Thank you, Daniel. Let's start with a brief recap of Viaskin Peanut program in toddlers ages 1 to 3 which you will recall, uses the original square Viaskin Peanut patch. We already completed our pre-BLA meeting for toddlers in April of this year. As we previously announced, the agency confirmed that our Phase III EPITOPE study met the prespecified criteria for success for the primary endpoint and therefore, did not request an additional efficacy study. The FDA did ask for a supplemental safety study with the original square patch to increase the total number of subjects on active treatment to approximately 600 per regulatory guidelines. The FDA did not raise any specific safety concerns associated with this request. The 4-year to 7-year-old indication will also have a supplemental safety study to increase the number of subjects on treatment with the modified circular patch to approximately 600 subjects, when combined with the active subjects in the test, the ongoing Phase III efficacy and safety study. So we believe there is nice symmetry to the 2 BLA programs. The 1-year to 3-year-old indication has a completed efficacy and safety study in EPITOPE and a planned supplemental safety study in COMFORT Toddlers. We believe that this will constitute the pivotal studies needed for a BLA submission. Similarly, the 4-year to 7-year-old indication will have the test for efficacy and safety in COMFORT Children for supplemental safety. We've discussed the key design elements of both supplemental safety studies in the past. But just to remind you, both studies will be 6 months in duration, double-blind, placebo-controlled, 3:1 randomization active to placebo and both will generate adhesion data. COMFORT Toddlers will include 400 subjects and COMFORT Children will be 270 subjects in total. These numbers have not changed. Okay. So that brings us to today. After receiving the Type C meeting feedback on the safety studies in July, we requested clarification from the FDA. There were a few remaining protocol design elements relevant to both safety studies as well as 1 of the inclusion criterion just for COMFORT Toddler that we felt needed additional clarity. I'm pleased to report that we have received written feedback from the FDA, clarifying those remaining protocol design elements. The protocols for both supplemental safety studies will have the same language guiding how the product should be used such as, each DBV712 250-microgram epi-cutaneous system is intended to be worn for a full day 24 hours. We believe that this language is more concise and simpler and harmonizing the language in both safety studies makes a lot of sense. Further to this approach, both supplemental safety studies will seek to enroll subjects that are as closely aligned with their respective Phase III efficacy studies as is feasible. For COMFORT Toddlers, this means using the same eligibility criteria as in the EPITOPE study. In EPITOPE, the main inclusion criteria centered around a documented history of peanut allergy, confirmed by immunologic markers, IgE and skin prick testing and a double-blind placebo-controlled food challenge. We previously believed that no food challenge would be required for COMFORT Toddlers but in exchanges with the FDA, we chose these inclusion criteria options as the best way to ensure that we could recruit a study population that would be as similar to EPITOPE as possible. While there is a significant body of immunological literature in older peanut-allergic children, the same is just not true in the toddler range. Because of this, we felt that reliance on immunological parameters alone for the main inclusion criteria did not provide the same level of assurance as the EPITOPE eligibility criteria. However, for COMFORT Children, we will use a history of peanut allergy and immunologic parameters for the inclusion criteria. The medical literature supports this approach, as does our experience in the completed 4 to 11-year-old safety study REALISE which served as a supplemental safety study for PEPITES. With this approach, we are confident that we can enroll a study population that will be similar to that of the test. There will not be a need for a confirmatory double-blind, placebo-controlled food challenge for COMFORT Children. Since EPITOPE was a successful study, meeting the prespecified criteria for success for the primary endpoint and we have received regulatory guidance from FDA, COMFORT Toddlers is our highest priority to get started as quickly as possible. Now that we have received clarification, we can submit the safety protocol to the FDA expeditiously and anticipate enrollment to begin in the first quarter of 2024. In parallel, the COMFORT Children protocol will be finalized and submitted to the FDA. Since it is a smaller study relative to COMFORT Toddlers and we don't wish to compete with the test recruitment at this time, we plan to initiate enrollment in COMFORT Children after COMFORT Toddlers. We are continuing to work diligently on appropriate study start-up activities for both COMFORT studies, while in parallel, continuing to advance the test, our Phase III study in 4-year to 7-year olds. To summarize, we are very pleased with the engagement and clarity of the feedback received from the FDA. We feel that harmonizing the approach to how the product should be used is even simpler and more concise than what previously existed. We are confident we can enroll subjects in our supplemental safety studies that will align nicely with the respected efficacy studies and we remain confident that this work will support BLAs in both age groups and potentially bring a new treatment option to clinicians and families. At this point, I'll turn the call back over to Daniel to review the financial results. Daniel?
Daniel Tassé: Thank you, Pharis. And now let's briefly review the financial highlights for Q3 2023. Our cash and cash equivalents as of September 30 are $149.1 million compared to -- sorry, $209.2 million as of December 31, 2022, a net decrease of $60.1 million, mainly due to the following: $66 million of cash was used in operating activities, mainly driven by clinical work and initiation of the VITESSE trial where the first patient was screened in March of this year. And then $7 million of net proceeds on the issuance and sale of new ordinary shares in the form of ADS' which took place on June 16, 2023, pursuant to the company's at-the-market program which was established in May of 2022. You can see we continue to maximize the efficiency of our spend. We remain highly committed and disciplined in our cash management. We have a lot of clinical work to do by next year. We anticipate we'll have about 1,400 patients or subjects enrolled in Viaskin Peanut Phase III studies. So we've covered a lot today and if you allow me to recap. Pharis' team is working diligently to implement the feedback we requested from the FDA into the COMFORT safety study protocols for submission to the agency. We expect to submit the finalized COMFORT Toddlers protocol in the next few weeks, anticipate initiating the COMFORT Toddlers study in the first quarter of 2024. We believe that the successful completion of the supplemental COMFORT Toddlers safety study would be an important step towards filing a BLA seeking marketing approval in the U.S. of this potential novel therapy for peanut allergenic toddlers and their families. As Pharis mentioned, initiation of COMFORT Children is expected after the start of COMFORT Toddlers and in close alignment with VITESSE recruitment. And we are continuing to advance VITESSE, successful completion of which will be an important step towards filing a separate BLA seeking marketing approval in the U.S. for this potential novel therapy in peanut allergic children aged 4 to 7. I want to thank everyone on the phone and on the webcast for joining us today. And I will now ask Pharis to join me for Q&A. Operator, if you can open the line, please?
