Greetings. And welcome to the Inovio First Quarter 2018 Financial Results Conference Call. At this time, all participants are in a listen-only mode. A brief question-and-answer session will follow the formal presentation. [Operator Instructions] As a reminder, this conference is being recorded. I would now like to turn the conference over to your host, Ben Matone. Thank you. Mr. Matone, you may begin.

Thank you, operator. Good afternoon everyone and thank you for joining us today. This call is also being webcast live on our website, ir.inovio.com and a replay will be available as indicated in our press release. As a reminder, we will be making forward looking statements during this call that relate to our business which include our plans to develop our ASPIRE immunotherapy platform in combination with our proprietary CELLECTRA delivery devices as well as our capital resources, all of which involve certain assumptions, risks, and uncertainties and could cause actual results to differ materially from these statements. These statements are based on the beliefs and expectations of management as of today. Our actual results may differ materially from our expectations. Investors should read carefully the risks and certainties described in today’s press release as well as the risk factors included in our filings with the SEC. We assume no obligation to revise or update forward-looking statements, whether as a result of new information, future events, or otherwise. Joining us on the call from Inovio are Dr. Joseph Kim, President and CEO; Peter Kies, Chief Financial Officer. I would now like to turn the call over to Inovio's President and CEO, Dr. Joseph Kim.

Thank you, Ben and thank you for everyone for joining us in our first quarter 2018 earnings conference call. Inovio remains focused on becoming the leader for treating all major HPV caused diseases from precancerous to cancerous. To-date, Inovio's evaluating VGX-3100 in a Phase III trials treating cervical precancer as well as a Phase II trial for HPV caused vulvar precancer and HPV caused head and neck cancer is being targeted in a Phase II trial conducted by MedImmune with MEDI0457, which stems from our outlicensing deal that we announced back in 2015. Our plans to add Phase II study for treating anal dysplasia to our HPV treatment platform in 2018 continue to highlight and complement both the versatility and capabilities of the ASPIRE technology platform as it relates to treating HPV caused diseases. We began this year by amending our collaboration agreement with ApolloBio, which we later closed in March, providing ApolloBio with exclusive rights to develop, manufacture, and commercialize VGX-3100 to treat precancerous caused by HPV within Greater China. Inovio received an upfront payment of $23 million, minus Chinese government taxes and we remained entitled to receive potential future milestone payments of up to $20 million as well as to receive several digits here royalty payments on sales. The agreement with ApolloBio is a significant advancement for our company as Inovio continues to identify opportunities that expand and strengthen our efforts to develop VGX-3100 globally. And just as importantly, as HPV remains the most common sexually transmitted infection in the world and the main cause of cervical cancer which kills more than 270,000 women every year worldwide, this is very important. This agreement also -- will also help broaden awareness globally on all HPV-related diseases. So, looking ahead in terms of next steps with ApolloBio, Inovio will rely…

Thanks Joseph and good afternoon everyone. Total revenue for the first quarter was $1.5 million for the three months ended March 31st, 2018 compared to $10.4 million for the same period in 2017. The decrease in comparable revenue for the first quarter compared to a year ago was primarily due to the revenue recognized from the termination payment received from Roche during the first quarter 2017 of $4 million. The decrease was also due to a decrease in grant funding recognized from our DARPA Ebola grant of $4.7 million. This was partially offset by an increase in grant funding recognized from our Zika virus sub-grant of $1.2 million. As a result of the adoption of the accounting standard update number 2014-09, revenue from contracts with customers, beginning in January 2018, all contributions received from the current grant agreements have been recorded as a contra-expense as opposed to revenue on a consolidated statement of operations. For the three months ended March 31st, 2018, $2.2 million was recorded as a contra-research and development expense, which would have been classified as revenue in the prior year. Has this changed in presentation not occurred, total revenue would have been $3.7 million for the three months ended March 31st, 2018, compared to $10.4 million for the same period in 2017. Additionally, operating expenses would have been $36.5 million compared to $32.3 million for the period -- for the prior year period. Net loss attributed to common stock holders for the quarter ended March 31st, 2018, was $32.4 million or $0.36 per share on a basic share basis compared to $23.1 million or $0.31 per share for the quarter ended March 31st, 2017. Research and development expenses for the three months ended March 31st, 2018, were $24.6 million compared to $24.5 million for the same period…

All right. Thanks Peter. As you can see, our financial position is on solid ground. Before we open the line for Q&A, it's important to recognize of both what we have accomplished during the first quarter and where we are on positioning ourselves to deliver and execute over the next 12 to 18 months. First, we are extremely pleased with our latest partnerships that have enabled us to form both a global presence and market awareness towards the adaptability of our ASPIRE platform, while providing non-dilutive funding that continues to fuel our very prolific R&D programs to bring novel therapies to clinic. Second, our latest accomplishments further validate our best ASPIRE immunotherapy technology while combining the DNA immunotherapy with our wholly-owned CELLECTRA delivery devices on targeting both precancerous and cancerous and Phase III and multiple Phase II studies, along with emerging infectious disease vaccines. Demonstration of the value of such platform and pipelines, we believe, will continue in the forms of more clinical data, partnerships, and non-dilutive funding in the coming quarters. As I mentioned before, we have broad sets of catalysts over the next 12 to 18 months that we're very excited about at Inovio. And I feel we have positioned ourselves appropriately to be the global leader for treating all major HPV-related diseases. I'll now look forward to taking your questions and discussing our progress in greater depth. Operator, please open the line for questions.

Thank you. We will now be conducting a question-and-answer session. [Operator Instructions] Our first question comes from the line of Greg Renza from RBC. Please proceed with your question.

Hey guys. Thanks for taking the question and congrats on the progress.

Thank you, Greg.

I just want to start more near term. With respect to ASCO, just you mentioned 5150 and others, just wanted to get a sense of what we could be looking for with regards to some of the titles that have been posted that are certainly relevant to you and Inovio?

Yes. So, we have two posters, along with MedImmune and MEDI0457. One is a Phase I study monotherapy that we did in cervical cancer. So, there will be a new data set that we're presenting, which shows safety and immune responses in this cancer population. Second is MedImmune's Phase II trial early design. So, they're both relevant to MEDI0457. Our third poster at ASCO is a more complete set of strong immune data from our prostate cancer, 5150, along with some of the early signals of efficacy from this study. So, we're very excited about those three poster presentations and -- because of embargo, I don't want to say anymore, but I look forward to following post-ASCO.

Of course, that helps. Thank you. And then just turning to REVEAL 1, and I certainly recognize that even Kim did not to give sort of the play-by-play as far as how that is progressing. But I just want to get your thoughts on the pacing. If I recall back in March, I think some of the sites were 50 U.S. and 10 ex U.S. I'm seeing an even split of perhaps 60, I think is what you've just recently indicated globally. So, I just want to get a sense of how that pacing has progressed in the more recent past? And how you see that perhaps replicating or certainly amplifying out thereafter to get to your ultimate goal of full capacity?

Yes. Thank you. Early in the year or last year, we -- in the beginning of the study, we started, obviously, with the U.S. sites first, and then we started to add on the ex U.S. sites. And it's a dynamic situation where the sites are not producing or performing as we have in our internal metrics, we close them down. So, we don't maintain the non-performing sites. So, there's two dynamic force of adding additional ex-U.S. sites in Europe and Asia as well as optimizing the sites in the U.S.

Got it. Thanks. And then just more holistically, what do you see as the biggest risk or risks to delivering this a successful study here both on time and with the successful outcome of delivery?

So, you're referring to REVEAL 1 and 2?

Yes.

So, the biggest risk is not recruiting fast enough or on time. I think the design is very much similar to the Phase IIb study, which we successfully met all of the efficacy and safety endpoints. So, I feel very confident in terms of how the product is going to perform and the studies are designed. So, our team is really focused on executing, opening up the sites, right regions, right sites and just cranking out the enrollment. So, -- and obviously, when you add the ex-U.S. sites and the potential upside of adding China through our partnership with Apollo, those are exciting works. So, I think we see those as positive opportunities that can perhaps can accelerate and add to our efforts that we didn't have before in last year or even earlier. So, we're, obviously, managing all the potential risks, while adding a lot more upsides. ApolloBio relationship is beyond just cash in, it's our ability to access billion people or a huge market in terms of trials accruing patients as well as potential commercialization market going forward.

Got it. That's helpful. And just one more from me, and I'll hop back into the queue. I just noticed the mention in the press release about the GENEOS Therapeutics, a wholly-owned subsidiary, just curious have you drilled down a little bit on that about your overall plans, how to think about that as an entity? And what can be expected in terms of not just timing but also some of the potential products and technical candidates under that roof? Thank you.

Yes. Thanks Greg. So, we disclosed that we have set up this subsidiary in previous calls and previous filings, where we are doing is really setting aside the neo-antigen, which are new cancer antigens that each patient generate as his or her cancer proliferates and mutates in a personalized medicine approach. So, each product is actually for a specific patient. So, we recognized a while back that Inovio's DNA-based immunotherapy platform maybe the only appropriate -- only a few -- one of a few appropriate platform to address that in a commercially and clinically positive way. So, -- and because this business model is disparate from our current model of -- for instance, INO-5401, off the shelf, antigens -- three antigens combined that can treat all patients, we decided to carve out this exciting opportunity as a separate entity, while keeping the upside economic and ownership upside of this new entity. So, we're in the process of raising a separate investor capital dedicated to promoting and advancing GENEOS' personalized neo-antigen cancer vaccine. And we will disclose to the public as more information is available, but we expect to close the Series A funding round in 2018. And separately, we'll be building out the company, so appropriately execute on those strategies. So, please stay tuned for more information. I don't have any other publicly available information to that. But I think this is another exciting way of monetizing for our Inovio shareholders in a maximum way and going after these exciting opportunities without expanding Inovio's internal resources as much as possible. So, I see this as keeping the upside without expanding the resources. So, I see this as an extremely positive advancement, but we'll keep the public more apprise as we advance these programs further.

Thanks Joseph.

Thank you.

Our next call comes from the line of Alex Schwartz from Stifel. Please proceed with your question.

Hi, Joseph and team, congrats on the progress. I had a few questions.

Thank you, Alex.

I see the Phase II anal dysplasia trial is posted in clinicaltrials.gov, and some of the KOLs kind of, I believe, at the highest unmet need maybe here. Maybe from your perspective, what are the key elements of the trial design? And then in addition, I see the primary endpoint, is that 36 weeks? Do you have a sense of, will you able -- will you be able to look at interim data? And when might we see initial data from this trial?

So, last part of the answer -- question first. Yes, there is an open label trial. So, we'll be able to track the progress near real-time. We have an early look analysis. So, we expect to have some early efficacy data in 2019. As I said though, it's an open label study. And we do agree -- we certainly agree wholeheartedly about the anal neoplasia being a huge unmet medical need. These patients have to go through very painful and devastating surgery and they're reminded daily of their problems. And surgery is not the answer, because 50% to 60% of these cases, they have to have repeat surgeries. And sometimes, more than once a year, which I could imagine short of death, anymore discomfort disease than this. So, we agree with you. Our KOLs, our advisers agree with you and we couldn't be more excited in starting this trial. They'll be more information. We expect to start the enrollment in the second quarter, this quarter, but we received all the approvals from the FDA and IRBs to start the study. So, you should hear more about this going forward.

Okay, great. And then can you provide additional color on the recent $56 million Lassa fever and MERS award? Kind of how did this come about? And then secondly, what antigens are you targeting? And just what's your overall approach to tackling these two diseases?

Yes. So, again, last part first. We published extensively on the MERS and Lassa fever vaccines from the preclinical studies, where we actually -- so MERS spike protein and Lassa fever glycoprotein-focused vaccines. We have 100% protection in lethal challenged models and monkeys and -- as well as other species. So, it's a highly effective vaccine in preclinical settings and we published those results in the past. And how did they come about? When CEPI was created in early 2017, as a result of a convergence of thoughts from some of the world's global health leaders, including one of our Board members, Professor Adel Mahmoud, who used to be the President of MERS Vaccine; Stanley Plotkin, who's on our SAB; and Jeremy Farrar, who's Head of the Wellcome Trust. Those three gentlemen wrote a piece in The New England Journal of Medicine in 2016, really has a call to arms for doing better in global health threats, new epidemics after the experience with Ebola and Zika and other events. As a society, we should have enough resources to develop premade vaccines against known, unknowns that usually keeps these global health experts up at night. So, they put their money where their mouth is. Meaning these some of the top organizations, Gates Foundation, Wellcome Trust as well as several world governments of Norway, Japan, Germany, India, and counting, have put together a fund and created an organization called CEPI to disperse these funds, so they had an open call and their RFP or their proposal, they decided that the first three targets of known, unknown threats that can kill millions of people in the future were MERS, Lassa fever and Nipah. So, Inovio coincidently had preclinical programs already existing with great data, as I said, against MERS and Lassa. In fact, we have human clinical data from MERS vaccine in the U.S. study that I mentioned earlier. So, it became a perfect fit between CEPI and Inovio. And I think this is a great organization that will fund our programs as well as others that -- and you'll hear much more about efforts by CEPI and these other global funding organizations that can really promote the -- pudding the 21st century vaccine technology against these global threats. So, we're really happy and honored to be part of this.

Okay. Well, thank you for additional color and congrats on the progress.

Thank you.

Our next question comes from the line of Yi Chen from H.C. Wainwright and Company. Please proceed with your question.

Thank you for taking my call.

Hi.

Hi. My first question is, now that Apollo has finished the -- closed the licensing deal, have they provided you with any color regarding the development time frame of VGX-3100 in China? And also, specifically for the potential of including China in the global Phase III trial, what timeframe can we -- I mean, when can we expect some updates on that front?

The updates later. And what I can tell you is we already had the kickoff meeting last month and we have a very extensive collaboration joint development meeting. So, it's a very coordinated effort between the two groups. And obviously, they're all in and we're very happy to have them support and really carry the ball in China. As far as the -- their impact, China's impact on our REVEAL trials. I think I mentioned this before in previous calls, the REVEAL 1 and 2 trains are going to go. We're not going to wait for China to hop on, but we're hopeful that as the train progresses, there will be able to hop on and really accelerate the pace of the train. But our goal is to have China become one of our sites -- and country and sites for our current Phase III study. But we are not going to wait to -- for that. So, we're working very hard to coordinate, so that they can hop on without us slowing down. So, otherwise, obviously, the China development plan can be independent of the REVEAL studies that we have ongoing. So, we're still at the early stage and we're working very closely with ApolloBio team in concert to make this happen.

Okay. Thank you. And my second question is, for INO-5401, the two Phase I/IIa trials in bladder cancer and brain cancer, if you reported positive results from these three trials in 2019, will Inovio proceed with the following Phase IIb trial? Or is there any possibility that Genentech and Regeneron could take over for future development?

So, quick answer is, we could have partners work with us. Remember -- but it really depends on the data and obviously assuming the positive efficacy readout scenario, then, I think, the possibility is unlimited. So, -- because just to remind everyone, INO-5401 would only be potentially effective against GBM and bladder. If we can demonstrate that in those two ends of the spectrum of immune-responsive cancers, these antigens, hTERT, WT1 and PSMA are expressed in multiple other cancer types. So, we would look to develop this against colorectal cancer, breast cancer, lung cancer to name a few, along with bladder and GBM. So, we could have potential partnerships with Regeneron, Genentech or Merck or BMS for that matter. So, really, we have positioned the studies to be able to give us those upsides and flexibilities, while working with some of the top partners, like Regeneron and Genentech, to help us to get there. So, I think we can have our cake in either two. And obviously, if both of these studies show positive signals and efficacy, we'll be very happy and so would our shareholders.

Thank you. And my last question is for PENNVAX-GP. Can we expect to see additional data from PENNVAX-GP during the rest of 2018? And would that be in the scenario of preventive or therapeutic use?

So, -- again, quick answer is yes, and next week. So, I guess you weren't listening to my prepared remarks, but just kidding. I said the -- this study results complete set of long-term data was selected as a plenary presentation at the Annual HVTN Conference in D.C. So, there will be more data. Also -- this is all in a preventive setting. And as I mentioned in previous calls, we also have a second therapeutic study that's going to get going this quarter, fully funded by NIH funding that will take PENNVAX-GP and treat HIV-infected individuals who are well-controlled with drugs. Our goal is to combine PENNVAX with PD-1 checkpoint inhibitor along with drugs to perhaps a possibility of looking at the clearance of the virus from their viral reservoir, so hideaway locations to bring about function of cure. I mean, I just have to add that. This is a very lofty and high upside goal. But we're in the position to use NIH funding with Dr. Steven Deeks of UCSF as a PI to go after this high-risk, high-benefit approach. But PENNVAX-GP will have its own development path as a preventive vaccine with stellar data that we've gotten thus far from our HVTN study, and we also expect or hopeful to see positive outcome from our therapeutic study that will start in the second quarter of this year.

Thank you.

Thanks Yi.

Our next question comes from the line of Joel Beatty from Citi. Please proceed with your question.

This is Sean calling in for Joel. Thanks for taking my questions and congratulations on all of your progress.

Thanks.

Can you talk briefly on VGX-3100 and how it could be used in a real-world setting? Do you kind of envisioned it being exquisitely as a monotherapy or are there opportunities to be used in a combination setting?

So, primarily, we see this as a monotherapy, as a first in line treatment for cervical dysplasia. Women who have high-grade dysplasia are sent to three stages. So, we can treat the regression -- we can bring about the regression of the lesions as well as potentially the clearance of the virus. And that's a very exciting outcome and help these patients avoid surgery that can negatively affect their cervical competence for having future babies. So, that's how we envision to be using. For VIN and AIN indications, obviously, we'll also look to be the go-to-treatment option prior to surgery. And for all these indications, it will be the first nonsurgical therapy to be approved if we're successful in doing so.

Thank you. That's very helpful. And then just sort of a brief follow-up to the previous question in the PENNVAX-GP therapeutic setting, can you talk briefly on that trial design and what the potential endpoints could be?

Yes. I mean, the primary endpoints are safety and immunogenicity of the vaccine, along with the usage of the PD-1 inhibitor, and then their secondary endpoints look at the clearance of the viral transcripts in the reservoirs. The greatest challenge for HIV -- treating HIV-infected patients has been from day one is, no one is ever cured. And the people and doctors have thrown tons of higher dose drugs, more combination of drugs and those have not resulted in the clearance of the virus. So, other than the Berlin patient who became cure, "through a bone marrow transplant," there has been zero patient who has been cured from active therapy. Now, our hypothesis or our thoughts are when you combine a vaccine that can generate just like our PENNVAX-GP, very strong killer CD8 positive T-cell immune response against the virus combining with the checkpoint inhibitor to free up those T cells and attack the virus where they hide out, along with the powerful drugs that can knock them out once they get out of their hiding area, maybe a great triple combination that could provide a function of cure. Now, again, I want to caution folks, we're not declaring that this is what we expect to see, but we are hopeful to see. And this is such a high-risk, high-benefit-type of approach that we're happy to be using in our NIH funding to do so. But I'm very excited about this study overall.

Thank you for all that Joseph. Appreciate it.

Thanks Sean.

We have no more questions at this time. I'd like to turn everything back to the management for any closing questions or comments.

Yes, thank you very much. As we discussed, we have a very exciting 12 to 18 months coming up, with lots of data flow from our vaccine and IO and other studies, so we expect more funding, more publications, more presentations, more partnerships, and just proper execution across all of our pipeline and platform programs. So, please -- as I said, please stay tuned. We're very excited about what's to come the rest of 2018 and beyond. Thank you very much.

This concludes today's teleconference. You may disconnect your lines at this time. Thank you for your participation.
