IRVINE, Calif., Aug. 04, 2021 (GLOBE NEWSWIRE) -- Tarsus Pharmaceuticals, Inc. (NASDAQ: TARS), a late clinical-stage biopharmaceutical company 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 and provided business and clinical updates for the quarter ended June 30, 2021.

“We have achieved significant milestones on our lead product and pipeline so far in 2021 with the positive read-out of the Saturn-1 data for TP-03 in Demodex blepharitis, the initiation of Saturn-2, and the initiation of the Callisto trial of TP-05 for the prevention of Lyme disease,” said Bobak Azamian, M.D., Ph.D., President and Chief Executive Officer of Tarsus. “Interest from the physician community also continues to build, as new Saturn-1 data presented at the ASCRS 2021 Annual Meeting reinforced the strong potential clinical utility of TP-03 with a broad range of patients showing a substantial response. Additionally, results from the Titan and Atlas studies reinforce the prevalence and burden of Demodex blepharitis, suggesting that this disease could affect as many as 25 million Americans, with 80% of patients reporting a negative impact on daily life. We believe this data supports both the need and opportunity for an FDA-approved therapeutic treatment option.”

Recent Business Highlights and Corporate Update:

• Announced positive results of the Phase 2b/3 Saturn-1 pivotal trial studying TP-03 (lotilaner ophthalmic solution, 0.25%) in patients with Demodex blepharitis. All pre-specified primary and secondary endpoints were met, and complete resolution of Demodex blepharitis signs was demonstrated in many patients treated with TP-03 (lotilaner ophthalmic solution, 0.25%).
  
  
  • 81% of patients on TP-03 achieved a clinically meaningful collarette cure, defined as 0-10 collarettes per lid at day 43 compared to 23% of those on vehicle (p<0.0001).
    
  • 44% of patients on TP-03 achieved the primary endpoint of complete collarette cure, defined as 0-2 collarettes per lid at day 43, compared to 7% on vehicle (p<0.0001).
  • 68% of patients on TP-03 achieved mite eradication defined as 0 mites per lash at day 43, compared to 18% on vehicle (p<0.0001).
  • Additionally, significant efficacy in lid erythema (redness) was demonstrated across multiple measures including complete and clinically meaningful composite cures, and in erythema alone. Results showed 45% of patients improved erythema by one (1) grade or more (compared to 28% of patients on vehicle, p=0.0002) and 19% of patients on TP-03 achieved a complete erythema cure (compared to 7% of patients on vehicle, p<0.0001).
  • TP-03 was well tolerated with a safety profile similar to the vehicle group. Additionally, the vast majority of TP-03 patients (92%) reported that the drop comfort was neutral to very comfortable. There were no serious treatment-related adverse events nor any treatment-related adverse events leading to treatment discontinuation.
    
    
• Released new data from the Saturn-1 Phase 2b/3 pivotal trial at the ASCRS 2021 Annual Meeting. The new Saturn-1 data reinforces the strong potential clinical utility of TP-03 for the treatment of Demodex blepharitis, with a broad range of patients showing a substantial response.
  
  
  • 95% of TP-03 patients showed a significant improvement in mite count, achieving ≤0.5 mites per lash at day 43 from an average baseline of 3.2 mites per lash, compared to 36% of those on vehicle (p<0.0001).
    
  • 93% of TP-03 patients improved by at least one collarette grade or approximately 50 collarettes per lid by day 43, from an average baseline of grade 2.8 or approximately 100 collarettes per lid, compared to 50% of those on vehicle (p<0.0001).
  • An additional Saturn-1 safety analysis also revealed that TP-03 had no clinically significant effect on multiple safety measures including Corrected Distance Visual Acuity (CDVA), corneal staining, and intraocular pressure (IOP), and no significant findings from slit lamp biomicroscopy or fundus exam. In addition, no impact to endothelial cell density (ECD) was seen in a subset of 21 patients. ECD will be further evaluated as part of the Saturn-2 trial plan.
    
    
• Presented data from the Titan real world prevalence study at the ASCRS meeting. The Titan study is an IRB-approved, retrospective chart review of 1,032 patients across six U.S.-based ophthalmology and optometry practices, designed to better understand the prevalence of collarettes in U.S. eye care clinics. Collarettes, or cylindrical dandruff, are a pathognomonic sign of Demodex blepharitis and are an accumulation of mite waste product and eggs that form at the base of the eyelashes. In data presented at ASCRS, the Titan study revealed the presence of collarettes in 58% (n=595) of patients. When projected across the U.S. population, these results suggest that Demodex blepharitis could affect as many as 25 million Americans. The study also revealed that the prevalence of Demodex blepharitis is similar to that of dry eye (58%, n=593).
  
  
• Commenced enrollment in Saturn-2, the second pivotal trial evaluating TP-03 for the treatment of Demodex blepharitis.   Saturn-2 is a randomized, controlled, multicenter, double-masked trial studying the safety and efficacy of TP-03. The trial is expected to enroll 418 participants and has a similar design to Saturn-1. Saturn-2’s primary endpoint is the proportion of patients achieving collarette cure, defined as 0 to 2 collarettes per lid. Secondary endpoints include the eradication of Demodex mites and the proportion of patients achieving a cure based on a composite of collarette cure and erythema cure (eyelid redness). Topline results for the study are anticipated in Q1 of 2022.
  
  
• Initiated the Phase 1 Callisto trial of TP-05, a novel, oral, non-vaccine therapeutic, for the prevention of Lyme disease and malaria. The Phase 1 Callisto trial is a single ascending dose and multiple ascending dose trial designed to evaluate the safety, tolerability, and pharmacokinetics (PK) of TP-05 in healthy volunteers. There are currently no U.S. Food and Drug Administration (FDA)-approved pharmacological prophylactic options for Lyme disease, which is the most common vector-borne disease in the United States, transmitted to humans through the infection of the bacterium Borrelia burgdorferi following the bite of a tick vector.
  
  
• Presented data from the Atlas study at the virtual Association for Research in Vision and Ophthalmology (ARVO) 2021 Annual Meeting.   The Atlas study is believed to be the first multi-center observational study to evaluate the functional and psychosocial impact of Demodex blepharitis, along with clinical manifestations, in adult patients. Overall, the study showed that Demodex blepharitis is associated with a significant symptomatic and psychosocial burden, negatively affecting daily life in the majority (80%) of patients with the disease.
  
  
• Received $35 million in proceeds as part of the partnership with LianBio; an additional $20 million is expected in Q3 2021 for clinical milestones achieved in June 2021.
