PIN-5018:1期臨床試驗完成首例患者給藥
![]()
Pin Therapeutics公司宣布,其基于公司提出的創新機制“p53合成激活”開發的口服CK1α選擇性降解劑PIN-5018,已在1期臨床試驗中完成首例患者給藥。該患者罹患腺樣囊性癌(ACC),這是一種罕見且治療選擇有限的惡性腫瘤。在兩個患者來源異種移植(PDX)ACC模型中,PIN-5018展現出顯著的抗腫瘤活性:其中一模型實現完全緩解(CR),另一模型出現明顯腫瘤縮小,為推進臨床研究提供了有力支持。除ACC外,公司還計劃將PIN-5018拓展至轉移性去勢抵抗性前列腺癌(mCRPC)、結直腸癌及其他罕見腫瘤領域。
PAS-004:公布1/1b期臨床試驗數據

Pasithea Therapeutics公司公布了其大環MEK抑制劑PAS-004用于治療成人神經纖維瘤病1型相關叢狀神經纖維瘤(NF1-PN)的積極1/1b期臨床試驗數據。與目前FDA批準的MEK抑制劑不同,PAS-004是大環化合物,環化可增強藥物與靶受體的結合,被認為有望改善藥代動力學和安全性。
此次公布的結果顯示,PAS-004片劑的PK暴露量隨劑量增加呈比例上升,半衰期約57小時。片劑更優的PK特性使得更低劑量即可達到與膠囊相同的暴露水平,同時具備更高的可預測性和更低的個體間差異。在穩態下,片劑的Cmax/Cmin比值<2。
VT-5006:啟動1期臨床試驗

Vertero Therapeutics公司宣布啟動其潛在“first-in-class”、用于治療帕金森病的腸道選擇性小分子藥物VT-5006的1期研究。該藥物通過作用于胃腸道壁中存在的微生物淀粉樣蛋白CsgA開發,CsgA能驅動α-突觸核蛋白(?Syn)的聚集和炎癥反應,炎癥傳播至大腦將引發帕金森病進展。VT-5006旨在通過靶向CsgA減少?Syn聚集負荷并抑制炎癥,從而可能緩解癥狀并減緩疾病進程,幫助患者維持功能狀態。此次開展的試驗基于前期令人鼓舞的臨床前研究結果,這些研究表明VT-5006可以減少腦部病理變化和炎癥,改善運動功能并延緩疾病進展,同時表現出良好的安全性特征。
