RedHill Biopharma 獲准在俄羅斯進行第 2/3 期 COVID-19 研究

當英國最近批准並在意大利提交類似申請後,俄羅斯批准將 opaganib 用於嚴重 COVID-19 患者以進行第 2/3 期研究的臨床試驗申請
--
第 2/3 研究旨在從多達 40 個臨床中心納入 270 名受試者;計劃納入工作將在本月稍後啟動,並計劃於 2020 年第四季提交緊急使用授權申請
--
同時,美國第 2a 期將 opaganib 用於嚴重 COVID-19 的研究正在迅速拓展,現已納入超過 25% 患者
--
將 opaganib 在以色列用於多達 50 名嚴重 COVID-19 患者的臨床研究也已獲得核准
--
與匹配病例對照組相比,根據恩慈使用的嚴重 COVID-19 患者治療結果顯示可對此類患者帶來實益

以色列特拉維夫和北卡羅萊納州拉里格, July 20, 2020 (GLOBE NEWSWIRE) -- RedHill Biopharma Ltd. (Nasdaq: RDHL)(簡稱 RedHill 或「該公司」),是一家專門生物製藥公司,今天宣佈從俄羅斯聯邦衛生部獲批取得臨床試驗授權 (CTA) 申請以進行第 2/3 研究,以評估將 opaganib (Yeliva®, ABC294640)1 用於嚴重 SARS-CoV-2 感染(COVID-19 病因)及肺炎的住院患者。研究最近也已在英國獲准,另外在意大利進行類似的審核申請,目前正在計劃將研究進一步擴展到其他國家。

RedHill 的首席營運主管 Gilead Raday 說:「我們現正使用 opaganib 快速促進 COVID-19 的臨床開發計劃,如取得成功,我們計劃在今年第四季提交緊急使用授權申請。將 opaganib 用於嚴重 COVID-19 患者的第 2/3 期研究已在兩個國家的監管機關獲得核准,而我們正在將研究擴展至其他國家。由於計劃於本月稍後將啟動第 2/3 期研究,考慮到美國第 2a 期研究的納入率超過 25%,RedHill 在相關競爭中處於有利位置,為 COVID-19 住院患者帶來新的潛在實益療法。」  

這項多中心、隨機、雙盲、平行組、安慰劑對照的第 2/3 期研究旨在納入多達 270 名需要住院和補充氧氣治療的嚴重 COVID-19 肺炎患者。受試者將以 1:1 的比例隨機分配接受 opaganib 或安慰劑,加上標準護理。研究的主要終點是在第 14 天之前評估需要插喉和機械呼吸的患者比例。在評估大約 100 名受試者的主要終點時,獨立的數據安全監控委員會 (DSMB) 將進行僅揭盲徒勞中期分析。

該公司亦宣佈經已獲得以色列衛生部批准開展一項研究,以評估將 opaganib 用於多達 50 名嚴重 COVID-19 感染和肺炎的患者。

在一項將 opaganib 用於隨機、雙盲、安慰劑對照的第 2a 期臨床研究中,美國目前也正在進行納入 (NCT04414618)。該研究旨在納入多達 40 名需要住院治療和補充氧氣的嚴重 COVID-19 肺炎患者。此臨床試驗並無統計學意義。

RedHill 最近宣佈,將 opaganib 用於治療嚴重 COVID-19 患者的治療結果經已發佈2。對 5 名嚴重 COVID-19 患者的治療結果進行的分析表示,與同一醫院的回顧性配對病例對照組相比,在恩慈使用 opaganib 治療的患者中,臨床結果和發炎標記均獲得實益。Opaganib 治療組的所有患者均無需機械呼吸即可出院,而匹配病例對照組的 33% 則需要機械呼吸。在 opaganib 治療組中,從高流量鼻導管戒斷的中位時間減少至 10 天,而配對病例對照組則為 15 天。

關於 Opaganib (ABC294640, Yeliva®)
Opaganib 是新的化學實體,是一種專利的頂級口服鞘氨醇激酶-2 (SK2) 選擇性抑制劑,適應症為抗癌、抗炎和抗病毒活性,及針對多種腫瘤、病毒、發炎和腸胃問題。透過抑制 SK2,opaganib 可影響與癌症生長、病毒複製和病理發炎相關的多種細胞途徑。

Opaganib 原本由總部位於美國的 Apogee Biotechnology Corp. 開發,至今已完成多項成功的臨床前研究,當中涉及腫瘤學、發炎、腸胃道和放射防護模型,以及針對患有晚期實體瘤癌症患者的第 1 期臨床研究。

Opaganib 獲得美國 FDA 用於治療膽管癌的孤兒藥稱號,目前正在晚期膽管癌的第 2a 期研究和前列腺癌第 2 期研究中接受評估。Opaganib 現在也被評估用於治療冠狀病毒 (COVID-19)。

臨床前數據表示,opaganib 具有抗炎和抗病毒活性,並具有減輕肺部發炎疾病(如肺炎)和減輕肺纖維化損害的潛力。早前的一些臨床前研究支持 SK2 在類似冠狀病毒的正向單鏈 RNA 病毒的複制轉錄複合物中的潛在作用,而其抑制作用可能可抑制病毒複製。臨床前的體內研究3已顯示 opaganib 透過降低支氣管肺泡灌洗液中的 IL-6 及 TNF-alpha 水平,成功降低流感病毒感染的死亡率,同時改善銅綠假單胞菌 (Pseudomonas aeruginosa) 誘導的肺損傷。

Opaganib 的開發已獲得美國聯邦和州政府機構授予 Apogee Biotechnology Corp. 的贈款和合約支持,其中包括 NCI、BARDA、美國國防部和 FDA 孤兒藥品開發辦公室。
