Item 8.01     Other Events
On February 11, 2021, AcelRx Pharmaceuticals, Inc. (the “Company”) received a warning letter from the Office of Prescription Drug Promotion (“OPDP”) of the U.S. Food and Drug Administration (the “FDA”) (the “Letter”) relating to a banner advertisement the Company submitted to the OPDP on December 6, 2019 (the “Banner Ad”),  and a tabletop display the Company submitted on February 28, 2020, and resubmitted to the OPDP at its request on September 23, 2020 (the “Tabletop Display,” and together with the Banner Ad, the “Promotional Material”).  The Company submitted the materials to the OPDP pursuant to the FDA requirement that sponsors submit all promotional materials to the FDA at the time of their initial dissemination or publication. The FDA’s concerns identified in the Letter include its view that the Promotional Material makes misleading claims and representations about the risks and efficacy of DSUVIA® because the Promotional Material does not reveal facts that are material in light of the representations made.  The Company believes it can easily address these concerns without a material impact to the Company given the nature of the Promotional Materials and because the Company has not used the Banner Ad since late 2019, nor used the table drape that is part of the Tabletop Display since November 2019; however, the Company plans to review its marketing materials to identify any potential revisions in light of the Letter.  The Company intends to respond to the FDA within the timeframe requested in the Letter and seek guidance and clarification from the FDA on the concerns raised in the Letter. The Letter does not restrict the Company’s ability to manufacture or sell DSUVIA.  The Company cannot give any assurances, however, that the FDA will be satisfied with its response to the Letter or that such response will resolve the issues identified in the Letter.
Forward-Looking Statements
This Current Report on Form 8-K contains forward-looking statements, including, but not limited to, statements related to the Company’s intent to respond to the Letter in the timeframe required by the FDA and the Company’s belief that the concerns set forth in the Letter can be resolved without a material impact to the Company or its financial statements.
