询问 AI与欧洲和加拿大供应商就opaganib的大规模增产进行合作进一步加强制造能力和产能，为潜在的紧急用药申请获批做好准备
--
使用opaganib治疗新冠肺炎全球2/3期研究的患者招募在6个国家予以批准后迅速推进
--
在美国进行的opaganib治疗新冠肺炎2期研究即将完成患者招募，并于最近通过了独立委员会第二次审查
以色列特拉维夫和北卡罗来纳罗利, Oct. 15, 2020 (GLOBE NEWSWIRE) -- 特种生物制药企业RedHill Biopharma Ltd. （Nasdaq：RDHL）（以下称“RedHill”或“公司”）今天宣布与欧洲和加拿大的两家专业制药厂商合作以推进opaganib的生产。针对这种新药治疗重症新冠肺炎的全球范围2/3期研究和在美国进行的2期研究正在快速进行中。此次宣布的生产合作旨在支持潜在的紧急用途申请及随后的用药需求。
“鉴于我们关于opagnib治疗新冠肺炎2/3期研究开发计划的快速推进，我们正在与倍受信赖的优质合作伙伴合作，扩大opaganib的制造能力和产能，以满足全球紧急用药申请一旦获批后的用药需求，”RedHill公司研发部高级副总裁Reza Fathi博士表示。
Opaganib是一种首创的口服鞘氨醇激酶-2 (SK2) 选择性抑制剂，显示抗炎和抗病毒双重活性，靶向宿主细胞成分，因而有可能最大限度地降低耐药可能性。
针对新冠肺炎重症患者的opaganib后期开发项目包括：美国2期研究（NCT04414618），目前正在八个临床试验中心进行，患者招募已接近完成，并在最近通过了独立委员会的第二次审查，预计数据将在今年年底前公布；全球2/3期研究（NCT04467840），正在15个研究地点迅速开展患者招募，有望在年底前招募270名患者。两项研究均为将opaganib用于需住院治疗和辅助供氧的新冠肺炎重症患者的随机、双盲、平行、安慰剂对照型试验。
Opaganib表现出对导致新冠病毒的有效抗病毒活性，在人体肺支气管组织的体外模型中完全抑制病毒复制。
该公司正在与美国政府机构就可能提供的资金进行讨论，以支持opaganib作为紧急用药的潜在申请以及扩大生产规模方面取得的迅速进展。
关于Opaganib（ABC294640，Yeliva®）
Opaganib作为一种新型化学实体，是专有、首创口服鞘氨醇激酶-2 (SK2) 选择性抑制剂，显示抗炎和抗病毒双重活性，靶向宿主细胞成分，有可能最大限度地降低病毒耐药的可能性。Opaganib还显示出抗癌活性，并有可能针对多种肿瘤、病毒、炎症和肠道适应症。
opaganib获得了美国FDA针对治疗胆管癌的罕见病用药批准，目前正在进行晚期胆管癌2a期研究评估和前列腺癌2期研究评估。此外还有一项全球2/3期研究和一项美国2期研究正在对opaganib治疗新冠肺炎的效果进行评估。
临床前数据显示，opaganib同时具有抗炎和抗病毒活性，具有减少炎性肺部疾病（如肺炎）和减轻肺纤维化损害的潜力。Opaganib表现出对导致新冠病毒的有效抗病毒活性，在人体肺支气管组织的体外模型中完全抑制病毒复制。此外，临床前体内研究1表明，通过降低支气管肺泡灌洗液中IL-6和TNF-α的水平，opaganib可降低流感病毒感染的病死率，并改善铜绿假单胞菌诱发的肺损伤。
opaganib最初由美国Apogee Biotechnology Corp开发，并在多项研究中获得成功，包括肿瘤、炎症、胃肠道和放射防护模型的多项临床前研究、针对晚期实体肿瘤患者的一项1期临床研究和一项额外的多发性骨髓瘤1期研究。
根据一项同情用药计划，以色列一家领先医院的新冠肺炎患者（按世界卫生组织的等级分类）接受了opaganib治疗。这些首批使用opaganib的新冠肺炎重症患者的治疗数据已经公布2。治疗结果分析表明，与同一医院回顾性配对病例对照组的患者相比，接受opaganib同情用药治疗的患者在临床结果和炎症标志物方面均有显著获益。opaganib治疗组的所有患者都在呼吸室内空气且无需使用插管和呼吸机的情况下出院，而对应的病例对照组中有33%的患者需要插管和使用呼吸机。opaganib治疗组的鼻高流量氧疗脱离的中位时间减少到10天，而匹配病例对照组则为15天。
Opaganib的开发因美国联邦和州政府机构给予Apogee Biotechnology Corp.的拨款和合同而得到支持，相关机构包括NCI、BARDA、美国国防部和FDA罕见病药物开发办公室。
正在进行的各项opaganib研究已在www.ClinicalTrials.gov上注册，该网站是美国国家卫生研究院提供的一项网上服务，为公众提供了访问公共和私人支持的临床研究信息的途径。
