Good morning. My name is Shelby and I will be your operator today. At this time, I would like to welcome you all to Celsion’s 2019 Financial Results Conference Call. All lines have now been placed on mute to prevent any background noise. Following the speakers' remarks, there will be a question-and-answer session. [Operator Instructions]At this time, I would like to turn the call over to Kim Golodetz. Please go ahead, ma’am.

Thank you and good morning, everyone. Welcome to Celsion Corporation’s conference call to discuss its 2019 financial results. As has been Celsion’s practice and as noted by the operator, prepared remarks will be followed by a question-and-answer period. Today’s conference call will be archived and the replay will be available beginning tomorrow through April 10, 2020 and the webcast will be available on Celsion’s website for the next 90 days.During this call, management will be making forward-looking statements regarding Celsion’s expectations and projections about future events. Generally, forward-looking statements can be identified by terminologies such as expects, anticipates, believes or other similar expressions. These statements are based on current expectations and are subject to a number of risks and uncertainties, including those set forth in the company’s periodic filings with the Securities and Exchange Commission. No forward-looking statements can be guaranteed and actual results may differ materially from such statements.I also caution that content of this conference call is accurate only as of the date of the live broadcast, March 20, 2020. Celsion undertakes no obligation to revise or update comments made during this call, except as required by law.With that said, I’d like to turn the call over to Michael Tardugno, Celsion’s Chairman, CEO and President. Michael?

Thank you, Kim, and good morning, everyone. Joining me today is Jeff Church, our Executive Vice President and Chief Financial Officer, who will provide a review of Celsion’s recent financial results in a few minutes. Also on the call for the Q&A and working from home are Dr. Nicholas Borys, our Chief Medical Officer and Dr. Khursheed Anwer, our Chief Science Officer.We will try our best to be efficient with the call even though we are operating from multiple locations and I have to say this has been marvel of technology linking up with you folks. We are communicating with remote executive by Zoom, so we see them on video. We are also on a normal conference phone and calls are dialed into the investor conference system. So I think we've got it covered from a number of directions, trying to make sure that we are prepared to answer all of your questions from the experts in the company.As always it is a pleasure to be speaking with you and it is particularly true today with so many of you working from home. And I want to start this morning with our gene-mediated immunotherapy GEN-1 and two points from our very exciting announcement that was released this morning jointly with Medidata, a world leader in clinical data management.A first point, it's clear that there is a strong trend of positive treatment effect when GEN-1 is administered intraperitoneally to ovarian cancer patients with advanced disease as compared to a virtual control group of matched patients that was provided by Medidata.Number two, a hazard ratio of 0.53 is shown in analysis when compared with synthetic data, approaching statistical significance. You'd have to agree that this is quite remarkable, but it doesn’t standalone. It is supported with impressive previously published translational and clinical…

Thank you, Mike. Details of Celsion’s full year 2019 financial results were included in the press release we issued yesterday evening and in our 10-K which we filed last night after the market closed. As Mike stated, we made significant progress during 2019 in developing our lead products. We continue to focus on efficient cash management, opportunistic and minimally deluded financings and careful attention to our cost of goods and our supply chain, all of which position us to execute our strategy and achieve our goals.As of December 31, 2019 Celsion’s cash, investments and deferred tax assets totaled $16.7 million. Subsequent to year-end we raised an additional cash proceeds of $6 million from the sale of equities including $4.4 million in net proceeds from a registered direct offering priced at the end of February. As Mike indicated earlier, we opportunistically strengthened our balance sheet to buffer against the potential for continued erosion of our share price in the face of market uncertainty.We expect to receive the $1.8 million deferred tax benefit from the sale of our New Jersey net operating losses in the second quarter of 2020. We have an additional $2 million in future tax benefits remaining under the New Jersey tax certificate transfer program that we expect to monetize later this year. Our current cash plus future planned sales of our New Jersey NOLs will extend our operating run way into mid-2021. Importantly, this is well beyond the final data readout of the OPTIMA Study which would occur likely during the first quarter of 2021.Capitalization table includes 29.3 million shares of common stock and only 3.8 million warrants which have an exercise price above our current market price. With respect to future funding flexibility, we have a 75 million shelf registration statement on file with the SEC to…

Thank you, Jeff. I hope that you can see that Celsion continues to make great progress in both of our clinical programs with the OPTIMA study now. I'm looking forward to very soon a second of two interim analyses, this interim analyses having great potential to be successful. And that GEN-1 a very important immunotherapy is showing some significant potential in ovarian cancer.Our confidence in GEN-1 is not been misplaced, as we can see from the data that we've been sharing with you over the last number of months and we look forward to continuing, if not accelerating our clinical research in ovarian cancer. And I'll just close by saying, I have always been proud of our employees and our dedication of Celsion and patient health in this time of social distancing. I'm even more proud as they continue to put patients first.So with that operator, I finished by my prepared remarks and we will open the line for questions.

Thank you. [Operator Instructions] We'll take our first question from Hartaj Singh with Oppenheimer and Company.

Good morning Hartaj.

Great, how is it going Mike, Jeff, good to hear your voice. Hey I have a couple of questions. One is, so on GEN-1 data you just published. It's good to see that the project keeps on moving along. One thing I was wondering was, when you're started comparing your lower doses to the higher doses, you have an increase in R0 resections. But the overall response rate and the PFS in these patients seems to – sorry dose response and ORR in these patients seems to stay the same. I know these are small patient numbers, but just any thoughts there?

Yes, I don't think that was unexpected, but we do expect the chemotherapy that the new adjuvant chemotherapy for these patients to be effective. But I'd like to really turn this question over to Dr. Borys. Nick?

Hi Hartaj, if I understand your question correctly, you're wondering if we've already reached a peak in terms of our response rate for the different doses.

No what I meant is, when you just look at you show the end 12 patients of the 17 patients in the two different, the lower doses and the higher doses and you're definitely getting a better R0 resection. Shouldn't the R0 section translate into better ORR, because I guess your ORRs was – you say you expected it to be approximately its 80%. So, was that just with the GEN-1 group or was that the ORR 80% in the GEN-1 plus the chemo? And then what was the ORR for the chemo alone I guess that's what I'm getting at was there a difference between the combination versus [indiscernible]?

Yes I mean I think that and interesting question and with the small numbers yes we do notice that maybe the ORR is not consistent with what we’re seeing in the R0 rate. But remember that what we’re looking at is an immunotherapy and with immunotherapy the radiology could be a little bit deceiving to what you actually see as a result in the patient. So moving for towards more long-term data looking at PFS and looking at the R0s and taking the ORR rate a little bit with the grain of salt because it’s the immunotherapy might be the best way to go for us.

Yes understood so I guess maybe if I ask the question a slightly different way which is that do you know what the ORR is for historical chemotherapy in a similar timeframe is it 80% or is it less?

I'll have to get back to you on that. But I do think off the top of my head, it's about similar to what we see historically.

Okay. And then in the Medidata analysis, the hazard ratios look very impressive. But it seems like, they're not separating out the p values are still kind of, still on the higher side. Is there any reason I mean again, these are I know small numbers, and you've got different doses there. But any thoughts there on why the hazard ratio is so impressive, and yet there seems to be a fairly broad dispersion when it comes to the p value?

Yes, I think one of the questions that the Acorn people or the Medidata people gave us right from the beginning is because these are very small numbers, that the p values we would expect not to be significant. And what we're looking for here are strong trends. And that's certainly what the hazard ratios are giving us. These numbers are just you know with 15 to 18 patients that we're looking at these numbers are really too small to expect anything in terms of a P value.Once we get into the Phase II study design, where now we have over 100 patients, I think we could see more robust results.

And [indiscernible]

I'd like to add to that Hartaj. When we looked at all they other companies who have pursued breakthrough therapy on small ends we see a similar kind of a presentation or the clinical benefit as determined by the hazard ratio appears to be quite large. So the magnitude of effect, the treatment effect appears to be quite large, but typically not enough and nor to stated with statistical confidence.

Now that’s fair Mike and again?

Not a issue.

That's fair Mike, that's fair and Borys and again, I laud you for actually showing the P value some companies might not. The other is the ThermoDox, the second interim, which we're expecting can you just walk us through if that was to be positive what would be the next steps? Just over the next sort of, let's call it three to six months and in terms of the next steps could COVID-19 throw off any of that, in your scenario plan?

Yes, let me start by answering the second question first, I don't see how – that the COVID virus would impact our plans going forward, assuming we have a positive trial result. I mean the time associated with prepping the documentation for the NDA submissions in China, the United States and the MAA in Europe is not insignificant, although we have a very accelerated schedule.As I said earlier in my prepared comments, we've begun writing the NDA and we're using a common technical – document approach, so essentially writing the NDA and the MAA for Europe at the same time. So, the next steps we've planned out very carefully, almost in a Gantt chart like fashion.I mean, it's simply we put the agency on notice about a week before we hold the DMC meeting, that we are holding a DMC meeting and we may have some results to discuss with them. If the results are positive, the agencies on notice that they will be receiving a call from us we let them know that we have a positive trial. And that we expect unblind the study we’ll give them an opportunity to comment on that, but there's no doubt in our mind.There's no ambiguity here that a positive interim analysis would result in a successful trial recognized by all the regulatory agencies that have approved our trial. We will then immediately request a pre-NDA meeting, they usually takes about 30 days to schedule.They'll give us enough time to format the data and slice and dice all of the various scenarios from the trial results, to present to the agency in a fashion to give them confidence that we have a successful trial with clean data to move forward. Once we have the FDA comments, and of course at this point…

Great Mike, thanks. And then just last question on, kudos to Jeff for keeping on squeezing more money in a non or as little as possible in a non-dilutive sense into the company. But can you just kind of give us an idea for OVATION 2 with the number of patients that you have 130 plus, starting with the second half, how long do you expect that to run? You know, just just a rough idea. How long will the enrollment take and how long will the actual the evaluation period run on that?

It's a little more close than it was just the last quarterly conference call and that's large coronavirus issue. You know, we have initiated this study nine investigator sites, all of them, you know, are large hospitals and dealing with a number with - preparing for an influx of a number of patients. We also have 16 More sites including two in Canada, they're ready to go. I mean, they have they have their foot on the gas pedal and ready to go.When we say go, however, we know that a number of those hospitals will not start a new trial will not start a trial until this kovat 919 pandemic issue is behind them. So it's really hard to give you some solid guidance. But here's what we've been thinking that it will want once we get the thumbs up from the DSMB. will initiate the balance of the trial sites in the US and Canada. It'll bring up the 25 our expectation is that each of those sites will enroll approximately one patient every two or three months.We expected then complete enrollment, it's 118 patients added to the 12 patients who are recruited and phase one, we expect to be able to as well the maybe you can do the math Ask yourself enrollment study in about a 12 month timeframe or less. But that could be that the timeline could be influenced by the reluctance of some of these clinical trial sites to initiate a study until they're convinced that their workload is coded it workload that doesn't distract them from good quality clinical study.

Great, I thank you, Mike. I appreciate all the answers.

Thank you. Thank you very much.

We'll take our next question from Matthew Cross with Jones Trading.

Good morning Matt.

Hey guys, good morning. Thanks guys for taking a couple questions from me and congrats on the progress I guess particularly for GEN-1. So I was also kind of picking up on what Hartaj was bringing up earlier about the response rate in the ORR I suppose for the 100 mg dose. And definitely hear what you're saying as far us – patient numbers were what things look like historically. I'm glad to see the trend in R0 resections for the low dose groups is the high dose?But was also wanting to drill in a little bit on the R0 rate for – on a dose-by-dose basis. Because it looks like you reported in the first nine patients 78% R0 resection rate for the 100 mg dose, which I guess is kind of between what you saw that the 100% at the 79 and dose and 66% at the 61 milligram dose. So just trying to kind of maybe see what we're missing that gives you confidence that the 100 mg/m² doses indeed the most effective one you've studied so far and should be taken into part two of a patient two?And kind of in related follow-up to that, I guess can you kind of remind us exactly how you came to the conclusion of establishing 100 mg/m² as that carry forward dose, whether that's driven by safety or PK/PD. And if there's still some potential to continue dose escalation it’s going to confirm that dose response and the ideal regimen for part two. I know you haven't reported any DLTs thus far in dose escalation, so just trying to speculate a little bit about that?

So I want to try to answer the second question first, and then I hope Nick you've got all of that on the dose dependent R0 responses. So just the maximum dose that we're considering at this point is 100 mg/m² I don't think there's any plans to increase the dose further, although we have a meeting with our Medical Advisory Group here in the next few weeks to discuss what the next steps are for the trial and really – and much of it has to do with making sure that there are no.The meeting is to make sure that there are no interferences with starting up the study that we just talked about. So, our plans have been to halt the dose escalation or conclude dose escalation at 100 mg/m² largely for practical reasons. This is a very high volume along with DNA plasmids with a very large volume of fluent.So, our centers this becomes a very practical issue, more than a medical issue. I don't believe there are any DLTs so we've seen any DLTs with the higher dose. But with that, I'm just going to turn it over to Nick and if you need some exact numbers Nick I have the breakdown of the patients at 61, 79 and 100 mg/m² yes [indiscernible].

Thank you, Mike. I think the best answer to that question is that at our highest doses, we are consistently seeing a good R0 rate, particularly against historical controls. And from the early data that we're seeing in the OVATION 2 study, where the control group seems to be acting very much like we see in other studies. And the patients that are getting the GEN-1 are consistently getting R0 resections.Again, this is an interesting indicator for us. And it's very positive the surgeons are reporting that they feel that the patients that are getting the GEN-1 are better to resect than to clean the tumor out of them. And so, we're very encouraged by this data. So I think it's the consistent numbers of the R0 at the highest doses where we feel comfortable and moving forward with 100 mg/m² dose.And then just to reiterate what Mike was saying earlier, and what you're asking earlier yes, I can confirm the safety of the drug of GEN-1 looks very, very good. We've had no key hints of a DLT. If we wanted to, we probably could go to a higher dose, but between all the data that we're getting now.If you look at the totality of the data, looking at the R0s, looking at the safety and looking now at how it compares against this well matched synthetic control arm, it certainly means we have a strong signal of, pursuing this further with regulatory agencies and pursuing further in our Phase II study. So looking at the big picture, I think we have some pretty solid data here.

And to give you some numbers in response to your question there. So at the 61 mg dose it is two or three patients having R0, but the 79 mg dose it is five of five patients who had an R0, and then 100 mg dose at 7 of 9 patients have an R0 and that average is to an 80, I believe that's 80 or 82%.

Got it no, and I totally agree the data does look great so far. And as far as maybe not even increasing a dose, but I talked about maybe more tweaking the dose given that as you just gave us the numbers, that the – both the ORR and R0 for the 79 mg group, which was just a little bit smaller than 100 with six patients versus nine did was better on both fronts, especially I think getting five out of five on the R0s. So just was considering whether speculating a little bit about whether going back to that dose made any sense or if you really thought that the 79 mg/m² dose might perform similarly with a little or few more patients like what you saw in 100, but just kind of throwing those ideas out there?

Yes, I was just going to say tweaking – I mean, I'd have to rely on certainly on our medical advisors and Dr. Borys, but we just seem to me attempting to tweak the dose with these small numbers. We might not arrive at – any better result than we currently have.

Sure, absolutely understood. And then I guess one last one from me was just about kind of looking ahead to OVATION 2 and mPFS results. I guess I was trying to extrapolate a little bit from what we're now seeing that you are released today, the PFS compared to synthetic control arm. So you've stayed for part two of OVATION 2 that the hazard ratio required that you need to see a 33% improvement in PFS so that you're aiming to see for the primary endpoints?And I just wanted to confirm whether that would translate to a 0.75 hazard ratio. And if this would be adjusted at all, if discussions with the FDA regarding breakthrough designation and potential modifications to the control arm based on the synthetic data for Medidata, whether that would tweak in any way hazard ratio you'd be looking for success?

And what – I am going to address but and of course, what we rely on is the P value, really so the I mean if we change the significance at a lower number than we've essentially had a successful trial. But I just to your first point, I take some liberties, some layman liberties with interpreting hazard ratios when I say a 33% improvement.t is I mean a hazard ratio of 0.75 although I get scolded occasionally by Dr. Borys that is a liberal translation 33% is a liberal translation of 75% hazard ratio. But it's easier for me and sometimes for other people to understand. So Nick, if you have anything you want to add to that?

Yes, thanks Mike. And I think that's a great question. We just saw the data on the synthetic control arm just a few days ago. So we're still digesting it. So I think you had made some great points. Will there be – and I think where you're going with that question is will there be some adjustments maybe to our study number, because this data from the synthetic control arm is so exciting I would say maybe.And I would just say, keep on watching this channel, because we'll have – we hope to have discussions with the FDA. See how they feel the impact of the synthetic data is on our assumptions. And also as you know we'll be reporting quite regularly on the findings of our Phase II data because it's open label. And so, there might be some adjustments because of this exciting data. And we look forward to discussions with regulatory authorities.

Yes no I’ll add to that – I'd like also to add to that – it is our intention, as I mentioned in my prepared remarks, is to review these data with the agency is a follow up that they encouraged us to have in our earlier discussion on Breakthrough designation. The goal of the meeting is really twofold is one is, do we qualify for a designation like that. I would hope that we do I mean, I think this data is quite compelling. But the second part of it is, and assuming we do as how can we accelerate this program and we have a number of thoughts on how to do that and you may have asked a question about one area where we could conceivably reduce the time to get a positive result in this Phase II study.

Got it no, I appreciate all of that input. And I hope for the best with the regulators and those discussions. Hopefully they see the data as positively as I think we all do. Thanks, guys.

And I just you know before I go to the next question, all right. So we’re in – so pretty new territory here, we think very exciting territory using a synthetic control arm as a basis to compare the treatment effect of something like GEN-1 it's been discussed for a long time. It's not novel among the theoreticians who discuss innovation in clinical trials. But we have a very good opportunity here to break some new ground. And I think given the posture that the agencies taken recently, I expect that – we’ll have a very productive discussion. So yes, operator we can go on to the next question.

We'll take our next question from Jason Kolbert with Dawson James.

Hi, guys I know it’s almost an hour, so I'll keep this brief. I just wanted to go through the 128 versus 158 deaths that you saw on the first interim versus the second. So I can really pin down the timing of when we're going to see that data? Thanks.

Yes, so we are on the cusp of reaching the threshold for the second interim analysis case. In fact we are attempting, we had special firm the DMC meeting, but because two of our DMC members are not U.S. residents one is in Barcelona is the author of the Barcelona clinic criteria for evaluating and treating liver cancer patients that's Professor Llovet. He's in Barcelona and the other one – one other I’d say well, highly regarded clinical researcher in liver cancers in Toronto.So Nick has been dealing with their schedules. And so, we expect frankly to have this DMC meeting around the first week of July, and we got to put all the start all the I's and cross all the T's but that's when we expect to have it. I am very confident we'll have enough events to hold a successful meeting at that point. Did that answer your question?

[Operator Instructions] We'll take our next question from Kumaraguru Raja with Brookline Capital Markets.

Good morning, and thanks for taking my question. I would like to further explore with regard to the synthetic control data. What would be the expected timeline in terms of communicating this with the FDA? And further in terms of the OVATION 2 trial, do you think how it is going to impact is there a possibility to include more synthetic control patient control or do you think there will be some reduction in the GEN-1 treated patients there?

Yes, so I would – let me answer your first question, the timing for discussing this with the agency. There's a bit of a protocol here – with many companies requesting breakthrough designation, the agency has set up a screening committee. That screening committee is the group that we met within our first discussion.I think we’re just top of my head, we have to provide them with our white paper request its small document, relatively small document, but we have to provide them with the request and expect to get a response from them within 30 days of receiving the document. We're going to go to work right away here, once we've digested all this data Kumar, and put together our white paper request and submitted to the agency just as soon as possible.I can't give you an exact date, but I would guess it wouldn't be more than a couple of weeks. So given that we would expect a response from the agency if we were to start the clock now is probably about six weeks. There are numerous benefits that accrue to a company that receives the breakthrough designation. That as we see it, I mean the opportunity for us to discuss a variety of strategies for accelerating the trial is.I mean, first and foremost on our list, conducting clinical research for us includes not only the overhead, but also the direct costs associated with treating patients. So the shorter the timeline financially better off for the company, of course, for the medical community, we get results sooner. So that's an objective. Apart of that our ability to be able to shorten the timeline would be FDA agreement that we can include patients from this synthetic database as a part of our control arm.I think we've talked about it internally, we don't think it would be wise to replace one for one all of the patients that would organically recruit into the control. We've talked about a 50/50 split, the goal of which would be not only we'd have a control on a control, if you would we’re half of the control arm patients would be the synthetic control arm patients, the other half are organically recruited.Give us some confidence that the results that we're seeing are not coming are true. We're looking for the truth. So that would – that's one way to reduce the time and the cost. And obviously the cost for a virtual patient is less than a cost for an organically recruited and treated patient. And every this is our timeline. So that would be one of many of our objectives in discussing this very encouraging result that we announced today.

Okay, thanks.

Thank you.

And we have no more questions in the queue at this time.

Okay well, we ran over a little bit, but I think it was all worthwhile. Thank you and our thanks to our analysts for the questions. We really do appreciate it. We hope we've clarified your concerns and provided some additional guidance. We're very excited I can say without question. The GEN-1 program is now added some additional validation to what we've been seeing all along. Along with the translation data that we've generated from our first Phase Ib study, I think is unambiguous.There's no doubt that the mechanism for GEN-1 works and that the immune system all of the – virtually all of the elements to the immune system have been recruited in a way and to modify the tumor microenvironment to pro-immune. They chain the support in some dose dependent analysis, they seem to support an improvement in clinical benefits. And now there's been some concern about that. But now, so with the comparison to the synthetic control arm, we are become extremely confident.We think this is a breakthrough for our development program and we're looking forward to reviewing it with the agency and presenting it to the investment community in more detail as we digest it. That being said we are and we are excited that this year could be an extraordinary year for the company. As I said, we're planning very early in July for our second interim analysis, the threshold for success suggests to us and the maturity of the patients on the study suggests to us that we have every chance of being successful with a blockbuster therapeutic for primary liver cancer.All that being said, the prospects that we have, can make a huge difference in the lives of cancer patients and we look forward to our work in that area. On a personal note, I want to thank you all very much, please stay safe and as I tell everybody in this difficult time period be kind of one another. So that will conclude our call operator.

This concludes today's call. Thank you for your participation. You may now disconnect.
