拜耳肺动脉高压药物Adempas获FDA批准

2013-10-11 tomato 生物谷

拜耳(Bayer)10月9日宣布,FDA已批准Adempas(riociguat)用于2种类型的肺动脉高压:a)用于肺动脉高压(PAH)成人患者(WHO分级I)的治疗,以提高运动能力、WHO功能分级、推迟临床恶化;b)用于不能手术或手术后持续性、复发性慢性阻塞性肺动脉高压(CTEPH)成人患者(WHO分级IV)的治疗CETPH的治疗,以提高运动能力和WHO功能分级。 Adempas是唯一一种获F

拜耳(Bayer)10月9日宣布,FDA已批准Adempas(riociguat)用于2种类型的肺动脉高压:

(a)用于肺动脉高压(PAH)成人患者(WHO分级I)的治疗,以提高运动能力、WHO功能分级、推迟临床恶化;

(b)用于不能手术或手术后持续性、复发性慢性阻塞性肺动脉高压(CTEPH)成人患者(WHO分级IV)的治疗CETPH的治疗,以提高运动能力和WHO功能分级。

Adempas是唯一一种获FDA批准可用于治疗2种类型肺动脉高压的药物,同时也是唯一一种获FDA批准用于不能手术或手术治疗后持续性/复发性CTEPH的治疗药物。上个月,加拿大卫生部批准Adempas用于CTEPH的治疗。

Adempas的获批,是基于2项随机、双盲、安慰剂对照、全球性III期研究CHEST-1和PATENT-1、以及CHEST-2和PATENT-2目前获得的的长期数据。这些研究分别调查了口服riociguat治疗CTEPH和PAH的有效性和安全性。2项III期研究CHEST-1和PATENT-1均达到了研究的主要终点,此外riociguat在横跨多个相关次要终点均表现出持续改善,同时耐受性良好。

PAH和CTEPH是2种罕见的、危及生命的肺动脉高压,其特点是肺动脉压力明显增加。

Riociguat是拜耳开发的首个新一类可溶性鸟苷酸环化酶(sGC)激动剂,能够直接刺激sGC,增强其对低水平一氧化氮(NO)的敏感度,该药开发用于治疗2种肺动脉高压——慢性血栓栓塞性肺动脉高压(CTEPH)和肺动脉高压(PAH),改善患者的运动能力,riociguat将以品牌名Adempas销售。

拜耳去年称,预计该药的销售峰值将超过5亿欧元(约合6.46亿美元)。汤姆森路透发布分析报告称,预计该药在2017年的销售将达到6.79亿美元,同时将对市面上来自Actelion和吉利德(Gilead)的药物构成潜在的威胁。

拜耳于2013年2月提交了riociguat的新药申请(NDA),并于2013年8月6日获得了FDA心血管和肾脏药物顾问委员会(CRDAC)建议批准的积极意见,同时FDA于2013年9月授予riociguat治疗PAH和CTEPH的2个孤儿药地位认定。此前,FDA也已授予riociguat新药申请(NDA)优先审查资格。
