SAN DIEGO, February 19, 2019 —Pfenex Inc. (NYSE American: PFNX) today announced that the U.S. Food and Drug Administration (FDA) has accepted for review the 505(b)(2) New Drug Application (NDA) for the Company’s lead product candidate, PF708, a Forteo® therapeutic equivalent in the treatment of osteoporosis, which achieved $1.6 billion in global product sales in 2018. The acceptance of the NDA indicates the application is sufficiently complete to permit a substantive review by the FDA. The FDA set a target goal date under the Prescription Drug User Fee Act (PDUFA) of October 7, 2019. Additionally, the Day-74 letter did not indicate that FDA is planning to hold an advisory committee meeting to discuss the NDA.
“The acceptance of the PF708 NDA filing is an important milestone for Pfenex as it brings us one step closer to the potential approval and U.S. commercial launch of PF708. We are pleased to achieve this stage in the U.S. regulatory pathway for PF708,” said Eef Schimmelpennink, Chief Executive Officer of Pfenex. “We believe PF708 remains on track to enter the U.S. market as early as the fourth quarter of 2019, subject to FDA approval and other factors.”
PF708 is being developed as a therapeutic equivalent candidate to Forteo®, which is approved and marketed by Eli Lilly and Company for the treatment of osteoporosis in certain patients with a high risk of fracture. Forteo achieved $1.6 billion in global product sales in 2018. PF708 is being developed pursuant to the 505(b)(2) regulatory pathway in the U.S. and references Forteo® as the Reference Listed Drug.
