• LIBRA trial designed to support registration in China
• Topline results expected in the fourth quarter of 2023
SHANGHAI and PRINCETON, N.J., Nov. 01, 2022 (GLOBE NEWSWIRE) -- LianBio (Nasdaq: LIAN), a biotechnology company dedicated to bringing innovative medicines to patients in China and other major Asian markets, today announced the first patient has been dosed in the Phase 3 LIBRA clinical trial of TP-03 in Chinese patients with Demodex blepharitis.
“Although Demodex blepharitis is a highly prevalent eye disease, with an estimated 43 million patients in China alone, there are currently no available therapeutics approved by either the FDA or China National Medical Products Administration,” said Yizhe Wang, Ph.D., Chief Executive Officer of LianBio. “In U.S. clinical trials, TP-03 demonstrated statistically significant disease resolution and was safe and well tolerated. LianBio is committed to improving the standard of care for patients with Demodex blepharitis by rapidly bringing this first-in-class, innovative medicine to China. We are very pleased to be working with leading ophthalmology centers to conduct the LIBRA trial to support registration in our licensed territories.”
TP-03 is a novel investigational therapeutic designed to resolve the signs of Demodex blepharitis by targeting and eradicating the root cause of the disease – Demodex mite infestation. Lotilaner, the active ingredient in TP-03, is a well-characterized agent that eradicates Demodex mites by selectively inhibiting the GABA-Cl channels. In two pivotal Phase 3 studies of TP-03 conducted in the United States, TP-03 met all primary and secondary endpoints, effectively resolving Demodex blepharitis and was safe and well tolerated. LianBio in-licensed rights from Tarsus Pharmaceuticals, Inc., for the development and commercialization of TP-03 in Mainland China, Hong Kong, Macau and Taiwan.
LIBRA is a Phase 3 multicenter, double-blind, randomized, placebo-controlled registrational study designed to evaluate the safety and efficacy of TP-03 in Chinese patients with Demodex blepharitis. LIBRA is expected to enroll 162 patients. The co-primary endpoints are complete collarette cure (0-2 collarettes per eyelid) and mite eradication (mite density of 0 mites per lash) at day 43. Secondary endpoints include composite cure of collarette and erythema (0-2 collarettes per eyelid and grade 0 erythema) at day 43. More information about the LIBRA trial can be found on http://www.chinadrugtrials.org.cn/index.html (CTR20220726).
LianBio expects to report topline results from the LIBRA trial in the fourth quarter of 2023.
About Demodex Blepharitis
Blepharitis is a common ocular condition that is characterized by inflammation of the eyelid margin, redness and ocular irritation. Demodex blepharitis is caused by infestation of Demodex mites, the most common ectoparasite found on humans. Demodex mites cause approximately 45% of blepharitis. Currently, there are no treatments approved by the FDA or China National Medical Products Administration for Demodex blepharitis.
TP-03 (lotilaner ophthalmic solution, 0.25%) is a novel, investigational therapeutic designed to resolve the signs of Demodex blepharitis by targeting and eradicating the root cause of the disease – Demodex mite infestation. Lotilaner is a well-characterized agent that eradicates Demodex mites by selectively inhibiting the 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. TP-03 was evaluated in two pivotal trials 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. Both trials also demonstrated that TP-03 was well-tolerated. The most common adverse event occurring at a frequency of >2% in TP-03 treated patients was instillation site pain/burning/stinging. All adverse events were either mild or moderate. If approved, TP-03 may offer treatment for millions of patients with Demodex blepharitis. TP-03 is now also being studied for the treatment of Meibomian Gland Disease in patients with Demodex mites.
