NCT05003245為一項多中心、隨機、雙盲、陽性對照的非劣效III期臨床研究,,,,,,旨在比較HLX04-O與雷珠單抗玻璃體內注射(IVT)在濕性年齡相關性黃斑變性(wAMD)患者中的有用性和清静性。。。。。。入組的所有患者凭证1:1的比例隨機接受HLX04-O(1.25 mg)IVT或雷珠單抗(0.5 mg)IVT給藥,,,,,,每周围一次,,,,,,在患者未發生殒命、撤回知情赞成、失訪或申辦方終止研究的情況下,,,,,,持續治療一年。。。。。。本次研究的主要研究終點為第48周最佳矯正視力(BCVA)較基線改善的平均字母數變化,,,,,,次要研究終點為其他有用性、清静性、耐受性及藥代動力學指標。。。。。。研究結果顯示,,,,,,HLX04-O組第48周BCVA較基線改善的平均字母數變化結果非劣於雷珠單抗組,,,,,,達到主要研究終點。。。。。。别的,,,,,,HLX04-O和雷珠單抗對wAMD患者人群整體、眼部、非眼部的清静性特徵均相似,,,,,,且清静性优异。。。。。。

HLX04-O是復宏漢霖使用基因工程技術構建的一款重組抗VEGF人源化單克隆抗體注射液,,,,,,能夠特異性結合VEGF,,,,,,阻斷VEGF與內皮細胞上的受體Flt1(VEGFR-1)和KDR(VEGFR-2)結合,,,,,,抑制其酪氨酸激酶信號通路的激活,,,,,,進而抑制內皮細胞增生,,,,,,減少新生血管天生,,,,,,從而實現對wAMD等血管增生眼部疾病的治療。。。。。。根據眼科用藥需求,,,,,,公司在貝伐珠單抗漢貝泰®的基礎上坚持活性因素不變,,,,,,對處方、包裝质料、規格和生產工藝等進行優化,,,,,,開發了新的眼科製劑產品HLX04-O。。。。。。??杀刃匝芯颗⑸a工藝和製劑處方的變更對藥物製劑的質量、清静性和有用性未產生倒运影響。。。。。。
除NCT05003245外,,,,,,公司亦就HLX04-O同步開展了一項國際多中心III期臨床研究(NCT04740671),,,,,,並在中國、澳大利亞、歐盟和美國等國家和地區入組受試者。。。。。。未來,,,,,,復宏漢霖也將積極推動創新生物藥品的開發,,,,,,持續高效地為全球患者提供可負擔的、高效的治療计划。。。。。。
關於濕性年齡相關性黃斑變性
年齡相關性黃斑變性(AMD)是造成晚年人視力損害和不可逆失明的主要缘故原由之一[1],,,,,,根據天下衛生組織報告,,,,,,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(CNV)為特徵的濕性年齡相關性黃斑變性(wAMD)比例高達90%。。。。。。隨着晚年生齿比例的不斷上升,,,,,,wAMD已經成為一個日益嚴重的社會醫學問題,,,,,,保存着重大的未滿足的臨床需求[3]。。。。。。隨着眼底治療要领的突破與發展,,,,,,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的有用性和清静性也已在多項臨床研究中获得驗證[5-11]。。。。。。
