将HIV治疗从每年给药365天变为12次,长效cabotegravir/rilpivirine即将问世

1.2019年3月

专注开发HIV/AIDS药物的ViiV Healthcare公布了新型长效注射HIV疗法(cabotegravir/rilpivirine,CAB/RPV)(每月一次肌肉注射给药)关键III期临床研究FLAIR(临床登记号:NCT02938520),ATLAS (NCT02951052)的48周数据。

2019年CROI会议上公布的FLAIR相关数据显示:cabotegravir/rilpivirine与HIV复方药Triumeq(abacavir/dolutegravir/lamivudine,ABC/DTG/3TC)(多替拉韦/阿巴卡韦/拉米夫定)相比,CAB/RPV在维持HIV-1成人感染者病毒学抑制方面具有非劣效性(病毒学抑制率)。

FLAIR临床研究针对HIV-1初治患者,最开始需要接受DTG/ABC/3TC口服方案诱导治疗20周。在16周时HIV-1 RNA<50拷贝/毫升患者按照1:1比例分为针剂组和继续口服方案组,48周时病毒学无应答率,HIV-1 RNA≥50拷贝/毫升的患者比例针剂组非劣效于口服方案组(2.1% vs 2.5%);病毒学抑制率,HIV-1 RNA<50拷贝/毫升的患者比例针剂组非劣效于口服方案组(93.6% vs 93.3%)(265/283 vs 264/283)。

双药长效注射制剂,每月一次:cabotegravir长效制剂(CAB LA)为一款新型整合酶抑制剂(长效纳米混悬液, long-acting nanoformulated)(integrase inhibitor ),rilpivirine长效制剂(RPV LA)为非核苷类逆转录酶抑制剂(non-nucleoside reverse transcriptase inhibitor  )。两个单独的肌内注射药物,臀部是首选的注射部位。


2.2019年4月

ViiV Healthcare向美国FDA递交新型长效注射HIV疗法(cabotegravir/rilpivirine)新药上市申请(NDA)。

 

3.2019年6月

美国FDA授予cabotegravir/rilpivirine新药上市申请(NDA)优先审评(Priority Review)资格。这一操作,将使原本常规审评时间10个月,缩短为6个月。批准日期预计在2019年12月29日。如果本款疗法获批,将HIV治疗从每年给药365天变为12次,大大提高患者的依从性。
