Item 8.01 Other Events.
On September 29, 2022, Amylyx Pharmaceuticals, Inc. (the “Company”) announced that the U.S. Food and Drug Administration (FDA) has approved RELYVRIO™ (sodium phenylbutyrate and taurursodiol) for the treatment of adults with amyotrophic lateral sclerosis (ALS). RELYVRIO (previously known as AMX0035 in the U.S.) significantly slowed the loss of physical function in people living with ALS in a randomized, placebo-controlled clinical trial. RELYVRIO can be taken as a monotherapy or with existing approved treatments.
ALS is a relentlessly progressive and fatal neurodegenerative disorder caused by motor neuron death in the brain and spinal cord. Motor neuron loss in ALS leads to deteriorating muscle function, the inability to move and speak, respiratory paralysis and eventually, death. More than 90% of people with ALS have sporadic disease, showing no clear family history. ALS affects approximately 29,000 people in the U.S.
The approval of RELYVRIO is based on data from CENTAUR, a multicenter Phase 2 clinical trial in 137 participants with ALS encompassing a 6-month randomized, placebo-controlled phase and an open-label extension (OLE) long-term follow-up phase. Detailed data from CENTAUR were published in the New England Journal of Medicine, Muscle & Nerve, and the Journal of Neurology, Neurosurgery, and Psychiatry.
The most common adverse events occurring with RELYVRIO (at least 15% and at least 5% greater than placebo) were diarrhea, abdominal pain, nausea, and upper respiratory tract infection. Gastrointestinal-related adverse reactions occurred throughout the study but were more frequent during the first three weeks of treatment.
A copy of the press release announcing the approval of RELYVRIO, attached as Exhibit 99.1 hereto, is being furnished and shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and is not incorporated by reference into any of the filings of the Company under the Securities Act of 1933, as amended or the Exchange Act, whether made before or after the date hereof, regardless of any general incorporation language in any such filing.
