Management to host conference call today, November 9, 2023, at 1:30 p.m. P.T. / 4:30 p.m. E.T.

IRVINE, Calif., Nov. 09, 2023 (GLOBE NEWSWIRE) -- 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 financial results for the third quarter ended September 30, 2023, and recent business achievements.

“We are proud to be able to bring XDEMVY to the millions of people suffering from Demodex blepharitis, who, until recently, have been living without an effective, FDA-approved treatment option,” said Bobak Azamian, M.D., Ph.D., Chief Executive Officer and Chairman of Tarsus. “The XDEMVY launch is off to a strong start and we are encouraged by the early momentum among eye care providers and patients we have generated in just the first few weeks of availability.”

Recent Business Highlights

  • On July 24, XDEMVY® was approved by the U.S. Food and Drug Administration (FDA) as the first and only therapeutic for Demodex blepharitis (DB), a highly prevalent eyelid disease that impacts approximately 25 million eye care patients in the U.S. It was approved a month prior to the PDUFA date and launched on August 24.
    • XDEMVY targets the root cause of DB and in pivotal trials demonstrated significant improvement in eyelids (reduction of collarettes, the pathognomonic sign of the disease, to no more than 2 collarettes per upper lid), mite eradication (mite density of 0 mites per lash) and erythema cure (Grade 0).
  • Saturn-2 data were delivered as encore presentations at the American Academy of Optometry and American Academy of Ophthalmology conferences.
  • XDEMVY was added to the American Academy of Ophthalmology’s Preferred Practice Pattern (PPP) guidelines as the first and only FDA-approved therapeutic for the treatment of Demodex blepharitis.
  • In the third quarter of 2023:
    • XDEMVY generated $1.7 million in net product sales
    • ~1,700 bottles of XDEMVY were delivered to patients
    • Recognized a better than anticipated gross-to-net discount of 73%.
  • The Company’s expansive disease education efforts continue to drive awareness among eye care providers (ECPs) and action in proactively diagnosing DB.
  • Contract discussions with key commercial and Medicare accounts remain ongoing
    • Expect to secure broad commercial coverage sequentially throughout 2024 and Medicare coverage in 2025

Achieved and Anticipated 2023 and 2024 Milestones

Program Milestone Anticipated Indication H2 2023 Q1 2024
XDEMVY FDA Approval Demodex blepharitis X  
TP-03 Topline Phase 2a (Ersa) Meibomian Gland Disease  
TP-04 Topline Phase 2a (Galatea) Rosacea  
TP-05 Topline Phase 2a (Carpo) Lyme Disease Prevention  


Third Quarter 2023 Financial Results

  • Total revenues were $1.9 million, driven primarily by $1.7 million in net product sales, representing five weeks of sales following the launch of XDEMVY in late August.
  • Cost of sales were $0.4 million, due to manufacturing costs incurred after the approval of XDEMVY, period costs associated with launching one month earlier than expected, the royalty we pay on net product sales and the amortization of the $4.0 million approval milestone we paid to our licensor and are amortizing over a 10-year period.
  • Research and development (R&D) expenses were $12.1 million for the third quarter of 2023 compared to $10.9 million for the same period in 2022. The increase was due to $2.8 million of payroll expense (including non-cash stock-based compensation), partially offset by $1.9 million of program spend for TP-03. Total R&D non-cash stock compensation expense incurred in the third quarter of 2023, was $1.7 million, compared with $1.0 million in the same period in 2022.
  • Selling, general and administrative (SG&A) expenses were $30.3 million for the third quarter of 2023 compared to $12.0 million for the same period in 2022. The increase was due primarily to $7.9 million of payroll expense and $8.1 million of commercial and market research costs related to our commercial launch of XDEMVY. Total SG&A non-cash stock compensation expense incurred in the third quarter of 2023, was $3.6 million, compared with $2.6 million in the same period in 2022.
  • Net loss for the third quarter of 2023 was $39.1 million, compared to a net loss of $22.5 million for the same period in 2022. Basic and diluted net loss per share for the quarter ended September 30, 2023 was $(1.28), compared with $(0.84) for the same period in 2022.
  • As of September 30, 2023, cash, cash equivalents and marketable securities were $246.9 million, which includes the receipt of $99.4 million of net proceeds received from our follow-on offering completed in August 2023.

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 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. The Titan study also showed that management tools prior to the approval of XDEMVY, such as tea tree oil and lid wipes, are ineffective at targeting the root cause of Demodex blepharitis.

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 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 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 Indication and Important Safety Information

XDEMVY is indicated for the treatment of Demodex blepharitis.

Most common side effects: The most common side effect in clinical trials was stinging and burning in 10% of patients. Other side effects in less than 2% of patients were chalazion/hordeolum and punctate keratitis.

Forward-Looking Statements

Statements in this press release about future expectations, plans and prospects, as well as any other statements regarding matters that are not historical facts, may constitute “forward-looking statements.” These statements include statements regarding the market size, acceptance, demand, prescription fill rate and adoption rate for XDEMVY; our ability to achieve distribution and patient access for XDEMVY and timing and breadth of payer coverage; our ability to continue to educate the market about Demodex blepharitis, the timing, objectives, and results of the clinical trials, anticipated regulatory and development milestones, our ability to continue investing in our business, and the quotations of Tarsus’ management. The words, without limitation, “believe,” “contemplate,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “potential,” “predict,” “project,” “should,” “target,” “will,” or “would,” or the negative of these terms or other similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these or similar identifying words. Actual results may differ materially from those indicated by such forward-looking statements as a result of various important factors. Important factors that could cause actual results to differ materially from those in the forward-looking statements include: Tarsus’ ability to maintain regulatory approval for and successfully commercialize XDEMVY for the treatment of Demodex blepharitis, Tarsus has incurred significant losses and negative cash flows from operations since inception and anticipates that it will continue to incur significant expenses and losses for the foreseeable future; Tarsus may need to obtain additional funding to complete the development and commercialization of its product candidates, if approved; Tarsus is heavily dependent on the success of its lead product, XDEMVY for the treatment of Demodex blepharitis; even if TP-03, TP-04, TP-05, or any other product candidate that Tarsus develops receives marketing approval, Tarsus may not be successful in educating healthcare professionals and the market about the need for treatments specifically for Demodex blepharitis, MGD, rosacea, Lyme disease prevention, and/or other diseases or conditions targeted by Tarsus’ products; the development and commercialization of Tarsus products is dependent on intellectual property it licenses from Elanco Tiergesundheit AG; Tarsus will need to develop and expand the company and Tarsus may encounter difficulties in managing its growth, which could disrupt its operations; the sizes of the market opportunity for XDEMVY and Tarsus’ product candidates, particularly TP-03 for the treatment of MGD, TP-04 for the treatment of Rosacea, as well as TP-05 for the prevention of Lyme disease, have not been established with precision and may be smaller than estimated; the results of Tarsus’ earlier studies and trials may not be predictive of future results; any termination or suspension of, or delays in the commencement or completion of, Tarsus’ planned clinical trials could result in increased costs, delay or limit its ability to generate revenue and adversely affect its commercial prospects; if Tarsus is unable to obtain and maintain sufficient intellectual property protection for its product candidates, or if the scope of the intellectual property protection is not sufficiently broad, Tarsus’ competitors could develop and commercialize products similar or identical to Tarsus’ products; and if Tarsus is unable to access capital (including but not limited to cash, cash equivalents, and credit facilities) and/or loses capital, as a result of potential failure of any financial institutions that Tarsus does business with directly or indirectly. Further, there are other risks and uncertainties that could cause actual results to differ from those set forth in the forward-looking statement and they are detailed from time to time in the reports Tarsus files with the Securities and Exchange Commission, including Tarsus’ Form 10-K for the year ended December 31, 2022 filed on March 17, 2023, the Form 10-Q for the quarter ended June 30, 2023 filed on August 10, 2023 and the most recent Form 10-Q quarterly filing filed with the SEC, which Tarsus incorporates by reference into this press release, copies of which are posted on its website and are available from Tarsus without charge. However, new risk factors and uncertainties may emerge from time to time, and it is not possible to predict all risk factors and uncertainties. Accordingly, readers are cautioned not to place undue reliance on these forward-looking statements. Any forward-looking statements contained in this press release are based on the current expectations of Tarsus’ management team and speak only as of the date hereof, and Tarsus specifically disclaims any obligation to update any forward-looking statement, whether as a result of new information, future events or otherwise.
