On July 7, 2023, Outset Medical disclosed in a filing with the U.S. Securities and Exchange Commission that “[o]n July 6, 2023, Outset Medical, Inc. (the ‘Company’) received a Warning Letter, dated July 5, 2023 (the ‘Warning Letter’), from the United States Food and Drug Administration (the ‘FDA’).” The filing stated that, as previously disclosed in the Company’s annual report, “the FDA issued an FDA Form-483 identifying four inspectional observations resulting from an FDA inspection that concluded on February 10, 2023” and that “[t]he Warning Letter raises two additional observations. The first observation asserts that certain materials reviewed by the FDA and found on the Company’s website promote continuous renal replacement therapy (CRRT), a modality outside of the current indications for the Tablo® Hemodialysis System. The Company believes this concern has been effectively addressed through labeling and promotional changes already underway. The second observation asserts that the TabloCart with Prefiltration (the ‘TabloCart’), requires prior 510(k) clearance for marketing authorization. . . . The Company intends to work collaboratively with the FDA to resolve this observation, including potentially submitting a 510(k) on TabloCart.”
