Tarsus Pharmaceuticals, Inc. Presents New Saturn-1 Pivotal Trial Data and Titan Real-World Prevalence Study Results at ASCRS 2021 - Seite 4

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. TP-03 is a topical ophthalmic formulation of lotilaner, which is a well-characterized anti-parasitic agent that paralyzes and eradicates Demodex mites by selectively inhibiting parasite-specific GABA-Cl channels. It is a potent, non-competitive antagonist of insect and arachnid GABA-Cl channels and a highly lipophilic molecule, which may promote its uptake in the oily sebum of the hair follicle where the mites reside. TP-03 was evaluated in the pivotal Saturn-1 (Phase 2b/3) trial involving 421 patients and met all primary and secondary endpoints with no serious treatment-related adverse events and no treatment-related discontinuations. Prior to that, Tarsus also completed four Phase 2 clinical trials of TP-03 in Demodex blepharitis, all of which met their respective endpoints with no significant adverse events nor any events leading to treatment discontinuation. TP-03 is currently being evaluated in the Saturn-2 (Phase 3) pivotal trial. If approved, TP-03 may offer treatment for millions of patients around the world 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 blepharitis may affect as many as 25 million Americans based on an extrapolation from the Titan study indicating 58% of patients presenting to U.S. eye care clinics have collarettes, a pathognomonic sign of Demodex infestation, and another published study estimating that at least 45 million people annually visit an eye care clinic. Demodex blepharitis can have a significant clinical burden and negatively impact patients’ daily lives. Currently, there are no FDA-approved treatments for Demodex blepharitis.
