Aganirsen eye drops demonstrated significant benefits among patients with keratitis, as well as in patients with viral keratitis and central neovascularization, according to the results of a recent study.

The multicenter, double-masked, phase 3 study included 69 patients with keratitis-related progressive corneal neovascularization who were randomized to use either aganirsen drops (86 µg/day/eye) or placebo twice per day for 90 days. Patients were then followed for up to 180 days.

There were no significant differences in visual acuity between aganirsen patients and placebo patients at 90 days, according to the researchers; however, patients in the aganirsen group had a significant drop in the relative corneal neovascularization area after 90 days (26.2%; P = .014). The researchers noted a continued improvement of 26.67% after 180 days (P = .012).

By day 180, patients with viral keratitis and central neovascularization who used aganirsen showed a significant decrease in the need for transplantation compared with patients who used placebo (P = .048). Additionally, although there were no significant differences between the treatment groups with regard to graft rejection risk, use of aganirsen drops tended to decrease said risk by day 90, according to the researchers.

“Further studies focusing on these patients are necessary to support and confirm the novel concept in which the need for corneal transplantation could be decreased by adding an anti-angiogenic therapy to conventional antiviral therapy in herpetic keratitis,” the researchers concluded.
