—OMIDRIA meets all objective criteria established by CMS—

SEATTLE--(BUSINESS WIRE)--Oct. 1, 2020-- Omeros Corporation (Nasdaq: OMER) today provided an update on the status of reimbursement for its cataract surgery drug OMIDRIA^® (phenylephrine and ketorolac intraocular solution) 1%/0.3%. The two-year extension of pass-through status provided by Congress through the Consolidated Appropriations Act of 2018 for OMIDRIA expired today. Omeros is actively engaged in requesting from the Centers for Medicare and Medicaid Services (CMS) and the Department of Health and Human Services (HHS) confirmation of separate payment status for OMIDRIA in the ambulatory surgery center (ASC) setting for 4Q 2020.

Omeros has also submitted to CMS both a comment letter on the proposed Outpatient Prospective Payment System/ASC Rule for Calendar Year (CY) 2021 and a legal memorandum from the law firm Foley Hoag LLP, reiterating that CMS regulations require non-opioid drugs that meet the objective regulatory criteria specified by CMS, including OMIDRIA, to be paid separately when used in the ASC setting. Omeros and its advisors are confident that (1) CMS is required by law to apply its separate payment policy for non-opioid pain management surgical drugs to OMIDRIA for 4Q 2020 and for CY 2021 and (2) CMS will address this issue soon and no later than its CY 2021 Final Rule, which is expected to be released on or shortly after November 1.

CMS’ policy for separate payment applies to non-opioid pain management surgical drugs that are used in the ASC setting and that are policy-packaged under CMS’ Outpatient Prospective Payment System. Now that its pass-through status has expired, OMIDRIA meets each of the objective regulatory criteria established by CMS for separate payment in the ASC payment system both for the remainder of 2020 and for CY 2021 – CMS has confirmed in previous annual rules that OMIDRIA is a non-opioid pain management drug used in the ASC setting that is policy packaged as a drug that functions as a supply in a surgical procedure. For further details, please see the comment letters referenced above, which can be found on the investor relations section of Omeros’ website at www.investor.omeros.com under “featured reports” or, once posted by the government, at https://www.regulations.gov/docket?D=CMS-2020-0090.

CMS is the primary insurer for 40-45 percent of cataract surgery patients. The large majority of cataract surgery procedures are performed in ASCs. In addition to Omeros’ current request with CMS and HHS for confirmation of separate payment in the ASCs, the Non-Opioids Prevent Addiction In the Nation (NOPAIN) Act (H.R.5172 and S. 3067) is continuing to make progress through both chambers of Congress. The bill has strong and growing bipartisan support, currently with over 50 sponsors and co-sponsors in the House of Representatives and more than 20 in the Senate. If enacted, the bill would provide separate Medicare reimbursement for non-opioid treatments to manage pain, like OMIDRIA, in both ASCs and hospital outpatient departments, renewable every five years. In any event, Omeros will remain committed to physicians’ ability to select the best medical care for their patients and to providing access to OMIDRIA for all cataract surgery patients.

About OMIDRIA^®

Omeros’ OMIDRIA^® (phenylephrine and ketorolac intraocular solution) 1% / 0.3% is the first and only FDA-approved product of its kind and is marketed in the U.S. for use during cataract surgery or intraocular lens replacement to maintain pupil size by preventing intraoperative miosis (pupil constriction) and to reduce postoperative ocular pain. OMIDRIA also is the only NSAID-containing product FDA-approved for intraocular use. In post-launch studies across conventional and femtosecond laser-assisted cataract surgery, OMIDRIA has been shown to (1) prevent intraoperative floppy iris syndrome (IFIS) and iris prolapse, (2) significantly reduce complication rates (including sight-threatening cystoid macular edema and breakthrough iritis), use of pupil-expansion devices, and surgical times, (3) significantly reduce intraoperative use of the opioid fentanyl and postoperative prescription opioids, and (4) significantly improve uncorrected visual acuity on the first day following cataract surgery. While OMIDRIA is broadly indicated for use in cataract surgery, the post-launch outcomes cited above are not in its currently approved labeling.

Important Safety 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 percent or greater 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.
