• First patient screened at Midwest Allergy Sinus Asthma in Normal, Illinois
• VITESSE is DBV’s Phase 3 clinical study evaluating the modified Viaskin Peanut patch in peanut-allergic children ages 4 – 7 years

DBV Technologies (Euronext: DBV – ISIN: FR0010417345 – Nasdaq Market: DBVT), a clinical-stage biopharmaceutical company, today announced that the first patient has been screened in the Company’s VITESSE (Viaskin Peanut Immunotherapy Trial to Evaluate Safety Simplicity and Efficacy) Phase 3 clinical trial that will evaluate the modified Viaskin™ Peanut 250 μg patch (DBV712) in peanut-allergic children ages 4 through 7 years.

Viaskin Peanut 250 μg is a novel treatment designed to re-educate the immune system by introducing microgram amounts of peanut allergen to the immune system through intact skin. The VITESSE trial will use the modified Viaskin Peanut 250 μg patch and enroll 600 subjects, randomized 2:1 active versus placebo. The study will involve approximately 80 trial sites across the United States, Canada, Australia, and Europe. The primary efficacy endpoint of the study is the percentage of treatment responders in the active versus placebo arms at Month 12. Secondary efficacy endpoints include changes in cumulative reactive dose (CRD), eliciting dose (ED) and severity of allergic reaction at Month 12 food challenge.

“I am pleased that the first trial participant has been screened in the VITESSE study,” said David Fleischer, MD, FAAAAI, FACAAI, Children’s Hospital Colorado and Global Principal Investigator for the VITESSE study, “These peanut-allergic children represent a cohort of patients that are eagerly awaiting potential treatment options. I am looking forward to leading the team of highly skilled VITESSE investigators and their staff as we generate these critical data that may one day potentially support a BLA submission for Viaskin Peanut.”

Last year, following productive exchanges with the U.S. Food and Drug Administration (FDA), DBV finalized the VITESSE protocol and received the FDA’s support to advance the study. Previously, the FDA had requested changes to certain elements of the VITESSE protocol with the intent for the trial to support a future Biologics License Application (BLA).

"The initiation of the VITESSE Phase 3 Study in peanut-allergic children ages 4 - 7 years represents a culmination of years of research and collaboration between DBV, FDA, patient groups, site investigators, trial centers, and, of course, the support and unwavering encouragement from food-allergic families,” said Pharis Mohideen, MD, Chief Medical Officer, DBV Technologies. “DBV is proud to see that patient screening has begun in Q1 2023. This important milestone reflects incredible work from the DBV team and swift action in beginning enrollment from Principal Investigators like Dr. Dareen Siri and others. We are grateful for the strong collaboration that will continue throughout the VITESSE study.”

Principal Investigator, Dr. Dareen Siri, FAAAAI, FACAAI from Midwest Allergy Sinus Asthma, in Normal and Springfield, Illinois was the first to conduct a screening visit for a potential new enrollee.

"I am thrilled that our talented team of clinicians was the first to screen a patient for the VITESSE clinical study,” said Dareen Siri, MD, Midwest Allergy Sinus Asthma, Normal, IL. “The initiation of patient enrollment in VITESSE reinforces our commitment to peanut-allergic children and their families and is an important step in generating the data needed to potentially advance Viaskin Peanut to market. I am grateful that peanut-allergic children have the opportunity to participate in a trial that may one day help other kids just like them living with peanut allergy. There is a lot of excitement around the VITESSE study, and I am proud our team will be an integral part of it.”

DBV anticipates screening the last patient in 1H 2024 and announcing topline results in 1H 2025.

About VITESSE

The VITESSE trial will enroll 600 subjects, randomized 2:1 active versus placebo. The study will involve approximately 80 trial sites across the United States, Canada, Australia and Europe. Dr. David Fleischer, Colorado Children’s Hospital, will act as the global study Principal Investigator.

The primary efficacy endpoint is the percentage of treatment responders in the active versus placebo arms at Month 12. The primary efficacy analysis includes the success criterion of a lower bound of the confidence interval of the difference in responder rates between active and placebo groups being greater than or equal to 15%.

A treatment responder is defined as either a subject with a baseline ED ≤30 mg who reaches an ED ≥300 mg of peanut protein at Month 12, or a subject with a baseline ED = 100 mg who reaches an ED ≥600 mg of peanut protein at Month 12. A double-blind, placebo-controlled food challenge (DBPCFC) will be administered at baseline and Month 12 to determine a subject’s ED at both timepoints.

During the screening period, subjects will undergo an initial visit with assessment for eligibility according to peanut skin prick test (SPT) and serum peanut IgE. Those meeting these criteria will proceed to a DBPCFC to confirm their peanut allergy and establish an entry peanut ED. The entry DBPCFC will be 1 mg peanut protein, and will escalate up to a highest single dose of 100 mg peanut protein. Subjects who react with an ED at or below the dose of 100 mg peanut protein and meet all other inclusion and no exclusion criteria are considered eligible. At Month 12, a post-treatment DBPCFC will be performed, with a starting dose of 3 mg peanut protein, escalating to a highest dose of 1,000 mg peanut protein according to the following schedule: 3, 10, 30, 100, 300, 600, 1,000 mg. Secondary efficacy endpoints include changes in CRD, ED and severity of allergic reaction at Month 12 food challenge.
