INVESTIGATION NOTICE: The Schall Law Firm Announces it is Investigating Claims Against Omeros Corporation and Encourages Investors with Losses to Contact the Firm

LOS ANGELES, Oct. 7, 2021

The investigation focuses on whether the Company issued false and/or misleading statements and/or failed to disclose information pertinent to investors. Omeros announced on October 1, 2021, that the FDA found deficiencies with its Biologics License Application for its drug candidate narsoplimab. The FDA wrote that these deficiencies "preclude discussion of labeling and post-marketing requirements/commitments at this time." The Company also disclosed that the "FDA did not provide specific details of the deficiencies in its notification," and that "the company does not currently expect any resolution to occur by the October 17, 2021 target action date under the Prescription Drug User Fee Act (PDUFA)." Based on this news, shares of Omeros fell by more than 38% on the same day.
