New Peer-Reviewed Publication Confirms Unprecedented Response Rates for STRATA’s Excimer Laser Combined with JAK Inhibitors in Pediatric Vitiligo
The study, conducted across five leading academic dermatology centers in
KEY STUDY FINDINGS
- Overall response rate of 85.5% in the JAK inhibitor + excimer laser group versus 53.8% in the tacrolimus + excimer laser control group (P<.001)
- Face and neck lesions achieved a 97.3% response rate in Group A, including a 64.9% “significantly effective” rate, compared to 59.5% in controls
- Trunk and limb response rates of 89.3% and 88.9%, respectively, versus 61.6% and 64.9% in controls
- 33 lesions in the combination group achieved >95% repigmentation by week 48, compared to only 3 in the control arm
- Mixed-effects modeling confirmed a statistically significant 21.7% higher repigmentation rate for the JAK inhibitor + excimer laser combination (β = 0.217, 95% CI: 0.204–0.230, P<.001)
- All adverse events were mild to moderate in severity and fully resolved with appropriate management; no cases of tuberculosis or hepatitis B/C were observed
- Quality of life improvements, measured by the Children’s Dermatology Life Quality Index, were significantly greater in Group A, reaching statistical significance by week 48 (P<.001)
“This publication is a powerful validation of our personalized medicine approach and confirms what we have long believed — that the XTRAC® excimer laser is not just a stand-alone therapy, but an essential, synergistic component of next-generation combination regimens. XTRAC®- 308-nm excimer laser served as the phototherapy backbone for both arms, underscoring its central and indispensable role in modern vitiligo combination therapy.” said Dr.
The mechanistic basis for these results reflects the complementary action of both therapies: JAK inhibitors suppress the upstream IFN-γ/JAK-STAT1 autoimmune signaling cascade that drives melanocyte destruction, while the 308-nm excimer laser simultaneously induces targeted apoptosis of pathogenic T cells at the dermo epidermal junction and actively promotes melanocyte migration and repopulation within lesional skin. Together, these mechanisms address both the immunological and cellular dimensions of vitiligo in a true personalized medicine approach.
Intellectual Property Portfolio
STRATA’s growing portfolio of patent applications is designed to support intellectual property protection and potential market exclusivity for combination therapies involving its XTRAC® excimer laser when used with JAK inhibitors, systemic agents, and biologic drugs. These pending or applied-for patents underpin STRATA’s strategy to expand into new clinical indications, including vitiligo and other inflammatory and autoimmune skin conditions.
“It is important that we continue to grow our market by expanding into new indications, while maximizing revenue opportunities for the Company and our partner clinics,” said Dr.
Further, the importance of these patent fillings lies in their pioneering role in defining and protecting the combined use of Excimer laser therapy with systemic pharmacologic agents, a significant advancement in the treatment of inflammatory and autoimmune skin diseases such as psoriasis, atopic dermatitis, leukoderma, alopecia areata, and vitiligo. Excimer lasers, particularly at 308 nm, allow for precise, high-dose, localized UVB exposure, delivering therapeutic light energy to affected skin areas while sparing healthy tissue. When used alone, they provide rapid lesion clearance, but their effects may be short-lived in severe or systemic disease. These pending patents strategically address these limitations by combining phototherapy with systemic treatments—including biologic drugs and JAK inhibitors—to deliver a synergistic therapeutic effect, ranging from enhanced treatment response including prolonged remission, potential reduction of the dosage for these drugs, as well as improved safety by limiting the UV exposure to only the affected skin area.
