SEATTLE, March 29, 2012 /PRNewswire/ -- Omeros Corporation (NASDAQ: OMER) today reported the allowance by the US Patent and Trademark Office (USPTO) of an additional patent claiming intraocular surgical methods of using OMS302, the Company's ophthalmological PharmacoSurgery product. The issued patent will have a term extending through July 2023. Currently in Phase 3 clinical development, OMS302 is designed to maintain intraoperative mydriasis (pupil dilation) and reduce pain in the early postoperative period in patients undergoing intraocular lens replacement surgery, including cataract surgery and refractive lens exchange.
This patent extends coverage for OMS302 and further expands Omeros' established PharmacoSurgery intellectual property portfolio. The drug product demonstrated statistically significant superiority over placebo in maintenance of intraoperative mydriasis and reduction of pain in Omeros' Phase 2b clinical trial and first Phase 3 clinical trial. These positive data played a role in the USPTO's decision. Omeros plans to begin enrolling patients next month in its second OMS302 Phase 3 clinical trial.
Omeros is building a patent portfolio for OMS302 focused on protecting both the drug product's composition and method of use. Omeros currently is preparing additional patent applications directed to OMS302 that, if allowed, would further extend its patent protection until at least 2033.
About Omeros' OMS302 Program
OMS302 is Omeros' product being developed for use during intraocular lens replacement (ILR) surgery, including cataract surgery and refractive lens exchange. OMS302 is a proprietary combination of ketorolac, an anti-inflammatory agent, and phenylephrine, a mydriatic (pupil dilating) agent. FDA-approved drugs containing each of these agents have been used in ophthalmological clinical practice for more than 15 years, and both are contained in generic, FDA-approved drugs.
ILR surgery involves replacement of the original lens of the eye with an artificial intraocular lens. These procedures are typically performed to replace a lens opacified by a cataract or to correct a refractive error of the lens (i.e., refractive lens exchange). OMS302 is added to standard irrigation solution used in ILR surgery and delivered intracamerally to maintain intraoperative mydriasis (pupil dilation), to prevent surgically induced miosis (pupil constriction), and to reduce postoperative pain and irritation. Maintenance of mydriasis is critical to the safety and surgical ease of the procedure. Intraoperative pupil constriction increases the risk of injury to intraocular structures and can substantially prolong surgical time.
