Sandoz Amends ANDA to Not Seek Approval for Generic Version of OMIDRIA Until Patents for Omeros' Drug Expire


-- With Voluntary Dismissal of Infringement Suit Against Sandoz,
Omeros Wraps Up All Pending ANDA Litigation --

Omeros Corporation (NASDAQ:OMER) today announced that its patent
infringement lawsuit against Sandoz Inc. (Sandoz) concerning Sandoz's
Abbreviated New Drug Application (ANDA), which sought approval from the
U.S. Food and Drug Administration (FDA) to market a generic version of
Omeros' cataract surgery drug OMIDRIA® (phenylephrine and
ketorolac intraocular solution) 1% / 0.3%, has been dismissed by
stipulation of the parties. Omeros agreed to the dismissal because
Sandoz amended its ANDA to no longer seek FDA approval to market its
proposed generic drug prior to the expiration of all of Omeros' Orange
Book-listed patents for OMIDRIA. The latest expiry date of these patents
is July 2033.

Omeros commercially launched OMIDRIA, the only FDA-approved product of
its kind, in 2015. Two years later, in the setting of steadily
increasing OMIDRIA sales, Omeros received a Paragraph IV certification
from Sandoz in connection with Sandoz's ANDA filing for a generic
version of OMIDRIA. Omeros responded with patent infringement litigation
against Sandoz. Sandoz has now converted to a Paragraph III
certification, which means that FDA cannot approve the ANDA until after
the July 2033 expiry of all patents listed in the Orange Book for
OMIDRIA, namely U.S. Patent No. 8,173,707, U.S. Patent No. 8,586,633,
U.S. Patent No. 9,066,856, U.S. Patent No. 9,278,101, U.S. Patent No.
9,399,040, U.S. Patent No. 9,486,406, and U.S. Patent No. 9,855,246.

With Sandoz' conversion to a Paragraph III certification and Omeros'
agreement to dismiss its patent infringement litigation against Sandoz,
all of Omeros' pending litigation with ANDA filers has been concluded.
Omeros previously announced that it had settled lawsuits against two
other ANDA filers – Par Sterile Products, LLC and Par Pharmaceutical,
Inc. (Par) and Lupin Ltd. and its subsidiary Lupin Pharmaceuticals, Inc.
(Lupin). Based on these settlement agreements, the earliest ANDA entry
date for any of the three generic manufacturers is April 2032 unless
otherwise subsequently authorized pursuant to the settlement agreements.

"We are pleased that Par, Lupin and now Sandoz have decided to respect
our OMIDRIA patents," stated Gregory A. Demopulos M.D., chairman and
chief executive officer of Omeros. "With the favorable resolution of all
three generic challenges, Omeros now is planning for nearly 14 years of
market exclusivity for OMIDRIA. We look forward to the October 1
re-initiation of CMS' pass-through status and separate payment for
OMIDRIA so that, once again, we can ensure broad access to the drug's
benefits for ophthalmic surgeons and their cataract surgery patients."
