Thank you, Al and good afternoon everyone. Welcome to our second quarter 2016 update call. Our prepared comments will be relatively brief this afternoon. First, our usual summary of the company for those of you who may be new to our 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 U.S. and the EU.

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.

VTI-208 in 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, the encouraging data from pre-specified subgroups combined with post-hoc analysis led us to the design of a new phase 3 trial called VTL-308, which is now in progress.

The agenda for today's call will be to review the status of the VTL-308 trial and then to update on our continuing work on ELAD's mechanism of action, to review our financial results, and finally, we will open up the call for Q&A.

So first, the status of or VTL-308 phase 3 clinical trial; this trial is our priority and the quarter has been one of blocking and tackling to implement the details of clinical trial management, including regulatory filings, signed contract details, and screening and enrolling of subjects.

As we announced on May 23, we achieved our goal of enrolling the first subject in the trial during the first half of this year. As of today, we have enrolled a total of eight subjects in the VTL-308 trial at sites in the United States and Europe. Currently 23 sites were opened for enrollment in the U.S. and in Europe.

And they are all actively screening subjects. We are not using a CRO to run this trial; we're going to managing it ourselves under the capable direction of Andrew Henry, our VP Clinical Operations. In addition to giving us more control over the progress of the trial, we believe that our direct management time yields time and cost savings.

We also believe we are still on-track to deliver top line results for our VTL-308 trial by mid-2018. However, it is early in the trial process and we need to continue to open sites and to screen and enroll patients.

Turning to our R&D, we have continued to work on the mechanisms by which our VTL C3A cells prevent the death of human liver cells in cell culture. Some of these data have been submitted through presentations at scientific meetings later this year.

We are also continuing our work to relate the mechanisms of action that we have elucidated over the past year through outcomes in our past clinical trials. This is being done primarily by searching for markers of information, regeneration, detoxification, and cell death.

In blood samples taken from treated and controlled subjects in the VTI-208 trial, we hope to report more of this soon. I'll now turn the call over to Mike Swanson, our Chief Financial Officer..

Thank you, Terry. We ended the second quarter with cash and cash equivalents of $73.6 million. Our average monthly cash usage for operations and capital expenditures during the first six months of the year was approximately $3.2 million. We expect our use of cash will vary based primarily on the timing of enrollment in our VTL-308 trial.

Through June 2016, we have now raised net proceeds of $8.8 million under an at the market sales agreement since initiating the program in March selling 1.1 million shares at an average price of $8.71 per share.

Summarizing our results for the quarter ended June 30, 2016; the company reported a net loss of $9.5 million or a $0.30 basic and diluted loss per share. Non-cash expenses for stock-based compensation, depreciation and amortization totaled $1.5 million in the second quarter of 2016.

This compared to a net loss of $15.1 million or $0.63 basic and diluted loss per share for the second quarter of 2015 which included non-cash expenses of $1.3 million dollars for stock-based compensation, depreciation and amortization.

For more details on these financial results please refer to our press release issued today and our 2016 Quarterly Report on Form 10-Q. Thank you. And with that I'll turn it back to Terry..

Thank you, Mike. Before we take your questions, I would like to summarize our anticipated key upcoming milestones. First, there will be quarterly reports on the progress of the VTL-308 clinical trial. Second, there will be additional presentations on ELAD mechanism of action expected at various scientific meetings in 2016.

Third, a possible publication of the VTI-208 results in a peer reviewed journal later this year. I would now like to open up the call to your question in addition to Mike joining me for the Q&A portion of our call are Dr. Duane Nash, our President; Rob Ashley, EVP and Chief Technical Officer; and Dr. Jan Stange, Chief Medical Officer.

Operator, could you please provide instructions and open up the call for questions..

Thank you [Operator Instructions]. Your first question comes from the line of Katherine Xu of William Blair. Your line is open..

Thank you, and good afternoon. I have a couple of questions. So with regard to the enrollment of VTL-308 you already eight patients. I'm just wondering how many patients did you screen to actually enroll those eight.

Is that percentage higher or lower or in line with your expectations based on -- supports the time as much for restricted inclusion criteria?.

Can we take that question first?.

Sure..

Great.

Duane would you expand on it?.

Yes, there is are two different levels of screening or prescreening as when we look at everyone who was in the vicinity of the inclusion criteria and then as the actual screen level is when patients come close to qualify and paperwork is submitted through the site.

So for those and I'm only referring to the second level, we've screened 17 subjects to get 8 enrolled..

You said you had another question Katherine..

Yes sir, I didn't quite hear.

How many patients did you screen to get the 8 enrolled?.

17 that are on the database we have screened in order to get those -- of course we reach out far into referring sites and pre-screen for larger number of patients of course..

Got it. My other question is more kind of theoretical, so we understand that in the retrospect its subgroup analysis from the 208 study where you had the 60 patients that had to be pretty much include criteria for the phase 3 study right now.

And in those -- in that subset, had their ratio exceedingly to 0.28 and the survival 90 day, 180 day or we thought so very meaningful. But of course at the same time this is again retrospective, sub-growth analysis which is such as that they are strong or weak.

I wonder could you name a few prior studies that are of the similar nature -- it was based on the retrospect and subgroup analysis that turned out to be successful..

You mean our analysis or someone else's?.

Someone else's -- sort of any precedent of this because I think what is in people's mind are -- on the one hand the subgroup analysis seems to be very strong but of course it's compromised by the theoretical risk there just embodied with the subgroup analysis.

So just wondering from your survey of literature any success with studies that were actually turnout base [indiscernible] analysis?.

Rob, you want to take down?.

I think one that sort of springs to mind was the dungeon [ph] work were originally subgroups proved. The whole analysis proved negative and then subgroup analysis but were then proven prospectively supported the marketing authorization and the ELAD filing.

Every situation is different and I think what I would say Katherine is that whenever you do a clinical study, you learn something which you then apply to the next clinical study, and in a sense that way evolving clinical development program is evolving as a result of the data that you had previously.

In our case, whereas you're absolutely, right; the subgroup analysis were post-hoc and albeit based on pre-specified data. I think as this development program has evolved all the way through, we learn from our previous studies and apply those learnings to maximize the opportunity for the next study.

And I think that's probably true of a lot of the biotechnology industry..

Thank you..

Your next question comes from the line of John Newman with John Newman with Canaccord. Please go ahead..

Hi guys, thanks for taking the question.

I just wondered are you using the same number of clinical sites as the prior phase 3 in terms of enrolling patients? And can you describe the process with the Data Safety Monitoring Board for the study in terms of how often know there will be meaning to take a look at the study to see how it's coming along? Thanks..

Well, the answer to the first question is we're using about the same number of sites. As I recall we had just over 40 sites in VTI-208 and we couldn't be using approximately the same number here. For the second question I think I'd like to ask Dr. Stange to respond..

The Data Safety Monitoring Board -- now look on this staff American and European members and they will meet once monthly and we'll always be updated about the course of adverse events, severe adverse events coming into the trial which of course also bad..

Right.

And given the studies open label, do you plan on taking any interim looks or at this point you just plan on waiting until the studies complete?.

We are not planning any internal looks..

Okay, great. Thank you..

[Operator Instructions] Your next question comes from the line of Edward Nash with SunTrust. Your line is open..

Hi, this is Mike Guo for Edward, thanks for taking the question. So two question; first one is that if I'm not mistaken, you have two of -- five events in order to close the trial, a phase 3 trial.

So have you observed any kind of mortality from the trial?.

My response is too early to comment on that..

Yes, we haven't looked at the mortality events.

Rob, do you want to talk in a general sense about how we're going to assess the 55 after we've enrolled a 150?.

Yes, we will look at the overall mortality rate for this study and if that rate is unexpectedly low then we have the opportunity to expand the study. We won't be looking at the mortality rate between the control and ELAD arms. But at the moment obviously, with just 8 patients enrolled, we're way too early to estimate that..

Okay, got it. That's helpful..

So do you have another question Mike?.

Yes, I have another question.

So regarding the funding for phase 3 trial, so just wonder for ATM how much remain do you have -- can you draw from ATL and whether that amount of money can be sufficient to fund the phase 3 trial data?.

Duane?.

I believe the size of the ATM in series 75 million, but we have no intention of drawing down anywhere near that amount on the ATM. I think we've said that current cash still gets us into early 2018 and data is mid-2018.

So I'm not sure we find any more color on precise numbers but I think one can get a sense that that's not a tremendously large number..

Okay, got it. That's helpful. Thanks a lot..

Thanks..

Ladies and gentlemen, there are no further questions at this time. I'll turn the call back to the presenters for closing remarks..

Okay, well thanks for joining us on the call, appreciate all the questions. Have a great rest of the summer, and we'll see you on the next call I believe probably sometime in early November. Meantime, we're going to continue our blocking and tackling. Bye..

Ladies and gentlemen, this concludes today's conference call. Thank you for your participation and have a wonderful day. You may all disconnect..
