- Background
Avacincaptad pegol is an RNA aptamer covalently bound to a branched polyethylene glycol (PEG) molecule. It was developed to treat an advanced form of age-related macular degeneration (AMD) called geographic atrophy (GA).4 AMD is the leading cause of vision loss in developed countries for people over 50 years old, with a global estimate of 170 million individuals affected. AMD eventually progresses to bilateral and irreversible loss of vision, whether or not the patients have the non-neovascular (dry) or the neovascular (wet) form of AMD.2 Although anti-VEGF therapy is available for the neovascular form of AMD, no treatment was approved for GA.2
Avacincaptag pegol was approved by the FDA on August 4, 2023, under the brand name IZERVAY for the treatment of GA secondary to AMD. This approval is based on the positive results obtained from 2 phase 3 clinical trials GATHER1 and GATHER2.5

- Pharmacodynamics
Complement C5 is cleaved into C5a and C5b, and it is the final step of the complement cascade where a membrane attacking complex (MAC) is formed to cause cell death.1,2 This is thought to be a major contributor to the pathophysiology of age-related macular degeneration (AMD), as immunohistochemical studies demonstrated complement deposition in postmortem eyes of patients diagnosed with AMD.2 Additionally, 50% of patients with AMD were also found to have mutations in genes regulating the complement cascade, further implicating this pathway in deteriorating retinal health.2 By inhibiting the cleavage of complement C5, avacincaptad pegol can dampen the inflammatory processes, thus slowing down retinal cell injuries and degeneration.2
Increased geographic atrophy area (GA) growth is reflective of the loss of photoreceptors and AMD disease progression, and reductions in the rate of geographic atrophy growth were observed from baseline through the first year of treatment across avacincaptad pegol treatment groups in studies GATHER1 and GATHER2.4 Specifically, a GA growth rate reduction of 29% was observed in patients receiving avacincaptad pegol monthly or 20% in patients receiving the treatment every other month.3
- Mechanism of action
Avacincaptad pegol is an RNA aptamer, a PEGylated oligonucleotide that binds to and inhibits complement protein C5. By inhibiting C5, avacincaptad pegol may prevent its cleavage to C5a and C5b thus decreasing membrane attack complex (MAC) formation.4
Target Actions Organism AComplement C5 inhibitorHumans - Absorption
Following a single dose of avacincaptad pegol, maximum avacincaptad pegol plasma concentrations (Cmax) are estimated to occur approximately 7 days post-dose and mean (CV%) free avacincaptad pegol plasma Cmax is estimated to be 68.4 ng/mL (57.8%) in neovascular AMD (nAMD) patients. The AUC0-28 days following a single 2 mg dose is 1064 day∙ng/mL. Based on a population pharmacokinetic analysis of patients with nAMD, the predicted steady-state avacincaptad pegol Cmax is 83.9 ng/mL after monthly intravitreal administration of avacincaptad pegol 2 mg.4
In humans, avacincaptad pegol plasma concentrations are predicted to be approximately 7,000-fold lower than vitreal concentrations.4
- Volume of distribution

- Protein binding
Limited information is available on the protein binding of avacincaptad pegol
- Metabolism
The metabolism of avacincaptad pegol has not been fully characterized. Avacincaptad pegol is expected to be catabolized by endonucleases and exonucleases to oligonucleotides of shorter lengths.4
- Route of elimination
The elimination of avacincaptad pegol has not been fully characterized. Avacincaptad pegol is expected to be catabolized by endonucleases and exonucleases to oligonucleotides of shorter lengths which may be excreted renally, in a similar manner to the elimination of endogenous RNA.4
- Half-life
The estimated apparent systemic half-life of avacincaptad pegol is approximately 12 days.4

- Toxicity
There are no adequate and well-controlled studies of IZERVAY administration in pregnant women. The use of IZERVAY may be considered following an assessment of the risks and benefits.4
The administration of avacincaptad pegol to pregnant rats and rabbits throughout the period of organogenesis resulted in no evidence of adverse effects on the fetus or pregnant female at intravenous (IV) doses 5.1 times and 3.2 times the human exposure (based on AUC) at the maximum recommended human dose (MRHD) of 2 mg once monthly, respectively.4
No studies have been conducted on the carcinogenic potential of avacincaptad pegol.4
Avacincaptad pegol was negative in in vitro (bacterial reverse mutation assay, chromosomal aberration in mammalian cells) and in vivo (mouse bone marrow micronucleus) assays.4
