-- Initiates International Market Expansion --

SEATTLE--(BUSINESS WIRE)--May 10, 2016-- Omeros Corporation (NASDAQ: OMER), a biopharmaceutical company committed to discovering, developing and commercializing both small-molecule and protein therapeutics for large-market as well as orphan indications targeting inflammation, coagulopathies and disorders of the central nervous system, today announced entry into an exclusive supply and distribution agreement for the sale of OMIDRIA (phenylephrine and ketorolac injection) 1% / 0.3% in the Kingdom of Saudi Arabia, the United Arab Emirates and other countries in the Middle East with ITROM Trading Drug Store (ITROM). ITROM is Dubai-based and an internationally recognized pharmaceutical marketing and distribution company specializing in ophthalmology. Under the agreement, ITROM will be responsible for obtaining marketing authorizations for OMIDRIA within the licensed territory and for marketing, selling and distributing product supplied by Omeros. Existing ophthalmology medical sales representatives employed by ITROM are expected to be reinforced with additional medical sales representatives that will be dedicated to OMIDRIA.

“We expect that ITROM will begin sales of OMIDRIA later this year,” said Gregory A. Demopulos, M.D., chairman and chief executive officer of Omeros. “This marks the start of our expansion to international markets, and we look forward to bringing the benefits of OMIDRIA to patients outside of the U.S.”

“ITROM and our affiliate companies have been successfully representing innovative and breakthrough products within our region for several years now,” stated ITROM Pharmaceutical Group’s Managing Director Dr. Ismail Soboh. “We believe that Omidria definitely falls in this highly-sought-after category of products.”

About OMIDRIA^®

Omeros’ OMIDRIA^® (phenylephrine and ketorolac injection) 1% / 0.3% is the only FDA-approved product for use during cataract surgery or intraocular lens replacement to maintain pupil size by preventing intraoperative miosis (pupil constriction) and to reduce postoperative ocular pain. OMIDRIA also is the only NSAID-containing product FDA-approved for intraocular use. In post-launch studies across conventional and femtosecond laser-assisted cataract surgery, OMIDRIA has been shown (1) to be effective in patients with intraoperative floppy iris syndrome (IFIS), pseudoexfoliation and other ophthalmic conditions, (2) to significantly reduce complication rates, use of pupil-expanding devices and surgical times, and (3) to significantly improve uncorrected visual acuity on the first day following cataract surgery. While OMIDRIA is broadly indicated for use in cataract surgery in adults, the above outcomes are not in its currently approved labeling. Surgical time was not an endpoint in the OMIDRIA Phase 3 clinical trials and did not reach statistical significance in post hoc analysis of the Phase 3 data.

Important Risk Information for OMIDRIA^®

Systemic exposure of phenylephrine may cause elevations in blood pressure. In clinical trials, the most common reported ocular adverse reactions at two to 24 percent are eye irritation, posterior capsule opacification, increased intraocular pressure, and anterior chamber inflammation; incidence of adverse events was similar between placebo-treated and OMIDRIA-treated patients. OMIDRIA must be added to irrigation solution prior to intraocular use. OMIDRIA is not approved for use in children.
