TARS Tarsus Pharmaceuticals Inc

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, announces the launch of “Mite Party,” a dynamic, multi-channel consumer marketing campaign for XDEMVY® (lotilaner ophthalmic solution) 0.25%, the first and only FDA approved treatment for Demodex blepharitis. “Mite Party” is designed to elevate consumer awareness of Demodex blepharitis through relatable messaging and compelling visuals to encourage patients who may have Demodex blepharitis to seek out an eye care provider for screening.

“We are committed to increasing Demodex blepharitis education and awareness so that patients more effectively understand their disease and are motivated to seek treatment,” said Aziz Mottiwala, Chief Commercial Officer of Tarsus. “The memorable visuals and differentiated messaging in the ‘Mite Party’ campaign are designed to resonate with patients in a meaningful and action-oriented way. We look forward to advancing this novel campaign with the goal of helping as many patients with Demodex blepharitis as possible.”

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), irritation, misdirected eyelashes, and inflammation. The campaign is intended to help patients identify this infestation, or “mite party” on the eyelids and encourage them to see an eye doctor.

“Mite Party” will officially launch on the XDEMVY Facebook page (@xdemvyrx) with a live event designed to “break up the mite parties” on Demodex blepharitis patients’ eyelids. The Facebook event, scheduled for March 7, 2024 at 5pm PT, will feature Mitchell Shultz, MD, FAAO, and Amir Moarefi, MD as well as patients with Demodex blepharitis.

“I’ve seen Demodex in my practice for years, and often, patients come to me without a clear understanding of the disease or how it’s treated,” said Caroline Watson, MD, ophthalmologist at Alabama Vision Center. “The ‘Mite Party’ campaign not only provides education about the disease but also encourages important conversation with providers, and I’m eager to see the potential impact it has on the future diagnosis and treatment of Demodex blepharitis patients.”

The “Mite Party” campaign components are featured on www.xdemvy.com and include a “Find a Doctor” tool, an interactive quiz, real before and after results of patients treated with XDEMVY1, and other educational information and resources.

“Demodex blepharitis is incredibly common, and I’m delighted that there is a campaign that makes this disease relevant and relatable to patients,” said Mark Schaeffer, OD, optometrist, Birmingham, Ala. “Now that we finally have an FDA-approved treatment for Demodex blepharitis with XDEMVY, we hope more patients will be able to associate how they’re feeling with the disease and proactively visit their eye care providers.”

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.
