Abstract
本發明涉及一種雙功能血管抑制劑,其具有VEGF抑制活性和FGF抑制活性,能夠抑制VEGF和FGF雙因數或者高糖誘導的細胞增殖、細胞遷移和/或管腔成形。本發明還涉及該雙功能血管抑制劑抑制視網膜血管生成的用途,如糖尿病視網膜病變,年齡相關黃斑變性等。
Description
本發明涉及一種雙功能血管生成抑制劑及其用途,具體涉及一種具有VEGF抑制活性和FGF抑制活性的融合蛋白及其在抑制VEGF和FGF雙因數或者高糖誘導的細胞增殖、細胞遷移和/或管腔成形中的用途,如抑制視網膜血管生成血管新生相關眼部疾病,糖尿病視網膜病變,年齡相關黃斑變性等。
眼底新生血管是多種眼部疾病的嚴重併發症,新生血管可以在角膜、虹膜睫狀體、脈絡膜、視網膜、黃斑及視訊光碟等幾乎眼內所有組織中出現,它能夠引起這些部位的組織出血、滲出及增生等一系列病理改變,因而造成眼球結構和功能的破壞,嚴重損害視功能。這一系列的眼底病變包括糖尿病視網膜病變(diabetic retinopathy,DR)、早產兒視網膜病(retinopathy ofprematurity,ROP)、年齡相關性黃斑變性(age-related macular degeneration,AMD)等,嚴重影響視力,甚至致盲。
研究表明,VEGF是目前所知對血管新生最特異、最有效的生長因數。1990年代以來,以VEGF為靶標,通過阻斷VEGF信號通路
抑制眼底血管新生的藥物成為開發的熱點。蘭尼單抗(Ranibizumab,商品名Lucentis)可特異性地結合VEGF-A,已獲美國FDA批准用於治療濕性老年黃斑變性和糖尿病性黃斑水腫。VEGF Trap-Eye(阿柏西普或Eylea)是美國Regeneron製藥公司開發的抗VEGF重組蛋白,臨床研究結果顯示對DME(糖尿病性黃斑水腫)的療效令人滿意,已遞交治療DME補充申請。KH902(康柏西普,Conbercept)是成都康弘公司開發的針對老年黃斑變性(AMD)的VEGFR-Fc重組蛋白,2013年12月批准上市用於治療AMD。以VEGF為靶標的雷珠單抗等成功用於DR的臨床研究和臨床應用中表明VEGF是DR的主要有效靶標之一。
儘管針對VEGF靶標的藥物在臨床上取得了很大的進展,由於血管新生受多種因數的調節,血管新生的調控是一個十分複雜的動態平衡過程。現有的藥物在臨床治療中也存在很大的局限性,因此如何進一步提高抗血管新生的臨床治療效果是研究者需要解決的問題,也是研究開發下一代抗血管新生藥物的重點。
成纖維細胞生長因數(FGF)是一種結合肝素的生長因數家族,其在多種生物學功能上具有重要作用,例如細胞增殖、分化、遷移、血管新生和腫瘤發生。其通過結合並活化細胞表面FGF受體(FGFR)發揮其多種生物學功能。成纖維細胞生長因數受體(fibroblast growth factor receptor,FGFR)是與成纖維細胞生長因數(FGF)家族成員相結合的受體,其一部分參與疾病過程。
申請人在專利CN201110131029.X公開了一種靶向VEGF和FGF的雙特異性融合蛋白(專利CN 201110131029.X的28#融合蛋白,
以下簡稱VF28),研究結果表明VF28融合蛋白具有良好的生物學活性,能夠有效的靶向VEGF和FGF靶點,在治療或預防腫瘤和/或眼科血管新生性疾病方面有顯著的療效。但是,在研究過程中發現,製備的VF28隨著保存時間的延長存在活性不穩定的問題,在開展的3批次VF28原液長期試驗中(-80℃±10℃長期試驗條件),放置0時、1個月、3個月、6個月,進行結合活性(ELISA法)分析,資料顯示,在1個月、3個月、6個月各監測時間點分別有1批次、2批次、3批次VF28原液結合活性檢測結果不符合評價標準要求(FGF端的結合活性不符合導致);在開展的3批VF28成品加速試驗條件穩定性試驗中,25℃±2℃加速試驗條件下放置1個月,進行細胞活性分析。結果顯示:三個批次中有一個批次的VF28成品細胞活性檢測結果超出評價標準要求,不符合評價標準要求。
針對上述問題,本發明提供了一種改構的、靶向VEGF和FGF的雙功能血管生成抑制劑RC28-05,其不僅具有良好的生物學活性,能夠有效的抑制視網膜血管生成,在諸如糖尿病視網膜病變,年齡相關黃斑變性等眼部疾病中有顯著的療效,並且製備的產品保存穩定,不易降解,對儲藏溫度、環境等要求較低。

4)將收集的全部洗脫液再進行陰離子交換層析去除少量聚體、CHO宿主細胞蛋白、宿主DNA和細胞內毒素等;
5)收集上述層析後的穿透液,再進行納米膜過濾去除非脂包膜類病毒;

7)成品製備:1000支規格為40mg/mL(0.2ml/支)的成品的製備方法如下,測定上述蛋白原液中RC28-05蛋白的濃度,定義為C mg/mL,考慮到10%的灌裝損耗,總計需要配製220ml蛋白液。則需要的總蛋白量為
220ml*40mg/mL*0.2ml=8.8g蛋白。則需要使用蛋的白原液體積為V=8.8/C*1000(mL),取V mL蛋白原液,向其中加入緩衝液(0.02mol/L磷酸二氫鈉、0.015mol/L氯化鈉、0.2mol/L蔗糖、0.02%(W/V)聚山梨酯80)至220mL,混合均勻,用孔徑不大於0.22μm的濾膜過濾除菌,分裝、軋鋁蓋、裝盒後,即為RC28-05成品。
