氣喘:新型療法、未滿足的需求和TPP洞察報告,2026年Asthma - Emerging Therapy, with Unmet Needs and TPP Insights Report - 2026 |

Thelansis 的「氣喘:新興療法、未滿足的需求和目標產品概況 (TPP) 洞察報告 - 2026」對該適應症的關鍵新興療法和主要藥物發現機會進行了全面分析,包括新興的競爭格局、未滿足的需求、目標產品概況 (TPP)、試驗設計和關鍵意見領袖 (KOL) 的見解。
氣喘是一種慢性發炎性氣道疾病,其特徵是可變且可逆的氣流阻塞、支氣管高反應性和氣道重塑。其病理生理機制以Th2介導的嗜酸性粒細胞發炎為中心(主要由2型細胞激素IL-4、IL-5和IL-13驅動),並且由於氣喘具有顯著的生物學異質性,也觀察到非嗜酸性粒細胞粒細胞性、嗜中性白血球和混合表現型。遺傳易感性、過敏原致敏、呼吸道病毒感染疾病、職業暴露和肥胖交互作用,成為此疾病的主要決定因素。患者表現為陣發性喘息、呼吸困難、胸悶和咳嗽,這些症狀往往在夜間加重,並由特定因素誘發。肺功能檢查顯示可逆性阻塞模式,支氣管擴張劑的療效可確診氣喘。呼氣一氧化氮 (frNO) 和血清嗜酸性粒細胞計數是 2 型發炎負荷的指標。治療遵循 GINA(全球氣喘和支氣管炎舉措)框架,這是一種逐步治療方案,優先控制症狀和預防急性發作。吸入性糖皮質激素仍是治療的基礎,長效型BETA2受體激動劑、白三烯受體拮抗劑和長效毒蕈鹼受體拮抗劑可作為輔助藥物。生物製藥(度普利尤單抗、美泊利單抗、貝那利珠單抗、替澤帕魯單抗)透過靶向特定的發炎通路,徹底改變了重症和難治性 2 型氣喘的治療。過敏原免疫療法對過敏表現型具有緩解疾病作用。定期後續觀察、最佳化吸入技術、避免誘發因素以及製定個人化的行動計畫是長期管理的基礎。只要堅持治療,預後通常良好,但嚴重的、控制不佳的氣喘會帶來較高的發病率和死亡率風險。
Thelansis's "Asthma Emerging Therapy, with Unmet Needs and TPP Insights Report - 2026" provides a comprehensive analysis of the emerging competitive landscape, unmet needs, target product profiles (TPPs), trial designs, and KOL insights on key emerging therapies and key drug development opportunities in the indication.
Asthma is a chronic inflammatory airway disease characterised by variable, reversible airflow obstruction, bronchial hyperresponsiveness, and airway remodelling, driven predominantly by Th2-mediated eosinophilic inflammation - with type 2 cytokines IL-4, IL-5, and IL-13 central to its pathobiology - alongside non-eosinophilic neutrophilic and mixed phenotypes recognising asthma's considerable biological heterogeneity. Genetic susceptibility, allergen sensitisation, respiratory viral infections, occupational exposures, and obesity interact as key disease determinants. Patients present with episodic wheeze, dyspnoea, chest tightness, and cough - characteristically worse nocturnally and with triggers - with spirometry demonstrating reversible obstructive pattern and bronchodilator responsiveness confirming diagnosis; fractional exhaled nitric oxide and blood eosinophil counts guide type 2 inflammatory burden assessment. Management follows a stepwise GINA framework prioritising symptom control and exacerbation prevention; inhaled corticosteroids remain the therapeutic cornerstone, with long-acting beta-agonists, leukotriene receptor antagonists, and long-acting muscarinic antagonists as add-on therapies. Biologic agents - dupilumab, mepolizumab, benralizumab, and tezepelumab - have transformed severe, refractory type 2 asthma management by targeting specific inflammatory pathways. Allergen immunotherapy offers disease modification in allergic phenotypes. Regular review, inhaler technique optimisation, trigger avoidance, and personalised action plans underpin long-term management; prognosis is generally favourable with treatment adherence, though severe uncontrolled asthma carries significant morbidity and mortality risk.
