Tarsus Pharmaceuticals, Inc.

Previous wording

We are an early commercial stage biopharmaceutical company with a limited operating history and a single product approved for commercial sale. We have incurred significant losses and negative cash flows from operations since our inception and could continue to incur significant expenses and losses for the foreseeable future.

Current wording

We are a commercial stage biopharmaceutical company with a limited operating history and a single product approved for commercial sale. While we have generated revenue from the launch of XDEMVY® (lotilaner ophthalmic solution) 0.25%, we have continued to incur losses and negative cash flows from operations since our inception and anticipate that we could continue to incur significant expenses and potential losses in the future.

Previous wording

We have one product, XDEMVY®, formerly known as TP-03, which obtained Food Drug and Administration ("FDA") approval for the treatment of Demodex blepharitis in the U.S. in July 2023. We have incurred net losses each year since our company’s formation in 2016. We have funded our operations primarily from the sale and issuance of redeemable convertible preferred stock, convertible promissory notes and the sale of our common stock in our IPO, subsequent Follow-On Public Offerings, and under our Open Market Sale Agreement TM (the "2023 ATM Prospectus"), as well as proceeds from product sales, net, our China Out-License and draws from our Credit Facilities (as defined below). For the years ended December 31, 2024, 2023, and 2022, our net losses were $115.6 million, $135.9 million, and $62.1 million, respectively. As of December 31, 2024 and December 31, 2023, we had an accumulated deficit of $360.2 million and $244.7 million, respectively. Additionally, the net losses we incur may fluctuate significantly from quarter to quarter such that a period-to-period comparison of our results of operations may not be a good indicator of our future performance. The size of our future net losses will depend, in part, on the rate of future growth of our expenses and our ability to generate revenue. We initiated sales and marketing activities to commercialize XDEMVY in August 2023. We could potentially incur operating losses over the next several years and for the foreseeable future until our revenue from product sales from XDEMVY and any other approved products exceeds expenses, which may never occur. We may never achieve profitability and, even if we do, we may not be able to sustain or increase our profitability. Our prior losses, combined with expected future losses, have had and will continue to have an adverse effect on our accumulated deficit and working capital.

We currently rely, and for the foreseeable future will continue to rely, in substantial part on certain third-party contract organizations, advisors and consultants to provide certain services, including assuming substantial responsibilities for the conduct of our clinical trials and the manufacture of our product candidates. We cannot assure you that the services of such third-party contract organizations, advisors and consultants will continue to be available to us on a timely basis when needed, or that we can find qualified replacements. In addition, if we are unable to effectively manage our outsourced activities or if the quality or accuracy of the services provided by our vendors or consultants is compromised for any reason, our clinical trials may be extended, delayed or terminated, and we may not be able to successfully commercialize XDEMVY, obtain marketing approval of our product candidates or otherwise advance our business. We cannot assure you that we will be able to properly manage our existing vendors or consultants or find other competent outside vendors and consultants on economically reasonable terms, or at all.

Despite the implementation of security measures, given their size and complexity and the increasing amounts of confidential information that they maintain, our internal information technology systems and those of our third-party CROs, contract manufacturing organizations ("CMO"), and other contractors and consultants are potentially vulnerable to breakdown or other damage or interruption from service interruptions, system malfunction, natural disasters, interruptions or cyber incidents resulting from the conflict between Russia and Ukraine, conflict in the Middle East, terrorism, war and telecommunication and electrical failures, as well as security breaches from inadvertent or intentional actions by our employees, contractors, consultants, business partners, and/or other third parties, or from cyber-attacks by malicious third parties (including the deployment of harmful malware, ransomware, denial-of-service attacks, social engineering and other means to affect service reliability and threaten the confidentiality, integrity and availability of information), which may compromise our system infrastructure or lead to data leakage. Further, due to the political uncertainty involving Russia and Ukraine and conflict in the Middle East, there is an increased likelihood that escalation of tensions could result in cyber attacks that could either directly or indirectly impact our operations. To the extent that any disruption or security breach were to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability and reputational damage and the commercial operations of XDEMVY and further development of our product candidates could be delayed.

Previous wording

While we have not experienced any such system failure, accident or security breach to date, we cannot assure you that our data protection efforts and our investment in information technology and cybersecurity will prevent significant breakdowns, data leakages, breaches in our systems or other cyber incidents that could have a material adverse effect upon our reputation, business, operations or financial condition, whether due to a loss of our trade secrets or other proprietary information or other similar disruptions. Our inability to use or access our information systems at critical points in time could adversely affect the timely and efficient operation of our business. Any delayed sales, significant costs or lost customers resulting from these technology failures could adversely affect our business, operations, and financial results. For example, if such an event were to occur and cause interruptions in our operations, it could result in a material disruption to our commercial operations of XDEMVY and further development of our product candidates could be delayed. In addition, the loss of clinical trial data for our product candidates could result in delays in our marketing approval efforts and significantly increase our costs to recover or reproduce the data. Furthermore, significant disruptions of our information technology systems or security breaches could result in the loss, misappropriation, and/or unauthorized access, use, or disclosure of, or the prevention of access to, confidential information (including trade secrets or other intellectual property, proprietary business information, and personal information), which could result in financial, legal, business, and reputational harm to us. For example, any such event that leads to unauthorized access, use, or disclosure of personal information, including personal information regarding our clinical trial subjects or employees, could harm our reputation directly, compel us to comply with federal and/or state breach notification laws and foreign law equivalents, subject us to mandatory corrective action, and otherwise subject us to liability under laws and regulations that protect the privacy and security of personal information, including private lawsuits or class actions under the California Consumer Privacy Act "CCPA"), which could result in significant legal and financial exposure and reputational damages that could potentially have an adverse effect on our business.

The increasing use of AI technologies, including by us and by third-party vendors, may further increase cybersecurity and data protection risks, including through the processing of sensitive or confidential information in ways that may be difficult to monitor, control, or fully secure. Our inability to use or access our information systems at critical points in time could adversely affect the timely and efficient operation of our business. As another example, any data integrity failure could impact our ability to disclose legally required information such, as for example, payments made under the federal Physician Payments Sunshine Act (or similar state or foreign law equivalents), which requires applicable manufacturers of covered drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program, with specific exceptions, to annually report to Centers for Medicare & Medicaid Services (“CMS”) information regarding direct or indirect payments and other transfers of value to physicians and teaching hospitals (and certain other practitioners as of 2022), as well as information regarding ownership and investment interests held by physicians and their immediate family members, which could subject us to liability. Any delayed sales, significant costs or lost customers resulting from these technology failures could adversely affect our business, operations, and financial results.

Previous wording

Our results of operations could be adversely affected by general conditions in the global and geopolitical economy and in the global financial markets. Financial pressures may cause government or other third-party payers to more aggressively seek cost containment measures in healthcare and other settings. As a result of global economic conditions, some third-party payers may delay or be unable to satisfy their reimbursement obligations. Job losses or other economic hardships (including inflation) may also affect patients’ ability to afford healthcare as a result of increased co-pay or deductible obligations, greater cost sensitivity to existing co-pay or deductible obligations, lost healthcare insurance coverage or for other reasons. We believe such conditions have led and could continue to lead to reduced demand for our products, which could have a material adverse effect on our product sales, net, business and results of operations. The current inflationary environment related to increased aggregate demand, supply chain constraints and the effects from the armed conflict in Ukraine (including the effects of the sanctions that were implemented in response to the conflict and the resulting impacts on the commodity market and supply chains), and the current conflict in the Middle East, have also increased our operating expenses and may continue to affect our operating expenses. Our operational costs, including the cost of energy, materials, labor, distribution and our other operational and facilities costs are subject to market conditions and are being adversely affected by inflationary pressures. Global and geopolitical economic conditions may also adversely affect the ability of our distributors, customers and suppliers to obtain the liquidity required to buy inventory or raw materials and to perform their obligations under agreements with us, which could disrupt our operations. Although we monitor our distributors’, customers’ and suppliers’ financial condition and their liquidity to mitigate our business risks, some of our distributors, customers and suppliers may become insolvent, which could have a material adverse effect on our product sales, business and results of operations. A significant worsening of global and geopolitical economic conditions could precipitate or materially amplify the other risks described herein.

Previous wording

We received approval by the FDA for XDEMVY for the treatment of Demodex blepharitis in the U.S. and began generating revenue from product sales during the third quarter of 2023. Our ability to become and remain profitable is heavily dependent on our ability to continue to generate revenue from XDEMVY. The success of our commercialization will depend on a number of factors, including, among others, the continued development of our commercial organization, including our internal sales and marketing team and distribution capabilities, our ability to navigate the significant expenses and risks involved with the development and management of such capabilities, satisfying any post-marketing regulatory requirements, our ability to secure and maintain adequate healthcare coverage and the acceptance of XDEMVY by patients, eye care providers ("ECPs") and third-party payers. Further, our commercial success is dependent on our ability to educate ECPs, patients and others in the medical community about Demodex blepharitis. If XDEMVY, or any other future approved product, does not achieve an adequate level of acceptance, coverage, pricing or reimbursement, we may not generate significant revenue from product sales and we may not be profitable. Even if we successfully commercialize XDEMVY in the U.S., we may be unable to achieve or maintain profitability, unless XDEMVY is approved in other jurisdictions or for additional indications. Because of the uncertainties and risks associated with these activities, we are unable to accurately and precisely predict the timing and amount of revenues from product sales of XDEMVY, or any future approved products, or if or when we might achieve profitability.

Previous wording

We may not be successful in educating ECPs and the market about the need for treatments specifically for Demodex blepharitis and other diseases or conditions targeted by XDEMVY or our product candidates. XDEMVY or other product candidates that we may develop may fail to achieve market acceptance by ECPs, other healthcare providers and patients, or adequate formulary coverage, pricing or reimbursement by third-party payers and others in the medical community, and the market opportunity for these products may be smaller than we estimate.

Previous wording

XDEMVY, or any current or future product candidate that receives marketing approval, may fail to gain sufficient market acceptance by ECPs or other healthcare providers, patients, third-party payers and others in the medical community. Before the approval of XDEMVY, there was no FDA-approved prescription therapeutic for Demodex blepharitis and the only other current treatments include over-the-counter and off-label remedies such as tea tree oil, lid wipes and artificial tears, as well as off-label prescription products. Efforts to educate the medical community, patients and third-party payers on the benefits of XDEMVY and our other product candidates has required and may continue to require significant resources and we may not be successful.

Previous wording

Although XDEMVY is approved for the treatment of Demodex blepharitis, ECPs and potential patients may not have sufficient information about, or recognize the need for a treatment specifically targeting Demodex blepharitis. It is possible that ECPs may continue to rely on other treatments for treating symptoms consistent with Demodex blepharitis. A key tenet of our continued commercialization strategy is to educate ECPs on Demodex blepharitis and how to diagnose it with a simple slit lamp examination as well as raise patient awareness of Demodex blepharitis. However, our efforts may prove to be unsuccessful, and we may not be able to develop this new market for XDEMVY. We may still not achieve success in promotional efforts for XDEMVY, and ECPs may continue to use existing treatments rather than XDEMVY or any other product candidate and potential patients may not inquire as to XDEMVY. It is also possible that ECPs and patients may not be willing to adopt XDEMVY for the treatment of Demodex blepharitis because of the possibility that the disease will recur despite mite eradication, or after adoption fail to continue to use XDEMVY for the treatment of Demodex blepharitis.

We began commercializing our first product, XDEMVY, in the U.S. in July 2023. The success of our commercialization efforts for XDEMVY and any future approved products is subject to the effective execution of our business plan, including, among others, the continued development of our internal sales, marketing and distribution capabilities. For example, we have established an internal infrastructure as well as an ECP-focused sales and distribution infrastructure to market XDEMVY and our product candidates in the U.S., and have completed hiring in areas to support commercialization, including sales management, sales representatives, marketing, access and reimbursement, sales support and distribution. There are significant risks involved with establishing our own sales, marketing, and distribution capabilities, including our ability to hire, retain and appropriately incentivize qualified individuals, provide adequate training to sales and marketing personnel, and effectively manage geographically dispersed sales and marketing teams to generate sufficient demand. Any failure or delay in the development of these capabilities could or negatively affect the success of our commercialization efforts and business. For example, the commercialization of XDEMVY may not develop as planned or anticipated, which may require us to, among other items, adjust or amend our business plan and strategies and incur significant expenses.

Previous wording

Further, in order to continue to commercialize XDEMVY or commercialize any product candidates, if approved, we must continue to build marketing, sales, distribution, managerial and other non-technical capabilities or make arrangements with third parties to perform these services for each of the territories in which we may have approval to sell and market our product candidates.

The development and commercialization of new drug products is highly competitive. We face potential competition with respect to XDEMVY and our product candidates that we may seek to develop or commercialize in the future, from many different sources, including major pharmaceutical companies, specialty pharmaceutical companies and biotechnology companies worldwide and existing treatments. Potential competitors also include academic institutions, government agencies and other public and private research organizations that conduct research, seek patent protection and establish collaborative arrangements for research, development, manufacturing and commercialization.

For example, we are aware that Glaukos Corp. and Aperta Biosciences have initiated Phase 2 trials and Atticus Medical has publicly disclosed plans to initiate a Phase 2 trial, for the potential treatment of Demodex blepharitis. Potential competitors also include academic institutions, government agencies and other public and private research organizations that conduct research, seek patent protection and establish collaborative arrangements for research, development, manufacturing and commercialization.

Previous wording

In order to market any products, including XDEMVY, outside of the U.S., we will need to comply with additional onerous and varying regulatory requirements of other countries regarding safety and efficacy on a country-by-country basis. Approval by the FDA in the U.S. does not ensure approval by comparable regulatory authorities in other countries or jurisdictions nor does it ensure that we will be able to successfully commercialize XDEMVY or any other approved products in the U.S. or in other jurisdictions. In addition, clinical trials conducted in one country may not be accepted by regulatory authorities in other countries, and regulatory approval in one country does not mean that regulatory approval will be obtained in any other country. Further, successful commercialization in the U.S. does not guarantee successful commercialization in other jurisdictions. Approval procedures vary among countries and can involve additional product testing and validation and additional administrative review periods. Seeking foreign regulatory approvals could result in significant delays, difficulties and costs for us and may require additional preclinical studies or clinical trials which would be costly and time consuming. Regulatory requirements can vary widely from country to country and could delay or prevent the introduction of our products in those countries. Satisfying these and other regulatory requirements is costly, time consuming, uncertain and subject to unanticipated delays. In addition, our failure to obtain regulatory approval in any country may delay or have negative effects on the process for regulatory approval in other countries. We do not have any product candidates approved for sale in international markets, and we do not have experience in obtaining regulatory approval in international markets. If we, or our collaboration partners, fail to comply with regulatory requirements in international markets or to obtain and maintain required approvals, or if regulatory approvals in international markets are delayed, our ability to realize the full market potential of our products will be harmed.

Under the Medicaid Drug Rebate Program, a participating manufacturer is required to pay a rebate to each state Medicaid program for its covered outpatient drugs that are dispensed to Medicaid beneficiaries and paid for by the state Medicaid program as a condition of having federal funds being made available for drugs under Medicaid and Medicare Part B ("Medicare Part B"). Those rebates are based on pricing data reported by the manufacturer on a monthly and quarterly basis to to the Centers for Medicare and Medicaid Services ("CMS"). These data include the average manufacturer price and, in the case of innovator products, the best price for each drug, which, in general, represents the lowest price available from the manufacturer to any wholesaler, retailer, provider, health maintenance organization, nonprofit entity, or governmental entity in the U.S. in any pricing structure, calculated to include all sales and associated rebates, discounts, and other price concessions. If we fail to pay the required rebate amount or report pricing data on a timely basis, we may be subject to civil monetary penalties and/or termination from the Medicaid Drug Rebate Program. Additionally, civil monetary penalties can be applied if we are found to have knowingly submitted any false price or product information to the government, if we fail to submit the required price data on a timely basis, or if we misclassify or misreport product information. CMS could also decide to terminate our Medicaid Drug Rebate Program, in which case federal payments may not be available under Medicaid or Medicare Part B for our covered outpatient drugs.

The ACA (addressed further above in the section on “Business – Government Regulatory – Coverage and Reimbursement”) made significant changes to the Medicaid Drug Rebate Program, and CMS issued a final regulation to implement the changes to the Medicaid Drug Rebate Program under the ACA. CMS also issued a final regulation that modified prior Medicaid Drug Rebate Program regulations to permit reporting multiple best price figures with regard to value based purchasing arrangements; and provide definitions for “line extension,” “new formulation,” and related terms, with the practical effect of expanding the scope of drugs considered to be line extensions that are subject to an alternative rebate formula. While the regulatory provisions that purported to affect the applicability of the best price and average manufacturer price exclusions of manufacturer-sponsored patient benefit programs, in the context of pharmacy benefit managers ("PBM") “accumulator” and "maximizer" programs were invalidated by a court, such programs may continue to negatively affect us in other ways. Our failure to comply with these price reporting and rebate payment options, as well as PBM “accumulator” and "maximizer" programs, could negatively impact our financial results.

Federal law requires that a manufacturer also participate in the 340B Drug Pricing program "(340B program") in order for federal funds to be available for the manufacturer’s drugs under Medicaid and Medicare Part B. The 340B program requires participating manufacturers to agree to charge no more than the 340B “ceiling price” ("340B ceiling price) for the manufacturer’s covered outpatient drugs to a specified “covered entities,” including community health centers and other entities that receive certain federal grants, as well as hospitals that serve a disproportionate share of low-income patients. The 340B ceiling price is calculated using a statutory formula, which is based on the average manufacturer price and rebate amount for the covered outpatient drug as calculated under the Medicaid Drug Rebate Program. If we are found to have knowingly and intentionally charged 340B program covered entities more than the statutorily mandated ceiling price, we could be subject to significant civil monetary penalties and/or such failure also could be grounds for Health Resources and Services to terminate our agreement to participate in the 340B program, in which case our covered outpatient drugs would no longer be eligible for federal payment under the Medicaid or Medicare Part B program.

We accrue rebates for contractually agreed-upon discounts with commercial insurance companies and mandated discounts under government programs such as the Medicaid Drug Rebate Program, Medicare Part D, and other government health care programs in the U.S. Our estimates for expected utilization of commercial insurance rebates are based on data received from its customers. The Company's estimates for rebates under government programs are based on statutory discount rates and expected utilization as well as historical data it has accumulated since product launch. Our rebate calculations may require estimates, including estimates of customer mix, to determine which product sales will be subject to rebates and the amount of such rebates. We updates our estimates and assumptions on a quarterly basis and records any necessary adjustments to revenue in the period identified. Rebates are generally invoiced and paid in arrears so that the accrual balance consists of an estimate of the amount expected to be incurred for the current quarter’s activity, plus an accrual balance for known prior quarters’ unpaid rebates. If actual rebates vary from estimates, due to government invoicing delays or otherwise, we may need to adjust accruals, potentially adversely, which would affect product sales, net in the period of adjustment. An accrued liability is recorded for unpaid rebates related to product for which control has transferred to the customer.

The FCP is derived from a calculated price point called the “non-federal average manufacturer price” (“Non FAMP”), which the manufacturer calculates and reports to the VA on a quarterly and annual basis. Pursuant to applicable law, knowing provision of false information in connection with a Non FAMP filing can subject a manufacturer to significant penalties for each item of false information. The FSS contract also contains extensive disclosure and certification requirements. If we overcharge the government in connection with the FSS contract or Tricare Retail Pharmacy Rebate Program, whether due to a misstated FCP or otherwise, we will be required to refund the difference to the government. Failure to make necessary disclosures and/or to identify contract overcharges can result in allegations against us under the False Claims Act and other laws and regulations. Unexpected refunds to the government, and any response to government investigation or enforcement action, would be expensive and time-consuming, and could have a material adverse effect on our business, financial condition, results of operations and growth prospects.

Because we have limited financial and managerial resources, we must prioritize our research programs and will need to focus our product candidates on the potential treatment of certain indications. We are currently focused on the commercialization, of XDEMVY for the treatment of Demodex blepharitis. As a result, we may forego or delay pursuit of opportunities with other product candidates or for other indications that later prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on the most viable commercial products or profitable market opportunities. Our spending on current and future research and development programs for XDEMVY and other product candidates may not yield any commercially viable products. If we do not accurately evaluate the commercial potential or target market for XDEMVY for other indications and other product candidates, we may also relinquish valuable rights to that product candidate through collaboration, licensing or other royalty arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights to such product candidate.

We are early in our development efforts for our product candidates and indications, including TP-04 for the treatment of Ocular Rosacea and TP-05 for potential Lyme disease prophylaxis and community malaria reduction. The risk of failure for product candidates in early development is high. Extensive clinical trials are necessary to demonstrate the safety and efficacy of such product candidates in humans. Clinical trials may fail to demonstrate that such product candidates are safe for humans and effective for indicated uses. Further, we intend to leverage data from the TP-03 preclinical studies and clinical safety assessments for the treatment of Demodex blepharitis to satisfy the preclinical study requirements for TP-04 and TP-05 and other indications. For rosacea, we conducted the Phase 1 Galatea trial with TP-04 and initiated the Phase 2a Galatea trial, for the treatment of rosacea in March 2023. In February 2024, we announced positive topline results and in January 2025, we announced plans to initiate a Phase 2 study in the second half of 2025. With respect to Lyme disease, in December 2022 we announced positive topline results from the completed Callisto trial and enrollment of the first patient in the Carpo trial. The Carpo trial, evaluating TP-05, a novel investigational oral, non-vaccine pharmacological prophylactic for the potential prevention of Lyme disease in humans is a randomized, double-blind, placebo-controlled trial that evaluated the efficacy of TP-05 in killing lab grown, non-disease carrying ticks after they have attached to the skin of healthy volunteers, as well as confirm the safety, tolerability, and blood concentration of TP-05. In February 2024, we announced positive topline results from the Carpo trial. In December 2024, we met with the FDA about our Lyme disease program. The FDA agreed to our proposed approach for a Phase 2b clinical trial, which would include several hundred subjects. Additionally, the FDA confirmed that a Phase 3 clinical study would require a disease prevention field study that would likely require the enrollment of thousands of patients.
