Yaqrit推進氨清除劑進入第三期臨床試驗




Yaqrit為氨清除劑的肝性腦病進入第三階段準備

2025年2月11日 05:00 ET | 來源:Yaqrit

Yaqrit於2024年9月收購了來自Mallinckrodt Pharmaceuticals的急性和慢性肝性腦病治療方案,並為其氨清除劑L-ornithine phenylacetate(OPA)進入第三階段做準備。這項發展將通過Yaqrit新成立的子公司Amalive Limited進行,該公司名稱反映了氨水平對晚期肝病患者生活的深遠影響。

Amalive正在為第三階段準備靜脈注射(IV)配方,並根據臨床經驗調整試驗設計,利用人工智能模型指導患者選擇。同時,Amalive將推進口服配方進入第二階段b試驗,以防止肝性腦病的復發。此外,Amalive還正在開發口服液體配方,用於治療和預防與尿素循環酶缺陷相關的高氨血症,這是一種影響兒童的罕見遺傳疾病。

Yaqrit首席執行官Troels Jordansen表示:“OPA是Yaqrit的一項關鍵資產,無論在臨床還是商業上都有潛力,專門致力於其開發的子公司將確保其潛力得到充分發揮。這也為Yaqrit提供了進一步的治療和商業合作的機會。在合適的合作夥伴下,我們準備將這一重要治療推進到第三階段,並基於已證明的急劇降低血氨水平的結果進行推進。”

Yaqrit在2024年下半年收購了OPA的全球開發和商業權利,Mallinckrodt Pharmaceuticals將在達成某些晚期里程碑後獲得付款,並從銷售中獲得版稅。

Yaqrit創始人及首席醫療官Rajiv Jalan教授表示:“OPA鞏固了Yaqrit在開發新型肝病療法方面的領先地位。OPA針對氨毒性,這在脆弱的晚期肝病患者中是一個常見且高死亡率的事件。OPA不僅能直接影響數百萬晚期肝病患者的前景,還為這一嚴重被忽視的人群提供了更多干預的機會。”

OPA由Yaqrit創始人Rajiv Jalan教授在倫敦大學學院的肝衰竭小組發現。OPA的早期開發,包括IV和口服形式的第二階段a和b研究,是在Mallinckrodt Pharmaceuticals的子公司Ocera Therapeutics進行的。現有的臨床數據顯示,OPA能比標準護理更快地降低有毒氨的水平,促進肝性腦病的解決,這是晚期肝病中最常見的併發症之一。通過去除血液中的神經毒性氨,OPA有潛力迅速降低死亡率和多脏器衰竭的風險。

評論

Yaqrit的進展無疑是肝病治療領域的一個重要里程碑。隨著氨清除劑OPA進入第三階段臨床試驗,這不僅展示了公司在創新療法開發方面的潛力,也反映了對於肝性腦病這一嚴重健康問題的重視。肝性腦病的高復發率和與之相關的死亡風險,突顯了新療法的迫切需求。

值得注意的是,Yaqrit的策略不僅限於藥物開發,還包括利用人工智能技術來優化患者選擇,這可能會提高臨床試驗的效率和成功率。此外,與Mallinckrodt的合作關係也為Yaqrit提供了穩固的財務支持,這對於推進其研發計劃至關重要。

然而,隨著臨床試驗的推進,Yaqrit需要面對的挑戰也不容忽視,包括如何有效地進行市場推廣以及與其他競爭者的競爭。這些因素都將影響OPA的最終商業化進程。因此,Yaqrit在未來的發展中,必須保持靈活性和創新性,以應對不斷變化的市場需求。

Generate an ultra-realistic, highly ultra-detailed, 8k resolution with 1080x1080 pixel portrait of me using the uploaded image for reference (preserved the likeness and the original face for reference) of a striking, high-resolution portrait of a young woman with long, flowing wavy brunette hair, seated gracefully on a simple black wooden chair in a dimly lit studio. She wears an oversized, off-white knitted sweater that drapes loosely over her frame, slipping off one shoulder to reveal smooth skin and add a subtle touch of sensuality. Her pose is elegant and contemplative: one arm rests gently on the chair’s backrest while her hand delicately supports her chin, and her gaze is directed thoughtfully toward the side, creating an intimate and introspective mood. The lighting is expertly crafted with a single soft, directional light source positioned to the side, casting gentle shadows that sculpt her form and highlight the texture of the knitwear and the natural contours of her legs and arms. This chiaroscuro effect enhances the depth and dimensionality of the image, emphasizing the softness of her skin and the intricate weave of the sweater. The background is a smooth, muted dark gray, providing a minimalist and distraction-free backdrop that contrasts beautifully with her light-colored apparel and warm skin tones. *** The composition is a full-body vertical frame that captures the model’s seated posture with perfect balance, positioning her slightly off-center to create visual interest and harmony. The overall color palette is subdued and warm, featuring neutral tones that evoke a sense of calm and understated elegance. The image is impeccably sharp, showcasing fine details such as the delicate waves of her hair, the subtle folds in the fabric, and the natural texture of her skin. The style is classic and timeless, blending modern minimalism with emotive portraiture to convey quiet strength, beauty, and introspection.
