How could BDR's lawsuit challenging FDA drug exclusivity affect CDER?
BDR's lawsuit may force CDER to accelerate generic drug approvals BDR Pharmaceuticals filed a lawsuit against the FDA, challenging the agency's recognition of 10 years of New Chemical Entity (NCE) exclusivity for Phathom Pharmaceuticals' drug, VOQUEZNA. This exclusivity was granted through May 3, 2032. The lawsuit alleges the FDA improperly applied the GAIN Act. If BDR succeeds in its challenge, the regulatory exclusivity period for VOQUEZNA could be reduced, which would permit the FDA to receive and potentially approve Abbreviated New Drug Applications (ANDAs) referencing VOQUEZNA tablets earlier than currently anticipated, thereby altering CDER's review timeline for generic competition.

BDR Pharmaceuticals filed a lawsuit against the U.S. Food and Drug Administration and related Federal Defendants in the United States District Court for the District of Columbia. The suit primarily challenges the FDA's refusal to accept an abbreviated new drug application (ANDA) referencing Phathom Pharmaceuticals' new drug application (NDA) for VOQUEZNA®. BDR alleges that the FDA improperly used the GAIN Act to extend Phathom's New Chemical Entity (NCE) exclusivity for VOQUEZNA tablets. Phathom Pharmaceuticals stated that the FDA correctly evaluated this matter in its June 6, 2025 grant of Phathom’s December 11, 2024 Citizen Petition, which granted 10 years of NCE exclusivity for VOQUEZNA tablets through May 3, 2032.
The full event1independent outlet -
BDR Pharmaceuticals filed suit against the FDA, principally challenging the agency's decision to grant Phathom Pharmaceuticals 10 years of NCE exclusivity for VOQUEZNA tablets through May 3, 2032. The suit alleges the FDA improperly applied the GAIN Act in this process. The Center for Drug Evaluation and Research (CDER) is the division of the FDA responsible for evaluating drug applications, including New Drug Applications (NDAs) and Abbreviated New Drug Applications (ANDAs), which determine market access and exclusivity periods. If BDR succeeds in its challenge, the regulatory exclusivity period for VOQUEZNA could be reduced. This would permit the FDA to receive and potentially approve ANDAs referencing VOQUEZNA tablets earlier than currently anticipated, requiring CDER to adjust its review schedule.

Why it matters
The stakes revolve around market exclusivity and competition. Phathom Pharmaceuticals relies on the recognized 10-year NCE exclusivity for VOQUEZNA to maintain its market position and revenue stream. If BDR succeeds, this exclusivity could be reduced, opening the door for generic competition sooner than planned.
This litigation highlights the ongoing tension between pharmaceutical companies seeking maximum market protection and generic manufacturers challenging regulatory decisions. The outcome of this specific challenge could set a precedent for how the FDA manages exclusivity periods for other drugs under the GAIN Act.
