FDA approves LIKMEZ as the brand name for Metronidazole Oral Suspension (LIKMEZ is a Trademark of Saptalis Pharmaceuticals, LLC)

Currently LIKMEZ is the only liquid oral suspension of metronidazole approved in the U.S.

Patent coverage provides drug market exclusivity through at least 2039

Appili Therapeutics Inc. (TSX:APLI; OTCQB: APLIF) (the “Company” or “Appili”), a biopharmaceutical company focused on drug development for infectious diseases and biodefense, today announced that its manufacturing and commercialization partner, Saptalis Pharmaceuticals, LLC (“Saptalis”) received approval from the U.S. Food and Drug Administration ("FDA”) for Metronidazole Oral Suspension 500mg/5mL (ATI-1501). ATI-1501, Appili’s liquid oral reformulation of the antibiotic metronidazole, has been licensed to Saptalis for commercialization in the U.S., and other selected territories. The FDA also approved LIKMEZ™ as the brand name for ATI-1501.

“The FDA approval of LIKMEZ, shortly after securing patent coverage through 2039, is an important milestone that demonstrates Appili’s ability to identify promising opportunities and develop and monetize them for the benefit of both patients and shareholders,” said Don Cilla, Pharm.D., M.B.A., Appili’s President and CEO. “Difficulty swallowing tablets and capsules should not be a barrier to accessing appropriate antibiotic therapy. LIKMEZ provides a convenient alternative for patients who have difficulty taking solid oral medicines.” Dr. Cilla adds “Appili was formed to develop ATI-1501 and it is exciting to see our first development project make it to market. This is a tremendous team accomplishment. We are all delighted that the product will soon be available to patients and we look forward to bringing additional products to market that tackle serious global challenges in infectious disease.”

“We are pleased with the approval of the NDA for LIKMEZ,” said Polireddy Dondeti, Ph.D., President and CEO at Saptalis. “We are proud of our team which, using Appili’s taste masking technology, has successfully developed a commercial product approved by the FDA. LIKMEZ will address a clear market need in a more convenient dosage form of metronidazole, and we are prepared to initiate marketing and distribution activities in the very near future.”

Metronidazole is a widely used frontline oral treatment with over 10 million prescriptions written in the United States every year to help treat parasitic and anaerobic bacterial infections. The current tablet form of metronidazole is the only other approved oral form on the U.S. market, but its bitter taste and lack of appropriate dosage forms for patients with difficulty swallowing often presents treatment compliance challenges.

Appili expects to receive milestone payments and royalties from Saptalis based on this FDA approval and Saptalis’ commercialization plans.
