Disclosure of Omidria Post-Launch Study Findings to Occur at Hawaiian Eye and Retina Conference

SEATTLE--(BUSINESS WIRE)--Jan. 15, 2016-- Omeros Corporation (NASDAQ: OMER), a biopharmaceutical company committed to discovering, developing and commercializing small-molecule and protein therapeutics for both large-market as well as orphan indications targeting inflammation, coagulopathies and disorders of the central nervous system, today announced that Omidria® (phenylephrine and ketorolac injection) 1% / 0.3% will be the focus of a series of presentations and panel discussions by thought leaders in cataract surgery at Hawaiian Eye and Retina, an annual conference of over 1,200 ophthalmologists, retina specialists, nurses, allied health professionals and administrators. The first of these presentations and discussions will occur on Sunday, January 17, 2016, at which time certain information regarding Omidria will be made public. To ensure that developments regarding Omeros’ business are publicly disseminated to securities markets in consistent fashion, Omeros is announcing that the information to be presented at the conference includes a summary of investigator-sponsored studies, which have resulted in abstracts and manuscripts accepted, submitted or in preparation, reporting that the use of Omidria across a wide range of patients, including those with non-complex cataracts, complex cataracts, intraoperative floppy iris syndrome (IFIS) and/or pseudoexfoliation, has resulted in statistically significant:

  • reduction in complications associated with small pupils;
  • reduction in usage of pupil-expanding devices;
  • prevention of miosis during femtosecond laser-assisted surgery;
  • reduction in age-adjusted surgical times; and
  • improvement in best corrected visual acuity (BCVA) on the day after surgery.

The above outcomes are not referenced in the currently approved labeling for Omidria. Omidria is broadly indicated for use in cataract surgery in adult patients.

The above findings are from investigator-sponsored, case-controlled/cohort, single-center studies, ranging from approximately 50 to over 1,100 patients, and have not yet been published. Omeros’ earlier Phase 3 clinical trials evaluating Omidria were not powered to demonstrate statistical differences in surgical times and BCVA, and results from those Phase 3 trials did not reach statistical significance for those measurements. Complication rates and use of pupil-expanding devices were not assessed in the Phase 3 trials, and femtosecond laser cases were excluded for purposes of standardization given that not all investigators in the Omidria Phase 3 program used this equipment in cataract surgery. Consistent with publication guidelines, detailed data from these investigator-sponsored studies will be available in the published abstracts and journal articles.

About Omidria®

Omeros’ PharmacoSurgery® product Omidria® contains the mydriatic (pupil-dilating) agent phenylephrine and the anti-inflammatory agent ketorolac and was developed for use during cataract or other IOL replacement surgery. The FDA has approved Omidria for use during cataract surgery or IOL replacement to maintain pupil size by preventing intraoperative miosis (pupil constriction) and to reduce postoperative ocular pain.

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.

Derived from its proprietary PharmacoSurgery® platform, the company’s first drug product, Omidria® (phenylephrine and ketorolac injection) 1%/0.3%, has been approved by the FDA for use during cataract surgery or intraocular lens (IOL) replacement to maintain pupil size by preventing intraoperative miosis (pupil constriction) and to reduce postoperative ocular pain. In the European Union, the European Commission (EC) has approved Omidria for use in cataract surgery and lens replacement procedures to maintain mydriasis (pupil dilation), prevent miosis (pupil constriction), and to reduce postoperative eye pain. Omeros has five clinical-stage development programs focused on: complement-related thrombotic microangiopathies; Huntington’s disease, schizophrenia, and cognitive impairment; addictive and compulsive disorders; and preventing problems associated with urologic surgical procedures. In addition, Omeros has a proprietary GPCR platform, which is making available an unprecedented number of new GPCR drug targets and corresponding compounds to the pharmaceutical industry for drug development.
