IRVINE, Calif., May 6, 2026 (GLOBE NEWSWIRE) -- Tarsus Pharmaceuticals, Inc. (NASDAQ: TARS), today announced financial results for the first quarter ended March 31, 2026.

“XDEMVY is driving a fundamental shift in how Demodex blepharitis is diagnosed and treated,” said Bobak Azamian, M.D., Ph.D., Chief Executive Officer and Chairman of Tarsus. “As we look across the business, every key signal is gaining momentum, and we are seeing the market expand as a result – reinforcing XDEMVY’s expected growth trajectory toward potential peak sales exceeding $2 billion. Equally as exciting, XDEMVY validates a repeatable playbook for category creation. We are now scaling that approach across our pipeline, with several catalysts ahead that we believe will drive the next phase of growth and establish new standards of care.”

Recent Business and Clinical Highlights

•XDEMVY continues to be one of the best-selling prescription eye drops.

◦Net product sales were $145.4 million for the first quarter, a year-over-year increase of more than 85%.

◦Continued depth of prescribing as eye care professionals (ECPs) broaden screening and treatment across a wider range of patients.

•Direct-to-Consumer (DTC) campaign drove tremendous engagement and generated an increasingly positive and growing return on investment.

◦Continued to drive millions of visitors to XDEMVY.com and increased high-value actions on the website by approximately 40% quarter-over-quarter reflecting strong patient activation and conversion.

•On track to activate approximately 20 new Key Account Leaders by Q3 2026 focusing on driving deeper utilization within high-opportunity eye care practices.

•Tarsus maintained strong engagement across key ophthalmology and optometry conferences in the first quarter, presenting numerous data sets that reinforce the clinical importance of diagnosing and treating Demodex blepharitis (DB) and expand how ECPs identify and treat DB.

•Tarsus continues to execute on its robust pipeline of category-creating potential therapeutics.

◦Initiated Calliope, a Phase 2 trial evaluating TP-05, a novel investigational lotilaner-based oral prophylactic designed to kill ticks before potential disease transmission. Topline data is expected in the first half of 2027, with the potential to support a Phase 3-ready package.

◦The Phase 2 trial evaluating TP-04, a lotilaner-based sterile ophthalmic gel formulation for the potential treatment of ocular rosacea, continues to progress, with topline data expected in the first half of 2027.

•TP-03 (XDEMVY) for the treatment of Demodex blepharitis expanded globally.

◦Our out-license partner in Greater China, Grand Pharmaceuticals Group Ltd., achieved regulatory approval in the People’s Republic of China, triggering a $15 million milestone payment to Tarsus.

◦In Europe, we remain on track to complete stability work of a preservative-free formulation in 2026 and continue to evaluate a potential path to approval.

◦Ongoing discussions continue with regulatory authorities in Japan on a potential path to approval.

First Quarter 2026 Financial Results

•    Product sales, net: were $145.4 million compared to $78.3 million for the same period in 2025, driven by higher volume and improvements in the gross-to-net discount.

•    License fees and collaboration revenue: were $16.7 million related to a $15.0 million regulatory milestone achieved under the China Out-License and $1.7 million of required China withholding tax associated with this milestone. The milestone payment was recorded on a gross basis, which increased license fees and collaboration revenue by $1.7 million, with an equal offsetting amount recorded as foreign tax expense within provision for income taxes. There were no license fees and collaboration revenue in the same period in 2025.

•    Cost of sales: were $9.4 million compared to $5.2 million for the same period in 2025, due to manufacturing costs related to XDEMVY, the royalty Tarsus pays on net product sales, and amortization expense for the milestone payments made to our licensor, which is being amortized over its remaining useful life.
