Partnership opens expanded opportunity for LYR-210 to address chronic rhinosinusitis, a disease affecting approximately 88 million adults in China

Lyra Therapeutics, Inc. (Nasdaq: LYRA), a clinical-stage therapeutics company leveraging its proprietary XTreo™ platform to enable precise, sustained, and local delivery of medications to ear, nose and throat (ENT) passages and other diseased tissues, and LianBio, a biotechnology company dedicated to bringing paradigm-shifting medicines to patients in China and other major Asian markets, today announced a strategic partnership and exclusive license agreement for the development and commercialization of LYR-210 in Greater China (mainland China, Hong Kong, Taiwan, and Macau), South Korea, Singapore and Thailand. LYR-210 is an anti-inflammatory, intra-nasal drug matrix in late-stage development that is designed to treat chronic rhinosinusitis (CRS), a debilitating inflammatory disease of the nasal passages.

Under the terms of the agreement, Lyra will receive an upfront payment of $12 million and is eligible to receive up to $135 million in future payments based upon the achievement of specified development, regulatory and commercialization milestones. Upon commercialization on a region-by-region basis, Lyra also will be entitled to receive low double-digit royalties based on net sales of LYR-210 in the licensed territories. LianBio will be responsible for the clinical development and commercialization of LYR-210 in the licensed territories, and Lyra will retain all rights to LYR-210 in all other geographies. As part of the agreement, LianBio will also have the first right to obtain development and commercial rights in the licensed territories to Lyra’s LYR-220, an anti-inflammatory, intra-nasal, drug matrix in development for the treatment of CRS patients who have undergone a prior sinus surgery but continue to have persistent disease.

“We are delighted to enter into this strategic alliance with LianBio to expand the global reach of LYR-210 for millions of CRS patients who need new and innovative treatment alternatives to surgery,” said Maria Palasis, Ph.D., CEO of Lyra. “The LianBio team has deep expertise in drug development and is well positioned to successfully commercialize LYR-210 in these Asian territories. The introduction of our novel, integrated ENT drug and delivery solution to the large patient populations in Asian markets supports our planned global commercialization strategy.”

“CRS patients who have failed medical management are currently left with limited and invasive options to manage their disease,” said Yizhe Wang, Ph.D., Chief Executive Officer of LianBio. “In clinical studies conducted to date, LYR-210 has demonstrated six months of clinically meaningful symptom improvement following a single administration in patients with and without polyps. With an estimated 88 million adult CRS patients in China alone, we believe LYR-210 has the potential to address a significant unmet medical need and meaningfully improve the standard of care for patients in Asia.”
