Lyra will present data from its PK study of LYR-210 at the American Rhinologic Society's upcoming annual meeting in October 2021.
FREMONT, CA: Lyra Therapeutics, Inc., a clinical-stage pharmaceutical company that uses its proprietary XTreo" platform to deliver medications precisely, sustainably, and locally to the ear, nose, and throat (ENT) passages and other diseased tissues, declares positive topline results from the company's pharmacokinetic (PK) study of LYR-210. The study's findings support LYR-210's safety profile and provide a pharmacokinetic (PK) bridge to the established safety of mometasone furoate (MF) for a 505(b)(2) New Drug Application (NDA) submission.

The clinical trial is a 56-day open-label, multi-centre study in the United States of America to evaluate the pharmacokinetics and safety of LYR-210 in adult subjects with chronic rhinosinusitis (CRS). The study's primary objective is to characterize the pharmacokinetics of LYR-210. Twenty-four patients were enrolled in the study, with half receiving LYR-210 2500 g and the other half receiving LYR-210 7500 g. Both doses are found to be safe and well-tolerated, with the mean maximum plasma concentration (Cmax) observed with the 7500 ug dose being significantly less than the Cmax established for MF formulations approved by the US Food and Drug Administration. In addition, the MF blood plasma levels observed during the PK study are consistent with LYR-210's ability to deliver a consistent and steady dose throughout the treatment period. This is the first study of LYR-210 in the United States, and it is fully enrolled in 11 weeks across four sites.
"The data from our PK study suggests that LYR-210 can elute mometasone furoate safely, consistently for 6 months, and locally to the inflamed mucosal tissue of CRS patients," says Maria Palasis, Ph.D., President and Chief Executive Officer of Lyra Therapeutics. "These results will support a 505(b)(2) pathway for LYR-210s NDA submission. We are delighted at the rapid pace of enrollment of our first US patients and believe this bodes well for interest at US sites for our Phase 3 program, which we expect to initiate around the end of the year."
LYR-210 is highly convenient to implant and explant in a routine office visit and seamlessly conforms to the patient nasal anatomy, which enables continuous treatment for up to six months with one application,” says Randall Ow, MD, FACS, FARS, FAAOA, FAPCR, of Sacramento Ear Nose & Throat, and an investigator in the PK study. “LYR-210 has the potential to address a broad patient population and could provide a meaningful treatment option to CRS patients who fail medical management.”
