Omeros Invited to Present on OMS824 Phase 2 Clinical Program at the Schizophrenia International Research Conference

SEATTLE, April 1, 2014 /PRNewswire/ -- Omeros Corporation (NASDAQ: OMER) today announced that the company was invited by the organizers of the 2014 Biennial Conference of the Schizophrenia International Research Society (SIRS) to make an oral presentation on OMS824, the company's phosphodiesterase 10 (PDE10) inhibitor in development for the treatment of schizophrenia and Huntington's disease. OMS824 selectively inhibits PDE10, an enzyme expressed in areas of the brain linked to a wide range of diseases that affect cognition. The SIRS Conference will take place in Florence, Italy April 5-9. The Omeros presentation is entitled "Early Clinical Results of the Phosphodiesterase 10 Inhibitor OMS643762 in Development for the Treatment of Schizophrenia and Huntington's Disease" and is scheduled for Sunday April 6 during the pharmaceutical pipeline session. OMS643762 is the reference name for OMS824 in the company's clinical development program.

The presentation at the SIRS Conference will summarize Phase 1 and early Phase 2 data from Omeros' OMS824 clinical program. Steve Whitaker, M.D., Omeros' vice president of clinical development and chief medical officer, will make the presentation. SIRS was founded in 2005 and is dedicated to exchanging information about the latest advances in schizophrenia research among scientists, clinicians, drug developers, and policy makers internationally. The April 5-9 SIRS Conference in Florence is the fourth biennial conference and focuses on development of new drugs and the status of cutting edge research in the field of schizophrenia. The third biennial SIRS Conference held in 2012 was attended by over 1600 researchers from 53 countries.

About Omeros' PDE10 Program
PDE10 is an enzyme that is expressed in areas of the brain linked to diseases that affect cognition and psychomotor functions, including Huntington's disease and schizophrenia. Huntington's disease is a hereditary neurodegenerative disorder that leads to movement, cognition, and behavioral abnormalities and premature death. Schizophrenia is a group of severe brain disorders characterized by an abnormal interpretation of reality, which can manifest as delusions, hallucinations, and/or disordered thinking and behavior. Cognitive dysfunction is responsible for substantial disability in both of these diseases and is not meaningfully improved by current medications. Omeros' proprietary compound OMS824, currently in Phase 2 clinical programs, inhibits PDE10 and is being developed for the treatment of cognitive disorders. In addition to potential benefits on cognition, OMS824 could also improve the motor and psychiatric abnormalities in Huntington's disease as well as the positive (e.g., hallucinations) and negative (e.g., flat affect) symptoms of schizophrenia. Omeros has been awarded Orphan Drug designation by the US FDA to evaluate OMS824 in Huntington's disease, and received Fast Track designation from the FDA for the development of OMS824 to treat cognitive impairment in Huntington's disease.
