be worn for a full day (24 hours).” These instructions are simpler and more concise relative to previously used protocol language.
Further to this approach, both supplemental safety studies will seek to enroll populations that are closely aligned with their respective Phase 3 efficacy studies, as is feasible. For COMFORT Toddlers, eligibility criteria will be the same as in EPITOPE (Phase 3 efficacy study in 1-3-year-olds) as reliance on peanut specific-IgE and skin prick test alone does not ensure a Regulatory-level of assurance of peanut allergy or a similar peanut allergic patient population relative to EPITOPE. Thus, COMFORT Toddlers will include a double-blind, placebo-controlled food challenge (DBPCFC) as part of the Inclusion criteria.
For COMFORT Children, key inclusion criteria will remain peanut specific-IgE and skin prick test as these criteria are well established from previously conducted DBV studies (PEPITES and REALISE), as well as from the medical literature, and are expected to support enrollment of a similar study population relative to VITESSE (Phase 3 efficacy study in 4-7-year-olds). Therefore, a DBPCFC will not be required for COMFORT Children.
The size and duration of both supplemental safety studies remains unchanged from previous communications. These protocol design elements ensure closer alignment between the supplemental safety studies and their respective efficacy studies, which should ultimately support a more robust future BLA submission package for each indication.
“We are very pleased with the engagement and clarity of the feedback received from the FDA,” stated Pharis Mohideen, Chief Medical Officer of DBV Technologies. “With a clear regulatory path forward, we will submit to FDA the final protocols for the COMFORT studies. We remain confident that this work will support a Biologics License Application (BLA) in both age groups and potentially bring this novel, much needed therapy to a vulnerable patient population.”
DBV will implement the FDA’s feedback and expects to submit the final COMFORT Toddlers protocol design to the Agency in the coming weeks. DBV anticipates the first subject will be enrolled in Q1 2024. The initiation of COMFORT Children is expected after the start of COMFORT Toddlers and in alignment with VITESSE recruitment.
