(2019年10月15日,北京)强生公司在华制药子公司西安杨森制药有限公司今日宣布,旗下全球首个CD38单克隆抗体靶向药物兆珂®(达雷妥尤单抗注射液)在中国上市,用于单药治疗复发和难治性多发性骨髓瘤成年患者,患者既往接受过包括蛋白酶体抑制剂和免疫调节剂的治疗且最后一次治疗时出现疾病进展。

多发性骨髓瘤(Multiple Myeloma, MM)是一种不可治愈的血液系统恶性肿瘤,原发于骨髓,其特征为恶性浆细胞异常增生。首都医科大学附属北京朝阳医院血液与肿瘤科主任陈文明教授指出:“我国每年有27,800例新发的多发性骨髓瘤病例,发病率已超过急性白血病,位居血液系统恶性肿瘤第二位。尽管近年来多发性骨髓瘤的治疗取得了诸多进展,现有的治疗药物包括蛋白酶体抑制剂、免疫调节剂等,但多数患者仍面临着复发或耐药的问题,预后情况不容乐观。” 研究显示,多发性骨髓瘤患者的长期生存与能否获得高质量的缓解密切相关。现有治疗方案治疗复发和难治性多发性骨髓瘤完全缓解率(≥CR)不理想,其中位总生存期仅有9个月。

除疾病本身的复杂性之外,患者及家属对于多发性骨髓瘤的认知也严重不足,缺乏系统性的教育和获得权威可靠信息的途径,往往容易忽视早期的疾病信号。而随着病症的加重,生理和心理上的双重痛苦愈发影响患者的治疗信心。

“那些正在经历复发或对现有治疗方案产生耐药的患者,包括他们的家人,在生理和心理上都承受着沉重的负担。因此,他们对作用机制不同且耐受性更佳的新型治疗药物有着非常强烈的渴望。”患者组织骨髓瘤之家创始人洪飞表示。

兆珂®是全球及国内首个获批的靶向作用于CD38的全人源单克隆抗体。无论在哪个疾病阶段,CD38是在所有患者的多发性骨髓瘤细胞上均会高表达的蛋白。兆珂®拥有独特的双重机制,一方面可直接与CD38结合,通过多重机制诱导骨髓瘤细胞死亡,达到快速缓解;另一方面通过调节免疫微环境,激活免疫细胞CD8+毒性T细胞和CD4+辅助T细胞,持续促进骨髓瘤细胞死亡。

北京大学第三医院血液科主任景红梅教授表示:“多发性骨髓瘤的最终治疗目标是长期生存。具有创新双重机制的达雷妥尤单抗的到来为患者实现更深缓解、更长生存提供了更好的治疗选择,有望再定义国内多发性骨髓瘤的治疗。虽然多发性骨髓瘤目前尚不能治愈,但是如果有创新治疗方案的出现,最终使患者与非多发性骨髓瘤人群的预期寿命相等,其实这就意味着多发性骨髓瘤患者在功能上已经实现了治愈。”

西安杨森医学事务部负责人李滨介绍:“作为国内首个获批的针对多发性骨髓瘤的CD-38单克隆抗体靶向药物,兆珂®的显著疗效和安全性已在国际和国内临床试验中得到充分证实,为国内复发难治性多发性骨髓瘤患者提供了一项拥有全新作用机制的、安全有效的治疗选择。”

两项国际临床研究汇总分析结果显示,既往接受过多线治疗的多发性骨髓瘤患者使用16mg/kg达雷妥尤单抗单药治疗,中位总生存期延长至20个月,83%患者最佳疗效评估为疾病稳定或更好,总缓解率为31%。中国的临床研究结果显示,兆珂®单药用于既往接受至少2线治疗的复发或难治性多发性骨髓瘤中国患者的临床疗效、安全性与全球临床研究基本一致。

“在杨森,我们致力于‘创造一个没有多发性骨髓瘤的未来’并为此而不懈努力。兆珂®的到来让焦急等待新疗法的复发和难治性多发性骨髓瘤患者及其家庭重新拥有新的希望,帮助患者延长生存期,改善生存质量。”西安杨森总裁Asgar Rangoonwala强调,“患者仍未被满足的治疗需求始终是我们关注的重点,在加快引入创新药物的同时,我们希望与政府、医疗机构、患者组织等多方力量合作,不断提升药物可及性,使创新真正到达并造福中国患者,为实现‘健康中国2030’规划添砖加瓦。”

目前,兆珂®已进入中国,覆盖北京、上海、广州、杭州等城市。中国癌症基金会已正式启动兆珂患者援助项目,帮助患者改善治疗现状,获得更长的生存时间,提升多发性骨髓瘤患者生活质量。

根据Fox Chase癌症中心的最新研究,免疫刺激性单克隆抗体Elotuzumab能够促进独特的SLAMF7-SLAMF7相互作用,以促进对多发性骨髓瘤癌细胞的细胞毒性。Elotuzumab联合来那度胺和地塞米松被批准用于治疗复发或难治性多发性骨髓瘤患者。该药物结合信号传导淋巴细胞活化分子家族成员7(SLAMF7),这是一种在骨髓瘤细胞表面高度表达的蛋白质。先前的研究表明,Elotuzumab通过

以腰腿痛为首发症状的多发性骨髓瘤

多发性骨髓瘤(multiple myeloma,MM)是一种浆细胞恶性增殖性疾病,属于血液科诊治范畴,占血液系统肿瘤10%,病变常累及肋骨、胸椎、腰椎、骨盆等骨骼。由于相应骨骼的疼痛,MM病人常首诊于骨科或疼痛科。如果病变累及腰椎,往往出现腰腿痛,常需与腰椎间盘突出症、骨质疏松症、腰臀部软组织损伤和风湿性疾病等相鉴别诊断。由于多发性骨髓瘤的临床表现复杂,容易与上述这些疾病相混淆,可能发生漏诊或误诊

多发性骨髓瘤患者腰椎间盘突出重吸收1例

患者,男,42岁,因腰痛2个月、左下肢放射痛1月余来我院就诊。查体:疼痛沿L5神经根分布,左下肢腓肠肌外侧麻木,足部感觉无异常。左侧直腿抬高试验30°(+),加强试验(+)。双侧膝腱及跟腱反射正常,病理征阴性。腰椎MRI检查显示:T2像中L4~5椎间盘退变膨出,L5~S1椎间盘向左后突出,压迫L5神经根(见图1A、B)。行按摩、理疗、药物等非手术治疗2个月后症状缓解,遂未再就诊。6个月后患者腰痛复

硼替佐米治疗多发性骨髓瘤骨病1例

患者王某,女,59岁,因“腰部疼痛伴活动受限40余天。”来本院骨科住院治疗。患者于2017年10月无明显诱因出现腰部疼痛,活动受限,行走困难。于当地医院行腰部X线片示:L1椎体压缩骨折,给予理疗治疗效果欠佳。患者腰背部疼痛加重,活动受限,卧床翻身及坐立起身困难。2017年11月22日来我院骨科住院治疗,查生化示β2-微球蛋白、肌酐偏高,球蛋白正常;腰椎MRI示:胸腰骶椎多椎体及其附件异常改变,考虑
