New subject matter listed in the U.S. Food and Drug Administration’s (“FDA”) Orange Book
HALIFAX, Nova Scotia, April 28, 2025 (GLOBE NEWSWIRE) -- Appili Therapeutics Inc. (TSX: APLI; OTCPink: APLIF) (the “Company” or "Appili "), a biopharmaceutical company focused on drug development for infectious diseases and medical countermeasures, today announced the United States Patent and Trademark Office and the Mexican Patent Office have granted new patent claims protecting its oral formulation of metronidazole, LIKMEZ®™.
The newly granted patents include:
- U.S. patent no. 20230086660A1 - Oral Formulations of Metronidazole and Methods of Treating an Infection Using Same
- Mexican patent no. 2020007494 - Oral Formulations of Metronidazole and Methods of Treating an Infection Using Same
The two new patents, set to expire in 2039 provide comprehensive protection for LIKMEZ, covering its unique taste masked composition and accessible therapeutic applications. Our partner, Saptalis Pharmaceuticals, LLC, has successfully undertaken the necessary steps to have the U.S. patent listed in the FDA Approved Drug Products with Therapeutic Equivalence Evaluations (Orange Book).
"Our proprietary formulation of metronidazole offers improved stability and palatability - key factors in helping patients adhere to their medications and improve treatment outcomes, " said Dr. Don Cilla, President and Chief Executive Officer at Appili Therapeutics. "Securing additional patents, shortly after launching LIKMEZ in the U.S., is a significant achievement that demonstrates the creativity of Appili’s R&D team, and reinforces our commitment to developing products for the benefit of patients and shareholders. "
“We are pleased with the issuance of the new patent for LIKMEZ,” said Polireddy Dondeti, Ph.D., President and Chief Executive Officer at Saptalis. “The listing of the patent in the Orange Book will ensure additional protection of the unique taste masking technology used in LIKMEZ formulation and support Saptalis’ team product commercialization activities. The timing of the listing is especially beneficial, as Saptalis is planning to re-launch LIKMEZ in May of this year under its own label.”
