IRVINE, Calif., May 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 first quarter ended March 31, 2023, and recent business achievements.

“We are off to a tremendous start this year highlighted by the progress and execution of our commercial strategy as we prepare for the potential launch of TP-03 in the fall,” said Bobak Azamian, M.D., Ph.D., Chief Executive Officer and Chairman of Tarsus. “TP-03 has the potential, if approved, to be the first FDA-approved treatment and standard of care for Demodex blepharitis, a prevalent eyelid condition that affects approximately 25 million patients in the United States. We look forward to providing an update on our expected commercial launch plans during our virtual event in June. In tandem, we have continued to advance our broad pipeline into proof-of-concept studies. Enrollment is ongoing in our Phase 2a rosacea trial of TP-04, and we remain on-track to provide readouts from our Phase 2a trials in Lyme disease prevention and Meibomian Gland Disease.”

Recent Business Highlights and Corporate Update

• Demodex Expert Panel on Treatment and Eyelid Health (DEPTH) published two papers on the importance of diagnosis and management of Demodex blepharitis (DB) Eye; https://doi.org/10.1038/s41433-023-02500-4
  • Clinical diagnosis and management of DB: established consensus about the disease, including signs, symptoms and diagnosis
  • DEPTH consensus regarding current clinical practice management options for DB: collarettes are pathognomonic, patients with >10 collarettes should be treated even in the absence of symptoms; efficacy can be tracked by collarette resolution
  • DEPTH panel consensus was obtained by using the Delphi methodology, an approach that allows experts to achieve consensus by performing qualitative and quantitative analyses and utilizing sequential surveys

• Presented health economics data (Academy of Managed Care Pharmacy 2023) that suggests a costly, substantial burden of illness in patients with DB and the need for a safe, effective, FDA-approved treatment
  • Ongoing disease impact and additional office visits are potentially driving up healthcare resource utilization
  • Patients reported having delayed diagnosis, multiple office visits, unresolved DB and high costs of disease management
  • Current non-FDA approved therapies to manage DB do not address the root problem or provide satisfactory relief for most patients

• Awareness, Trial and Usage (ATU) market research survey of ~250 optometrists and ophthalmologists to capture and analyze awareness and likelihood to prescribe a potential prescription therapeutic for DB
  • Growing confidence in making a diagnosis with 68% believing collarettes are pathognomonic to DB and 66% recognizing the importance of screening patients for the presence of collarettes during eye exams
  • 93% indicated they would prescribe an FDA-approved therapeutic for DB

• Disease education campaigns driving awareness on the prevalence and impact of DB
  • “Look at the Lids” disease education campaign has generated nearly 200K unique website visits, up from 125K last quarter and more than 2.3M digital/media impressions, an increase of 300K impressions since last quarter
  • Launched “Don’t Freak Out. Get Checked Out.”, a disease education campaign designed to encourage patients who may have DB to visit their eye care provider for an eyelid check

• Continuing to engage with top commercial and Medicare accounts, educating on Demodex blepharitis, prevalence and potential health economic value

• Salesforce infrastructure in place: VP of Sales, two regional directors and 11 district managers
  • Focused sales force targeting ~15K optometrists and ophthalmologists, which represents >80% of the market; planned to activate upon potential FDA approval of TP-03

• Appointed Jeff Farrow as Chief Financial Officer and Chief Strategy Officer

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 obtain regulatory approval for and successfully commercialize TP-03 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 any commercialization of its product candidates, if approved; Tarsus is heavily dependent on the success of its lead product candidate, TP-03 for the treatment of Demodex blepharitis; the COVID-19 pandemic may affect Tarsus’ ability to initiate and complete preclinical studies and clinical trials, disrupt regulatory activities, disrupt manufacturing and supply chain or have other adverse effects on Tarsus’ business and operations; 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 Tarsus’ product candidates, particularly TP-03 for the treatment of Demodex blepharitis and 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 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.
