Avedro Announces Resubmission of New Drug Application to FDA for Corneal Cross-Linking

Waltham, Massachusetts, USA, Sep 30, 2014

Avedro Inc., a Boston-based ophthalmic medical device and pharmaceutical company announces today that it resubmitted its New Drug Application (NDA) for riboflavin ophthalmic solution/KXL® System to the U.S. Food and Drug Administration (FDA). Avedro anticipates an application action date (PDUFA) in March 2015. This resubmission is a comprehensive reply to questions and requests from the March 2014 complete response letter.

The proposed indications of treatment of progressive keratoconus or corneal ectasia following refractive surgery were both granted orphan status by the FDA in 2011. Patients with these sight threatening conditions may require corneal transplant surgery. If approved, riboflavin ophthalmic solution/KXL System would be the first FDA approved therapeutic treatment for these orphan indications, and entitle Avedro to seven years of US market exclusivity.

“US ophthalmic surgeons are pleased to hear of this next step in the process with the FDA,” said Peter Hersh, MD, Hersh Vision Group, Teaneck, NJ and Avedro Medical Monitor. “Cross-linking represents an important treatment option that addresses an unmet medical need. US patients and their ophthalmologists eagerly await the availability of corneal cross-linking.”

“We have been working closely with the FDA to address the issues raised in the complete response letter. We are very pleased to be able to resubmit the NDA and answer the questions that were posed to the Company,” said David Muller, PhD, CEO of Avedro. “Treatment for keratoconus and corneal ectasia represents an important step for Avedro as we work to develop a full portfolio of corneal cross-linking treatments.”

New Corneal Layer Identified

In a report published in the academic journal Ophthalmology researchers revealed they’ve found a new layer to the human eye. Named Dua’s layer, after Professor Harminder Dua from the University of Nottingham in the U.K. who discovered it, the previously undetected sixth layer of the cornea located towards the back of cornea, between the corneal stroma and the Descemet’s membrane. While the entire cornea is around 550 microns thick (0.5mm), the new layer is just around 15 microns thick and has proved to be incredibly strong and tough which enables it to withstand about one and a half to two bars of pressure.
