iBio新抗體助減肥 食慾減六成股價飆50%




iBio股價飆升50% 新型胰淀素受體激動抗體大幅減少肥鼠食量

美國生物科技公司iBio Inc(NASDAQ代號:IBIO)近日公布其工程化胰淀素(amylin)受體激動抗體在肥胖小鼠模型中的前臨床數據,顯示該抗體可將急性食物攝取量減少60%,消息一出,iBio股價即飆升50%。

這間利用人工智能驅動的生物科技企業表示,與AstralBio的合作已成功研發多款針對胰淀素受體的全新工程化抗體激動劑。胰淀素受體屬於異源二聚體G蛋白偶聯受體。iBio的策略聚焦於選擇性激活胰淀素受體,而非同時激活胰淀素和降鈣素受體(即所謂的雙激動劑DACRA),他們相信這種方法在提升療效的同時,能帶來更好的耐受性。

iBio的技術能精準針對胰淀素受體及其亞型,令公司具備在快速成長的肥胖症治療市場中競爭的潛力。胰淀素激素天然負責調節飽腹感並延緩胃排空,因此其受體成為治療肥胖和心代謝疾病的理想目標。

公司補充,其他胰淀素類似物在臨床開發中,與semaglutide聯用時體重減輕幅度高達22.7%,單獨使用時則有11.8%。而iBio的抗體則鎖定不同訊號通路,未來有望與GLP-1受體激動劑合用提升減重效果,或成為對GLP-1療法反應不佳患者的替代選擇。

iBio運用其專利藥物發現平台及先進AI技術,致力開發具高選擇性和效力的抗體,目標是發現能成為減重領域「最佳藥物」的分子,兼顧療效、耐受性及保持瘦體重。

評論與啟示

iBio此次新藥研發進展不僅體現了人工智能在生物藥物設計上的巨大潛力,更凸顯了肥胖症治療領域對於更精準、耐受性更佳療法的迫切需求。現有市場中以GLP-1受體激動劑為主流治療,雖然效果顯著,但仍有不少患者無法達到理想體重控制,或因副作用而中斷治療。iBio主打的胰淀素受體選擇性激動,提供了一條全新路徑,有望補足現有療法的不足。

此外,iBio放棄雙重激動劑策略,改以單一受體精準激活,這種「精細調控」的藥物設計理念值得關注。它反映出未來生物製藥將更注重分子機制的微調,追求療效與安全性的最佳平衡。

對香港及全球醫藥投資者而言,iBio的技術路線和市場定位都極具吸引力。肥胖症作為全球公共衛生挑戰,相關治療市場擴張迅速,具備創新療法的公司將贏得資本青睞。不過,前臨床數據雖鼓舞人心,仍需審慎觀察其臨床試驗階段的安全性及長期療效。

綜合來看,iBio的最新成果展示了AI驅動的藥物研發如何推動生物科技創新,並為肥胖症患者帶來新的治療希望。未來若能成功轉化為臨床療法,將對健康醫療產業產生深遠影響,也為投資者提供了值得關注的潛力標的。

一位年輕亞洲美女,長直黑髮輕微笑,精緻五官,穿白色露肩毛衣和輕薄長裙,赤腳坐在明亮室內地板上,地上一束玫瑰花束,柔和自然光線從窗戶灑入,溫暖氛圍,高清寫實肖像攝影。 Use the original face exactly as it is, without changing a details. A female model with sharp features, defined cheekbones, and intense, direct eye contact (though eyes are slightly in shadow from the hat).
• Aesthetic: Vintage fashion, Pin-up, 1950s/1960s style, high-glamour, summer resort wear.
• Lighting: Bright, harsh sunlight creating high contrast and crisp shadows. The light should perfectly illuminate the skin and the vibrant colors of the dress.
• Color Palette: Dominated by vibrant yellow, crisp white, and bold red, accented by deep black.
Specific Outfit & Details:
• Dress: A bright yellow halter-neck sundress with a classic white polka-dot pattern. It has a fitted, sweetheart neckline or bustier-style top that enhances the silhouette.
• Accessories:
• A very large, wide-brimmed sun hat in crisp white (or light straw/fabric) that casts a shadow over the upper face.
• A matching yellow polka-dot scarf tied closely around the neck (like an ascot or choker-style).
• Large, striking black statement earrings (circular, drop, or bead style).
• Bold red lipstick is a key feature, contrasting sharply with the yellow and white.
Technical/Camera Details:
• Shot: Close-up or medium-close-up portrait, focusing on the torso, neckline, face, and hat.
• Depth of Field: Shallow (low f-stop), with the model in sharp focus and the background slightly blurred (bokeh).
• Background: Out-of-focus, suggesting a bright outdoor location, with abstract shapes of boats/yachts (white and red accents visible) in a marina setting. [Enhanced Artistic Prompt]

A highly detailed portrait of a young Asian woman inspired by the delicate, doll-like beauty of Imada Mio (精緻洋娃娃臉). She has large, round, luminous eyes with a deep, expressive gaze, a petite V-shaped face, full rosy cheeks, and porcelain-soft skin. Her expression is a captivating blend of innocence, youthful energy, and subtle flirtation, capturing an aura of pure allure.

Her hair is long, dark chocolate brown, with natural volume and texture—slightly tousled in an artful, “just woke up” messy style (剛睡醒的凌亂感), with soft strands falling over her face and shoulders. She wears an oversized, semi-translucent white button-down boyfriend shirt (男友風白襯衫), loosely draped and unbuttoned at the top, elegantly revealing her collarbones and creating a “bottomless” fashion look (下衣失蹤風格) with a sense of relaxed intimacy.

The overall aesthetic is reminiscent of a contemporary Japanese Gravure photobook (寫真集風格), evoking both pure charm and subtle sensuality (Pure & Sexy vibe). Use bright, high-key natural lighting to create a soft, ethereal glow, with smooth, radiant skin texture. Emphasize pastel color grading and gentle film grain, referencing the signature look of Fujifilm PRO 400H for a dreamy, cinematic finish. Compose the image artistically, focusing on beauty, mood, and expressive detail, as if captured in a candid, intimate moment.

— full body or mid-length portrait, shallow depth of field, delicate highlights, softly blurred minimalist background, inviting eyes, tasteful and elegant composition.
