本期看點

1. 單抗療法briquilimab在針對慢性自發性蕁麻疹患者開展的1b/2a期研究中表現亮眼，兩個單劑量隊列中有89%的患者達成完全緩解（CR）。

2. 噬菌體療法BX004用于治療囊性纖維化（CF）患者因銅綠假單胞菌引起的慢性肺部感染，在一項早期臨床試驗中與安慰劑相比顯著降低了細菌數量約500倍，無耐藥發生，同時有效保護了健康微生物組。

Briquilimab：公布1b/2a期臨床試驗數據

Jasper Therapeutics公司公布了其候選單抗briquilimab用于治療慢性自發性蕁麻疹的1b/2a期研究BEACON的初步數據。Briquilimab是一種非糖基化單克隆抗體，可通過靶向細胞表面受體c-Kit（也稱為CD117）以避免與干細胞因子結合，從而阻斷肥大細胞中的關鍵生存信號，造成細胞凋亡與耗竭，從而消除肥大細胞驅動疾病（如慢性蕁麻疹）中炎癥反應的潛在來源。

此次公布的結果顯示，briquilimab在240 mg和360 mg單劑量隊列中表現出深度且快速的疾病控制效果，兩組共9名受試者中有8人（89%）實現了CR，7人（78%）在第2周即達到臨床緩解。此外，在BEACON研究中完成治療并轉入開放標簽擴展研究、接受每8周180 mg劑量治療的受試者中，也顯示出強大的臨床療效：在第12周時，11名受試者中有8人（73%）達到了CR。安全性方面，研究期間未報告任何≥3級的治療相關不良事件。

BX004：公布1b/2a期臨床試驗數據

BiomX公司宣布，其噬菌體療法BX004的首個人體試驗結果已在學術期刊

Nature Communications

論文中的數據表明，在針對抗生素耐藥性銅綠假單胞菌感染的1b/2a期臨床試驗中，BX004的安全性和耐受性良好，在所有患者中和所有測試劑量水平下均未發生治療相關安全事件。與接受安慰劑治療的患者相比，接受BX004治療患者的細菌數量下降了2.7 log??（約500倍），且未出現耐藥現象，同時有效保護了患者的健康微生物組。該公司正在推進BX004的2b期臨床試驗，預計將于2026年第一季度獲得頂線結果。

Paxalisib：公布1b期聯合治療試驗中首例患者的數據

Kazia Therapeutics公司公布了一項1b期臨床試驗中首例患者的初步結果，該研究旨在評估其可穿越血腦屏障的在研口服PI3K/Akt/mTOR通路抑制劑paxalisib聯用帕博利珠單抗和標準化療的療效與安全性。該公司于2016年底從基因泰克（Genentech）獲得了paxalisib的許可。該療法此前已獲得多項資格，包括美國FDA授予的針對膠質母細胞瘤的孤兒藥資格和快速通道資格（FTD），針對攜帶PI3K通路突變、需聯合放療治療的實體瘤腦轉移適應癥的FTD，以及針對彌漫性內生性橋腦膠質瘤（DIPG）和非典型畸胎樣/橫紋肌樣腫瘤的孤兒藥資格與罕見兒科疾病認定。

此次公布的結果顯示，一名61歲、腫瘤已局部轉移至左肺上葉的三陰性乳腺癌女性患者在接受治療僅21天后，其循環腫瘤細胞（CTCs）減少了超過50%，且CTC細胞簇也顯著減少。這些早期臨床數據與此前公布的臨床前數據一致。

ELU42：IND申請獲得FDA許可

Eluciderm公司宣布，美國FDA已批準其針對新藥ELU42的IND申請，可開展一項針對糖尿病足潰瘍（DFUs）患者的1/2a期開放標簽研究，以評估ELU42的安全性和療效。ELU42是一款新型外用小分子Wnt通路調節劑，具有抑菌特性，旨在治療慢性開放性傷口。
