近日,美国食品和药物管理局(FDA)批准Jivi(antihemophilic factor[recombinant],PEGylated-aucl)用于以前治疗过的成人和青少年血友病A的常规预防性治疗。TS 12岁或以上。JiVi最初推荐的预防方案是每周两次,每五天剂量一次,并根据出血事件进一步单独调整较少或更频繁的给药。 批准日期:2018年8月30日 公司:拜耳公司 JIVI(抗血友病因子[重组体],聚乙二醇化-AUCL[antihemophilic factor])冻干粉溶液,静脉注射用 首次美国批准:2018 作用机理 Jivi是一种位点特异性PEG化的重组抗血友病因子[见描述],暂时取代凝血因子VIII。A3结构域的位点特异性PEG化减少与生理因子VIII清除受体的结合,导致延长的半衰期和增加AUC[见临床药理学] 适应症及用法 Jivi,抗血友病因子(重组),PEGylated-aucl,是一种重组DNA衍生的第VIII因子浓缩物,用于先前治疗的成人和青少年(12岁及以上)血友病A(先天性第VIII因子缺乏): 对出血事件的按需治疗和控制出血的围手术期处理常规预防以减少出血次数。 使用限制 Jivi在12岁以下儿童不宜使用,因为过敏反应的风险更大。 Jivi未指示用于以前未治疗的患者(幼犬)。 Jivi未被用于治疗von Willebrand病。 剂量与给药 仅在重建后静脉使用。 出血事件的控制与围手术期处理 ●预期恢复:吉维每公斤体重1单位将使第八因子水平增加2国际单位每分升(IU/dL)。每一瓶JIVI含有标记的重组因子Ⅷ在IU中。 ·所需剂量(IU)=体重(kg)x期望因子VIII上升(正常或IU/dL百分比)x期望恢复(或观察恢复,如果有的话)的倒数。 ·因子Ⅷ(IU/DL或%的正常)的估计增量=[总剂量(IU)/体重(kg)] X2(IU/DL每IU/kg)。 常规预防 推荐的初始方案为30~40 IU/kg每周两次。 基于出血事件: 该方案可每5天调整45~60 IU/kg。 一种方案可进一步单独调整,以减少或更频繁地给药。 剂型和强度 JIVI可作为冻干粉在单用小瓶中含有500, 1000, 2000或3000 IU。 禁忌症 不要用于对活性物质、聚乙二醇(PEG)、小鼠或仓鼠蛋白、产品的口香糖成分有过敏反应史的患者。 警告和注意事项 发生过敏反应,包括严重的过敏反应。监测患者的过敏症状。发生过敏症状,用JIVI停止治疗,并给予相应的治疗。过敏反应也可能与抗聚乙二醇(PEG)抗体有关。 可产生因子Ⅷ中和抗体。如果未达到预期的血浆第VIII因子活性水平,或者给药剂量未能如预期控制出血,则进行测定第VIII因子抑制剂浓度的测定。 ·对PEG的免疫应答,表现为急性过敏和/或药物效应丧失的症状,主要在<6岁的受试者中观察到。评估在缺乏可检测因子VIII抑制剂的情况下出现过敏反应症状的患者,以防可能的出血或减少康复。 不良反应 在临床试验中报告最多的不良反应是头痛、咳嗽、恶心和发烧。 要报告可疑的不良反应,请联系拜耳AT1-88—842-937或FDA在1-800—FDA-1088或www. fd.gv/MeWAT。 在特定人群中的使用 儿科应用:Jivi不适用于12岁以下儿童或未经治疗的儿童。 包装供应/储存和搬运 供应 JIVI可作为一次性使用的玻璃瓶,每瓶一瓶冻干粉末。供应无菌瓶。 适配器15微米过滤器和预填充稀释剂玻璃桶注射器,共同作为无针重建系统。预填充稀释剂注射器含有灭菌注射用水,美国药典。行政机关也是在包装中提供。可用尺寸: 名词性强度(IU) 稀释剂(毫升) KIT NDC数 色码 500 2.5 0026-3942-25 Green 1000 2.5 0026-3944-25 Red 2000 2.5 0026-3946-25 Yellow 3000 2.5 0026-3948-25 Gray 在每个JIVI小瓶的标签上注明了IU中的实际因子VIII活性。 产品瓶和稀释剂注射器不是用天然胶乳制成的。 储运 产品包装出售 将JiVi在+2°C至+8°C(36°F至46°F)存储,从制造日期起最多24个月。不要冻僵。在此期间,JiVi可以在长达25°C或77°F的温度下储存长达6个月的单周期。 记录未打开的产品纸箱室温储存的开始日期。一旦储存在室温下,不要将产品返回冰箱。然后,货架期在室温下储存6个月后或在产品瓶的有效期之后到期,以较早者为准。在瓶上注明的有效期后不要使用JIVI。 ●保护吉维免受极端光照,并在使用前将瓶子与冻干粉一起储存在纸箱中。 尽快管理重组的JIVI。如果你不立即管理重组后的JVI,那么在室温下储存不超过3小时。如果重组溶液为多云或有颗粒物质,则不使用JIVI。使用所提供的管理设置。 完整资料附件: 1):https://labeling.bayerhealthcare.com/html/products/pi/Jivi_PI.pdf 2):https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=f04e5bd5-d7e2-453b-a407-2616d81a695d
JIVI(antihemophilic factor[recombinant]PEGylated-aucl)lyophilized powder for solution, for intravenous use INDICATIONS Jivi antihemophilic factor (recombinant), PEGylated-aucl, is a recombinant DNA-derived, Factor VIII concentrate indicated for use in previously treated adults and adolescents (12 years of age and older) with hemophilia A (congenital Factor VIII deficiency) for: On-demand treatment and control of bleeding episodes Perioperative management of bleeding Routine prophylaxis to reduce the frequency of bleeding episodes Limitations of use: Jivi is not indicated for use in children less than 12 years of age due to a greater risk for hypersensitivity reactions. Jivi is not indicated for use in previously untreated patients (PUPs). Jivi is not indicated for the treatment of von Willebrand disease. IMPORTANT SAFETY INFORMATION Jivi is contraindicated in patients who have a history of hypersensitivity reactions to the active substance, polyethylene glycol (PEG), mouse or hamster proteins, or other constituents of the product. Hypersensitivity reactions, including severe allergic reactions, have occurred with Jivi. Monitor patients for hypersensitivity symptoms. Early signs of hypersensitivity reactions, which can progress to anaphylaxis, may include chest or throat tightness, dizziness, mild hypotension and nausea. If hypersensitivity reactions occur, immediately discontinue administration and initiate appropriate treatment. Jivi may contain trace amounts of mouse and hamster proteins. Patients treated with this product may develop hypersensitivity to these non-human mammalian proteins. Hypersensitivity reactions may also be related to antibodies against polyethylene glycol (PEG). Neutralizing antibody (inhibitor) formation can occur following administration of Jivi. Carefully monitor patients for the development of Factor VIII inhibitors, using appropriate clinical observations and laboratory tests. If expected plasma Factor VIII activity levels are not attained or if bleeding is not controlled as expected with administered dose, suspect the presence of an inhibitor (neutralizing antibody). A clinical immune response associated with IgM anti-PEG antibodies, manifested as symptoms of acute hypersensitivity and/or loss of drug effect, has been observed primarily in patients < 6 years of age. The symptoms of the clinical immune response were transient. Anti-PEG IgM titers decreased over time to undetectable levels. No immunoglobulin class switching was observed. In case of clinical suspicion of loss of drug effect, conduct testing for Factor VIII inhibitors and Factor VIII recovery. A low post-infusion Factor VIII level in the absence of detectable Factor VIII inhibitors indicates that loss of drug effect is likely due to anti-PEG antibodies. Discontinue Jivi and switch patients to a previously effective Factor VIII product. The most frequently (≥5%) reported adverse reactions in clinical trials in previously treated patients (PTPs) ≥12 years of age were headache, cough, nausea, and fever.
