使蛋白尿下降超80%的腎病療法；緩解率優于標準療法的抗癌免疫聯合治療…… | 一周盤點

本期看點

1. 用于治療腎病的 在研藥物povetacicept在早期臨床研究中表 現亮眼， 48周數據顯示，IgA腎病 （IgAN）患者 中蛋白尿較基線下降64%， 原發性膜性腎病 （pMN）患者的 蛋白尿較基線下降82%， 且兩種疾病的 估算腎小球濾過率（eGFR） 均保持 穩定。

2. α/β-IL-2受體偏向性部分激動劑 STK-01 2與標準治療方案聯用，一線治療PD-L1陰性非鱗狀非小細胞肺癌（NSCLC）患者的早期臨床試驗數據積極， PD-L1陰性患者的客觀緩解率（ORR）為53%，與標準治療方案23-32%的歷史緩解率相比具有優勢。

Povetacicept：公布1/2期臨床試驗的新數據

Vertex Pharmaceuticals公司公布了其在研藥物povetacicept（pove）在IgA腎病和原發性膜性腎病中的48周最新數據。Povetacicept是一種高效BAFF（B細胞激活因子）和APRIL（一種增殖誘導配體）的雙重拮抗劑，是一款經改造TACI結構域變體的Fc融合體。BAFF與APRIL細胞因子因其在B細胞（特別是抗體分泌細胞）、T細胞和先天免疫細胞中的激活、分化和/或生存所扮演的角色，在多種自身免疫性疾病的發病機制中發揮關鍵作用。憑借其工程化的TACI結構域，pove在臨床前研究中展現出優于其他同類抑制劑的結合親和力、效力和組織穿透能力。目前，該藥已獲美國FDA授予pMN適應癥的快速通道資格，并計劃啟動生物制品許可申請的滾動提交以爭取加速批準。

在IgAN患者中（n=21），接受每4周一次80 mg劑量pove皮下給藥48周后，平均24小時尿蛋白肌酐比（UPCR）較基線下降64%，eGFR保持穩定，90%的患者實現血尿緩解，53%達到臨床緩解（定義為UPCR<0.5 g/g、血尿陰性且eGFR較基線降低<25%）。在pMN患者中（n=10），平均24小時UPCR降幅達82%，eGFR同樣穩定，40%患者實現完全臨床緩解（UPCR<0.5 g/g）。Pove總體安全性和耐受性良好，不良事件多為輕中度，沒有發生嚴重不良事件，安全性特征在兩個疾病隊列中相似。

STK-012：公布1a/1b期聯合治療試驗的初步數據

Synthekine公司公布了其在研藥物STK-012與標準治療方案（pembrolizumab聯合化療）聯用，一線治療PD-L1陰性非鱗狀非小細胞肺癌患者的早期臨床試驗數據。STK-012是一種潛在“first-in-class”的α/β-IL-2受體偏向性部分激動劑，旨在選擇性激活抗原特異性T細胞以增強抗腫瘤免疫反應，并避免對其他淋巴細胞的廣泛刺激，例如與IL-2毒性相關的自然殺傷（NK）細胞。

此次公布的結果顯示，STK-012聯合療法顯示出良好的安全性和有效性，無明顯IL-2毒性。在25名安全性可評估的受試者中，最常見的治療相關不良事件（TRAE）是可控制且可逆的惡心、疲勞和皮疹/皮炎。沒有受試者因TRAE而停止STK-012治療。在21例療效可評估的患者中，STK-012聯合標準治療展現出優于歷史對照的抗腫瘤活性：PD-L1<1%患者的整體ORR達53%，遠高于既往PD-L1陰性患者接受標準治療方案23–32%的緩解率。值得注意的是，在10例攜帶

APG333：公布1期臨床試驗的中期數據

Apogee Therapeutics公司公布了其在研藥物APG333的首次人體1期試驗的中期數據。APG333是一種具有延長半衰期的新型單克隆抗體，靶向一種上皮細胞來源的細胞因子TSLP，該細胞因子在促進免疫細胞募集和激活方面發揮著重要作用，已被臨床驗證為治療哮喘等炎癥性疾病的有效靶點。

此次公布的數據顯示，APG333在所有隊列中均耐受性良好，劑量高達1000 mg。APG333的半衰期約為55天，單次給藥后可持續抑制關鍵炎癥生物標志物長達6個月，顯著超出試驗預設目標，有望支持每3個月或6個月一次的給藥方案。此外，由于TSLP抑制劑可與其他單抗聯用以擴大療效人群，Apogee公司計劃將APG333與其另一候選藥物APG777聯合開發為復方制劑（APG273），用于呼吸道疾病，目標實現每季度一次甚至更少頻次的給藥。
