SEATTLE, May 10, 2011 /PRNewswire via COMTEX/ --

Omeros Corporation (NASDAQ: OMER), a biopharmaceutical company committed to discovering, developing and commercializing products focused on inflammation, coagulopathies and disorders of the central nervous system, today announced its financial results for the first quarter of 2011.

Financial Results

Total operating expenses for the three months ended March 31, 2011 were $7.7 million compared to $6.8 million for the same periods in 2010. The increase in operating expense was primarily due to increased clinical trial activities and additional employee costs. For the three months ended March 31, 2011, Omeros reported a net loss of $6.5 million, or $0.30 per share. During the same period in 2010, Omeros reported a net loss of $6.7 million, or $0.31 per share. At March 31, 2011, Omeros had cash, cash equivalents and short-term investments of $43.6 million.

"The first quarter included several significant events for Omeros, most notably the announcement that our OMS103HP Phase 3 ACL program did not meet its prespecified primary endpoints," said Gregory A. Demopulos, M.D., chairman and chief executive officer of Omeros. "While this setback delays OMS103HP's commercialization opportunity, the meniscectomy indication for the drug remains viable and, based on strong Phase 2 data, Phase 3 preparations are underway. We also recently reported positive results from our OMS302 Phase 2b, full-factorial OMS302 cataract trial and are submitting a request to the FDA for an end-of-Phase-2 meeting. We are evaluating our multiple options and will soon finalize our clinical plans for the remainder of 2011."

Recent Highlights

• Announced that Omeros obtained an exclusive license to novel antifibrinolytic agents for the control of surgical and traumatic bleeding. Research on these agents was published in the February 11, 2011 issue of the Journal of Biological Chemistry.
• Expanded its exclusive license to phosphodiesterase 7 (PDE7) inhibitors from Daiichi Sankyo Co., Ltd. to include the fields of addiction and compulsive disorders. Currently, Omeros is advancing PDE7 inhibitors for the treatment of these as well as movement disorders. Omeros is collaborating on this program with both the National Institute on Drug Abuse and The Michael J. Fox Foundation.
• Announced the identification of compounds that interact selectively with two orphan GPCRs linked to pancreatic cancer (GPR182) and cognitive disorders (GPR12). Together with the three previously unlocked orphans linked to squamous cell carcinoma (GPR87), obesity (GPR85) and appetite control (GPR101), Omeros has now publicly announced that it has successfully unlocked five orphan GPCRs for drug development.
• Reported positive results from the Phase 2b clinical trial evaluating OMS302 in patients undergoing cataract surgery. In this 221-patient study, subjects treated with OMS302 demonstrated statistically significant (p<0.0001) and clinically meaningful maintenance of mydriasis throughout the cataract procedure, and OMS302 significantly decreased (p=0.0418) pain in the early postoperative period and reduced the frequency of complaints of moderate and severe pain (2.5 times more complaints in the vehicle-treated patients). The product candidate was safe and well tolerated in this study.
• Announced that OMS103HP failed to meet prespecified efficacy endpoints in a Phase 3 clinical program in patients undergoing arthroscopic anterior cruciate ligament reconstruction surgery. The data were confounded, and Omeros could not determine whether a drug effect was present in these trials.
