FDA Rejects Apiject's NDA for Glycopyrrolate Combination Product
FDA has issued a Complete Response Letter (CRL) to Apiject Systems Corp., declining to approve the company's NDA for a glycopyrrolate solution drug-device combination product, seeking an indication for use in adults as adjunctive therapy for treating peptic ulcers by reducing the amount of acid produced.The application, which was originally submitted on Sept. 25, 2025, was deemed not approvable because of unresolved deficiencies related to the quality, performance and safety of the combination product, according to the 7/21 rejection letter.
The CRL is the latest posted by the agency after it recently restarted the transparency initiative (see story) while it prepares a proposed rule to cement such postings. Much of the FDA's discussion of the deficiencies is redacted, but the agency divided its concerns into several broad categories, including the drug constituent of the combination product, the device constituent's performance and safety, human factors, and manufacturing. The letter also notes that amendments submitted by the company in June were acknowledged but not reviewed as part of the agency's action and may be incorporated into a future response.
In addition to addressing the product deficiencies, FDA instructed Apiject to provide updated safety information if the application is resubmitted, including new clinical safety data, revised adverse event tabulations, analyses of trial discontinuations, case narratives for serious adverse events and deaths, updated patient exposure data, worldwide postmarketing safety experience, and current foreign labeling. The agency characterized other comments in the letter as recommendations rather than approvability issues.
