Thank you, Jaime. On today's call, we will review the progress we've made on the Phase III trial and other NDA enabling activities and provide an update on our Q1 financial results. Let's begin with ORCA-2. As a reminder, ORCA-2 is a double-blind, randomized, placebo-controlled Phase III trial that is currently enrolling 750 adult smokers across 17 locations in the US. The trial is designed to evaluate the safety and efficacy of 3-milligram cytisinicline dosed three times a day over a period of six and 12 weeks versus placebo. Participants are being randomly assigned to one of three arms and receiving either 12 weeks of placebo, 12 weeks of cytisinicline or a combination of six weeks of cytisinicline followed by six weeks of placebo. After the 12-week treatment period, subjects are followed monthly out to 24 weeks. Behavioral support is being provided to all subjects throughout the study. There are two independent primary endpoints that will evaluate the rate of smoking abstinence of cytisinicline 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. We are pleased to share that ORCA-2 has reached over 80% of the 750 subjects enrollment target, and we look forward to completion of enrollment by the middle of the year. As we discussed on our last call, we experienced slower than anticipated enrollment during the initial months of the study, which was primarily due to the pandemic and participants reluctancy for in-person site visits. In response, we implemented numerous recruitment initiatives to increase the pipeline of potential subjects to be screened and successfully assisted the site's in finding qualified subjects for the trial. We also onboarded two new clinical sites in Atlanta, Georgia and Evansville, Indiana, bringing the total number of sites in the study to 17. We are pleased to see the additional recruitment support the new sites have resulted in increased randomization, and we remain on track to completing enrollment by the middle of this year. Additionally, regarding our Q2, we have completed two data safety monitoring committee meetings. The committee reviews general safety data and oversees the conduct of the trial. In both meetings, they did not identify any safety concerns nor any study conduct issues and recommended that the study continue as planned. Overall, we are pleased with the progress of the trial to-date and the efforts being made by our clinical trial sites across the US. As a reminder, the company will remain blinded, until the completion of all study follow up evaluations and until the database has been finalized and locked. We look forward to providing further updates on ORCA-2 when enrollment is completed. Additionally, we have continued to make great progress on numerous non-clinical NDA enabling regulatory requirements. We have completed and submitted to FDA both of the required long term chronic toxicology studies. In addition, we are also near completion of one of the two required carcinogenicity studies and have completed a special protocol assessment with the FDA for the second required study. By next year, we expect that all required non-clinical toxicology studies for an NDA will be completed. Also, in the first quarter, we had two important cytisinicline studies published in leading peer reviewed scientific journals. First, the results from Achieve Phase 2 ORCA-1 trial, demonstrating superior quit rates for cytisinicline compared to placebo and impressive safety responses was published in nicotine and tobacco research. As a reminder, this study was instrumental in the selection of the 3 milligram dose and 3 times a day administration that we have taken forward into Phase 3 development. Additionally the New Zealand RAUORA study showing improved efficacy and lower rates of adverse events when comparing cytisinicline to CHANTIX was published in the journal addiction. We expect additional efficacy analysis from RAUORA, in the coming months and look forward to sharing that with you when available. Finally, this quarter we announced the appointment of 2 new Directors to Achieve Board. Dr. Bridget Martell and Dr Cindy Jacobs. Dr Martell is Board certified in both internal and addiction medicine and is an experienced executive leader in the pharmaceutical industry. Dr. Jacobs serves as Achieve’s President and Chief Medical Officer, and in addition to her board duties, will continue in her current role, leading Achieve’s regulatory and clinical development efforts. The appointment of Dr. Martell and Jacobs strengthens both our Board diversity, as well as our clinical and regulatory expertise. At this time, I'd like to turn the call over to Jerry to discuss our recent financial results. Maybe having an issue with Jerry's connection, so let me jump in. I'd like to provide an update on our cash balance as of March 31, 2021 and our operating expenses for the first quarter of 2021. As of March 31, the company's cash, cash equivalents, short term investments in restricted cash were $29.6 million compared to $35.9 million as of December 31, 2020. We believe our cash balance is sufficient to provide runway into the middle of 2022. Turning to the statement of operations, the company incurred a net loss of $8 million for the quarter ended March 31, 2021 as compared to a net loss of $3.3 million for the same quarter of 2020. Total operating expenses in the first quarter of 2021, increase to $8 million as compared to $3.4 million for the same quarter of 2020. As expected and highlighted during our call in March, operating expenses were elevated in the first quarter as enrollment in the ORCA-2 trial increased. We anticipate our operating expenses to remain elevated during 2021, as we continue to execute on the ORCA-2 trial. In closing, we continue to make excellent progress on advancing cytisinicline through the required clinical and regulatory development process. In the first quarter, we saw significantly increased interest in momentum in ORCA-2, and look forward to the completion of enrollment in the middle of this year. Additionally, we continue to execute on the required NDA-enabling activities and publication of key data to expand awareness of cytisinicline’s potential across new audiences. That concludes our prepared remarks. Thank you again for joining us. We will now open the line to questions. Operator?
