Stephen T. Lundy
Thank you, Josh. And thanks to everyone for joining us on the call today. First and foremost, we will provide an update on our ongoing pivotal study for APPY1, then I'll hand it over to Don, who is joining us on the call today from Europe to provide an update on our market development activities in Europe. I'll start with the clinical update. Yesterday, we announced that the ongoing U.S. pivotal study passed the first of 2 scheduled interim futility analyses under the protocol. The assessment was performed by an external Data and Safety Monitoring Board on the first 579 patients to complete the study, including the required patient follow-up period. The analysis involved an independent review of the validity, integrity and clinical and scientific relevance of the ongoing study, and, following this analysis, the external Data Safety and Monitoring Board recommended that the pivotal trial continue. While the test performance of the study remain blinded to Venaxis, this is an important milestone in the trial and allows us to continue to focus on enrolling the rest of the planned 2,000 evaluable patients as quickly and efficiently as possible. At this point, we have approximately 830 patients who have either completed or currently enrolled in this study, awaiting the required 2-week follow-up, following the release from the hospital with initial diagnosis of negative for appendicitis. We're very pleased to say that the rate of patient enrollment continues to accelerate. The study is now enrolling patients from all of our participating hospital sites, and patient recruitment continues to improve on a month-by-month basis as we continuously work with the sites to further enhance the enrollment process. Based on our experience enrolling the previous 500-patient study of APPY1, which was conducted in 2011, we had estimated the completion of the clinical study and submission to the FDA by the end of the year. Now having the benefit of increased visibility into actual enrollment rates and behaviors of our hospital sites, we believe we are still on track to complete enrollment and announce top line data by the end of this year, with FDA submission to follow as soon as possible thereafter in Q1 2014. We've identified the primary reason for the initial slower-than-expected enrollment rate, the first of which is that while we nearly tripled the number of hospital trial sites, this required adjustments to the way we manage training and oversight at the individual hospital level. We are also fortunate to receive additional regulatory guidance from FDA for the study, which modified the trial design, specifically the way candidate patients are identified and recruited into the study, making it slightly more stringent to make sure we're evaluating the right patients. Managing these additional factors took a little extra time. We are now seeing enrollment trends improving. We feel confident in our updated estimate for the timing of trial completion by year end. Once enrollment is completed and the database is locked, we will finalize our FDA submission package as promptly as possible. As the trial continues, we plan to provide another update on enrollment following the second external futility analysis, which is scheduled to occur after the study has enrolled approximately 1,200 patients. We anticipate making an announcement about the outcome of that data analysis following its completion. As we focused on trial enrollment in the U.S., we are pleased to see our efforts to potentially reduce the number of unnecessary CT scans further validated by a large, retrospective study published in JAMA Pediatrics, which is the pediatric journal of the American Medical Association. The findings of this large observational study highlighted the importance of reducing unnecessary CT scans in children because of the significant cancer risk. The study measured the rate of use and radiation dose of CT scans performed over recent years on children under the age of 15 and found the risk of radiation-induced solid cancers was highest for patients undergoing CT scans of the abdomen or pelvis compared to other types of CT scans. Use of abdominal and pelvic CT scans also had the sharpest increase over the study period with possible appendicitis cited as a leading cause for performing an abdominal/pelvic CT. The JAMA Pediatrics study concluded by highlighting the urgent need for more research to determine when the use of CT scan leads to improved health outcomes and when other imaging and non-imaging diagnostic techniques might be as effective. We believe this recommendation, which has been shared by other similar studies as well as by the FDA in its initiative to reduce unnecessary radiation exposure, aligns very well with the APPY1 Test Venaxis is advancing. The peer-reviewed study was featured in The Wall Street Journal and on the NBC Nightly News as well as key industry publications that reach potential users of APPY1, including the Newsletter of the American College of Emergency Physicians, which we believe further enhances the relevance of this landmark study. Turning to our financial position, which was recently strengthened substantially with the $14.4 million in gross proceeds from our May 2000 public offering led by Piper Jaffray & Company. We currently estimate our cash balance to be approximately $20 million at the close of the second quarter 2013, which you will see reflected in our Form 10-Q when we file it in the coming weeks. Importantly, with the strength in financial position, we now believe we have funds to complete the FDA's clearance process and implement the commercial milestones necessary to bring the APPY1 Test into the hands of hospitals and clinicians in the United States and Europe. Before Don provides an update on our market development activities in Europe, I want to highlight that we further strengthened our team with a new board member in this past quarter, Dr. Stephen A. Williams, who is Chief Medical Officer at SomaLogic, one of the leading protein biomarker discovery and clinical diagnostic companies. As you know, we also added Danaher executive, Sue Evans, to the board last quarter. These are 2 highly experienced diagnostic veterans who remain active and in the trenches of major companies in our field. We look forward to continuing to benefit from their deep experience, which will be invaluable to our future growth. And with that, I'll turn the call to Don.
