目前,公司圍繞HLX04-O在全球範圍內積極開展III期臨床研究,現已在美國、中國、澳大利亞和歐盟完成首例患者給藥,並獲得包括新加坡在內的多個國家和地區的臨床試驗許可。復宏漢霖將攜手億勝生物持續推動HLX04-O在全球的臨床階段研究,以期憑藉相關研究結果實現HLX04-O在中國、澳大利亞、歐盟和美國等全球多個國家和地區上市,成為首批獲得批准用於眼科相關疾病治療的貝伐珠單抗,惠及全球眾多眼科疾病患者。未來,復宏漢霖將始終以臨床數據為重,秉持「內外兼修」的開發策略,不斷拓展藥物形式,持續推進更多產品的臨床進程,打造更多更高效的治療方案。
年齡相關性黃斑變性(AMD)是造成老年人視力損害和不可逆失明的主要原因之一[1],根據世界衛生組織報告,全球約有3000萬AMD患者,每年約有50萬人因為AMD而致盲[2]。AMD致盲患者中,以脈絡膜新生血管(Choroidal neovascularization,CNV)為特徵的濕性年齡相關性黃斑變性(wAMD)比例高達90%。隨着老年人口比例的不斷上升,wAMD已經成為一個日益嚴重的社會醫學問題,存在着巨大的未滿足的臨床需求[3]。隨着眼底治療方法的突破與發展,抗VEGF藥物已成為wAMD的一線療法[4],貝伐珠單抗玻璃體注射治療wAMD的有效性和安全性也已在多項臨床研究中得到驗證[5-11]。
