The Company anticipates United States Food and Drug Administration (FDA) acceptance of the NDA within 30 days and a new assigned PDUFA date to be six months from the date of resubmission.

The NDA resubmission includes CMC data from a new third-party drug product manufacturing vendor. The new vendor’s facility was last inspected by the FDA in March 2024 and received "No Action Indicated" status, the highest FDA inspection classification indicating that a facility is in an acceptable state of current Good Manufacturing Practices (cGMP) compliance. The new vendor's CMC data package includes technical specifications similar to the original third-party manufacturing vendor, and the new vendor has already produced OLC drug product and completed 12-month stability studies. In addition, the Company has provided additional in-vitro bridging data between the two vendors as recommended by the FDA in previous discussions.

In June 2026, the Company received a Complete Response Letter (CRL) from the FDA regarding the first OLC NDA resubmission. The 2026 CRL cited the same third-party manufacturing deficiencies identified in a previous CRL issued in June 2025 to the initial NDA submission, as a result of the FDA not having conducted the reinspection of the original third-party manufacturing vendor. The FDA did not raise concerns regarding clinical efficacy or safety data and did not request additional data from the Company. The Company’s original third-party manufacturing vendor has received written notification from the FDA that its facility inspection has been assigned, but the inspection has not yet occurred as of September 29, 2026. If the original third-party manufacturing vendor is inspected in the near term and deemed cGMP-compliant, the Company plans to seek FDA alignment on a shorter approval timeline for the OLC NDA resubmission. Unicycive intends to keep both drug product vendors to maintain supply chain redundancy.
