OMEROS REPORTS SECOND QUARTER 2010 FINANCIAL RESULTS
Seattle, WA August 10, 2010 Omeros Corporation (NASDAQ: OMER), a biopharmaceutical company
committed to discovering, developing and commercializing products focused on inflammation and
disorders of the central nervous system, today announced financial results for the three and six
months ended June 30, 2010.
Total operating expenses for the three and six months ended June 30, 2010 were $8.1 million and
$14.9 million, respectively, compared to $6.1 and $11.5 million for the same periods in 2009. The
increases in operating expenses were primarily due to higher contract service and consulting costs
associated with several of the Company s clinical and preclinical programs as well as increased
costs associated with being a public company. In addition, the increases included a one-time
payment of $500,000 to Affitech AS in the first quarter of 2010 and a
one-time payment of $500,000
to Helion Biotech ApS in the second quarter of 2010 related to the Company s MASP-2 program.
For the three and six months ended June 30, 2010, Omeros reported a net loss of $7.8 million, or
$0.36 per share, and $14.5 million, or $0.68 per share, respectively. This is compared to a net
loss of $6.1 million, or $2.09 per share, and $11.6 million, or $3.96 per share, for the same
periods in 2009. At June 30, 2010, Omeros had cash, cash equivalents and short-term investments of
We made significant progress during the second quarter across many of our programs perhaps most
notably the successful identification of molecules that interact with, and modulate the signaling
of, three orphan GPCRs linked to cancer, metabolic disorders and appetite control, said Gregory A.
Demopulos, M.D., chairman and chief executive officer of Omeros. We expect that the second half
of 2010 will be equally productive as we prepare for data from at least two of our five clinical
programs currently underway, including our Phase 3 clinical trials evaluating OMS103HP in patients
undergoing arthroscopic ACL reconstruction and our Phase 1/Phase 2 trial of OMS201 in
Second Quarter and Recent Highlights
Secured a committed equity financing facility under which Omeros may, at its sole discretion, sell up to $40 million of its shares of common stock to Azimuth Opportunity, Ltd. over a 24-month period.
Enrolled the first patient in a Phase 2b, full-factorial clinical trial evaluating OMS302 in patients undergoing cataract surgery. OMS302, added to standard irrigation solution used during ophthalmological procedures, is the Company s proprietary PharmacoSurgery product in development to maintain mydriasis (pupil dilation) and reduce postoperative pain and inflammation following cataract and other lens replacement surgery.
Successfully unlocked three orphan G protein-coupled receptors (GPCRs) linked to cancer, metabolic disorders and appetite control.
Selected a clinical candidate for the Company s MASP-2 antibody program and initiated the cGMP manufacturing development process in preparation for clinical trials. MASP-2 appears to play a significant role in many inflammatory disorders including glomerulonephritis, macular degeneration, ischemia-reperfusion injury, transplant rejection and stroke.
Reported additional data from a Phase 2 trial of OMS103HP, Omeros lead PharmacoSurgery product candidate for arthroscopy, showing that patients treated with OMS103HP during arthroscopic partial meniscectomy surgery achieved statistically significant clinical benefits.
Entered into an Exclusive License Agreement with Helion Biotech ApS pursuant to which Omeros received a royalty-bearing, worldwide exclusive license in and to all of Helion s intellectual property rights related to MASP-2 antibodies, polypeptides and methods in the field of inhibition of mannan-binding lectin-mediated activation of the complement system for the prevention, treatment or diagnosis of any disease or condition. This agreement, together with the exclusive licenses of rights related to MASP-2 that Omeros already holds from the University of Leicester and the UK Medical Research Council, gives Omeros exclusive licenses to all ownership rights related to the patents and patent applications owned by these three organizations claiming antibodies that bind MASP-2, MASP-2 polypeptides, therapeutic methods and research tools, consolidating within Omeros the worldwide exclusive rights to the inhibition of MASP-2 and the antibodies targeting it.
