皰疹性角膜炎(HK):新型療法、未滿足的需求和TPP洞察報告,2026年Herpetic Keratitis (HK) - Emerging Therapy, with Unmet Needs and TPP Insights Report - 2026 |

Thelansis 的「皰疹性角膜炎 (HK):新型療法、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治療方法和主要藥物開發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)、臨床試驗設計以及關鍵意見領袖 (KOL) 的見解。
皰疹性角膜炎(HK)是全球導致角膜盲的主要感染性病因之一,主要由1型單純皰疹病毒(HSV-1)引起,少數情況下由2型單純皰疹病毒(HSV-2)引起。初次眼部感染疾病後,病毒在三叉神經節內建立潛伏狀態,並重新運作,導致進行性性角膜損傷。其病理生理機制包括病毒對角膜上皮細胞的直接損傷以及免疫介導的基質炎症,從而導致以下特徵性臨床表現:上皮性角膜炎(螢光素染色顯示病因特異性的樹枝狀或地圖狀潰瘍)、基質性角膜炎、內皮炎和神經營養性角膜病,每種表現的治療方法各不相同。患者通常表現為單側眼痛、畏光、流淚、視力下降和角膜感覺減退。角膜感覺減退是皰疹病毒引起的角膜炎的典型特徵。診斷主要依據臨床觀察,並輔以裂隙燈顯微鏡檢查。對於非典型症狀,可透過角膜或房水檢體的PCR檢測確診。對於上皮性病變,局部抗病毒藥物(更昔洛韋凝膠或阿昔洛韋軟膏)是首選治療方案。然而,對於基質性角膜炎,應謹慎使用局部類固醇,並合併預防性抗病毒治療,以抑制免疫介導的損傷。對於頻繁復發的患者,口服阿昔洛韋或伐昔洛韋的預防性治療可顯著降低復發頻率。對於難治性病例,若疤痕嚴重影響視力,則需進行角膜移植。復發頻率越高,預後越差。長期抗病毒治療、對患者進行復發誘因教育以及定期眼科後續觀察對於維持角膜健康和視覺功能至關重要。
Thelansis's "Herpetic Keratitis (HK) 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.
Herpetic keratitis (HK) is a leading infectious cause of corneal blindness worldwide, caused predominantly by herpes simplex virus type 1 (HSV-1) - and less commonly HSV-2 - following primary ocular infection and subsequent latency establishment within the trigeminal ganglion, with recurrent reactivation driving progressive corneal damage. The pathophysiology involves both direct viral cytopathic injury to corneal epithelium and immune-mediated stromal inflammation, producing distinct clinical entities: epithelial keratitis - characterised by pathognomonic dendritic or geographic ulcers on fluorescein staining - stromal keratitis, endotheliitis, and neurotrophic keratopathy, each carrying distinct management implications. Patients present with unilateral eye pain, photophobia, lacrimation, blurred vision, and reduced corneal sensation - the latter a hallmark of herpetic aetiology. Diagnosis is primarily clinical, supported by slit-lamp biomicroscopy; PCR of corneal or aqueous samples confirms diagnosis in atypical presentations. Topical antivirals - ganciclovir gel or acyclovir ointment - are first-line for epithelial disease, while stromal keratitis requires judicious topical corticosteroids alongside antiviral cover to suppress immune-mediated injury. Oral acyclovir or valacyclovir prophylaxis significantly reduces recurrence frequency in patients with frequent relapses. Corneal transplantation addresses visually significant scarring in refractory cases. Prognosis worsens with recurrence frequency; long-term antiviral suppression, patient education regarding recurrence triggers, and regular ophthalmological surveillance are integral to preserving corneal integrity and visual function.
