Significant Events And Transactions of the Period Disclsure [Abstract] | |
Significant Events and Transactions | Note 2: Significant Events and Transactions Clinical programs United States Regulatory History and Current Status In January 2021, the Company received written responses from the FDA to questions provided in the Type A meeting request the Company submitted in October 2020 following the Complete Response Letter. The FDA agreed with its position that a modified Viaskin Peanut patch should not be considered as a new product entity provided the occlusion chamber of the current Viaskin Peanut patch and the peanut protein dose of 250 µg (approximately 1/1000 of one peanut) remains unchanged and performs in the same way it has performed previously. In order to confirm the consistency of efficacy data between the existing and a modified patch, FDA requested an assessment comparing the uptake of allergen (peanut protein) between the patches in peanut allergic children ages 4-11. The Company named that assessment EQUAL, which stands for Equivalence in Uptake of ALlergen. The FDA also recommended conducting a 6-month, well-controlled safety and adhesion trial to assess a modified Viaskin Peanut patch in the intended patient population. The Company later named this study STAMP, which stands for Safety, Tolerability, and Adhesion of Modified Patches. Based on the January 2021 FDA feedback, the Company defined three parallel workstreams: 1. Identify a modified Viaskin patch (which the Company calls “mVP”). 2. Generate the 6-month 3. Demonstrate the equivalence in allergen uptake between the current and modified patches in the intended patient population via EQUAL. The complexity of EQUAL hinged on the lack of established clinical and regulatory criteria to characterize allergen uptake via an epicutaneous patch. To support those exchanges, the Company outlined its proposed approach to demonstrate allergen uptake equivalence between the two patches, and allotted time to generate informative data through two additional Phase 1 clinical trials in healthy adult volunteers: a. PREQUAL, a Phase 1 study with adult healthy volunteers to optimize the allergen sample collection methodologies and validate the assays we intend to use in EQUAL. The data collection phase of the trial is complete, and the data analysis phase is ongoing. b. ‘EQUAL in adults’—a second Phase 1 trial with adult healthy volunteers to compare the allergen uptake of cVP and mVP; In March 2021, the Company commenced CHAMP (Comparison of adHesion Among Modified Patches), a Phase 1 trial in healthy adult volunteers to evaluate the adhesion of five modified Viaskin Peanut patches. The Company completed CHAMP in the second quarter of 2021. All modified Viaskin Peanut patches demonstrated better adhesion performance as compared to the then-current Viaskin Peanut patch, and the Company then selected two modified patches that performed best out of the five modified patches studied for further development. The Company then selected the circular patch for further development, which is larger in size relative to the current patch and circular in shape. In May 2021, the Company submitted its proposed STAMP protocol to the FDA, and on October 14, 2021, the Company received an Advice/Information Request letter from the FDA. In this letter, the FDA requested a stepwise approach to the modified Viaskin patch development program and provided partial feedback on the STAMP protocol. Specifically, the FDA requested that the Company conduct allergen uptake comparison studies (i.e., ‘EQUAL in Adults’, EQUAL), and submit the allergen uptake comparison data for FDA review and feedback prior to starting the STAMP study. The FDA’s explanation was that the results from the allergen uptake studies might affect the design of the STAMP study. After careful review of the FDA’s information requests, in December 2021, the Company decided not to pursue the sequential approach to the development plans for Viaskin Peanut as requested by the FDA in the October 2021 feedback. The Company estimated that the FDA’s newly proposed sequential approach would require at least five rounds of exchanges that necessitate FDA alignment prior to initiating STAMP, the 6-month In 2022, the Company announced the new Phase 3 pivotal study for modified Viaskin Peanut (mvP) patch would be in younger (4-7 On September 7, 2022, the Company announced the initiation of VITESSE, a new Phase 3 pivotal study of the modified Viaskin Peanut (mVP) patch in children ages 4-7 On September 21, 2022, the Company announced it received feedback from the U.S. FDA in the form of a partial clinical hold on VITESSE . In the partial clinical hold letter, the FDA specified changes to elements of the VITESSE protocol, acknowledging the intent for the trial to support a future BLA submission. In the following months, we engaged with the FDA to address the feedback provided in the partial clinical hold letter and to finalize the VITESSE protocol. In addition, we continued internal preparations for VITESSE and conducted certain site assessment and start-up On December 23, 2022, the Company announced the FDA lifted the partial clinical hold and confirmed we satisfactorily addressed all clinical hold issues. The FDA stated that VITESSE may proceed with the revised trial protocol. On March 2, 2023, the Company announced the completion of EVOLVE, a 12-week caregiver and patient user experience study of the mVP patch in 50 peanut allergic children ages 4–11-years old. The objective of EVOLVE was to evaluate the Instructions for Use (IFU) and ease of use for the mVP patch. The study concluded that the updated IFU supported correct patch application, which included no lifting of the patch edges or detachment directly after application. Furthermore, EVOLVE concluded that the majority of parents/caregivers reported a positive ease of use experience with the mVP patch. In EVOLVE, DBV also tested the functionality of an electronic patient diary (eDiary) to collect information on activities of daily living and patch adhesion scores. EVOLVE verified that the eDiary tool can be used by caregivers in VITESSE to capture the adhesion data in support of a potential BLA. On March 7, 2023, the Company announced that the first patient was screened in the VITESSE study. Screening of the last patient is anticipated in the first half in 2024 and topline results in the first half in 2025. European Union Regulatory History and Current Status On August 2, 2021, the Company announced its received from the European Medicines Agency (EMA) of the Day 180 list of outstanding issues, which is an established part of the prescribed EMA review process. It is a letter that is meant to include any remaining questions or objections at that stage in the process. The EMA indicated many of their objections and major objections from the Day 120 list of questions had been answered. One major objection remained at Day 180. The Major Objection questioned the limitations of the data, for example, the clinical relevance and effect size supported by a single pivotal study. On December 20, 2021, the Company announced it had withdrawn the Marketing Authorization Application (MAA) for Viaskin Peanut and formally notified the EMA of our decision. The initial filing was supported data from a single, placebo-controlled Phase 3 pivotal trial known as PEPITES (V712-301). Viaskin Peanut for children ages 1-3 In June 2020, the Company announced that in Part A, patients in both treatment arms showed consistent treatment effects after 12 months of therapy, as assessed by a double-blind placebo-controlled food challenge and biomarker results. Part A subjects were not included in Part B and the efficacy analyses from Part A were not statistically powered to demonstrate superiority of either dose versus placebo. These results validate the ongoing investigation of the 250 µg dose in this age group, which is the dose being studied in Part B of the study. Enrollment for Part B of EPITOPE was completed in the first quarter of 2021. In June 2022, the Company announced positive topline results from Part B of EPITOPE, which enrolled 362 subjects ages 1 to 3 years, of which 244 and 118 were in the active and placebo arms respectively. Enrollment was balance for age and baseline disease characteristics between the active and placebo treatment arms. On April 19, 2023, the Company announced the FDA provided written responses regarding the regulatory path for Viaskin Peanut in toddlers ages 1-3 years old with a confirmed peanut allergy. In February 2023 the Company submitted a pre-BLA Meeting request to FDA and the Agency granted DBV’s request as a written response only. In the written responses received, the Agency confirmed that the Company’s Phase 3 EPITOPE study met the pre-specified criteria for success for the primary endpoint. The FDA did not request an additional efficacy study to support a future BLA but requires that DBV conduct an additional safety study in 1 – 3-year-olds using the original Viaskin Peanut patch to augment the safety data collected from the Phase 3 EPITOPE study. The new safety study is intended to bring the safety database in 1–3-year-olds close to 600 patients on active treatment which is consistent with FDA’s position in support of the Company’s dossier in 4–7-year-olds. The safety study will not require a food challenge for study participation, will generate patch adhesion data, and will include updated instructions for use. Viaskin Peanut for Children ages 4-7 On September 7, 2022, the Company announced the initiation of VITESSE, a new Phase 3 pivotal study of the modified Viaskin Peanut (mVP) patch in children ages 4-7 years with peanut allergy. We defined initiation as the submission of the trial protocol to selected study sites for subsequent Institutional Review Board (IRB)/Ethics Committee (EC) approval. On September 21, 2022, the Company announced we had received feedback from the FDA in the form of a partial clinical hold on VITESSE. In the partial clinical hold letter, the FDA specified changes to elements of the VITESSE protocol, acknowledging the intent for the trial to support a future BLA submission. In the following months, we engaged with the FDA to address the feedback provided in the partial clinical hold letter and to finalize the VITESSE protocol. In addition, we continued internal preparations for VITESSE and conducted certain site assessment and start-up activities for prompt study launch once the partial clinical hold was lifted. On December 23, 2022, the Company announced the FDA lifted the partial clinical hold and confirmed we satisfactorily addressed all clinical hold issues. The FDA stated that VITESSE may proceed with the revised trial protocol. On March 7, 2023, the Company announced that the first patient was screened in the VITESSE trial. Screening of the last patient is anticipated in the first half in 2024 and topline results in the first half in 2025. Legal Proceedings From time to time, the Company may become subject to various legal proceedings and claims that arise in the ordinary course of our business activities. The Company is not currently subject to any material legal proceedings. |

Earnings Per Share [Abstract] | |
Loss Per Share | Note 14: Loss Per Share Basic loss per share is calculated by dividing the net loss attributable to the shareholders of the Company by the weighted average number of ordinary shares outstanding during the period. As the Company was in a loss position for each of the three months ended March 31, 2023 and 2022, the diluted loss per share is equal to basic loss per share because the effects of potentially dilutive shares were anti-dilutive as a result of the Company’s net loss. The following is a summary of the ordinary share equivalents that were excluded from the calculation of diluted net loss per share for each of the three months ended March 31, 2023 and 2022 indicated in number of potential shares: Three Months Ended 2023 2022 Non-employee 251,693 256,693 Stock options 5,318,569 3,471,808 Restricted stock units 1,583,938 1,183,633 Prefunded warrants 28,276,331 — |

Basis of Presentation | Basis of Presentation The condensed consolidated financial statements of the Company and its wholly-owned subsidiaries are unaudited and have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) and are presented in U.S. dollars. All significant intercompany accounts and transactions between the Company and its subsidiaries have been eliminated on consolidation. The unaudited condensed consolidated financial statements presented in this Quarterly Report should be read in conjunction with the consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted from these interim financial statements. However, these condensed consolidated financial statements include all adjustments, consisting only of normal recurring adjustments, which are, in the opinion of management, necessary to fairly state the results of the interim period. These interim financial results are not necessarily indicative of results to be expected for the full fiscal year ending December 31, 2023, or any other future period. |
Use of estimates | Use of estimates The preparation of the Company’s condensed consolidated financial statements requires the use of estimates, assumptions and judgments that affect the reported amounts of assets, liabilities, and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amount of income and expenses during the period. The Company bases its estimates and assumptions on historical experience and other factors that it believes to be reasonable under the circumstances. The Company evaluates its estimates and assumptions on an ongoing basis. The actual results may differ from these estimates. On an on-going right-of-use |
