LianBio Partner Tarsus Pharmaceuticals Announces U.S. FDA Approval of XDEMVY™ (lotilaner ophthalmic solution) 0.25% for the Treatment of Demodex Blepharitis
SHANGHAI, China and PRINCETON, N.J., July 26, 2023 (GLOBE NEWSWIRE) -- LianBio’s (Nasdaq: LIAN) partner, Tarsus Pharmaceuticals (Tarsus), announced yesterday that the U.S. Food and Drug Administration (FDA) approved XDEMVY™ (lotlilaner ophthalmic solution) 0.25% for the treatment of Demodex blepharitis. XDEMVY, formerly known as TP-03, is the first and only FDA approved treatment to directly target Demodex mites, the root cause of Demodex blepharitis.
LianBio in-licensed rights from Tarsus for the development and commercialization of TP-03 for Demodex blepharitis and Meibomian Gland Disease in Mainland China, Hong Kong, Macau and Taiwan. LianBio is currently conducting the LIBRA trial, a Phase 3 multicenter, double-blind, randomized, vehicle-controlled registrational study designed to evaluate the efficacy and safety of TP-03 in Chinese adult patients with Demodex blepharitis, with an open-label pharmacokinetics sub-study. LIBRA completed enrollment of 163 patients in June 2023. The co-primary endpoints are complete collarette cure (collarette score of 0) and mite eradication (mite density of 0 mites per lash) at day 43. Secondary endpoints include composite cure of collarette and erythema (collarette score of 0 and erythema score of 0) at day 43. LianBio expects to report topline results from LIBRA in the fourth quarter of 2023. More information about the LIBRA trial can be found on http://www.chinadrugtrials.org.cn/index.html (CTR20220726) and http://www.clinicaltrials.gov (NCT05629390).
"We congratulate Tarsus on receiving U.S. FDA approval of XDEMVY for the treatment of Demodex blepharitis,” said Yizhe Wang, Ph.D., Chief Executive Officer of LianBio. “XDEMVY is the only approved drug in the United States that targets the root cause of Demodex blepharitis, a disease that impacts an estimated 43 million patients in China. We look forward to concluding our LIBRA study this year, and if the data are positive, submitting a New Drug Application to support regulatory approval in China.”
About Demodex Blepharitis
Blepharitis is a common lid margin disease that is characterized by eyelid margin inflammation, redness and ocular irritation which not only causes ocular discomfort but can have an adverse effect on quality of life. Demodex blepharitis is caused by an infestation of Demodex mites, the most common ectoparasite found on humans which accounts for over two-thirds of all blepharitis cases. Demodex blepharitis may affect as many as 40 million people in China.
XDEMVY (lotilaner ophthalmic solution) 0.25%, formerly known as TP-03, is a novel prescription eye drop designed to treat Demodex blepharitis by targeting and eradicating the root cause of the disease – Demodex mite infestation. The active ingredient in XDEMVY is lotilaner, which is a well-characterized agent that eradicates Demodex mites by selectively inhibiting the mite’s GABA-Cl channels. It is a highly lipophilic molecule, which may promote its uptake in the oily sebum of the eye lash follicles where the mites reside. XDEMVY was evaluated in two pivotal trials conducted by Tarsus Pharmaceuticals in the United States collectively involving more than 800 patients. Both trials met the primary endpoint and all secondary endpoints, with statistical significance and no serious treatment-related adverse events. Most patients found the XDEMVY eye drop to be neutral to very comfortable. The most common ocular adverse reactions observed in the studies were instillation site stinging and burning which was reported in 10% of patients. Other ocular adverse reactions reported by less than 2% of patients were chalazion/hordeolum (stye) and punctate keratitis.
