STRATA Skin Sciences Receives Continued Validation for its Personalized Approach with New Published Study Highlighting XTRAC® Excimer Laser Treatment Combined with a Topical Drug in Psoriasis

HORSHAM, Pa., Sept. 30, 2025 (GLOBE NEWSWIRE) -- STRATA Skin Sciences, Inc. (“STRATA” or the “Company”) (NASDAQ: SSKN), a medical technology company dedicated to developing, commercializing, and marketing innovative products for the treatment of dermatologic conditions, announces the publication of a new peer-reviewed study in Lasers in Medical Science that reinforces the Company’s commitment to personalized medicine. The study demonstrates that treatment using the Company’s XTRAC 308nm Excimer Laser in combination with 0.1% tacrolimus ointment significantly improves outcomes in patients with plaque-type psoriasis compared to topical monotherapy.

The study, titled “Clinical efficacy of 308 nm excimer laser irradiation combined with 0.1% tacrolimus ointment in the treatment of plaque-type psoriasis,” was authored by Xiaobin Gao, Shuhua Du, Jun Zeng, Yan Li, and Dan Shen and published in Lasers in Medical Science (2025, Vol. 40:342). DOI: /10.1007/s10103-025-04599-1.

Clinical Study Design Highlights Personalized Medicine in Action

The retrospective observational study involved 100 adult patients with plaque-type psoriasis treated between January 2023 and January 2024. Patients were divided into two equal groups:

- Control group (n=50), which received 0.1% tacrolimus ointment twice daily for 8 weeks

- Observation group (n=50), which received the same topical regimen plus phototherapy using the 308 nm Excimer Laser (XTRAC) twice weekly, using patient-specific dosing determined by their individual Minimum Erythema Dose (MED)

Key Findings: Personalized, Targeted Laser Therapy Enhances Efficacy

• PASI Reduction:
  • Control group: Mean PASI dropped from 18.62 to 5.23
  • Observation group: Mean PASI dropped from 18.36 to 3.30
  • The difference was statistically significant (p < 0.01), showing the combination therapy was markedly superior
• Safety Profile:
  • No serious adverse events in either group
  • Mild and self-resolving irritation or eczema reported in a small number of patients
• Personalization in Practice:
  • Individualized excimer laser dosing based on MED and plaque characteristics enabled targeted lesion treatment, maximizing benefit while minimizing exposure to healthy tissue—a fundamental principle of precision dermatology
• Mechanistic Synergy:
  • The combination works through complementary immunomodulatory pathways: the excimer laser induces apoptosis in pathogenic T-cells and suppresses keratinocyte hyperproliferation, while tacrolimus locally inhibits cytokine release through calcineurin inhibition. This resulted in faster resolution of plaques and enhanced patient outcomes
    
    

Dr. Dolev Rafaeli, STRATA’s President and CEO, commented, “This important new study highlights the relevance and scientific rigor behind our Excimer laser technology. As clinicians increasingly seek personalized, flexible, and safe treatment options, our XTRAC system continues to meet the moment by integrating seamlessly with topical and systemic therapies."



“With more than 400 clinical publications backing Excimer therapy and a strong safety track record, this newest publication adds further weight to our case with CMS to expand reimbursement, especially as demand for non-biologic, in-office treatment options continues to grow,” he added.

Broader Implications and Strategic Importance

This study reinforces STRATA’s strategic leadership in personalized, clinic-based dermatologic care as it:

• Supports Excimer laser’s use not only as monotherapy but also in conjunction with topical agents, biologics, and JAK inhibitors
• Validates STRATA’s combination therapy strategy
• Adds peer-reviewed evidence that strengthens provider and payer confidence
• Offers a cost-effective, targeted alternative to systemic immunosuppressants in selected patient populations
