Analyst · William Blair. Your line is now open
Thank you, Terry. I would like to begin with our usual summary of the company for those of you who may be new to the story. We are developing ELAD, an extracorporeal human allogeneic cellular therapy, which could improve survival in acute forms of liver failure. ELAD is at the Phase 3 clinical trial stage and has Orphan Drug Designation in the United States and Europe. Assuming successful clinical results in the future, we plan to seek regulatory approval and commercialize ELAD directly in most major markets of the world. VTI-208, our first Phase 3 trial which reported top line data last August, enrolled 203 subjects primarily in severe acute alcoholic hepatitis, but did not meet its primary or secondary survival endpoints. However, encouraging data from pre-specified subgroups combined with post-hoc analysis of combinations of these parameters led us to the design of a new Phase 3 trial called VTL-308, which is underway. The agenda for today's call will be first to review the status of the 308 trial, a second welcome and new addition to our board of directors, Faheem Hasnain, formerly President and CEO of Receptos. Third, update our continuing work on ELAD's mechanism of action. Four, review our financial results. Five and finally, we will open up the call for Q&A. First, we will discuss the status of our VTL-308 phase 3 clinical trial. This trial is our priority and as of today we have enrolled a total of 20 subjects with 33 sites now open in the U.S. and Europe. As we noted earlier in the year, we have been behind plan and site openings. For instance, as of our second quarter conference call in August 2, we had opened 23 sites. Since that time we have opened an additional ten sites and are ahead of our projections for site openings in the U.S. Moreover, we have now worked through bureaucratic challenges we were facing in Europe which were delaying openings on that continent. In order to make up for the delay we saw in Europe, we plan to increase our target to 50 site openings worldwide by the end of Q1 2017. There are 20 subjects currently in the trial compared with 8 subjects as of our report on August 2. Because of the delayed site openings, we are also behind our enrollment projection. However, as I just mentioned, we believe we can make up for that delay by enrolling at more sites and we believe this will preserve our ability to readout data in mid-2018. In sum, we have gone from 20 sites in June to 33 now with a target of 50 by the end of March 2017. This is a very large increase in sites and is expected to have a significant impact on the pace of enrollment. We do acknowledge that enrollment has been effected by our discipline and only enrolling those subjects who meet the trial's criteria. As a result of our trial design, we have an unusual ability to confirm subject eligibility prior to randomization. We believe it is critical we maintain this discipline and only enroll suitable subjects in order to increase the possibility we have a successful result. Finally, we are encouraged that over the last three months we have been enrolling subjects in the 308 trial at almost double the rate of enrollment for those subjects in the 208 trial who met 308 criteria. We have also been gratified to see our rates of screening increase over the course of the trial and we expect this will be further accelerated as we ramp up outreach programs to help our sites identify and enroll appropriate subjects. Switching topic to corporate governance, we are delighted that Faheem Hasnain has joined our board of directors, as we announced on August 15. He has also made a personal investment in our company. Faheem was formerly President and CEO and a Director of Receptos, which was developing auto-immune drugs and was acquired by Celgene last year for $7.8 billion. Prior to Receptos, Faheem was CEO of two biotechnology companies after a very successful career in the drug and biologic business with several large biotech and pharma companies. His experience will be invaluable to Vital Therapies as we plan for the possible commercialization of ELAD. Faheem has agreed to chair a new commercialization committee of the board that will also include JJ Bienaime, CEO of BioMarin, Cheryl Cohen, former Chief Commercial Officer of Medivation, Phil Croxford, CEO of Gamma Medica, and Doug Godshall, former CEO of Heartware. We welcome Faheem to our board and look forward to working with him. On the R&D front, we have presented two posters and made related presentations at an international symposium on liver disease, which took place in mid-September in Rostock, Germany. Both presentations can be found on our Web site. The first poster is titled Hepatic Inflammation and Cellular Therapy. It reported data from laboratory studies that describe how VTL C3A cells secrete known anti-inflammatory factors in response to certain pro-inflammatory substances which are known to be present in increased amounts in subjects with alcoholic hepatitis. Preliminary data in a small subset of subjects from prior ELAD clinical trials suggest that this maybe a potential mechanism by which cell based treatments such as ELAD may provide benefit to patients with alcoholic hepatitis. The second poster is titled VTL C3A Cell-Secreted Factors Reduce In Vitro Hepatocellular Injury via Multiple Mechanisms. It discussed mechanisms by which our cells may promote hepatocyte survival. One such mechanism is the inhibition of Apoptosis also known as programmed cell death. This may improve liver function and may increase survival on patients with severe acute alcoholic hepatitis. We continue to work on mechanisms of action focusing particular effort on the impact of factors secreted by our cells on other cell types in the liver such as endothelial cells that line the walls of blood vessels. We are also developing blood cell models to study the effect of these secretive factors. This is pertinent because the ability of white blood cells to fight infection is known to be impaired in patients with severe alcoholic hepatitis, likewise improvement in white cell function may provide an avenue for obtaining therapeutic benefit. Before turning the call over to our CFO, Mike Swanson, for a review of our financials, I have a corporate update to report on. A securities class action complaint was filed earlier this year in the Southern District of California against the company and certain of its officers alleging securities law violations. This complaint was voluntarily dismissed by plaintiffs in August. No payments were made in connection with any of the plaintiffs claims and at this time there is no litigation pending against the company. I will now turn the call over to Mike.
