What is Pegaptanib
Pegaptanib is a polynucleotide aptamer. Pegaptanib specifically binds to VEGF 165, a protein that plays a critical role in angiogenesis (the formation of new blood vessels) and increased permeability (leakage from blood vessels), two of the primary pathological processes responsible for the vision loss associated with neovascular AMD.[Wikipedia]
Pegaptanib mechanism of action
Pegaptanib sodium is a pegylated aptamer, a modified oligonucleotide, which adopts a three- dimensional conformation that enables it to bind to extracellular VEGF with high affinity and selectivity. Pegaptanib sodium binds to the major pathological VEGF isoform, extracellular VEGF165, with high affinity (Kd = 200 pM) and specificity, thereby inhibiting VEGF165 binding to its VEGF receptors. In contrast virtually no binding of the non-pegylated aptamer to VEGF121 or the VEGF -related proteins VEGF-B, VEGF-C and placental growth factor (PlGF) was detected using invitro filter binding assays. Pegaptanib sodium does not bind significantly to VEGF121. In animal models, VEGF164 (the rodent counterpart of human VEGF165) was specifically upregulated in disease. The selective inhibition of VEGF164 with pegaptanib sodium proved as effective at suppressing pathological neovascularization as pan-VEGF inhibition7, however pegaptanib sodium spared the normal vasculature whereas pan-VEGF inhibition did not.

Toxicity of Pegaptanib
It is not known if pegaptanib is safe in pregnant women or if it is excreted in breast milk. Likewise, no studies have been done in the pediatric population. Most adverse events elated to the drug are ocular however non-ocular adverse events related to the drug or the injection procedure also occurred, among which headaches and rhinorrhoea appeared in more than 1% of patients. Pegaptanib is contraindicated when the patient has an ocular or periocular infection.
