Item 8.01

Other Events.

On October 17, 2023, Mirum Pharmaceuticals, Inc. (the “Company”) announced that the U.S. Food and Drug Administration (the “FDA”) has extended the review of the Supplemental New Drug Application (“sNDA”) for LIVMARLI^® (maralixibat) oral solution for the treatment of cholestatic pruritus in patients with progressive familial intrahepatic cholestasis (“PFIC”). The new Prescription Drug User Fee Act (“PDUFA”) date is March 13, 2024.

The FDA extended the PDUFA goal date to allow time for a full review of a submission provided in response to an FDA information request, which the FDA deemed a major amendment. The submission comprised further analysis of certain clinical information that was previously provided to the FDA by the Company. No additional data or studies have been requested.

Forward Looking Statements

This Current Report on Form 8-K contains “forward-looking statements” as that term is defined in the Private Securities Litigation Reform Act of 1995. Without limiting the foregoing, these statements are often identified by the words “look forward to”, “will,” “may”, “might”, “believes”, “anticipates”, “plans”, “expects”, “intends,” “potential” or similar expressions. In addition, expressions of strategies, intentions or plans are also forward-looking statements. Such forward-looking statements include, but are not limited to, references to: the updated PDUFA date for the PFIC sNDA and the timeline for the FDA’s review of Company-submitted data. Because such statements are subject to risks and uncertainties, actual results may differ materially from those expressed or implied by such forward-looking statements. Other factors that might cause such a difference include those discussed in the Company’s filings with the SEC. All forward-looking statements contained in this press release speak only as of the date on which they were made and are based on management’s assumptions and estimates as of such date. The Company undertakes no obligation to update such statements to reflect events that occur or circumstances that exist after the date on which they were made, except as required by law.
