Atsena發表ATSN-201治療視網膜疾病數據




Atsena Therapeutics將於第48屆視網膜學會年會上展示ATSN-201的安全性和有效性數據

2025年2月6日,北卡羅來納州杜漢姆消息(GLOBE NEWSWIRE)—— Atsena Therapeutics是一家專注於基因療法的臨床階段公司,致力於利用基因醫學的力量來逆轉或預防失明。今天,該公司宣布將於2025年2月12日至15日在佛羅里達州夏洛特港舉行的第48屆視網膜學會年會上,展示針對X連鎖視網膜裂孔(XLRS)治療的ATSN-201的安全性和有效性數據。ATSN-201是一種最佳的基因療法產品候選者,利用公司創新的AAV.SPR擴散衣殼,實現中央視網膜光感受器中的治療性基因表達,同時避免了黃斑剝離的手術風險。

展示詳情如下:

– 會議:遺傳性視網膜病變 I:臨床試驗
– 日期和時間:2025年2月13日(星期四)上午7:00-7:45(美東時間)
– 演講題目:ATSN-201劑量遞增研究中X連鎖視網膜裂孔(XLRS)患者的中期安全性和有效性
– 演講時間:上午7:25(美東時間)
– 演講者:Christine Nichols Kay醫生,Atsena Therapeutics臨床眼科顧問

LIGHTHOUSE研究是一項I/II期、開放標籤、劑量遞增和劑量擴展的臨床試驗,旨在評估ATSN-201在年齡六歲及以上的男性XLRS患者中的安全性和耐受性。該研究的招募仍在進行中。欲了解更多信息,請訪問ClinicalTrials.gov(識別碼:NCT05878860)。ATSN-201已獲得美國食品藥品監督管理局的孤兒藥物和罕見兒童疾病認證。

關於X連鎖視網膜裂孔(XLRS)

XLRS是一種由RS1基因突變引起的單基因X連鎖疾病,該基因編碼視網膜裂孔蛋白,主要由光感受器分泌。RS1位於杆狀細胞、圓錐細胞和雙極細胞的細胞外表面。XLRS的特徵是視網膜層的異常分裂,導致視力下降,無法通過眼鏡矯正,最終可能導致失明。XLRS主要影響男性,通常在幼兒期診斷。在美國和歐盟,約有30,000名男性患有XLRS,目前尚無經批准的治療方法。

關於AAV.SPR

AAV.SPR是Atsena的一種新型衣殼,能夠在視網膜注射部位之外進行橫向擴散,從而在注射到黃斑以外的區域時,安全有效地轉導中央視網膜(XLRS患者視網膜中以裂孔腔為主的區域)。在非人類靈長類動物的前臨床研究中,AAV.SPR顯示出能夠促進轉基因表達,超出視網膜注射膨隆的邊緣。這與基準AAV載體形成鮮明對比,後者僅限於原始膨隆的邊緣。在臨床相關劑量下,AAV.SPR能夠有效轉導中央視網膜的圓錐細胞,無需手術剝離,且不會引起炎症。欲了解有關前臨床研究及AAV.SPR工作原理的更多信息,請訪問Atsena的官方網站。

關於Atsena Therapeutics

Atsena Therapeutics(簡稱Atsena)是一家臨床階段的基因療法公司,致力於開發最佳的治療方案,以逆轉或預防由遺傳性視網膜疾病引起的失明。該公司的主要項目正在進行一項針對X連鎖視網膜裂孔(XLRS)的I/II期臨床試驗,這是一種通常在童年時期診斷的遺傳疾病,最終導致失明。Atsena的第一類實驗性基因療法ATSN-101針對Leber先天性黑盲(LCA1),這是兒童失明的最常見原因之一,已完成I/II期試驗並取得積極結果。Atsena正推進ATSN-101,計劃啟動全球關鍵試驗,並與日本新藥公司(Nippon Shinyaku Co., Ltd.)展開獨家戰略合作。Atsena的產品線基於新型的腺相關病毒(AAV)技術,旨在克服遺傳性視網膜疾病所帶來的挑戰。Atsena由眼科基因療法的先驅創立,擁有一支經驗豐富的團隊,致力於滿足視力喪失患者的需求。

在這篇報導中,Atsena Therapeutics的研究不僅展示了他們在基因療法領域的創新,還突顯了對於改善視力健康的潛力。特別是AAV.SPR技術的應用,顯示出在不需要手術的情況下,能夠有效地轉導視網膜,這對於患者來說是一個重大突破。隨著對於X連鎖視網膜裂孔的研究深入,未來有望為數以萬計的患者帶來希望,這也提醒我們在基因療法的發展中,科學的進步如何能夠直接影響患者的生活質量。

Use the original face exactly as it is, without changing a details. A full-body photograph of a glamorous female model in a vibrant, retro 1950s pin-up style bikini. The lighting should be bright, sunny, and highly saturated, evocative of a vintage summer advertisement or a pop art aesthetic.
Model & Outfit:
• Model: A slender woman with a confident, slightly posed expression.
• Hair & Accessories: A white and blue patterned headband tied in a bow. Bold, dark cat-eye sunglasses. Large gold hoop earrings and thick, stacked gold bangle bracelets on both wrists. Bright red lipstick.
• Swimwear: A two-piece retro bikini with a high-waisted bottom and a halter-neck top. The top is turquoise/teal with white polka dots, featuring a large bow detail at the bust. The bottom is a contrasting, high-rise, ruched style in pale peach or coral with small dark polka dots.
Setting & Composition:
• Location: A mid-century modern-style poolside scene on a bright sunny day.
• Background Details: A sparkling blue swimming pool, several brightly colored lounge chairs (yellow, teal, pink), and large beach umbrellas (striped orange and white). There are large, bright flotation devices (yellow, teal, orange inner tube) scattered around the edge of the pool.
• Composition: Vertical, full-body shot. The model is centered, and the background is slightly blurred (shallow depth of field) to keep the focus on the model.
Aesthetic Keywords:
• Vibrant, High Saturation, Retro Summer, 1950s Pin-up, Mid-Century Modern, Pop Art, Poolside Glamour, Commercial Photography, Magazine Ad, Halter Bikini, High-Waisted, Sunny Day. 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 ultra-sharp studio portrait of a confident woman kneeling on the floor with her body slightly leaning back, her right hand gently touching her hair, and her left arm resting on her bent knee. She is dressed in a sleek, strapless black bodysuit that accentuates her figure, paired with elegant black patterned lace pantyhose that add texture and sophistication. She wears a pair of classic black high heels, elevating her posture and emphasizing her elongated legs. The background is a seamless, pure white studio backdrop, providing a clean and minimalist aesthetic that directs full focus to her form and attire. *** The lighting setup is soft, evenly distributed, with a diffused key light positioned to the left, casting gentle shadows that sculpt her contours and highlight the intricate lace pattern of her tights. The overall color palette is monochromatic, emphasizing blacks and whites to create a timeless, sophisticated mood. The composition is carefully balanced, capturing her from the waist up in a slightly angled pose that accentuates her curves and confidence. Use a professional camera with a 85mm or 50mm lens at wide aperture (f/1.8 to f/2.😎 for a shallow depth of field, ensuring crisp detail on her outfit and pose while softly blurring the background. Post-process minimally to enhance clarity, contrast, and natural skin tones, maintaining a polished, elegant, and modern aesthetic suitable for fashion or editorial photography. Create a photorealistic and highly detailed image featuring the attached image walking confidently down a modern city street, accompanied by Jason Statham, Dwayne “The Rock” Johnson, and Jason Momoa acting as bodyguards.

John Wick (Keanu Reeves) is walking just beside or slightly behind the subject, holding an umbrella over him to shield from light rain.

The subject should be the central figure, wearing stylish casual clothing — like a fitted jacket, dark jeans, and sunglasses — exuding calm authority and cool charisma.

Statham, The Rock, and Momoa are dressed in black tactical-style suits, maintaining alert, protective stances, scanning the surroundings like professional bodyguards. John Wick wears his signature black suit and tie, looking composed as he holds the umbrella.

The setting is a downtown urban street with wet pavement reflecting city lights, parked luxury cars, and paparazzi in the background snapping photos.

The photo should look like a real paparazzi shot — slightly off-angle, mid-step motion blur, with realistic lighting and reflections.

Lighting: natural daylight with overcast skies, reflections from wet concrete, realistic shadows, subtle raindrops on the umbrella and clothing.

Camera realism: crisp detail on facial features and clothing textures, shallow depth of field emphasizing the group, with lens flare or light bloom for authenticity.

Mood & tone: grounded, cinematic, and stylish — feels like a moment from a celebrity entourage photo or action-movie press capture, taken with an iPhone by paparazzi.

Style: ultra-realistic, documentary-style street photography with modern cinematic sharpness.
