Avacincaptad pegol
Based on 1 Customer Validation
Avacincaptad pegol (Izervay) is a selective inhibitor targeting complement component C5, and is a pegylated ribonucleic acid aptamer. Avacincaptad pegol inhibits the cleavage of C5 into pro-inflammatory C5a and C5b, which forms the membrane attack complex (C5b-9), thereby reducing inflammatory cell recruitment and retinal cell damage. Avacincaptad pegol can slow the growth of geographic atrophy (GA) lesions and reduce the risk of persistent vision loss. Avacincaptad pegol can be used in research of geographic atrophy associated with age-related macular degeneration (AMD) and has been approved by the FDA.

生物活性
|
C5 |
Avacincaptad pegol exerts its complement inhibitory activity by specifically binding to complement component C5, inhibiting its cleavage into pro-inflammatory C5a and C5b, which forms the membrane attack complex (MAC), thus blocking the terminal steps of the complement cascade[1].
Avacincaptad pegol can inhibit the damage to retinal pigment epithelial (RPE) cells caused by the complement activation product C5b-9, reduce lysosomal overload and the release of pro-inflammatory factors, maintain the stability of RPE cell function, and is associated with the improvement of pathological processes related to age-related macular degeneration (AMD)[1].

Animal Model:Cynomolgus macaques (Macaca fascicularis) (male, 2.9-6.6 kg, 3.4-5.0 years old) sodium iodate-induced dry age-related macular degeneration (AMD) with geographic atrophy (GA) model[2]
-
Dosage:Initial 1.5 mg/eye ubsequent doses adjusted to 1 mg/eye (phosphate-buffered saline)
-
Administration:16 weeks
-
Result:The mean GA area in Avacincaptad pegol-treated eyes (11.4 ± 4.0 mm2) was reduced by approximately 36% compared with vehicle-treated eyes (18.9 ± 6.6 mm2), though the difference was not statistically significant.
Avacincaptad pegol did not alter the thinning of total retinal thickness or central macular thickness induced by sodium iodate. No choroidal neovascularization (CNV) was observed in either the treatment or vehicle group.
Choroidal capillary (CC) leakage under or around the macula was detected in both groups, with no statistically significant difference in the incidence of CC leakage between the two groups.
