SEATTLE, May 10, 2013 /PRNewswire/ -- Omeros Corporation (NASDAQ: OMER), a clinical-stage biopharmaceutical company committed to discovering, developing and commercializing products targeting inflammation, coagulopathies and disorders of the central nervous system, today announced its financial results for the first quarter of 2013.

Financial Results

Total operating expenses for the quarter ended March 31, 2013 were $11.1 million compared to $9.6 million for the same period in 2012. The increase is primarily due to research and development expenses associated with advancing Omeros' MASP-2 program toward the clinic, employee costs and non-cash rent expense, and to selling, general and administrative expenses related to legal matters and Omeros' planned commercial launch of OMS302 in 2014.  These higher costs were partially offset by lower clinical trial expenses related to the completion of Phase 3 clinical trials for Omeros' OMS302 and OMS103HP programs in January 2013 and December 2012, respectively.  For the quarter ended March 31, 2013, Omeros reported a net loss of $10.5 million, or $0.40 per share, compared to a net loss of $8.9 million, or $0.40 per share, for the same period in 2012.

At March 31, 2013, Omeros had cash, cash equivalents and short-term investments of $13.3 million. On May 9, Omeros announced that it priced a public offering of 3,903,004 shares of its common stock at a price of $4.14 per share, a two percent premium over the closing price on May 8, 2013, for estimated net proceeds of $16.1 million. The offering is expected to close on or about May 14, 2013. The shares were offered and are expected to be sold to RA Capital Management and other investors in a registered direct offering conducted without an underwriter or placement agent. Omeros also did not use its at-the-market sales facility or its committed equity line financing facility, neither of which Omeros has accessed to date.

"We are pleased with the progress across our pipeline during the first quarter, including successfully completing both our OMS302 intraocular lens replacement Phase 3 clinical program and the multiple ascending dose study for our OMS824 program," said Gregory A. Demopulos, M.D., chairman and chief executive officer of Omeros. "Looking ahead, we expect to submit the NDA for OMS302 this quarter, which will set the stage for a potential commercial launch in 2014.  Our MASP-2 and PDE7 programs are also slated for the clinic this year. There are multiple near-term milestones on the horizon, and 2013 promises to be an exciting year."

First Quarter Highlights

• Announced the successful completion of the multiple-ascending-dose (MAD) portion of its Phase 1 clinical study evaluating OMS824, the lead compound in Omeros' phosphodiesterase 10 (PDE10) program. OMS824 inhibits PDE10 and is being developed for the treatment of cognitive disorders, including Huntington's disease and schizophrenia. The results of the MAD study and earlier single-ascending dose study showed that the pharmacokinetic parameters (Cmax and AUC) of OMS824 increased linearly with the dose and that the compound had a long half-life consistent with once daily dosing. OMS824 was detected in the cerebrospinal fluid at the expected concentration relative to that in the blood. The drug concentration in the cerebrospinal fluid is predicted to achieve near-complete inhibition of the PDE10 target in the brain. These results show that OMS824, at well-tolerated doses, achieves concentrations that are anticipated to effectively inhibit PDE10 and support continuing development.
• Reported data from toxicology studies evaluating OMS721, the lead human monoclonal antibody in Omeros' mannan-binding lectin-associated serine protease-2 (MASP-2) program. The studies provide the primary safety data expected to support the initiation of OMS721 clinical studies in mid-year 2013. The pharmacokinetic results in primates demonstrated that subcutaneous administration of OMS721 resulted in maximal inhibition of the lectin pathway within six hours of administration and maintained it for two or more weeks. In addition, the bioavailability and pharmacokinetics observed in both species are expected to support subcutaneous administration in patients at a frequency of once weekly, bi-monthly or possibly at even longer intervals.
• Announced the successful completion of the 90-day safety database lock in the second of Omeros' two pivotal Phase 3 clinical trials evaluating OMS302 in patients undergoing intraocular lens replacement surgery. OMS302, added to standard irrigation solution used during ophthalmological procedures, is Omeros' proprietary PharmacoSurgery™ product designed to maintain intraoperative mydriasis and reduce postoperative pain and irritation resulting from cataract and other lens replacement surgery. Omeros intends to submit a New Drug Application for OMS302 to the U.S. Food and Drug Administration this quarter and a Marketing Authorization Application to the European Medicines Agency in mid-2013.
• Reported that its proprietary Cellular Redistribution Assay technology, which to date has successfully "unlocked" 46 of the 80 total Class A orphan G protein-coupled receptors (GPCRs) for drug development, has identified small molecules that interact with a Class B GPCR. Like the Class A GPCRs, Class B receptors are important players in a broad range of disorders, having been linked to various types of cancer (e.g., breast, brain, prostate, kidney, liver, pancreatic and gastrointestinal); multiple sclerosis, attention deficit-hyperactivity, learning and memory impairments, depression and other neuropsychiatric disorders; multiple metabolic disorders including diabetes and obesity; immunologic disorders; osteoporosis and infertility.
