告別巨痛針！免疫功坊TE-8214：從「麥芽糖」到「水溶液」的長效藥物革命
長效型胜肽藥物的發展，是現代醫學的一大福音，它顯著改善了病患的生活品質。然而，對於「生長激素分泌異常的相關徵兆」的病患來說，儘管現有治療藥物奧曲肽（Octreotide）已能緩解病徵，但長效型製劑的注射疼痛卻是難以言喻的夢魘。在【生活講堂】節目中，主持人—高葳（Stacey） 專訪了台灣免疫功坊（Immunwork）董事長、被譽為「台灣抗體之父」的張子文博士。張博士在訪談中深入揭示，他們正在研發的創新藥物TE-8214，目標就是要徹底解決這個困擾病患數十年的痛點。舊藥之痛：麥芽糖般的黏稠與結節為了將奧曲肽從原本只有1.5小時的短暫半衰期，延長到能數週注射一次的長效療程，現行市場上的長效緩釋劑（如 Sandostatin LAR）必須採用 Depot（儲藏物）的概念。張博士在節目中生動地形容，這種緩釋劑的劑型，在調製出來後，會變成一種「很黏稠的東西，看起來有點像麥芽糖」。這種極端的黏稠度帶來了災難性的後果：1. 粗針深層注射： 由於藥物黏稠難推，病患必須使用極粗的針頭（例如 18G 或 19G），並深層推入臀部肌肉中。張博士提及，有醫師反應，光是看到這種粗針，有的病患就可能害怕得想跑掉。2. 痛苦結節： 藥物在肌肉內釋放時，會在注射部位形成難以消散的硬塊或結節。這類硬塊可能需要數個月甚至一年才能緩慢消退，嚴重影響病患的日常活動和生活品質。新藥突破：脂肪酸束與白蛋白攜帶的長效機制免疫功坊的TE-8214代表了新一代長效藥物在技術與人文關懷上的雙重突破。張博士指出，TE-8214 運用公司獨有的「脂肪酸束的技術」對奧曲肽進行了全新的修飾，創造出獨步全球的創新藥物。最大的突破，在於劑型的徹底改變：TE-8214不再依賴聚合物形成的網狀結構來緩釋藥物，它本身就是水溶液型態。由於是水溶液，TE-8214可以使用極細的針頭（例如 30G，如同疫苗針般細）進行皮下注射，不再需要痛苦的肌肉深層注射，徹底減輕病患的疼痛。長效機制也更為精妙：TE-8214在被皮下注射後會迅速進入血液系統，並與血液中的白蛋白（Albumin）結合。白蛋白作為體內的攜帶者，將藥物攜帶在血液中，使半衰期延長。這種機制既達到了長效的目的，同時也完全避免了肌肉結節的產生。在專訪的最後，張子文博士強調，他的新藥研發不僅追求有效性，更追求人性化。TE-8214目前正在人體臨床試驗階段，一旦成功上市，將為病患提供一個「無痛、細針、不結節」的治療新選擇，讓病患能夠更積極、更有尊嚴地配合治療。
T-E Pharma旗下免疫功坊長效型奧曲肽新藥TE-8214 第一期臨床試驗證實有效改善注射不適、抑制發病生化指標IGF-1
T-E Pharma旗下之免疫功坊 (Immunwork, Inc.) 今日宣布，其自主研發的長效型奧曲肽新藥TE-8214已於澳洲順利完成第一期臨床試驗。結果顯示TE-8214具備良好的安全性與耐受性、可達成預期藥理機制，且皮下注射輕易，不產生施打部位副作用。TE-8214為免疫功坊運用專利平台技術開發之長效型奧曲肽 (octreotide) 類似物，經由在奧曲肽分子上連結含有兩條脂肪酸鏈的脂肪酸束，達成延長藥物半衰期，可應用於治療肢端肥大症與多種神經內分泌腫瘤所引致的病徵。上述兩類疾病常伴隨嚴重的內分泌失調，導致消化性潰瘍、嚴重腹瀉、氣喘、組織異常生長、關節疼痛與高血壓等症狀，若未妥善治療，將大幅影響患者的生活品質與壽命。（圖／免疫功坊提供。）隨著全球對奧曲肽藥物需求的增長，近年來相關市場規模持續擴大，預估2030年將達100億美元。現有市售與研發中的相關產品，多為高黏稠度微粒或凝膠狀緩釋劑型，須使用19G或20G的粗針頭進行肌肉 (如Octreotide LAR) 或深層皮下注射 (如Lanreotide Autogel)，不僅施打困難，更易引發注射部位疼痛及結節等副作用，造成病患對治療的接受度與依從性明顯下降。（圖／免疫功坊提供。）免疫功坊創辦人兼執行長，先前發明多項創新藥物的免疫學家張子文表示：「TE-8214 完成第一期臨床試驗是免疫功坊的重要里程碑，也為肢端肥大症與神經內分泌腫瘤患者帶來新希望。TE-8214具備高水溶性，可透過30G細針頭進行皮下注射，大幅減輕患者注射時的疼痛與恐懼感。未來我們將憑藉此關鍵優勢，積極拓展全球奧曲肽市場，為患者提供更安全、更舒適的治療選擇。」TE-8214的第一期臨床試驗採雙盲、單劑量遞增設計，設有四個劑量組別 (0.6 mg、1.2 mg、2 mg及4 mg)，每組納入8名健康受試者，其中6人接受TE-8214，2人接受安慰劑(生理食鹽水)。整體結果顯示TE-8214耐受性良好，僅出現輕微不良反應，未觀察到任何嚴重不良事件。常見的奧曲肽副作用為消化道不良反應，本試驗24位TE-8214受試者中，僅3人出現極輕微的消化道不適，證實TE-8214的安全性與耐受性表現優異。更重要的是，所有TE-8214受試者均未出現注射部位疼痛或結節情形，結果與安慰劑組的受試者完全相同，顯示TE-8214的劑型設計成功解決緩釋劑型的痛點問題。此外，奧曲肽類藥物主要透過抑制體內類胰島素生長因子 (Insulin-like growth factor 1, IGF-1) 濃度發揮治療效果。在本次試驗的高劑量組別 (2 mg和4 mg) 中，12位TE-8214受試者中有10位 (83%)，其IGF-1濃度下降超過20%，顯示TE-8214具備顯著的IGF-1抑制效果，進一步支持其作為治療用藥之優秀潛力。目前，免疫功坊正積極展開第二期臨床試驗的籌備工作，預計於2025年第三季在台灣正式啟動。我們期盼透過未來階段的試驗推進，加速驗證TE-8214的治療潛力，拓展其臨床應用與全球市場佈局，為更多患者帶來突破性的治療方案。TE-8214與市售長效型奧曲肽類藥物的差異化比較（圖／免疫功坊提供。）關於免疫功坊免疫功坊位於國家生技研究園區，專注於開發結合標的 (T) 與效應(E) 結構單元的「T-E型藥物」，以實現兼具療效與安全性的突破性治療。公司運用自主研發的「脂肪酸束平台」技術，目前已有兩項新藥進入臨床階段，並有多項臨床前候選藥物，未來將持續推進創新藥物研發與臨床應用。聯絡資訊若您有合作洽談需求或欲了解更多資訊，歡迎與我們聯繫。電子郵件：bd@immunwork.com公司官網：https://www.immunwork.com/公司影片：https://www.youtube.com/watch?v=1owxqn08HoQT-E Pharma's subsidiary Immunwork Announces Positive Phase I Top-Line Data for TE-8214, a Next-Generation Long-Acting Octreotide, Demonstrating Favorable Safety, Tolerability, and Potent IGF-1 Suppression.·Pioneering Patient Experience: TE-8214, a highly water-soluble aqueous solution, enables pain-free subcutaneous injection with a thin 30G needle, eliminating injection site reactions seen with current therapies.·Strong Pharmacodynamic Activity: Robust, dose-dependent reduction of disease biomarker IGF-1, with 83% of high-dose participants achieving a >20% reduction, confirming therapeutic potential.·Significant Market Potential: Positioned for the US$10 billion long-acting octreotide market by addressing key unmet needs of painful injections and side effects associated with current viscous, thick-needle formulations.·Phase II Initiation and Strategic Partnering: Phase II trial planned for Q3 2025; Immunwork is actively seeking strategic collaborations to accelerate global development and commercialization.Immunwork, Inc., a clinical-stage biotechnology company developing transformative therapies, today announced positive top-line results from its Phase I clinical trial (in Australia) of TE-8214, a novel long-acting octreotide analog for the treatment of acromegaly and neuroendocrine tumors (NETs). The study met its primary objectives: TE-8214 demonstrated good safety, tolerability, and pharmacological activity, with pain-free subcutaneous administration and no injection site reactions.（This photo provided by Immunwork, Inc.）A Next-Generation Therapy for Unmet Patient NeedsTE-8214 was developed using Immunwork's proprietary fatty acid modification platform, which extends the drug's half-life and increases water solubility. TE-8214's water-soluble, low-viscosity formulation allows for subcutaneous administration with a fine 30G needle, offering a dramatically improved patient experience compared to the current standard-of-care, which requires thick, viscous formulations administered with large 19G or 20G needles that often cause significant pain and injection site reactions. This innovation addresses a critical need for safer, more patient-friendly long-acting therapies in a global octreotide market projected to reach US$10 billion by 2030.（This photo provided by Immunwork, Inc.）Phase I Clinical Highlights TE-8214's Differentiated ProfileThe randomized, double-blind, placebo-controlled, single-ascending dose study enrolled 32 healthy subjects (24 receiving TE-8214 and 8 receiving saline) across four dose cohorts (0.6, 1.2, 2, and 4 mg). Exceptional Safety and Tolerability: TE-8214 was well tolerated with no serious adverse events reported. Notably, no TE-8214 recipients experienced injection site pain or nodules—results identical to placebo with saline — demonstrating a clear advantage over existing therapies. Gastrointestinal side effects, often seen with octreotide, were minimal: only 3 of 24 TE-8214 recipients reported very mild gastrointestinal discomfort. Potent and Sustained Pharmacodynamic Activity: Octreotide drugs mainly exert their therapeutic effects by suppressing insulin-like growth factor 1 concentration in the body. In the two highest dose cohorts (2 mg and 4 mg), 10 of 12 participants (83%) achieved a >20% reduction in insulin-like growth factor 1, confirming robust biological activity and validating its therapeutic potential for Phase II studies.“These Phase I clinical trial results confirm TE-8214's differentiated profile: TE-8214 is highly water-soluble, can be administered subcutaneously using a fine needle, significantly reducing injection pain and side effects for patients,” said Dr. Tse-Wen Chang, founder and CEO of Immunwork and a pioneer of anti-CD3 (OKT3) and the inventor of anti-IgE (Xolair) for asthma and allergy. “By solving the fundamental formulation and administration challenges of current treatments, we have created a product with the potential to become the new standard of care. TE-8214's profile—combining ease of administration, superior tolerability, and strong efficacy—positions it to capture a significant share of the market and, most importantly, vastly improve the quality of life for patients.”Strategic Outlook: Advancing to Phase II and Seeking Partnerships Immunwork is preparing for a Phase II trial of TE-8214 in Taiwan, planned to start in Q3 2025, to further evaluate the efficacy and safety of TE-8214 in patients. The company is actively pursuing strategic partnerships with pharmaceutical leaders to accelerate late-stage clinical development, navigate global regulatory pathways, and maximize the commercial potential of TE-8214.TE-8214: A Differentiated Profile vs. Marketed Long-acting Octreotide Analogs.（This photo provided by Immunwork, Inc.）About ImmunworkImmunwork, based in the National Biotechnology Research Park in Taipei, develops "T-E type drugs" that combine targeting (T) and efficacy (E) moieties for transformative therapies with enhanced efficacy and safety.
