IRVINE, Calif., May 14, 2026 (GLOBE NEWSWIRE) -- Tarsus Pharmaceuticals, Inc. (NASDAQ: TARS) today announced a new partnership with John Cena to raise awareness of Demodex blepharitis, a common but often overlooked eyelid disease caused by microscopic mites that live in and around the eyelashes. Cena’s story reflects the experience of millions who live with symptoms for years before seeking care and receiving a proper diagnosis.

As part of this campaign, Cena will detail his own experience with Demodex blepharitis and XDEMVY® (lotilaner ophthalmic solution) 0.25%, the first and only FDA-approved treatment that directly targets and kills the mites that cause Demodex blepharitis.

“I suffered from eyelid redness, itching and crusting for years, chalking it up to long days on set under bright lights,” said Cena. “But it finally got to the point where I couldn’t ignore it any longer. My eye doctor diagnosed me with Demodex blepharitis, and I was relieved to finally understand what was causing my symptoms and to know there was an available treatment. After being prescribed XDEMVY, my eyelid mites were eliminated and my symptoms resolved. I’ve spent years pushing my body to the limit, but I hadn’t paid attention to my eye health. Now, I make eye exams a regular part of my routine.”

The campaign will roll out in the coming months via media interviews and social content highlighting Cena’s experience with eyelid mites, his experience with XDEMVY and his commitment to eye health.

“Too often, people ignore or even accept common eye symptoms like redness, itching and irritation, without realizing they may signal an underlying, treatable condition,” said Bobby Azamian, M.D., Ph.D., Chief Executive Officer and Chairman of Tarsus. “John’s story is relatable to millions who often overlook or neglect their eye health, and his candid perspective and understated humor help bring attention to a significant disease. Regular eye exams are critical, and we hope his experience encourages more people to recognize the signs, seek care and take their eye health seriously.”

Demodex blepharitis can be diagnosed during a routine eye exam, when an eye care provider asks the patient to look down to examine the eyelid margin for the presence of collarettes (crusting). One hundred percent of patients with collarettes have Demodex blepharitis. For more information about Demodex blepharitis and XDEMVY, visit 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 ectoparasites 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 designed to treat Demodex blepharitis by targeting and eradicating the root cause of the disease – Demodex mite infestation. XDEMVY was evaluated in two pivotal trials involving over 800 patients with twice-daily dosing for six weeks. Both trials met the primary endpoint and all secondary endpoints, with statistical significance and no serious treatment-related adverse events. Most patients found the XDEMVY eye drop to be neutral to very comfortable. The most common ocular adverse reactions observed in the studies were instillation 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.

XDEMVY® (lotilaner ophthalmic solution) 0.25% is FDA approved in the United States for the treatment of Demodex blepharitis. Tarsus is also developing TP-04 for the potential treatment of ocular rosacea and TP-05 as an oral tablet for the potential prevention of Lyme disease, both of which are in Phase 2.
