以色列特拉維夫和北卡羅萊納州拉里格, Oct. 15, 2020 (GLOBE NEWSWIRE) -- RedHill Biopharma Ltd. (Nasdaq: RDHL)(「RedHill 」或「公司」)是一家專門生物製藥公司,今天宣佈與歐洲和加拿大的兩家專業製藥公司合作,以加速生產 opaganib,從而支持緊急使用授權申請和後續需求,而使用該藥物治療嚴重 COVID-19 肺炎的全球第 2/3 期和美國第 2 期研究正在快速進展。

RedHill 研發部高級副總裁 Reza Fathi 博士說:「鑑於使用 opaganib 治療 COVID-19 的第 2/3 期研究快速進展,我們現正與可信賴的優質合作夥伴擴大 opaganib 的製造能力和產能,以滿足獲得全球緊急使用授權後可能出現的需求。」

Opaganib 是一種一流的口服鞘氨醇激酶-2 (SK2) 選擇性抑制劑,展示出抗炎及抗病毒活性雙重作用,可針對宿主細胞成分,有可能盡量降低病毒抗藥性的可能性。

使用 opaganib 治療嚴重 COVID-19 肺炎患者的後期開發計劃包括:美國第 2 期研究 (NCT04414618) 正在於 8 個臨床試驗點持續進行,即將完成納入程序,且最近通過第二次獨立委員會審查,預計將在今年年底前發佈數據。此外,全球第 2/3 期研究 (NCT04467840),目前正在透過 15 個研究中心快速納入患者,並有望在今年年底前納入多達 270 名患者。這兩項研究都是隨機、雙盲、平行組、安慰劑對照試驗,讓需要住院和補充氧氣治療的嚴重 COVID-19 肺炎患者使用 opaganib。

Opaganib 對 SARS-CoV-2 表現出有效的抗病毒活性,該病毒導致 COVID-19,在人類肺支氣管組織體外模型中完全抑制病毒複製。

公司正在與美國政府機構討論潛在資金,以支持 opaganib 快速促進潛在的緊急使用授權及加大生產規模。

關於 Opaganib (ABC294640, Yeliva®)
Opaganib 是全新的化學實體,是一種專有、一流的口服鞘氨醇激酶-2 (SK2) 選擇性抑制劑,展示出抗炎及抗病毒活性雙重作用,可針對宿主細胞成分,有可能盡量降低抗藥性的可能性。Opaganib 也表現出抗癌活性,並有可能針對多種腫瘤學、病毒、發炎及腸胃疾病。

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 2 期研究和前列腺癌第 2 期研究中接受評估。Opaganib 目前正在全球第 2/3 期及美國第 2 期研究中接受用於治療 COVID-19 患者的評估。

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。Opaganib 對 SARS-CoV-2 表現出有效的抗病毒活性,該病毒導致 COVID-19,在人類肺支氣管組織體外模型中完全抑制病毒複製。 此外,臨床前的體內研究1 已顯示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 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腫瘤癌症患者的第 1 期臨床研究,以及另一項第 1 期的多發性骨髓瘤研究。

在一項恩慈使用計劃下,以色列一所領先醫院使用 opaganib 治療 COVID-19 患者(根據世衛序號量表分類)。最近宣佈經已發佈將 opaganib 用於治療嚴重 COVID-19 患者的治療數據2。治療結果的分析顯示,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 治療組的所有自主呼吸患者均無需插喉或機械呼吸即可出院,而匹配病例對照組的 33% 則需要插喉或機械呼吸。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。

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。

Opaganib 的持續研究在 www.ClinicalTrials.gov 註冊,這是美國國家衛生研究院的網上服務,為公眾提供有關公開和私人支持的臨床研究資訊。
