Acer Therapeutics Inc. (NASDAQ:ACER) ("Acer") and its collaboration partner, RELIEF THERAPEUTICS Holding SA (OTC:RLFTF) ("Relief"), today announced that the U.S. Food and Drug Administration (FDA) has accepted for filing the New Drug Application (NDA) for ACER-001 (sodium phenylbutyrate) for the treatment of patients with Urea Cycle Disorders (UCDs). The FDA has assigned a Prescription Drug User Fee Act (PDUFA) target action date of June 5, 2022. Acer's 505(b)(2) NDA is supported by results from two previously announced bioequivalence (BE) trials in which ACER-001 showed similar relative bioavailability for both phenylbutyrate (PBA) and phenylacetate (PAA), the active metabolite of sodium phenylbutyrate, compared to the reference listed drug, BUPHENYL® (sodium phenylbutyrate). "With FDA commencing a substantive review of our NDA, ACER-001 is one step closer to potentially providing an alternative treatment option for patients with UCDs," said Chris Schelling, Chief Executive Officer and Founder of Acer. "We look forward to working with the FDA during their review of our application. In addition, we continue to collaborate with our partners to ensure we are well positioned to support a successful commercial launch of ACER-001, subject to FDA approval." Jack Weinstein, Chief Financial Officer and Treasurer of Relief, added, "Our collaboration with Acer is thriving and we are pleased with the progress they have made in advancing ACER-001. In parallel with Acer's activities, we continue to execute on our global commercial strategy for ACER-001 which includes our intended submission of a Marketing Authorization Application (MAA) for the treatment of patients with UCDs in Europe in Q2/Q3 2022."
