DBV Technologies Hits Major Milestone With Peanut Allergy Patch Trial Results

DBV Technologies' experimental peanut allergy patch showed significant results in a pivotal Phase 3 trial, with nearly half of treated children responding to therapy. The company plans to file for FDA approval in 2026.

DBV Technologies S.A. (DBVT) just delivered the kind of clinical trial results that make allergists and parents sit up and take notice. The company announced Tuesday that its VIASKIN Peanut patch met the primary endpoint in a pivotal Phase 3 study, bringing a potentially transformative treatment for childhood peanut allergies one step closer to market.

The Numbers That Matter

Here's what happened in the VITESSE trial: After 12 months of treatment, 46.6% of children wearing the active VIASKIN Peanut patch became treatment responders, compared to just 14.8% in the placebo group. That's a statistically significant difference, which is exactly what regulators want to see.

But what does "responder" actually mean? The trial defined responders as children who could tolerate substantially more peanut protein after treatment. Specifically, kids who started with a baseline eliciting dose of 30 mg or less had to achieve tolerance of at least 300 mg of peanut protein. For those starting at 100 mg, the bar was set at 600 mg. These thresholds were measured using double-blind, placebo-controlled food challenges, the gold standard for allergy testing.

The eliciting dose, for context, is the amount of peanut protein that triggers an allergic reaction. Moving from 30 mg to 300 mg represents a tenfold increase in tolerance, potentially the difference between accidental cross-contamination being life-threatening versus manageable.

Trial Design and Safety Profile

VITESSE enrolled 654 peanut-allergic children aged 4 to 7 years, actually exceeding the original enrollment target of 600. The trial randomized 438 children to the active treatment arm and 216 to placebo.

The safety data looks encouraging. The most common side effects were mild-to-moderate local skin reactions at the patch application site, which makes sense given the mechanism of action. Discontinuation rates due to adverse events were low at 3.2% in the treatment group versus 0.5% in placebo.

More importantly, there were no treatment-related serious adverse events. Treatment-related anaphylaxis occurred in just 0.5% of patients (two children), and both continued treatment afterward. Patient compliance was high at 96.2%, consistent with other Phase 3 VIASKIN Peanut studies. The company also noted that exploratory adhesion assessments aligned with expectations, addressing a practical concern about whether kids would actually keep the patches on.

The Path to FDA Approval

DBV Technologies is now moving forward with plans to submit a Biologics License Application in the United States during the first half of 2026. This represents a significant milestone for the company, which has been developing epicutaneous immunotherapy (that's the fancy term for delivering treatment through the skin) for food allergies.

The market certainly liked what it heard. DBVT shares surged 35.76% to $24.41 during premarket trading on Tuesday, hitting a new 52-week high. For a biotech company that's been working toward this moment for years, positive Phase 3 data is the kind of catalyst that can transform valuations overnight.
