Announcement
Phathom Pharmaceuticals, Inc announced today it has submitted a Citizen Petition (CP) with the U.S. Food and Drug Administration (FDA).
AI Summary
Phathom Pharmaceuticals announced today that it has submitted a Citizen Petition to the U.S. Food and Drug Administration (FDA). The petition requests that the FDA correct the Orange Book listings for VOQUEZNA (vonoprazan) tablets to reflect the full 10‐year New Chemical Entity (NCE) exclusivity period, which ends on May 3, 2032. Phathom argues that since VOQUEZNA tablets contain the same active ingredient as the VOQUEZNA TRIPLE PAK and DUAL PAK products—which were granted a 10-year exclusivity period under the GAIN Act—all vonoprazan-based products should benefit equally. The company believes that the current listings do not accurately show the full period of exclusivity as mandated by law. The FDA is expected to review the petition and respond within 180 days from submission.
