【完整处方资料】
1 适应证和用途
        TECFIDERA适用为有复发型多发性硬化症患者的治疗。
2 剂量和给药方法
2.1 给药资料
        TECFIDERA 的开始剂量是120 mg 1天2次口服。在7天后,剂量应增加至维持剂量240 mg 1天2次口服。应全和完整吞服TECFIDERA。TECFIDERA不应被粉碎或咀嚼和胶囊内容物不要被洒散在食物上。TECFIDERA可有或无食物 服用。与食物给予可能减少脸红的发生率[见临床药理学(12.3)]。
2.2 开始治疗前血检验
        建议开始治疗前得到最近的全细胞计数(CBC)(即,6个月内)以鉴定患者有预先存在低淋巴细胞计数。
3 剂型和规格
        可得到TECFIDERA以硬明胶缓释胶囊含120 mg或240 mg富马酸二甲酯。120 mg胶囊有绿色和白色体,在体上以黑墨水印有“BG-12 120 mg”。240 mg胶囊有绿帽和绿体,在体上以黑墨水印有“BG-12 240 mg”。
4 禁忌证
        无。
5 警告和注意事项
5.1 淋巴细胞减少
        TECFIDERA 可能减低淋巴细胞计数[见不良反应(6.1)]。在MS安慰剂对照试验中,用TECFIDERA治疗头1年期间淋巴细胞计数均数减低约30%和然后保持稳 定。停止TECFIDERA后四周,淋巴细胞计数均数增加但未恢复至基线。TECFIDERA患者6%和安慰剂患者<1%经受淋巴细胞计数 <0.5 × 109/L(低于正常限度0.91 × 109/L)。用TECFIDERA治疗患者或安慰剂感染的发生率分别(60%相比58%)和严重感染(2%相比2%)相似。在淋巴细胞计数 <0.8 × 109/L或0.5× 109/L患者中未观察到严重感染发生率增加。
        开始用TECFIDERA治疗前应得到最近的全细胞计数CBC(即,6个月内)。建议每年和当临床上指示时进行全细胞计数。有严重感染患者应考虑不用治疗直至感染(s)解决。未曾在有预先存在低淋巴细胞计数患者中研究TECFIDERA。
5.2 脸红
        TECFIDERA 可能致脸红(如,温热,发红,瘙痒,和/或烧灼感觉)。在临床试验中,TECFIDERA治疗患者40%经受脸红。脸红症状一般在开始TECFIDERA 治疗后立即开始和通常随时间改善或解决。在经受脸红的大多数患者,其严重程度为轻或中度。为脸红3%患者终止TECFIDERA和<1%有严重脸红 症状不危及生命但导致住院。与食物给予TECFIDERA可能减低脸红的发生率。
6 不良反应
        在使用说明书其他地方描述以下重要不良反应:淋巴细胞减少,脸红[见警告和注意事项(5.1,5.2)]。
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。
        对TECFIDERA最常见不良反应(发生率 ≥10%和超过安慰剂≥2%)是脸红,腹痛,腹泻,和恶心。
        在安慰剂-对照试验中不良反应
        在两项对照良好研究显示有效性,1529例患者接受TECFIDERA有总暴露2244人-年[见临床研究(14)]。
        下表是根据来自769例用TECFIDERA 240 mg 1天2次治疗患者和771例安慰剂-治疗患者安全性资料展示的不良反应。

胃肠道
        TECFIDERA 致GI事件(如,恶心,呕吐,腹泻,腹痛,和消化不良)。与安慰剂比较用TECFIDERA治疗患者治疗过程较早期(主要在1个月内)GI事件的发生率较 高和通常随时间减低。用TECFIDERA治疗患者4%由于胃肠道事件终止和安慰剂患者小于1%。用TECFIDERA治疗患者严重GI事件的发生率为 1%。
肝转氨酶
        用 TECFIDERA治疗患者见到肝转氨酶升高发生率增加,主要地在治疗的头6个月期间,和大多数患者有升高水平< 3倍正常上限(ULN)。小量用TECFIDERA和安慰剂二者治疗患者数发生丙氨酸氨基转移酶和天门冬氨酸氨基转移酶的升高至ULN的 ≥ 3倍和组间被平衡。无转氨酶升高 ≥ 3倍ULN同时有总胆红素 > 2倍ULN升高。由于肝转氨酶升高终止为 < 1%和用TECFIDERA治疗患者或安慰剂相似。
嗜酸性粒细胞增多
        治疗的头2个月期间见到嗜酸性计数均数的短暂增加。
        在安慰剂-对照和无对照研究的不良反应
        在 安慰剂-对照和无对照临床研究中,总共2513例患者曾接受TECFIDERA和倍随访为期直至4年有总暴露为4603例人-年。约1162例患者曾接受 用TECFIDERA治疗超过2年。在无对照临床研究TECFIDERA的不良反应图形与安慰剂-对照临床试验经验一致。
8 特殊人群中使用
8.1 妊娠
        妊娠类别C
        在妊娠妇女没有适当和对照良好研究。在动物中,当妊娠和哺乳期间给予富马酸二甲酯(DMF)临床上相关剂量观察到对子代活存,生长,性成熟,和神经行为功能不良影响。妊娠期间只有如果潜在获益被证明胜过对胎儿潜在风险,才应使用TECFIDERA。
        在 大鼠中在器官形成期自始至终给予口服DMF(25,100,250 mg/kg/day),在最高受试剂量观察到胚胎胎鼠毒性(减低胎鼠体重和延迟)。这个剂量还产生母体毒性的证据(体重减轻)。在无-效应剂量对富马酸单 甲酯(MMF),主要循环代谢物的血浆暴露(AUC),约为人中推荐人剂量时(RHD)480 mg/day时暴露的3倍。在兔中器官形成期自始至终给予DMF口服(25,75,和150 mg/kg/day),在最高受试剂量观察到胚胎死亡和母体体重减轻。在无-效应剂量时对富马酸单甲酯(MMF)血浆AUC约为人中RHD时的5倍。
        大 鼠器官形成期和哺乳期自始至终口服给予DMF(25,100,and 250 mg/kg/day),导致增加致死率,持久减轻体重,延迟性成熟(雄性和雌性幼崽),而在最高受试剂量时减低睾丸重量。所有剂量观察到神经行为损伤。未 确定对发育毒性的无效应剂量。最低受试剂量伴有血浆富马酸单甲酯(MMF)AUC低于在人中在推荐剂量RHD的MMF的AUC。

8.3 哺乳母亲

        不知道此药是否排泄在人乳汁中。因为许多药物排泄在人乳汁,当TECFIDERA被给予哺乳妇女应谨慎对待。
8.4 儿童使用
        尚未确定在儿童患者中的安全性和有效性。
8.5 老年人使用
TECFIDERA的临床研究未包括足够数量年龄65和以上患者以确定他们的反应是否与较年轻患者不同。
11 一般描述
        TECFIDERA含富马酸二甲酯[dimethyl fumarate]它也通过其化学名已知,dimethyl (E) butenedioate,(C6H8O4)。
富马酸二甲酯是白色至灰白色粉高度溶于水分子质量144.13。
        为 口服给药TECFIDERA以硬明胶缓释胶囊提供,含120 mg或240 mg富马酸二甲酯由以下无活性成分组成:微晶纤维素,硅化微晶纤维素,交联羧甲基纤维素钠,滑石,硅胶二氧化硅,硬脂酸镁,柠檬酸三乙酯,甲基丙烯酸共聚 物- 型A,甲基丙烯酸共聚物分散液,二甲基硅油(30%乳胶),月桂基硫酸钠,和聚山梨醇80。胶囊壳,印用黑墨水,含以下无活性成分:明胶,二氧化 钛,FD&C 蓝1;亮蓝 FCF,铁黄氧化物和黑铁氧化物。
12 临床药理学
12.1 作用机制
        不知道富马酸二甲酯(DMF)在多发性硬化症中发挥其治疗作用的机制。DMF和代谢物,富马酸单甲酯(MMF),曾显示在动物和人中在体外和在体内激活核因 子[Nuclear factor](红系衍生2)-样2(Nrf2)通路。Nrf2通路涉及对氧化应激细胞反应。富马酸单甲酯曾被鉴定在体外为烟酸受体激动剂。
12.2 药效动力学
        延长QT间隔潜能
        在健康受试者中进行一项安慰剂对照彻底QT研究,没有证据表明富马酸二甲酯致QT间隔临床意义的延长(即,对最大的安慰剂-校正的,基线-校正的QTc90%可信区间的上限低于10 ms)。
12.3 药代动力学
        口服给予TECFIDERA后,富马酸二甲酯被酯酶迅速进行体循环前水解和被转化为其活性代谢物,富马酸单甲酯(MMF)。口服给予TECFIDERA后血浆中不能定量到富马酸二甲酯。因此所有与TECFIDERA相关的药代动力学分析是用血浆富马酸单甲酯(MMF)浓度进行的。
        在有多发性硬化症受试者和健康志愿者中得到药代动力学数据。
吸收
        富马酸单甲酯(MMF)的中位达峰时间Tmax是2-2.5小时。血浆峰浓度(Cmax)和总暴露(AUC)增加约 在被研究的剂量范围(120 mg至360 mg)与剂量成正比例。在MS患者中与食物给予TECFIDERA 240 mg 1天2次后,富马酸单甲酯(MMF)的均数Cmax为1.87 mg/L和AUC为8.21 mg.hr/L。
        一个高脂肪,高热量餐不影响富马酸单甲酯(MMF)的AUC但其Cmax减低40%。达峰时间Tmax被延后从2.0小时至5.5小时,在这项研究中,在进食状态脸红的发生率被减少约25%。
分布
        健康受试者中富马酸单甲酯(MMF)的表观分布容积变动在53和73 L间。富马酸单甲酯(MMF)的人血浆蛋白结合是27-45%和不依赖于浓度。
代谢
        在人中,在富马酸二甲酯到达循环前,富马酸二甲酯被胃肠道,血液和组织无处不在的酯酶广泛代谢。富马酸单甲酯(MMF)通过三羧酸(TCA)循环发生进一步 代谢,不涉及到细胞色素P450 (CYP) 系统。富马酸单甲酯(MMF),富马酸和柠檬酸,和葡萄糖是血浆中主要代谢物。
消除
        呼出CO2的主要途径消除,约占TECFIDERA剂量的60%。肾和粪消除是次要消除途径,分别占剂量的16%和1%。尿中存在痕量未变化富马酸单甲酯(MMF)。
        富马酸单甲酯(MMF)的末端半衰期是约1小时和在大多数个体中在24小时不存在循环富马酸单甲酯(MMF)。在多剂量TECFIDERA后不发生富马酸单甲酯(MMF)的积蓄。
特殊人群
        无需对体重,性别,和年龄调整剂量。
        在肝或肾受损受试者中未曾进行研究。但是,预计两种情况都不影响对富马酸单甲酯(MMF)暴露和因此无需调整剂量。
药物相互作用研究
        在 体外CYP 抑制作用和诱导作用研究,或在P-糖蛋白研究未鉴定到与富马酸二甲酯或富马酸单甲酯(MMF) 潜在药物相互作用。单剂量的干扰素β-1a或醋酸格拉替雷[glatiramer acetate]均不改变富马酸单甲酯(MMF)的药代动力学。阿司匹林[Aspirin],当在TECFIDERA前30分钟给予,不改变富马酸单甲酯 (MMF)的药代动力学。
13 非临床毒理学
13.1 癌发生,突变发生,生育能力受损
癌发生
        在小鼠和大鼠中进行富马酸二甲酯(DMF)的致癌性研究。在小鼠中,口服给予DMF (25,75,200,和400 mg/kg/day)直至2年导致在非腺体胃部分(前胃)和肾脏肿瘤增加:鳞状细胞癌和雄性和雌性在200和400 mg/kg/day时前胃的导管内乳头状瘤;在雄性和雌性400 mg/kg/day时前胃平滑肌肉瘤;  在雄性200和400 mg/kg/day时肾小管腺瘤和癌;和在雌性400 mg/kg/day时肾小管腺瘤。在小鼠不伴随肿瘤最高剂量为(75 mg/kg/day),血浆富马酸单甲酯(MMF)暴露(AUC)相似于人中在推荐人用剂量(RHD) 480 mg/day。
        在大鼠中,口服给 予DMF (25,50,100,和150 mg/kg/day)直至2年,在雄性和雌性所有受试剂量导致前胃鳞状细胞癌和导管内乳头状瘤增加和在100和150 mg/kg/day剂量 in 睾丸间质(Leydig)细胞腺瘤。在最低受试剂量血浆富马酸单甲酯(MMF) AUC是低于人中在推荐人用剂量RHD。
突变发生
        在体外细菌回复突变(Ames)试验中富马酸二甲酯(DMF)和富马酸单甲酯(MMF)不是致突变剂。. 在体外外周血淋巴细胞在缺乏代谢活化时染色体畸变试验DMF和富马酸单甲酯(MMF)是致染色体断裂。大鼠体内微核试验DMF不是致畸剂。
生育能力受损
        在雄性大鼠中交配期前和自始至终,口服给予DMF (75,250,和375 mg/kg/day)对生育能力没有影响;但是,在中和高剂量观察到不-活动精子增加。对精子无不良作用剂量在体表面积(mg/m2)基础对相似于推荐人剂量(RHD) 480 mg/day。
        在雌性大鼠中,在交配前和期间口服给予DMF(20,100,和 250 mg/kg/day)并继续至怀孕第7天致动情周期破坏和在最高受试剂量胚胎死亡增加。不伴有不良效应的最高剂量(100 mg/kg/day)在mg/m2基础是人RHD两倍。
        在小鼠,大鼠,和犬在DMF的亚慢性和大鼠中慢性口服毒性研究评价四种富马酸酯(包括DMF),在临床相关剂量观察到睾丸毒性(生发上皮变性,萎缩,精子减少症,和/或增生)。
13.2 动物毒理学和/或药理学
        在小鼠,大鼠,犬,和猴中重复口服给予富马酸二甲酯(DMF)观察到肾毒性。在所有物种观察到肾小管上皮细胞再生,提示肾小管上皮细胞损伤。大鼠给药至2年 观察到肾小管增生。在犬和猴在剂量高于5 mg/kg/day观察到皮质萎缩和小肠纤维化。在猴中,最高测试剂量(75 mg/kg/day)伴有单细胞坏死和多灶性和弥漫性小肠纤维化,表明肾组织和功能的不可逆损失。在犬和猴中, 5 mg/kg/day 剂量伴血浆富马酸单甲酯(MMF)暴露低于或相似于在人中在推荐人剂量时(RHD)暴露。
        在小鼠口服给予DMF在剂量75 mg/kg/day以上,一个剂量伴血浆富马酸单甲酯(MMF)暴露(AUC)相似于在人中在RHD时暴露直至2年后观察到视网膜变性发生率和的严重程度剂量相关增加。
14 临床研究
        在有复发缓解型多发性硬化症(RRMS)患者中两项研究(研究1和2)评价服用TECFIDERA或1天2或3次,证实TECFIDERA的疗效和安全性。 TECFIDERA的开始剂量对头7天为120 mg 1天2或3次,接着增加至240 mg 1天2或3次。两项研究包括试验前1年曾经受至少1次复发或随机化6周内大脑核磁共振影像(MRI)扫描证实至少1个钆增强(Gd+)病变患者。还评估扩 张残疾状态计分(EDSS)而患者能有计分范围0至5。在基线时,每3个月,和怀疑复发时进行神经学评价。在基线时, 6个月,和1和2年在患者子组(研究1为44%和研究2为48%)进行MRI评价。
研究1:复发缓解型多发性硬化症安慰剂-对照试验
        研究1是在1234例有复发缓解型多发性硬化症患者中一项2-年随机化,双盲,安慰剂-对照研究。主要终点是在2年时复发患者的比例。在2年时另外终点包括 新或新增大T2高信号病变数,新T1低信号病变数, Gd+病变数,年复发率(ARR),和至确认的残疾进展时间。确认的残疾进展被定义为从基线EDSS至少增加1点(对基线EDSS为0的患者增加1.5 点)持续12周。患者被随机化接受TECFIDERA 240 mg 1天2次(n=410),TECFIDERA 240 mg 1天3次(n=416),或安慰剂 (n=408)达2年。中位年龄39岁,自诊断中位时间为4年,而在基线时中位EDSS计分为2。用研究药物对治疗组中位时间为96周。对被赋予 TECFIDERA 240 mg 1天2次患者,用研究药物完成96周每治疗组患者的百分率为69%, 对被赋予TECFIDERA 240 mg 1天3次患者为69%而对被赋予安慰剂组患者为65%。
        TECFIDERA对所有上述终点都有统计显著影响和240 mg每天3次给药未显示超出TECFIDERA 240 mg每天2次给药的增加获益。表2和图1显示本研究(240 mg 1天2次相比安慰剂)的结果。

Tecfidera

Generic Name: dimethyl fumarate
Dosage Form: capsules

Medically reviewed on Jun 1, 2018

 

Indications and Usage for Tecfidera

See also: Aubagio

Tecfidera is indicated for the treatment of patients with relapsing forms of multiple sclerosis.

Tecfidera Dosage and AdministrationDosing Information

The starting dose for Tecfidera is 120 mg twice a day orally. After 7 days, the dose should be increased to the maintenance dose of 240 mg twice a day orally. Temporary dose reductions to 120 mg twice a day may be considered for individuals who do not tolerate the maintenance dose. Within 4 weeks, the recommended dose of 240 mg twice a day should be resumed. Discontinuation of Tecfidera should be considered for patients unable to tolerate return to the maintenance dose. The incidence of flushing may be reduced by administration of Tecfidera with food. Alternatively, administration of non-enteric coated aspirin (up to a dose of 325 mg) 30 minutes prior to Tecfidera dosing may reduce the incidence or severity of flushing [see Clinical Pharmacology (12.3)].

Tecfidera should be swallowed whole and intact. Tecfidera should not be crushed or chewed and the capsule contents should not be sprinkled on food. Tecfidera can be taken with or without food.

Blood Tests Prior to Initiation of Therapy

Obtain a complete blood cell count (CBC) including lymphocyte count before initiation of therapy [see Warnings and Precautions (5.3)].

Obtain serum aminotransferase, alkaline phosphatase, and total bilirubin levels prior to treatment with Tecfidera [see Warnings and Precautions (5.4)].

Dosage Forms and Strengths

Tecfidera is available as hard gelatin delayed-release capsules containing 120 mg or 240 mg of dimethyl fumarate. The 120 mg capsules have a green cap and white body, printed with “BG-12 120 mg” in black ink on the body. The 240 mg capsules have a green cap and a green body, printed with “BG-12 240 mg” in black ink on the body.

Contraindications

Tecfidera is contraindicated in patients with known hypersensitivity to dimethyl fumarate or to any of the excipients of Tecfidera. Reactions have included anaphylaxis and angioedema [see Warnings and Precautions (5.1)].

Warnings and PrecautionsAnaphylaxis and Angioedema

Tecfidera can cause anaphylaxis and angioedema after the first dose or at any time during treatment. Signs and symptoms have included difficulty breathing, urticaria, and swelling of the throat and tongue. Patients should be instructed to discontinue Tecfidera and seek immediate medical care should they experience signs and symptoms of anaphylaxis or angioedema.

Progressive Multifocal Leukoencephalopathy

Progressive multifocal leukoencephalopathy (PML) has occurred in patients with MS treated with Tecfidera. PML is an opportunistic viral infection of the brain caused by the JC virus (JCV) that typically only occurs in patients who are immunocompromised, and that usually leads to death or severe disability. A fatal case of PML occurred in a patient who received Tecfidera for 4 years while enrolled in a clinical trial. During the clinical trial, the patient experienced prolonged lymphopenia (lymphocyte counts predominantly <0.5x109/L for 3.5 years) while taking Tecfidera [see Warnings and Precautions (5.3)]. The patient had no other identified systemic medical conditions resulting in compromised immune system function and had not previously been treated with natalizumab, which has a known association with PML. The patient was also not taking any immunosuppressive or immunomodulatory medications concomitantly.

PML has also occurred in the postmarketing setting in the presence of lymphopenia (<0.8x109/L) persisting for more than 6 months. While the role of lymphopenia in these cases is uncertain, the majority of cases occurred in patients with lymphocyte counts <0.5x 109/L.

At the first sign or symptom suggestive of PML, withhold Tecfidera and perform an appropriate diagnostic evaluation. Typical symptoms associated with PML are diverse, progress over days to weeks, and include progressive weakness on one side of the body or clumsiness of limbs, disturbance of vision, and changes in thinking, memory, and orientation leading to confusion and personality changes.

MRI findings may be apparent before clinical signs or symptoms. Cases of PML, diagnosed based on MRI findings and the detection of JCV DNA in the cerebrospinal fluid in the absence of clinical signs or symptoms specific to PML, have been reported in patients treated with other MS medications associated with PML. Many of these patients subsequently became symptomatic with PML. Therefore, monitoring with MRI for signs that may be consistent with PML may be useful, and any suspicious findings should lead to further investigation to allow for an early diagnosis of PML, if present. Lower PML-related mortality and morbidity have been reported following discontinuation of another MS medication associated with PML in patients with PML who were initially asymptomatic compared to patients with PML who had characteristic clinical signs and symptoms at diagnosis. It is not known whether these differences are due to early detection and discontinuation of MS treatment or due to differences in disease in these patients.

Lymphopenia

Tecfidera may decrease lymphocyte counts. In the MS placebo controlled trials, mean lymphocyte counts decreased by approximately 30% during the first year of treatment with Tecfidera and then remained stable. Four weeks after stopping Tecfidera, mean lymphocyte counts increased but did not return to baseline. Six percent (6%) of Tecfidera patients and <1% of placebo patients experienced lymphocyte counts <0.5x109/L (lower limit of normal 0.91x109/L). The incidence of infections (60% vs 58%) and serious infections (2% vs 2%) was similar in patients treated with Tecfidera or placebo, respectively. There was no increased incidence of serious infections observed in patients with lymphocyte counts <0.8x109/L or ≤0.5x109/L in controlled trials, although one patient in an extension study developed PML in the setting of prolonged lymphopenia (lymphocyte counts predominantly <0.5x109/L for 3.5 years) [see Warnings and Precautions (5.2)].

In controlled and uncontrolled clinical trials, 2% of patients experienced lymphocyte counts <0.5 x 109/L for at least six months, and in this group the majority of lymphocyte counts remained <0.5x109/L with continued therapy. Tecfidera has not been studied in patients with pre-existing low lymphocyte counts.

Obtain a CBC, including lymphocyte count, before initiating treatment with Tecfidera, 6 months after starting treatment, and then every 6 to 12 months thereafter, and as clinically indicated. Consider interruption of Tecfidera in patients with lymphocyte counts less than 0.5 x 109/L persisting for more than six months. Given the potential for delayed recovery of lymphocyte counts, continue to obtain lymphocyte counts until their recovery if Tecfidera is discontinued or interrupted due to lymphopenia. Consider withholding treatment from patients with serious infections until resolution. Decisions about whether or not to restart Tecfidera should be individualized based on clinical circumstances.

5.4 Liver Injury

Clinically significant cases of liver injury have been reported in patients treated with Tecfidera in the postmarketing setting. The onset has ranged from a few days to several months after initiation of treatment with Tecfidera. Signs and symptoms of liver injury, including elevation of serum aminotransferases to greater than 5-fold the upper limit of normal and elevation of total bilirubin to greater than 2-fold the upper limit of normal have been observed. These abnormalities resolved upon treatment discontinuation. Some cases required hospitalization. None of the reported cases resulted in liver failure, liver transplant, or death. However, the combination of new serum aminotransferase elevations with increased levels of bilirubin caused by drug-induced hepatocellular injury is an important predictor of serious liver injury that may lead to acute liver failure, liver transplant, or death in some patients.

Elevations of hepatic transaminases (most no greater than 3 times the upper limit of normal) were observed during controlled trials [see Adverse Reactions (6.1)].

Obtain serum aminotransferase, alkaline phosphatase (ALP), and total bilirubin levels prior to treatment with Tecfidera and during treatment, as clinically indicated. Discontinue Tecfidera if clinically significant liver injury induced by Tecfidera is suspected.

Flushing

Tecfidera may cause flushing (e.g., warmth, redness, itching, and/or burning sensation). In clinical trials, 40% of Tecfidera treated patients experienced flushing. Flushing symptoms generally began soon after initiating Tecfidera and usually improved or resolved over time. In the majority of patients who experienced flushing, it was mild or moderate in severity. Three percent (3%) of patients discontinued Tecfidera for flushing and <1% had serious flushing symptoms that were not life-threatening but led to hospitalization. Administration of Tecfidera with food may reduce the incidence of flushing. Alternatively, administration of non-enteric coated aspirin (up to a dose of 325 mg) 30 minutes prior to Tecfidera dosing may reduce the incidence or severity of flushing [see Dosing and Administration (2.1) and Clinical Pharmacology (12.3)].

Adverse Reactions

The following important adverse reactions are described elsewhere in labeling:

· Anaphylaxis and Angioedema [see Warnings and Precautions (5.1)].

· Progressive multifocal leukoencephalopathy [see Warnings and Precautions (5.2)].

· Lymphopenia [see Warnings and Precautions (5.3)].

· Liver Injury [see Warnings and Precautions (5.4)].

· Flushing [see Warnings and Precautions (5.5)].

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

The most common adverse reactions (incidence ≥10% and ≥2% more than placebo) for Tecfidera were flushing, abdominal pain, diarrhea, and nausea.

Adverse Reactions in Placebo-Controlled Trials

In the two well-controlled studies demonstrating effectiveness, 1529 patients received Tecfidera with an overall exposure of 2244 person-years [see Clinical Studies (14)].

The adverse reactions presented in the table below are based on safety information from 769 patients treated with Tecfidera 240 mg twice a day and 771 placebo-treated patients.

Gastrointestinal

Tecfidera caused GI events (e.g., nausea, vomiting, diarrhea, abdominal pain, and dyspepsia). The incidence of GI events was higher early in the course of treatment (primarily in month 1) and usually decreased over time in patients treated with Tecfidera compared with placebo. Four percent (4%) of patients treated with Tecfidera and less than 1% of placebo patients discontinued due to gastrointestinal events. The incidence of serious GI events was 1% in patients treated with Tecfidera.

Hepatic Transaminases

An increased incidence of elevations of hepatic transaminases in patients treated with Tecfidera was seen primarily during the first six months of treatment, and most patients with elevations had levels < 3 times the upper limit of normal (ULN) during controlled trials. Elevations of alanine aminotransferase and aspartate aminotransferase to ≥ 3 times the ULN occurred in a small number of patients treated with both Tecfidera and placebo and were balanced between groups. There were no elevations in transaminases ≥ 3 times the ULN with concomitant elevations in total bilirubin > 2 times the ULN. Discontinuations due to elevated hepatic transaminases were < 1% and were similar in patients treated with Tecfidera or placebo.

Eosinophilia

A transient increase in mean eosinophil counts was seen during the first 2 months of therapy.

Adverse Reactions in Placebo-Controlled and Uncontrolled Studies

In placebo-controlled and uncontrolled clinical studies, a total of 2513 patients have received Tecfidera and been followed for periods up to 4 years with an overall exposure of 4603 person-years. Approximately 1162 patients have received more than 2 years of treatment with Tecfidera. The adverse reaction profile of Tecfidera in the uncontrolled clinical studies was consistent with the experience in the placebo-controlled clinical trials.

Post Marketing Experience

The following adverse reaction has been identified during post approval use of Tecfidera. 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.

Liver function abnormalities (elevations in transaminases ≥ 3 times ULN with concomitant elevations in total bilirubin > 2 times ULN) have been reported following Tecfidera administration in post marketing experience [See Warnings and Precautions (5.4)].

USE IN SPECIFIC POPULATIONSPregnancy

Pregnancy Exposure Registry

There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to Tecfidera during pregnancy. Encourage patients to enroll by calling 1-866-810-1462 or visiting www.Tecfiderapregnancyregistry.com.

Risk Summary

There are no adequate data on the developmental risk associated with the use of Tecfidera in pregnant women. In animals, adverse effects on offspring survival, growth, sexual maturation, and neurobehavioral function were observed when dimethyl fumarate (DMF) was administered during pregnancy and lactation at clinically relevant doses [see Data].

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. The background risk of major birth defects and miscarriage for the indicated population is unknown.

Data

Animal Data

In rats administered DMF orally (25, 100, 250 mg/kg/day) throughout organogenesis, embryofetal toxicity (reduced fetal body weight and delayed ossification) were observed at the highest dose tested. This dose also produced evidence of maternal toxicity (reduced body weight). Plasma exposure (AUC) for monomethyl fumarate (MMF), the major circulating metabolite, at the no-effect dose is approximately three times that in humans at the recommended human dose (RHD) of 480 mg/day. In rabbits administered DMF orally (25, 75, and 150 mg/kg/day) throughout organogenesis, embryolethality and decreased maternal body weight were observed at the highest dose tested. The plasma AUC for MMF at the no-effect dose is approximately 5 times that in humans at the RHD.

Oral administration of DMF (25, 100, and 250 mg/kg/day) to rats throughout organogenesis and lactation resulted in increased lethality, persistent reductions in body weight, delayed sexual maturation (male and female pups), and reduced testicular weight at the highest dose tested. Neurobehavioral impairment was observed at all doses. A no-effect dose for developmental toxicity was not identified. The lowest dose tested was associated with plasma AUC for MMF lower than that in humans at the RHD.

Lactation

Risk Summary

There are no data on the presence of DMF or MMF in human milk. The effects on the breastfed infant and on milk production are unknown.

The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Tecfidera and any potential adverse effects on the breastfed infant from the drug or from the underlying maternal condition.

Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

Geriatric Use

Clinical studies of Tecfidera did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients.

OVERDOSE

Cases of overdose with Tecfidera have been reported. The symptoms described in these cases were consistent with the known adverse event profile of Tecfidera.

There are no known therapeutic interventions to enhance elimination of Tecfidera nor is there a known antidote. In the event of overdose, initiate symptomatic supportive treatment as clinically indicated.

Tecfidera Description

Tecfidera contains dimethyl fumarate which is also known by its chemical name, dimethyl (E) butenedioate, (C6H8O4). It has the following structure:

from clipboard 

Dimethyl fumarate is a white to off-white powder that is highly soluble in water with a molecular mass of 144.13.

Tecfidera is provided as hard gelatin delayed-release capsules for oral administration, containing 120 mg or 240 mg of dimethyl fumarate consisting of the following inactive ingredients: microcrystalline cellulose, silicified microcrystalline cellulose, croscarmellose sodium, talc, silica colloidal silicon dioxide, magnesium stearate, triethyl citrate, methacrylic acid copolymer - Type A, methacrylic acid copolymer dispersion, simethicone (30% emulsion), sodium lauryl sulphate, and polysorbate 80. The capsule shell, printed with black ink, contains the following inactive ingredients: gelatin, titanium dioxide, FD&C blue 1; brilliant blue FCF, yellow iron oxide and black iron oxide.

Tecfidera - Clinical PharmacologyMechanism of Action

The mechanism by which dimethyl fumarate (DMF) exerts its therapeutic effect in multiple sclerosis is unknown. DMF and the metabolite, monomethyl fumarate (MMF), have been shown to activate the Nuclear factor (erythroid-derived 2)-like 2 (Nrf2) pathway in vitro and in vivo in animals and humans. The Nrf2 pathway is involved in the cellular response to oxidative stress. MMF has been identified as a nicotinic acid receptor agonist in vitro.

Pharmacodynamics

Potential to prolong the QT interval

In a placebo controlled thorough QT study performed in healthy subjects, there was no evidence that dimethyl fumarate caused QT interval prolongation of clinical significance (i.e., the upper bound of the 90% confidence interval for the largest placebo-adjusted, baseline-corrected QTc was below 10 ms).

Pharmacokinetics

After oral administration of Tecfidera, dimethyl fumarate undergoes rapid presystemic hydrolysis by esterases and is converted to its active metabolite, monomethyl fumarate (MMF). Dimethyl fumarate is not quantifiable in plasma following oral administration of Tecfidera. Therefore all pharmacokinetic analyses related to Tecfidera were performed with plasma MMF concentrations. Pharmacokinetic data were obtained in subjects with multiple sclerosis and healthy volunteers.

Absorption

The median Tmax of MMF is 2-2.5 hours. The peak plasma concentration (Cmax) and overall exposure (AUC) increased approximately dose proportionally in the dose range studied (120 mg to 360 mg). Following administration of Tecfidera 240 mg twice a day with food, the mean Cmax of MMF was 1.87 mg/L and AUC was 8.21 mg.hr/L in MS patients.

A high-fat, high-calorie meal did not affect the AUC of MMF but decreased its Cmax by 40%. The Tmax was delayed from 2.0 hours to 5.5 hours. In this study, the incidence of flushing was reduced by approximately 25% in the fed state.

Distribution

The apparent volume of distribution of MMF varies between 53 and 73 L in healthy subjects. Human plasma protein binding of MMF is 27-45% and independent of concentration.

Metabolism

In humans, dimethyl fumarate is extensively metabolized by esterases, which are ubiquitous in the gastrointestinal tract, blood, and tissues, before it reaches the systemic circulation. Further metabolism of MMF occurs through the tricarboxylic acid (TCA) cycle, with no involvement of the cytochrome P450 (CYP) system. MMF, fumaric and citric acid, and glucose are the major metabolites in plasma.

Elimination

Exhalation of CO2 is the primary route of elimination, accounting for approximately 60% of the Tecfidera dose. Renal and fecal elimination are minor routes of elimination, accounting for 16% and 1% of the dose respectively. Trace amounts of unchanged MMF were present in urine.

The terminal half-life of MMF is approximately 1 hour and no circulating MMF is present at 24 hours in the majority of individuals. Accumulation of MMF does not occur with multiple doses of Tecfidera.

Specific Populations

Body weight, gender, and age do not require dosage adjustment.

No studies have been conducted in subjects with hepatic or renal impairment. However, neither condition would be expected to affect exposure to MMF and therefore no dosage adjustment is necessary.

Drug Interaction Studies

No potential drug interactions with dimethyl fumarate or MMF were identified in in vitro CYP inhibition and induction studies, or in P-glycoprotein studies. Single doses of interferon beta-1a or glatiramer acetate did not alter the pharmacokinetics of MMF. Aspirin, when administered approximately 30 minutes before Tecfidera, did not alter the pharmacokinetics of MMF.

Oral Contraceptives

The coadministration of dimethyl fumarate with a combined oral contraceptive (norelgestromin and ethinyl estradiol) did not elicit any relevant effects in oral contraceptives exposure.  No interaction studies have been performed with oral contraceptives containing other progestogens.

Nonclinical ToxicologyCarcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenesis

Carcinogenicity studies of dimethyl fumarate (DMF) were conducted in mice and rats. In mice, oral administration of DMF (25, 75, 200, and 400 mg/kg/day) for up to two years resulted in an increase in nonglandular stomach (forestomach) and kidney tumors: squamous cell carcinomas and papillomas of the forestomach in males and females at 200 and 400 mg/kg/day; leiomyosarcomas of the forestomach at 400 mg/kg/day in males and females; renal tubular adenomas and carcinomas at 200 and 400 mg/kg/day in males; and renal tubule adenomas at 400 mg/kg/day in females. Plasma MMF exposure (AUC) at the highest dose not associated with tumors in mice (75 mg/kg/day) was similar to that in humans at the recommended human dose (RHD) of 480 mg/day.

In rats, oral administration of DMF (25, 50, 100, and 150 mg/kg/day) for up to two years resulted in increases in squamous cell carcinomas and papillomas of the forestomach at all doses tested in males and females, and in testicular interstitial (Leydig) cell adenomas at 100 and 150 mg/kg/day. Plasma MMF AUC at the lowest dose tested was lower than that in humans at the RHD.

Mutagenesis

Dimethyl fumarate (DMF) and monomethyl fumarate (MMF) were not mutagenic in the in vitro bacterial reverse mutation (Ames) assay. DMF and MMF were clastogenic in the in vitro chromosomal aberration assay in human peripheral blood lymphocytes in the absence of metabolic activation. DMF was not clastogenic in the in vivo micronucleus assay in the rat.

Impairment of Fertility

In male rats, oral administration of DMF (75, 250, and 375 mg/kg/day) prior to and throughout the mating period had no effect on fertility; however, increases in non-motile sperm were observed at the mid and high doses. The no-effect dose for adverse effects on sperm is similar to the recommended human dose (RHD) of 480 mg/day on a body surface area (mg/m2) basis.

In female rats, oral administration of DMF (20, 100, and 250 mg/kg/day) prior to and during mating and continuing to gestation day 7 caused disruption of the estrous cycle and increases in embryolethality at the highest dose tested. The highest dose not associated with adverse effects (100 mg/kg/day) is twice the RHD on a mg/m2 basis.

Testicular toxicity (germinal epithelial degeneration, atrophy, hypospermia, and/or hyperplasia) was observed at clinically relevant doses in mice, rats, and dogs in subchronic and chronic oral toxicity studies of DMF, and in a chronic oral toxicity study evaluating a combination of four fumaric acid esters (including DMF) in rats.

Animal Toxicology and/or Pharmacology

Kidney toxicity was observed after repeated oral administration of dimethyl fumarate (DMF) in mice, rats, dogs, and monkeys. Renal tubule epithelia regeneration, suggestive of tubule epithelial injury, was observed in all species. Renal tubular hyperplasia was observed in rats with dosing for up to two years. Cortical atrophy and interstitial fibrosis were observed in dogs and monkeys at doses above 5 mg/kg/day. In monkeys, the highest dose tested (75 mg/kg/day) was associated with single cell necrosis and multifocal and diffuse interstitial fibrosis, indicating irreversible loss of renal tissue and function. In dogs and monkeys, the 5 mg/kg/day dose was associated with plasma MMF exposures less than or similar to that in humans at the recommended human dose (RHD).

A dose-related increase in incidence and severity of retinal degeneration was observed in mice following oral administration of DMF for up to two years at doses above 75 mg/kg/day, a dose associated with plasma MMF exposure (AUC) similar to that in humans at the RHD.

Clinical Studies

The efficacy and safety of Tecfidera were demonstrated in two studies (Studies 1 and 2) that evaluated Tecfidera taken either twice or three times a day in patients with relapsing-remitting multiple sclerosis (RRMS). The starting dose for Tecfidera was 120 mg twice or three times a day for the first 7 days, followed by an increase to 240 mg twice or three times a day. Both studies included patients who had experienced at least 1 relapse over the year preceding the trial or had a brain Magnetic Resonance Imaging (MRI) scan demonstrating at least one gadolinium-enhancing (Gd+) lesion within 6 weeks of randomization. The Expanded Disability Status Scale (EDSS) was also assessed and patients could have scores ranging from 0 to 5. Neurological evaluations were performed at baseline, every 3 months, and at the time of suspected relapse. MRI evaluations were performed at baseline, month 6, and year 1 and 2 in a subset of patients (44% in Study 1 and 48% in Study 2).

Study 1: Placebo-Controlled Trial in RRMS

Study 1 was a 2-year randomized, double-blind, placebo-controlled study in 1234 patients with RRMS. The primary endpoint was the proportion of patients relapsed at 2 years. Additional endpoints at 2 years included the number of new or newly enlarging T2 hyperintense lesions, number of new T1 hypointense lesions, number of Gd+ lesions, annualized relapse rate (ARR), and time to confirmed disability progression. Confirmed disability progression was defined as at least a 1 point increase from baseline EDSS (1.5 point increase for patients with baseline EDSS of 0) sustained for 12 weeks.

Patients were randomized to receive Tecfidera 240 mg twice a day (n=410), Tecfidera 240 mg three times a day (n=416), or placebo (n=408) for up to 2 years. The median age was 39 years, median time since diagnosis was 4 years, and median EDSS score at baseline was 2. The median time on study drug for all treatment arms was 96 weeks. The percentages of patients who completed 96 weeks on study drug per treatment group were 69% for patients assigned to Tecfidera 240 mg twice a day, 69% for patients assigned to Tecfidera 240 mg three times a day and 65% for patients assigned to placebo groups.

Tecfidera had a statistically significant effect on all of the endpoints described above and the 240 mg three times daily dose showed no additional benefit over the Tecfidera 240 mg twice daily dose. The results for this study (240 mg twice a day vs. placebo) are shown in Table 2 and Figure 1.

Study 2: Placebo-Controlled Trial in RRMS

Study 2 was a 2-year multicenter, randomized, double-blind, placebo-controlled study that also included an open-label comparator arm in patients with RRMS. The primary endpoint was the annualized relapse rate at 2 years. Additional endpoints at 2 years included the number of new or newly enlarging T2 hyperintense lesions, number of T1 hypointense lesions, number of Gd+ lesions, proportion of patients relapsed, and time to confirmed disability progression as defined in Study 1.

Patients were randomized to receive Tecfidera 240 mg twice a day (n=359), Tecfidera 240 mg three times a day (n=345), an open-label comparator (n=350), or placebo (n=363) for up to 2 years. The median age was 37 years, median time since diagnosis was 3 years, and median EDSS score at baseline was 2.5. The median time on study drug for all treatment arms was 96 weeks. The percentages of patients who completed 96 weeks on study drug per treatment group were 70% for patients assigned to Tecfidera 240 mg twice a day, 72% for patients assigned to Tecfidera 240 mg three times a day and 64% for patients assigned to placebo groups.

Tecfidera had a statistically significant effect on the relapse and MRI endpoints described above. There was no statistically significant effect on disability progression. The Tecfidera 240 mg three times daily dose resulted in no additional benefit over the Tecfidera 240 mg twice daily dose. The results for this study (240 mg twice a day vs. placebo) are shown in Table 3.

Advise patients to discontinue Tecfidera and seek medical care if they develop signs and symptoms of anaphylaxis or angioedema [see Warnings and Precautions (5.1)].

Progressive Multifocal Leukoencephalopathy

Inform patients that progressive multifocal leukoencephalopathy (PML) has occurred in patients who received Tecfidera. Inform the patient that PML is characterized by a progression of deficits and usually leads to death or severe disability over weeks or months. Instruct the patient of the importance of contacting their doctor if they develop any symptoms suggestive of PML. Inform the patient that typical symptoms associated with PML are diverse, progress over days to weeks, and include progressive weakness on one side of the body or clumsiness of limbs, disturbance of vision, and changes in thinking, memory, and orientation leading to confusion and personality changes [see Warnings and Precautions (5.2)].

Lymphocyte Counts

Inform patients that Tecfidera may decrease lymphocyte counts. A blood test should be obtained before they start therapy. Blood tests are also recommended after 6 months of treatment, every 6 to 12 months thereafter, and as clinically indicated [see Warnings and Precautions (5.3), Adverse Reactions (6.1)].

Liver Injury

Inform patients that Tecfidera may cause liver injury. Instruct patients treated with Tecfidera to report promptly any symptoms that may indicate liver injury, including fatigue, anorexia, right upper abdominal discomfort, dark urine, or jaundice. A blood test should be obtained before patients start therapy and during treatment, as clinically indicated [see Warnings and Precautions (5.4)].

Flushing and Gastrointestinal (GI) Reactions

Flushing and GI reactions (abdominal pain, diarrhea, and nausea) are the most common reactions, especially at the initiation of therapy, and may decrease over time. Advise patients to contact their healthcare provider if they experience persistent and/or severe flushing or GI reactions. Advise patients experiencing flushing that taking Tecfidera with food or taking a non-enteric coated aspirin prior to taking Tecfidera may help [see Adverse Reactions (6.1)].

Pregnancy and Pregnancy Registry

Instruct patients that if they are pregnant or plan to become pregnant while taking Tecfidera they should inform their physician.
