新型瘦瘦針CBL-514誘導脂肪細胞凋亡,第2期人體試驗顯示內臟脂肪下降12.01%

Quick Look

台灣生技公司參與研發的新型瘦瘦針CBL-514,作用機制為直接誘導脂肪細胞凋亡,而非透過降低食慾減重。第2期人體試驗資料顯示,接受治療者的腹部內臟脂肪體積在最後一次治療後4週平均下降12.01%,安慰劑組則增加5.68%。研究由美國阿拉巴馬大學伯明罕分校與康霈生技團隊於歐洲糖尿病研究協會年會發表,目前已進入第3期試驗,首批結果預計於2027年底公布。

Why It Matters

目前常見的GLP-1減重藥物主要透過降低食慾來達成減重效果,而CBL-514採取不同機制,直接誘導脂肪細胞凋亡。此項技術由台灣康霈生技與美國研究團隊合作開發,旨在提供非手術腹部減脂的替代方案。

〔編譯陳成良/綜合報導〕台灣有生技公司參與研發的新型瘦瘦針CBL-514,作用方式與目前常見的GLP-1減重藥物不同,並非主要透過降低食慾來減重,而是直接誘導脂肪細胞凋亡。最新第2期人體試驗資料顯示,接受CBL-514者的腹部內臟脂肪體積,在最後一次治療後4週平均下降12.01%。

醫療新聞網站《Medical Xpress》報導,這項研究於9月28日至10月2日在義大利米蘭舉行的歐洲糖尿病研究協會(EASD)年會發表。研究由美國阿拉巴馬大學伯明罕分校(University of Alabama at Birmingham)研究人員賈維(W. Timothy Garvey),以及康霈生技執行長暨研發長凌玉芳等人進行。

請繼續往下閱讀...

CBL-514的主要作用,是選擇性誘導脂肪細胞產生細胞凋亡(apoptosis),也就是讓脂肪細胞自行死亡。研究團隊這次針對第2期試驗中具有核磁共振造影(MRI)資料的40名受試者進行分析,其中23人接受CBL-514、17人接受安慰劑,每3週在下腹部接受注射,療程最長12週。

MRI結果顯示,最後一次治療後4週,CBL-514組的內臟脂肪體積平均較基準值下降12.01%,安慰劑組則增加5.68%,兩組相差17.69個百分點。到了最後一次治療後8至12週,CBL-514組的內臟脂肪體積仍較基準值低10.45%,安慰劑組則增加11.76%。

這次人體分析僅涵蓋40名受試者

先前第2期試驗資料也顯示,CBL-514可降低皮下脂肪體積,69.6%接受治療者在8週追蹤時至少減少150毫升,安慰劑組則為0%。研究期間主要出現注射部位疼痛、腫脹及發紅等輕度至中度且短暫反應,未報告嚴重不良事件。

研究團隊也在動物實驗中觀察到,CBL-514與GLP-1藥物tirzepatide合併使用時,大鼠減重幅度較大;停止tirzepatide後,合併CBL-514的大鼠體重回升幅度也較小。不過,這部分目前只有動物研究資料,研究者提出的「減少脂肪細胞可能降低復胖」也仍屬假設,不能直接套用到人體。

CBL-514目前已進入第3期隨機安慰劑對照試驗,將進一步評估非手術腹部減脂的安全性與療效,首批結果預計於2027年底公布。

Ma Ruishan, director of the Department of Pediatrics at Changhua Hospital of the Ministry of Health and Welfare, pointed out that this year’s influenza epidemic has continued since midsummer, and type A H1N1 is the main virus strain. Severe cases are more common in the elderly over 65 years old and patients with chronic diseases. In view of the influenza epidemic period in Japan, South Korea, Hong Kong and other places, as well as the rising epidemic trend in China and Singapore, he suggested that elders and patients with chronic diseases who plan to go abroad should get vaccinated two weeks in advance to ensure that protection is established before going abroad and reduce the risk of infection and severe illness.
