Thank you, John. Recently in July, we were very pleased to have FDA grant cytisinicline breakthrough therapy designation for the vaping cessation indication. Breakthrough therapy designation is important because, it offers access to an FDA cross-disciplinary project management team for interactive communications with senior managers and reviewers at FDA. This will be beneficial in completing the regulatory requirements necessary for expanding cytisinicline treatment, as the first approved pharmacotherapy in treating nicotine dependence for e-cigarettes cessation, not only in adults, but also possibly for an adolescent vaping population. The public heightened issues surrounding the increasing e-cigarette use in young adults and adolescents justifies the need for urgent action towards a solution. Breakthrough therapy designation, will help to accelerate our proposed clinical program with more active FDA input. Although there is a general understanding that using e-cigarettes is safer, alternative to smoking, combustible cigarettes. This has led to the perception that e-cigarettes or vaping nicotine is safe. Resulting in a new, younger generation becoming addicted to nicotine. The developing body of scientific and medical evidence is now showing that long-term e-cigarette use can be harmful, and may lead to more severe addiction, due to the high nicotine levels in vapes. Long-term e-cigarette use may also contribute to potential lung injury, asthma, COPD and negative cardiovascular effects. At the annual March meeting of the Society for Research on Nicotine and Tobacco, guidance from experts in the field was presented based on Project VECTOR, which stands for Vaping and Electronic Cigarette Toxicity Overview and Recommendations. Several recommendations were presented, which included, people who do not smoke should not use nicotine e-cigarettes, and people who use e-cigarettes should avoid long-term use of e-cigarettes. These recommendations were based on reducing long-term respiratory injury, adverse effects on the cardiovascular system and exposure to cancer-causing chemicals in vaping aerosols, as well as preventing sustained nicotine dependence. Breakthrough therapy was developed to expedite the clinical development of products that treat serious conditions, which there is an unmet need, and when there is preliminary evidence demonstrating potential benefit. Our justification was that long-term vaping may lead to serious conditions, that there are no approved treatments to assist people in quitting and that the positive results we observed in our ORCA-V1 trial, showed the potential benefit of cytisinicline in this setting. These criteria were all instrumental in granting us breakthrough status. We've already submitted a request for a Type-B meeting with FDA that will start interactions with their cross-disciplinary project management team, and will also serve as an end of Phase 2 meeting for gaining agreement on the development plans for Vaping Cessation Indication. Moving on to our Lead Indication Smoking Cessation and the status of the long-term cytisinicline exposure trial. In May, we initiated the open-label ORCA-OL trial, which is collecting long-term exposure data on cytisinicline. ORCA-OL is recruiting subjects for -- who participated in our previous Phase 2 and Phase 3 trials. We are pleased to report that all 29 clinical sites are actively enrolling subjects. Enrollment has been going very well and more than half of the proposed 650 participants have already been enrolled onto the study. Over the next few months, we will be monitoring the treatment discontinuation rate which is currently very low. The enrollment objective, is to ensure that we achieve the required 300 subjects exposed for six months at NDA submission, providing that subject retention rates continue to remain high. We anticipate possibly closing out enrollment in advance of the 650 enrollment cap, possibly within the next two months. As a reminder, the primary analysis for this study will be to evaluate the rate of serious adverse events thought to be related to cytisinicline treatment. And we have engaged the same independent Data Safety Monitoring Committee who had oversight of Orca 2, Orca 3 and ORCA-V1 studies to, oversee and review safety events during this open-label study. We plan to provide general summary updates following the completion of these committees safety reviews with the first meeting expected to occur in the fourth quarter, and subsequent meetings to be determined by the committee members thereafter. Based on our agreement with FDA, the necessary clinical data from ORCA-OL remains on track to support an NDA submission during the first half of 2025. As we continue our monitoring of subjects being treated in the open-label study and their exposure timing, we can further refine our guidance in the future on the NDA submission timing. Overall, I'm very pleased with the rapid progress we have made both in the clinic and with regulators, since our last update. I'll now turn it back over to John.
