Avedro Announces Receipt of Complete Response Letter from FDA for Corneal Cross-Linking NDA

WALTHAM, Mass.--(BUSINESS WIRE)--Avedro Inc., a Boston-based ophthalmic medical device and pharmaceutical company announces that it received a complete response letter from the U.S. Food and Drug Administration (FDA) regarding the New Drug Application (NDA) for their riboflavin ophthalmic solution/KXL® System. In the complete response letter the agency identified a number of areas of the application which require additional information.

“We plan on working closely with the FDA to resolve these issues as quickly as possible to make this important treatment available to patients in the US,” said David Muller, PhD, CEO of Avedro. “While we do not yet have an estimate on how long it will take to resolve the issues, we are confident that we can adequately answer their questions. However, we continue to grow internationally by bringing advanced corneal cross-linking procedures to ophthalmologists and patients around the world. This expansion also includes the development and refinement of our KXL II™ system for Photorefractive Intrastromal Cross-Linking (PiXL™).”

Keratoconus, an orphan indication, is a potentially blinding disease, for which limited therapeutic treatment is available in the US. Corneal ectasia is a rare outcome of refractive surgery (such as LASIK) and is a progressive condition that is difficult to manage. Patients with these sight threatening conditions may require corneal transplant surgery. If approved, the riboflavin ophthalmic solution/KXL System would be the first FDA approved therapeutic treatment for these orphan indications.
