简介：

近日，美国FDA已批准XGEVA(denosumab)的补充生物制剂许可证申请(sBLA)，扩大当前Xgeva预防实体瘤患者骨骼相关事件(SREs)的适应症，纳入多发性骨髓瘤(MM)患者。Xgeva是一种单克隆抗体药物，靶向结合RANK配体(RANKL)来抑制骨细胞(osteoclast)的形成、功能及生存，而骨细胞负责骨吸收，会破坏骨骼。骨骼并发症(例如：骨折，脊髓压迫)和放疗及骨骼手术，对于MM患者而言是灾难性的。由于许多患者会遭受肾功能损害，因此限制了其临床治疗选择。Xgeva具有独特的作用机制，能够有效预防多发性骨髓瘤患者的骨骼并发症，而且其疗效与患者肾功能状态无关，该药有望解决多发性骨髓瘤患者群体中远未满足的显著医疗需求。批准日期：2017年10月18日 公司：安进公司Xgeva(地诺单抗[denosumab])注射液，用于皮下注射美国最初批准：2010年最近的重大变化实体肿瘤的适应症和用法，多发性骨髓瘤和骨转移：01/2018警告和注意事项，治疗后高血钙症停药：06/2018警告和注意事项，多个椎骨骨折(MVF)治疗后停止：01/2018警告和注意事项，胚胎 - 胎儿毒性：01/2018作用机制Xgeva与RANKL结合，RANKL是一种跨膜或可溶性蛋白质，对破骨细胞的形成，功能和存活至关重要，破骨细胞是负责骨吸收的细胞，从而调节骨骼中钙的释放。由RANKL刺激的增加的破骨细胞活性是具有骨转移的实体瘤中骨病理的介质。类似地，骨的巨细胞瘤由表达RANKL的基质细胞和表达RANK受体的破骨细胞样巨细胞组成，并且通过RANK受体的信号传导有助于骨溶解和肿瘤生长。Xgeva阻止RANKL在破骨细胞，其前体和破骨细胞样巨细胞表面激活其受体RANK。 适应症：Xgeva是一种RANK配体(RANKL)抑制剂，适用于：预防多发性骨髓瘤患者和实体瘤骨转移患者的骨骼相关事件。治疗成人和骨骼成熟的青少年骨巨细胞瘤无法切除或手术切除可能导致严重的发病率。治疗双膦酸盐治疗难治性恶性肿瘤的高钙血症。 剂量和给药：Xgeva仅用于皮下途径，不应静脉内，肌肉内或皮内给药。 多发性骨髓瘤和实体肿瘤的骨转移：在上臂，大腿上部或腹部皮下注射，每4周施用120mg。 骨巨细胞瘤：在治疗第一个月的第8天和第15天，每4周施用120mg，另外施用120mg剂量。皮下注射在上臂，大腿上部或腹部。必要时给予钙和维生素D以治疗或预防低钙血症。 恶性高钙血症：在治疗的第一个月的第8天和第15天，每4周施用120mg，另外施用120mg剂量。皮下注射在上臂，大腿上部或腹部。 剂量形式：在单剂量小瓶中的120mg/1.7mL(70mg/mL)溶液 禁忌症：低钙血症已知临床上对Xgeva的超敏反应。相同的有效成分：接受Xgeva的患者不应服用Prolia®。可能发生包括过敏反应的过敏反应。如果发生临床显着反应，则永久停用。 注意事项： 低钙血症：Xgeva可引起严重的症状性低钙血症，并且已报道致命病例。在开始Xgeva之前纠正低钙血症。在治疗期间监测钙水平，特别是在开始治疗的第一周，并充分补充所有钙和维生素D患者。在接受Xgeva的患者中已经报道了颌骨坏死(ONJ)。在开始Xgeva之前进行口腔检查。监测症状。在使用Xgeva治疗期间避免使用侵入性牙科手术。 非典型股骨骨折：评估大腿或腹股沟疼痛患者，以排除股骨骨折。 骨巨细胞瘤患者和骨骼生长患者停用治疗后的高钙血症：监测患者高钙血症的体征和症状，并按临床情况进行治疗。 治疗中断后多发性椎体骨折(MVF)：停止Xgeva治疗时，评估患者椎体骨折的风险。 胚胎-胎儿毒性：可能导致胎儿伤害。告知女性对胎儿有潜在风险的生殖潜力并使用有效的避孕措施。 不良反应： 实体瘤的骨转移：最常见的不良反应(≥25%)是疲劳/虚弱，低磷血症和恶心。 多发性骨髓瘤：最常见的不良反应(≥10%)是腹泻，恶心，贫血，背痛，血小板减少，外周性水肿，低钙血症，上呼吸道感染，皮疹和头痛。 骨巨细胞瘤：最常见的不良反应(≥10%)是关节痛，头痛，恶心，背痛，疲劳和四肢疼痛。 恶性高钙血症：最常见的不良反应(> 20%)是恶心，呼吸困难，食欲减退，头痛，外周性水肿，呕吐，贫血，便秘和腹泻。 用于特定人群： 儿科患者：建议仅用于治疗骨巨细胞瘤的骨骼成熟青少年。 肾功能损害：肌酐清除率低于30mL/min或接受透析的患者存在低钙血症的风险。充分补充钙和维生素D. 包装：Xgeva采用单剂量小瓶供应。每箱120mg/1.7mL 1vial NDC 储存：将Xgeva存放在原装纸箱中2°C至8°C(36°F至46°F)的冰箱中。不要冻结。一旦从冰箱中取出，Xgeva不得暴露在高于25°C/77°F的温度或直射光下，必须在14天内使用。如果在14天内没有使用，请丢弃Xgeva。保护Xgeva免受直射光和热。避免剧烈摇晃Xgeva。 完整说明书资料附件：https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=628f0998-1206-4001-aeee-18133aa9f3bf
