DBV Technologies Announces Positive Topline Results from Phase 3 VITESSE Trial of VIASKIN® Peanut Patch in Peanut Allergic Children Aged 4-7 Years
- VITESSE met its primary endpoint: the lower bound of the 95% confidence interval (CI) of the difference between treatment arms was 24.5%, exceeding the prespecified threshold of 15%
- 46.6% of children treated with the VIASKIN® Peanut patch met response criteria at 12 months, compared to 14.8% of children in the placebo arm
- Safety results were consistent with the safety profile observed in the VIASKIN Peanut clinical program to date
- BLA submission in 4-7-year-olds on track for the first half of 2026
- Achievement of primary endpoint triggers an acceleration of the exercise period of certain warrants issued pursuant to DBV’s March 2025 financing
- DBV to host a conference call today at 5:00 p.m. ET to discuss the VITESSE topline results and path forward
DBV Technologies (Euronext: DBV – ISIN: FR0010417345 – Nasdaq Stock Market: DBVT – CUSIP: 23306J309), a late-stage biopharmaceutical company, today announced that VITESSE, its pivotal Phase 3 study assessing the safety and efficacy of VIASKIN® Peanut patch for the treatment of peanut-allergic children aged 4 to 7 years, met its primary endpoint.
VIASKIN Peanut demonstrated a statistically significant treatment effect (p<0.001)*, with 46.6% of children in the VIASKIN Peanut arm meeting the treatment responder criteria after 12 months, as compared to 14.8% of children in the placebo arm (difference in response rates = 31.8%; 95% CI = (24.5, 39.0%)), exceeding the lower bound prespecified threshold of 15%.
Responders were defined as children with a baseline eliciting dose (ED) ≤30 mg who achieved an ED ≥300 mg of peanut protein at month 12, or a child with a baseline ED = 100 mg who achieved an ED ≥600 mg of peanut protein at month 12, as measured by a double-blind, placebo-controlled food challenge (DBPCFC). The ED is the amount of peanut protein that induced an allergic reaction. The month 12 responder rates for each ED sub-group performed as expected based on the Company’s statistical projections.
“Peanut allergy places a considerable burden on children and their families that is insufficiently addressed by current treatment options or strict avoidance,” stated David Fleischer M.D., Professor of Pediatrics at Children's Hospital Colorado and Global Principal Investigator of the VITESSE study. “I’m thrilled by these topline results which show a statistically significant treatment effect in children treated with the VIASKIN Peanut patch. The levels of desensitization achieved in this study after one year on treatment are highly clinically meaningful and represent substantial progress towards a well-tolerated, non-invasive potential option that I believe would be welcomed into pediatric care. As a practicing allergist, I look forward to what that may mean for families managing peanut allergy every day and hope to be able to implement this treatment in my clinic, if approved.”
VITESSE enrolled 654 children, exceeding its original enrollment target of 600, of which 438 and 216 were randomized to the active and placebo arms, respectively. Enrollment was balanced for age and baseline disease characteristics between the active and placebo treatment arms. Rates of enrollment in the VITESSE open-label extension were in line with previous VIASKIN Phase 3 studies.
Safety results were consistent with the safety profile of the VIASKIN Peanut clinical program to date. The most common treatment-emergent adverse events (TEAEs) observed during the VITESSE study were mild-to-moderate local skin reactions at the patch application site. Discontinuations due to TEAEs were low at 3.2% in the treatment arm compared to 0.5% of in the placebo arm. Notably, there were no reports of treatment-related serious adverse events and treatment-related anaphylaxis was low at 0.5% (n=2) – both children continued treatment. The data from the exploratory adhesion assessments were in line with the Company's expectations. Overall, compliance was high at 96.2%, consistent with what has been observed in other Phase 3 VIASKIN Peanut studies.
“We saw tremendous enthusiasm around EPIT and the VIASKIN Peanut patch development program at ACAAI’s annual scientific meeting last month” said allergist Cherie Zachary M.D., President of the American College of Allergy, Asthma and Immunology. “I am excited to see what’s possible with this innovative treatment in 4-7-year-old patients, if approved. I look forward to open-label results in the future to fully understand the potential impact VIASKIN Peanut can have in this age group.”
DBV is moving forward with plans for a Biologics License Application (BLA) submission in the United States in the first half of 2026.
“VITESSE is the largest immunotherapy clinical trial ever conducted in food allergy and we are thrilled that the resulting clinical evidence supporting the VIASKIN Peanut patch is robust. With these data in hand, I am looking forward to submitting the BLA to the FDA, as planned, in the first half of 2026,” stated Daniel Tassé, Chief Executive Officer of DBV Technologies. “I would again like to express my gratitude to the FDA for a constructive dialogue that enabled us to reach alignment on a path forward for this important program, as well as our clinical investigators and their staff. Most importantly, we must acknowledge the tremendous belief, dedication, and investment made by patients and all those who participated in the study—without whom the efficient execution of the study would not have been possible. Thanks to the food allergy community, we are one step closer to delivering on our mission to transform the lives of children and families living with peanut allergy.”
The FDA previously granted Breakthrough Therapy Designation for VIASKIN Peanut patch, and the Company expects the BLA may be eligible for priority review.

About DBV Technologies
DBV Technologies is a late-stage biopharmaceutical company developing treatment options for food allergies and other immunologic conditions with significant unmet medical need. DBV is currently focused on investigating the use of its proprietary VIASKIN® patch technology to address food allergies, which are caused by a hypersensitive immune reaction and characterized by a range of symptoms varying in severity from mild to life-threatening anaphylaxis. Millions of people live with food allergies, including young children. Through epicutaneous immunotherapy (EPIT), the VIASKIN® patch is designed to introduce microgram amounts of a biologically active compound to the immune system through intact skin. EPIT is a new class of non-invasive treatment that seeks to modify an individual’s underlying allergy by re-educating the immune system to become desensitized to allergen by leveraging the skin’s immune tolerizing properties. DBV is committed to transforming the care of food allergic people. The Company’s food allergy programs include ongoing clinical trials of VIASKIN® Peanut in peanut allergic toddlers (1 through 3 years of age) and children (4 through 7 years of age).
DBV Technologies is headquartered in Châtillon, France, with North American operations in Warren, NJ. The Company’s ordinary shares are traded on segment B of Euronext Paris (Ticker: DBV, ISIN code: FR0010417345) and the Company’s ADSs (each representing five ordinary shares) are traded on the Nasdaq Capital Market (Ticker: DBVT; CUSIP: 23306J309).

About the VITESSE Study
VITESSE (NCT05741476) is a global Phase 3, randomized, double-blind, placebo-controlled clinical trial evaluating the efficacy and safety of the VIASKIN Peanut patch 250 µg in children ages 4-7 years with peanut allergy. The study enrolled 654 children randomized 2:1 to receive either VIASKIN Peanut patch or placebo. Conducted at 86 sites across the United States, Canada, United Kingdom, Europe, and Australia, VITESSE represents the largest immunotherapy clinical trial for this patient population. The primary endpoint is the difference between the percentage of treatment responders in the active versus placebo group after 12 months of treatment. Following the 12-month double-blind period, children were given the option to continue into an open-label extension where all participants receive VIASKIN Peanut patch for up to a total of three years on treatment.
DBV plans to present the full VITESSE results at future medical congresses as well as submit them for publication in a peer-reviewed journal.
