TAMPA, Fla., Jan. 26 /PRNewswire/ -- Sirion Therapeutics, Inc., a privately held ophthalmic-focused biopharmaceutical company, today announced that its New Drug Application (NDA) for ganciclovir ophthalmic gel, 0.15%, has been accepted for review by the U.S. Food and Drug Administration (FDA). Sirion Therapeutics is seeking approval for ganciclovir as a treatment for herpetic keratitis, an ocular disease caused by the herpes simplex virus.

To assess the efficacy and safety of ganciclovir, four randomized, multicenter trials compared ganciclovir gel, 0.15%, with acyclovir ointment, 3%, both of which are used as first-line therapies outside the U.S. to treat herpetic keratitis. The studies found that ganciclovir is as effective as acyclovir and that the tolerability of ganciclovir was superior to acyclovir, particularly with regard to blurring and stinging or burning sensations after instillation. Additionally, since ganciclovir is formulated as an aqueous gel, it allows for prolonged contact time with the corneal surface.
"Based upon its proven safety and efficacy, the introduction of a new topical antiviral agent with improved tolerability, such as ganciclovir ophthalmic gel, would clearly be a
