美FDA拒認新藥聯用治療創傷後壓力症有效




美國FDA顧問委員會反對Otsuka製藥與Viatris合作的PTSD治療藥物療效

美國食品藥品監督管理局(FDA)一個由獨立專家組成的顧問委員會於星期五投票,反對Otsuka製藥研發的藥物與Viatris公司生產的抗抑鬱藥Zoloft(舍曲林)聯合使用,治療成人創傷後壓力症候群(PTSD)的療效。

該委員會以10票贊成、1票反對的結果認為,現有的數據並不足以證明這種聯合療法對於PTSD的治療有效。

PTSD是一種由極度壓力事件引發的心理障礙,影響約4%的美國成年人,常見於戰爭退伍軍人,但自然災害、虐待或其他創傷事件同樣可在普通民眾中誘發此症。

此次建議是在FDA工作人員於星期三提出質疑後作出的,他們指出該聯合療法的臨床試驗結果不一致,且治療效果僅屬輕微。

編輯觀點與深入分析

這次FDA專家委員會對Otsuka與Viatris合作的PTSD療法給予否定意見,凸顯了現代精神醫學領域中藥物開發的複雜挑戰。PTSD作為一種多因子、多層面的心理疾病,其治療效果受限於個體差異、病症複雜性及評估標準的多樣性。即使是已有的抗抑鬱藥物如Zoloft,也未必能有效覆蓋所有患者的症狀。

這次的結果反映出單純依賴藥物聯合治療來解決PTSD仍存在很大不確定性,或許更需要結合心理治療、行為治療及社會支持的多管齊下策略。從藥物研發角度看,這也提醒製藥公司在推廣新療法前必須確保臨床數據的堅實和一致性,避免過早期望落空。

此外,FDA的嚴謹審查體系再次彰顯了其在保障患者安全和治療有效性上的角色,這對醫療市場的健康發展至關重要。對香港及全球的精神健康市場而言,這一案例提醒我們,面對精神疾病的複雜性,醫療創新不僅要追求新藥研發,更需重視整體療效和患者福祉的平衡。

Highly detailed, artistic illustration of two cats sitting together on the bustling Nathan Road in Hong Kong. One cat is a sleek black feline with emerald green eyes, the other is a fluffy ginger tabby with white paws. They are perched near the neon-lit storefronts and glowing billboards, surrounded by vibrant city life: crowds of people, bright taxis, and street vendors selling local food. The scene is alive with colorful reflections on rain-slicked pavement, atmospheric mist, and dramatic lighting from neon signs in Chinese characters. The artistry should blend urban realism with a touch of whimsical charm, focusing on the cats' expressive faces and the dynamic ambiance of Nathan Road at night. A striking black-and-white cinematic photograph of a mysterious woman standing calm and composed in the center of a dense crowd of paparazzi, dozens of photographers surrounding her, all aiming vintage cameras with flashes raised. The woman wears dark sunglasses, minimal makeup, and an elegant dark outfit, her expression emotionless and powerful, symbolizing isolation amid fame. High contrast lighting, dramatic shadows, shallow depth of field, sharp focus on the central subject, blurred foreground faces and cameras, classic film grain, 35mm analog photography style, noir aesthetic, timeless Hollywood atmosphere, intense realism, editorial fashion photography, moody, iconic, award-winning composition. Prompt:
Use my image in Ultra-realistic, hyper-detailed, 8K cinematic portrait of a young stylish man, using the uploaded image for exact face and hairstyle.
Outfit: An oversized red knit sweater with white hearts, exactly as described in the prompt.
Pose: A hyper-realistic close-up portrait with a messy, cropped framing showing only the boy holding the book. His left hand rests on the wooden table and covers part of his cheek, with a subtle smile on his lips. His other hand holds the book titled "Something I Never Told You" with the word "YOU" written in pink, exactly as
described in the prompt. Background: Not specified.
