DBV Technologies Announces Results from Phase II Study of Viaskin Milk in Milk-Allergic Patients

Positive preliminary results support Viaskin Milk's potential as the first treatment for patients suffering from IgE-mediated cow's milk protein allergy (CMPA), an unmet medical need for which there are no approved therapies  

A statistically significant desensitization to milk was observed in children ages two to 11 treated with Viaskin Milk 300 µg for 12 months

Company evaluating optimal dosing/patient population for future studies

DBV Technologies (Euronext: DBV - ISIN: FR0010417345 - Nasdaq Stock Market: DBVT) today announced preliminary results from Part B, or Phase II, of a Phase I/II study evaluating the efficacy and safety of three dose regimens of Viaskin Milk (150 µg, 300 µg, 500 µg) in 198 patients for the treatment of IgE-mediated cow's milk protein allergy (CMPA). The MILES (Milk Efficacy and Safety) study was designed to determine a safe and effective dose in two age groups: children ages two to 11 and adolescents ages 12 to 17.

Following analyses of the data, the 300 µg dose was identified as the most effective tested dose for children (intent-to-treat (ITT), p=0.042). The Company believes these preliminary results support further advancement of the Viaskin Milk program, and intends to discuss findings with health authorities in key markets worldwide to determine the design of future studies. Viaskin Milk was granted U.S. Food and Drug Administration (FDA) Fast Track Designation in September 2016.

"This is an important milestone for the millions of patients suffering from CMPA worldwide. We know that small amounts of cow's milk protein can cause life-threatening reactions, and that this disease has a profoundly negative impact on the quality of life of patients and their caregivers," said Dr. Stephen A. Tilles, Executive Director, ASTHMA Inc. Clinical Research Center, Physician Partner at Northwest Allergy & Asthma Center (NAAC), and the Principal Investigator of the MILES trial. "There are no other treatments in development today for this hard-to-treat disease, and it is exciting to see these encouraging efficacy and safety results with a novel potential treatment option that appears to be well-tolerated.

The primary efficacy endpoint of the study evaluated the percentage of patients who responded to treatment as assessed by pre-specified changes from baseline in double-blind-placebo-controlled food challenge (DBPCFC) cumulative reactive doses after 12 months of treatment1. Key secondary endpoints evaluated mean and median cumulative reactive dose (CRD) during the month-12 DBPCFC.
The overall patient population treated according to the protocol (per-protocol analysis population) was also scientifically relevant for this dose-finding study, and the response rate in the 300 µg dose showed a significant improvement versus placebo (p=0.027), which was consistent with ITT statistical trends.

Highlights of the MILES Study

Analysis of the data showed a statistically significant response in the 300 µg arm in the 2-11 age group (ITT, p=0.042), which was identified as the prioritized population for future studies.         

A significant increase in CRD versus baseline as measured by changes in the month-12 DBPCFC was observed in children treated with the 300 µg dose as compared to placebo (ITT, p=0.045). 

Viaskin Milk was reported to be well tolerated across all doses with no treatment-related serious adverse events (SAEs). The most commonly reported adverse events were mild and moderate application site reactions. Overall, the discontinuation rate was 4.5%, with a 1.5% dropout rate due to adverse events. Treatment adherence, as measured by mean patient compliance, was over 95% in all study groups.

Dr. Hugh Sampson, Chief Scientific Officer of DBV Technologies and Kurt Hirschhorn Professor of Pediatrics at the Icahn School of Medicine at Mount Sinai said, "We would like to thank all of the patients, caregivers and investigators who participated in this trial with Viaskin Milk, our second Viaskin platform product candidate in food allergies. These studies brought new insight into our understanding of Viaskin Milk's unique immunotherapeutic properties and mechanism of action. We will continue working to better understand the appropriate dose regimens and optimal application protocols." Dr Sampson continued, "We look forward to discussing next steps with health authorities to move this important program forward, and to most importantly, bringing a potential treatment option to this underserved patient population."

Overall, 98.9% of patients completing month-12 of MILES opted to enroll in the open-label portion of the study and are currently being treated with Viaskin Milk 500 µg for up to 48 months. The Company will assess next steps on any potential protocol changes with regulatory authorities. Additional results from MILES are expected to be presented at upcoming medical meetings.

About the MILES Study

The Viaskin Milk Efficacy and Safety (MILES) trial is a multi-center, double-blind, placebo-controlled, randomized Phase I/II trial to study the safety and efficacy of Viaskin Milk conducted at 17 sites in North America. The study was divided into two consecutive parts. Part A of the MILES trial was completed with no safety concerns. Part B was designed to determine a safe and effective dose in two age groups: children ages two to 11 and adolescents ages 12 to 17 with IgE-mediated cow's milk protein allergy, or CMPA.

198 patients (18 patients from Part A and 180 patients from Part B) were randomized 1:1:1:1 into four treatment arms to evaluate three doses of Viaskin Milk, 150 mcg, 300 mcg and 500 mcg, compared to placebo. Each patient underwent a DBPCFC at screening and after 12 months of treatment. The challenge was halted once the patient exhibited an objective allergic symptom. Patients in MILES received a daily application of the Viaskin Milk patch over 12 months. Each patch was applied for 24 hours on the back of children (age 2- 11) or on the upper arm for adolescents (age 12-17).

The primary efficacy endpoint was the percentage of treatment responders for each active treatment group compared to placebo. Responders at month-12 were defined as patients with either 1) a cow's milk protein CRD equal to or greater than 1,444 mg (approximately 45 mL of milk) or 2) a 10-fold or greater increase in CRD compared to baseline and at least 144 mg cow's milk protein (approximately 4.5 mL of milk).

Following month-12 all subjects were eligible to switch to the highest dose of Viaskin Milk, 500 mcg, and to continue treatment in an open-label manner for up to a maximum of three additional years.
