FDA Loses Court Case Over Generic Minocin
The Washington DC District Court has ruled against FDA in granting summary judgment to plaintiff Melinta Therapeutics that suspends the approval of a generic version of the company’s Minocin (minocycline), which treats bacterial infections, manufactured by Nexus Pharmaceuticals. In seeking FDA approval of its ANDA in 2020, a required Paragraph 4 was sent to Melinta via Fed Ex delivery, but it was never signed by a company representative acknowledging receipt of delivery, according to the court opinion.
The Fed Ex delivery notice shows that it was delivered 12/8/2020, but with no receipt signature by Melinta because the delivery service suspended its normal signature process due to Covid-19 restrictions. Melinta further claims that it did not actually receive the notice until 3/31/2021, after which it had 45 days to initiate a patent infringement suit against Nexus. FDA disagreed with Melinta’s argument and denied a related citizen petition that sought confirmation of the 3/31 delivery date, and it subsequently approved the Nexus ANDA.
The court says it agreed with Melinta that the term “signature proof of delivery,” as used in 21 CFR § 314.95(e), “unambiguously requires the signature of the recipient or a designated representative, and therefore that FDA is not entitled to deference in its interpretation that it does not.”
The court further ordered FDA’s approval of Nexus’s ANDA to be vacated and remanded the case to the agency for further action consistent with the opinion.
