SAINT LAURENT, Quebec, Sept. 19, 2023 (GLOBE NEWSWIRE) -- IntelGenx Corp. (TSX:IGX)(OTCQB:IGXT) (the "Company" or "IntelGenx") today provided a regulatory update on Buprenorphine Buccal Film, for which an abbreviated new drug application (“ANDA”) has been filed with the U.S. Food and Drug Administration (“FDA” or the “Agency”) by its co-developer, Chemo Research SL, through its agent and affiliate, Xiromed LLC (“Xiromed”).

As previously announced, Xiromed received a Complete Response Letter (“CRL”) from the FDA in April 2023. In response to the CRL, Xiromed submitted to the FDA an Amendment to the ANDA, requesting priority review. In an Amendment Acknowledgement received from the FDA by Xiromed, the FDA granted priority review with a Generic Drug User Fee Act (“GDUFA”) goal date for review of the Amendment of March 8, 2024, unless the Agency determines that an inspection is required. Alternatively, if the FDA determines that an inspection is required, the GDUFA goal date is July 8, 2024.

“We are pleased with our partner Xiromed’s prompt and fulsome response to the CRL, and are looking forward to the Agency’s decision,” commented Dwight Gorham, IntelGenx’s CEO. “Given the recent pre-approval inspection in March 2023 and subsequent approval of our Rizatriptan oral film, we are optimistic that the FDA will decide to review this Amendment without the need for an additional inspection of our facility.”
