强生拜瑞妥(Xarelto)ACS适应症遭FDA拒绝

强生(JNJ)和拜耳(Bayer)2月14日表示,FDA已拒绝了抗凝血剂拜瑞妥(Xarelto)用于急性冠脉综合征(ACS)的新适应症申请。这已是FDA第三次拒绝批准Xarelto用于ACS适应症。

强生最初于2011年底提交了Xarelto用于ACS治疗的适应症申请,但遭FDA拒绝,FDA称疗效数据并没有强大到足以支持该适应症的获批。随后,强生提交了额外的数据,但遭FDA再度拒绝。

在强生第3次提交Xarelto ACS适应症申请后,FDA内部最新审查表明,该机构对强生分析相关临床数据的方法持怀疑态度,并表示没有令人信服的证据来证明Xarelto能够提供显著的临床利益或填补未获满足的医疗需求,因为市场上还有其他药物。而FDA顾问委员会于2014年1月举行会议并投票表决,认为不应批准Xarelto用于ACS适应症,该委员会认为,强生所提交的额外数据,并没有改变他们的看法,Xarelto所显示出的临床利益,并没有超过其升高的出血风险。该委员会还表示,从整体临床数据中摘取出一段为期90天的时间框架,并对药物的安全性或疗效下确定性的结论,是不可取的。

当被问及FDA是否已要求开展新的临床试验或其他数据时,强生发言人Kristina Chang拒绝置评。

目前,Xarelto已获批用于治疗和预防深静脉血栓和肺动脉栓塞,同时获批用于并非由心脏问题引发的不规则心脏跳动患者,以降低中风风险和减少血液凝块。现在,强生希望FDA批准Xarelto用于急性冠脉综合征(ACS)。
