Analyst · William Blair. Your line is open
Good afternoon everyone and welcome to our first quarter 27 update call, 2017 update call. Before I start my apologies for my voice I'm recovering from a nasty cold but I assure you that it is the same old Terry. So let's begin with our usual summary of the company. And 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 III clinical trial stage and has Orphan Drug Designation in the U.S. and EU. We are currently enrolling subjects in VTL-308, a randomized controlled trial in severe acute alcoholic hepatitis, topline data are anticipated around mid-2018. Assuming successful clinical results in the future, we plan to seek regulatory approval and to commercialize ELAD directly in most major markets of the world. The agenda for today's call is as follows: first we'll review the status of the VTL-308 clinical trial. Then discuss the details of our recent financing and how it extends our cash runway. Third, provide an update on their preparations for the submission of an ELAD biologic license application or VLA to the FDA in the event of successful VTL-308 trial results. Then we will summarize our plans for commercialization of ELAD, again assuming successful trial results. Then update our continued work on ELAD's mechanism of action, review and financial results and finally we will open up the call for questions and answers. So first, we discussed the status of VTL-308 Phase III clinical trial. As many of you know, this trial is our top priority since successful results are essential for us to move to PLA submission and then to commercialization. As of Monday, we had enrolled 67 subjects in the trial in the U.S. and the EU and we now have 46 clinical sites open for enrollment. Over the last six months, we have been averaging about 8 subjects enrolled per month and as of the end of April we were at 0.19 subjects per site per month compared with our target of 0.2 which we talked about in our last call. While we are little behind this target as we have said before, enrollment will fluctuate from month-to-moth and we still expect to report top line data around mid-2018. Next, a discussion about recent financing; I am very pleased to report that in March we completed the following offering raising $37.8 million dollars after underwriting discounts and commissions. We believe our current cash position could take the company through the first quarter of 2019 well past the expected announcement VTL-308 topline trial results. With the financing addressed we are now focused on completing enrollment of the trial. So next we would like to give you some information on that preparations for the ELAD-BLA, in the event of course of positive results. The ELAD system is regulated as a combination biologic product by FDA. It is comprised of 4 cartridges that contain VTL C3A cells, constituting the biological product, connected to a bedside delivery system, which circulates the patient's plasma through the cartridges and returns the treated plasma back to the patient. The whole system is regulated by the Center for Biologic Evaluation and Research Division of FDA or CBER, and specifically by its office of tissues and advanced therapies. It is important to note that the bedside delivery system does not need separate approval by the FDA's medical device division although the division does provide advice about approval to CBER. Europe is similar, although the terminology is different. The licensed application in the EU is known as a market application authorization or MAA and ELAD is classed as an advanced therapy medicinal product or ATMP in the EU. We plan to submit BLA to the FDA 9 months after announcing the topline results of the VTL-308 clinical trial. To do it faster than this would require the addition of significant resources and expenses before the topline results are available. We currently believe that this BLA submission will be granted priority review by the FDA. Priority review is granted for drug applications that if approved would represent significant improvements in the safety or effectiveness of the treatment of serious conditions when compared to current standard of care. In the event of successful trial results, we believe a BLA submission for ELAD would qualify under the standard. The FDA determines whether an application will have priority review designation within 60 days of the BLA submission. And if priority review designation is granted, the FDA's goal is to take action on an application within 6 months or a total of 8 months from submission which is 4 months shorter than the FDA's goal for a standard review. So now let's turn to an outline of some of their plans for commercialization. Again, assuming positive results from the VTL-308 clinical trial, for commercialization comments, we are grateful to the deep experience that we have on our Board of Directors with pharmaceutical commercialization For this call, we will discuss our marketing strategy and manufacturing, And future quarterly calls, we'll discuss other aspects of commercialization, marketing strategy. We have discussed the large market potential for ELAD before in our corporate presentation. And we intend to address this significant opportunity by marketing ELAD ourselves in most of the major countries of the world with the initial focus on the U.S. and the EU. Since it is crucial that we safeguard the standard of delivery of clinical care, we plan to restrict the hospitals offering ELAD therapy to large academic centers and prominent community hospitals. In practice, these were primarily the liver transplant centers and hospitals with advanced liver therapy programs, which we estimate there are at least 200 in the U.S. many of which will be our existing clinical sites. Our current plan is of course for getting growth by adding more bedside units at these established centers rather than adding more hospitals. We expect that other hospitals in surrounding areas will refer patients to the ELAD treatment centers. We intend to continue sending our own specialists to the hospitals to manage the delivery of the ELAD therapy, to ensure the highest clinical standards. But overtime, some hospitals may be able to use their own staff. We plan to place ELAD account executives in the field, who are experienced in liver disease and assign them a relatively small number of hospitals to cover. We anticipate there will be multiple physicians at each hospital, who can order the therapy and the account executives must be capable of interacting at the physician level. Reimbursement is of course crucial and we will cover this in the future investor call. However, for context ELAD is intended to be a life-saving therapy in an orphan indication, which characteristics usually quite helpful in establishing reimbursement. Education and awareness of alcoholic liver disease are also important components of our commercialization of strategy. Now working with our clinical sites, principal investigators and court leaders and ways to reach them provide more information to persons and families affected by this terrible disease. To that end, we have also reached out to and recently engaged with the American Liver Foundation, to aid and encourage them in their educational outreach on alcoholic liver disease including alcoholic hepatitis to the patient community the medical community and other stakeholders. Now to manufacturing, we are fortunate to have a manufacturing plant and processes in San Diego that we believe to meet our needs for commercial introduction. Unlike most other biotechnology companies, we do not contract out the manufacture-- the manufacturing of our drug substance or our drug product. In any case, these are the C-3A cells and the cells in the ELAD cartridges respectively. As currently equipped, we estimate how a plant is capable of producing about 600 ELAD cartridge sets per year, although, we have only operated it at about 100 sets per year for the finical trials. 1 set is 4cartridges used to treat one subject. With a modest additional investment, we believe this capacity can be increase to about 2000 sets per year. And with significant additional investment we believe the San Diego site could be increased to about 4000 sets per year, which represents capacity that we believe could support up to several hundred million dollars in future sales at currently anticipated pricing. For larger volumes, we would need to build a larger plan at different - at a different location. We intend to build future capacity against demonstrated need. Of course, we have only operated our commercial bioreactors to produce multiple cartridges at the development stage. And it could take more time than we expect to optimize the commercial process, increase capacity and generate revenue. Next, let's turn to the continuing work we are doing to elucidate ELAD's potential mechanism of action conducted with the involvement of an eminent Scientific Advisory Board. The new area of investigation the mechanism of action involves the reduction of oxidative stress. This has been shown by third parties in independent research to be a major contributor to cell activation and cell death in the livers of alcoholic hepatitis subjects. Prior Metabolomics Analysis have suggested that there were fewer markers of oxidative stress in the plasma of ELAD-treated subjects. Further work in cell-based models confirms that results are - powerful intracellular antioxidant increased is hepatocytes and endothelial cells when exposed to ELAD condition median. Current investigation is focused on mapping the specific enzyme pathways involved in these cells. It should be noted that most of that mechanism in actual work has been carried out in laboratory based studies, with only limited work involving samples from our clinical subjects. And therefore these findings may not extrapolate to our cynical population. We are also continuing our research collaboration with Drexel University in Philadelphia and the University of Birmingham in the UK exploring the potential for ELAD to resuscitate marginal donor livers, and thereby increase the supply of livers available for transplantation. We look forward to providing an update after we have collected more data. Finally, one of the principal investigators in both of our Phase III trials is presenting some additional data on VTI-208 at the International Liver Transplant Society meeting in Prague later this month. These data are examined the prognostic value of the - score and algorithm incorporating change in bilirubin to predict survival in ELAD-treated subjects. I'll now turn the call over to Mike Swanson for a discussion of our first quarter financial results. Mike?
