完整处方资料
1. 适应症和用途
VRAYLAR™是适用为:
● 精神分裂症的治疗[见临床研究(14.1)]
● 伴随I型双相障碍躁狂或混合发作的急性治疗[见临床研究(14.2)].
2. 剂量和给药方法
2.1 一般给药资料
VRAYLAR是口服给予1天1次和可有或无食物服用。
因为卡比米嗪及其活性代谢物的长半衰期,剂量变化将不完全反映在血浆共几周。开始VRAYLAR后和每次剂量变化后处方者应监视患者不良反应和治疗反应共几周[见警告和注意事项(5.5)和临床药理学(12.3)]。
最大推荐剂量是6 mg每天。在短期对照试验,每天6 mg以上剂量不提供增加有效性足以权衡剂量相关不良反应[见不良反应(6.1),临床研究(14)]。
2.2 精神分裂症
推荐剂量范围是1.5 mg至6 mg每天1次。VRAYLAR的开始剂量是1.5 mg。第2天剂量可被增加至3 mg。取决于临床反应和耐受性,可以1.5 mg或3 mg增量进一步剂量调整。
2.3 伴随I型双相障碍躁狂或混合发作
推荐剂量范围是3 mg至6 mg每天1次。VRAYLAR的开始剂量是1.5 mg和在第天应被增加至3 mg。取决于临床反应和耐受性,可以1.5 mg或3 mg增量进一步剂量调整。
2.4 对CYP3A4抑制剂和诱导剂剂量调整
CYP3A4是负责卡比米嗪的主要活性代谢物的形成和消除。
对患者开始一种强CYP3A4抑制剂当用稳定剂量VRAYLAR时的剂量推荐:如开始一种强CYP3A4抑制剂时,减低VRAYLAR的当前剂量一半。对服用4.5 mg每天患者,剂量应被减低至1.5 mg或3 mg每天。对服用1.5 mg每天患者,给药方案应被调整至每隔天。当CYP3A4抑制剂被撤去,可能需要增加VRAYLAR剂量[见药物相互作用(7.1)]。
剂量推荐对患者开始VRAYLAR治疗当早已用一种强CYP3A4抑制剂:患者在第1天和在第3天应被给予1.5 mg的VRAYLAR与在第2天无剂量给予。从第4天起,剂量应被给予1.5 mg每天,然后增加至最大剂量3 mg每天。当CYP3A4抑制剂被撤去,VRAYLAR剂量可能需增加[见药物相互作用(7.1)]。
对同时服用VRAYLAR与CYP3A4诱导剂患者:
未曾评价VRAYLAR和一种CYP3A4诱导剂的同时使用和不建议因为不清楚对活性药物和代谢物净效应[见剂量和给药方法(2.1),警告和注意事项(5.5),药物相互作用(7.1),临床药理学(12.3)]。
2.5 治疗终止
VRAYLAR的终止后,活性药物和代谢物的血浆浓度可能不立即下降反映在患者的临床症状;在~1周卡比米嗪及其活性代谢物的血浆浓度将下降50%[见临床药理学(12.3)]。没有系统地收集数据特别地对付患者从VRAYLAR转用其它抗精神病药物或有关同时给予其它抗精神药物。
3. 剂型和规格
可得到四种强度的VRAYLAR(卡比米嗪)胶囊。
● 1.5 mg胶囊:白色帽和体印有 “FL 1.5”

4. 禁忌证
对卡比米嗪超敏性反应病史患者中禁忌VRAYLAR。反应有范围从皮疹,瘙痒,荨麻疹,和事件提示血管水肿(如,舌肿胀,唇肿胀,面水肿,咽喉水肿,和肿胀面)。
5. 警告和注意事项
5.1 在有痴呆-相关精神病老年患者中增加死亡率
在有痴呆-相关精神病老年患者中抗精神病药物增加所有-原因死亡的风险。17例痴呆-相关精神病安慰剂-对照试验的分析(10周的模态持续时间和大多患者服用非典型性抗精神病药物) 揭示在药物-治疗患者死亡的风险为安慰剂-治疗患者的1.6至1.7倍间。跨越典型10-周对照试验过程,药物-治疗患者中死亡率约为4.5%,与之比较安慰剂-治疗患者率约2.6%。
但是死亡的原因是变异的,大多数死亡表现是性质或心血管(如,心衰,突然死亡)或感染(如,肺炎)。VRAYLAR没有被批准为有痴呆-相关精神病患者的治疗[见黑框警告,警告和注意事项]
5.2 在有痴呆-相关精神病老年患者心血管不良反应,包括卒中
在安慰剂-对照试验在有痴呆老年受试者,患者随机化至利培酮[risperidone],阿立哌唑[aripiprazole],和奥氮平[olanzapine]有一个卒中和短暂性脑缺血发作,包括致命性卒中的较高发生率。VRAYLAR没有被批准为有痴呆-相关精神病患者的治疗[见黑框警告,警告和注意事项(5.1)]。
5.3 抗精神病药物恶性症候群(NMS)
抗精神病药物恶性症候群(NMS),一个潜在的致命症状复合,曽被报道伴随给予抗精神病药物。NMS的临床表现是高热,肌强直,谵妄,和自律神经失调。另外征象可能包括肌酸磷酸激酶升高,肌红蛋白尿(横纹肌溶解症),和急性肾衰。
如怀疑NMS,立即终止VRAYLAR和提供强烈对症治疗和监视。
5.4 迟发性运动障碍
在用抗精神病药物治疗患者,包括VRAYLAR可能发生潜在地不可逆,不自觉的,运动障碍活动组成的迟发性运动障。老年,特别地老年妇女中风险似乎最高,但不可能预测那个患者是可能发生这个综合征。不知道是否不同抗精神病药品致迟发性运动障碍潜能不同。
。这个综合征可能发生在相对地简短治疗阶段后发生,甚至在低剂量。它也可能在治疗终止后发生。
对迟发性运动障碍没有已知的治疗,但是,如抗精神病治疗被终止,综合征可能部分地或完全地减免。但是,抗精神病治疗本身,可能抑制(或部分地抑制)综合征的体征和症状,可能掩盖基本过程。不知道对症性抑制对迟发性运动障碍长期过程的影响。
给予这些考虑,VRAYLAR应以最大可能减低迟发性运动障碍的风险方式被处方。慢性抗精神病治疗一般地应保留为患者:1) 患一种慢性疾病已知对抗精神病药物反应;和2) 不能或不适当得到另一种,有效,但潜在地较低危害的治疗。在患者的确需要慢性治疗,寻求使用最低剂量和最短的治疗的时间产生一个满意的临床反应。对继续治疗需要定期地再评估。
如患者用VRAYLAR出現迟发性运动障碍体征和症状,应考虑终止药物。但是,有些患者可能需要用VRAYLAR治疗尽管存在综合征。
5.5 晚发生不良反应
VRAYLAR治疗开始后几周可能首次出现不良事件,或许因为卡比米嗪及其主要代谢物的血浆水平随时间积蓄。作为结果,在短期试验不良反应的发生率可能不反映长期暴露后率[见剂量和给药方法(2.1),不良反应(6.1),临床药理学(12.3)]。
监视不良反应,包括EPS或静坐不能,和患者已开始VRAYLAR后几周和每次增加剂量后。考虑减低剂量或终止药物。
5.6 代谢变化
非典型性抗精神病药物,包括VRAYLAR,有致代谢变化,包括高血糖,糖尿病,血脂异常,和体重增量。但是迄今在这类中所有药物曽被显示产生有些代谢变化,各药有它自身特异性风险图形。
高血糖和糖尿病
用非典型抗精神病药物治疗患者中曽报道高血糖,在有些病例極度和伴隨酮症酸中毒或高渗性昏迷或死亡。抗精神病药物前或开后立即评估空腹血糖,和长期治疗期间定时监视。
精神分裂症
在有精神分裂症成年患者6-周,安慰剂-对照试验,空腹血糖从正常(<100 mg/dL)转移至高(≥126 mg/dL)和边缘(≥100和<126 mg/dL)至高患者比例用VRAYLAR和安慰剂治疗患者是相似。在长期,开放精神分裂症研究,有正常血红蛋白A1c基线值患者4%发生升高水平( ≥6.5%)。
双极性情感障碍
在有双极性情感疾病成年患者3-周,安慰剂-对照试验,空腹血糖从正常(<100 mg/dL)转移至高(≥126 mg/dL)和边缘(≥100和<126 mg/dL)转移至高患者的比例用VRAYLAR和安慰剂治疗患者中相似。在长期,开放躁郁症研究,有正常血红蛋白A1c基线值患者4%发生升高的水平(≥6.5%)。
血脂异常
非典型抗精神病药物致脂质不良变化。开始抗精神病药物前或后立即得到一个基线空腹脂质图形和治疗期间定期监视。
精神分裂症
在有精神分裂症成年患者6-周,安慰剂-对照试验,在用VRAYLAR和安慰剂治疗患者中有空腹总胆固醇,LDL,HDL和甘油三酯转移患者的比例相似。
双极性情感障碍
在有双极性情感障碍成年患者3-周,安慰剂-对照试验,在用VRAYLAR和安慰剂治疗患者中有空腹总胆固醇,LDL,HDL和甘油三酯转移患者的比例相似。
体重增量
非典型抗精神病药物,包括VRAYLAR的使用曽观察到体重增量. 在基线和其后频繁地监视体重。表1和2显示在6-周精神分裂症和3-周双相性情感障碍试验从基线至终点体重发生的变化。
在在精神分裂症长期,无对照试验用VRAYLAR,在12,24,和48周体重从基线均数变化分别为1.2 kg,1.7 kg,和2.5 kg。
5.7 白细胞减少,粒细胞减少,和粒细胞缺乏症
用抗精神病药物,包括VRAYLAR治疗期间曾报道白细胞减少和粒细胞减少。用在这类其它药物曾报道粒细胞缺乏症(包括致死性病例)。
对白细胞减少和粒细胞减少包括预先存在低白细胞计数(WBC)或粒细胞绝对计数(ANC)和药物诱导白细胞减少或粒细胞减少病史风险因子可能性。在有预先存在低WBC或ANC或药物诱导白细胞减少或粒细胞减少病史患者,治疗的头几个月期间频繁地进行一个完全学细胞计数(CBC)。在这类患者中,在缺乏其它致病因子中WBC临床显著下降的首次征象时考虑终止VRAYLAR。
监视有临床显著粒细胞减少患者发热或感染的其它症状或体征和及时治疗如这类症状或体征发生。在有粒细胞绝对计数< 1000/mm3患者终止VRAYLAR和跟踪他们的WBC直至恢复。.
5.8 体位性低血压和晕厥
非典型抗精神病药物致体位性低血压和晕厥。一般说来,初始剂量滴定调整期间和当增加剂量时风险最大。VRAYLAR试验中症状性体位性低血压不频繁和VRAYLAR不比安慰剂更频繁。未观察到晕厥。
容易低血压患者(如,老年患者,有脱水患者,低血容量,和同时用抗高血压药物治疗),有移植心血管病患者(心肌梗死。缺血性心脏病,心衰,或传导异常),和有脑心血管病患者应被监视体位性低血压生命征象。未曾在心肌梗死或不稳定心血管病最近病史患者中评价VRAYLAR。在上市前临床试验排除这类患者。
5.9 癫痫发作
像其它抗精神病药物,VRAYLAR可能致癫痫发作。有癫痫发作病史或有较低癫痫阈值情况患者风险最大。在老年患者中癫痫阈值较低情况可能更普遍。
5.10 对认知和运动受损潜能
VRAYLAR,像其它抗精神病药物,有损害判断力,思维或运动技能的潜能。
在6-周精神分裂症试验,VRAYLAR-治疗患者报道嗜睡7%(睡眠过多,镇静,和嗜睡)与之比较安慰剂-治疗患者6%。在3-周双相性情感障碍试验,VRAYLAR-治疗患者报道嗜睡8%与之比较安慰剂-治疗患者4%。
患者应被告诫关于操作危险性机械,包括汽车,直至他们合理地确认用VRAYLAR治疗没有不良地影响他们。
5.11 体温失调
非典型抗精神病药物可能破坏身体减低核心体温的能力。剧烈运动,暴露至极热,脱水,和抗胆碱能药物可能对升高核心体温有贡献;经历这些情况患者谨慎使用VRAYLAR。
5.12 吞咽困难
伴随抗精神病药物使用食管运动功能障碍和吸入。用VRAYLAR曾报道吞咽困难。处于对吸入风险患者应慎用VRAYLAR和其它抗精神病药物。

6.1 临床研究经验
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。
下面资料衍生自对VRAYLAR临床试验数据库,consisting of 1733例有精神分裂症患者(年龄18至65)和1025例有躁狂或混合发作伴随I型双相障碍患者(年龄18至65)宝路至一或更多剂有总体经历566.5患者-年。这些患者中,1317例参加安慰剂-对照,6-周精神分裂症试验用剂量范围从1.5 mg至12 mg/day和623例参加安慰剂-对照,3-周双相性情感障碍试验用剂量范围从3 mg至12 mg/day。总共364例VRAYLAR-治疗患者有至少24周暴露和239例VRAYLAR-治疗患者有至少48周暴露。
有精神分裂症患者
以下发现是根据四项安慰剂-对照,6-周精神分裂症试验用VRAYLAR剂量范围从1.5至12 mg 每天1次。
不良反应伴随终止治疗:在VRAYLAR-治疗患者没有单个不良反应导致终止发生率≥ 2%和至少安慰剂率两倍。
常见不良反应(≥ 5%和安慰剂率至少两倍):锥体外系症状和静坐不能。
表3中显示任何剂量不良反应有一个发生率 ≥ 2%和大于安慰剂。
有双极性情感障碍
以下发现是根据三项安慰剂-对照,3-周双相性情感障碍试验用VRAYLAR剂量范围从3至12 mg每天1次。
不良反应伴随终止治疗:唯有不良反应导致终止在VRAYLAR-治疗患者发生率≥ 2%和至少安慰剂率两倍是静坐不能(2%)。总体而言,在这些试验接受VRAYLAR患者12%由于一种不良反应终止治疗,与之比较安慰剂-治疗患者有7%。
常见不良反应(≥ 5%和安慰剂率至少两倍):锥体外系症状,静坐不能,消化不良,呕吐,嗜睡,和躁动。
表4中显示在任何剂量有一个发生率≥ 2%和大于安慰剂的不良反应。
肌张力障碍
肌张力障碍的症状,延长肌肉群异常收缩,治疗的头几天期间可能发生在怀疑个体。肌张力障碍症状包括:颈肌肉痉挛,有时进展至喉头紧闭,吞咽困难,呼吸困难,和/或舌的突出。但是这些症状可能发生在低剂量,它们发生更频繁和有更大严重程度有高效力和第一代抗精神病药物的较高剂量。观察到在男性和较年轻年龄组急性肌张力障碍风险升高。
锥体外系症状(EPS)和静坐不能
在精神分裂症和双相性情感障碍试验,利用Simpson Angus量表(SAS)对治疗-出现EPS(帕金森病)(在基线时SAS总评分≤ 3和基线后> 3 )和Barnes静坐不能量表(BARS)对治疗-出现静坐不能(在基线时BARS总评分 ≤ 2和基线后> 2)客观地收集数据。
在6-周精神分裂症试验,报道与锥体外系症状(EPS)相关事件的发生率,对VRAYLAR-治疗患者除外静坐不能和躁动为17%相比对安慰剂-治疗患者8%。这些事件导致VRAYLAR-治疗患者终止0.3%相比安慰剂-治疗患者0.2%。静坐不能的发生率对VRAYLAR-治疗患者为11% 相比对安慰剂-治疗患者4%。这些事件导致VRAYLAR-治疗患者终止0.5%相比安慰剂-治疗患者为0.2%。表5显示EPS的发生率。
在3-周双相性情感障碍试验,报道与锥体外系症状(EPS)相关事件的发生率,除外静坐不能和躁动,对VRAYLAR-治疗患者为28%相比对安慰剂-治疗患者12%。这些事件导致在VRAYLAR-治疗患者1%终止相比安慰剂-治疗患者为0.2%。对VRAYLAR-治疗患者静坐不能发生率为20%相比对安慰剂-治疗患者为5%。这些事件导致VRAYLAR-治疗患者2%终止相比安慰剂-治疗患者为0%。表6提供EPS的发生率。
白内障
在长期无对照精神分裂症(48-周)和双极性情感障碍(16-周)试验,白内障的发生率分别为0.1%和0.2%。在非临床研究中观察到白内障的发生[见非临床毒理学(13.2)]。在这个时候不能除外透镜变化或白内障的可能性。
生命体征变化
VRAYLAR-治疗患者和安慰剂-治疗患者间至终点卧位血压参数在均数从基线变化没有临床意义差别除了VRAYLAR-治疗精神分裂症患者在 9 -12 mg/day仰卧舒张压增加。
表7和8显示来自6-周精神分裂症和3-周双相性情感障碍试验合并数据。
实验室测试中变化
在6-周精神分裂症试验,有转氨酶升高正常参比范围上限≥3倍患者的比例对VRAYLAR-治疗患者范围1%和2%间,随剂量增加,和对安慰剂-治疗患者为1%。在3-周双相性情感障碍试验,有转氨酶升高正常参比范围≥3倍患者的比例,对VRAYLAR-治疗患者范围2%和4%间取决于给予的剂量组和对安慰剂-治疗患者为2%。
6周精神分裂症试验对VRAYLAR-治疗患者范围4%和6%间,随剂量增加,和对安慰剂-治疗患者为4%。在3-周双相性情感障碍试验有CPK升高大于1000 U/L患者的比例在卡比米嗪和安慰剂-治疗患者是约4%。
VRAYLAR的上市前评价期间观察到的其他不良反应
下面列出2758例VRAYLAR-治疗患者的数据库内用VRAYLAR治疗患者在剂量≥ 1.5 mg 1天1次报告的不良反应。被列出反应是那些可能是有临床重要性,以及反应是对药理学或其他根据合理药物相关。在 VRAYLAR说明书其他处未被包括出现的反应。
反应被进一步按器官类别和按照频度降序列出,按照以下定义:那些发生至少1/100患者(频繁)[在这个列表只有来自安慰剂-对照研究表结果没有列出]; 那些发生1/100至1/1000患者(不经常);和那些发生少于1/1000患者(罕见)。

7. 药物相互作用
7.1 与VRAYLAR有临床上重要相互作用药物
7.2 与VRAYLAR无临床上重要相互作用药物
根据体外研究,VRAYLAR与CYP1A2,CYP2A6,CYP2C9,CYP2C19,CYP2D6,CYP2E,和CYP3A4,或OATP1B1,OATP1B3,BCRP,OCT2,OAT1和OAT3的底物可能不知临床重要药代动力学药物相互作用[见临床药理学(12.3)].
8. 特殊人群中使用
8.1 妊娠
妊娠暴露注册
有一个妊娠暴露注册监视妇女妊娠期间暴露至VRAYLAR妊娠结局。为更多资料,联系美国国家对非典型抗精神病药物妊娠注册电话1-866-961-2388或访问http://womensmentalhealth.org/clinical-and-researchprograms/妊娠registry/.
风险总结
在妊娠的第三个三个月期间被暴露至抗精神病药物的新生儿是处于分娩后椎体外系和/或戒断症状。在妊娠妇女中使用VRAYLAR没有可得到的数据告知对出生缺陷或流产任何药物-相关风险。根据动物数据VRAYLAR可能致胎儿危害。大鼠器官形成期时给予卡比米嗪在药物暴露低于在最大推荐人剂量(MRHD)6 mg/day人暴露致畸形,下肢幼畜生存,和发育延迟。但是,在兔中在剂量至MRHD 6 mg/day的4.6倍卡比米嗪没有致畸性[见数据]。不知道对适用人群中主要出生缺陷和流产的估计背景风险。在美国一般人群,主要出生缺陷和在临床上公认妊娠的估计背景风险分别是2-4%和15-20%。忠告妊娠妇女对胎儿潜在风险。
临床考虑
胎儿/新生儿不良反应
新生儿母亲在妊娠第三个三个月期间暴露于抗精神病药物曽报道锥体外系和/或戒断症状,包括激动,张力亢进,肌张力低下,震颤,嗜睡,呼吸窘迫和喂养障碍。这些症状严重程度变化。有些新生儿在几小时内或几天内每天特异性治疗恢复;其他需要延长住院。监视新生儿锥体外系和/或戒断症状和适当地处理症状。
数据
动物数据
妊娠大鼠在器官形成期时给予卡比米嗪在口服剂量0.5,2.5,和7.5 mg/kg/day根据总卡比米嗪的AUC(即卡比米嗪,DCAR,和DDCAR之和)它是最大推荐人剂量(MRHD)6 mg/day的0.2至3.5倍致胎儿发育毒性在所有剂量包括减低体重,减低雄性肛门与生殖器距离和弯曲肢骨,肩胛骨和肱骨的畸形。这些效应发生在缺乏或存在母体毒性。母体毒性,观察到作为体重和食物耗量减低,发生在根据总卡比米嗪的AUC剂量MRHD 6 mg/kg/day的1.2和3.5-倍。在这些剂量,卡比米嗪致胎儿畸形(局部化胎儿胸胎儿胸水舯),内脏变异(未发育/不发达肾乳头和/或尿道扩张),和骨骼发育变异(弯曲的肋骨,未骨化胸骨)。卡比米嗪对胎儿生存无影响。
妊娠大鼠妊娠和哺乳期间给予卡比米嗪在口服剂量of 0.1,0.3,和1 mg/kg/day根据总卡比米嗪AUC是MRHD 6 mg/day的0.03至0.4倍根据总卡比米嗪AUC嗪在剂量MRHD 6 mg/day的0.4倍在缺乏母体毒性致第一代幼畜产后生存率,出生体重,和断奶后体重减低。第一代幼畜还有苍白,冷体和发育延迟(肾乳头不发生或欠发育和在雄性这降低听觉惊吓反应)。第一代幼畜生殖性能未受影响;但是,第二代幼畜有临床征象和较低体重相似于这些第一代幼畜。
妊娠兔在器官形成期时给予卡比米嗪在口服剂量0.1,1,和5 mg/kg/day,根据总卡比米嗪AUC是MRHD 6 mg/day的0.02至4.6倍不是致畸胎性。根据总卡比米嗪AUC,MRHD 6 mg/day母畜体重和食耗量减低减低4.6 倍; 但是,未观察到对妊娠参数或生殖器官不良影响。
8.2 哺乳
风险总结
未曾进行哺乳研究评估在人乳汁中卡比米嗪的存在,对哺乳喂养婴儿的影响,或对乳汁生产的影响。在大鼠乳汁中存在卡比米嗪。哺乳喂养的发育和健康益处应与母亲对VRAYLAR临床需求和来自VRAYLAR或来自母体所有情况对哺乳喂养婴儿任何潜在不良影响一并考虑。
8.4 儿童使用
未曾确定在儿童患者安全性和有效性。未曾进行VRAYLAR的儿童研究。妊娠的第三个三个月时暴露至抗精神病药物,分娩后新生儿是处在对锥体外系和/或戒断症状风险[见特殊人群中使用(8.1)]。
8.5 老年人使用
在VRAYLAR精神分裂症和双极性情感障碍治疗临床试验没有包括足够的年龄65和以上患者数以确定他们的反应是否与较年轻患者不同。一般说来,对一位老年患者剂量选择应谨慎,通常在给药范围低端开始,反映减低肝,肾,或心功能,和同时疾病或其它药物治疗更高频数。
老年有痴呆-相关精神病患者用VRAYLAR治疗与安慰剂比较是处在死亡风险增加。VRAYLAR没有被批准为有痴呆-相关精神病患者的治疗[见黑框警告和警告和注意事项(5.1,5.2)]。
8.6 肝受损
在有轻度至中度肝受损患者(Child-Pugh评分5和9间)无需对VRAYLAR剂量调整[见临床药理学12.3)]。建议有严重肝受损患者(Child-Pugh评分10和15间)不使用VRAYLAR。在这个患者群中VRAYLAR未曾被评价。
8.7 肾受损
有轻度至中度(CrCL ≥ 30 mL/minute) 肾受损患者无需对VRAYLAR剂量调整[见临床药理学12.3)]。
建议有严重肾受损(CrCL < 30 mL/minute)患者不使用VRAYLAR。未曾在这个患者群评价VRAYLAR。
8.8 吸烟
对吸烟患者无需对VRAYLAR剂量调整。 VRAYLAR不是对CYP1A2底物,预计吸烟对VRAYLAR的药代动力学没有影响。
8.9 其它特殊人群
无需根据患者的年龄,性别,或种族调整剂量。这些因子不影响VRAYLAR的药代动力学[见临床药理学12.3)]。
9. 药物滥用和依赖性
9.1 受控制物质
VRAYLAR不是受控制物质。
9.2 滥用
未曾在动物或人类对VRAYLAR的滥用潜能或诱发耐受性能力系统地研究。
9.3 依赖性
未曾在动物或人类对VRAYLAR的身体依赖性潜能系统地研究。
10. 药物过量
10.1 人类经验
在上市前临床试验涉及VRAYLAR在约5000例患者或健康受试者,被报道一例患者意外急性药物过量(48 mg/day)。这例患者经历姿势性昏厥和镇静。在相同天患者完全恢复。
10.2 药物过量的处理
对VRAYLAR没有已知的特异性抗毒药。在处理过量中,提供支持性疗法,包括严密医学监督和监视,和考虑多种药物涉及。在过量情况中,咨询合格的美国毒物控制中心(1-800-222-1222)为更新指导原则和咨询建议。
11. 一般描述
VRAYLAR的活性成分是盐酸卡比米嗪[cariprazine HCl],一种非典型抗精神病药物。化学名为trans-N-{4-[2-[4-(2,3-dichlorophenyl)piperazine-1-yl]ethyl]cyclohexyl}-N’,N’-dimethylurea hydrochloride;其经验式为C21H33Cl3N4O和其分子量为463.9 g/mol。化学结构式为:
VRAYLAR胶囊是只意向口服给药。每个硬明胶胶囊含一种白色至淡白色盐酸卡比米嗪粉,它等同于1.5,3,4.5,或6 mg of 卡比米嗪碱。此外,胶囊包括以下无活性成分:明胶,硬脂酸镁,预明胶化淀粉,虫胶,和二氧化钛。Colorants包括black iron oxide(1.5,3,和6 mg),FD&C Blue 1(3,4.5,和6 mg),FD&C Red 3(6 mg),FD&C Red 40(3和4.5 mg),或yellow iron oxide(3和4.5 mg).
12. 临床药理学
12.1 作用机制
不知道卡比米嗪在精神分裂症和I型双相障碍的作用机制。但是,卡比米嗪的疗效可能被通过一个部分激动剂活性在中枢多巴胺D2和五羟色胺5-HT1A受体和在五羟色胺5-HT2A受体拮抗剂活性的组合介导。卡比米嗪形成两个主要代谢物,去甲基卡比米嗪(DCAR)和二去甲基卡比米嗪(DDCAR),在体外有受体结合图形与母体药物受体结合图形相似。
12.2 药效动力学
卡比米嗪作用在多巴胺D3和D2受体如同一个部分激动剂有高结合亲和力(Ki值分别0.085 nM,和0.49 nM(D2L)和0.69 nM(D2S))和在五羟色胺5-HT1A受体(Ki值2.6 nM)。卡比米嗪在5-HT2B和5-HT2A受体作用如同一个拮抗剂有高和中度结合亲和力(Ki值分别0.58 nM和18.8 nM)以及它结合至组胺H1受体(Ki值23.2 nM)。卡比米嗪对五羟色胺5HT2C和α1A-肾上腺素能受体(Ki值分别134 nM和155 nM)显示较低结合亲和力和对胆碱能毒蕈碱受体亲和力没有明显亲和力(IC50>1000 nM)。
对QTc间期影响
在剂量三倍最大推荐剂量,卡比米嗪不延长QTc间期至临床相关程度。
12.3 药代动力学
VRAYLAR活性被认为是通过卡比米嗪和其两个主要活性代谢物介导的,去甲基卡比米嗪(DCAR)和二去甲基卡比米嗪(DDCAR),其是药理学上等同于卡比米嗪.
多剂量给予VRAYLAR后,均数卡比米嗪和DCAR浓度在周1至周2左右时达到稳态和均数DDCAR浓度似乎是在周4至周8左右接近稳态在一项12-周研究(图1)。根据到达稳态时间半衰期,从均数浓度-时间曲线估计,对卡比米嗪是 2至4 天,而对DDCAR约1至3周。跨越患者对主要活性代谢物DDCAR达到稳态时间是变异的,有些患者在12周治疗结束时没有实现稳态[见剂量和给药方法(2.1),警告和注意事项(5.5)]。12-周治疗结束时DCAR和DDCAR的均数浓度分别约是卡比米嗪浓度的30%和400%。
VRAYLAR的终止后,卡比米嗪,DCAR,和DDCAR血浆浓度以多指数方式下降。末次剂量后1周DDCAR的均数血浆浓度减低约50%,和在大约1天均数卡比米嗪和DCAR浓度下降 50%。对卡比米嗪和DCAR在1周内血浆暴露下降约90%,和对DDCAR在约4周。单次剂量1 mg的卡比米嗪给药后,给药8周仍可检测到DDCAR。
跨越治疗剂量范围VRAYLAR的多次给药后,卡比米嗪,DCAR,和DDCAR的血浆暴露,接近正比例增加。

单次剂量VRAYLAR给药后,血浆卡比米嗪峰浓度发生在约3-6小时。
单剂量1.5 mg VRAYLAR胶囊与一个高-脂肪餐给药不显著影响卡比米嗪或DCAR的Cmax和AUC。
分布
卡比米嗪及其主要 活性代谢物是高度地结合(91至97%)至血浆蛋白。
消除
代谢
卡比米嗪被CYP3A4广泛地代谢和,被CYP2D6至较低程度至DCAR和DDCAR。DCAR被被CYP3A4和CYP2D6进一步代谢至DDCAR。然后被CYP3A4DDCAR代谢至一个羟基化代谢物。
排泄
有精神分裂症患者给予12.5 mg/day卡比米嗪共27天后,在尿中发现约21%的每天剂量,有约1.2%的每天剂量在尿中以未变化的卡比米嗪被排泄。
在特殊人群中研究
肝受损
与健康受试者比较,单次剂量1 mg卡比米嗪或0.5 mg 卡比米嗪共14天后有或轻度或中度肝受损患者(Child-Pugh评分5和9间)对卡比米嗪有约25%较高暴露(Cmax和AUC)和对主要活性代谢物,DCAR和DDCAR约45%较低暴露[见特殊人群中使用(8.6)]。
肾受损
卡比米嗪及其主要活性代谢物在尿中很少排泄。药代动力学分析表明血浆清除率和肌酐清除率间无显著相互关系[见特殊人群中使用(8.7)]。
CYP2D6弱代谢者
CYP2D6弱代谢状态对卡比米嗪,DCAR,或DDCAR的药代动力学没有临床相关影响。
年龄,性别,种族
年龄,性别,或种族对卡比米嗪,DCAR,或DDCAR的药代动力学没有临床相关影响。
药物相互作用研究
体外研究
在体外卡比米嗪及其主要活性代谢物不诱导CYP1A2和CYP3A4酶和是CYP1A2,CYP2C9,CYP2D6,和CYP3A4的弱抑制剂。在体外卡比米嗪也是CYP2C19,CYP2A6,和CYP2E1的弱抑制剂。
卡比米嗪及其主要活性代谢物不是P-糖蛋白(P-gp),有机阴离子转运多肽1B1和1B3(OATP1B1和OATP1B3),和乳癌耐药蛋白(BCRP)的底物。
在体外卡比米嗪及其主要活性代谢物是转运蛋白OATP1B1,OATP1B3,BCRP,有机阳离子转运蛋白2(OCT2),和有机阴离子转运蛋白1和3(OAT1和OAT3)差或非-抑制剂。主要活性代谢物也是转运蛋白P-g差或非-抑制剂虽然根据在体外在高剂量理论上GI浓度卡比米嗪或许是一个P-gp抑制剂。
CYP3A4抑制剂
酮康唑(400 mg/day),一种强CYP3A4抑制剂,与VRAYLAR(0.5 mg/day)的共同给药分别增加卡比米嗪Cmax和AUC0-24h约3.5-倍和4-倍;增加DDCAR Cmax和AUC0-24h约1.5-倍;和减低DCAR Cmax和AUC0-24h约三分之一。未研究中度CYP3A4抑制剂的影响。
CYP3A4诱导剂
CYP3A4是负责卡比米嗪活性代谢物的形成和消除。未曾评价CYP3A4诱导剂对卡比米嗪及其主要活性代谢物血浆暴露的影响,和净影响不清楚。
CYP2D6抑制剂
根据在CYP2D6弱代谢者中的观察预计CYP2D6抑制剂不影响卡比米嗪,DCAR或DDCAR的 药代动力学。

Vraylar
Generic Name: cariprazine
Dosage Form: capsule, gelatin coated
. Last updated on May 1, 2019.
WARNING: INCREASED MORTALITY IN ELDERLY PATIENTS WITH DEMENTIA-RELATED PSYCHOSIS; and SUICIDAL THOUGHTS AND BEHAVIORS
Increased Mortality in Elderly Patients with Dementia-Related Psychosis
Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Vraylar is not approved for the treatment of patients with dementia-related psychosis [see Warnings and Precautions (5.1)].
Suicidal Thoughts and Behaviors
Antidepressants increased the risk of suicidal thoughts and behaviors in pediatric and young adult patients in short-term studies. Closely monitor all antidepressant-treated patients for clinical worsening, and for the emergence of suicidal thoughts and behaviors [see Warnings and Precautions (5.2)]. The safety and effectiveness of Vraylar have not been established in pediatric patients [see Use in Specific Populations (8.4)].
1. INDICATIONS AND USAGE
Vraylar® is indicated for the:
• Treatment of schizophrenia in adults [see Clinical Studies (14.1)]
• Acute treatment of manic or mixed episodes associated with bipolar I disorder in adults [see Clinical Studies (14.2)]
• Treatment of depressive episodes associated with bipolar I disorder (bipolar depression) in adults [see Clinical Studies (14.3)]
2. DOSAGE AND ADMINISTRATION2.1 General Dosing InformationVraylar is given orally once daily and can be taken with or without food.
Because of the long half-life of cariprazine and its active metabolites, changes in dose will not be fully reflected in plasma for several weeks. Prescribers should monitor patients for adverse reactions and treatment response for several weeks after starting Vraylar and after each dosage change [see Warnings and Precautions (5.6), Clinical Pharmacology (12.3)].
2.2 SchizophreniaThe recommended dosage range is 1.5 mg to 6 mg once daily. The starting dosage of Vraylar is 1.5 mg daily. The dosage can be increased to 3 mg on Day 2. Depending upon clinical response and tolerability, further dose adjustments can be made in 1.5 mg or 3 mg increments. The maximum recommended dosage is 6 mg daily. In short-term controlled trials, dosages above 6 mg daily do not confer increased effectiveness sufficient to outweigh dose-related adverse reactions [see Adverse Reactions (6.1), Clinical Studies (14.1)].
2.3 Manic or Mixed Episodes Associated with Bipolar I DisorderThe recommended dosage range is 3 mg to 6 mg once daily. The starting dose of Vraylar is 1.5 mg and should be increased to 3 mg on Day 2. Depending upon clinical response and tolerability, further dose adjustments can be made in 1.5 mg or 3 mg increments. The maximum recommended dosage is 6 mg daily. In short-term controlled trials, dosages above 6 mg daily do not confer increased effectiveness sufficient to outweigh dose-related adverse reactions [see Adverse Reactions (6.1), Clinical Studies (14.2)].
2.4 Depressive Episodes Associated with Bipolar I Disorder (Bipolar Depression)The starting dose of Vraylar is 1.5 mg once daily. Depending upon clinical response and tolerability, the dosage can be increased to 3 mg once daily on Day 15. Maximum recommended dosage is 3 mg once daily.
2.5 Dosage Adjustments for CYP3A4 Inhibitors and InducersCYP3A4 is responsible for the formation and elimination of the major active metabolites of cariprazine.
Dosage recommendation for patients initiating a strong CYP3A4 inhibitor while on a stable dose of Vraylar: If a strong CYP3A4 inhibitor is initiated, reduce the current dosage of Vraylar by half. For patients taking 4.5 mg daily, the dosage should be reduced to 1.5 mg or 3 mg daily. For patients taking 1.5 mg daily, the dosing regimen should be adjusted to every other day. When the CYP3A4 inhibitor is withdrawn, Vraylar dosage may need to be increased [see Drug Interactions (7.1)].
Dosage recommendation for patients initiating Vraylar therapy while already on a strong CYP3A4 inhibitor: Patients should be administered 1.5 mg of Vraylar on Day 1 and on Day 3 with no dose administered on Day 2. From Day 4 onward, the dose should be administered at 1.5 mg daily, then increased to a maximum dose of 3 mg daily. When the CYP3A4 inhibitor is withdrawn, Vraylar dosage may need to be increased [see Drug Interactions (7.1)].
Dosage recommendation for patients concomitantly taking Vraylar with CYP3A4 inducers:
Concomitant use of Vraylar and a CYP3A4 inducer has not been evaluated and is not recommended because the net effect on active drug and metabolites is unclear [see Dosage and Administration (2.1), Warnings and Precautions (5.6), Drug Interactions (7.1), Clinical Pharmacology (12.3)].
2.6 Treatment DiscontinuationFollowing discontinuation of Vraylar, the decline in plasma concentrations of active drug and metabolites may not be immediately reflected in patients’ clinical symptoms; the plasma concentration of cariprazine and its active metabolites will decline by 50% in ~1 week [see Clinical Pharmacology (12.3)]. There are no systematically collected data to specifically address switching patients from Vraylar to other antipsychotics or concerning concomitant administration with other antipsychotics.
3. DOSAGE FORMS AND STRENGTHSVraylar (cariprazine) capsules are available in four strengths.
· 1.5 mg capsules: White cap and body imprinted with “FL 1.5”
· 3 mg capsules: Green to blue-green cap and white body imprinted with “FL 3”
· 4.5 mg capsules: Green to blue-green cap and body imprinted with “FL 4.5”
· 6 mg capsules: Purple cap and white body imprinted with “FL 6”
4. CONTRAINDICATIONSVraylar is contraindicated in patients with history of a hypersensitivity reaction to cariprazine. Reactions have ranged from rash, pruritus, urticaria, and events suggestive of angioedema (e.g., swollen tongue, lip swelling, face edema, pharyngeal edema, and swelling face).
5. WARNINGS AND PRECAUTIONS5.1 Increased Mortality in Elderly Patients with Dementia-Related PsychosisAntipsychotic drugs increase the all-cause risk of death in elderly patients with dementia-related psychosis. Analyses of 17 dementia-related psychosis placebo-controlled trials (modal duration of 10 weeks and largely in patients taking atypical antipsychotic drugs) revealed a risk of death in the drug-treated patients of between 1.6 to 1.7 times that in placebo-treated patients. Over the course of a typical 10-week controlled trial, the rate of death in drug-treated patients was about 4.5%, compared to a rate of about 2.6% in placebo-treated patients.
Although the causes of death were varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature. Vraylar is not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning, Warnings and Precautions (5.3)].
5.2 Suicidal Thoughts and Behaviors in Children, Adolescents and Young AdultsIn pooled analyses of placebo-controlled trials of antidepressant drugs (SSRIs and other antidepressant classes) that included approximately 77,000 adult patients and 4,500 pediatric patients, the incidence of suicidal thoughts and behaviors in antidepressant-treated patients age 24 years and younger was greater than in placebo-treated patients. There was considerable variation in risk of suicidal thoughts and behaviors among drugs, but there was an increased risk identified in young patients for most drugs studied. There were differences in absolute risk of suicidal thoughts and behaviors across the different indications, with the highest incidence in patients with MDD. The drug-placebo differences in the number of cases of suicidal thoughts and behaviors per 1000 patients treated are provided in Table 1.

* Vraylar is not approved for use in pediatric patients.
It is unknown whether the risk of suicidal thoughts and behaviors in children, adolescents, and young adults extends to longer-term use, i.e., beyond four months. However, there is substantial evidence from placebo-controlled maintenance trials in adults with MDD that antidepressants delay the recurrence of depression and that depression itself is a risk factor for suicidal thoughts and behaviors.
Monitor all antidepressant-treated patients for any indication for clinical worsening and emergence of suicidal thoughts and behaviors, especially during the initial few months of drug therapy, and at times of dosage changes. Counsel family members or caregivers of patients to monitor for changes in behavior and to alert the healthcare provider. Consider changing the therapeutic regimen, including possibly discontinuing Vraylar, in patients whose depression is persistently worse, or who are experiencing emergent suicidal thoughts or behaviors.
5.3 Cerebrovascular Adverse Reactions, Including Stroke, in Elderly Patients with Dementia-Related PsychosisIn placebo-controlled trials in elderly subjects with dementia, patients randomized to risperidone, aripiprazole, and olanzapine had a higher incidence of stroke and transient ischemic attack, including fatal stroke. Vraylar is not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning, Warnings and Precautions (5.1)].
5.4 Neuroleptic Malignant Syndrome (NMS)Neuroleptic Malignant Syndrome (NMS), a potentially fatal symptom complex, has been reported in association with administration of antipsychotic drugs. Clinical manifestations of NMS are hyperpyrexia, muscle rigidity, delirium, and autonomic instability. Additional signs may include elevated creatine phosphokinase, myoglobinuria (rhabdomyolysis), and acute renal failure.
If NMS is suspected, immediately discontinue Vraylar and provide intensive symptomatic treatment and monitoring.
5.5 Tardive DyskinesiaTardive dyskinesia, a syndrome consisting of potentially irreversible, involuntary, dyskinetic movements, may develop in patients treated with antipsychotic drugs, including Vraylar. The risk appears to be highest among the elderly, especially elderly women, but it is not possible to predict which patients are likely to develop the syndrome. Whether antipsychotic drug products differ in their potential to cause tardive dyskinesia is unknown.
The risk of tardive dyskinesia and the likelihood that it will become irreversible increase with the duration of treatment and the cumulative dose. The syndrome can develop after a relatively brief treatment period, even at low doses. It may also occur after discontinuation of treatment.
Tardive dyskinesia may remit, partially or completely, if antipsychotic treatment is discontinued. Antipsychotic treatment itself, however, may suppress (or partially suppress) the signs and symptoms of the syndrome, possibly masking the underlying process. The effect that symptomatic suppression has upon the long-term course of tardive dyskinesia is unknown.
Given these considerations, Vraylar should be prescribed in a manner most likely to reduce the risk of tardive dyskinesia. Chronic antipsychotic treatment should generally be reserved for patients: 1) who suffer from a chronic illness that is known to respond to antipsychotic drugs; and 2) for whom alternative, effective, but potentially less harmful treatments are not available or appropriate. In patients who do require chronic treatment, use the lowest dose and the shortest duration of treatment producing a satisfactory clinical response should be sought. Periodically reassess the need for continued treatment.
If signs and symptoms of tardive dyskinesia appear in a patient on Vraylar, drug discontinuation should be considered. However, some patients may require treatment with Vraylar despite the presence of the syndrome.
5.6 Late-Occurring Adverse ReactionsAdverse events may first appear several weeks after the initiation of Vraylar treatment, probably because plasma levels of cariprazine and its major metabolites accumulate over time. As a result, the incidence of adverse reactions in short-term trials may not reflect the rates after longer term exposures [see Dosage and Administration (2.1), Adverse Reactions (6.1), Clinical Pharmacology (12.3)].
Monitor for adverse reactions, including extrapyramidal symptoms (EPS) or akathisia, and patient response for several weeks after a patient has begun Vraylar and after each dosage increase. Consider reducing the dose or discontinuing the drug.
5.7 Metabolic ChangesAtypical antipsychotic drugs, including Vraylar, have caused metabolic changes, including hyperglycemia, diabetes mellitus, dyslipidemia, and weight gain. Although all of the drugs in the class to date have been shown to produce some metabolic changes, each drug has its own specific risk profile.
Hyperglycemia and Diabetes Mellitus
Hyperglycemia, in some cases extreme and associated with ketoacidosis or hyperosmolar coma or death, has been reported in patients treated with atypical antipsychotics. Assess fasting plasma glucose before or soon after initiation of antipsychotic medication, and monitor periodically during long-term treatment.
Schizophrenia
In the 6-week, placebo-controlled trials of adult patients with schizophrenia, the proportion of patients with shifts in fasting glucose from normal (<100 mg/dL) to high (≥126 mg/dL) and borderline (≥100 and <126 mg/dL) to high were similar in patients treated with Vraylar and placebo. In the long-term, open-label schizophrenia studies, 4% patients with normal hemoglobin A1c baseline values developed elevated levels (≥6.5%).
Bipolar Disorder
In six, placebo-controlled trials up to 8-weeks of adult patients with bipolar disorder (mania or depression), the proportion of patients with shifts in fasting glucose from normal (<100 mg/dL) to high (≥126 mg/dL) and borderline (≥100 and <126 mg/dL) to high were similar in patients treated with Vraylar and placebo. In the long-term, open-label bipolar disorder studies, 4% patients with normal hemoglobin A1c baseline values developed elevated levels (≥6.5%).
Dyslipidemia
Atypical antipsychotics cause adverse alterations in lipids. Before or soon after initiation of antipsychotic medication, obtain a fasting lipid profile at baseline and monitor periodically during treatment.
Schizophrenia
In the 6-week, placebo-controlled trials of adult patients with schizophrenia, the proportion of patients with shifts in fasting total cholesterol, LDL, HDL and triglycerides were similar in patients treated with Vraylar and placebo.
Bipolar Disorder
In six placebo-controlled trials up to 8-weeks of adult patients with bipolar disorder (mania or depression), the proportion of patients with shifts in fasting total cholesterol, LDL, HDL and triglycerides were similar in patients treated with Vraylar and placebo.
Weight Gain
Weight gain has been observed with use of atypical antipsychotics, including Vraylar. Monitor weight at baseline and frequently thereafter. Tables 2, 3, and 4 show the change in body weight occurring from baseline to endpoint in 6-week schizophrenia, 3-week bipolar mania, and 6-week and 8-week bipolar depression trials, respectively.

Leukopenia and neutropenia have been reported during treatment with antipsychotic agents, including Vraylar. Agranulocytosis (including fatal cases) has been reported with other agents in the class.
Possible risk factors for leukopenia and neutropenia include pre-existing low white blood cell count (WBC) or absolute neutrophil count (ANC) and history of drug-induced leukopenia or neutropenia. In patients with a pre-existing low WBC or ANC or a history of drug-induced leukopenia or neutropenia, perform a complete blood count (CBC) frequently during the first few months of therapy. In such patients, consider discontinuation of Vraylar at the first sign of a clinically significant decline in WBC in the absence of other causative factors.
Monitor patients with clinically significant neutropenia for fever or other symptoms or signs of infection and treat promptly if such symptoms or signs occur. Discontinue Vraylar in patients with absolute neutrophil count < 1000/mm3 and follow their WBC until recovery.
5.9 Orthostatic Hypotension and SyncopeAtypical antipsychotics cause orthostatic hypotension and syncope. Generally, the risk is greatest during initial dose titration and when increasing the dose. Symptomatic orthostatic hypotension was infrequent in trials of Vraylar and was not more frequent on Vraylar than placebo. Syncope was not observed.
Orthostatic vital signs should be monitored in patients who are vulnerable to hypotension (e.g., elderly patients, patients with dehydration, hypovolemia, and concomitant treatment with antihypertensive medications), patients with known cardiovascular disease (history of myocardial infarction, ischemic heart disease, heart failure, or conduction abnormalities), and patients with cerebrovascular disease. Vraylar has not been evaluated in patients with a recent history of myocardial infarction or unstable cardiovascular disease. Such patients were excluded from pre-marketing clinical trials.
5.10 FallsAntipsychotics, including Vraylar may cause somnolence, postural hypotension, motor and sensory instability, which may lead to falls and, consequently, fractures or other injuries. For patients with diseases, conditions, or medications that could exacerbate these effects, complete fall risk assessments when initiating antipsychotic treatment and recurrently for patients on long-term antipsychotic therapy.
5.11 SeizuresLike other antipsychotic drugs, Vraylar may cause seizures. This risk is greatest in patients with a history of seizures or with conditions that lower the seizure threshold. Conditions that lower the seizure threshold may be more prevalent in older patients.
5.12 Potential for Cognitive and Motor ImpairmentVraylar, like other antipsychotics, has the potential to impair judgment, thinking, or motor skills.
In 6-week schizophrenia trials, somnolence (hypersomnia, sedation, and somnolence) was reported in 7% of Vraylar-treated patients compared to 6% of placebo-treated patients. In 3-week bipolar mania trials, somnolence was reported in 8% of Vraylar-treated patients compared to 4% of placebo-treated patients.
Patients should be cautioned about operating hazardous machinery, including motor vehicles, until they are reasonably certain that therapy with Vraylar does not affect them adversely.
5.13 Body Temperature DysregulationAtypical antipsychotics may disrupt the body’s ability to reduce core body temperature. Strenuous exercise, exposure to extreme heat, dehydration, and anticholinergic medications may contribute to an elevation in core body temperature; use Vraylar with caution in patient who may experience these conditions.
5.14 DysphagiaEsophageal dysmotility and aspiration have been associated with antipsychotic drug use. Dysphagia has been reported with Vraylar. Vraylar and other antipsychotic drugs should be used cautiously in patients at risk for aspiration.

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 practice.
The information below is derived from an integrated clinical study database for Vraylar consisting of 4753 adult patients exposed to one or more doses of Vraylar for the treatment of schizophrenia, manic or mixed episodes associated with bipolar I disorder, and bipolar depression in placebo-controlled studies. This experience corresponds with a total experience of 940.3 patient-years. A total of 2568 Vraylar-treated patients had at least 6 weeks and 296 Vraylar-treated patients had at least 48 weeks of exposure.
Patients with Schizophrenia
The following findings are based on four placebo-controlled, 6-week schizophrenia trials with Vraylar doses ranging from 1.5 to 12 mg once daily. The maximum recommended dosage is 6 mg daily.
Adverse Reactions Associated with Discontinuation of Treatment: There was no single adverse reaction leading to discontinuation that occurred at a rate of ≥ 2% in Vraylar-treated patients and at least twice the rate of placebo.
Common Adverse Reactions (≥ 5% and at least twice the rate of placebo): extrapyramidal symptoms and akathisia.
Adverse Reactions with an incidence of ≥ 2% and greater than placebo, at any dose are shown in Table 5.

Dystonia
Symptoms of dystonia, prolonged abnormal contractions of muscle groups, may occur in susceptible individuals during the first few days of treatment. Dystonic symptoms include: spasm of the neck muscles, sometimes progressing to tightness of the throat, swallowing difficulty, difficulty breathing, and/or protrusion of the tongue. Although these symptoms can occur at low doses, they occur more frequently and with greater severity with high potency and higher doses of first-generation antipsychotic drugs. An elevated risk of acute dystonia is observed in males and younger age groups.
Extrapyramidal Symptoms (EPS) and Akathisia
In schizophrenia, bipolar mania, and bipolar depression trials, data were objectively collected using the Simpson Angus Scale (SAS) for treatment-emergent EPS (parkinsonism) (SAS total score ≤ 3 at baseline and > 3 post-baseline) and the Barnes Akathisia Rating Scale (BARS) for treatment-emergent akathisia (BARS total score ≤ 2 at baseline and > 2 post-baseline).
In 6-week schizophrenia trials, the incidence of reported events related to extrapyramidal symptoms (EPS), excluding akathisia and restlessness was 17% for Vraylar-treated patients versus 8% for placebo-treated patients. These events led to discontinuation in 0.3% of Vraylar-treated patients versus 0.2% of placebo-treated patients. The incidence of akathisia was 11% for Vraylar-treated patients versus 4% for placebo-treated patients. These events led to discontinuation in 0.5% of Vraylar-treated patients versus 0.2% of placebo-treated patients. The incidence of EPS is shown in Table 8.

In the two 6-week and one 8-week bipolar depression trials, the incidence of reported events related to EPS, excluding akathisia and restlessness was 4% for Vraylar-treated patients versus 2% for placebo-treated patients. These events led to discontinuation in 0.4% of Vraylar-treated patients versus 0% of placebo-treated patients. The incidence of akathisia was 8% for Vraylar-treated patients versus 2% for placebo-treated patients. These events led to discontinuation in 1.5% of Vraylar-treated patients versus 0% of placebo-treated patients. The incidence of EPS is shown in Table 10.

Cataracts
In the long-term uncontrolled schizophrenia (48-week) and bipolar mania (16-week) trials, the incidence of cataracts was 0.1% and 0.2%, respectively. The development of cataracts was observed in nonclinical studies [see Nonclinical Toxicology (13.2)]. The possibility of lenticular changes or cataracts cannot be excluded at this time.
Vital Signs Changes
There were no clinically meaningful differences between Vraylar-treated patients and placebo-treated patients in mean change from baseline to endpoint in supine blood pressure parameters except for an increase in supine diastolic blood pressure in the 9 - 12 mg/day Vraylar-treated patients with schizophrenia.
Pooled data from 6-week schizophrenia trials are shown in Table 11 and from 3-week bipolar mania trials are shown in Table 12.

Changes in Laboratory Tests
The proportions of patients with transaminase elevations of ≥3 times the upper limits of the normal reference range in 6-week schizophrenia trials ranged between 1% and 2% for Vraylar-treated patients, increasing with dose, and was 1% for placebo-treated patients. The proportions of patients with transaminase elevations of ≥3 times the upper limits of the normal reference range in 3-week bipolar mania trials ranged between 2% and 4% for Vraylar-treated patients depending on dose group administered and 2% for placebo-treated patients. The proportions of patients with transaminase elevations of ≥3 times the upper limits of the normal reference range in 6-week and 8-week bipolar depression trials ranged between 0% and 0.5% for Vraylar-treated patients depending on dose group administered and 0.4% for placebo-treated patients.
The proportions of patients with elevations of creatine phosphokinase (CPK) greater than 1000 U/L in 6-week schizophrenia trials ranged between 4% and 6% for Vraylar-treated patients, increasing with dose, and was 4% for placebo-treated patients. The proportions of patients with elevations of CPK greater than 1000 U/L in 3-week bipolar mania trials was about 4% in Vraylar and placebo-treated patients. The proportions of patients with elevations of CPK greater than 1000 U/L in 6-week and 8-week bipolar depression trials ranged between 0.2% and 1% for Vraylar-treated patients versus 0.2% for placebo-treated patients.
Other Adverse Reactions Observed During the Pre-marketing Evaluation of Vraylar
Adverse reactions listed below were reported by patients treated with Vraylar at doses of ≥ 1.5 mg once daily within the premarketing database of 3988 Vraylar-treated patients. The reactions listed are those that could be of clinical importance, as well as reactions that are plausibly drug-related on pharmacologic or other grounds. Reactions that appear elsewhere in the Vraylar label are not included.
Reactions are further categorized by organ class and listed in order of decreasing frequency, according to the following definition: those occurring in at least 1/100 patients (frequent) [only those not already listed in the tabulated results from placebo-controlled studies appear in this listing]; those occurring in 1/100 to 1/1000 patients (infrequent); and those occurring in fewer than 1/1000 patients (rare).
Gastrointestinal Disorders: Infrequent: gastroesophageal reflux disease, gastritis
Hepatobiliary Disorders: Rare: hepatitis

7. DRUG INTERACTIONS 7.1 Drugs Having Clinically Important Interactions with Vraylar
Table 14. Clinically Important Drug Interactions with Vraylar |
|
Strong CYP3A4 Inhibitors |
|
Clinical Impact: |
Concomitant use of Vraylar with a strong CYP3A4 inhibitor increases the exposures of cariprazine and its major active metabolite, didesmethylcariprazine (DDCAR), compared to use of Vraylar alone [see Clinical Pharmacology (12.3)]. |
Intervention: |
If Vraylar is used with a strong CYP3A4 inhibitor, reduce Vraylar dosage [see Dosage and Administration (2.5)]. |
Examples: |
itraconazole, ketoconazole |
CYP3A4 Inducers |
|
Clinical Impact: |
CYP3A4 is responsible for the formation and elimination of the active metabolites of cariprazine. The effect of CYP3A4 inducers on the exposure of Vraylar has not been evaluated, and the net effect is unclear [see Clinical Pharmacology (12.3)]. |
Intervention: |
Concomitant use of Vraylar with a CYP3A4 inducer is not recommended [see Dosage and Administration (2.1, 2.5)]. |
Examples: |
rifampin, carbamazepine |
Pregnancy Exposure Registry
There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to Vraylar during pregnancy. For more information, contact the National Pregnancy Registry for Atypical Antipsychotics at 1-866-961-2388 or visit http://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/.
Risk Summary
Neonates exposed to antipsychotic drugs during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery (see Clinical Considerations). There are no available data on Vraylar use in pregnant women to inform any drug-associated risks for birth defects or miscarriage. The major active metabolite of cariprazine, DDCAR, has been detected in adult patients up to 12 weeks after discontinuation of Vraylar [see Clinical Pharmacology (12.3)].
Based on animal data, Vraylar may cause fetal harm.
Administration of cariprazine to rats during the period of organogenesis caused malformations, lower pup survival, and developmental delays at drug exposures less than the human exposure at the maximum recommended human dose (MRHD) of 6 mg/day. However, cariprazine was not teratogenic in rabbits at doses up to 4.6 times the MRHD of 6 mg/day [see Data].
The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. 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. Advise pregnant women of the potential risk to a fetus.
Clinical Considerations
Fetal/Neonatal Adverse Reactions
Extrapyramidal and/or withdrawal symptoms, including agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress and feeding disorder have been reported in neonates whose mothers were exposed to antipsychotic drugs during the third trimester of pregnancy. These symptoms have varied in severity. Some neonates recovered within hours or days without specific treatment; others required prolonged hospitalization. Monitor neonates for extrapyramidal and/or withdrawal symptoms and manage symptoms appropriately.
Data
Animal Data
Administration of cariprazine to pregnant rats during the period of organogenesis at oral doses of 0.5, 2.5, and 7.5 mg/kg/day which are 0.2 to 3.5 times the maximum recommended human dose (MRHD) of 6 mg/day based on AUC of total cariprazine (i.e. sum of cariprazine, DCAR, and DDCAR) caused fetal developmental toxicity at all doses which included reduced body weight, decreased male anogenital distance and skeletal malformations of bent limb bones, scapula and humerus. These effects occurred in the absence or presence of maternal toxicity. Maternal toxicity, observed as a reduction in body weight and food consumption, occurred at doses 1.2 and 3.5-times the MRHD of 6 mg/day based on AUC of total cariprazine. At these doses, cariprazine caused fetal external malformations (localized fetal thoracic edema), visceral variations (undeveloped/underdeveloped renal papillae and/or distended urethrae), and skeletal developmental variations (bent ribs, unossified sternebrae). Cariprazine had no effect on fetal survival.
Administration of cariprazine to pregnant rats during pregnancy and lactation at oral doses of 0.1, 0.3, and 1 mg/kg/day which are 0.03 to 0.4 times the MRHD of 6 mg/day based on AUC of total cariprazine caused a decrease in postnatal survival, birth weight, and post-weaning body weight of first generation pups at the dose that is 0.4 times the MRHD of 6 mg/day based on AUC of total cariprazine in absence of maternal toxicity. First generation pups also had pale, cold bodies and developmental delays (renal papillae not developed or underdeveloped and decreased auditory startle response in males). Reproductive performance of the first generation pups was unaffected; however, the second generation pups had clinical signs and lower body weight similar to those of the first generation pups.
Administration of cariprazine to pregnant rabbits during the period of organogenesis at oral doses of 0.1, 1, and 5 mg/kg/day, which are 0.02 to 4.6 times the MRHD of 6 mg/day based on AUC of total cariprazine was not teratogenic. Maternal body weight and food consumption were decreased at 4.6 times the MRHD of 6 mg/day based on AUC of total cariprazine; however, no adverse effects were observed on pregnancy parameters or reproductive organs.
8.2 LactationRisk Summary
Lactation studies have not been conducted to assess the presence of cariprazine in human milk, the effects on the breastfed infant, or the effects on milk production. Cariprazine is present in rat milk. The development and health benefits of breastfeeding should be considered along with the mother’s clinical need for Vraylar and any potential adverse effects on the breastfed infant from Vraylar or from the underlying maternal condition.
8.4 Pediatric UseSafety and effectiveness in pediatric patients have not been established. Pediatric studies of Vraylar have not been conducted. Antidepressants increased the risk of suicidal thoughts and behaviors in pediatric patients [see Boxed Warning, Warnings and Precautions (5.2)].
8.5 Geriatric UseClinical trials of Vraylar in the treatment of schizophrenia and bipolar mania did not include sufficient numbers of patients aged 65 and older to determine whether or not 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.
Elderly patients with dementia-related psychosis treated with Vraylar are at an increased risk of death compared to placebo. Vraylar is not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning and Warnings and Precautions (5.1, 5.3)].
8.6 Hepatic ImpairmentNo dosage adjustment for Vraylar is required in patients with mild to moderate hepatic impairment (Child-Pugh score between 5 and 9) [see Clinical Pharmacology (12.3)]. Usage of Vraylar is not recommended in patients with severe hepatic impairment (Child-Pugh score between 10 and 15). Vraylar has not been evaluated in this patient population.
8.7 Renal ImpairmentNo dosage adjustment for Vraylar is required in patients with mild to moderate (CrCL ≥ 30 mL/minute) renal impairment [see Clinical Pharmacology (12.3)].
Usage of Vraylar is not recommended in patients with severe renal impairment (CrCL < 30 mL/minute). Vraylar has not been evaluated in this patient population.
8.8 SmokingNo dosage adjustment for Vraylar is needed for patients who smoke. Vraylar is not a substrate for CYP1A2, smoking is not expected to have an effect on the pharmacokinetics of Vraylar.
8.9 Other Specific PopulationsNo dosage adjustment is required based on patient’s age, sex, or race. These factors do not affect the pharmacokinetics of Vraylar [see Clinical Pharmacology (12.3)].
9. DRUG ABUSE AND DEPENDENCE9.1 Controlled SubstanceVraylar is not a controlled substance.
9.2 AbuseVraylar has not been systematically studied in animals or humans for its abuse potential or its ability to induce tolerance.
9.3 DependenceVraylar has not been systematically studied in animals or humans for its potential for physical dependence.
10. OVERDOSAGE10.1 Human ExperienceIn pre-marketing clinical trials involving Vraylar in approximately 5000 patients or healthy subjects, accidental acute overdosage (48 mg/day) was reported in one patient. This patient experienced orthostasis and sedation. The patient fully recovered the same day.
10.2 Management of OverdosageNo specific antidotes for Vraylar are known. In managing overdose, provide supportive care, including close medical supervision and monitoring, and consider the possibility of multiple drug involvement. In case of an overdose, consult a Certified Poison Control Center (1-800-222-1222) for up-to-date guidance and advice.
11. DESCRIPTIONThe active ingredient of Vraylar is cariprazine HCl, an atypical antipsychotic. The chemical name is trans-N-{4-[2-[4-(2,3-dichlorophenyl)piperazine-1-yl]ethyl]cyclohexyl}-N’,N’-dimethylurea hydrochloride; its empirical formula is C21H33Cl3N4O and its molecular weight is 463.9 g/mol. The chemical structure is:
Vraylar capsules are intended for oral administration only. Each hard gelatin capsule contains a white to off-white powder of cariprazine HCl, which is equivalent to 1.5, 3, 4.5, or 6 mg of cariprazine base. In addition, capsules include the following inactive ingredients: gelatin, magnesium stearate, pregelatinized starch, shellac, and titanium dioxide. Colorants include black iron oxide (1.5, 3, and 6 mg), FD&C Blue 1 (3, 4.5, and 6 mg), FD&C Red 3 (6 mg), FD&C Red 40 (3 and 4.5 mg), or yellow iron oxide (3 and 4.5 mg).
12. CLINICAL PHARMACOLOGY12.1 Mechanism of ActionThe mechanism of action of cariprazine in schizophrenia and bipolar I disorder is unknown. However, the efficacy of cariprazine could be mediated through a combination of partial agonist activity at central dopamine D2 and serotonin 5-HT1A receptors and antagonist activity at serotonin 5-HT2A receptors. Cariprazine forms two major metabolites, desmethyl cariprazine (DCAR) and didesmethyl cariprazine (DDCAR), that have in vitro receptor binding profiles similar to the parent drug.
12.2 PharmacodynamicsCariprazine acts as a partial agonist at the dopamine D3 and D2 receptors with high binding affinity (Ki values 0.085 nM, and 0.49 nM (D2L) and 0.69 nM (D2S), respectively) and at the serotonin 5-HT1A receptors (Ki value 2.6 nM). Cariprazine acts as an antagonist at 5-HT2B and 5-HT2A receptors with high and moderate binding affinity (Ki values 0.58 nM and 18.8 nM respectively) as well as it binds to the histamine H1 receptors (Ki value 23.2 nM). Cariprazine shows lower binding affinity to the serotonin 5-HT2C and α1A- adrenergic receptors (Ki values 134 nM and 155 nM, respectively) and has no appreciable affinity for cholinergic muscarinic receptors (IC50>1000 nM).
Effect on QTc Interval
At a dose three-times the maximum recommended dose, cariprazine does not prolong the QTc interval to clinically relevant extent.
12.3 PharmacokineticsVraylar activity is thought to be mediated by cariprazine and its two major active metabolites, desmethyl cariprazine (DCAR) and didesmethyl cariprazine (DDCAR), which are pharmacologically equipotent to cariprazine.
After multiple dose administration of Vraylar, mean cariprazine and DCAR concentrations reached steady state at around Week 1 to Week 2 and mean DDCAR concentrations appeared to be approaching steady state at around Week 4 to Week 8 in a 12-week study (Figure 1). The half-lives based on time to reach steady state, estimated from the mean concentration-time curves, are 2 to 4 days for cariprazine, about 1 to 2 days for DCAR, and approximately 1 to 3 weeks for DDCAR. The time to reach steady state for the major active metabolite DDCAR was variable across patients, with some patients not achieving steady state at the end of the 12 week treatment [see Dosage and Administration (2.1), Warnings and Precautions (5.6)]. Mean concentrations of DCAR and DDCAR are approximately 30% and 400%, respectively, of cariprazine concentrations by the end of 12-week treatment.
After discontinuation of Vraylar, cariprazine, DCAR, and DDCAR plasma concentrations declined in a multi-exponential manner. Mean plasma concentrations of DDCAR decreased by about 50%, 1 week after the last dose and mean cariprazine and DCAR concentration dropped by about 50% in about 1 day. There was an approximately 90% decline in plasma exposure within 1 week for cariprazine and DCAR, and at about 4 weeks for DDCAR. Following a single dose of 1 mg of cariprazine administration, DDCAR remained detectable 8 weeks post-dose.
After multiple dosing of Vraylar, plasma exposure of cariprazine, DCAR, and DDCAR, increases approximately proportionally over the therapeutic dose range.

12-weeks of Treatment with Cariprazine 6 mg/daya
a Trough concentrations shown during treatment with cariprazine 6 mg/day.
SE: standard error; TOTAL CAR: sum concentration of cariprazine, DCAR and DDCAR; CAR: cariprazine
Absorption
After single dose administration of Vraylar, the peak plasma cariprazine concentration occurred in approximately 3-6 hours.
Administration of a single dose of 1.5 mg Vraylar capsule with a high-fat meal did not significantly affect the Cmax and AUC of cariprazine or DCAR.
Distribution
Cariprazine and its major active metabolites are highly bound (91 to 97%) to plasma proteins.
Elimination
Metabolism
Cariprazine is extensively metabolized by CYP3A4 and, to a lesser extent, by CYP2D6 to DCAR and DDCAR. DCAR is further metabolized into DDCAR by CYP3A4 and CYP2D6. DDCAR is then metabolized by CYP3A4 to a hydroxylated metabolite.
Excretion
Following administration of 12.5 mg/day cariprazine to patients with schizophrenia for 27 days, about 21% of the daily dose was found in urine, with approximately 1.2% of the daily dose was excreted in urine as unchanged cariprazine.
Studies in Specific Populations
Hepatic Impairment
Compared to healthy subjects, exposure (Cmax and AUC) in patients with either mild or moderate hepatic impairment (Child-Pugh score between 5 and 9) was approximately 25% higher for cariprazine and 20% to 30% lower for the major metabolites (DCAR and DDCAR) following daily doses of 0.5 mg cariprazine for 14 days [see Use in Specific Populations (8.6)].
Renal Impairment
Cariprazine and its major active metabolites are minimally excreted in urine. Pharmacokinetic analyses indicated no significant relationship between plasma clearance and creatinine clearance [see Use in Specific Populations (8.7)].
CYP2D6 Poor Metabolizers
CYP2D6 poor metabolizer status does not have clinically relevant effect on pharmacokinetics of cariprazine, DCAR, or DDCAR.
Age, Sex, Race
Age, sex, or race does not have clinically relevant effect on pharmacokinetics of cariprazine, DCAR, or DDCAR.
Drug Interaction Studies
In vitro studies
Cariprazine and its major active metabolites did not induce CYP1A2 and CYP3A4 enzymes and were weak inhibitors of CYP1A2, CYP2C9, CYP2D6, and CYP3A4 in vitro. Cariprazine was also a weak inhibitor of CYP2C19, CYP2A6, and CYP2E1 in vitro.
Cariprazine and its major active metabolites are not substrates of P-glycoprotein (P-gp), the organic anion transporting polypeptides 1B1 and 1B3 (OATP1B1 and OATP1B3), or the breast cancer resistance protein (BCRP).
Cariprazine and its major active metabolites were poor or non-inhibitors of transporters OATP1B1, OATP1B3, BCRP, organic cation transporter 2 (OCT2), and organic anion transporters 1 and 3 (OAT1 and OAT3) in vitro. The major active metabolites were also poor or non-inhibitors of transporter P-gp although cariprazine was probably a P-gp inhibitor based on the theoretical GI concentrations at high doses in vitro.
Based on in vitro studies, Vraylar is unlikely to cause clinically significant pharmacokinetic drug interactions with substrates of CYP1A2, CYP2A6, CYP2C9, CYP2C19, CYP2D6, CYP2E, and CYP3A4, or OATP1B1, OATP1B3, BCRP, OCT2, OAT1 and OAT3
In vivo studies
CYP 3A4 inhibitors
Co-administration of ketoconazole (400 mg/day), a strong CYP3A4 inhibitor, with Vraylar (0.5 mg/day) increased cariprazine Cmax and AUC0-24h by about 3.5-fold and 4-fold, respectively; increased DDCAR Cmax and AUC0-24h by about 1.5-fold; and decreased DCAR Cmax and AUC0-24h by about one-third. The impact of moderate CYP3A4 inhibitors has not been studied.
CYP3A4 inducers
CYP3A4 is responsible for the formation and elimination of the active metabolites of cariprazine. The effect of CYP3A4 inducers on the plasma exposure of cariprazine and its major active metabolites has not been evaluated, and the net effect is unclear.
CYP2D6 inhibitors
CYP2D6 inhibitors are not expected to influence pharmacokinetics of cariprazine, DCAR or DDCAR based on the observations in CYP2D6 poor metabolizers.
Proton pump inhibitors
Co-administration of pantoprazole (40 mg/day), a proton pump inhibitor, with Vraylar (6 mg/day) in patients with schizophrenia for 15 days did not affect cariprazine exposure at steady-state, based on Cmax and AUC0-24. Similarly, no significant change in exposure to DCAR and DDCAR was observed.
13. NONCLINICAL TOXICOLOGY13.1 Carcinogenesis, Mutagenesis, Impairment of FertilityCarcinogenesis
There was no increase in the incidence of tumors following daily oral administration of cariprazine to rats for 2 years and to Tg.rasH2 mice for 6 months at doses which are up to 4 and 19 times respectively, the MRHD of 6 mg/day based on AUC of total cariprazine, (i.e. sum of AUC values of cariprazine, DCAR and DDCAR).
Rats were administered cariprazine at oral doses of 0.25, 0.75, and 2.5 (males)/1, 2.5, and 7.5 mg/kg/day (females) which are 0.2 to 1.8 (males)/ 0.8 to 4.1 (females) times the MRHD of 6 mg/day based on AUC of total cariprazine.
Tg.rasH2 mice were administered cariprazine at oral doses of 1, 5, and 15 (males)/5, 15, and 50 mg/kg/day (females) which are 0.2 to 7.9 (males)/2.6 to 19 (females) times the MRHD of 6 mg/day based on AUC of total cariprazine.
Mutagenesis
Cariprazine was not mutagenic in the in vitro bacterial reverse mutation assay, nor clastogenic in the in vitro human lymphocyte chromosomal aberration assay or in the in vivo mouse bone marrow micronucleus assay. However, cariprazine increased the mutation frequency in the in vitro mouse lymphoma assay under conditions of metabolic activation. The major human metabolite DDCAR was not mutagenic in the in vitro bacterial reverse mutation assay, however, it was clastogenic and induced structural chromosomal aberration in the in vitro human lymphocyte chromosomal aberration assay.
Impairment of Fertility
Cariprazine was administered orally to male and female rats before mating, through mating and up to day 7 of gestation at doses of 1, 3, and 10 mg/kg/day which are 1.6 to 16 times the MRHD of 6 mg/day based on mg/m2. In female rats, lower fertility and conception indices were observed at all dose levels which are equal to or higher than 1.6 times the MRHD of 6 mg/day based on mg/m2. No effects on male fertility were noted at any dose up to 4.3 times the MRHD of 6 mg/day based on AUC of total cariprazine.
13.2 Animal Toxicology and/or PharmacologyCariprazine caused bilateral cataract and cystic degeneration of the retina in the dog following oral daily administration for 13 weeks and/or 1 year and retinal degeneration/atrophy in the rat following oral daily administration for 2 years. Cataract in the dog was observed at 4 mg/kg/day which is 7.1 (male) and 7.7 (female) times the MRHD of 6 mg/day based on AUC of total cariprazine. The NOEL for cataract and retinal toxicity in the dog is 2 mg/kg/day which is 5 (males) to 3.6 (females) times the MRHD of 6 mg/day based on AUC of total cariprazine. Increased incidence and severity of retinal degeneration/atrophy in the rat occurred at all doses tested, including the low dose of 0.75 mg/kg/day, at total cariprazine plasma levels less than clinical exposure (AUC) at the MRHD of 6 mg/day. Cataract was not observed in other repeat dose studies in pigmented mice or albino rats.
Phospholipidosis was observed in the lungs of rats, dogs, and mice (with or without inflammation) and in the adrenal gland cortex of dogs at clinically relevant exposures (AUC) of total cariprazine. Phospholipidosis was not reversible at the end of the 1-2 month drug-free periods. Inflammation was observed in the lungs of dogs dosed daily for 1 year with a NOEL of 1 mg/kg/day which is 2.7 (males) and 1.7 (females) times the MRHD of 6 mg/day based on AUC of total cariprazine. No inflammation was observed at the end of 2-month drug free period following administration of 2 mg/kg/day which is 5 (males) and 3.6 (females) times the MRHD of 6 mg/day based on AUC of total cariprazine; however, inflammation was still present at higher doses.
Hypertrophy of the adrenal gland cortex was observed at clinically relevant total cariprazine plasma concentrations in rats (females only) and mice following daily oral administration of cariprazine for 2 years and 6 months, respectively. Reversible hypertrophy/hyperplasia and vacuolation/vesiculation of the adrenal gland cortex were observed following daily oral administration of cariprazine to dogs for 1 year. The NOEL was 2 mg/kg/day which is 5 (males) and 3.6 (females) times the MRHD of 6 mg/day based on AUC of total cariprazine. The relevance of these findings to human risk is unknown.
14. CLINICAL STUDIES14.1 SchizophreniaThe efficacy of Vraylar for the treatment of schizophrenia was established in three, 6-week, randomized, double-blind, placebo-controlled trials in patients (aged 18 to 60 years) who met Diagnostic and Statistical Manual of Mental Disorders 4th edition, Text Revision (DSM-IV-TR) criteria for schizophrenia. An active control arm (risperidone or aripiprazole) was included in two trials to assess assay sensitivity. In all three trials, Vraylar was superior to placebo.
Positive and Negative Syndrome Scale (PANSS) and Clinical Global Impressions-Severity (CGI-S) rating scales were used as the primary and secondary efficacy measures, respectively, for assessing psychiatric signs and symptoms in each trial:
· PANSS is a 30-item scale that measures positive symptoms of schizophrenia (7 items), negative symptoms of schizophrenia (7 items), and general psychopathology (16 items), each rated on a scale of 1 (absent) to 7 (extreme). The PANSS total score may range from 30 to 210 with the higher score reflecting greater severity.
· The CGI-S is a validated clinician-related scale that measures the patient’s current illness state and overall clinical state on a 1 (normal, not at all ill) to 7-point (extremely ill) scale.
In each study, the primary endpoint was change from baseline in PANSS total score at the end of week 6. The change from baseline for Vraylar and active control groups was compared to placebo. The results of the trials are shown in Table 15. The time course of efficacy results of Study 2 is shown in Figure 2.
Study 1: In a 6-week, placebo-controlled trial (N = 711) involving three fixed doses of Vraylar (1.5, 3, or 4.5 mg/day) and an active control (risperidone), all Vraylar doses and the active control were superior to placebo on the PANSS total score and the CGI-S.
Study 2: In a 6-week, placebo-controlled trial (N = 604) involving two fixed doses of Vraylar (3 or 6 mg/day) and an active control (aripiprazole), both Vraylar doses and the active control were superior to placebo on the PANSS total score and the CGI-S.
Study 3: In a 6-week, placebo-controlled trial (N = 439) involving two flexible-dose range groups of Vraylar (3 to 6 mg/day or 6 to 9 mg/day), both Vraylar groups were superior to placebo on the PANSS total score and the CGI-S.
The efficacy of Vraylar was demonstrated at doses ranging from 1.5 to 9 mg/day compared to placebo. There was, however, a dose-related increase in certain adverse reactions, particularly above 6 mg. Therefore, the maximum recommended dose is 6 mg/day.
Examination of population subgroups based on age (there were few patients over 55), sex, and race did not suggest any clear evidence of differential responsiveness.

Figure 2 Change from Baseline in PANSS total score by weekly visits (Study 2)
The safety and efficacy of Vraylar as maintenance treatment in adults with schizophrenia were demonstrated in a randomized withdrawal trial that included 200 patients meeting DSM-IV criteria for schizophrenia who were clinically stable following 20 weeks of open-label cariprazine at doses of 3 to 9 mg/day. Patients were randomized to receive either placebo or cariprazine at the same dose for up to 72 weeks for observation of relapse. The primary endpoint was time to relapse. Relapse during the double-blind phase (DBP) was defined as meeting any one of the following criteria: hospitalization due to worsening of schizophrenia, increase in the PANSS total score by ≥ 30%, increase in CGI-S score by ≥ 2 points, deliberate self-injury, aggressive or violent behavior, clinically significant suicidal or homicidal ideation, or score >4 on one or more of the following PANSS items: delusions (P1), conceptual disorganization (P2), hallucination (P3), suspiciousness or persecution (P6), hostility (P7), uncooperativeness (G8), or poor impulse control (G14).
The efficacy of Vraylar was demonstrated at doses ranging from 3 to 9 mg/day compared to placebo. There was, however, a dose-related increase in certain adverse reactions, particularly above 6 mg. Therefore, the maximum recommended dose is 6 mg/day.
The Kaplan-Meier curves of the time to relapse during the double-blind, placebo-controlled, randomized withdrawal phase of the long-term trial are shown in Figure 3. Time to relapse was statistically significantly longer in the Vraylar-treated group compared to the placebo group.

DB = double-blind
*The maximum recommended daily dose is 6 mg. Doses above 6 mg daily do not confer increased effectiveness sufficient to outweigh dose-related adverse reactions.
14.2 Manic or Mixed Episodes Associated with Bipolar I DisorderThe efficacy of Vraylar in the acute treatment of bipolar mania was established in three, 3-week placebo-controlled trials in patients (mean age of 39 years, range 18 to 65 years) who met DSM-IV-TR criteria for bipolar 1 disorder with manic or mixed episodes with or without psychotic features. In all three trials, Vraylar was superior to placebo.
Young Mania Rating Scale (YMRS) and Clinical Global Impressions-Severity scale (CGI-S) were used as the primary and secondary efficacy measures, respectively, for assessing psychiatric signs and symptoms in each trial:
· The YMRS is an 11-item clinician-rated scale traditionally used to assess the degree of manic symptomatology. YMRS total score may range from 0 to 60 with a higher score reflecting greater severity.
· The CGI-S is validated clinician-related scale that measures the patient’s current illness state and overall clinical state on a 1 (normal, not at all ill) to 7-point (extremely ill) scale.
In each study, the primary endpoint was decrease from baseline in YMRS total score at the end of week 3. The change from baseline for each Vraylar dose group was compared to placebo. The results of the trials are shown in Table 16. The time course of efficacy results is shown in Figure 4.
Study 4: In a 3-week, placebo-controlled trial (N = 492) involving two flexible-dose range groups of Vraylar (3 to 6 mg/day or 6 to 12 mg/day), both Vraylar dose groups were superior to placebo on the YMRS total score and the CGI-S. The 6 to 12 mg/day dose group showed no additional advantage.
Study 5: In a 3-week, placebo-controlled trial (N = 235) involving a flexible-dose range of Vraylar (3 to 12 mg/day), Vraylar was superior to placebo on the YMRS total score and the CGI-S.
Study 6: In a 3-week, placebo-controlled trial (N = 310) involving a flexible-dose range of Vraylar (3 to 12 mg/day), Vraylar was superior to placebo on the YMRS total score and the CGI-S.
The efficacy of Vraylar was established at doses ranging from 3 to 12 mg/day. Doses above 6 mg did not appear to have additional benefit over lower doses (Table 16) and there was a dose-related increase in certain adverse reactions. Therefore, the maximum recommended dose is 6 mg/day.
Examination of population subgroups based on age (there were few patients over 55), sex, and race did not suggest any clear evidence of differential responsiveness.

14.3 Depressive Episodes Associated with Bipolar I Disorder (Bipolar Depression)The efficacy of Vraylar in the treatment of depressive episodes associated with bipolar I disorder (bipolar depression) was established in one 8-week and two 6-week placebo-controlled trials in patients (mean age of 41.6 years, range 18 to 65 years) who met DSM-IV-TR or DSM-5 criteria for depressive episodes associated with bipolar I disorder.
In each study, the primary endpoint was change from baseline in Montgomery-Asberg Depression Rating Scale (MADRS) total score at the end of Week 6. The MADRS is a 10-item clinician-rated scale with total scores ranging from 0 (no depressive features) to 60 (maximum score). The MADRS total score change from baseline for Vraylar compared to placebo is shown in Table 17. The time course of efficacy results of Study 8 is shown in Figure 5. In each study, the Vraylar 1.5 mg dose demonstrated statistical significance over placebo. The secondary endpoint was change from baseline to Week 6 in CGI-S. The CGI-S is validated clinician-related scale that measures the patient’s current illness state and overall clinical state on a 1 (normal, not at all ill) to 7-point (extremely ill) scale.
Study 7: In an 8-week, placebo-controlled trial (N = 571) involving three-fixed doses of Vraylar (0.75 mg/day, 1.5 mg/day, and 3 mg/day), Vraylar 1.5 mg was superior to placebo at end of Week 6 on the MADRS total score and the CGI-S.
Study 8: In a 6-week, placebo-controlled trial (N = 474) involving two-fixed doses of Vraylar (1.5 mg/day and 3 mg/day), Vraylar 1.5 mg and 3 mg were superior to placebo at end of Week 6 on the MADRS total score.
Study 9: In a 6-week, placebo-controlled trial (N = 478) involving two-fixed doses of Vraylar (1.5 mg/day and 3 mg/day), Vraylar 1.5 mg was superior to placebo at end of Week 6 on the MADRS total score and the CGI-S.
Examination of population subgroups based on age (there were few patients over 55), sex, and race did not suggest any clear evidence of differential responsiveness.

MEDICATION GUIDE |
What is the most important information I should know about Vraylar? Depression and other serious mental illnesses are the most important causes of suicidal thoughts and actions. Some people may have a particularly high risk of having suicidal thoughts or actions. These include people who have (or have a family history of) depression, bipolar illness (also called manic-depressive illness), or a history of suicidal thoughts or actions.
How can I watch for and try to prevent suicidal thoughts and actions in myself or a family member? Pay close attention to any changes, especially sudden changes in mood, behaviors, thoughts, or feelings. This is very important when an antidepressant medicine is started or when the dose is changed. Call the healthcare provider right away to report new or sudden changes in mood, behavior, thoughts, or feelings. Keep all follow-up visits with the healthcare provider as scheduled. Call the healthcare provider between visits as needed, especially if you have concerns about symptoms.
Call a healthcare provider right away if you or your family member has any of the following symptoms, especially if they are new, worse, or worry you: |

Vraylar may harm your unborn baby. Talk to your healthcare provider about the risk to your unborn baby if you take Vraylar during pregnancy. Tell your healthcare provider if you become pregnant or think you are pregnant during treatment with Vraylar. If you become pregnant during treatment with Vraylar, talk to your healthcare provider about registering with the National Pregnancy Registry for Atypical Antipsychotics. You can register by calling 1-866-961-2388 or go to http://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/. · are breastfeeding or plan to breastfeed. It is not known if Vraylar passes into your breast milk. Talk to your healthcare provider about the best way to feed your baby during treatment with Vraylar.
Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. |
How should I take Vraylar? |
What should I avoid while taking Vraylar? Do not exercise too much. In hot weather, stay inside in a cool place if possible. Stay out of the sun. Do not wear too much clothing or heavy clothing. Drink plenty of water. |
What are the possible side effects of Vraylar? · See “What is the most important information I should know about Vraylar?” · Stroke (cerebrovascular problems) in elderly people with dementia-related psychosis that can lead to death. · Neuroleptic malignant syndrome (NMS) is a serious condition that can lead to death. Call your healthcare provider or go to the nearest hospital emergency room right away if you have some or all of the following signs and symptoms of NMS:
○ high fever · Uncontrolled body movements (tardive dyskinesia). Vraylar may cause movements that you cannot control in your face, tongue, or other body parts. Tardive dyskinesia may not go away, even if you stop taking Vraylar. Tardive dyskinesia may also start after you stop taking Vraylar. · Late occurring side effects. Vraylar stays in your body for a long time. Some side effects may not happen right away and can start a few weeks after you start taking Vraylar, or if your dose of Vraylar increases. Your healthcare provider should monitor you for side effects for several weeks after you start and after any increase in your dose of Vraylar. · Problems with your metabolism such as:
○ high blood sugar (hyperglycemia) and diabetes. Increases in blood sugar can happen in some people who take Vraylar. Extremely high blood sugar can lead to coma or death. Your healthcare provider should check your blood sugar before you start, or soon after you start Vraylar, and then regularly during long-term treatment with Vraylar. increased fat levels (cholesterol and triglycerides) in your blood. Your healthcare provider should check the fat levels in your blood before you start, or soon after you start Vraylar, and then periodically during treatment with Vraylar. weight gain. You and your healthcare provider should check your weight before you start and often during treatment with Vraylar. · Low white blood cell count. Your healthcare provider may do blood tests during the first few months of treatment with Vraylar. · Decreased blood pressure (orthostatic hypotension). You may feel lightheaded or faint when you rise too quickly from a sitting or lying position. · Falls. Vraylar may make you sleepy or dizzy, may cause a decrease in your blood pressure when changing position (orthostatic hypotension), and can slow your thinking and motor skills which may lead to falls that can cause fractures or other injuries. · Seizures (convulsions). · Problems controlling your body temperature so that you feel too warm. See “What should I avoid while taking Vraylar?” · Difficulty swallowing that can cause food or liquid to get into your lungs.
The most common side effects of Vraylar include: difficulty moving or slow movements, tremors, uncontrolled body movements, restlessness and feeling like you need to move around, sleepiness, nausea, vomiting, and indigestion. |
How should I store Vraylar? · Store Vraylar at room temperature, between 68°F to 77°F (20°C to 25°C). Keep Vraylar and all medicines out of the reach of children. |
