The data provide support that continued treatment with VIASKIN Peanut showed further improvement through 36 months of treatment across all efficacy parameters....In the EPITOPE OLE, VIASKIN Peanut data suggests further improvement through 36 months of treatment across all efficacy parameters. Key data highlights include: 266 EPITOPE participants enrolled in the OLE; 211 underwent the Month 36 DBPCFC (n=149 VP250; n=62 placebo). After three years of VP250, 83.5% of participants reached an eliciting dose (ED) of ≥1000 mg, an increase from 64.2% at month 12 (the EPITOPE study)."

Epicutaneous immunotherapy for the treatment of peanut allergy. (PubMed, Allergy) - "Numerous clinical studies of Viaskin Peanut have demonstrated desensitization and reductions in reaction severity, particularly in children aged 1 through 11 years, as well as a favorable safety profile with mostly mild-to-moderate skin reactions that were observed to decrease over time. EPIT with Viaskin Peanut may be a potential therapeutic option for peanut allergy that is clinically practical with long-term efficacy and tolerability."

Long-term Safety Results of Epicutaneous Immunotherapy (EPIT) with Viaskin Peanut in Peanut-Allergic Children Aged 4-11 Years in the Phase 3 PEOPLE Study (AAAAI 2024) - "Treatment-related TEAEs leading to epinephrine use occurred in 1/87 (1.1%) participants (Year 1 only). VP250 treatment over 5 years in PEOPLE showed decreasing frequency and severity of TEAEs, no new safety signals, and high treatment compliance. These data suggest long-term VP250 treatment in peanut-allergic children may have a favorable safety and tolerability profile, which may facilitate its use over multiple years of treatment."
