聖地亞哥和多倫多,2025年1月9日(GLOBE NEWSWIRE)—— Aptose Biosciences Inc.(“Aptose”或“公司”)(NASDAQ:APTO,TSX:APS)是一家臨床階段的精準腫瘤學公司,今天宣布在TUSCANY 1/2期研究中,首批急性髓性白血病(AML)患者已接受了與venetoclax(VEN)和azacitidine(AZA)聯合的Tuspetinib(TUS)三重療法。

基於Tuspetinib的TUS+VEN+AZA三重療法正在TUSCANY 1/2期試驗中推進,目標是為新診斷的AML患者創造一種改善的前線療法,該療法對多樣化的AML人群有效,持久且耐受性良好。早期的APTIVATE試驗顯示,TUS作為單一藥物及與VEN聯合使用時,對多種復發或難治性(R/R)AML人群展現了良好的安全性和廣泛的活性,這些人群超出了預後較好的NPM1和IDH突變亞組。TUS在接受過VEN和FLT3抑制劑(FLT3i)治療的患者中也觀察到了反應,並且在具有高度不良TP53和RAS突變的患者以及具有突變或未突變(野生型)FLT3基因的患者中亦有良好效果。Tuspetinib是一種方便的每日一次口服藥物,而TUS+VEN+AZA三重療法有潛力以無突變的方式治療更大範圍的AML人群,而不僅僅是狹窄的亞群體。

“Aptose的首批幾位TUSCANY試驗患者已經接受了TUS+VEN+AZA治療,我們感到非常興奮,”Aptose首席醫療官Rafael Bejar醫生表示。“TUS+VEN+AZA三重療法有望為新診斷的AML患者提供高反應率和更長的生存期,同時避免其他藥物所見的毒性,從而擴大三重療法的應用範圍,惠及更多包括具有不良疾病特徵的AML患者。”

TUSCANY:TUS+VEN+AZA三重療法1/2期研究

TUSCANY三重療法1/2期研究旨在測試TUS與標準劑量的azacitidine和venetoclax聯合使用的各種劑量和時間表,針對不符合接受誘導化療的AML患者。TUS將在28天的周期內給予,起始劑量為每日40mg,並計劃在每個劑量水平的安全性評估後進行劑量增加。多個美國地點正在招募參與TUSCANY試驗,預計到2025年中至晚期將招募18-24名患者。

編輯評論:這項研究的開展對於急性髓性白血病的治療具有重要意義,特別是對於那些突變多樣的患者群體而言。傳統上,AML的治療多依賴於特定的基因突變來選擇合適的療法,而Tuspetinib的三重療法有可能改變這一現狀,提供一種更為廣泛的治療選擇。這不僅能提高治療的有效性,還能降低患者在治療過程中遭遇的毒性反應,這對於改善患者的生活質量至關重要。隨著臨床試驗的推進,期待能夠看到更多有關這種療法的數據,並希望它能在未來成為AML治療的標準選擇之一。

Certainly! Here’s an enhanced, detailed, and artistic version of your prompt:

A charming and elegant cat sitting gracefully on a Parisian balcony, overlooking the romantic cityscape of Paris at sunset. The cat’s fur is soft and glossy, perhaps a classic tabby or a sleek black cat, with expressive, intelligent eyes. Delicate wrought-iron railings surround the balcony, adorned with blooming flower boxes of vibrant geraniums and lavender. In the distance, the Eiffel Tower rises majestically above the rooftops, bathed in warm golden and pink light. The artist’s style is a blend of impressionism and realism, capturing intricate city details—cobblestone streets, classic Parisian architecture, and atmospheric lighting. The mood is dreamy, whimsical, and full of European charm, evoking a sense of wonder and adventure. Ultra-realistic high-fashion studio portrait of a woman [image uploaded], vertical composition, framed from mid-chest to top of head. Camera at eye level, straight-on angle with a very slight head tilt to the subject’s left. Posture & pose: upright posture, shoulders relaxed. Left shoulder slightly forward, creating a gentle diagonal line across the collarbones. Arms relaxed out of frame, fur wrap resting naturally over the shoulders. Expression: calm, elegant, and composed. Soft neutral gaze directly into the camera, slightly parted lips with a subtle natural gloss. No smile, refined and confident mood. Face & skin: smooth fair skin with realistic texture and pores, soft luminous finish (not plastic or airbrushed). Rosy blush concentrated on the apples of the cheeks. Natural highlight on nose bridge, cheekbones, and collarbones. Eyes & makeup: large almond-shaped eyes, cool gray-brown irises. Long curled lashes, soft eyeliner, muted rose eyeshadow blended outward. Straight natural brows with gentle arch. Hair: short black bob cut just above the shoulders, slightly wavy ends. Center part with soft wispy strands framing the face. Large black satin bow tied at the back of the head, visible above the crown. Accessories: silver floral drop earrings with dangling details. Matching silver statement necklace with a central floral pendant resting at the upper chest. Clothing & styling: beige satin slip dress with thin spaghetti straps, smooth fabric with subtle sheen. Black faux-fur stole draped loosely around both shoulders, adding contrast and texture. Background: clean seamless light gray to off-white studio backdrop, evenly lit with no visible texture or distractions. Lighting: soft diffused beauty lighting from the front and slightly above eye level. Gentle fill light to reduce shadows, subtle rim light outlining hair and shoulders. Balanced highlights without overexposure. Color palette: neutral beige, black, silver, soft pink skin tones, minimal and elegant. Camera & settings: full-frame DSLR or mirrorless, 85mm lens, f/2–f/2.8, ISO 100, high sharpness on eyes, shallow depth of field. Image quality: ultra-high resolution, professional fashion photography, crisp details, natural skin realism. Strictly photorealistic human portrait — no illustration, no anime, no CGI, no digital painting, no doll-like skin. Base Setup
keep 100 percent facial information adherence of the attached image and turn her into a lone traveler posed on a sunlit desert dune ridge, captured as a live action photograph or movie still, not an illustration or CGI render, with a sexy, confident, heat soaked editorial mood.

Shot and Camera
Full body shot from slightly low height, framing her on the right third, with sweeping dunes rolling into the distance on the left, using a wide cinematic lens feel that keeps the landscape vast and minimal.

Identity and Pose
She has a slim, toned build, medium height impression, sun kissed skin, and long loose hair blown by the wind. She stands barefoot on the crest, one leg forward so the hip shifts naturally, one hand resting on her upper thigh and the other lightly gripping a sheer wrap at her side, wearing a high cut desert bikini with a gauzy open sarong that shows plenty of leg and midriff without nudity, head turned over her shoulder with a subtle, knowing smile, 8k Photorealistic and hyper realistic.

Lighting and Environment
Harsh midday sun from high right casts crisp shadows along her body and the dune ripples, with soft sky bounce filling the shadows enough to keep detail. The sand textures, wind carved ridges, and pale blue sky remain exactly like the reference, with faint footprints and slight imperfections grounding her on the slope.

Masking and Constraints
Change only by adding the subject and her wardrobe, keep dune shapes, lighting direction, perspective, horizon line, and white balance identical, preserving realistic body proportions and clear contact between her feet and the sand. Absolutely no added text, no painterly or toon look, no CGI plastic skin, no see through fabric on intimate areas, no warped limbs or floating feet, strictly require consistent perspective, natural film like grain, fine skin texture and sand detail, and physically correct contact shadows in the sand depressions around her feet.
