聖地牙哥,2025年7月1日(GLOBE NEWSWIRE)—— Inmagene生物製藥公司(“Inmagene”)是一家專注於開發創新和差異化療法的臨床階段生物技術公司,致力於治療免疫和炎症性疾病。今天宣布在其全球多中心第二階段2b劑量尋找研究(ADAPTIVE試驗,NCT07037901)中成功為首位中度至重度特應性皮膚炎(AD)患者進行了給藥。

“Inmagene創始人、董事長兼首席執行官Jonathan Wang博士表示:‘我們很高興在這項試驗中為首位患者進行給藥,這是基於之前觀察到的令人鼓舞的臨床數據。’ ‘IMG-007針對OX40受體,阻斷OX40–OX40L信號傳導,並且其靜默的抗體依賴性細胞介導的細胞毒性功能消除了T細胞耗竭的影響,從而可能降低安全風險。此外,其延長的半衰期支持便捷的給藥。這些特性使IMG-007成為一個潛在的差異化治療候選藥物,適合AD患者。’”

ADAPTIVE是一項隨機、雙盲、安慰劑對照的第二階段2b試驗,旨在評估IMG-007在對局部AD療法反應不足和/或不耐受的活躍中度至重度AD成人參與者中的幾種皮下注射劑量方案的有效性和安全性。該試驗計劃招募約220名患者,分為四個治療組(高劑量、中劑量、低劑量IMG-007和安慰劑),比例為1:1:1:1。
試驗包括兩個不同的治療期間:

* 期間1:為期20週的隨機雙盲安慰劑對照治療期
* 期間2:隨後的32週雙盲主動治療期,所有參與者,包括最初隨機分配到安慰劑的患者,將接受主動治療

該研究的主要終點是在第20週時,Eczema Area and Severity Index(EASI)分數的平均百分比變化。主要次要終點包括第16週時EASI分數的平均百分比變化,以及在第16週和第20週時,達到EASI-75(EASI分數改善≥75%)和研究者全球評估(IGA)分數為0或1(清晰或幾乎清晰)的患者比例。

第二階段2b ADAPTIVE試驗的初步結果預計將在2026年第四季度公布。這項劑量尋找研究旨在生成數據,以指導未來第三階段臨床試驗的設計和最佳劑量方案的選擇。

關於IMG-007

IMG-007是一種人源化的皮下注射非耗竭性IgG1單克隆抗體,針對OX40。它具有靜默的抗體依賴性細胞介導的細胞毒性功能和延長的半衰期。OX40–OX40L信號在T細胞的激活、擴展和存活中起著關鍵作用,使其成為治療免疫和炎症性疾病的有吸引力的靶點。在非臨床研究中,IMG-007顯示出強效的OX40–OX40L信號抑制。其皮下注射劑型在預期的治療劑量水平下顯示出34.7天的半衰期,支持不頻繁和便捷的給藥。在一項針對中度至重度特應性皮膚炎患者的第二階段2a試驗中,IMG-007顯示出持續的臨床活性,且耐受性良好,未報告發熱或寒戰的案例。IMG-007最初由HUTCHMED發現。

關於Inmagene生物製藥公司

Inmagene是一家全球臨床階段的生物技術公司,專注於開發創新療法以治療免疫和炎症性疾病。該公司的主要產品IMG-007目前正在進行第二階段開發,用於治療中度至重度特應性皮膚炎和斑禿。Inmagene的產品線還包括IMG-004,一種非共價、可逆的口服BTK抑制劑,具有延長的半衰期和持續的藥效,支持每日一次的給藥。IMG-004已準備進入第二階段臨床開發。

在這項研究中,Inmagene的IMG-007顯示出對特應性皮膚炎患者的潛在治療價值,尤其是在目前市場上針對該病症的治療選擇相對有限的情況下。這不僅是對患者的希望,也是對生物製藥行業的一次重要推進。隨著對OX40的深入研究,未來可能會有更多針對免疫疾病的創新療法問世,這將改變患者的治療方式和生活質量。

Create a hyper-realistic 8K close-up body portrait of a female model, using the uploaded photo as the exact facial reference. Maintain 100% accuracy of the facial features — do not alter or modify any aspect of the face. Render the skin texture, lighting, and overall composition with photo-realistic detail, ensuring lifelike color tones and natural depth of field. A man with his original hair is sitting casually on a white cube, smiling warmly at the camera. He is wearing a cream-colored cable-knit sweater, blue jeans, and brown loafers. His legs are crossed, with one hand resting on his knee.
The background reveals a cozy and festive living room. A large, beautifully decorated Christmas tree with numerous warm lights and gold ornaments stands prominently behind him. Several wrapped gift boxes are visible at the base of the tree. To his left, another smaller decorated Christmas tree and a wreath on the wall further enhance the holiday atmosphere. The lighting is soft and inviting, creating a warm and welcoming scene. An intense, close-up portrait set in a smoky, underground jazz club or speakeasy. The subject is the 'Boss' of an information network, hiding in plain sight. The scene is dark, defined by heavy shadows and cigarette smoke swirling in the air. A single spotlight hits the subject from the side, creating a classic 'Rembrandt triangle' on the cheek of [exactly face uploaded image 100%]. He wears a sharp, pinstripe suit with a silk tie, loosened at the collar. He holds a glass of amber whiskey, the condensation rendered in 8K detail. The camera uses a macro 100mm lens, focusing entirely on the eyes and the texture of the skin, blurring out the background patrons into abstract shapes. The mood is conspiratorial, sophisticated, and deeply atmospheric. 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 cinematic studio portrait of a woman seated on a simple wooden chair with a minimalist design, positioned slightly to the left of the frame. She is captured in a contemplative pose, with her body turned to the left, her left arm resting gracefully on the back of the chair, and her right hand gently touching her face near her lips, conveying a sense of introspection and elegance. Her long, wavy hair cascades naturally over her shoulders, framing her face and adding softness to the composition. She wears an oversized, textured knit sweater that slips off her shoulders, exposing her collarbones and upper chest, emphasizing a relaxed and intimate mood. Her legs are bare, with her right foot flat on the ground and her left knee slightly raised, creating a dynamic line that guides the viewer’s eye through the composition. *** The background is a seamless, deep charcoal or dark brown studio backdrop, providing a rich, neutral setting that enhances the dramatic lighting. The lighting setup features a single, soft yet directional light source positioned to the left of the subject, casting gentle, sculptural shadows that highlight the contours of her face, shoulders, and arms, while creating a subtle gradient across her form. The light accentuates the texture of her sweater and the natural shine of her hair, adding depth and dimension to the image. The color palette is monochromatic with warm, muted tones—shades of gray, brown, and beige—contributing to a timeless, artistic aesthetic. The image is shot with a professional full-frame camera using an 85mm or 50mm lens at a wide aperture (f/1.8 to f/2.😎 to achieve a shallow depth of field, ensuring the subject is in sharp focus while the background remains softly blurred. The resolution is ultra-high, capturing every detail from the fine texture of her sweater to the subtle expression of her pose. The overall style is elegant, contemplative, and refined, emphasizing mood and atmosphere over overt glamour. Post-processing is minimal, maintaining natural skin tones, enhancing contrast and clarity, and preserving the authenticity of the scene. This portrait embodies a delicate balance between simplicity and emotional depth, making it suitable for fine art, editorial, or fashion photography.
