Analyst · Ladenburg Thalmann. Your question, please
Thank you, Jaime. On today’s call, we’ll provide an update regarding Achieve’s recent progress on the cytisinicline development program, plus upcoming clinical milestones. Following that discussions, I will provide a review of our first quarter financial results. Beginning with ORCA-1, which is our Phase 2b dose optimization trial comparing the efficacy and safety of cytisinicline versus placebo. We're evaluating both 1.5 and 3-milligram doses using the established declining titration schedule in addition to three times daily dosing over a 25-day period. Participants in the trial are monitored for four weeks post treatment and are provided face-to-face behavioral support over the full course of this study. ORCA-1 has enrolled a total of 254 smokers at eight centers across the U.S. Since the beginning of the year, subjects were recruited in record time with approximately 90% enrollment within seven weeks. We announced on April 24th that a last subject in the ORCA-1 trial had completed their last study visit. Our clinical research organization is now focused on monitoring data from the sites and data base finalization. We expect to announce top-line data results by the end of this quarter. I want to provide further clarity about the objective of this trial and the potential outcomes. To do that, we have to revisit the results of the cytisinicline repeat dose study that was presented at the Society for Research on Nicotine and Tobacco in February. As a reminder, this was not a smoking cessation trial but rather a small study intended to evaluate the pharmacokinetic and pharmacodynamics of 1.5 and 3-milligram doses using that downward titration schedule. There were no formal quick dates set and only minimal smoking cessation counseling was provided. The data gave us a clear signal about two findings. Firstly, the level of reduction in number of cigarettes smoked. On average, subjects in both groups smoked 17 cigarettes a day at baseline. Within 48 hours of initiating treatment, they had reduced the number of cigarettes smoked by 75% and this was sustained throughout the course of treatment. Secondly, subjects taking a higher 3-milligram dose showed a trend towards better efficacy. This arm demonstrated a 54% quit rate of the under treatment versus 39% on the 1.5 milligram dose. This is a dose that is currently marketed in Central and Eastern Europe and has already treated over 21 million patients. This trend is worth investigating further to see if we can improve on both, reduction in cigarettes smoked and quit rates. At our meeting with the FDA in May of 2018 we were given clearance in principal on our Phase 3 clinical trial design. Based on the outcome of this meeting, Achieve chose to derisk the Phase 3 trial program by further exploring the optimum dosing schedule. We are currently evaluating whether the 1.5 milligram titration dose over 25 days can be improved by using either a 3-milligram titration dose or dosing three times daily with 1.5 or 3 milligrams. For the ORCA-1 trial, the key elements that will be assessed are efficacy, dosing administration and confirmation of the safety profile cytisinicline. The primary efficacy endpoint is reduction in cigarettes smoked over the course of treatment. Secondary endpoints that will be evaluated include the smoking cessation rate, which is the approval of Phase 3 endpoint, as well as safety and compliance. The ORCA-1 trial is designed to show a statistically significant difference in reduction of cigarettes smoked versus placebo. However, given the small number of participants per group, it is not powered to show statistically significant difference in overall quit rates. As discussed, dosing and scheduling will be evaluated across full treatment arms for a treatment period of 25 days. The 1.5-milligram dose administered three times daily, giving a total of 103.5 milligrams of cytisinicline, the 1.5-milligram dose on a downward titration schedule over -- for total of 150 milligrams, the 3-milligram dose, three times a day for a total of 207 milligrams, and finally, the 3-milligram on a downward titration schedule for total of 300 milligrams. Three out of four of these arms delivered total dosage of cytisinicline at or above what is currently marketed in Central and Eastern Europe. This increases our confidence in having one or more arms that will demonstrate an efficacy benefit. This comparison also allows us to evaluate whether a higher dose of cytisinicline can improve efficacy while maintaining safety and tolerability. In addition, the three times daily dosing may provide a more convenient administration option for smokers. We believe the historical safety profile of cytisinicline is a key point of differentiation compared to currently available treatment for smoking cessation. As previously announced this quarter, an independent data safety monitoring committee or DSMC, has conducted two evaluations of the ORCA-1 trial and concluded that there are no safety or conduct issues and that the trial should continue to completion. After conducting a thorough analysis of the efficacy and safety data across the four arms evaluated in ORCA-1, we will be better informed to select the Phase 3 dose and administration schedule as well as confirm our Phase 3 development plans with the FDA. In addition to the exciting ORCA-1 progress, we have an important update on another critical NDA-enabling study. In March, we initiated a trial to assess dose limiting effect -- events, and to define a maximum tolerated dose or MTD for a single administrated oral dose of cytisinicline in smokers. The study design had a starting dose of 6 milligrams in a single administration to be increased in 3-milligram increments over -- until dose-limiting adverse events occurred. Six dose levels were planned with 21-milligram as defined as the highest level of cytisinicline to be evaluated. Following each dose level, a safety review was conducted by an independent DSMC before escalation to next dose. To-date, a single 21-milligram dose of cytisinicline has been evaluated without evidence of dose limiting toxicity. DSMC has recommended that a protocol be amended to evaluate higher doses, up to 30-milligram of cytisinicline pending ethics committee approval. This study further supports the safety profile of cytisinicline and its potential to provide a differentiated treatment option for smokers with a better side effect profile from the currently available prescription smoking cessation treatments. I’d now like to provide an update on our cash balance as of March 31, 2019 and also our operating expenses for the first quarter of 2019. As of March 31, 2019, the Company's cash, cash equivalents, short-term investments, and restricted cash were $9.7 million. Our cash balance allows us to execute on our near-term development plan, including the completion of the ORCA-1 trial by the end of the second quarter. Turning to our statement of operations. The Company incurred a net loss of $5.9 million for the quarter ended 31st of March, 2019 as compared to a net loss of $3 million for the quarter ended March 31, 2018. Research and develop expenses in the first quarter of 2019 increased to a total of $4.1 million, compared to $1.2 million in the first quarter of 2018. General and administrative expenses for the quarter ended March 31, 2019 were $1.9 million, compared to $1.8 million in the quarter ended March 31, 2018. As expected and highlighted during our call in March, operating expenses were elevated in the first quarter as we reached full enrollment in our ORCA-1 trial. We expect our quarterly operating expenses to decline over the next two quarters, in line with the completion of the ORCA-1 trial by the end of the second quarter. So, in summary, we continue to make tremendous progress in driving forward this critically important therapy for smoking cessation and nicotine addiction. We expect our upcoming ORCA-1 results to inform our Phase 3 trial plans and also to provide robust clinical data that will be critical for strategic discussions with potential commercial partners in the U.S. and the rest of the world. We look forward to maintaining our momentum and providing you with continued updates in the near future. Thank you again for your ongoing interest in Achieve. We will now open the line for questions.
