), also known as Multiorgan hypersensitivity, has been reported in patients taking antiepileptic drugs, including Fycompa. DRESS may be fatal or life-threatening. DRESS typically, although not exclusively, presents with fever, rash, lymphadenopathy, and/or facial swelling, in association with other organ system involvement, such as hepatitis, nephritis, hematological abnormalities, myocarditis, or myositis sometimes resembling an acute viral infection. Eosinophilia is often present. Because this disorder is variable in its expression, other organ systems not noted here may be involved. It is important to note that early manifestations of hypersensitivity, such as fever or lymphadenopathy, may be present even though rash is not evident. If such signs or symptoms are present, the patient should be evaluated immediately. Fycompa should be discontinued if an alternative etiology for the signs or symptoms cannot be established.
5.6 Withdrawal of Antiepileptic DrugsThere is the potential of increased seizure frequency in patients with seizure disorders when antiepileptic drugs are withdrawn abruptly. Fycompa has a half-life of approximately 105 hours so that even after abrupt cessation, blood levels fall gradually. In epilepsy clinical trials Fycompa was withdrawn without down-titration. Although a small number of patients exhibited seizures following discontinuation, the data were not sufficient to allow any recommendations regarding appropriate withdrawal regimens. A gradual withdrawal is generally recommended with antiepileptic drugs, but if withdrawal is a response to adverse events, prompt withdrawal can be considered.

6.1 Clinical Trials ExperienceBecause 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.
Partial-Onset Seizures
Adult and Adolescent Patients (12 years of age and older)
A total of 1,038 patients receiving Fycompa (2, 4, 8, or 12 mg once daily) constituted the safety population in the pooled analysis of the placebo-controlled trials (Studies 1, 2, and 3) in patients with partial-onset seizures. Approximately 51% of patients were female, and the mean age was 35 years.
Adverse Reactions Leading to Discontinuation
In controlled clinical trials (Studies 1, 2, and 3), the rate of discontinuation as a result of an adverse reaction was 3%, 8%, and 19% in patients randomized to receive Fycompa at the recommended doses of 4 mg, 8 mg, and 12 mg per day, respectively, and 5% in patients randomized to receive placebo [see Clinical Studies (14)]. The adverse reactions most commonly leading to discontinuation (≥1% in the 8 mg or 12 mg Fycompa group and greater than placebo) were dizziness, somnolence, vertigo, aggression, anger, ataxia, blurred vision, irritability, and dysarthria [see Warnings and Precautions (5.1, 5.3)].
Most Common Adverse Reactions
Table 2 gives the incidence in the controlled clinical trials (Studies 1, 2, and 3) of the adverse reactions that occurred in ≥2% of patients with partial-onset seizures in the Fycompa 12 mg dose group and more frequent than placebo (in order of decreasing frequency for the 12 mg dose group).
The most common dose-related adverse reactions in patients receiving Fycompa at doses of 8 mg or 12 mg (≥4% and occurring at least 1% higher than the placebo group) included dizziness (36%), somnolence (16%), fatigue (10%), irritability (9%), falls (7%), nausea (7%), ataxia (5%), balance disorder (4%), gait disturbance (4%), vertigo (4%), and weight gain (4%). For almost every adverse reaction, rates were higher on 12 mg and more often led to dose reduction or discontinuation.

Pediatric Patients (4 to <12 years of age)
In two studies in pediatric patients 4 to <12 years of age with epilepsy, a total of 225 patients received Fycompa, with 110 patients exposed for at least 6 months, and 21 patients for at least 1 year. Adverse reactions in pediatric patients 4 to <12 years of age were similar to those seen in patients 12 years of age and older.
Primary Generalized Tonic-Clonic Seizures
A total of 81 patients receiving Fycompa 8 mg once daily constituted the safety population in the placebo-controlled trial in patients with primary generalized tonic-clonic seizures (Study 4). Approximately 57% of patients were female, and the mean age was 27 years.
In the controlled primary generalized tonic-clonic seizure clinical trial (Study 4), the adverse reaction profile was similar to that noted for the controlled partial-onset seizure clinical trials (Studies 1, 2, and 3).
Table 3 gives the incidence of adverse reactions in patients receiving Fycompa 8 mg (≥4% and higher than in the placebo group) in Study 4. The most common adverse reactions in patients receiving Fycompa (≥10% and greater than placebo) were dizziness (32%), fatigue (15%), headache (12%), somnolence (11%), and irritability (11%).
The adverse reactions most commonly leading to discontinuation in patients receiving Fycompa 8 mg (≥2% and greater than placebo) were vomiting (2%) and dizziness (2%).

Weight Gain
Weight gain has occurred with Fycompa.
In controlled partial-onset seizure clinical trials, Fycompa-treated adults gained an average of 1.1 kg (2.5 lbs) compared to an average of 0.3 kg (0.7 lbs) in placebo-treated adults with a median exposure of 19 weeks. The percentages of adults who gained at least 7% and 15% of their baseline body weight in Fycompa-treated patients were 9.1% and 0.9%, respectively, as compared to 4.5% and 0.2% of placebo-treated patients, respectively. Clinical monitoring of weight is recommended.
Similar increases in weight were also observed in adult and adolescent patients treated with Fycompa in the primary generalized tonic-clonic seizure clinical trial.
Elevated triglycerides
Increases in triglycerides have occurred with Fycompa use.
Comparison of Sex and Race
No significant sex differences were noted in the incidence of adverse reactions.
Although there were few non-Caucasian patients, no differences in the incidence of adverse reactions compared to Caucasian patients were observed.
6.2 Postmarketing ExperienceThe following adverse reactions have been identified during post approval use of Fycompa. 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.
Dermatologic: Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) [see Warnings and Precautions (5.5)]
Psychiatric: Acute psychosis, hallucinations, delusions, paranoia, delirium, confusional state, disorientation, memory impairment [see Warnings and Precautions (5.1)].
7 DRUG INTERACTIONS7.1 ContraceptivesWith concomitant use, Fycompa at a dose of 12 mg per day reduced levonorgestrel exposure by approximately 40% [see Clinical Pharmacology (12.3)]. Use of Fycompa with contraceptives containing levonorgestrel may render them less effective. Additional non-hormonal forms of contraception are recommended [see Use in Specific Populations (8.3)].
7.2 Moderate and Strong CYP3A4 InducersThe concomitant use of known moderate and strong CYP3A4 inducers including carbamazepine, phenytoin, or oxcarbazepine with Fycompa decreased the plasma levels of perampanel by approximately 50-67% [see Clinical Pharmacology (12.3)]. The starting doses for Fycompa should be increased in the presence of moderate or strong CYP3A4 inducers [see Dosage and Administration (2.3)].
When these moderate or strong CYP3A4 inducers are introduced or withdrawn from a patient’s treatment regimen, the patient should be closely monitored for clinical response and tolerability. Dose adjustment of Fycompa may be necessary [see Dosage and Administration (2.3)].
7.3 Alcohol and Other CNS DepressantsThe concomitant use of Fycompa and CNS depressants including alcohol may increase CNS depression. A pharmacodynamic interaction study in healthy subjects found that the effects of Fycompa on complex tasks such as driving ability were additive or supra-additive to the impairment effects of alcohol [see Clinical Pharmacology (12.3)]. Multiple dosing of Fycompa 12 mg per day also enhanced the effects of alcohol to interfere with vigilance and alertness, and increased levels of anger, confusion, and depression. These effects may also be seen when Fycompa is used in combination with other CNS depressants. Care should be taken when administering Fycompa with these agents. Patients should limit activity until they have experience with concomitant use of CNS depressants (e.g., benzodiazepines, narcotics, barbiturates, sedating antihistamines). Advise patients not to drive or operate machinery until they have gained sufficient experience on Fycompa to gauge whether it adversely affects these activities.
8 USE IN SPECIFIC POPULATIONS8.1 PregnancyPregnancy Exposure Registry
There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antiepileptic drugs (AEDs), such as Fycompa, during pregnancy. Encourage women who are taking Fycompa during pregnancy to enroll in the North American Antiepileptic Drug (NAAED) Pregnancy Registry by calling 1-888-233-2334 or visiting http://www.aedpregnancyregistry.org.
Risk Summary
There are no adequate data on the developmental risk associated with use in pregnant women. In animal studies, perampanel induced developmental toxicity in pregnant rat and rabbit at clinically relevant doses [see Data]. In the U.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 background risk of major birth defects and miscarriage for the indicated population is unknown.
Data
Animal Data
Oral administration of perampanel (1, 3, or 10 mg/kg/day) to pregnant rats throughout organogenesis resulted in an increase in visceral abnormalities (diverticulum of the intestine) at all doses tested; maternal toxicity was observed at the mid and high doses. In a dose-ranging study at higher oral doses (10, 30, or 60 mg/kg/day), embryo lethality and reduced fetal body weight were observed at the mid and high doses tested. The lowest dose tested (1 mg/kg/day) is similar to a human dose of 8 mg/day based on body surface area (mg/m2).
Upon oral administration of perampanel (1, 3, or 10 mg/kg/day) to pregnant rabbits throughout organogenesis, embryo lethality and maternal toxicity were observed at the mid and high doses tested; the no-effect dose for embryo-fetal developmental toxicity in rabbit (1 mg/kg/day) is approximately 2 times a human dose of 8 mg/day based on body surface area (mg/m2).
Oral administration of perampanel (1, 3, or 10 mg/kg/day) to rats throughout gestation and lactation resulted in fetal and pup deaths at the mid and high doses (associated with maternal toxicity) and delayed sexual maturation in males and females at the highest dose tested. No effects were observed on measures of neurobehavioral or reproductive function in the offspring. The no-effect dose for pre- and postnatal developmental toxicity in rat (1 mg/kg/day) is similar to a human dose of 8 mg/day based on body surface area (mg/m2).
8.2 LactationRisk Summary
There are no data on the presence of perampanel in human milk, the effects on the breastfed child, or the effects of the drug on milk production. Perampanel and/or its metabolites are present in rat milk, and are detected at concentrations higher than that in maternal plasma.
The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Fycompa and any potential adverse effects on the breastfed child from Fycompa or from the underlying maternal condition.
8.3 Females and Males of Reproductive PotentialContraception
Use of Fycompa may reduce the efficacy of hormonal contraceptives containing levonorgestrel. Advise women taking Fycompa who are using a levonorgestrel-containing contraceptive to use an additional non-hormonal form of contraception while using Fycompa and for a month after discontinuation [see Drug Interactions (7.1), Clinical Pharmacology (12.3)].
8.4 Pediatric UseSafety and effectiveness of Fycompa for the treatment of partial-onset seizures have been established in pediatric patients 4 years of age and older.
The safety and effectiveness of Fycompa in patients 12 years of age and older was established by three randomized double-blind, placebo-controlled, multicenter studies, which included 72 pediatric patients between 12 and 16 years of age exposed to Fycompa [see Clinical Pharmacology (12.3) and Clinical Studies (14.1)]. Use of Fycompa for the treatment of partial-onset seizures in pediatric patients 4 years to less than 12 years of age is supported by evidence from adequate and well-controlled studies of Fycompa in patients 12 years of age and older with partial onset seizures, pharmacokinetic data from adult and pediatric patients, and safety data in 225 pediatric patients 4 years to less than 12 years of age treated with Fycompa [see Adverse Reactions (6.1) and Clinical Pharmacology (12.3)].
The safety and efficacy of Fycompa for the adjunctive therapy of primary generalized tonic-clonic seizures in pediatric patients 12 years of age and older was established in a single randomized double-blind, placebo-controlled, multicenter trial (n=164), which included 11 pediatric patients 12 to 16 years of age exposed to Fycompa; an additional 6 patients were treated with Fycompa in the open-label extension of the study [see Clinical Studies (14.2)].
The safety and effectiveness of Fycompa for the treatment of partial-onset seizures in pediatric patients less than 4 years of age or for the treatment of primary generalized tonic-clonic seizures in pediatric patients less than 12 years of age have not been established.
Juvenile Animal Data
Oral administration of perampanel (1, 3, 3/10/30 mg/kg/day; high dose increased on postnatal days [PND] 28 and 56) to young rats for 12 weeks starting on PND 7 resulted in reduced body weight, reduced growth, neurobehavioral impairment (water maze performance and auditory startle habituation) at the mid and high doses, and delayed sexual maturation at the high doses. CNS signs (reduced activity, incoordination, excessive grooming/scratching), pup death, decreased hindlimb splay, and decreased hindlimb grip strength were observed at all doses. Effects on pup body weight, pup growth, hindlimb splay, impairment in the water maze performance, and auditory startle persisted after dosing was stopped. A no-effect dose for postnatal developmental toxicity was not identified in this study.
Oral administration of perampanel (1, 5, 5/10 mg/kg/day; high dose increased on PND 56) to juvenile dogs for 33 weeks, starting on PND 42, resulted in CNS signs (incoordination, excessive grooming/licking/scratching, spatial disorientation, and/or ataxic gait) at all doses tested.
8.5 Geriatric UseClinical studies of Fycompa did not include sufficient numbers of patients aged 65 and over to determine the safety and efficacy of Fycompa in the elderly population. Because of increased likelihood for adverse reactions in the elderly, dosing titration should proceed slowly in patients aged 65 years and older [see Dosage and Administration (2.5)].
8.6 Hepatic ImpairmentUse of Fycompa in patients with severe hepatic impairment is not recommended, and dosage adjustments are recommended in patients with mild or moderate hepatic impairment [see Dosage and Administration (2.4), Clinical Pharmacology (12.3)].
8.7 Renal ImpairmentDose adjustment is not required in patients with mild renal impairment. Fycompa should be used with caution in patients with moderate renal impairment, and slower titration may be considered. Use in patients with severe renal impairment or patients undergoing hemodialysis is not recommended [see Dosage and Administration (2.5), Clinical Pharmacology (12.3)].
9 DRUG ABUSE AND DEPENDENCE9.1 Controlled SubstanceFycompa contains perampanel and is listed as a Schedule III controlled substance.
9.2 AbusePrescription drug abuse is the intentional non-therapeutic use of a drug, even once, for its rewarding psychological or physiological effects. Drug addiction, which develops after repeated drug abuse, is characterized by a strong desire to take a drug despite harmful consequences, difficulty in controlling its use, giving a higher priority to drug use than to obligations, increased tolerance, and sometimes physical withdrawal. Drug abuse and drug addiction are separate and distinct from physical dependence (for example, abuse may not be accompanied by physical dependence) [see Drug Abuse and Dependence (9.3)].
Studies of human abuse potential were performed to evaluate the abuse potential of Fycompa (8 mg, 24 mg, and 36 mg) as compared to alprazolam C-IV (1.5 mg and 3 mg), and oral ketamine C-III (100 mg) in recreational polydrug users. Supra-therapeutic doses of Fycompa 24 and 36 mg produced responses for “Euphoria” that were similar to ketamine 100 mg and alprazolam 3 mg. For “High,” Fycompa 24 mg and 36 mg produced responses comparable to ketamine 100 mg and significantly higher than both doses of alprazolam on a visual analog scale (VAS). “Drug Liking,” “Overall Drug Liking,” and “Take Drug Again” for Fycompa were each statistically lower than ketamine 100 mg. In addition, for “Bad Drug Effects,” Fycompa 24 mg and 36 mg produced responses significantly higher than ketamine 100 mg.
For “Sedation,” Fycompa 24 and 36 mg produced responses similar to alprazolam 3 mg and higher than ketamine 100 mg.
Additionally, on VAS measures related to dissociative phenomena such as “Floating,” “Spaced Out,” and “Detached,” Fycompa at supra-therapeutic doses produced responses similar to ketamine 100 mg and greater than both doses of alprazolam tested. Of note, due to somnolence a number of subjects had missing data around Tmax of Fycompa. The above described data might represent an underestimate of Fycompa’s effects. The duration of effects of higher doses of Fycompa on the majority of measures was much greater than alprazolam 3 mg and ketamine 100 mg.
In this study, the incidence of euphoria following Fycompa administration 8 mg, 24 mg, and 36 mg was 37%, 46%, 46%, respectively, which was higher than alprazolam 3 mg (13%) but lower than ketamine 100 mg (89%).
9.3 DependencePhysical dependence is characterized by withdrawal symptoms after abrupt discontinuation or a significant dose reduction of a drug.
A nonclinical dependence study in rats demonstrated withdrawal symptoms, including hyperreactivity to handling, muscle rigidity, and decreases in food consumption and body weights.
Fycompa may cause dependence and withdrawal symptoms that may include anxiety, nervousness, irritability, fatigue, lethargy, asthenia, mood swings, and insomnia.
10 OVERDOSAGEThe highest reported overdose of Fycompa was 300 mg. Events reported after Fycompa overdose include somnolence, stupor, coma, psychiatric or behavioral reactions, altered mental status, and dizziness or gait disturbances.
There is no available specific antidote to the overdose reactions of Fycompa. In the event of overdose, standard medical practice for the management of any overdose should be used. An adequate airway, oxygenation, and ventilation should be ensured; monitoring of cardiac rhythm and vital sign measurement is recommended. A certified poison control center should be contacted for updated information on the management of overdose with Fycompa. Due to its long half-life, the reactions caused by Fycompa could be prolonged.
11 DESCRIPTIONFycompa tablets and oral suspension contain perampanel a non-competitive AMPA receptor antagonist as a 4:3 hydrate.
The chemical name of the active ingredient is 2-(1′,6′-dihydro-6′-oxo-1′-phenyl[2,3′-bipyridin]-5′-yl)-benzonitrile, hydrate (4:3).
The molecular formula is C23H15N3O • ¾H2O and the molecular weight is 362.90 (349.39 for anhydrous perampanel). It is a white to yellowish white powder. It is freely soluble in 1-methyl-2-pyrrolidinone, sparingly soluble in acetonitrile and acetone, slightly soluble in methanol, ethanol and ethyl acetate, very slightly soluble in 1-octanol and diethyl ether, and practically insoluble in heptane and water. The chemical structure is:
Tablets
Fycompa tablets are round, bi-convex, film-coated tablets containing 2 mg, 4 mg, 6 mg, 8 mg, 10 mg, or 12 mg of perampanel. Tablets contain the following inactive ingredients: lactose monohydrate, low substituted hydroxypropyl cellulose, povidone, microcrystalline cellulose, magnesium stearate, hypromellose, polyethylene glycol, talc, and titanium dioxide. Tablets of different strengths may contain yellow ferric oxide (10 mg and 2 mg), red ferric oxide (2 mg, 4 mg, 6 mg, 8 mg), black ferric oxide (8 mg), and FD&C Blue No. 2 (indigo carmine) aluminum lake (10 mg and 12 mg).
Oral Suspension
Fycompa oral suspension is a white to off-white opaque liquid providing perampanel in a concentration of 0.5 mg/mL. The oral suspension contains the following inactive ingredients: sorbitol, microcrystalline cellulose, carboxymethyl-cellulose sodium, poloxamer, simethicone, citric acid, sodium benzoate and purified water.
12 CLINICAL PHARMACOLOGY12.1 Mechanism of ActionPerampanel is a non-competitive antagonist of the ionotropic α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) glutamate receptor on post-synaptic neurons. Glutamate is the primary excitatory neurotransmitter in the central nervous system and is implicated in a number of neurological disorders caused by neuronal over excitation.
The precise mechanism by which Fycompa exerts its antiepileptic effects in humans is unknown.
12.2 PharmacodynamicsPsychomotor Performance
In a healthy volunteer study to assess the effects of Fycompa tablets on psychomotor performance using a standard battery of assessments including simulated driving, single and multiple daily doses of Fycompa 4 mg did not impair simple psychomotor tasks, driving performance, or sensorimotor coordination. Single and multiple doses of 8 mg and 12 mg impaired psychomotor performance in a dose-related manner. Car handling ability was impaired after dosing of Fycompa 12 mg, but postural stability was not significantly impaired. Performance testing returned to baseline within 2 weeks of cessation of Fycompa dosing.
Interactions with Alcohol
In the above study (see Psychomotor Performance), when administered to healthy subjects receiving alcohol to achieve a blood concentration of 80-100 mg/100 mL, Fycompa consistently impaired simple psychomotor performance after single doses of 4 to 12 mg, and after 21 days of multiple 12 mg/day doses. The effects of Fycompa on complex tasks such as driving ability were additive or supra-additive to the impairment effects of alcohol. Fycompa enhanced the effects of alcohol on vigilance and alertness, and increased levels of anger, confusion, and depression.
Potential to Prolong QT Interval
In a placebo-controlled thorough QT study of perampanel in healthy subjects, there was no evidence that perampanel caused QT interval prolongation of clinical significance at doses of 6 or 12 mg (i.e., the upper bound of the 95% confidence interval for the largest placebo-adjusted baseline-corrected QTc was below 10 msec). The exposures observed with the 12 mg dose in this study will not cover the exposures expected in patients with hepatic impairment taking doses over 6 mg/day. At the highest recommended dose (12 mg), perampanel did not prolong the QTc interval to any clinically relevant extent.
12.3 PharmacokineticsPharmacokinetics of perampanel are similar in healthy subjects, patients with partial-onset seizures, and patients with primary generalized tonic-clonic seizures. The half-life of perampanel is about 105 hours, so that steady state is reached in about 2-3 weeks. AUC of perampanel increased in a dose-proportional manner after single-dose administration of 0.2-12 mg tablets and after multiple-dose administration of 1-12 mg tablets once daily.
Fycompa oral suspension has comparable bioavailability to Fycompa tablets under steady state. Both formulations may be used interchangeably.
The pharmacokinetics of perampanel are similar when used as monotherapy or as adjunctive therapy for the treatment of partial-onset seizures (in the absence of concomitant moderate or strong CYP3A4 inducers).
Absorption
Perampanel is rapidly and completely absorbed after oral administration with negligible first-pass metabolism. Median time to reach peak concentration (tmax) ranged from 0.5 to 2.5 hours under fasted condition. Co-administration of Fycompa tablet with a high fat meal had no impact on the total exposure (AUC0-inf) of perampanel and reduced the peak plasma concentration (Cmax) of perampanel by 11%-40%. The tmax was delayed by approximately 1-3 hours in fed state compared to that under fasted conditions.
Distribution
Data from in vitro studies indicate that, in the concentration range of 20 to 2000 ng/mL, perampanel is approximately 95-96% bound to plasma proteins, mainly bound to albumin and α1-acid glycoprotein. Blood to plasma ratio of perampanel is 0.55-0.59.
Metabolism
Perampanel is extensively metabolized via primary oxidation and sequential glucuronidation. Oxidative metabolism is primarily mediated by CYP3A4/5 and to a lesser extent by CYP1A2 and CYP2B6, based on results of in vitro studies using recombinant human CYPs and human liver microsomes. Other CYP enzymes may also be involved.
Following administration of radiolabeled perampanel, unchanged perampanel accounted for 74-80% of total radioactivity in systemic circulation, whereas only trace amounts of individual perampanel metabolites were detected in plasma.
Elimination
Following administration of a radiolabeled perampanel tablet dose to 8 healthy elderly subjects, 22% of administered radioactivity was recovered in the urine and 48% in the feces. In urine and feces, recovered radioactivity was primarily composed of a mixture of oxidative and conjugated metabolites. Population pharmacokinetic analysis of pooled data from 19 Phase 1 studies reported that t1/2 of perampanel was 105 hours on average. Apparent clearance of perampanel in healthy subjects and patients was approximately 12 mL/min.
Specific Populations
Hepatic Impairment
The pharmacokinetics of perampanel following a single 1 mg tablet dose were evaluated in 12 subjects with mild and moderate hepatic impairment (Child-Pugh A and B, respectively) compared with 12 demographically matched healthy subjects. The total (free and protein bound) exposure (AUC0-inf) of perampanel was 50% greater in subjects with mild hepatic impairment and more than doubled (2.55-fold) in subjects with moderate hepatic impairment compared to their healthy controls. The AUC0-inf of free perampanel in subjects with mild and moderate hepatic impairment was 1.8-fold and 3.3-fold, respectively, of those in matched healthy controls. The t1/2 was prolonged in subjects with mild impairment (306 vs. 125 hours) and moderate impairment (295 vs. 139 hours). Perampanel has not been studied in subjects with severe hepatic impairment [see Dosage and Administration (2.4), Use in Specific Populations (8.6)].
Renal Impairment
A dedicated study has not been conducted to evaluate the pharmacokinetics of perampanel in patients with renal impairment. Population pharmacokinetic analysis was performed on pooled data from patients with partial-onset seizures and receiving Fycompa tablets up to 12 mg/day in placebo-controlled clinical trials. Results showed that perampanel apparent clearance was decreased by 27% in patients with mild renal impairment (creatinine clearance 50-80 mL/min) compared to patients with normal renal function (creatinine clearance >80 mL/min), with a corresponding 37% increase in AUC. Considering the substantial overlap in the exposure between normal and mildly impaired patients, no dosage adjustment is necessary for patients with mild renal impairment. Perampanel has not been studied in patients with severe renal impairment and patients undergoing hemodialysis [see Dosage and Administration (2.5), Use in Specific Populations (8.7)].
Sex
In a population pharmacokinetic analysis of patients with partial-onset and primary generalized tonic-clonic seizures receiving Fycompa tablets in placebo-controlled clinical trials, perampanel apparent clearance in females (0.54 L/hr) was 18% lower than in males (0.66 L/hr). No dosage adjustment is necessary based on sex.
Pediatrics
In a population pharmacokinetic analysis of healthy subjects and pediatric and adult patients with partial onset seizures, including 123 children 4 years to less than 12 years of age, 226 adolescents 12 years to less than 18 years of age, and 1912 adults 18 years of age and older, no significant effect of age or body weight on perampanel clearance was found.
Geriatrics
In a population pharmacokinetic analysis of patients with partial-onset seizures and primary generalized tonic-clonic seizures ranging in age from 12 to 74 years receiving Fycompa tablets in placebo-controlled trials, no significant effect of age on perampanel apparent clearance was found [see Dosage and Administration (2.6), Use in Specific Populations (8.5)].
Race
In a population pharmacokinetic analysis of patients with partial-onset seizures and primary generalized tonic-clonic seizures, which included 614 Caucasians, 15 Blacks, 4 Japanese, 4 American Indians/Alaska Natives, 79 Chinese and 108 other Asians receiving Fycompa tablets in placebo-controlled trials, no significant effect of race on perampanel apparent clearance was found. No dosage adjustment is necessary.
Drug Interaction Studies
In Vitro Assessment of Drug Interactions
Drug Metabolizing Enzymes
In human liver microsomes, perampanel at a concentration of 30 μmol/L, about 10 fold the steady state Cmax at a 12 mg dose, had a weak inhibitory effect on CYP2C8, CYP3A4, UGT1A9, and UGT2B7. Perampanel did not inhibit CYP1A2, CYP2A6, CYP2B6, CYP2C9, CYP2C19, CYP2D6, CYP2E1, UGT1A1, UGT1A4, and UGT1A6 up to a concentration of 30 µmol/L.
Compared with positive controls (including phenobarbital and rifampin), perampanel was found to weakly induce CYP2B6 (30 µmol/L) and CYP3A4/5 (≥3 µmol/L) in cultured human hepatocytes. Perampanel also induced UGT1A1 (≥3 µmol/L) and UGT1A4 (30 µmol/L). Perampanel did not induce CYP1A2 at concentrations up to 30 µmol/L.
Transporters
In vitro studies showed that perampanel is not a substrate or significant inhibitor of the following: organic anion transporting polypeptides 1B1 and 1B3; organic anion transporters 1, 2, 3, and 4; organic cation transporters 1, 2, and 3; efflux transporters P-glycoprotein and Breast Cancer Resistance Protein.
In Vivo Assessment of Drug Interactions
Drug Interactions with AEDs
Effect of Concomitant AEDs on Fycompa:
Carbamazepine. As an inducer of CYP enzymes, carbamazepine increases perampanel clearance. Steady state administration of carbamazepine at 300 mg BID in healthy subjects reduced the Cmax and AUC0-inf of a single 2 mg tablet dose of perampanel by 26% and 67%, respectively. The t1/2 of perampanel was shortened from 56.8 hours to 25 hours. In clinical studies examining partial-onset and primary generalized tonic-clonic seizures, a population pharmacokinetic analysis showed that perampanel AUC was reduced by 64% in patients on carbamazepine compared to the AUC in patients not on enzyme-inducing AEDs [see Dosage and Administration (2.3), Drug Interactions (7.2)].
Oxcarbazepine. In clinical studies examining partial-onset and primary generalized tonic-clonic seizures, a population pharmacokinetic analysis showed that perampanel AUC was reduced by 48% in patients on oxcarbazepine compared to patients not on enzyme-inducing AEDs [see Dosage and Administration (2.3), Drug Interactions (7.2)].
Eslicarbazepine. Eslicarbazepine is structurally similar to oxcarbazepine and thus may also reduce perampanel plasma concentrations when used concomitantly.
Phenytoin. In clinical studies examining partial-onset and primary generalized tonic-clonic seizures, a population pharmacokinetic analysis showed that perampanel AUC was reduced by 43% in patients on phenytoin compared to patients not on enzyme-inducing AEDs [see Dosage and Administration (2.3), Drug Interactions (7.2)].
Phenobarbital and Primidone: In a population pharmacokinetic analysis of patients with partial-onset and primary generalized tonic-clonic seizures in clinical trials (40 patients co-administered phenobarbital and 9 patients co-administered primidone), no significant effect on perampanel AUC was found. A modest effect of phenobarbital and primidone on perampanel concentrations cannot be excluded.
Topiramate: Population pharmacokinetic analysis of patients with partial-onset and primary generalized tonic-clonic seizures in clinical trials showed that perampanel AUC was reduced by approximately 19% in patients on topiramate compared to patients not on enzyme-inducing AEDs.
Other AEDs: Population pharmacokinetic analysis of patients with partial-onset and primary generalized tonic-clonic seizures in clinical trials showed that clobazam, clonazepam, lamotrigine, levetiracetam, valproate, and zonisamide did not have an effect on perampanel clearance.
Other strong CYP3A inducers (e.g., rifampin, St. John’s wort) may also greatly increase clearance of perampanel and reduce perampanel plasma concentrations [see Drug Interactions (7.2)].
Effect of Fycompa on Concomitant AEDs:
Fycompa tablets up to 12 mg/day did not significantly affect the clearance of clonazepam, levetiracetam, phenobarbital, phenytoin, topiramate, or zonisamide based on a population pharmacokinetic analysis of patients with partial-onset seizures in clinical trials. Fycompa had a statistically significant effect on the clearance of carbamazepine, clobazam, lamotrigine, and valproic acid, but the increases in clearance of these drugs were each less than 10% at the highest perampanel dose evaluated (12 mg/day). Fycompa co-administration resulted in a 26% decrease in oxcarbazepine clearance and increased its concentrations. The concentrations of 10-monohydroxy metabolite (MHD), the active metabolite of oxcarbazepine, were not measured.
Drug-drug Interaction Studies with Other Drugs
Effect of Other Drugs on Fycompa
Ketoconazole. Co-administration of single 1-mg dose of perampanel tablet with 400 mg once daily doses of ketoconazole, a strong CYP3A4 inhibitor, for 8 days in healthy subjects prolonged perampanel t1/2 by 15% (67.8 vs. 58.4 hours) and increased AUC0-inf by 20%.
Contraceptives. Perampanel Cmax and AUC0-72h were not altered when a single 6-mg dose of perampanel tablet was administered to healthy female subjects following a 21-day course of oral contraceptives containing ethinylestradiol 30 µg and levonorgestrel 150 µg.
Effect of Fycompa on Other Drugs
Midazolam. Perampanel administered as 6 mg tablet once daily doses for 20 days decreased AUC0-inf and Cmax of midazolam (a CYP3A4 substrate) by 13% and 15%, respectively, in healthy subjects.
Contraceptives. Co-administration of perampanel 4 mg tablet once daily with an oral contraceptive containing ethinylestradiol 30 µg and levonorgestrel 150 µg for 21 days did not alter Cmax or AUC0-24h of either ethinylestradiol or levonorgestrel in healthy female subjects. In another study, a single dose of the oral contraceptive was administered following 21-day once daily dosing of Fycompa 12 mg or 8 mg tablets in healthy females. Fycompa at 12 mg did not alter AUC0-24h of ethinylestradiol but decreased its Cmax by 18%, and also decreased Cmax and AUC0-24h of levonorgestrel by 42% and 40%, respectively. Fycompa at 8 mg did not have significant effect on Cmax or AUC0-24h of either ethinylestradiol or levonorgestrel, with a decrease in AUC0-24h of levonorgestrel (9% on average) [see Drug Interactions (7.1), Use in Specific Populations (8.3)].
Levodopa. Perampanel tablets administered as 4 mg once daily doses for 19 days had no effect on Cmax and AUC0-inf of levodopa in healthy subjects.
13 NONCLINICAL TOXICOLOGY13.1 Carcinogenesis, Mutagenesis, and Impairment of FertilityCarcinogenesis
Perampanel was administered orally to mice (1, 3, 10, or 30 mg/kg/day) and rats (10, 30, or 100 mg/kg/day in males; 3, 10, or 30 mg/kg/day in females) for up to 104 weeks. There was no evidence of drug-related tumors in either species. Plasma perampanel exposures (AUC) at the highest doses tested were less than that in humans dosed at 8 mg/day.
Mutagenesis
Perampanel was negative in the in vitro Ames and mouse lymphoma tk assays, and in the in vivo rat micronucleus assay.
Impairment of Fertility
In male and female rats administered perampanel (oral doses of 1, 10, or 30 mg/kg/day) prior to and throughout mating and continuing in females to gestation day 6, there were no clear effects on fertility. Prolonged and/or irregular estrus cycles were observed at all doses but particularly at the highest dose tested. Plasma perampanel exposures (AUC) at all doses were lower than that in humans dosed at 8 mg/day.
CLINICAL STUDIES14.1 Partial-Onset SeizuresThe efficacy of Fycompa in partial-onset seizures, with or without secondary generalization, was studied in patients who were not adequately controlled with 1 to 3 concomitant AEDs in 3 randomized, double-blind, placebo-controlled, multicenter trials (Studies 1, 2, and 3) in adult and pediatric patients (12 years of age and older). All trials had an initial 6-week Baseline Period, during which patients were required to have more than five seizures in order to be randomized. The Baseline Period was followed by a 19-week Treatment Period consisting of a 6-week Titration Phase and a 13-week Maintenance Phase. Patients in these 3 trials had a mean duration of epilepsy of approximately 21 years and a median baseline seizure frequency ranging from 9 to 14 seizures per 28 days. During the trials, more than 85% of patients were taking 2 to 3 concomitant AEDs with or without concurrent vagal nerve stimulation, and approximately 50% were on at least one AED known to induce CYP3A4, an enzyme critical to the metabolism of Fycompa (i.e., carbamazepine, oxcarbazepine, or phenytoin), resulting in a significant reduction in Fycompa’s serum concentration [see Drug Interactions (7.2), Clinical Pharmacology (12.3)].
Each study evaluated placebo and multiple Fycompa dosages (see Figure 1). During the Titration period in all 3 trials, patients on Fycompa received an initial 2 mg once daily dose, which was subsequently increased in weekly increments of 2 mg per day to the final dose. Patients experiencing intolerable adverse reactions were permitted to have their dose reduced to the previously tolerated dose.
The primary endpoint in Studies 1, 2, and 3 was the percent change in seizure frequency per 28 days during the Treatment Period as compared to the Baseline Period. The criterion for statistical significance was p<0.05. A statistically significant decrease in seizure rate was observed at doses of 4 to 12 mg per day. Dose response was apparent at 4 to 8 mg with little additional reduction in frequency at 12 mg per day.

Tables 4 and 5 present an analysis combining data from all 3 studies, grouping patients based upon whether or not concomitant enzyme-inducing AEDs (carbamazepine, oxcarbazepine, or phenytoin) were used. The analysis revealed a substantially reduced effect in the presence of inducers.

bThe proportion of patients with at least a 50% decrease in seizure frequency
Figure 2 shows the proportion of patients with different percent reductions during the maintenance phase over baseline across all three trials. Patients in whom the seizure frequency increased are shown at left as “worse.” Patients in whom the seizure frequency decreased are shown in the remaining four categories.
Figure 2. Proportion of Patients Exhibiting Different Percent Reductions During the Maintenance Phase Over Baseline Across All Three Trials.
The percentages of patients with a 50% or greater reduction in seizure frequency were 19%, 29%, 35%, 35% for placebo, 4, 8, and 12 mg, respectively.
14.2 Primary Generalized Tonic-Clonic (PGTC) SeizuresThe efficacy of Fycompa as adjunctive therapy in patients 12 years of age and older with idiopathic generalized epilepsy experiencing primary generalized tonic-clonic seizures was established in one multicenter, randomized, double-blind, placebo-controlled study (Study 4), conducted at 78 sites in 16 countries. Eligible patients on a stable dose of 1 to 3 AEDs experiencing at least 3 primary generalized tonic-clonic seizures during the 8-week baseline period were randomized to either Fycompa or placebo. Efficacy was analyzed in 162 patients (Fycompa N=81, placebo N=81) who received medication and at least one post-treatment seizure assessment. Patients were titrated over 4 weeks up to a dose of 8 mg per day or the highest tolerated dose and treated for an additional 13 weeks on the last dose level achieved at the end of the titration period. The total treatment period was 17 weeks. Study drug was given once per day.
The primary endpoint was the percent change from baseline in primary generalized tonic-clonic seizure frequency per 28 days during the treatment period as compared to the baseline period. The criterion for statistical significance was p<0.05. Table 6 shows the results of this study. A statistically significant decrease in seizure rate was observed with Fycompa compared to placebo.

Instructions for Use
Fycompa® (fī-COM-puh)
(perampanel)
Oral Suspension
Read this Instructions for Use before you start using Fycompa Oral Suspension and each time you get a refill. There may be new information. This leaflet does not take the place of talking to your healthcare provider about your medical condition or treatment.
Prepare the Fycompa Oral Suspension dose
You will need the following supplies: See Figure A
· Fycompa Oral Suspension bottle
· Bottle adapter
· Dosing syringe (1 dosing syringe is included in the Fycompa Oral Suspension box)
Figure A
Step 1. Remove the Fycompa Oral Suspension bottle, bottle adapter, and syringe from the box. See Figure A
Step 2. Shake the bottle well before each use. See Figure B
Step 3. Uncap the bottle and insert the bottle adapter into the bottle by pressing downward. See Figure C and Figure D
After the bottle adapter is in place, it cannot be removed.
Step 4. Check the dose in milliliters (mL) as prescribed by your healthcare provider. Find this number on the syringe. See Figure E
Step 5. Push the plunger of the syringe all the way down then insert the syringe into the upright bottle through the opening in the bottle adapter. See Figure F
Step 6. With the syringe in place, turn the bottle upside down. Pull the plunger to withdraw the dose prescribed by your healthcare provider (the amount of liquid medicine in Step 4). If you see air bubbles in the oral syringe, fully push in the plunger so that the oral solution flows back into the bottle. Then, withdraw your prescribed dose of oral suspension. See Figure G
Measure the mLs of medicine from the white layer at the end of the plunger, not the black layer.
Step 7. If the dose is more than 20 mL, you can use:
· 1 syringe, taking 2 steps to draw up the medicine in that same syringe
For example:
If your dose is 24 mL, draw up 20 mL in the syringe and squirt the medicine into your mouth, then draw up the remaining 4 mL in that same syringe.
If your dose is more than 20 mL, repeat Steps 4 through 6 when drawing up the remaining dose of medicine.
Step 8. Turn the bottle right-side up and remove the syringe from the bottle adapter. See Figure H
Step 9. Slowly squirt the Fycompa oral suspension directly into the corner of your mouth until all of the liquid medicine is given. If your dose is more than 20 mL, draw up 20 mL in the syringe and squirt the medicine into your mouth, then draw up the remaining amount in that same syringe. See Figure I
Step 10. Rinse the syringe with tap water after each use. See Figure J
· Fill a cup with water
· Pull back on the plunger and draw the water from the cup into the syringe
· Push down on the plunger to release the water into the sink
Step 11. Cap the bottle tightly. The cap will fit over the bottle adapter. See Figure K
