LianBio Partner Tarsus Pharmaceuticals Announces Positive Topline Data from Second Pivotal Trial of TP-03 for the Treatment of Demodex Blepharitis

LianBio Holds Development and Commercialization Rights to TP-03 in Greater China

SHANGHAI, China and PRINCETON, N.J., May 03, 2022 (GLOBE NEWSWIRE) -- LianBio’s (Nasdaq: LIAN) partner, Tarsus Pharmaceuticals, Inc. (Tarsus) yesterday announced that TP-03 (lotilaner ophthalmic solution, 0.25%) met the primary endpoint and all secondary endpoints in the Saturn-2 pivotal Phase 3 trial with a favorable safety profile, reinforcing its potential to resolve Demodex blepharitis, a highly prevalent eyelid disease. With these results, Tarsus plans to submit a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) in the second half of 2022.

“We congratulate our partner Tarsus on continuing to demonstrate clinically meaningful and statistically significant disease resolution in the second pivotal trial of TP-03,” said Yizhe Wang, Ph.D., chief executive officer of LianBio. “These data reinforce TP-03’s potential to become the standard of care for the treatment of Demodex blepharitis. We estimate there are approximately 43 million patients with Demodex blepharitis in China, and there are currently no therapies approved in China for these patients. We look forward to initiating our planned Phase 3 study of TP-03 in China.”

LianBio licensed rights from Tarsus in March 2021 for the development and commercialization of TP-03 in Greater China. LianBio expects to initiate a registrational Phase 3 clinical trial of TP-03 in the second half of 2022 to support regulatory approval in China.

About TP-03
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 anti-parasitic agent that paralyzes and 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 hair follicle where the mites reside. Tarsus has evaluated TP-03 in two pivotal trials, including Saturn-2, collectively involving 833 patients. Both trials met the primary and all secondary endpoints, with statistical significance and no serious treatment-related adverse events. If approved, TP-03 may offer treatment for millions of patients with Demodex blepharitis.

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.
