About Acer Therapeutics
Acer, headquartered in Newton, MA, is a pharmaceutical company focused on the acquisition, development and commercialization of therapies for patients with serious rare and ultra-rare diseases with critical unmet medical need. Acer’s late-stage clinical pipeline includes two candidates for severe genetic disorders for which there are few or no FDA-approved treatments: EDSIVO™ (celiprolol) for vEDS, and ACER-001 (a fully taste-masked, immediate release formulation of sodium phenylbutyrate) for urea cycle disorders (UCD) and Maple Syrup Urine Disease (MSUD). There are no FDA-approved drugs for vEDS and MSUD and limited options for UCD, which collectively impact more than 4,000 patients in the United States. Acer’s product candidates have clinical proof-of-concept and mechanistic differentiation, and Acer intends to seek approval for them in the U.S. by using the regulatory pathway established under section 505(b)(2) of the Federal Food, Drug, and Cosmetic Act, or FFDCA, that allows an applicant to rely for approval at least in part on third-party data, which is expected to expedite the preparation, submission, and potential approval of a marketing application.
