Thank you, Jaime. On today's call, we will provide an update on the cytisinicline development program, including our ongoing ORCA-2 study, the great progress we are making on our upcoming clinical trials, and provide an overview of our Q3 financial results. Let's begin with ORCA-2, our current Phase 3 trial evaluating cytisinicline in 810 adult cigarette smokers at 17 clinical trial sites in the United States. ORCA-2 was initiated in October of 2020, and is evaluating the efficacy and safety of three milligrams cytisinicline dose three times daily over a period of six and 12-weeks versus matched placebo. We reached the key milestone of completing our target enrollment in June of this year. All randomized subjects were assigned to one of three arms to receive either 12-weeks of placebo, 12-weeks of cytisinicline or six weeks of cytisinicline followed by six weeks of placebo. All subjects are then followed monthly out to 24-weeks. The ORCA-2 study has two independent primary efficacy endpoints that will evaluate the rate of smoking abstinence in cytisinicline during the last four weeks of treatment, compared to placebo at the end of both six weeks and 12-weeks of treatment. ORCA-2 will be successful if either or both of the cytisinicline arms show an efficacy benefit over placebo. All ORCA-2 subjects have now completed study treatment and are in follow up. We expect the last patient last visit to occur by end of December 2021. And top-line data results to be announced in the first-half of 2022. Achieve will remain blinded until the completion of all study follow up evaluations, and until the database has been finalized and locked. Additionally, planning is well underway for ORCA-3, our proposed Phase 3 clinical trial, which we anticipate to launch by early 2022. ORCA-3 will mirror the ORCA-2 trial and study design, safety and efficacy evaluations and statistical criteria. ORCA-3 will serve as the second required Phase 3 trial to support the cytisinicline regulatory submission in the U.S. Similar to ORCA-2, approximately 750 subjects are expected to be enrolled into ORCA-3 and randomized to one of three study arms to determine the smoking cessation efficacy and safety profile of cytisinicline administered for either six or 12-weeks compared to placebo. To support the initiation of ORCA-3, we have hired three new full time clinical operations employees completed the selection process for the CRO, finalize the packaging and study drug supply, and are currently undergoing clinical trial site selection. We look forward to providing you with additional updates in the coming months, as we progress towards ORCA-3 initiation. We are also making excellent progress on our plans for expansion into nicotine e-cigarettes or vaping cessation. We announced just a few days ago that the FDA has completed their review and acceptance of our IND application to investigate cytisinicline as a cessation treatment for nicotine e-cigarette users. As previously discussed, we have secured non-dilutive grant funding from the NIH to offset costs related to the Phase 2 ORCA-V1 trial, which will enroll approximately 150 adult nicotine e-cigarette users in the U.S. The grant is awarded in two phases, with the initial amount of $320,000 used to complete regulatory and clinical operational activities, such as protocol finalization, clinical trial site identification and the submission of a new IND for vaping cessation to FDA. Upon completion of these milestones, as assessed by NIH, Achieve expects to receive the next stage of grant awards of approximately $2.5 million in early 2022, which will enable execution of the ORCA-V1 study. The funding is subject to authorization by the NIH under the grant process, and is expected to cover approximately 50% of the total ORCA-V1 trial costs. We expect to initiate the ORCA-V1 study in the second quarter of 2022. Recent data indicate there are more than 11 million adult users of nicotine e-cigarettes in the United States alone. While e-cigarettes have historically been viewed as less harmful than combustible cigarettes, their long-term safety remains controversial. Since these products can also sustain addiction, many vapors are now seeking to quit nicotine completely. In research conducted by Achieve roughly 73% of e-cigarette users expressed a desire to quit within 12-months. Of those with a more urgent interest in quitting, more than half indicated they would be interested in a new prescription cessation therapy. Currently there are no treatments specifically indicated to help e-cigarette users quit. So we see this as an unmet commercial opportunity. If our development efforts proved to be successful, cytisinicline may offer a new cessation option for this growing population of e-cigarette users who seek to quit nicotine for good. Finally, in the third quarter, we had two cytisinicline data presentation at the Society for Research on Nicotine and Tobacco Annual European meeting. The first data set evaluated the time to sustained abstinence with cytisinicline compared to placebo in our Phase 2 ORCA-1 trial. This new analysis determined that smokers treated in the study with cytisinicline showed an earlier onset of sustained abstinence compared with placebo. In this cohort, it took smokers who are successful at quitting a median of seven days to achieve smoking abstinence compared to 18-days for placebo. We have seen this early onset of activity in earlier studies, including in our repeat dose PK/PD study, where we saw a greater than 75% reduction in cigarettes consumed within the first 48-hours of initiating treatment. Data were also presented from additional ORCA-1 subgroup analysis evaluating outcomes in smokers who previously failed treatment with Chantix. Smokers who received 3 milligrams cytisinicline, three times daily demonstrated a week for abstinence rate of 51.3% compared with 15.8% for placebo treated subjects. The cytisinicline three times a day regimen appeared to be more effective for smokers who had previously failed to quit on varenicline than the titration regimen. We believe both the speed of cessation and cytisiniclines efficacy and Chantix pretreated smokers bodes well for the Phase 3 development programs and for the commercial prospects of the product. That concludes the overview of our recent highlights. Now I'd like to turn the call over to Jerry, to discuss our financial results.
