Thank you, Nicole, and thank you, everyone, for joining us today. As you've probably heard, last month, we reported a highly successful outcome of the ORCA-2 Phase III clinical trial of cytisinicline for smoking cessation. Cytisinicline demonstrated impressive efficacy across the primary and secondary endpoints for both the 6- and 12-week cytisinicline treatment arms. The safety and tolerability profile remains best-in-class with single-digit rates of adverse events reported. We could not be more excited that cytisinicline succeeded in the challenge of helping many long-term heavy smokers in whom previous treatments have failed, successfully kicked the habit. And the timing could not be better to bring a new cessation option forward. For the first time in over 20 years, cigarette sales increased during the COVID-19 pandemic, while calls to quit lines dropped by nearly 30%. There is still more than 30 million smokers in the U.S. alone and over $1 billion globally who have not been offered a new regulatory approved treatment in nearly 2 decades. Smoking kills more people every year than alcohol, AIDS, car accidents, illegal drugs and murders combined. In the U.S., it accounts for more than 480,000 deaths and billions in health care dollars spent each year. Yet despite these alarming statistics, there have been very few clinical advances, aiding smokers and health care providers to treat nicotine addiction. CHANTIX, which was FDA approved in 2006 and withdrawn from the market last year, was the leader in the smoking cessation category, generating over $1 billion in peak sales before going generic, with roughly 75% of those sales attributed to the U.S. market. While it has been considered the most efficacious treatment currently available, it was never able to reach its full potential of helping more people quit successfully due to its side effect profile. In fact, when marketed, only 4% of the U.S. smoking population were prescribed CHANTIX each year. And in the ORCA-2 trial, less than half of the participants had ever used CHANTIX in their multiple prior quit attempts. Insights from our research and from smoking cessation opinion leaders and prescribers suggest that the primary reason a majority of smokers avoid starting or completing a full 12-week course of CHANTIX is due to the high incidence of side effects, such as nausea, headaches and sleep disturbances. Based on prior evidence, we have always believed that cytisinicline could offer a more tolerable alternative, and we now have proof from a randomized Phase III study of more than 800 smokers to support this belief. The adverse event profile appears to be best-in-class with more headaches and nausea in the placebo arm than in the active treatment groups. In addition, the odds ratios we observed in ORCA-2 are unprecedented, with 6 to 8x higher odds of quitting at the end of treatment compared to placebo. And our quit rates were impressive despite the highly addicted study population and the execution of the trial during a pandemic. We are excited to see that both 6- and 12-week courses of cytisinicline therapy appeared to be highly effective for smokers. The 6-week therapy option provides flexibility for a shorter treatment to achieve abstinence and is half the duration of current treatments. And finally, quite simply, it is a new option smokers and their doctors need new solutions. This is an indication that has not seen any new approved treatments in more than 15 years. We believe a new treatment option will provide hope to the millions of smokers who are ready to finally quit. We plan to offer that hope with cytisinicline. Turning to the top line data readout, I'd like to hand it over to Cindy to review the key findings from the ORCA-2 trial. Cindy?
