Pleco藥業PTX-252獲FDA正面回應,推進急性白血病治療




Pleco Therapeutics 宣布與 FDA 的 Pre-IND 會議結果正面,針對急性髓性白血病的 PTX-252

2025年3月26日,荷蘭奈梅亨——Pleco Therapeutics,一家專注於開發難治性癌症新療法的臨床階段生物製藥公司,宣布其與美國食品藥品監督管理局(FDA)舉行的預備性新藥(Pre-IND)會議取得正面結果。此次會議主要針對 PTX-252 的持續開發,這是一種旨在治療急性髓性白血病(AML)患者的靜脈注射(IV)配方。

在這次 Pre-IND 會議中,公司有機會討論其新藥申請(IND)開發計劃,並獲得 FDA 對其新藥候選者 PTX-252 的非臨床和臨床研究要求的指導。來自血液惡性腫瘤部門的書面回應中,FDA 提供了建設性的反饋,並對 Pleco 提出的開發策略表示支持。

PTX-252 是一種小分子,旨在去除腫瘤微環境中的有毒重金屬,改善腫瘤抑制蛋白 p53 的功能,從而提高癌細胞對化療的敏感性。該化合物已獲得 FDA 的孤兒藥物認證,用於 AML 的治療。

Pleco Therapeutics 的創辦人兼聯合首席執行官 Ivo Timmermans 表示:「FDA 的建設性反饋支持我們將 PTX-252 帶給治療選擇有限的癌症患者的使命。這些指導為我們開啟 IND 提供了清晰的前進路徑,使我們能夠儘快將 PTX-252 推向臨床。」

Pleco Therapeutics USA 的總裁 Michael Stalhamer 說:「在藥物開發的早期與美國 FDA 和其他監管機構合作是關鍵的一步。Pleco Therapeutics 感謝這些反饋,這有助於明確和簡化我們的臨床開發計劃,同時確保一條安全有效的監管途徑以惠及患者。」

Pleco 正與位於比利時的專業製藥公司 Hyloris Pharmaceuticals 共同開發 PTX-252。

這次 Pleco Therapeutics 與 FDA 的會議結果顯示出公司在急性髓性白血病治療領域的潛力,尤其是 PTX-252 的開發。PTX-252 的設計理念不僅是針對癌細胞本身,還試圖改善腫瘤微環境,這是一個相對創新的思路。這種方法可能會為傳統治療方法帶來突破,特別是在目前治療選擇有限的患者中。

此外,Pleco 的合作夥伴 Hyloris Pharmaceuticals 也表明了跨國合作在生物製藥領域的重要性,這不僅能加速研究進程,還能整合不同地區的專業知識與資源。隨著全球對癌症治療的需求不斷上升,Pleco 的發展策略和 FDA 的支持無疑為未來的臨床試驗鋪平了道路,值得業界密切關注。

A dynamic, ultra-realistic action shot of a snowboarder performing a high-air jump on a snowy mountain slope. The rider wears a bright green winter jacket, black snow pants, gloves, and a dark beanie, with reflective goggles catching the cold mountain light. A cloud of visible breath escapes from the rider’s mouth in the freezing air. Snow explodes upward from the snowboard, creating sharp, frozen particles suspended mid-air. The background features a dramatic high-altitude landscape with forested slopes and distant mountains under soft, cold blue lighting. Capture cinematic contrast, DSLR realism, 85mm lens, f/2.8, crisp details, slow-motion energy, dynamic composition, atmospheric depth, high-clarity sports photography. Prompt (Enhanced, Artistic & Detailed):

A young Asian female inspired by "Imada Mio's" delicate doll-like aesthetic (精緻洋娃娃臉), featuring extraordinarily large, round, and soulful eyes with subtle brown irises, framed by long fluttering lashes. Her face is petite and exquisitely shaped with a defined V-line jaw, soft rosy cheeks flushed with youthful vitality, and plush, natural lips softly parted in a gentle, innocent yet slightly flirtatious expression. Her complexion is luminous and porcelain-smooth.

Her hair is long, dark chocolate brown, and styled in an artfully messy “just woke up” look (剛睡醒的凌亂感), with tousled waves and a touch of natural volume that frames her face and cascades down her shoulders, effortlessly blending wildness and charm.

She wears an oversized, semi-sheer white button-down shirt in a borrowed-from-the-boyfriend style (男友風白襯衫); the shirt slips loosely off her slim shoulders, unbuttoned at the top to reveal graceful collarbones and a hint of décolleté. The hem of the shirt falls mid-thigh, creating a tasteful "bottomless" look (下衣失蹤風格), her bare legs just visible beneath the diaphanous fabric, enhancing a pure yet subtly sexy visual impact.

The image is rendered with a high-key, natural daylight aesthetic reminiscent of Japanese gravure photobooks (寫真集風格): bright, airy lighting softly illuminates her features, casting gentle highlights and diffuse shadows for a dreamy, ethereal effect. Skin is rendered creamy and velvety with impeccable smoothness. The color palette echoes Fujifilm PRO 400H—soft, milky tones with delicate pastels, gentle greens, natural skin, and a nostalgic film grain that adds warmth and authenticity, evoking an elegant, fresh, and intimate atmosphere.

She is posed naturally, perhaps seated on light bed linens or by a sunlit window, exuding a blend of youthful innocence, pure allure, and quiet confidence. Hyper-detailed, cinematic composition, fine-tuned for photorealism yet with a subtle artistic charm. {

    "prompt": "Ultra-realistic portrait of a man walking toward the camera on an airport runway at night He wears a white long-sleeve shirt with sleeves rolled up and dress pants, shoes. The camera is very close, capturing his face sharply - textures of skin, smoke from his lips, and subtle reflections of firelight in his eyes. Behind him, slightly out of focus, a commercial airplane is burning intensely, with huge flames, roaring firestorms, and thick black smoke rising high. The fiery glow casts dramatic orange highlights on his shirt and face, creating deep shadows and a gritty, cinematic mood. Wet runway reflects the blaze, enhancing the dramatic atmosphere.",
