FDA Facing Backlog of ODE Determinations: Attorneys
With FDA remaining silent on orphan drug exclusivities for products approved after the 2021 11th Circuit Court of Appeals decision in Catalyst Pharmaceuticals v. Becerra, there is a backlog of exclusivity decisions awaiting FDA action. That’s the report of attorneys Jacqueline Berman and Nikita Bhojani (Morgan Lewis) writing in an online blog post.
In a 1/24 notice to clarify drug exclusivity, FDA said it will continue to apply its orphan drug regulations so that exclusivity’s scope is tied to the specific orphan indication for which a drug is approved and not the indication for which the drug was designated.
The attorneys say it is unclear whether the agency intends to go back to address the gap in exclusivity determinations or whether it will only make determinations on an as-needed basis such as when a second product sponsor submits a marketing application.
“Sponsors who either have received approvals without exclusivity determinations or sponsors who have a need for information regarding the scope of existing exclusivities may want to consider formally requesting a decision by FDA,” the authors suggest. “Given the split between FDA’s and the court’s interpretation of the Federal Food, Drug, and Cosmetic Act, absent congressional action, it is likely a company whose exclusivity is drawn more narrowly to the approved indication may challenge the decision.”
The attorneys say that companies may reconsider strategies for requesting designations, going with as broad a designation as can be substantiated in the event of another challenge and court decision adopting the rationale in Catalyst.
