Tarsus Pharmaceuticals, Inc. (NASDAQ: TARS), whose mission is to focus on unmet needs and apply proven science and new technology to revolutionize treatment for patients, starting with eye care, today announced the launch of a new direct-to-consumer TV campaign for XDEMVY® (lotilaner ophthalmic solution) 0.25%, the first and only FDA approved treatment for Demodex blepharitis (DB).

Demodex blepharitis occurs when Demodex mites – the most common ectoparasites found on humans – overpopulate on the eyelids. This infestation results in eyelid redness, crusties (collarettes), itching, irritation, misdirected eyelashes and inflammation. People with Demodex blepharitis often have difficulty applying makeup or driving at night, and many with the disease report being conscious of their eyes all day.

The first-of-its-kind campaign, called “Your Mitey Problem,” provides viewers with an inside look at a Demodex mite ‘party’ taking place on a patient’s eyelids. The uninvited eyelid squatters are feasting on oily sebum, clawing onto eyelashes and leaving behind a trail of waste, eyelid redness and inflammation. The chief of irritation is actress Betsy Sodaro – from CBS’s sitcom ‘Ghosts’ – who, in costume, encourages the other mites to wreak havoc on the eyelids.

Category-creating XDEMVY represents a significant step forward in eye care, and this campaign leverages dynamic visuals to describe the damaging impact potential of Demodex blepharitis on the eyelids. The goal of the campaign is to support patients in understanding their disease and drive them to consult with an eye care provider to see if XDEMVY is right for them.

“For years, millions of patients with Demodex blepharitis have struggled with limited, suboptimal treatment options and the frustration of not being able to address the root cause of their disease,” said Aziz Mottiwala, Chief Commercial Officer of Tarsus. “This engaging campaign educates patients on both the cause of disease and the only FDA-approved solution, and it does so with compelling visuals, action-oriented messaging and just the right amount of humor and levity. We are excited to reach patients directly with a fun, inspirational message that encourages them to prioritize their eyelid health and see an eye care provider.”

“Disease education has always been a critical part of our XDEMVY commercial strategy, and each of our campaigns has driven action and delivered significant, lasting impact among providers and patients,” said Bobak Azamian, M.D., Ph.D., CEO and Chairman of Tarsus. “With this new highly innovative and exciting campaign, we are bringing relatable, memorable and motivating messaging directly to patients. It is yet another example of our category-creating approach and we look forward to reaching an even greater number of patients in need.”

The multi-channel campaign is currently live on connected TV devices and streaming channels and will also include digital and social media components. The full TV spot can be viewed by visiting www.xdemvy.com.

About Demodex Blepharitis

Blepharitis is a common lid margin disease that is characterized by eyelid margin inflammation, redness and ocular irritation. Demodex blepharitis is caused by an infestation of Demodex mites, the most common ectoparasite found on humans and accounts for over two-thirds of all blepharitis cases. 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 mite infestation, and that at least 45 million people annually visit an eye care clinic. Demodex blepharitis can have a significant clinical burden and negative impact on patients’ daily lives.

About XDEMVY®

XDEMVY (lotilaner ophthalmic solution) 0.25%, formerly known as TP-03, is a novel prescription eye drop for the treatment of Demodex blepharitis and is designed to target and eradicate the root cause of the disease – Demodex mite infestation. The active ingredient in XDEMVY is lotilaner, 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 eyelash follicles where the mites reside. XDEMVY was evaluated in two pivotal trials 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 XDEMVY to be neutral to very comfortable. The most common ocular adverse reactions observed in the studies were 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.
