Identification
- Name
- Aflibercept
- Accession Number
- DB08885
- Description
Aflibercept is a recombinant protein composed of the binding domains of two human vascular endothelial growth factor (VEGF) receptors fused with the Fc region of human immunoglobulin gamma 1 (IgG1). Structurally, Aflibercept is a dimeric glycoprotein with a protein molecular weight of 96.9 kilo Daltons (kDa). It contains approximately 15% glycosylation to give a total molecular weight of 115 kDa. All five putative N-glycosylation sites on each polypeptide chain predicted by the primary sequence can be occupied with carbohydrate and exhibit some degree of chain heterogeneity, including heterogeneity in terminal sialic acid residues, except at the single unsialylated site associated with the Fc domain. Aflibercept, as an ophthalmic agent, is used in the treatment of macular edema following Central Retinal Vein Occlusion (CRVO) and neovascular Age-Related Macular Degeneration (AMD). Ziv-aflibercept, under the brand name Zaltrap, was developed as an injection for treatment of metastatic colorectal cancer. FDA approved in November 18, 2011 and EMA approved in November 2012.

Pharmacology
- Indication
The opthalmic agent is used for the treatment of neovascular (wet) age-related mascular degeneration (AMD) and macular edema following central retinal vein occulsion (CRVO). The systemic injection, known as ziv-aflibercept, in combination with 5-fluorouracil, leucovorin, irinotecan-(FOLFIRI), is for the treatment of metastatic colorectal cancer that is resistant to or progressed following treatment with oxaliplatin.

Learn More- Pharmacodynamics
Compared to other anti-VEGF drugs like bevacizumab and ranibizumab, aflibercept has a higher binding affinity to VEGF-A (Kd = 0.5 pM).
- Mechanism of action
Ablibercept is a recombinant fusion protein that acts as a decoy receptor for the ligands, vascular endothelial growth factor-A (VEGF-A) and placental growth factor (PIGF). It prevents these ligands to binding to endothelial receptors, VEGFR-1 and VEGFR-2, to suppress neovascularization and decrease vascular permeability. This ultimately will slow vision loss or the progression of metastatic colorectal cancer.
Target Actions Organism AVascular endothelial growth factor A binderHumans APlacenta growth factor binderHumans AVascular endothelial growth factor B binderHumans - Absorption
In patients with wet AMD and CRVO, the mean peak plasma concentration (Cmax) was 0.02 mcg/mL and 0.05 mcg/mL respectively. These concentrations were reached in 1 to 3 days. Aflibercept did not accumulate when administered as repeated doses intravitreally every 4 weeks.
- Volume of distribution
After intravenous injection of aflibercept, the volume of distribution is 6 L.
- Protein binding
- Not Available
- Metabolism
Because aflibercept is a protein, it is expected to be broken down via proteolysis into smaller peptides and amino acids. The cytochrome P450 enzyme system is not involved in the metabolism of aflibercept.
- Route of elimination
Via kidney and liver
- Half-life
Intravitreal half-life= 7.13 days in humans; Terminal elimination half-life of free aflibercept in plasma was 5 to 6 days after IV injection of 2 - 4 mg/kg dose.
- Clearance
When cancer patients were given 2-9 mg/kg every 2 or 3 week; 1 hour IV infusion of aflibercept the typical estimated clearances were as follows: CL of free aflibercept (CLf) = 0.88 L/day; CL of bound aflibercept (CLf) = 0.19 L/day; Patients clear free aflibercept faster if they had low albumin or high alkaline phosphatase levels.

Learn More- Toxicity
For all intravitreal VEGF inhibitors, there is increased risk of stroke and myocardial infarction. An increase in intraocular pressure may also occur. When used intravenously, most common adverse reactions were leukopenia, diarrhea, neutropenia, proteinuria, AST increased, stomatitis, fatigue, thrombocytopenia, ALT increased, hypertension, weight decreased, decreased appetite, epistaxis, abdominal pain, dysphonia, serum creatinine increased, and headache.
