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。
妊娠注册
有一个妊娠注册监视在妊娠期间暴露于TECFIDERA妇女妊娠结果。鼓励患者报名参加通过电话1-800-456-2255。
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。

1 ANNEX I SUMMARY OF PRODUCT CHARACTERISTICS 2 1. NAME OF THE MEDICINAL PRODUCT Skilarence 30 mg gastro-resistant tablets Skilarence 120 mg gastro-resistant tablets 2. QUALITATIVE AND QUANTITATIVE COMPOSITION Skilarence 30 mg Each gastro-resistant tablet contains 30 mg dimethyl fumarate. Skilarence 120 mg Each gastro-resistant tablet contains 120 mg dimethyl fumarate. Excipient with known effect Skilarence 30 mg Each gastro-resistant tablet contains 34.2 mg lactose (as monohydrate). Skilarence 120 mg Each gastro-resistant tablet contains 136.8 mg lactose (as monohydrate). For the full list of excipients, see section 6.1. 3. PHARMACEUTICAL FORM Gastro-resistant tablet. Skilarence 30 mg White, film-coated, round, biconvex tablet with a diameter of approximately 6.8 mm. Skilarence 120 mg Blue, film-coated, round, biconvex tablet with a diameter of approximately 11.6 mm. 4. CLINICAL PARTICULARS 4.1 Therapeutic indications Skilarence is indicated for the treatment of moderate to severe plaque psoriasis in adults in need of systemic medicinal therapy. 4.2 Posology and method of administration Skilarence is intended for use under the guidance and supervision of a physician experienced in the diagnosis and treatment of psoriasis. Posology To improve tolerability, it is recommended to begin treatment with a low initial dose with subsequent gradual increases. In the first week, Skilarence 30 mg is taken once daily (1 tablet in the evening). In the second week, Skilarence 30 mg is taken twice daily (1 tablet in the morning and 1 in the evening). In the third week, Skilarence 30 mg is taken three times daily (1 tablet in the morning, 1 at midday, and 1 in the evening). From the fourth week, treatment is switched to only 1 tablet of Skilarence 120 mg in the evening. This dose is then increased by 1 Skilarence 120 mg tablet per week at different times of day for the subsequent 5 weeks, as shown in the table below. The maximum daily dose allowed is 720 mg (3 x 2 tablets of Skilarence 120 mg). 3 Week Number of tablets Total daily dose (mg) Morning Midday Evening of dimethyl fumarate Skilarence 30 mg 1 0 0 1 30 2 1 0 1 60 3 1 1 1 90 Skilarence 120 mg 4 0 0 1 120 5 1 0 1 240 6 1 1 1 360 7 1 1 2 480 8 2 1 2 600 9+ 2 2 2 720 If a particular dose increase is not tolerated, it may be temporarily reduced to the last tolerated dose. If treatment success is observed before the maximum dose is reached, no further increase of dose is necessary. After clinically relevant improvement of the skin lesions has been achieved, consideration should be given to gradual reduction of the daily dose of Skilarence to the maintenance dose required by the individual. Dosage modifications may also be necessary if abnormalities in laboratory parameters are observed (see section 4.4). Elderly patients Clinical studies of Skilarence did not include sufficient numbers of patients aged 65 years and above to determine whether they respond differently compared to patients under 65 years (see section 5.2). Based on the pharmacology of dimethyl fumarate, a need for dose adjustment in the elderly is not expected. Renal impairment No dose adjustment is needed in patients with mild to moderate renal impairment (see section 5.2). Skilarence has not been studied in patients with severe renal impairment, and use of Skilarence is contraindicated in these patients (see section 4.3). Hepatic impairment No dose adjustment is needed in patients with mild to moderate hepatic impairment (see section 5.2). Skilarence has not been studied in patients with severe hepatic impairment, and use of Skilarence is contraindicated in these patients (see section 4.3). Paediatric population The safety and efficacy of Skilarence in paediatric patients below the age of 18 years have not been established. There are no data available with Skilarence in paediatric patients. Method of administration Skilarence is for oral use. Skilarence tablets must be swallowed whole with fluid during or immediately after a meal. The coating of the gastro-resistant tablets is designed to prevent gastric irritation. Therefore, the tablets should not be crushed, divided, dissolved or chewed. 4 4.3 Contraindications ‒ Hypersensitivity to the active substance or to any of the excipients listed in section 6.1. ‒ Severe gastrointestinal disorders. ‒ Severe hepatic or renal impairment. ‒ Pregnancy and breast-feeding. 4.4 Special warnings and precautions for use Haematology Skilarence may decrease leukocyte and lymphocyte counts (see section 4.8). It has not been studied in patients with pre-existing low leukocyte or lymphocyte counts. Before treatment Prior to initiating treatment with Skilarence, a current complete blood count (including differential blood count and platelet count) should be available. Treatment should not be initiated if leukopenia below 3.0x109 /L, lymphopenia below 1.0x109 /L or other pathological results are identified. During treatment During treatment a complete blood count with differential should be performed every 3 months. Action is needed in the following circumstances: Leukopenia: If a marked decrease in the total number of white blood cells is found, the situation should be monitored carefully and treatment with Skilarence should be discontinued at levels below 3.0x109 /L. Lymphopenia: If the lymphocyte count falls below 1.0x109 /L but is ≥0.7 x109 /L, blood monitoring should be performed monthly until levels return to 1.0x109 /L or higher for two consecutive blood tests at which point monitoring can again be performed every 3 months. If the lymphocyte count falls below 0.7x109 /L, the blood test must be repeated and if the levels are confirmed to be below 0.7x109 /L, then treatment must be stopped immediately. Patients developing lymphopenia should be monitored after stopping treatment until their lymphocyte count has returned to the normal range (see section 4.8). Other haematological disorders Therapy should be discontinued and caution is advised if other pathological results occur. In any case blood counts should be monitored until values have returned to the normal range. Infections Skilarence is an immunomodulator and may affect the way the immune system responds to infection. For patients with pre-existing infections of clinical relevance, the physician should decide if treatment with Skilarence should only be initiated once the infection has resolved. If a patient develops an infection during treatment with Skilarence, suspension of treatment should be considered and the benefits and risks should be reassessed prior to re-initiation of therapy. Patients receiving Skilarence should be instructed to report symptoms of infection to a physician. Opportunistic infections/progressive multifocal leukoencephalopathy (PML) Cases of opportunistic infections, particularly of progressive multifocal leukoencephalopathy (PML) have been reported with other dimethyl fumarate-containing products (see section 4.8). PML is an opportunistic infection caused by the John-Cunningham virus (JCV) that can be fatal or cause severe disabilities. PML is probably caused by a combination of factors. A previous infection with JCV is considered a prerequisite for the development of PML. Risk factors can include previous immunosuppressive treatment and the existence of certain concomitant disorders (such as some autoimmune disorders or malignant haematological conditions). A modified or weakened immune system as well as genetic or environmental factors can also constitute risk factors. 5 Persistent moderate or severe lymphopenia during treatment with dimethyl fumarate is also considered a risk factor for PML. Patients who develop lymphopenia should be monitored for signs and symptoms of opportunistic infections, particularly for symptoms indicative of PML. Typical symptoms associated with PML are diverse, become worse 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. If PML is suspected, treatment with Skilarence should be stopped immediately and further appropriate neurological and radiological examinations performed. Prior and concomitant treatment with immunosuppressive or immunomodulating therapies Limited data are available on the efficacy and safety of Skilarence in patients who have been previously treated with other immunosuppressive or immunomodulating therapies. When switching patients from such therapies to Skilarence, the half-life and mode of action of the other therapy should be considered in order to avoid additive effects on the immune system. No data are available on the efficacy and safety of Skilarence when taken concomitantly with other immunosuppressive or immunomodulating therapies (see section 4.5). Pre-existing gastrointestinal disease Skilarence has not been studied in patients with pre-existing gastrointestinal disease. Skilarence is contraindicated in patients with severe gastrointestinal disease (see sections 4.3). Gastrointestinal tolerability can be improved by following the dose titration schedule on initiating Skilarence treatment and by taking Skilarence with food (see sections 4.2 and 4.8). Renal function Since renal elimination plays a minor role in the clearance of Skilarence from plasma, it is unlikely that renal impairment would affect the pharmacokinetic characteristics, and so a need for dose adjustment in patients with mild to moderate renal impairment is not expected (see sections 4.2 and 5.2). During the Phase III placebo-controlled clinical trial, renal function was not seen to deteriorate during therapy across treatment groups. However, Skilarence has not been studied in patients with severe renal impairment, and some cases of renal toxicity have been reported during post-marketing surveillance with fumaric acid esters. Hence, Skilarence is contraindicated in patients with severe renal impairment (see section 4.3). Renal function (e.g. creatinine, blood urea nitrogen and urinalysis) should be checked prior to initiation of treatment and every 3 months thereafter. In the event of a clinically relevant change in renal function, particularly in the absence of alternative explanations, consideration should be given to dosage reduction or treatment discontinuation. Fanconi syndrome Early diagnosis of Fanconi syndrome and discontinuation of Skilarence treatment are important to prevent the onset of renal impairment and osteomalacia, as the syndrome is usually reversible. The most important signs are: proteinuria, glucosuria (with normal blood sugar levels), hyperaminoaciduria and phosphaturia (possibly concurrent with hypophosphatemia). Progression might involve symptoms such as polyuria, polydipsia and proximal muscle weakness. In rare cases hypophosphataemic osteomalacia with non-localised bone pain, elevated alkaline phosphatase in serum and stress fractures may occur. Importantly, Fanconi syndrome can occur without elevated creatinine levels or low glomerular filtration rate. In case of unclear symptoms Fanconi syndrome should be considered and appropriate examinations should be performed. Hepatic function Skilarence has not been studied in patients with severe hepatic impairment and is contraindicated in these patients (see section 4.3). It is recommended to monitor hepatic function (SGOT, SGPT, gamma-GT, AP) prior to initiation of 6 treatment and every 3 months thereafter, since elevation of hepatic enzymes has been observed in some patients in the Phase III study. In the event of a clinically relevant change in hepatic parameters, particularly in the absence of alternative explanations, consideration should be given to dose reduction or treatment discontinuation. Flushing Patients should be made aware that they are likely to experience flushing in the first few weeks of taking Skilarence (see section 4.8). Lactose Skilarence contains lactose. Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicinal product. 4.5 Interaction with other medicinal products and other forms of interaction No interaction studies have been performed. Skilarence should be used cautiously in combination with other systemic antipsoriatic therapy (e.g. methotrexate, retinoids, psoralens, ciclosporin, immunosuppressants or cytostatics) (see section 4.4). During treatment with Skilarence, simultaneous use of other fumaric acid derivatives (topical or systemic) should be avoided. Concurrent therapy with nephrotoxic substances (e.g. methotrexate, ciclosporin, aminoglycosides, diuretics, NSAIDs or lithium) may increase the potential for renal adverse reactions (e.g. proteinuria) in patients taking Skilarence. In cases of severe or prolonged diarrhoea during treatment with Skilarence, absorption of other medicinal products may be affected. Caution should be exercised when prescribing medicinal products with a narrow therapeutic index that require absorption in the intestinal tract. The efficacy of oral contraceptives may be reduced and the use of an alternative barrier contraceptive method is recommended to prevent possible failure of contraception (see the prescribing information of the oral contraceptive). Consumption of large quantities of strong alcoholic drinks (more than 30% alcohol by volume) should be avoided because it may lead to increased dissolution rates of Skilarence and, therefore, may increase the frequency of gastrointestinal adverse reactions. Vaccination during treatment with Skilarence has not been studied. Immunosuppression is a risk factor for the use of live vaccines. The risk of vaccination should be weighed against the benefit. There is no evidence for Skilarence interaction with cytochrome P450 and the most common efflux and uptake transporters, thus no interactions are expected with medicinal products metabolised or transported by these systems (see section 5.2). 4.6 Fertility, pregnancy and lactation Women of child-bearing potential Skilarence is not recommended in women of child-bearing potential not using appropriate contraception. In patients experiencing diarrhoea during Skilarence treatment, the effect of oral contraceptives may be reduced and additional barrier methods of contraception may be necessary (see section 4.5). Pregnancy There are limited data from the use of dimethyl fumarate in pregnant women. Animal studies have shown reproductive toxicity (see section 5.3). Skilarence is contraindicated during pregnancy (see section 4.3). 7 Breast-feeding It is unknown whether dimethyl fumarate or its metabolites are excreted in human milk. A risk to newborns or infants cannot be excluded. Therefore, Skilarence is contraindicated during breastfeeding (see section 4.3). Fertility There are no human or animal data on the effects of Skilarence on fertility. 4.7 Effects on ability to drive and use machines No studies on the ability to drive and use machines have been conducted. Skilarence may have a minor influence on the ability to drive and use machines. Dizziness and fatigue may occur following administration of Skilarence (see section 4.8). 4.8 Undesirable effects Summary of the safety profile The most common adverse reactions observed with Skilarence in the Phase III clinical study (1102) in psoriasis patients were gastrointestinal events (62.7%), flushing (20.8%) and lymphopenia (10.0%). Most adverse reactions were considered mild and did not lead to discontinuation of study treatment. The only adverse reactions that led to discontinuation of treatment in >5% of patients were gastrointestinal reactions. For monitoring recommendations and clinical management of adverse reactions, see section 4.4. Tabulated list of adverse reactions The following is a list of adverse reactions experienced by patients treated with Skilarence during the clinical study and with Fumaderm, a related medicinal product containing dimethyl fumarate along with other fumaric acid esters. The frequency of adverse reactions is defined using the following convention: very common (≥1/10); common (≥1/100 to <1/10); uncommon (≥1/1,000 to <1/100); rare (≥1/10,000 to <1/1,000); very rare (<1/10,000); and not known (cannot be estimated from available data).

Description of selected adverse reactions Gastrointestinal disturbances Data from the Phase III clinical study as well as from the literature show that gastrointestinal disorders with dimethyl fumarate-containing products are most likely to occur during the first 2 to 3 months after starting treatment. No apparent dose relationship and no risk factors for the occurrence of these adverse reactions could be identified. Diarrhoea was a common adverse reaction (36.9%) among patients taking Skilarence, leading to medicinal product withdrawal in about 10% of patients. More than 90% of these diarrhoea events were of mild to moderate severity (see section 4.4). Flushing Based on observations in the Phase III clinical study as well as on literature data, flushing is most likely to occur during the early weeks of treatment and tends to lessen with time. In the clinical study a total of 20.8% of patients receiving Skilarence experienced flushing, which was mild in the majority of cases (see section 4.4). Published clinical experience with dimethyl fumarate-containing products shows that individual episodes of flushing usually begin shortly after taking the tablets and resolve within a few hours. Haematological changes Data from the Phase III clinical study as well as from the literature show that changes in haematological parameters are most likely to occur during the first 3 months after starting treatment with dimethyl fumarate. In particular, in the clinical study there was a slight decrease in mean lymphocyte counts starting between weeks 3 and 5 and reaching a maximum in week 12 where approximately one third of patients had lymphocyte values below 1.0x109 /L. The mean and median values of lymphocytes remained within the normal range during the clinical study. At week 16 (end of treatment), there was no further decline in lymphocyte counts. At week 16 of treatment, 13/175 (7.4%) of patients were noted to have lymphocyte levels <0.7x 109 /L. Blood sampling for safety clinical laboratory tests at follow-up visits was only performed in case of abnormalities at the preceeding visit. During the treatment free follow up, lymphocyte levels of <0.7x 109 /L were observed in 1/29 (3.5%) patient at 6 months and 0/28 (0%) at 12 months after stopping treatment. At 12 months after stopping treatment 3/28 (10.7%) of patients had lymphocyte values below 1.0x109 /L, which would represent 3/279 (1.1%) of the patients started on Skilarence. For the total leukocyte count, a decline became apparent at week 12 of treatment; it slowly increased again at week 16 (end of treatment); and 12 months after stopping treatment all patients had values above 3.0x109 /L. A transient increase in mean values of eosinophils was noted as early as week 3, reached a maximum at week 5 and 8, and had returned to baseline values at week 16. 9 For monitoring recommendations and clinical management of haematological adverse reactions, see section 4.4. Reporting of suspected adverse reactions Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the national reporting system listed in Appendix V. 4.9 Overdose Symptomatic treatment is indicated in the case of an overdose. No specific antidote is known. 5. PHARMACOLOGICAL PROPERTIES 5.1 Pharmacodynamic properties Pharmacotherapeutic group: ATC code: not yet assigned Mechanism of action The anti-inflammatory and immunomodulating effects of dimethyl fumarate and its metabolite monomethyl fumarate are not fully elucidated but are thought to be mainly due to the interaction with the intracellular reduced glutathione of cells directly involved in the pathogenesis of psoriasis. This interaction with glutathione leads to the inhibition of translocation into the nucleus and the transcriptional activity of the nuclear factor kappa-light-chain-enhancer of activated B-cells (NF-κB). The main activity of dimethyl fumarate and monomethyl fumarate is considered to be immunomodulatory, resulting in a shift in T helper cells (Th) from the Th1 and Th17 profile to a Th2 phenotype. The inflammatory cytokine production is reduced with induction of proapoptotic events, inhibition of keratinocyte proliferation, reduced expression of adhesion molecules, and diminished inflammatory infiltrate within psoriatic plaques. Clinical efficacy and safety The safety and efficacy of Skilarence was assessed in one double-blind, 3-arm, placebo- and active comparator-controlled Phase III study (1102) in patients with moderate to severe plaque psoriasis (Study 1102). 704 patients were randomised to receive Skilarence, an active comparator (Fumaderm, a combination product with the same content of dimethyl fumarate plus 3 monoethyl fumarate salts) and placebo in a ratio of 2:2:1. Patients began treatment with tablets containing 30 mg/day dimethyl fumarate or placebo, titrating up to a maximum of 720 mg/day in both active treatment arms as described in section 4.2. If treatment success was observed before the maximum dose of 720 mg/day of dimethyl fumarate was reached, no further increase of dosage was necessary and the dosage was to be steadily reduced to an individual maintenance dose. In case of individual intolerability of the increased dosage during weeks 4 to 16, the patient was to return to the last tolerated dose taken since the start of week 4, which was to be maintained until end of the treatment period (week 16). Patients received treatment for up to 16 weeks and follow-up visits were planned for up to 12 months after treatment was stopped. The demographic and baseline characteristics were well balanced between the treatment groups. Of the 699 patients, most were Caucasian (99%) and male (65%), and the mean age was 44 years. Most patients (91%) were <65 years of age. Most patients had moderate psoriasis based on Psoriasis Area and Severity Index (PASI) and Physician’s Global Assessment (PGA) scores at baseline: the mean PASI score at baseline was 16.35 and 60% of patients scored as moderate on the PGA. The majority of patients reported a “very large” or “extremely large” effect of psoriasis on their life based on the Dermatology Life Quality Index (DLQI), with a mean DLQI score of 11.5. After 16 weeks of treatment, Skilarence was found to be superior to placebo (p<0.0001) based on 10 PASI 75 and PGA score clear or almost clear and non-inferior (using a non-inferiority margin of -15%) to the active comparator (p<0.0003) based on PASI 75.

There was a trend in the efficacy endpoint PASI score mean % change from baseline, indicating the onset of a clinical response to Skilarence as early as week 3 (-11.8%) which became statistically significant compared to placebo by week 8 (-30.9%). Further improvement was seen by week 16 (-50.8%). The benefits of treatment with Skilarence were also supported by patient self-perceived improvements in their quality of life. At week 16, patients treated with Skilarence had a lower mean DLQI compared to placebo (5.4 vs 8.8). Rebound (defined as worsening of ≥125% of baseline PASI value) was assessed after 2 months off treatment and was shown not to be a clinical concern with fumaric acid esters, as it was documented in very few patients (Skilarence 1.1% and active comparator 2.2%, compared to 9.3% in the placebo group). Long-term efficacy data are currently not available for Skilarence, however, in the pharmacokinetic and clinical studies the systemic exposure, efficacy and safety of Skilarence were shown to be comparable to the active comparator containing dimethyl fumarate. Hence it is reasonable to expect the long-term efficacy of Skilarence to also be comparable to dimethyl fumarate-containing products. Maintenance of long term efficacy has been well described for other dimethyl fumarate-containing products, and therefore the treatment benefits seen with Skilarence at 16 weeks can be expected to be maintained in patients treated over the long term for at least 24 months. 11 Paediatric population The European Medicines Agency has waived the obligation to submit the results of studies with Skilarence in all subsets of the paediatric population in this indication (see section 4.2 for information on paediatric use). 5.2 Pharmacokinetic properties Absorption After oral administration, dimethyl fumarate is not detected in plasma because it is rapidly hydrolysed by esterases to its active metabolite monomethyl fumarate. After oral administration of a single Skilarence 120 mg tablet in healthy subjects, monomethyl fumarate reached plasma peak concentrations of around 1325 ng/mL and 1311 ng/mL under fasted or fed conditions, respectively. Taking Skilarence with food delayed the tmax of monomethyl fumarate from 3.5 to 9.0 hours. Distribution The plasma protein binding of monomethyl fumarate is around 50%. Dimethyl fumarate does not show any binding affinity to serum proteins which may further contribute to its rapid elimination from the circulation. Biotransformation The biotransformation of dimethyl fumarate does not involve cytochrome P450 isoenzymes. In vitro studies have shown that monomethyl fumarate at the therapeutic dose does not inhibit or induce any of the cytochrome P450 enzymes, it is not a substrate or inhibitor of P-glycoprotein and is not an inhibitor of the most common efflux and uptake transporters. In vitro studies have shown that hydrolysis of dimethyl fumarate to monomethyl fumarate occurs rapidly at pH 8 (pH in the small intestine), but not at pH 1 (pH in the stomach). A part of the total dimethyl fumarate is hydrolysed by esterases and the alkaline milieu of the small intestine, while the remainder enters the portal vein blood. Further studies have shown that dimethyl fumarate (and to a lesser extent monomethyl fumarate) reacts partially with reduced glutathione forming a glutathioneadduct. These adducts were detected in animal studies in the intestinal mucosa of rats and to a smaller extent in portal vein blood. Unconjugated dimethyl fumarate, however, cannot be detected in the plasma of animals or psoriatic patients following oral administration. By contrast, unconjugated monomethyl fumarate is detectable in plasma. Further metabolism occurs through oxidation via the tricarboxylic acid cycle forming carbon dioxide and water. Elimination Exhalation of CO2 resulting from the metabolism of monomethyl fumarate is the primary route of elimination; only small amounts of intact monomethyl fumarate are excreted through urine or faeces. The portion of dimethyl fumarate that reacts with glutathione, forming a glutathione-adduct, is metabolised further to its mercapturic acid, which is excreted in the urine. The apparent terminal elimination half-life of monomethyl fumarate is about 2 hours. Linearity/non-linearity Despite the high inter-subject variability, the exposure measured as AUC and Cmax was generally dose-proportional after single dose administration of 4 x 30 mg dimethyl fumarate tablets (total dose of 120 mg) and 2 x 120 mg dimethyl fumarate tablets (total dose of 240 mg). Renal impairment No specific studies have been performed in patients with renal impairment. However, because renal elimination plays a minor role in the total clearance from plasma, it is unlikely that renal impairment may affect the pharmacokinetic characteristics of Skilarence (see section 4.2). Hepatic impairment No specific studies have been performed in patients with hepatic impairment. However, as dimethyl fumarate is metabolised by esterases and the alkaline milieu of the small intestine without the 12 involvement of cytochrome P450, hepatic impairment is not expected to influence exposure (see section 4.2). 5.3 Preclinical safety data Non-clinical safety pharmacology and genotoxicity data reveal no special hazard for humans. Toxicology The kidney was identified as a major target organ of toxicity in non-clinical studies. Renal findings in dogs included minimal to moderate tubular hypertrophy, increased incidence and severity of tubular vacuolation and minimal to slight tubular degeneration, which were considered toxicologically relevant. The no-observed adverse-effect-level (NOAEL) after 3 months of treatment was 30 mg/kg/day, which corresponds to 2.9-fold and 9.5-fold the human systemic exposure at the highest recommended dose (720 mg/day), as AUC and Cmax values, respectively. Reproduction toxicity No fertility or pre- and post-natal development studies have been conducted with Skilarence. There were no effects on foetal body weights or malformations attributed to maternal administration of dimethyl fumarate during the embryo-foetal development study in rats. However, there was an increased number of foetuses with the variations “supernumerary liver lobe” and “abnormal iliac alignment” at maternally toxic doses. The NOAEL for maternal and embryo-foetal toxicity was 40 mg/kg/day, corresponding to 0.2-fold and 2.0-fold the human systemic exposure at the highest recommended dose (720 mg/day), as AUC and Cmax values, respectively. Dimethyl fumarate has been shown to cross the placental membrane into foetal blood in rats. Carcinogenicity No carcinogenicity studies have been performed for Skilarence. Based on available data suggesting that fumaric acid esters may activate cellular pathways related to the development of renal tumours, a potential tumorigenic activity of exogenously administered dimethyl fumarate on the kidneys cannot be excluded. 6.

PACKAGE LEAFLET 28 Package leaflet: Information for the patient Skilarence 30 mg gastro-resistant tablets dimethyl fumarate Read all of this leaflet carefully before you start taking this medicine because it contains important information for you. - Keep this leaflet. You may need to read it again. - If you have any further questions, ask your doctor or pharmacist. - This medicine has been prescribed for you only. Do not pass it on to others. It may harm them, even if their signs of illness are the same as yours. - If you get any side effects, talk to your doctor or pharmacist. This includes any possible side effects not listed in this leaflet. See section 4. What is in this leaflet 1. What Skilarence is and what it is used for 2. What you need to know before you take Skilarence 3. How to take Skilarence 4. Possible side effects 5. How to store Skilarence 6. Contents of the pack and other information 1. What Skilarence is and what it is used for What Skilarence is Skilarence is a medicine that contains the active substance dimethyl fumarate. Dimethyl fumarate works on cells of the immune system (the body's natural defences). It changes the activity of the immune system and reduces the production of substances involved in causing psoriasis. What Skilarence is used for Skilarence tablets are used to treat moderate to severe plaque psoriasis in adults. Psoriasis is a disease causing thickened, inflamed, red areas on the skin, often covered by silvery scales. Response to Skilarence can be generally seen as early as week 3 and improves over time. Experience with related products containing dimethyl fumarate shows treatment benefit for at least up to 24 months. 2. What you need to know before you take Skilarence Do not take Skilarence - if you are allergic to dimethyl fumarate or any of the other ingredients of this medicine (listed in section 6) - if you have severe problems with your stomach or intestines - if you have severe liver or kidney problems - if you are pregnant or breast-feeding Warnings and precautions Talk to your doctor or pharmacist before taking Skilarence. Monitoring Skilarence may cause problems with your blood, liver or kidneys. You will have blood and urine tests before treatment and then regularly during your treatment to make sure that you are not getting these 29 complications and can continue to take this medicine. Depending on the results of these blood and urine tests, your doctor may reduce your dose of Skilarence or stop treatment. Infections White blood cells help your body to fight infections. Skilarence may reduce the number of your white blood cells. Talk to your doctor if you think you may have an infection. Symptoms include fever, pain, aching muscles, headache, loss of appetite and a general feeling of weakness. If you have a serious infection, either before starting treatment with Skilarence or during treatment, your doctor may advise you not to take Skilarence until the infection has resolved. Gastrointestinal disorders Tell your doctor if you have or have had problems with your stomach or intestines. Your doctor will advise you on what care you need to take during Skilarence treatment. Children and adolescents Children and adolescents below the age of 18 years should not take this medicine because it has not been studied in this age group. Other medicines and Skilarence Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. In particular, tell your doctor if you are taking the following: - Dimethyl fumarate or other fumarates. The active ingredient in Skilarence, dimethyl fumarate, is also used in other medicines such as tablets, ointments and baths. You must avoid using other products that contain fumarates to prevent taking too much. - Other medicines used to treat psoriasis, such as methotrexate, retinoids, psoralens, ciclosporin, or other immunosuppressants or cytostatics (medicines that affect the immune system). Taking these medicines with Skilarence could increase the risk of side effects on your immune system. - Other medicines that can affect your kidney function, such as methotrexate or ciclosporin (used to treat psoriasis), aminoglycosides (used to treat infections), diuretics (which increase urine), nonsteroidal anti-inflammatory drugs (used to treat pain) or lithium (used for bipolar disease and depression). These medicines taken together with Skilarence could increase the risk of side effects on your kidneys. If you get severe or prolonged diarrhoea with Skilarence, other medicines may not work as well as they should. Talk to your doctor if you have bad diarrhoea and are concerned that other medicines you are taking might not work. In particular, if you are taking a contraceptive medicine (the pill), the effect may be reduced and you may need to use other barrier methods to prevent pregnancy. See the instructions in the patient leaflet of the contraceptive you are taking. If you need a vaccination, talk to your doctor. Certain types of vaccines (live vaccines) may cause infection if used during treatment with Skilarence. Your doctor can advise you what would be best. Skilarence with alcohol Avoid strong alcoholic drinks (more than 50 ml of spirits containing more than 30% alcohol by volume) during treatment with Skilarence, as alcohol can interact with this medicine. This could cause stomach and intestinal problems. Pregnancy and breast-feeding Do not take Skilarence if you are pregnant or trying to become pregnant, as Skilarence may harm your baby. Use effective methods of contraception to avoid becoming pregnant during treatment with Skilarence (see also “Other medicines and Skilarence” above). Do not breast-feed during treatment with Skilarence. 30 Driving and using machines Skilarence may have a minor influence on the ability to drive and use machines. You may feel dizzy or tired after taking Skilarence. If you are affected, be careful when driving or using machines. Skilarence contains lactose If you have been told by your doctor that you have an intolerance to some sugars, speak with your doctor before taking this medicine. 3. How to take Skilarence Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure. Dose Your doctor will start your treatment with a low dose (using 30 mg Skilarence tablets). This helps to reduce stomach problems and other side effects. Your dose will be increased every week as shown in the table below (switching to 120 mg Skilarence tablets from week 4 onwards). Treatment week Tablet strength How many tablets to take during the day Number of tablets per day Total daily dose Breakfast Lunch Evening meal 1 30 mg ‒ ‒ 1 1 30 mg 2 30 mg 1 ‒ 1 2 60 mg 3 30 mg 1 1 1 3 90 mg 4 120 mg ‒ ‒ 1 1 120 mg 5 120 mg 1 ‒ 1 2 240 mg 6 120 mg 1 1 1 3 360 mg 7 120 mg 1 1 2 4 480 mg 8 120 mg 2 1 2 5 600 mg 9+ 120 mg 2 2 2 6 720 mg Your doctor will check how well your condition is improving after you start taking Skilarence and will check for side effects. If you have severe side effects after an increase in dose, your doctor may recommend that you temporarily go back to the last dose. If the side effects are not troublesome, your dose will be increased until your condition is well controlled. You may not need the maximum dose of 720 mg per day. After your condition has improved sufficiently, your doctor will consider how to gradually reduce the daily dose of Skilarence to what you need to maintain your improvement. Method of administration Swallow Skilarence tablets whole with liquid. Take your tablets during or immediately after a meal. Do not crush, break, dissolve or chew your tablets, as they have a special coating to help prevent irritation of your stomach. If you take more Skilarence than you should If you think you have taken too many Skilarence tablets, talk to your doctor or pharmacist. If you forget to take Skilarence Do not take a double dose to make up for a forgotten dose.
