伊普可泮的作用機制為特異性結合因子B,抑制C3轉化酶前體(C3bB)的形成,從而阻斷補體級聯(lián)反應的放大,最終減少膜攻擊復合物(MAC)的生成及細胞溶解。該藥是全球首個口服補體因子B抑制劑,目前獲批用于治療陣發(fā)性夜間血紅蛋白尿(PNH)——一種罕見的補體介導的慢性血液疾病,此前治療依賴靜脈注射抗C5抗體(如依庫珠單抗)。
伊普可泮通過精準調(diào)控補體旁路激活,可潛在應用于年齡相關性黃斑變性、非典型溶血尿毒綜合征及C3腎小球病等多種補體相關疾病,相關適應癥尚在臨床開發(fā)中。其口服給藥方式顯著提升患者用藥便利性,成為補體靶向治療領域的重要突破。
KD: 7.9 nM (factor B)
IC50: 10 nM (factor B)
Iptacopan (LNP023) demonstrates potent inhibition of alternative complement pathway (AP)-induced membrane attack complex (MAC) formation in 50% human serum (IC
50
value of 130 nM).
Iptacopan (LNP023) exhibits excellent selectivity over other proteases affording IC
50
values of >30 μM across a panel of 41 human proteases, including the AP protein factor D (>100 μM).
Iptacopan (LNP023; 20-180 mg/kg; oral administration) prevents KRN (150 μL)-induced arthritis in mice and is effective upon prophylactic and therapeutic dosing in an experimental model of membranous nephropathy in rats.
LNP023 exhibits moderate half-lives (T
1/2
; Wistar Han rats 3.4 h, beagle dogs 5.5 h) and C
max
(Wistar Han rats 410 nM, beagle dogs 2200 nM) following oral administration (rat 30 and, dog 10 mg/kg).
Iptacopan exhibits terminal elimination half-lives (T
1/2
; Wistar Han rats 7 h, beagle dogs 5.6 h) due to high plasma clearance (8, and 2 mL/min/kg respectively combined with large volumes of distribution (2.3, and 0.6 L/kg respectively) following intravenous administration (rat 1.0 and, dog 0.1 mg/kg).
| Animal Model: | C57BL/6 mice with KRN-induced arthritis |
| Dosage: | 20, 60, and 180 mg/kg |
| Administration: | Orally gavaged; twice a day (b.i.d.) for 14 days |
| Result: | Blocked KRN-induced arthritis. |
