SAINT LAURENT, Quebec, June 11, 2020 (GLOBE NEWSWIRE) -- Saint Laurent, Quebec, June 11, 2020 – IntelGenx Corp. (TSX V:IGX)(OTCQB:IGXT) (the "Company" or "IntelGenx") today provided an update regarding its RIZAPORT® VersaFilm® program following its Type A meeting with the U.S. Food & Drug Administration ("FDA") that took place on June 10, 2020.

On March 27, 2020, IntelGenx received a Complete Response Letter (“CRL”) from the FDA regarding its resubmitted 505(b)(2) New Drug Application (“NDA”) for RIZAPORT® VersaFilm® for the treatment of acute migraines. The CRL states that the FDA cannot approve the application in its present form. The Agency requested additional information, but no new bioequivalence study.

At the meeting, IntelGenx obtained clarity from the Agency on the Chemistry, Manufacturing and Controls (CMC) information required for resubmission of the NDA.

“The Type A meeting with the FDA was very productive and we are pleased with the outcome,” said Dr. Horst G. Zerbe, CEO of IntelGenx. “We are looking forward to completing the work required to resubmit our RIZAPORT® VersaFilm® NDA and remain committed to making this innovative new oral film product available to people suffering from migraines. We look forward to providing further updates on our progress as developments unfold.”
