“The treatment paradigms for many significant diseases of the eye such as glaucoma, AMD, and diabetic macular edema are in the midst of a revolutionary change. The need for access to the specific locations within the eye where these diseases occur is paramount to improving patient outcomes. The iTrack™ microcatheter uniquely provides such site-specific access, thus enabling an exciting new generation of medical therapies.” stated Michael F. Nash, President and CEO of iScience Interventional, Inc. “We believe that these sight specific treatments will represent a dramatic step forward in patient care, while providing a valuable benefit to both private healthcare providers and public healthcare systems.”

Glaucoma and retinal diseases represent the two most underserved clinical needs within ophthalmology. The Company has received FDA 510k clearance and CE Mark for the iTrack Canaloplasty Microcatheter™, which is used by glaucoma specialists for lowering intraocular pressure in patients with open angle glaucoma. Additionally, clinical studies are currently in progress in Europe to evaluate microcatheter-based delivery of drugs for the treatment of wet-AMD in patients non-responsive to current intravitreal therapies. The interim results of these studies are expected to be published later this year.
