批准日期:2014年11月
公司:Genzyme
FDA已批准LemtradaTM(阿仑单抗)为有复发性多发性硬化症(MS)患者的治疗
Genzyme,一个Sanofi 的公司,今天宣布美国食品药品监督管理局(FDA)已批准LemtradaTM(阿仑单抗)为有复发性多发性硬化症(MS)患者的治疗。因为其安全性图形,Lemtrada的使用一般应保留对对MS适用的两种或更多药物治疗反应不足的患者。
Genzyme总裁和CEO,David Meeker说“今天的批准是Genzyme超过10年开发Lemtrada的巅峰 ”“在两项研究中Lemtrada显示疗效优于Rebif 对年复发率的本批准的基础。为了有助于确定治疗检测和处理严重风险将开始一项全面风险评价和缓解策略(REMS)。”
FDA批准Lemtrada是根据两项至关重要随机化III期开放评价盲态研究比较治疗用Lemtrada 与Rebif®(高剂量皮下干扰素β-1a)患者有复发缓解型MS或新治疗(CARE-MS I)或东对以前治疗复发(CARE-MS II)。
在CARE-MS I试验中,在减低年复发率Lemtrada是比干扰素β-1a更显著有效;在延缓残疾进展中观察到差别未到达统计显著性。在CARE-MS II试验中,Lemtrada是比干扰素β-1a更显著有效在减低年复发率,和在给予Lemtrada患者相比干扰素β-1a残疾的积累显著减慢。对Lemtrada临床发展计划设计接近1,500患者有超过6,400 患者-年安全性随访,
德州多发性硬化症临床中心主任Edward Fox,M.D.,Ph.D.说:“MS 的未满足需求仍旧高”“在美国对于有复发性MS生活是伟大的一天,将取到这个新有意义治疗”。
Lemtrada的说明书包括一项黑框警告注意一种严重,有时致命性自身免疫情况,严重和危及生命输注反应的风险和还注意Lemtrada可能引起恶性病包括甲状腺癌,黑色素瘤和淋巴增殖性疾病风险增加。
只能通过限制性分配计划得到Lemtrada,Lemtrada REMS(风险评价和减缓战略)。已发展这个计划在美国只有被证实处方者,医疗机构和专门药房才能得到Lemtrada 和还确保患者被纳入REMS计划。计划意向帮助教育卫生保健提供者和患者严重风险伴随Lemtrada和按要求在末次输注后48个月适当定期监视支持检测这些风险。REMS是根据被成功地在2期和3期实施的一个发展风险处理疾患和允许早期检测和处理伴随Lemtrada的某些严重风险。
国家MS协会处政务宣传,服务和研究主任Timothy Coetzee博士说:“FDA批准Lemtrada对于在美国有复发性MS生活人们已认识到是有意义的里程碑,我们很高兴听到,MS社会的声音和有复发MS人们现将得到一种新,需要的治疗选择。“
Lemtrada的两个年治疗疗程有独特给药和给予时间表。第一个治疗疗程通过静脉输注在5个连续天给药,而第二个疗程在其后12个月3个连续天。
Lemtrada的最常见副作用是皮疹,头痛,发热,鼻咽炎,恶心,泌尿道感染,疲乏,失眠,上呼吸道感染,疱疹病毒感染,荨麻疹,瘙痒,甲状腺疾病,真菌感染,关节痛,肢体痛,背痛,腹泻,窦炎,食道疼痛,感觉异常,眩晕,腹痛,潮红,和呕吐。伴随Lemtrada其他严重副作用包括自自身免疫甲状腺病,自身免疫全血细胞减少,感染和肺炎。
在2013年9月首先在欧盟批准,在40多个国家批准Lemtrada。世界范围监管机构正在进行另外上市申请审评。
FDA Lemtrada的批准标志Genzyme在美国第二个被批准MS治疗。2012年9月Genzyme接受FDA 批准其1天次,口服Aubagio®(特立氟胺[teriflunomide])为治疗复发性MS。Aubagio在50多个国家被批准,和在另外监管机构审评下。用Aubagio临床试验和商业治疗使用间接近30,000患者。
多发性硬化症估计全球侵犯多于2.3百万人。在美国有接近400,000人有MS生活。
关于Lemtrada 对美国患者重要安全性资料
接受Lemtrada患者中可能发生严重和危及生命自身免疫情况例如免疫血小板减少(ITP)和抗肾小球基底膜病。监视完整血细胞计数与分类,血清肌酐水平,和接受Lemtrada患者中定期间隔尿分析与细胞计数。Lemtrada是伴随严重和危及生命输注反应。Lemtrada可能只在有证书有一个地点得到仪器医疗情况和经过处理过敏样反应和严重输注反应训练的人员下给予。 Lemtrada可能伴随恶性病风险增加,包括甲状腺癌,黑色素瘤和淋巴增殖性疾病。Lemtrada REMS计划,正在实施一个有频繁监视的全面风险管理计划,有助于减轻这些严重风险。
Lemtrada说明书包括一个黑框警告注意一种严重,有时致命性自身免疫情况,严重和危及生命输注反应的风险和还注意Lemtrada可能致恶性病包括甲状腺癌,黑色素瘤和淋巴增殖性疾病风险的增加。在有人类免疫缺陷病毒(HIV)感染患者禁忌用Lemtrada。
美国适应证和用途
Lemtrada是适用为有复发性多发性硬化症(MS)患者的治疗。因为其安全性图形,Lemtrada的使用一般应保留为对两种或更多适用为MS治疗药物反应不足的患者。
关于Lemtrada™(阿仑单抗)
阿仑单抗是一种靶向CD52单克隆抗体,这是T和B细胞上富集的蛋白。循环T和B细胞被认为是在MS中对损伤性炎症过程负责。每个疗程后阿仑单抗耗尽循环T和B淋巴细胞。然后随时间淋巴细胞计数增加对不同的淋巴细胞亚型重建淋巴细胞群。
在CARE-MS I试验中,在减低年复发率Lemtrada是比干扰素β-1a更显著有效(对Lemtrada为0.18和对干扰素β-1a为0.39 (p<0.0001)相对减低55%。在两年时观察到有残疾进展患者比例差别没有达到统计显著性(对Lemtrada为8%和对干扰素β-1a为11% (p=0.22)),相对风险减低30%。在两年时对Lemtrada保持无复发患者的%为78%相比较对干扰素β-1a为59% (p<0.0001)。T2病变体检从基线变化%没有达到统计显著性(对Lemtrada为-9.3和对干扰素β-1a为-6.5,p=0.31)。
在CARE-MS II试验中,在减低年复发率Lemtrada是比干扰素β-1a更显著有效(对Lemtrada为0.26和对干扰素β-1a为0.52,p<0.0001,相对减低49%)。对Lemtrada有确证6个月残疾进展的患者比例显著较低(对Lemtrada为13%相比对干扰素β-1a为21%,p=0.0084),相对风险减低42%. Thef在两年时保持无复发患者的%对Lemtrada为65%相比较对干扰素β-1a为47% (p<0.0001)。T2病变体积从基线的变化%没有达到统计显著性(对Lemtrada为-1.3和对干扰素β-1a为-1.2,p=0.14)。
这些重点不包括安全和有效使用LEMTRADA所需所有资料。请参阅LEMTRADA完整处方资料。

在感染有人类免疫缺陷病毒(HIV)患者禁忌LEMTRADA因为LEMTRADA致CD4+淋巴细胞计数延长减低。
5 警告和注意事项
5.1 自身免疫
治疗用LEMTRADA可能导致自身抗体的形成和严重自身免疫阶段情况的风险增加。在临床研究中LEMTRADA治疗患者经受甲状腺疾病(34%),免疫血小板减少(2%),和肾小球肾病(0.3%)[见警告和注意事项(5.5,5.6,5.7)]。
自身免疫溶血性贫血和自身免疫全血细胞减少[见警告和注意事项(5.8)],未在0.2%患者各自发生分化结缔组织疾病,和获得性甲型血友病(抗-因子VIII抗体)。0.1%患者发生类风湿性关节炎,I型糖尿病,白癜风,和视网膜色素上皮病变。上市后使用期间,另外自身免疫事件包括Guillain-Barré综合征和用B-细胞慢性淋巴细胞白血病(B-CLL)治疗患者,一般地比MS推荐较高更频剂量中曾报道慢性炎症性脱髓鞘性多发性神经根神经病,以及其他疾病。一例用阿仑单抗治疗的肿瘤患者有致命性输注伴随移植物抗宿主病。
妊娠期间从母亲可能传输自身抗体至胎儿。母亲阿仑单抗治疗后发生一例抗促甲状腺激素受体抗体导致新生儿甲状腺机能亢进[Graves’ disease] [见特殊人群中使用(8.1)]。
因为用LEMTRADA自身抗体形成宽广范围的风险LEMTRADA可能增加其他自身免疫情况。
开始治疗前和然后在LEMTRADA的末次剂量后每月间隔共48个月监视完全学细胞计数与分类,血清肌酐水平,和尿分析与尿细胞计数以求早期检测和治疗自身免疫不良反应[见剂量和给药方法(2.6)]。根据临床发现自身免疫提示测试后48个月应进行检测。
只有在REMS下通过受限制计划可得到LEMTRADA[见警告和注意事项(5.4)]。
5.2 输注反应
LEMTRADA致细胞因子释放综合征导致输注反应,其中有些可能是严重和危及生命。在临床研究中,LEMTRADA治疗患者的92%经受输注反应。在有些患者中,被报道LEMTRADA输注输注反应后多于24小时。在3%患者发生严重反应和2例患者包括过敏性反应(包括过敏性休克),血管水肿,支气管痉挛,低血压,胸痛,心动过缓,心动过速(包括房颤),transient neurologic 症状,低血压,头痛,发热,和皮疹. Other 输注反应 包括恶心,荨麻疹,瘙痒,失眠,chills,潮红,疲乏,呼吸困难,肺侵润,味觉障碍,消化不良,眩晕,和疼痛。在临床研究中,有输注反应患者0.6%接受肾上腺素或阿托品。
上市后使用期间,在有B-CLL,以及其他疾病患者治疗中曾报道,一般地在比MS中推荐较高和更频剂量时其他严重和有时致命性输注反应包括缺氧,昏厥,急性呼吸窘迫综合征,呼吸骤停,心肌梗死,急性心功能不全,和心脏骤停。
每个疗程头3天LEMTRADA输注前立即患者用皮质类固醇预先给药。在临床试验中,每个LEMTRADA疗程患者接受甲泼尼龙1,000 mg。LEMTRADA给药前考虑用抗组织胺和/或降热药预治疗。尽管预治疗输注反应可能发生。
易患心血管或肺受损患者另外考虑监视医学情况。
只能在可得到仪器和人员受过处理输注反应(包括过敏性反应和心和呼吸紧急事件)地点由经认证卫生保健情况下给予LEMTRADA。
只能通过REMS下受限制计划得到LEMTRADA[见警告和注意事项(5.4)]。
5.3 恶性病
甲状腺癌
LEMTRADA可能增加甲状腺癌的风险。在对照临床研究中,3/919(0.3%) LEMTRADA-治疗患者发生甲状腺癌,与之比较在干扰素β-1a-治疗组没有。但是,在LEMTRADA-治疗组更频繁进行对甲状腺癌筛选,因为在那些患者自身免疫甲状腺疾病发生率较高。在非对照研究在LEMTRADA-治疗患者发生另外两例甲状腺癌。
患者和卫生保健提供者应监视甲状腺癌症状包括颈部新肿块或肿胀,颈前方疼痛,持续声音嘶哑或其他声音变化,吞咽或呼吸困难,或不由于上呼吸道感染持续咳嗽。
黑色素瘤
LEMTRADA可能增加黑色素瘤的风险。在非对照研究中,4/1486(0.3%)LEMTRADA-治疗患者发生黑色素瘤或原位黑色素瘤。那些患者之一有局部进展疾病证据。
接受LEMTRADA患者进行基线和每年皮肤检查监视黑色素瘤。
淋巴增殖性疾病和淋巴瘤
有MSLEMTRADA-治疗患者曾发生淋巴增殖性疾病和淋巴瘤,包括一例MALT淋巴瘤,Castleman病,和非-Epstein Barr病毒-相关Burkitt氏淋巴瘤治疗后死亡。在非-MS患者上市后有Epstein Barr病毒相关淋巴增殖性疾病报告。
因为LEMTRADA是一种免疫调节治疗,在有预先存在或正在进行恶性病患者应谨慎开始LEMTRADA。
只能通过REMS下受限制计划得到LEMTRADA[见警告和注意事项(5.4)]。
5.4 LEMTRADA REMS计划
只能通过REMS被称为下受限制计划LEMTRADA REMS计划得到LEMTRADA,因为自身免疫,输注反应和恶性病的风险[见警告和注意事项(5.1,5.2,5.3)].
LEMTRADA REMS计划的令人注目要求包括以下:
●处方者必须通过纳入和完成训练有计划认证。
●患者必须纳入在计划和符合现行监视要求[见剂量和给药方法(2.6)].
●药房必须有计划认证和必须唯一认证授权接受LEMTRADA分发医疗机构。
●医疗结构必须纳入计划和证实患者在输注LEMTRADA前被授权。医疗机构必须有得到仪器和受过处理输注反应训练人员的地点。
5.5 免疫血小板减少
在MS临床研究中2%的LEMTRADA-治疗患者发生免疫血小板减少(ITP)。
在有MS患者一项对照临床试验中,一例LEMTRADA-治疗患者发生未识别的ITP前实施每月血监视要求,和死于脑内出血。在MS临床研究中作为ITP的结果,2%的所有LEMTRADA-治疗患者发生血小板计数最低值每微升≤20,000细胞。抗-血小板抗体不能防止ITP发生。末次LEMTRADA剂量后大于3年被诊断免疫血小板减少ITP。
免疫血小板减少ITP的症状包括容易瘀伤,瘀斑,自发性粘膜皮肤出血(如,鼻出血,咯血),和比正常较重或不规则月经出血。.
咯血也可能是抗肾小球基底膜(GBM)病指示[见警告和注意事项(5.6)],和必须进行适当鉴别诊断。提醒患者对他们可能经受症状保存警惕症状和如有任何担忧立即寻求医学帮助。
开始治疗前和其后在每个月间隔直至末次输注后48个月得到完全血细胞计数(CBCs)与分类 [见剂量和给药方法(2.6)]。在这个阶段后,根据临床发现提示性ITP应进行测试。如怀疑ITP应立即得到一个完全血细胞计数。如ITP发作被确证,及时开始适当医学干预。
5.6 肾小球肾病
在MS临床试验中0.3%的LEMTRADA-治疗患者发生肾小球肾病。有3例膜性肾小球肾炎和2 例抗肾小球基底膜病。用阿仑单抗治疗MS患者有发表的和上市后发生抗肾小球基底膜病和随后发生肾病终末期需要肾移植。抗肾小球基底膜病病例曾被诊断直至LEMTRADA末次剂量后的40个月。需要禁忌评价和治疗因为抗肾小球基底膜病可能导致肾衰竭需要透析或移植和如不治疗可能危及生命。
肾病变的临床表现包括肌酐水平升高,血尿,或蛋白尿。肺泡[Alveolar]出血表现为咯血是抗肾小球基底膜病常见组分但在临床试验没有发生。
开始治疗前和其后在每个月间隔直至末次输注后48个月得到血清肌酐水平和尿分析与细胞计数。在这个时间阶段后,应根据临床发现提示性肾病进行测试。
如血清肌酐从基线临床意义变化,观察到不能解释血尿,或蛋白尿对肾病进一步评价。
肾病的早期检测和治疗可能降低结局差的风险。
5.7 甲状腺疾病
在临床研究中34%的LEMTRADA-治疗患者发生自身免疫甲状腺疾病。首次LEMTRADA剂量后7年以上无对照临床研究随访阶段自始至终发生新诊断甲状腺疾病。自身免疫甲状腺疾病s 包括Graves氏病,甲状腺机能亢进,和甲状腺功能低下。1%的LEMTRADA-治疗患者发生有视力减低的Graves氏眼病,眼疼痛,和突眼症。两例患者需要手术眼框减压术。在临床研究中约2%的LEMTRADA-治疗患者中发生严重甲状腺事件和包括伴甲状腺病心脏和精神事件。所有LEMTRADA-治疗患者,3%进行甲状腺切除术。.
妊娠妇女中甲状腺病具有特殊风险[见特殊人群中使用(8.1)].
开始治疗前和每3个月其后直至末次输注后个月得到甲,例如TSH水平。如临床上指示在48个月后继续测试甲状腺功能。
在有现有甲状腺疾病患者中只有潜在获益胜过潜在风险才应给予LEMTRADA。
5.8 其他自身免疫血细胞减少
在MS临床研究中LEMTRADA-治疗患者发生自身免疫全血细胞减少例如中性粒细胞减少(0.1%),溶血性贫血(0.2%),和全血细胞减少(0.2%)。
在自身免疫溶血性贫血的病例中,患者对直接抗球蛋白抗体测试阳性,和血红蛋白水平最低值范围从2.9-8.6 g/dL。自身免疫溶血性贫血的症状包括软弱,胸痛,黄疸,尿暗色,和心动过速。一例LEMTRADA-治疗患者有自身免疫全血细胞减少死于脓毒血症。
上市后使用期间,另外自身免疫全血细胞减少包括致死性自身免疫溶血性贫血和有B-CLL患者治疗曾报道再生障碍性贫血,以及其他疾病,一般地比MS中推荐剂量更高和更频。
用CBC结果监视全血细胞减少。如指示确证全血细胞减少及时医学干预。
5.9 感染
在对照临床试验在MS直至2年时间LEMTRADA-治疗患者发生感染71%与之比较用干扰素β-1a治疗患者为53%。
LEMTRADA-治疗患者比干扰素β-1a患者更经常发生感染包括鼻咽炎,泌尿道感染,上呼吸道感染,窦炎,疱疹感染,流感,和支气管炎。用LEMTRADA治疗患者3%发生严重感染与之比较用干扰素β-1a治疗患者为1%。LEMTRADA组中严重感染包括:阑尾炎,胃肠炎,肺炎,带状疱疹,和牙感染。
LEMTRADA疗程后不要给或病毒疫苗。用LEMTRADA治疗患者免疫已改变和给予活病毒疫苗后可能处在感染风险增加。
有活动性感染患者中考虑延迟LEMTRADA给药直至感染被完全控制。
LEMTRADA与抗肿瘤或免疫抑制治疗同时使用可能增加免疫抑制的风险。
疱疹病毒感染
在对照临床试验中,16%的LEMTRADA-治疗患者发生疱疹病毒感染与之比较干扰素β-1a患者3%。这些事件包括口腔疱疹(8.8%),带状疱疹(4.2%),单纯疱疹(1.8%),和生殖器疱疹(1.3%)。在LEMTRADA-治疗中严重疱疹感染患者包括原发性水痘(0.1%),带状疱疹(0.2%),和疱疹性脑膜炎(0.1%)。
为预防带状疱疹在适当抑制性给药方案给予抗病毒药。对疱疹病毒感染在每个疗程头一天开始给予抗病毒预防和治疗用LEMTRADA治疗后继续最小2个月或直至CD4+淋巴细胞计数是 > 每微升200 细胞,以后发生哪个为准[见剂量和给药方法(2.3)]。
人类乳头状瘤病毒
宫颈人类乳头状瘤病毒(HPV)感染,包括宫颈不典型增生,在2%的LEMTRADA-治疗患者发生。对女性患者建议每年HPV筛选.
结核
在对照临床试验中在用LEMTRADA和干扰素β-1a治疗患者中发生结核。在0.3%的LEMTRADA-治疗患者发生活动性和潜伏结核病例,在流行区最常见。LEMTRADA开始前按照当地指导原则进行结核筛选。对在结核筛选测试阳性患者,用LEMTRADA治疗前用标准医护实践治疗。
真菌感染
在MS对照临床试验中真菌感染,尤其是口和阴道念珠菌,在LEMTRADA-治疗患者(12%)比用干扰素β-1a治疗患者(3%)更常发生。
李斯特菌感染
LEMTRADA-治疗患者中曾报道李斯特菌脑膜炎。李斯特菌脑膜炎病例发生在阿仑单抗给药1个月内。对李斯特菌脑膜炎增加的时间不清楚。患者应避免李斯特菌单核细胞增生潜在来源或适当地加热食物。
在非-MS患者中感染
上市后使用期间,有B-CLL患者治疗中曾报道严重和有时致死性病毒,细菌,原虫,和真菌感染,包括有些由于潜伏感染的再活化,以及其他疾病,一般地比在多发性硬化症[MS]推荐剂量更高和更频。
肝炎
不能得到对伴LEMTRADA与乙型肝炎病毒(HBV)或丙型肝炎病毒(HCV)再活化数据因为有活动性或慢性感染证据患者从临床试验被排除。LEMTRADA开始前考虑筛选处在高危HBV和/或HCV感染风险患者和HBV和/或被鉴定为HCV携带者患者处方LEMTRADA谨慎对待因为这些患者可能处在不可逆肝脏损伤风险,由于他们预先存在状态结果,相对潜在病毒再活化。
5.10 肺炎
在临床研究中,6/1217例(0.5%) LEMTRADA-治疗患者有不同严重程度的肺炎。在临床研究中发生超敏性肺炎和有纤维化肺炎。患者应被忠告报告肺炎症状,包括气短,咳嗽,喘息,胸痛或胸闷,和咯血。
5.11 有相同活性成分的药品
LEMTRADA含如同CAMPATH®相同的活性成分(阿仑单抗)。
如LEMTRADA被考虑为以前曾接受CAMPATH患者中使用,需增加对免疫系统相加和长时间持续的警惕。

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。
在对照临床试验(研究1和研究2),总共811例复发型MS患者接受LEMTRADA。总共811例患者接受1个疗程治疗,和在12个月时789例患者接受第二个疗程治疗。在对照试验中总体随访是等同1622例患者年,有一个另外的3411人-年随访开放延伸研究。人群是18-55岁,65%为女性,和92%是高加索人。
最常见不良反应
在临床试验中,用LEMTRADA最常见不良反应(至少10%患者和比干扰素β-1a更频)是皮疹,头痛,发热,鼻咽炎,恶心,泌尿道感染,疲乏,失眠,上呼吸道感染,疱疹病毒感染,荨麻疹,瘙痒,甲状腺疾病,真菌感染,关节炎,肢体痛,背痛,腹泻,窦炎,口咽痛,感觉异常,眩晕,腹痛,潮红,和呕吐。
表1列举在研究1和2治疗患者发生比干扰素β-1a相同和较高率不良反应。
淋巴细胞减少
在MS临床试验中接近所有(99.9%)用LEMTRADA治疗患者经历淋巴细胞减少。在每个治疗疗程中最低淋巴细胞计数发生在约1个月后。对治疗疗程1和2LEMTRADA治疗1个月后均数淋巴细胞计数分别为0.25 × 109L(范围0.02-2.30 × 109L)和0.32(0.02-1.81 × 109L)。每个LEMTRADA治疗疗程后6个月,每个疗程后约40%患者在6个月后淋巴细胞总计数增加至达到正常的较低限和约80%患者在12个月[见临床药理学(12.2)]。
6.3 自杀行为和意念
在临床研究中,LEMTRADA和干扰素β-1a组两者都有0.6%患者有意向自杀或自杀意念的事件。在任何一个临床研究治疗组中都没有完成自杀。自杀行为和意念发生在有或无精神病或甲状腺疾病史患者。忠告患者立即报告任何抑郁或自杀意念的症状至处方医生。
6.4 免疫原性
如所有治疗性蛋白,有对免疫原性潜能。使用一种酶联免疫吸附分析(ELISA)和一种竞争性结合分析,在第1,3,1个月(疗程1检测到)抗-阿仑单抗结合抗体分别为LEMTRADA-治疗患者的62%,67%,29%和以及在第13,15,和24个月(疗程2),分别检测到LEMTRADA治疗患者83%,83%,和75%。对结合抗体测试阳性的样品进一步评价用流式细胞计量仪在体外评价 抑制作用的证据。在阳性结合抗体患者第1,3,12个月(疗程1)分别检测到87%,46%,和5%;以及在第13,15,和24个月(疗程2)94%,88%,和42%的有阳性结合抗体患者检测到中和抗体。在疗程2期间抗阿仑单抗抗体伴随阿仑单抗浓度减低而疗程1不伴随。从临床试验没有证据存在抗-阿仑单抗抗体结合或抑制作用对临床结局,总淋巴细胞计数,或不良事件的显著影响。抗体的发生率高度依赖于分析的灵敏度和特异性。此外,在某个分析中观察到抗体的阳性发生率(包括抑制性抗体)可能受几种因素影响包括分析方法学,样品处置,采样时间,同时药物,和所患疾病。因为这些原因,比较对LEMTRADA抗体的发生率与其他产品抗体的发生率可能是误导。
6.5 上市后经验
以下不良反应,在其他地方没有描述,阿仑单抗(CAMPATH)为B-细胞慢性淋巴细胞白血病(B-CLL)的治疗使用批准期间以及为治疗其他疾病时鉴定,一般地比治疗MS推荐剂量更高和更频(如,30 mg)。因为这些反应是从人群大小不确定志愿报道的,并非总能可靠估计它们的频数或确定与药物保留因果相互关系。
心脏疾病
在非-MS患者以前用潜在地心脏读者药物治疗充血性慢性心力衰竭,心肌病变,和射血分量减低。
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。在妊娠huCD52转基因小鼠当器官形成期间给药时LEMTRADA是胚胎致死。给予LEMTRADA后可能发生自身-抗体。
曾报道抗-甲状腺抗体的胎盘转移 导致新生儿甲状腺机能亢进。妊娠期间只有潜在获益胜过对胎儿潜在风险才应使用LEMTRADA。
动物数据
当LEMTRADA在器官形成期(妊娠天[GD]6-10或GD 11-15)给予妊娠huCD52转基因小鼠剂量3或10 mg/kg IV,未观察到致畸胎作用。但是,在妊娠GD 11-15期间给药动物致胚胎死亡增加(植入后丢失增加和所有胎鼠死亡或被吸收的母兽数)。
在妊娠huCD52转基因小鼠一项分开研究,在器官形成期间(GD 6-10或GD 11-15)给予LEMTRADA剂量3或10 mg/kg/IV,在两个测试剂量在子代中骏观察到B淋巴细胞和T-淋巴细胞群减低。未曾适当地评估在器官形成期给予LEMTRADA对产后发育的影响。
临床考虑
避免在子宫内暴露于LEMTRADA,育儿潜能妇女当接受用LEMTRADA治疗疗程和疗程治疗后共4个月应使用有效避孕措施。
LEMTRADA诱发持久甲状腺疾病s[见警告和注意事项(5.7)]。妊娠复律中为治疗的甲状腺低下症增加流产风险和可能对胎儿有影响包括智力低下和侏儒症。有甲状腺机能亢进的母亲中,在治疗用阿仑单抗后发生甲状腺机能亢进患者,抗促甲状腺激素受体抗体的胎盘转运导致阿仑单抗给药后1年后生产的婴儿,她的有甲状腺风暴[storm]新生儿甲状腺机能亢进[见警告和注意事项(5.1)]。
8.3 哺乳母亲
产后第8至第12天给予哺乳小鼠LEMTRAD 10 mg/kg,在哺乳小鼠乳汁中检测到阿仑单抗。在产后第13天,哺乳小鼠和子代血清阿仑单抗的水平相似,和在子代中伴随药理学活性的证据 (淋巴细胞计数减低)。
不知道阿仑单抗是否排泄在人乳汁。因为许多药物排泄在乳汁中,和因为哺乳婴儿来自LEMTRADA的潜在严重不良反应,应做出决定是否继续哺乳或终止药物,考虑药物对母亲的重要性。
8.4 儿童使用
尚未确定在小于17岁患儿中安全性和有效性。由于在儿童患者中自身免疫,输注反应,和因为可能增加的风险恶性病风险(甲状腺,黑色素瘤,淋巴增殖性疾病,和淋巴瘤),建议在儿童患者中不使用LEMTRADA[见警告和注意事项(5.1,5.2,5.3)]。
8.5 老年人使用
LEMTRADA的临床研究没有包括足够数量65岁和以上患者不能确定他们的反应是否不同于较年轻患者。
10 药物过量
两例MS患者在单次意外输注60 mg的LEMTRADA后经受严重反应(头痛,皮疹,和或低血压或窦性心动过速)。LEMTRADA的剂量大于推荐剂量可能增加输注反应或其免疫效应的强度或时间。对阿仑单抗药物过量没有已知的解毒药。
11 一般描述
LEMTRADA(阿仑单抗)是一种重组人源化IgG1 kappa单抗指向细胞表面糖蛋白,CD52。阿仑单抗有分子量接近150kD。LEMTRADA是在 is produced in哺乳动物细胞中国仓鼠卵巢细胞) 悬浮培养营养介质含新霉素。在最终产品中未检测到新霉素。LEMTRADA是一种无菌,透明和无色至浅黄色,溶液(pH 7.2±0.2)为输注。
每1 mL溶液含阿仑单抗10 mg,磷酸氢二钠(1.15 mg),依地酸二钠二水(0.0187 mg),聚山梨醇80(0.1 mg),氯化钾(0.2 mg),磷酸二氢钾(0.2 mg),氯化钠(8 mg),和注射用水。
12 临床药理学
12.1 作用机制
阿仑单抗在多发性硬化症发挥其治疗作用的精确机制不知道但是被假设涉及与CD52结合,T和B淋巴细胞上,和天然杀伤细胞,单核细胞,和巨噬细胞上存在的一种细胞表面抗原。结合至T和B淋巴细胞细胞表面后,阿仑单抗导致抗体依赖性细胞溶解和补体介导溶解。
12.2 药效动力学
LEMTRADA对淋巴细胞群的影响
LEMTRADA每个疗程后耗尽循环T和B淋巴细胞。在临床试验中,最低细胞计数发生在治疗疗程后1个月第一次治疗后血细胞计数时。然后淋巴细胞计数随时间增加:B细胞计数通常在6个月内恢复;T细胞计数增加更缓慢和在治疗后12个月通常仍低于基线。每个疗程后6个月约60%患者有总淋巴细胞计数低于正常的低限和在12个月后有20%患者计数低于正常低限。
淋巴细胞群的重建对不同的淋巴细胞亚型不一样。在临床试验中在第一个月时均数CD4+淋巴细胞计数为40细胞每微升,和,在第12月时,每微升270细胞。在第30个月时,约半数患者有CD4+淋巴细胞计数仍低于正常低限。
心脏电生理学
在一项研究53例MS患者,阿仑单抗12 mg每天共5天没有致在QTc间隔变化大于20ms。在首次输注后至少2小时观察到心率增加均数22至26跳每分但随后输注未观察到。
12.3 药代动力学
在总共148例有MS的复发型接受12 mg/day在连续5天,第一个疗程后12个月接着连续3天12 mg/day患者中评价LEMTRADA的药代动力学。
吸收
在一个治疗疗程内血清浓度随连续剂量给药而增加,在末次输注后发生最高观察浓度。在第一个疗程的第5天均数最高浓度为3014 ng/mL,和第二个疗程第3天均数最高浓度2276 ng/mL。
分布
LEMTRADA被很大地限制至血液和间质空间有中央室分布容积14.1 L。
消除
消除半衰期是约2周和疗程间有可比性。每个疗程后约30天内血清浓度是一般地不能检测到 (< 60 ng/mL)。
特殊人群
年龄,种族,或性别对LEMTRADA的药代动力学没有影响。
13 非临床毒理学
13.1 癌发生,突变发生,生育力受损
尚未进行研究评估LEMTRADA的致癌性或遗传毒性潜能。
当huCD52转基因雄性小鼠与未处理野生型雌性小鼠同居前连续5天给予LEMTRADA(3或10 mg/kg IV)至雄性小鼠,未观察到对生育力或生殖行为影响。但是,两个测试剂量都观察到对精子参数不良效应(包括异常形态学[脱落/无头]和总计数和运动性减低)。
huCD52转基因雌性小鼠与未处理野生型雄性同居前给予LEMTRADA(3或10 mg/kg IV)连续5天,黄体和植入部位均数减低和植入后丢失增加,导致较高测试剂量较少活胚胎。
14 临床研究

WARNING
AUTOIMMUNITY, INFUSION REACTIONS, AND MALIGNANCIES
· LEMTRADA causes serious, sometimes fatal, autoimmune conditions such as immune thrombocytopenia and anti-glomerular basement membrane disease. Monitor complete blood counts with differential, serum creatinine levels, and urinalysis with urine cell counts at periodic intervals for 48 months after the last dose of LEMTRADA [see WARNINGS AND PRECAUTIONS].
· LEMTRADA causes serious and life threatening infusion reactions. LEMTRADA must be administered in a setting with appropriate equipment and personnel to manage anaphylaxis or serious infusion reactions. Monitor patients for two hours after each infusion. Make patients aware that serious infusion reactions can also occur after the 2hour monitoring period [see WARNINGS AND PRECAUTIONS].
· LEMTRADA may cause an increased risk of malignancies, including thyroid cancer, melanoma, and lymphoproliferative disorders. Perform baseline and yearly skin exams [see WARNINGS AND PRECAUTIONS].
· Because of the risk of autoimmunity, infusion reactions, and malignancies, LEMTRADA is available only through restricted distribution under a Risk Evaluation Mitigation Strategy (REMS) Program. Call 1-855-676-6326 to enroll in the LEMTRADA REMS program [see WARNINGS AND PRECAUTIONS].
DESCRIPTIONLEMTRADA (alemtuzumab) is a recombinant humanized IgG1 kappa monoclonal antibody directed against the cell surface glycoprotein, CD52. Alemtuzumab has an approximate molecular weight of 150 kD. LEMTRADA is produced in mammalian cell (Chinese hamster ovary) suspension culture in a nutrient medium containing neomycin. Neomycin is not detectable in the final product. LEMTRADA is a sterile, clear and colorless to slightly yellow, solution (pH 7.2 ± 0.2) for infusion.
Each 1 mL of solution contains alemtuzumab 10 mg, dibasic sodium phosphate (1.15 mg), disodium edetate dihydrate (0.0187 mg), polysorbate 80 (0.1 mg), potassium chloride (0.2 mg), potassium dihydrogen phosphate (0.2 mg), sodium chloride (8 mg), and water for injection.
Indications & Dosage
INDICATIONSLEMTRADA is indicated for the treatment of patients with relapsing forms of multiple sclerosis (MS). Because of its safety profile, the use of LEMTRADA should generally be reserved for patients who have had an inadequate response to two or more drugs indicated for the treatment of MS.
DOSAGE AND ADMINISTRATIONDosage InformationThe recommended dosage of LEMTRADA is 12 mg/day administered by intravenous infusion for 2 treatment courses:
· First Treatment Course: 12 mg/day on 5 consecutive days (60 mg total dose)
· Second Treatment Course: 12 mg/day on 3 consecutive days (36 mg total dose) administered 12 months after the first treatment course.
Testing And Procedures Prior To TreatmentBaseline laboratory tests are required prior to treatment with LEMTRADA [see Laboratory Testing and Monitoring to Assess Safety]. In addition, prior to starting treatment with LEMTRADA [see WARNINGS AND PRECAUTIONS]:
· complete any necessary immunizations at least 6 weeks prior to treatment
· determine whether patients have a history of varicella or have been vaccinated for varicella zoster virus (VZV). If not, test the patient for antibodies to VZV and consider vaccination for those who are antibody-negative. Postpone treatment with LEMTRADA until 6 weeks after VZV vaccination.
· perform tuberculosis screening according to local guidelines
· instruct patients to avoid potential sources of Listeria monocytogenes
Recommended Premedication And Concomitant MedicationCorticosteroidsPremedicate patients with high dose corticosteroids (1,000 mg methylprednisolone or equivalent) immediately prior to LEMTRADA infusion and for the first 3 days of each treatment course [see WARNINGS AND PRECAUTIONS].
Herpes ProphylaxisAdminister anti-viral prophylaxis for herpetic viral infections starting on the first day of each treatment course and continue for a minimum of two months following treatment with LEMTRADA or until the CD4+ lymphocyte count is ≥200 cells per microliter, whichever occurs later [seeWARNINGS AND PRECAUTIONS].
Preparation InstructionsFollow the steps below to prepare the diluted solution of LEMTRADA for intravenous infusion:
· Inspect LEMTRADA visually for particulate matter and discoloration prior to administration. Do not use if particulate matter is present or the solution is discolored. Do not freeze or shake vials prior to use.
· Withdraw 1.2 mL of LEMTRADA from the vial into a syringe using aseptic technique and inject into a 100 mL bag of sterile 0.9% Sodium Chloride, USP or 5% Dextrose in Water, USP.
· Gently invert the bag to mix the solution. Ensure the sterility of the prepared solution, because it contains no antimicrobial preservatives. Each vial is for single use only.
Prior to administration, protect diluted LEMTRADA solution from light and store for as long as 8 hours either at room temperature 15°C to 25°C (59°F to 77°F) or keep refrigerated at conditions 2°C to 8°C (36°F to 46°F).
Infusion InstructionsInfuse LEMTRADA over 4 hours starting within 8 hours after dilution. Extend the duration of the infusion if clinically indicated.
Administer LEMTRADA in a setting in which equipment and personnel to appropriately manage anaphylaxis or serious infusion reactions are available [see WARNINGS AND PRECAUTIONS].
Do not add or simultaneously infuse other drug substances through the same intravenous line. Do not administer as an intravenous push or bolus.
Monitor vital signs before the infusion and periodically during the infusion. Provide appropriate symptomatic treatment for infusion reactions as needed. Consider immediate discontinuation of the intravenous infusion if severe infusion reactions occur.
Observe patients for infusion reactions during and for at least 2 hours after each LEMTRADA infusion. Consider longer periods of observation if clinically indicated. Inform patients that they should report symptoms that occur during and after each infusion because they may indicate a need for prompt medical intervention [see WARNINGS AND PRECAUTIONS].
Laboratory Testing And Monitoring To Assess SafetyConduct the following laboratory tests at baseline and at periodic intervals for 48 months following the last treatment course of LEMTRADA in order to monitor for early signs of potentially serious adverse effects:
· Complete blood count (CBC) with differential (prior to treatment initiation and at monthly intervals thereafter)
· Serum creatinine levels (prior to treatment initiation and at monthly intervals thereafter)
· Urinalysis with urine cell counts (prior to treatment initiation and at monthly intervals thereafter)
· A test of thyroid function, such as thyroid stimulating hormone (TSH) level (prior to treatment initiation and every 3 months thereafter)
Conduct baseline and yearly skin exams to monitor for melanoma [see WARNINGS AND PRECAUTIONS].

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.
In controlled clinical trials (Study 1 and Study 2), a total of 811 patients with relapsing forms of MS received LEMTRADA. A total of 811 patients received 1 course of therapy, and 789 patients received a second course of therapy at 12 months. The overall follow-up in the controlled trials was equivalent to 1622 patient years, with an additional 3411 person-years of follow-up in an open-label extensionstudy. The population was 18-55 years of age, 65% were female, and 92% were Caucasian.
Most Common Adverse ReactionsIn clinical trials, the most common adverse reactions with LEMTRADA (in at least 10% of patients and more frequently than in interferon beta-1a) were rash, headache, pyrexia, nasopharyngitis, nausea,urinary tract infection, fatigue, insomnia, upper respiratory tract infection, herpes viral infection, urticaria, pruritus, thyroid gland disorders, fungal infection, arthralgia, pain in extremity, back pain, diarrhea, sinusitis, oropharyngeal pain, paresthesia, dizziness, abdominal pain, flushing, and vomiting.
Table 1 lists adverse reactions occurring in ≥5% of LEMTRADA-treated patients in Study 1 and 2 and at the same or at a higher rate than interferon beta-1a.

Nearly all (99.9%) patients treated with LEMTRADA in MS clinical trials experienced lymphopenia. The lowest lymphocyte counts occurred approximately by 1 month after each course of treatment. The mean lymphocyte count at 1 month after LEMTRADA treatment was 0.25 x 109 L (range 0.02-2.30 x 109 L) and 0.32 (0.02-1.81 x 109 L) for treatment courses 1 and 2, respectively. Total lymphocyte counts increased to reach the lower limit of normal in approximately 40% of patients by 6 months after each LEMTRADA treatment course and approximately 80% of patients by 12 months after each course [see CLINICAL PHARMACOLOGY].
Suicidal Behavior Or IdeationIn clinical studies, 0.6% of patients in both the LEMTRADA and interferon beta-1a groups had events of attempted suicide or suicidal ideation. There were no completed suicides in either clinical study treatment group. Suicidal behavior or ideation occurred in patients with or without a history of a psychiatric or thyroid disorder. Advise patients to report immediately any symptoms of depression or suicidal ideation to the prescribing physician.
ImmunogenicityAs with all therapeutic proteins, there is potential for immunogenicity. Using an enzyme-linked immunosorbent assay (ELISA) and a competitive binding assay, anti-alemtuzumab binding antibodies were detected in 62%, 67%, and 29% of LEMTRADA-treated patients, at months 1, 3, 12 (Course 1) as well as 83%, 83%, and 75% of LEMTRADA-treated patients at months 13, 15, and 24 (Course 2). Samples that tested positive for binding antibodies were further evaluated for evidence of in vitro inhibition using a flow cytometry assay. Neutralizing antibodies were detected in 87%, 46%, and 5% of positive binding antibody patients at months 1, 3, 12 (Course 1) as well as 94%, 88%, and 42% of positive binding antibody patients at months 13, 15, and 24 (Course 2). Anti-alemtuzumab antibodies were associated with decreased alemtuzumab concentration during Course 2 but not Course 1. There was no evidence from clinical trials that the presence of binding or inhibitory anti-alemtuzumab antibodies had a significant effect on clinical outcomes, total lymphocyte count, or adverse events.
The incidence of antibodies is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including inhibitory antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to LEMTRADA with the incidence of antibodies to other products may be misleading.
Postmarketing ExperienceThe following adverse reactions have been identified during post-approval use of alemtuzumab. 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.
Postmarketing Experience With LEMTRADAGastrointestinal System Disorders: Acute acalculous cholecystitis.
Postmarketing Experience With CAMPATHCAMPATH is approved for the treatment of B-cell chronic lymphocytic leukemia (B-CLL) and is generally administered at higher and more frequent doses (e.g., 30 mg) than recommended in the treatment of MS.
Cardiac Disorders: Congestive heart failure, cardiomyopathy, and decreased ejection fraction in non-MS patients previously treated with potentially cardiotoxic agents.

Warnings & Precautions
WARNINGSIncluded as part of the PRECAUTIONS section.
PRECAUTIONSAutoimmunityTreatment with LEMTRADA can result in the formation of autoantibodies and increase the risk of serious autoimmune mediated conditions. In clinical studies, LEMTRADA-treated patients experienced thyroid disorders (34%), immune thrombocytopenia (2%), and glomerular nephropathies (0.3%) [see sections on Immune Thrombocytopenia, Glomerular Nephropathies and Thyroid Disorders]. Autoimmune hemolytic anemia and autoimmune pancytopenia [see Other Autoimmune Cytopenias], undifferentiated connective tissue disorders, and acquired hemophilia A (anti-Factor VIII antibodies) each occurred in 0.2% of patients. Rheumatoid arthritis, type I diabetes, vitiligo, and retinal pigment epitheliopathy occurred in 0.1% of patients.
During postmarketing use, additional autoimmune events including Guillain-Barré syndrome and chronic inflammatory demyelinating polyradiculoneuropathy have been reported in the treatment of patients with B-cell chronic lymphocytic leukemia (B-CLL), as well as other disorders, generally at higher and more frequent doses than recommended in MS. An oncology patient treated with alemtuzumab had fatal transfusion-associated graft-versus-host disease.
Autoantibodies may be transferred from the mother to the fetus during pregnancy. A case of transplacental transfer of anti-thyrotropin receptor antibodies resulting in neonatal Graves' diseaseoccurred after alemtuzumab treatment in the mother [see Use In Specific Populations].
LEMTRADA may increase the risk of other autoimmune conditions because of the broad range of autoantibody formation with LEMTRADA.
Monitor complete blood counts with differential, serum creatinine levels, and urinalysis with urine cell counts before starting treatment and then at monthly intervals for 48 months after the last dose of LEMTRADA to allow for early detection and treatment of autoimmune adverse reactions [see DOSAGE AND ADMINISTRATION]. After 48 months, testing should be performed based on clinical findings suggestive of autoimmunity.
LEMTRADA is available only through a restricted program under a REMS [see LEMTRADA REMS Program].
Infusion ReactionsLEMTRADA causes cytokine release syndrome resulting in infusion reactions, some of which may be serious and life threatening. In clinical studies, 92% of LEMTRADA-treated patients experienced infusion reactions. In some patients, infusion reactions were reported more than 24 hours after LEMTRADA infusion. Serious reactions occurred in 3% of patients and included anaphylaxis in 2 patients (including anaphylactic shock), angioedema, bronchospasm, hypotension, chest pain, bradycardia, tachycardia (including atrial fibrillation), transient neurologic symptoms, hypertension, headache, pyrexia, and rash. Other infusion reactions included nausea, urticaria, pruritus, insomnia, chills, flushing, fatigue, dyspnea, pulmonary infiltrates, dysgeusia, dyspepsia, dizziness, and pain. In clinical studies, 0.6% of patients with infusion reactions received epinephrine or atropine.
During postmarketing use, other serious and sometimes fatal infusion reactions included hypoxia, syncope, acute respiratory distress syndrome, respiratory arrest, myocardial infarction, acute cardiac insufficiency, and cardiac arrest have been reported in the treatment of patients with B-CLL, as well as other disorders, generally at higher and more frequent doses than recommended in MS.
Premedicate patients with corticosteroids immediately prior to LEMTRADA infusion for the first 3 days of each treatment course. In clinical studies, patients received 1,000 mg of methylprednisolone for the first 3 days of each LEMTRADA treatment course. Consider pretreatment with antihistaminesand/or antipyretics prior to LEMTRADA administration. Infusion reactions may occur despite pretreatment.
Consider additional monitoring in patients with medical conditions which predispose them to cardiovascular or pulmonary compromise.
LEMTRADA can only be administered in certified healthcare settings that have on-site access to equipment and personnel trained to manage infusion reactions (including anaphylaxis and cardiac and respiratory emergencies).
LEMTRADA is available only through a restricted program under a REMS [see LEMTRADA REMS Program].
MalignanciesThyroid CancerLEMTRADA may increase the risk of thyroid cancer. In controlled clinical studies, 3 of 919 (0.3%) LEMTRADA-treated patients developed thyroid cancer, compared to none in the interferon beta-1a–treated group. However, screening for thyroid cancer was performed more frequently in the LEMTRADA-treated group, because of the higher incidence of autoimmune thyroid disorders in those patients. Two additional cases of thyroid cancer in LEMTRADA-treated patients occurred in uncontrolled studies.
Patients and healthcare providers should monitor for symptoms of thyroid cancer including a new lump or swelling in the neck, pain in the front of the neck, persistent hoarseness or other voice changes, trouble swallowing or breathing, or a constant cough not due to an upper respiratory tract infection.
MelanomaLEMTRADA may increase the risk of melanoma. In uncontrolled studies, 4 of 1486 (0.3%) LEMTRADA-treated patients developed melanoma or melanoma in situ. One of those patients had evidence of locally advanced disease.
Perform baseline and yearly skin examinations to monitor for melanoma in patients receiving LEMTRADA.
Lymphoproliferative Disorders And LymphomaCases of lymphoproliferative disorders and lymphoma have occurred in LEMTRADA-treated patients with MS, including a MALT lymphoma, Castleman's Disease, and a fatality following treatment of non-Epstein Barr Virus–associated Burkitt's lymphoma. There are postmarketing reports of Epstein Barr Virus–associated lymphoproliferative disorders in non-MS patients.
Because LEMTRADA is an immunomodulatory therapy, caution should also be exercised in initiating LEMTRADA in patients with preexisting or ongoing malignancies.
LEMTRADA is available only through a restricted program under a REMS [see LEMTRADA REMS Program].
LEMTRADA REMS Program
LEMTRADA is available only through a restricted program under a REMS called the LEMTRADA REMS Program because of the risks of autoimmunity, infusion reactions, and malignancies [see sections above on Autoimmunity,
Infusion Reactions and Malignancies].
Notable requirements of the LEMTRADA REMS Program include the following:
· Prescribers must be certified with the program by enrolling and completing training.
· Patients must enroll in the program and comply with ongoing monitoring requirements [see DOSAGE AND ADMINISTRATION].
· Pharmacies must be certified with the program and must only dispense to certified healthcare facilities that are authorized to receive LEMTRADA.
· Healthcare facilities must enroll in the program and verify that patients are authorized before infusing LEMTRADA. Healthcare facilities must have on-site access to equipment and personnel trained to manage infusion reactions.
Further information, including a list of qualified healthcare facilities, is available at 1-855-6766326.
Immune ThrombocytopeniaImmune thrombocytopenia (ITP) occurred in 2% of LEMTRADA-treated patients in clinical studies in MS.
In a controlled clinical study in patients with MS, one LEMTRADA-treated patient developed ITP that went unrecognized prior to the implementation of monthly blood monitoring requirements, and died from intracerebral hemorrhage. Nadir platelet counts ≤20,000 cells per microliter as a result of ITP occurred in 2% of all LEMTRADA-treated patients in clinical studies in MS. Anti-platelet antibodies did not precede ITP onset. ITP has been diagnosed more than 3 years after the last LEMTRADA dose.
Symptoms of ITP include easy bruising, petechiae, spontaneous mucocutaneous bleeding (e.g., epistaxis, hemoptysis), and heavier than normal or irregular menstrual bleeding. Hemoptysis may also be indicative of anti-glomerular basement membrane (GBM) disease [see Glomerular Nephropathies], and an appropriate differential diagnosis has to be undertaken. Remind the patient to remain vigilant for symptoms they may experience and to seek immediate medical help if they have any concerns.
Obtain complete blood counts (CBCs) with differential prior to initiation of treatment and at monthly intervals thereafter until 48 months after the last infusion [see DOSAGE AND ADMINISTRATION]. After this period of time, testing should be performed based on clinical findings suggestive of ITP. If ITP is suspected, a complete blood count should be obtained immediately. If ITP onset is confirmed, promptly initiate appropriate medical intervention.
Glomerular NephropathiesGlomerular nephropathies occurred in 0.3% of LEMTRADA-treated patients in MS clinical studies. There were 3 cases of membranous glomerulonephritis and 2 cases of anti-glomerular basement membrane (anti-GBM) disease. There are published and postmarketing cases of MS patients treated with alemtuzumab who developed anti-GBM disease and subsequently developed end-stage renal disease requiring renal transplantation. Cases of anti-GBM disease have been diagnosed up to 40 months after the last dose of LEMTRADA. Urgent evaluation and treatment is required because anti-GBM disease can lead to renal failure requiring dialysis or transplantation and can be life-threatening if left untreated.
Clinical manifestations of nephropathy may include elevated serum creatinine levels, hematuria, or proteinuria. Alveolar hemorrhage manifested as hemoptysis is a common component of anti-GBM disease but did not occur in clinical studies.
Obtain serum creatinine levels and urinalysis with cell counts prior to initiation of treatment and at monthly intervals thereafter until 48 months after the last infusion. After this period of time, testing should be performed based on clinical findings suggestive of nephropathies.
If clinically significant changes from baseline in serum creatinine, unexplained hematuria, or proteinuria are observed, perform further evaluation for nephropathies. Early detection and treatment of nephropathies may decrease the risk of poor outcomes.
Thyroid DisordersAutoimmune thyroid disorders occurred in 34% of LEMTRADA-treated patients in clinical studies. Newly diagnosed thyroid disorders occurred throughout the uncontrolled clinical study follow-up period, more than 7 years after the first LEMTRADA dose. Autoimmune thyroid disorders included Graves' disease, hyperthyroidism and hypothyroidism. Graves' ophthalmopathy with decreased vision, eye pain, and exophthalmos occurred in 1% of LEMTRADA-treated patients. Two patients required surgical orbital decompression. Serious thyroid events occurred in about 2% of LEMTRADA-treated patients in clinical studies and included cardiac and psychiatric events associated with thyroid disease. Of all LEMTRADA-treated patients, 3% underwent thyroidectomy.
Thyroid disease poses special risks in women who are pregnant [see Use In Specific Populations].
Obtain thyroid function tests, such as TSH levels, prior to initiation of treatment and every 3 months thereafter until 48 months after the last infusion. Continue to test thyroid function after 48 months if clinically indicated.
In patients with ongoing thyroid disorder, LEMTRADA should be administered only if the potential benefit justifies the potential risks.
Other Autoimmune CytopeniasAutoimmune cytopenias such as neutropenia (0.1%), hemolytic anemia (0.2%), and pancytopenia (0.2%) occurred in LEMTRADA-treated patients in clinical studies in MS. In cases of autoimmune hemolytic anemia, patients tested positive for direct antiglobulin antibodies, and nadir hemoglobinlevels ranged from 2.9-8.6 g/dL. Symptoms of autoimmune hemolytic anemia include weakness, chest pain, jaundice, dark urine, and tachycardia. One LEMTRADA-treated patient with autoimmune pancytopenia died from sepsis.
During postmarketing use, additional autoimmune cytopenias including fatal autoimmune hemolytic anemia and aplastic anemia have been reported in the treatment of patients with BCLL, as well as other disorders, generally at higher and more frequent doses than recommended in MS.
Use CBC results to monitor for cytopenias. Prompt medical intervention is indicated if a cytopenia is confirmed.
InfectionsInfections occurred in 71% of LEMTRADA-treated patients compared to 53% of patients treated with interferon beta-1a in controlled clinical studies in MS up to 2 years in duration. Infections that occurred more often in LEMTRADA-treated patients than interferon beta-1a patients included nasopharyngitis, urinary tract infection, upper respiratory tract infection, sinusitis, herpetic infections, influenza, and bronchitis. Serious infections occurred in 3% of patients treated with LEMTRADA as compared to 1% of patients treated with interferon beta-1a. Serious infections in the LEMTRADA group included: appendicitis, gastroenteritis, pneumonia, herpes zoster, and tooth infection.
Do not administer live viral vaccines following a course of LEMTRADA. Patients treated with LEMTRADA have altered immunity and may be at increased risk of infection following administration of live viral vaccines.
Consider delaying LEMTRADA administration in patients with active infection until the infection is fully controlled.
Concomitant use of LEMTRADA with antineoplastic or immunosuppressive therapies could increase the risk of immunosuppression.
Herpes Viral InfectionsIn controlled clinical studies, 16% of LEMTRADA-treated patients developed a herpes viral infectioncompared to 3% of interferon beta-1a patients. These events included oral herpes (8.8%), herpes zoster (4.2%), herpes simplex (1.8%), and genital herpes (1.3%). Serious herpetic infections in LEMTRADA-treated patients included primary varicella (0.1%), herpes zoster (0.2%), and herpes meningitis (0.1%). Administer antiviral agents for herpetic prophylaxis at appropriate suppressive dosing regimens. Administer antiviral prophylaxis for herpetic viral infections starting on the first day of each treatment course and continue for a minimum of two months following treatment with LEMTRADA or until the CD4+ lymphocyte count is ≥200 cells per microliter, whichever occurs later [see DOSAGE AND ADMINISTRATION].
Human Papilloma VirusCervical human papilloma virus (HPV) infection, including cervical dysplasia, occurred in 2% of LEMTRADA-treated patients. Annual HPV screening is recommended for female patients.
TuberculosisTuberculosis occurred in patients treated with LEMTRADA and interferon beta-1a in controlled clinical studies. Active and latent tuberculosis cases occurred in 0.3% of LEMTRADA-treated patients, most often in endemic regions. Perform tuberculosis screening according to local guidelines prior to initiation of LEMTRADA. For patients testing positive in tuberculosis screening, treat by standard medical practice prior to therapy with LEMTRADA.
Fungal InfectionsFungal infections, especially oral and vaginal candidiasis, occurred more commonly in LEMTRADA-treated patients (12%) than in patients treated with interferon beta-1a (3%) in controlled clinical studies in MS.
Listeria Monocytogenes InfectionsListeria monocytogenes infections (e.g., meningitis, encephalitis, sepsis, and gastroenteritis), including fatal cases of Listeria meningoencephalitis, have occurred in LEMTRADA-treated patients. Listeria infections have occurred as early as 3 days after treatment and up to 8 months after the last LEMTRADA dose. The duration of increased risk for Listeria infection after LEMTRADA treatment is unknown.
Advise patients to avoid or adequately heat foods that are potential sources of Listeria monocytogenes (e.g., deli meat, dairy products made with unpasteurized milk, soft cheeses, or undercooked meat, seafood, or poultry). Initiate these Listeria precautions prior to starting LEMTRADA treatment. The incubation period for Listeria monocytogenes ranges from 3 to 70 days. In most cases, signs and symptoms of invasive listeriosis start within 1 month of exposure to Listeria monocytogenes. Symptoms of Listeria infection include fever, chills, diarrhea, nausea, vomiting, headache, pains in joints and muscles, neck stiffness, difficulty walking, mental status changes, coma, and other neurologic changes. As is the case with many infections, treatment cannot always prevent mortality and morbidity related to Listeria infections. Therefore, advise patients to watch for symptoms of Listeria infection and seek prompt medical help if symptoms occur.
Infections In Non-MS PatientsDuring postmarketing use, serious and sometimes fatal viral, bacterial, protozoan, and fungal infections, including some due to reactivation of latent infections, have been reported in the treatment of patients with B-CLL, as well as other disorders, generally at higher and more frequent doses than recommended in MS.
HepatitisNo data are available on the association of LEMTRADA with Hepatitis B virus (HBV) or Hepatitis C virus (HCV) reactivation because patients with evidence of active or chronic infections were excluded from the clinical studies. Consider screening patients at high risk of HBV and/or HCV infection before initiation of LEMTRADA and exercise caution in prescribing LEMTRADA to patients identified as carriers of HBV and/or HCV as these patients may be at risk of irreversible liver damage relative to a potential virus reactivation as a consequence of their pre-existing status.
Acute Acalculous CholecystitisLEMTRADA may increase the risk of acute acalculous cholecystitis. In controlled clinical studies, 0.2% of LEMTRADA-treated MS patients developed acute acalculous cholecystitis, compared to 0% of patients treated with interferon beta-1a. During postmarketing use, additional cases of acute acalculous cholecystitis have been reported in LEMTRADA-treated patients. Time to onset of symptoms ranged from less than 24 hours to 2 months after LEMTRADA infusion. Typical risk or predisposing factors such as concurrent critical illness were often not reported. Abnormal ultrasound or computed tomography was used to support the diagnosis of acute acalculous cholecystitis in some cases. Some patients were treated conservatively with antibiotics and recovered without surgical intervention, whereas others underwent cholecystectomy.
Symptoms of acute acalculous cholecystitis include abdominal pain, abdominal tenderness, fever, nausea, and vomiting. Leukocytosis and abnormal liver enzymes are also commonly observed. Acute acalculous cholecystitis is a condition that is associated with high morbidity and mortality rates if not diagnosed early and treated. If acute acalculous cholecystitis is suspected, evaluate and treat promptly.
PneumonitisIn clinical studies, 6 of 1217 (0.5%) LEMTRADA-treated patients had pneumonitis of varying severity. Cases of hypersensitivity pneumonitis and pneumonitis with fibrosis occurred in clinical studies. Patients should be advised to report symptoms of pneumonitis, which include shortness of breath, cough, wheezing, chest pain or tightness, and hemoptysis.
Drug Products With Same Active IngredientLEMTRADA contains the same active ingredient (alemtuzumab) found in CAMPATH®. If LEMTRADA is considered for use in a patient who has previously received CAMPATH, exercise increased vigilance for additive and long-lasting effects on the immune system.
Patient Counseling InformationAdvise the patient to read the FDA-approved patient labeling (Medication Guide).
Autoimmunity· Advise patients to contact their healthcare provider promptly if they experience any symptoms of potential autoimmune disease. Give examples of important symptoms such as bleeding, easy bruising, petechiae, purpura, hematuria, edema, jaundice, or hemoptysis [see WARNINGS AND PRECAUTIONS].
· Advise patients of the importance of monthly blood and urine tests for 48 months following the last course of LEMTRADA to monitor for signs of autoimmunity because early detection and prompt treatment can help prevent serious and potentially fatal outcomes associated with these events. Advise patients that monitoring may need to continue past 48 months if they have signs or symptoms of autoimmunity.
· Advise patients that LEMTRADA may cause hyperthyroid or hypothyroid disorders.
· Advise patients to contact their healthcare provider if they experience symptoms reflective of a potential thyroid disorder such as unexplained weight loss or gain, fast heartbeat or palpitations, eye swelling, constipation, or feeling cold.
· Advise women of childbearing potential of the risks of pregnancy with concomitant thyroid disease. Advise women of childbearing potential to discuss pregnancy planning with their doctor.
Infusion Reactions· Advise patients that infusion reactions can occur after they leave the infusion center [see WARNINGS AND PRECAUTIONS].
· Instruct the patient to remain at the infusion center for 2 hours after each LEMTRADA infusion, or longer at the discretion of the physician. Advise patients that symptoms of infusion reactions may occur after they leave the infusion center and to report these symptoms to their doctor.
· Advise patients to contact their healthcare provider promptly if they experience infusion reactions, which include swelling in the mouth or throat, difficulty breathing, weakness, abnormal heart rate (fast, slow, or irregular), chest pain, and rash.
Malignancies· Advise patients that LEMTRADA may increase their risk of malignancies including thyroid cancer and melanoma [see WARNINGS AND PRECAUTIONS].
· Advise patients to report symptoms of thyroid cancer, including a new lump or swelling in the neck, pain in the front of the neck, hoarseness or other voice changes that do not go away, trouble swallowing or breathing, or a constant cough not due to a cold.
· Advise patients that they should have baseline and yearly skin examinations.
LEMTRADA REMS Program· LEMTRADA is available only through a restricted program called the LEMTRADA REMS Program [see WARNINGS AND PRECAUTIONS]. Inform the patient of the following notable requirements:
o Patients and providers must be enrolled in the program.
o Patients must comply with the ongoing monitoring requirements.
o Patients must report any side effects or symptoms to their doctor.
· LEMTRADA is available only at certified infusion centers participating in the program. Therefore, provide patients with information on the LEMTRADA REMS Program in order to locate an infusion center.
· Advise patients to read the LEMTRADA REMS material for patients, What You Need to Know About LEMTRADA Treatment: A Patient Guide and What You Need to Know About LEMTRADA Treatment and Infusion Reactions: A Patient Guide.
· Instruct patients to carry the LEMTRADA REMS Patient Safety Information Card with them in case of an emergency.
Infections· Advise patients to contact their healthcare provider if they develop symptoms of serious infection such as fever or swollen glands [see WARNINGS AND PRECAUTIONS].
· Advise patients to complete any necessary immunizations at least 6 weeks prior to treatment with LEMTRADA [see DOSAGE AND ADMINISTRATION]. Advise patients that they should talk to their healthcare provider before taking any vaccine after recent treatment with LEMTRADA [see WARNINGS AND PRECAUTIONS].
· Advise patients to take their prescribed medication for herpes prophylaxis as directed by their healthcare provider [see WARNINGS AND PRECAUTIONS].
· Advise patients that yearly HPV screening is recommended [see WARNINGS AND PRECAUTIONS].
· Advise patients to avoid or adequately heat foods that are potential sources of Listeriamonocytogenes prior to receiving LEMTRADA and if they have had a recent course of LEMTRADA. The duration of increased risk for Listeria infection after LEMTRADA administration is not known. Inform patients that Listeria infection can lead to significant complications or death. [see WARNINGS AND PRECAUTIONS].
Acute Acalculous Cholecystitis· Advise patients to report symptoms of acute acalculous cholecystitis. These include abdominal pain, abdominal tenderness, fever, nausea, and vomiting [see WARNINGS AND PRECAUTIONS]
Pneumonitis· Advise patients that pneumonitis has been reported in patients treated with LEMTRADA [seeWARNINGS AND PRECAUTIONS]. Advise patients to report symptoms of lung disease such as shortness of breath, cough, wheezing, chest pain or tightness, and hemoptysis.
Concomitant Use Of Campath· Advise patients that alemtuzumab is the same drug as Campath for use in B-CLL. Patients should inform their healthcare provider if they have taken Campath [see WARNINGS AND PRECAUTIONS].
Nonclinical ToxicologyCarcinogenesis, Mutagenesis, Impairment Of FertilityStudies to assess the carcinogenic or genotoxic potential of LEMTRADA have not been conducted.
When LEMTRADA (3 or 10 mg/kg IV) was administered to huCD52 transgenic male mice on 5 consecutive days prior to cohabitation with untreated wild-type females, no effect on fertility or reproductive performance was observed. However, adverse effects on sperm parameters (including abnormal morphology [detached /no head] and reduced total count and motility) were observed at both doses tested.
When LEMTRADA (3 or 10 mg/kg IV) was administered to huCD52 transgenic female mice for 5 consecutive days prior to cohabitation with untreated wild-type males, there was a decrease in the average number of corpora lutea and implantation sites and an increase in post-implantation loss, resulting in fewer viable embryos at the higher dose tested.
Use In Specific PopulationsPregnancyPregnancy Category CThere are no adequate and well-controlled studies in pregnant women. LEMTRADA was embryolethal in pregnant huCD52 transgenic mice when administered during organogenesis. Auto-antibodies may develop after administration of LEMTRADA. Placental transfer of antithyroid antibodies resulting in neonatal Graves' disease has been reported. LEMTRADA should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Animal DataWhen LEMTRADA was administered to pregnant huCD52 transgenic mice during organogenesis (gestation days [GD] 6-10 or GD 11-15) at doses of 3 or 10 mg/kg IV, no teratogenic effects were observed. However, there was an increase in embryolethality (increased post-implantation loss and the number of dams with all fetuses dead or resorbed) in pregnant animals dosed during GD 11-15.
In a separate study in pregnant huCD52 transgenic mice, administration of LEMTRADA during organogenesis (GD 6-10 or GD 11-15) at doses of 3 or 10 mg/kg/IV, decreases in B lymphocytes and T-lymphocyte populations were observed in the offspring at both doses tested. The effects of LEMTRADA, administered during organogenesis, on postnatal development have not been adequately assessed.
Clinical ConsiderationsTo avoid in utero exposure to LEMTRADA, women of child bearing potential should use effective contraceptive measures when receiving a course of treatment with LEMTRADA and for 4 months following that course of treatment.
LEMTRADA induces persistent thyroid disorders [see WARNINGS AND PRECAUTIONS]. Untreated hypothyroidism in pregnant women increases the risk for miscarriage and may have effects on the fetus including mental retardation and dwarfism. In mothers with Graves' disease, maternal thyroid stimulating hormone receptor antibodies can be transferred to a developing fetus and can cause neonatal Graves' disease. In a patient who developed Graves' disease after treatment with alemtuzumab, placental transfer of anti-thyrotropin receptor antibodies resulted in neonatal Graves' Disease with thyroid storm in her infant who was born 1 year after alemtuzumab dosing [see WARNINGS AND PRECAUTIONS].
Nursing MothersAlemtuzumab was detected in the milk of lactating mice administered 10 mg/kg LEMTRADA on Days 8 through 12 postpartum. Serum levels of alemtuzumab were similar in lactating mice and offspring on Day 13 postpartum, and were associated with evidence of pharmacological activity (decrease in lymphocyte counts) in the offspring.
It is not known whether alemtuzumab is excreted in human milk. Because many drugs are excreted in human milk, and because of the potential for serious adverse reactions in nursing infants from LEMTRADA, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
Pediatric UseSafety and effectiveness in pediatric patients less than 17 years of age have not been established. Use of LEMTRADA is not recommended in pediatric patients due to the risks of autoimmunity, infusion reactions, and because it may increase the risk of malignancies (thyroid, melanoma, lymphoproliferative disorders, and lymphoma) [see WARNINGS AND PRECAUTIONS].
Geriatric UseClinical studies of LEMTRADA did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently than younger patients.
Overdosage & Contraindications
OVERDOSETwo MS patients experienced serious reactions (headache, rash, and either hypotension or sinus tachycardia) after a single accidental infusion up to 60 mg of LEMTRADA. Doses of LEMTRADA greater than those recommended may increase the intensity and/or duration of infusion reactions or its immune effects. There is no known antidote for alemtuzumab overdosage.
CONTRAINDICATIONSLEMTRADA is contraindicated in patients who are infected with Human Immunodeficiency Virus(HIV) because LEMTRADA causes prolonged reductions of CD4+ lymphocyte counts.
Clinical Pharmacology
CLINICAL PHARMACOLOGYMechanism Of ActionThe precise mechanism by which alemtuzumab exerts its therapeutic effects in multiple sclerosis is unknown but is presumed to involve binding to CD52, a cell surface antigen present on T and B lymphocytes, and on natural killer cells, monocytes, and macrophages. Following cell surface binding to T and B lymphocytes, alemtuzumab results in antibody-dependent cellular cytolysis and complement-mediated lysis.
PharmacodynamicsEffects Of LEMTRADA On The Lymphocyte PopulationLEMTRADA depletes circulating T and B lymphocytes after each treatment course. In clinical trials, the lowest cell counts occurred 1 month after a course of treatment at the time of the first post-treatment blood count. Lymphocyte counts then increased over time: B cell counts usually recovered within 6 months; T cell counts increased more slowly and usually remained below baseline 12 months after treatment. Approximately 60% of patients had total lymphocyte counts below the lower limit of normal 6 months after each treatment course and 20% had counts below the lower limit of normal after 12 months.
Reconstitution of the lymphocyte population varies for the different lymphocyte subtypes. At Month 1 in clinical trials, the mean CD4+ lymphocyte count was 40 cells per microliter, and, at Month 12, 270 cells per microliter. At 30 months, approximately half of patients had CD4+ lymphocyte counts that remained below the lower limit of normal.
Cardiac ElectrophysiologyIn a study of 53 MS patients, alemtuzumab 12 mg per day for 5 days caused no changes in the QTc interval greater than 20 ms. An average 22 to 26 beats-per-minute increase in heart rate was observed for at least 2 hours after the first but not subsequent infusions.
PharmacokineticsThe pharmacokinetics of LEMTRADA were evaluated in a total of 148 patients with relapsing forms of MS who received 12 mg/day on 5 consecutive days, followed by 12 mg/day on 3 consecutive days 12 months following the first treatment course.
AbsorptionSerum concentrations increased with each consecutive dose within a treatment course, with the highest observed concentrations occurring following the last infusion of a treatment course. The mean maximum concentration was 3014 ng/mL on Day 5 of the first treatment course, and 2276 ng/mL on Day 3 of the second treatment course.
DistributionLEMTRADA is largely confined to the blood and interstitial space with a central volume of distribution of 14.1 L.
EliminationThe elimination half-life was approximately 2 weeks and was comparable between courses. The serum concentrations were generally undetectable (<60 ng/mL) within approximately 30 days following each treatment course.
Specific PopulationsAge, race, or gender had no effect on the pharmacokinetics of LEMTRADA.
Clinical StudiesThe efficacy of LEMTRADA was demonstrated in two studies (Study 1 and 2) that evaluated LEMTRADA 12 mg in patients with relapsing-remitting multiple sclerosis (RRMS). LEMTRADA was administered by intravenous infusion once daily over a 5-day course, followed one year later by intravenous infusion once daily over a 3-day course. Both studies included patients who had experienced at least 2 relapses during the 2 years prior to trial entry and at least 1 relapse during the year prior to trial entry. Neurological examinations were performed every 12 weeks and at the time of suspected relapse. Magnetic resonance imaging (MRI) evaluations were performed annually.
Study 1Study 1 was a 2 year randomized, open-label, rater-blinded, active comparator (interferon beta1a 44 micrograms administered subcutaneously three times a week) controlled study in patients with RRMS. Patients entering Study 1 had Expanded Disability Status Scale (EDSS) scores of 5 or less and had to have experienced at least one relapse while on interferon beta or glatiramer acetate therapy.
Patients were randomized to receive LEMTRADA (n=426) or interferon beta-1a (n=202). At baseline, the mean age was 35 years, the mean disease duration was 4.5 years, and the mean EDSS score was 2.7.
The clinical outcome measures were the annualized relapse rate (ARR) over 2 years and the time to confirmed disability progression. Confirmed disability progression was defined as at least a 1 point increase above baseline EDSS (1.5 point increase for patients with baseline EDSS of 0) sustained for 6 months. The MRI outcome measure was the change in T2 lesion volume.
The annualized relapse rate was significantly lower in patients treated with LEMTRADA than in patients who received interferon beta-1a. Time to onset of 6-month confirmed disability progression was significantly delayed with LEMTRADA treatment compared to interferon beta1a. There was no significant difference between the treatment groups for the change in T2 lesion volume. The results of Study 1 are shown in Table 2 and Figure 1.

Study 2 was a 2-year randomized, open-label, rater-blinded, active comparator (interferon beta1a 44 micrograms administered subcutaneously three times a week) controlled study in patients with RRMS. Patients entering Study 2 had EDSS scores of 3 or less and no prior treatment for multiple sclerosis.
Patients were randomized to receive LEMTRADA (n=376) or interferon beta-1a (n=187). At baseline, the mean age was 33 years, the mean disease duration was 2 years, and the mean EDSS score was 2.
The clinical outcome measures were the annualized relapse rate (ARR) over 2 years and the time to confirmed disability progression, as defined in Study 1. The MRI outcome measure was the change in T2 lesion volume.
The annualized relapse rate was significantly lower in patients treated with LEMTRADA than in patients who received interferon beta-1a. There was no significant difference between the treatment groups for the time to confirmed disability progression and for the primary MRI endpoint (change in T2 lesion volume). The results for Study 2 are shown in Table 3.

Medication Guide
PATIENT INFORMATION
LEMTRADA®
(lem-TRA-da)
(alemtuzumab) Injection for Intravenous Infusion
Read this Medication Guide before you start receiving LEMTRADA and before you begin each treatment course. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or treatment.
What is the most important information I should know about LEMTRADA?
LEMTRADA can cause serious side effects, including:
1. Serious autoimmune problems. Some people receiving LEMTRADA develop a condition where the immune cells in your body attack other cells or organs in the body (autoimmunity) which can be serious and may cause death. Serious autoimmune problems may include:
· immune thrombocytopenic purpura (ITP). LEMTRADA may cause the number of platelets in your blood to be reduced (ITP). ITP can cause severe bleeding that, if not treated, may cause life-threatening problems. Call your healthcare provider right away if you have any of the following symptoms:
o easy bruising
o bleeding from a cut that is hard to stop
o heavier menstrual periods than normal
o bleeding from your gums or nose that is new or takes longer than usual to stop
o small, scattered spots on your skin that are red, pink, or purple
· kidney problems. LEMTRADA may cause a serious kidney problem, called anti-glomerularbasement membrane disease. If this happens and you do not get treated, anti-glomerular basement membrane disease can lead to severe kidney damage, kidney failure that needs dialysis, a kidney transplant, or death. Call your healthcare provider right away if you have any of the following symptoms:
o blood in the urine (red or tea-colored urine)
o swelling in your legs or feet
o coughing up blood
Side effects may happen while you receive LEMTRADA and for 4 years after you stop receiving LEMTRADA. Your healthcare provider will order blood and urine tests before you receive, while you are receiving, and every month for 4 years after you receive your last LEMTRADA infusion. You may need to continue these blood and urine tests after 4 years if you have any autoimmune signs or symptoms. The blood and urine tests will help your healthcare provider watch for signs and symptoms of serious autoimmune problems.
It is important to have your blood and urine tested, even if you are feeling well and do not have any symptoms from LEMTRADA and your multiple sclerosis. This may help your healthcare provider find any problems early and will increase your chances of getting better.
2. Serious infusion reactions. LEMTRADA can cause serious infusion reactions that may cause death. Serious infusion reactions may happen while you receive, or up to 24 hours or longer after you receive LEMTRADA.
You will receive your infusion at a healthcare facility with equipment and staff trained to manage infusion reactions. You will be watched while you receive and for 2 hours after you receive LEMTRADA. It is important that you stay at the infusion center for 2 hours after your infusion is finished or longer if your healthcare provider decides you need to stay longer. If a serious infusion reaction happens while you are receiving LEMTRADA, your infusion may be stopped.
Tell your healthcare provider right away if you have any of the following symptoms of a serious infusion reaction during the infusion, and after you have left the healthcare facility:
· swelling in your mouth or throat
· trouble breathing
· weakness
· fast, slow, or irregular heart beat
· chest pain
· rash
To lower your chances of getting a serious infusion reaction, your healthcare provider will give you a medicine called corticosteroids before your first 3 infusions of a treatment course. You may also be given other medicines before or after the infusion to try reduce your chances of these reactions or to treat them after they happen.
3. Certain cancers. Receiving LEMTRADA may increase your chance of getting some kinds of cancers, including thyroid cancer, skin cancer (melanoma), and blood cancers called lymphoproliferative disorders and lymphoma. Call your healthcare provider if you have the following symptoms that may be a sign of thyroid cancer:
· new lump
· trouble swallowing or breathing
· swelling in your neck
· cough that is not caused by a cold
· pain in the front of your neck
· hoarseness or other voice changes that do not go away
You should have your skin checked before you start receiving LEMTRADA and each year while you are receiving treatment to monitor symptoms of skin cancer.
Because of your risk of autoimmunity, infusion reactions and the risk of some kinds of cancers, LEMTRADA is only available through a restricted program called the LEMTRADA Risk Evaluation and Mitigation Strategy (REMS) Program. Call 1-855-676-6326 to enroll in the LEMTRADA REMS Program.
· You and your healthcare provider must be enrolled in the LEMTRADA REMS Program.
· LEMTRADA can only be given at a certified healthcare facility that participates in the LEMTRADA REMS Program. Your healthcare provider can give you information on how to find a certified healthcare facility.
· Read the LEMTRADA REMS “What You Need to Know About LEMTRADA Treatment: A Patient Guide” and “What you Need to Know About LEMTRADA Treatment and Infusion Reactions: A Patient Guide” after you are enrolled in the program.
· Carry your LEMTRADA REMS Patient Safety Information Card with you in case of an emergency.
