重癥肌無力（Myasthenia Gravis, MG）是一種罕見的慢性自身免疫性神經(jīng)肌肉疾病，由致病性免疫球蛋白G（IgG）抗體攻擊神經(jīng)肌肉接頭突觸后成分（如乙酰膽堿受體AChR、肌肉特異性酪氨酸激酶MuSK等）引發(fā)，導(dǎo)致神經(jīng)信號傳遞障礙，臨床表現(xiàn)為波動性肌無力和易疲勞性，常累及眼肌、延髓肌及肢體肌肉，嚴(yán)重時(shí)可致呼吸衰竭。約85%的患者為全身型（gMG），其中AChR抗體陽性占主導(dǎo)（80%），MuSK抗體陽性者癥狀更重。該病發(fā)病機(jī)制涉及抗體介導(dǎo)的補(bǔ)體激活（如C5介導(dǎo)膜攻擊復(fù)合物形成）及FcRn受體對致病性IgG的再循環(huán)維持，導(dǎo)致持續(xù)自身免疫損傷。
重癥肌無力（MG）的藥物研發(fā)進(jìn)展近年來聚焦于靶向致病抗體清除和補(bǔ)體通路調(diào)控兩大核心機(jī)制，形成了以FcRn抑制劑和補(bǔ)體C5抑制劑為主流的治療格局：
● FcRn靶點(diǎn)藥物通過阻斷FcRn-IgG結(jié)合加速致病抗體降解，成為當(dāng)前最活躍的研發(fā)方向。代表藥物包括艾加莫德（efgartigimod，全球首款FcRn抑制劑）、羅澤利昔珠單抗（rozanolixizumab，2025年3月國內(nèi)獲批）、尼卡利單抗（nipocalimab，2025年4月FDA獲批）等。
● 補(bǔ)體C5抑制劑則通過阻斷補(bǔ)體級聯(lián)末端減少膜攻擊復(fù)合物形成，代表藥物為瑞利珠單抗（ravulizumab，2025年4月國內(nèi)獲批）。
未來重癥肌無力（MG）的藥物將從廣譜免疫抑制向精準(zhǔn)靶向演進(jìn)，F(xiàn)cRn與C5抑制劑已占據(jù)當(dāng)前創(chuàng)新藥的67%，而雙靶點(diǎn)藥物及無需化療的CAR-T療法有望進(jìn)一步突破難治性患者治療瓶頸。
