Thank you for attention and with that I would now like to turn the call over to Joseph.

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

Thank you, Ben, and good afternoon everyone. Thank you for joining us on the call today. INOVIO had a productive first quarter with developments across multiple clinical programs continuing to demonstrate the differentiating value and broad applicability of our DNA medicines platform. Please see the press release we just issued less than an hour ago for first quarter financial results and an extensive list of corporate highlights. I’m going to keep our prepared remarks brief, so that we have plenty of time to address your questions. But before we delve into updates for each therapeutic program, I want to first provide an update on the impact of the COVID-19 pandemic, on our programs and progress. First, recognizing the importance of patient safety and adhering to the global state at home government orders during the COVID-19 pandemic, our clinical operations and development teams have gone to great lengths to ensure patients participating in our clinical programs continue to be able to receive our DNA medicines and vaccines within a safe environment. I personally cannot thank them enough for their dedication and focus during these challenging times.

While we do not anticipate, while we do anticipate various impacts on every clinical trial, as a result of the COVID-19 pandemic, as of today, are clinical catalysts for 2020 that we outlined at the beginning of this year, remain on track. Beyond 2020, it is still difficult to clearly project the exact impact the continuing COVID-19 pandemic will have on our clinical development programs. That said, we do anticipate that the enrollment rate for reveal two which has been at about 50% for the month of March to April, during the pandemic lockdown were likely impact revealed to timeline Prakash will speak to this during his remarks on VGS 3100, but at this time, we are not changing guidance for our BLA anticipated timing and we will continue to work with the sites on REVEAL 2 accordingly to ensure both patient safety and data integrity. INOVIO remains on track and well-positioned to have 2020 to be a transformative year for the company. We remain confident that this statement will true even in the midst of this global pandemic.

Our team continues to be diligent and resourceful to ensure we are on track to deliver key data milestones in 2020, which include REVEAL 1 Phase 3 top-line efficacy data for our lead asset VGX-3100 in fourth quarter. Overall survival at 12-months data or OS12 data from INO-5401 for our GBM therapy being presented at ASCO and abstracts available this afternoon, followed by OS18 data in the fourth quarter. And you’ll hear more from Peter during his financial update, but INOVIO remains well-capitalized, having a strong balance sheet, which is essential for properly executing our product development and business objectives in the continued global uncertainty related to COVID-19. While our 200 plus employees are not working off physically side-by-side, our R&D and manufacturing teams in San Diego, are in our facilities relentlessly driving the development of our immunotherapies and vaccines, including, INO-4800, while practicing social distancing and taking all measures necessary to keep our teams safe.

Rest of our team is working remotely and seamlessly together in our share mission to urgently develop our DNA vaccine that we believe will play a significant part in addressing this global health crisis. As we highlighted in today’s press release, INOVIO has validated the speed and versatility of our DNA medicines platform by rapidly entering the clinic with our novel DNA vaccine candidate INO-4800 in the fight against COVID-19. Kate will elaborate more on this shortly, but I want to preface that our INO-4800 development effort has truly been a global and collaborative one. Since we began developing a COVID-19 vaccine in January, we have been forging and expanding collaborations with government entities, and premier private funders, including the U.S. Department of Defense, CEPI, and The Bill & Melinda Gates Foundation. INOVIO is collaborating with leading labs around the world to test the vaccine. And it’s working with a team of existing and new contract manufacturers to scale up the manufacturing capacities.

These relationships have helped INOVIO expedite vaccine development, access untapped resources, and prepare to massively scale up our device and plasm in the manufacturing processes to potentially create hundreds of millions of INO-4800 doses to satisfy the urgent global demand for a safe and effective vaccine. We plan to update you in more detail in the coming months. To speak more on our infectious disease experience, and where we are with INO-4800

I would now like to turn the call over to Dr. Kate Broderick. Kate?

Kate E. Broderick, Ph.D. — Senior Vice President, R&D

Thank you, Joseph and good afternoon everyone. It’s a pleasure to be here today. As Joseph expressed during his opening remarks, our team has been exceptionally productive during these exceptionally challenging times. And I’m so honored to be working with such a brilliant and dedicated team. Our dedication alongside our infectious disease expertise and pre-existing collaboration have allowed us to be in a position to rise to this emerging public health challenge being one of the first and few companies to be initially called on to develop a vaccine. In fact, when we first embarked on this development back in January, the name COVID-19 didn’t exist, and the virus in fact was not deemed a pandemic for another five, six weeks. And yet, here we are, nearly four months later, and I’m very pleased to share with you our progress to date on our COVID-19 DNA vaccine, and what you should expect to see over the next few months. In 83 days, we went from a vaccine design to first human dosing that is a remarkable speed.

On last month, we completed the first of two-doses on all 40 healthy volunteers in our Phase 1 clinical study with INO-4800 against COVID-19 disease. For the Phase 1 study, we enrolled at sites at the University of Pennsylvania, and a clinic in Kansas City, Missouri. As of today, we are on track for all 40 volunteers to complete the second rounds of dosing by the last week of May, after which we expect to have preliminary safety and immunogenicity data by late June in support of advancing rapidly to our Phase 2, 3 efficacy trial, which is planned to potentially initiate in the July, August time frame in frontline health care workers in multiple major medical centers in the U.S. Concurrently, we also expect our partners Advaccine and IVI to initiate two separate Phase 1 clinical trials of INO-4800 this summer in China and South Korea respectively. Speaking of our previous MERS vaccine work, we will be presenting you positive data from our Phase 1/2 a trial, providing a great foundation for the current COVID-19 work at the American Society of Gene & Cell Therapy Conference this week.

As already published in the conference abstract For the study participants receiving the point six Meg’s of iron or 4700 intradermal with a selector device 88% demonstrated zero conversion after two dose regime zero in eight weeks, while those receiving a three dose regime giving zero for 12 weeks 84% Cyril converted after two doses, and 100% after three doses, as measured by a binding antibody assay against the full website protein. Additionally, 92% of the vaccine recipients in both groups displays the ability to neutralize the virus using a neutralization assay. Robust T cell responses were observed in 60% of the vaccine recipients after the two-dose regimen and 84% of those in the three-dose group. Interestingly, after a single dose 0.6 mg of INO-4700 intradermal vaccination resulted in 74% binding antibody response rate and 48% neutralizing antibody response rate. We have designed our COVID-19 vaccine INO-4800 using the same strategy as we did for INO-4700, including the selection of the full length Spike protein as the target and the use of intradermal CELLECTRA delivery device. We are both hopeful and optimistic that the ongoing Phase 1 clinical trial with INO-4800 would generate a similar level of clinical immune responses and safety data as we have just reported for INO-4700.

Furthermore, this latest data demonstrated both the power of the intradermal delivery and the strength of our coronavirus experience. Furthermore, I’m really proud to say that while INOVIO has been able to bring a new vaccine from construct design to Phase 1 clinical trials in record times, we were still able to confirm the robust immune responses of INO-4800 in multiple animal models that we typically test all our vaccine candidates, including small animals, all the way up to non-human primate. In fact, our preclinical data has been accepted for a peer reviewed publication in nature communication, demonstrating robust T and antibody responses, including neutralization antibody responses in several animal models with INO-4800 vaccination. Over the next couple of months, we will also expect to attain and report data from several animal challenge studies being conducted collaboratively at some of the world’s leading laboratories. Leveraging these pre-clinical results, and continued work with our animal challenge studies along with our expected Phase 1 data in June, we anticipate having the necessary immune response and safety data to support our clients to move into a large randomized Phase 2/3 efficacy study.

And finally, another important advantage of INOVIO’s platform technology I wanted to speak here is that our DNA vaccines do not require the challenging deep frozen coaching storage. In fact, our vaccines are stable at room temperature for at least one-year and for five years at two-degrees to eight-degrees Celsius, which of course is normal refrigeration temperature. In comparison, most messenger RNA and vital vectors vaccines are not temperature sensitive – stable and are often have to be maintained in a freezer cold chamber as low as minus 80 degrees Celsius. This is an important differentiator and key advantage of INOVIO DNA vaccine.

And with that, I’ll now turn it back over to you, Joseph. Thank you.

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

Thank you, Kate. Appreciate that update. Really amazing work. Again, I can’t thank you and the team enough for all the dedication and hard work that you have been doing in the midst of this pandemic. To reiterate, we are aiming to be in a Phase 2/3 efficacy study by the July, August timeframe, where we will be targeting healthcare workers on the frontline. We estimate the high side of the study size to be around 2,000 healthcare workers and our capable regulatory and clinical operations teams are confident that we could fully enroll this number of participants in about one-month. Again, the actual size of the study will largely depend on the infection rate at that time. In addition to our plan to determine the true efficacy of our vaccine and a large well designed randomized Phase 2/3 study we’re also planning to pursue the emergency use authorization task to achieve emergency approval of INO-4800. We plan to utilize immunogenicity, and safety data from our Phase 1 trial, as well as from an early subset of Phase 2/3 participants, along with our anticipated pre-clinical efficacy data from our ongoing animal challenge studies to form our EUA submission being planned for potentially fourth quarter of this year.

Now, let’s move our update to our mid and late stage clinical programs. In fact, in less than 48 hours from now, the overall survival with 12 months data for I know 50 for one immunotherapy in 52. newly diagnosed GBM patients study will be available to the public, as our abstract has been accepted for presentation at ASCO. abstracts will be available this Wednesday at five pm followed by a virtual presentation at the end of this month. We had previously presented very exciting progression free survival at six months in the study last winter. So, naturally I know you are all really excited to see this early promising data fully translate to the OS12 data. You will not have to wait too long for this data. Before I turn the call over to Prakash for an update on VGX- 3100, I want to provide a brief update on INO-3107, which targets the rare orphan HPV associated disease, RRP or recurrent respiratory papillomatosis. Given the progressive nature of this rare debilitating and potentially life threatening disease, patients are eager for an alternative treatment so they can avoid repeated invasive surgery.

As we stated in our last call, the FDA accepted INOVIO IND application to valuate INO-3107 in a Phase 1/2 trial for the treatment of RRP. We expect to enroll approximately 63 patients in this Phase 1/2 trial to evaluate the efficacy, safety, tolerability, and immunogenicity of INO-3107 in patients with high-risk HPV-6 and/or 11 associated RRP who have needed at least two surgeries annually for the last three years or to remove the papilloma tumors. While the COVID-19 pandemic has thrown a curveball at this trial, we anticipate to begin dosing patients this summer. So, we have so much to look forward to this summer on top of our progress in INO-4800.

Now, I like to turn over the call to Dr. Prakash Bhuyan, MD PhD, who will provide an update on multiple targets and studies we have ongoing for VGX-3100. Prakash?

Prakash Bhuyan, M.D., Ph.D. — Vice President, Clinical Development

Thank you, Joseph, and hello, everyone. As you know, our lead asset is VGX-3100, which targets HPV associated diseases. Despite the negative impact of COVID-19 upon our clinical programs, we still plan to report top line efficacy data from REVEAL 1, which is our pivotal Phase 3 trial or HPV related high grade cervical dysplasia patient patients, and that’ll be in the fourth quarter of this year. For REVEAL 2 recruitment is still underway at our sites around the world, and the COVID-19 pandemic has certainly had an impact upon our patient recruitment since March. We are hopeful in getting back to the pre-pandemic rates as soon as possible as various countries and regions begin to open back up. As a reminder, REVEAL 2 has the same design and target patient enrollment of 198 subjects as in REVEAL 1 main difference is the safety follow-up time of one-month for REVEAL 2 versus one-year for REVEAL 1.

Turning now to our positive interim data that we’ve reported in March, at ASCCP, we continue to validate the broader applicability of VGX-3100 and our HPV platform in general. So, specifically, in our Phase 2 trial and anal dysplasia, we’ve reported that of the 20 patients with data available. 50% showed clearance of their HPV 16, 18 positive precancerous lesions, and 75% of the subjects showed a reduction in the HPV 16, 18 positive precancerous lesion number; just six months after the first-dose. We do believe these data are extremely encouraging. Not only do they build upon the previously reported efficacy in our cervical dysplasia Phase 2b trial, but as further contact to this only one in five people with HPV 16 associated precancerous dysplasia would be expected to exhibit spontaneous resolution at one-year without adequate treatment, precancerous anal dysplasia with typically progressed to anal cancer. Having a DNA medicine that can clear these lesions without the burden of repetitive, multiple and painful surgical or invasive treatments would change the standard of care and provide patients with a true meaningful benefit.

Demonstrating VGX-3100’s broad applicability we also reported encouraging Phase 2 initial data in our vulvar dysplasia trial where 12 of the 22 subjects completed their primary endpoint evaluation at six months following the treatment with VGX-3100. The results were shared at ASCCP in March, and demonstrated that 80% of treated women had an overall decrease in the lesion area six months after treatment. Two trial subjects completely resolved their HPV 16 vulvar dysplasia and to put this into context spontaneous regression for these patients is expected to be very low, about 2% to 5% and typically takes one-years to two years. So taken together these data build the case for VGX-3100s broader potential to treat HPV caused pre-cancers and further proof-of-concept for our DNA medicine approach. We look forward to providing full study results for both the vulvar and anal precancerous dysplasia trial later this year.

And with that, I’ll turn it back over to you Joseph.

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

Great, thank you, Prakash. Running a large global Phase 3 study is challenging enough, and working in the wake of a pandemic is unprecedented. You and your team have been truly Rock Star through all this, showing your tireless dedication to work on providing a therapeutic alternative to surgery and improve the quality of life for these patients. Thank you again.

Now, I will ask our CFO, Peter Kies, to provide a financial update. Peter?

Peter Kies — Chief Financial Officer

Thanks, Joseph and good afternoon everyone. First, I will provide a summary of our capital resources for the first quarter of 2020. The company ended with 270 million in cash, cash equivalents, and short-term investments as of March 31, 2020. To this cash position, we added an additional 121.7 million through the ATM in April. Given the uncertainties associated with the macro impact that the pandemic may have on the global economy, we have been both prudent and proactive in maintaining a strong financial position, providing INOVIO with multi-years worth of cash runway. As both Kate and Joseph mentioned during their prepared remarks, the company anticipates to continue to receive external funding to support INOVIO’s advancement of INO-4800. Turning now to revenue and net income, or net loss in our case, we reported total revenue of 1.3 million for the three months ended March 31, 2020. INOVIO’s net loss for the quarter ended March 31, 2020 was 32.5 million or $0.26 per share basic and dilutive.

Lastly, R&D expenses for the three months ended March 31, 2020 were 19.1 million, compared to 24.4 million for the same period in 2019. The decrease in R&D expenses was primarily related to a decrease in employee compensation expenses due to lower employee headcount, accompanied by a decrease in clinical trial expense timing, and there was an increase in our contra-R&D expense recorded from grant revenues. A complete summary of our financial statements for the first quarter of 2020 can be found in today’s press release and in our Form 10-K filed with the SEC. This can also be accessed on our website under investor relations financial reports.

With that, I’ll turn it back to you, Joseph. Thanks.

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

Thank you, Peter. Before we turn to the analyst Q&A, I like to list all of the events we expect before our next earnings report in August. Here are the lists. We expect to report on 12 months overall survival efficacy data from INO-5401 in GBM to be presented at ASCO in late May. Second, preliminary safety and immune responses data from our U.S. Phase 1 trial for COVID-19 vaccine INO-4800 in 40 healthy volunteers. Next, data from our COVID-19 animal challenge studies. Fourth, additional external funding to support INO-4800 development. Fifth, either started or be poised to start our large randomized Phase 2/3 efficacy trial upon regulatory approval. Sixth, start of additional clinical trial for INO-4800 in China and in South Korea. seven steps of patient dosing for Phase 1/2 clinical trial of INO-3107 to treat RRP; lot of milestones to look forward to.

Now, I look forward to taking your questions. Operator, please open the line for the analysts.

Questions and Answers:

Operator

Thank you. [Operator Instructions] Our first question today will come from Stephen Willey with Stifel. Please proceed with your question.

Stephen Willey — Stifel — Analyst

Yes, good afternoon. Thanks for taking the question. I think, Joseph, you mentioned in your comments a couple times regarding your ability to secure external funding. I believe there was a CEPI grant handed out to a competitive program here after market hours today and you know, that’s obviously an organization that you have a pre-existing relationship with, they gave you I think 16 million for the MERS vaccine. So, I’m not sure what you can say about the funding process itself, but you know, I guess anything you can say just with respect to active dialogues you may be having, you know, whether this involves some kind of formal application process? And to what extent you know, the need to scale the devices is potentially viewed as a rate limiting step here by some of these agencies?

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

Well, thanks, Steve. Great question and I guess a great thing for Novak’s and CEPI. As I stated before, there are, you know, extensive amount of fundings available for promising vaccine candidates, as we all have seen brought our contracts to both J&J and Moderna, and now CEPI funding to Novavax. There’s probably at least $15 billion to $20 billion in total funding available in both BARDA and CEPI and the Bill & Melinda Gates Foundation each have said they will each support up to five or six for CEPI and BARDA case and both CEPI and BMGF both have stated that they will support up to eight different candidates in rapid scale up. So, I think they’re, you know, congratulations to Novavax and Moderna and J&J have already received theirs. So, I think the potential additional funding for INOVIO I think is great. I do think there will be a total of 10 to 12 viable candidate vaccines, which will be heavily invested by these various funding agencies. So, you know, as we make progress, I think the potential of INOVIO’s receiving these external funding, as we mentioned in our prepared remarks is very good.

Lastly, touching on your question about the devices, you know, we received already funding from Bill & Melinda Gates Foundation earlier this year to help accelerate our commercial vaccine device, and we’re on good track for doing that. So, I don’t believe the devices and the rates are going to be a rate limiter for us to both scale up and also receive these external fundings.

Stephen Willey — Stifel — Analyst

Okay, that’s, that’s helpful color. And, you know, you talked about the desire to pursue an emergency use authorization path, and I think maybe even reference the submission here before the end of this year. Can you maybe just talk a little bit about how that process logistically works? I believe the EUA is under the auspice of HHS, not FDA. So, what kind of submission actually needs to be made? Is that analogous to I guess, an NDA filing or how was that different I guess when you’re submitting something to an agency that’s outside of FDA?

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

Yeah, I mean, certainly the Secretary of HHS has the authority to provide EUA authorization, but of course, the FDA reports through the HHS so – as we have seen numerously in therapeutics and diagnostics case, there’s been dozens of EUAs provided for those two areas. For vaccines, there hasn’t been any, ever. So, the clarity on how and when those may occur is something that we in our team or regulatory team or clinical team are working through, but here’s what what’s been communicated to us and others publicly.

One is, the vaccine has to demonstrate some level of safety, and immune responses, and especially if you can tie those immune responses to any challenge model data, if they’re relevant. So, I think we would be at INOVIO to be in position with our Phase 1 primary data readouts in June, with multiple animal challenge studies, including non-human primates, ferrets and mice to be reported in the next couple of months, that we will be in a great position to collect those data, evaluate and prepare a proper submission to the FDA an EUA. So, you know, I think the exact mechanism and the process will be clarified in the next couple months, but we should be in a great position to apply for that.

Stephen Willey — Stifel — Analyst

Okay, I’ll hop back in the queue. Thanks.

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

Right.

Operator

Our next question will come from Chris Raymond from Piper Sandler. Please proceed with your question.

Chris Raymond — Piper Sandler — Analyst

Hi, thanks for taking the question, and congrats on all the progress during the quarter. This is Nicole Gabreski on for Chris. Maybe one, ahead of the ASCO abstracts being released this week, I guess, we just wanted to clarify the INO-5401 data, what should we expect to see in the abstract versus what will be presented? Could you just provide a little more color on that?

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

Yeah, the abstract will provide the actual percentage of our cohorts surviving at 12 months. So, thus providing an OS-12 number. Just to jog everybody’s memory, we have 52 total patients in our study. INO-5401 plus 9012 dosed together with Regeneron’s Libtayo their PD-1 checkpoint inhibitor. All the patients also received standard of care, which is comprised of surgery and chemo radiation, chemo with Temozolomide. So, we what we’re looking for – what we’re looking forward to presenting is the overall survival of our total 52 patient population at 12 months, and we will be able to compare that information OS-12 to what we would expect from extensive publications in these populations from standard of care of surgery and chemo radiation, and typically all comers, both unmethylated and methylated. The standard of care has been reported in about 65% of those populations being alive at 12 months. So, it’s a very devastating cancer, but we’re hopeful that we can present much higher than 65% in our abstract, which will be visible on Wednesday evening, this week.

Nicole Gabreski — Piper Sandler — Analyst

Great, that’s helpful. And then maybe just a second question on INO-4800, just as far as the trial design that you laid out for the Phase 2/3 today, and you know, just the target patient population and the trial size, have you talked to FDA about these details and received feedback on that at this point?

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

Well, we have interacted with the FDA in a general sense, but we expect to have a little more detail communications regarding the trial design as we finalize them. So, I’ve prepared and what I provided to disclose today, really are rough design. Of course our team is seriously working to finalize and refine in preparation with our interactions with the FDA to come.

Nicole Gabreski — Piper Sandler — Analyst

Okay, great. Thank you so much.

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

Great, thanks.

Operator

Our next question will come from Gregory Renza with RBC Capital Markets. Please proceed with your question.

Gregory Renza — RBC Capital Markets — Analyst

Hi, Joseph and team on congratulations again on all this progress. Thanks for your contribution here to the pandemic and thanks for taking the question here.

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

Yeah, thanks Greg.

Gregory Renza — RBC Capital Markets — Analyst

Joseph – yeah thank you. Just wanted to start a little bit, as you sort of talk about 4800 and its profile, mentioning, of course, the convenience with distribution, as well as the suitability or targets with healthcare workers going after in the next trial, I’m just curious if you could discuss a little bit about the suitability of this asset, what makes it perhaps different from the others, and should we be thinking of particular either geographies or patient populations that would perhaps get 4800 a particular edge, especially in light of the fact that this can really be a multi-asset or multi-pronged approach to find a solution with a vaccine? Thank you very much.

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

Yeah, thanks, Greg. You know, just quickly, as Kate summarized the earlier, there is couple of attributes that makes INOVIO’s INO-4800 more advantageous compared to other platforms out there. One is the stability of the product. So, DNA plasmids are extremely stable. We have long-term product dating around five years with two degree to eight degree Celsius refrigerated conditions. You can leave it in the ambient temperature for over a year and not lose any potency of the vaccine. So, it’s a true advantage over most of the mRNA or viral vectors or proteins, which have to maintain frozen cold chain throughout the distribution and storage conditions. Second, major importance, major advantage that our DNA vaccines have compared to other platforms is our ability to generate both high levels of CD8 T Cell, killer T cell responses against the antigen, along with our ability to generate the neutralizing antibodies. So, we’ve demonstrated this in our nature communication publication and what I think is really important is both this balanced immune responses and CD8 T Cell responses, which is less susceptible to changes in viral antigen sequences.

So, you know, I think being able to provide both CD8 T cell response, as well as a neutralizing antibody response is something that the other platform vaccines will not have as much. Certainly, what we saw in our MERS vaccine challenge studies in non-human primates or rhesus macaques, where we saw 100% protection against the pathogenic MERS virus challenge. We saw that it was very important to have both neutralizing antibodies or binding antibodies, but also very important to have strong T cell responses. So, I think our ability to generate both T cells and antibody responses will lend us very well to perhaps immune compromised populations, maybe older, more senior populations, and perhaps other segments, as well as the general public, I think, you know, the level of the immune responses that we’ve been generating. And I can turn to Kate, for a little more details. What we are already seeing in non-human primates in terms of the antibodies and T cell responses, I think we’re very excited about that compared to the convalescent patient data that others have published in recent publications.

Kate, would you like to discuss a little bit more about our immune responses compared to the published convalescent patient data?

Kate E. Broderick, Ph.D. — Senior Vice President, R&D

Yeah, absolutely. And then one thing that I was particularly excited to see was the rapidity, and so as Joseph quite rightly mentioned, we generated really rather robust, both antibody and T cell responses, including neutralizing antibody and all of the animal models that we tested, but what was really very heartening to see was the rapidity of those responses. So, we started seeing really measurable responses really very early on and not detailed in our nature communication, and paper.

So, it’s really – that’s really quite important, especially when you’re thinking about an emerging infectious disease as we are at the moment, obviously, but as Joseph mentioned, we’ve also had access to convalescent patient Sierra. and so we’re able to do side-by-side comparisons. And it’s really – it’s very, very encouraging to see the levels that we’re seeing in the animals as very comparable to the levels that we’re seeing in the convalescent patients. So, it’s looking very promising at the moment.

That’s very helpful. Thank you very much, and just one more quick one, if I may? I know you’ve already provided some color on device strategy and progress. I’m just curious if, as you talk about one million doses by y the end of the year to have the capacity for, you know how that translates into devices, and what progress we should be looking for there, maybe more specifically, what the dose to device ratio operation like can be expected to be? Thank you.

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

Yeah, thanks, Greg. Well, just roughly when we say we’re preparing one million doses, we’re discussing – we’re stating both the plasmids and the device in a race to deliver them. So, you can’t really have one without the other. So, we’re on the right track to do that, but we’re preparing to do beyond that. We’re preparing and increasing our scale to be able to provide hundreds of millions of doses starting next year. So, these are the preparations that take to, which we’re already doing to scale up in that massive scale, assuming success of INO-4800, you know, we will be in a great position to do so by relying on our current contract manufacturers of plasmids and adding on additional manufacturers that can help us scale.

In the device side, we’ve already have both produced enough arrays and devices to meet the one million need. So, those processes are ongoing, both within our GMP facility in San Diego, as well as our additional contract, device and array manufacturers that we have brought on. So, these are very extensive efforts. You know, we’ve never had to prepare for hundreds of millions of doses if not billions of doses that might be required to combat COVID-19 globally. Prior to this year, most of our doses that we were planning for were in hundreds of thousands of doses, if at most millions of doses. So, I think this is a challenge our team has taken on. And I think we’re making a great progress in this regard.

Our next question will come from Naureen Quibria of Maxim Group. Please proceed with your question.

Naureen Quibria — Maxim Group — Analyst

Hi, congrats on all the progress and thanks for taking my questions. I guess my first one is on the GBM study, you know that you’ll be presenting on at ASCO, and we’ll get the data just in a few days. You know, you mentioned that survival data for one-year for these patients are historically 60% to 65% at one year, are you able to share with us what kind of delta you hope to see from historical rates for the 12 months OS? What would you think would be encouraging?

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

Well, what number would get you excited Naureen?

Naureen Quibria — Maxim Group — Analyst

Obviously, well higher than that.

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

That’s a great question, but yeah, I think substantive increase over 60%, 65% will be very encouraging, you know, this is not the totally finished line, we will follow these patients, at least for another six months or longer. So, we will be, I mean, we feel like this is a dataset that we’re building up. So, from a PFS6, which was very exciting, you know, between, you know, 20% to 30% difference compared to the standard of care at that early progression free number was very encouraging to us, and where we are today at overall survival at 12 months, and I think that adds to another level of validity and confidence in this data. And then as we continue to have longer tail in the survival curve in these patients at OS18, I mean, that would even be even greater feat. So, you know, what would be a great number for you? If you assume the center cares 60 to 65?

Naureen Quibria — Maxim Group — Analyst

Well, I like it – I would like it to be perfect, you know, but you know that’s…

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

That’s sort of why…

Naureen Quibria — Maxim Group — Analyst

Alright. So…

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

That number is very difficult cancer population, you know. Everyone dies in five years, right. So, and the overall survival, median survival for unmethylated population is around one year, about 13, 14 months and methylated population is around 20, 22 months. So, these are really patients who are suffering from a very deadly cancer. So, anything we can do, you know, because there hasn’t been a huge advancement in GBM therapy since temozolomide. So, if we – our 5401 plus Regeneron’s Libtayo can make an impact on this important cancer, you know, I would be really thrilled with the data. So, you know, I think you just got to stay, be stay tuned for a couple more days to see our data.

Naureen Quibria — Maxim Group — Analyst

Right. And as for, you know, you also posted positive interim data on the the folder studies, on a proportion of patients back in March, can you remind us, are those studies actually fully enrolled?

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

Yes, yes. They were fully enrolled last year. What we presented at the ASCCP and publicly disclose where the patients who crossed the six months, the actual endpoint, the timeline. So, you know, over the next couple of months, I think we will have full data set from all the patients in both Phase 2 studies. So, we will have those data available later this year.

Naureen Quibria — Maxim Group — Analyst

Okay, great. And one last one for me, this is regarding the MEDI0457 with the Durva study, actually, just last week on the clinical trials website AstraZeneca updated their head and neck study and they changed the anticipated number of patients from 40 to 35 actual patients from 40 anticipated to 35, I’m just curious, you know, is there anything we might be able to read from that, you know, do you have any thoughts on that?

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

No, we had publicly disclosed a belief last year that they had fully enrolled that 35 patients and they’re continually following these patients for survival benefits as well. So, you know, as we stated before, I still expect AstraZeneca to report the – some data this year, but we can’t really say when that may be. So, they have full control. AZ has full control over the data, and when and where to present, but we expect that to be in sometime in 2020.

Naureen Quibria — Maxim Group — Analyst

Great, okay, got it. Thank you. That’s all for me.

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

Right. Thank you.

Our next question will come from Yi Chen with H.C. Wainwright. Please proceed with your question.

Yi Chen — H.C. Wainwright — Analyst

Thank you for taking my question.

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

Hi.

Yi Chen — H.C. Wainwright — Analyst

Hi, Joseph. How many data sets are from the animal challenge studies shall we expect in coming months?

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

Yes. We have mouse challenge, well, Kate, would you like to address this? These are your studies. So…

Kate E. Broderick, Ph.D. — Senior Vice President, R&D

Yes, certainly, Joseph. Thank you. So, we really have consciously chosen to look at a wide spectrum of challenge models that includes the most challenge, the Fed at challenge and the primate challenge. And we think that’s going to give us a really broad spectrum picture of how well our vaccine is performing. We’re very confident about that. And so we’ve partnered with a really – labs all across the globe who are clearly leaders in their particular fields of challenge, and so we’re going to be getting those data as it comes out and with the most data being delivered soon as to in the next month or so…

Yi Chen — H.C. Wainwright — Analyst

Got it. Thank you. Next question, regarding the design after Phase 2/3 trial this summer, at that time, I guess there will be other COVID-19 vaccines probably being evaluating Phase 2 trials as well, do you think they will also recruit frontline healthcare workers to be enrolled in their investment trial? And if so, well, of course, these healthcare workers probably won’t be constantly exposed to COVID-19 viruses. So, how long do you plan to follow these workers after injection of the vaccine?

And also, they will likely be wearing personal protective equipment. So, I guess at the end of the trial, you will probably measure how many people actually get infected, but of those who are not getting affected, how do you know they’re getting the protection from the vaccine or they’re getting protection from the personal protective equipment?

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

Yeah, great question. So duration of follow up, obviously, will report after we get the determination with the FDA. So, you know, as it could be as long as a year, it could be about six months. You know, we look for the duration that makes sense for us. Either way, we will continue to follow up with these volunteers in a Phase 4 study if we’re successful. In terms of the vaccine efficacy, yeah, this will be a randomized double blinded study. So, we expect half the participants will get our vaccine, half our placebo. So, it will be a true randomized design, true efficacy determinating study. So, while we’re targeting, you know, why we want to do this is the healthcare frontline workers are, you know, these are our heroes and they’re day-in and day-out, even with their PPE, constantly exposed to a potential infection with the virus, so we feel that this population is the frontline population that we would want to protect first.

So, getting a true efficacy data in this setting will be highly valuable for not just our vaccine development, but overall advancement of the field as a whole, but we also feel that we have a very compelling candidate in INO-4800. So, we like to get it tested in this very challenging environment, so that we can bring the vaccine as fast as we can to these heroes and the general public as rapidly as possible. In terms of the overall performance of the vaccine, you know, I think we’ll get a very good idea by June. How well are vaccine is doing from immune responses data in all 40 healthy volunteers. And by the way, as I mentioned or Kate earlier that all of the 40 folks who bravely volunteer for this important study, their safety profile has been great thus far. They will all receive their second-dose by the end of – before the end of May.

So, we’re very excited how well that study is ongoing. And of course, our animal response data, as I mentioned, will be publicly viewable soon as that paper has been accepted through a peer review in Nature Communications. And what Kate mentioned about the challenge studies, we should have the Mouse Challenge data that’s being run in China. We have fared challenge studies ongoing in Australia, and we have non-human primate studies ongoing in England and in the U.S. So, you know, we think we have a very compelling vaccine and we hope to demonstrate not just the immunogenicity and potentially the protective ability of this vaccine, leading into our Phase 2/3 efficacy study.

Yi Chen — H.C. Wainwright — Analyst

Got it? It appeared back in the 90s that the FDA and CDER has agreed to a human challenge study for a cholera vaccine. Do you think this is necessary for COVID-19? What’s your comment?

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

I’m still very concerned about human challenge. You know, there’s been other human challenge studies for vaccines successfully done. For influenza, for RSV, and, and others. I think norovirus as well, but you know, not so much is still unknown about SARS-CoV-2 virus and COVID-19 disease. I think the risk really outweighs the potential benefit for those volunteers. So, I personally have some ethical questions that still is unresolved for us to support a human challenge study in such a new disease.

That being said, you know, I think the spirit of moving faster is something that we all prescribed to at INOVIO. And that’s why we want to get to a well -designed large efficacy trial both to demonstrate the efficacy and the true safety of our vaccine. In a way we feel really strongly that our vaccine is safe across what we have demonstrated in our previous clinical studies. And we look forward to demonstrating that in our Phase 1 study with INO4800 and upcoming Phase 2/3 trial as well in larger population.

Yi Chen — H.C. Wainwright — Analyst

Got it. My last question is on operating expenses. So, as long as the economy lockdown is still in place across the country, do you expect the R&D expenses to remain relatively low going forward?

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

R&D expenses, yeah, go ahead, Peter.

Peter Kies — Chief Financial Officer

Yeah, we expect them to remain fairly consistent. As we said before, we expect most of the 4800 expenses to be funded by external forces, and so we expect the expenses to remain fairly consistent, but we will see we did have a bonus payout that we hadn’t budgeted, so that adds a little bit more. So, we’re looking at about 80 million annually. 80, 85 net burn annually.

Yi Chen — H.C. Wainwright — Analyst

Okay, go it, thank you.

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

So with that projection, you know, our cash runway is a quiet healthy. So we feel that with uncertainty of the pandemic, you know, we have a strong financial position. We have lots of important data milestones coming up. Even without COVID-19 vaccine in GBM and REVEAL 1, but then you add in or develop a rapid development in COVID-19 vaccine, both in Phase 1 data and all other challenge results in the next couple months. You know, we really have very data full 2020 in the next several months.

Yi Chen — H.C. Wainwright — Analyst

Got it. Thank you.

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

Yes, thank you. Our next question will come from Jonathan Aschoff with ROTH Capital. Please proceed with your question.

Jonathan Aschoff — ROTH Capital — Analyst

Thank you. I was wondering earlier in your comments, did you say that REVEAL 2 was 50% enrolled or that COVID-19 is making the enrollment rate 50% of what it was before COVID-19.

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

It is latter for March and April. So, we saw a decrease in enrollment rate from prior to the pandemic level because of all of the lockdown and such stay at home orders globally.

Jonathan Aschoff — ROTH Capital — Analyst

Okay. And how much do you think will be spent in total you plus the external funding on 4800 up to the point that you know, if 4800 is clinically successful enough to seek approval?

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

Well, I mean, it depends on EUA or traditional BLA. So, EUA it could be even before we finish the Phase 2/3 trial as the efficacy is not a required element in EUA application, but you know, if we’re counting the Phase 2/3 and really a lot of the spending will be on the scale up of the manufacturing and the money spent to provide the doses. So, you know, obviously, you know, clinical trial expenses and phase one studies have already been funded through CEPI and, and others and we expect to receive additional funding for next clinical development stages, including Phase 2/3. So, you know, I think we’re going to be very well funded in support of events in INO-4800.

The next steps are to make sure that we can deliver many, many doses that is required from the society. You know, continually as more people die across the globe, especially in the United States, you know, there’s more increase and an increasing demand for a safe and effective vaccine to get to the public as soon as possible. So, we’re taking a stepwise approach. You know, taking both the EUA path where emergency approval could be granted for specific targeted population like the first responders and healthcare workers, and then getting it through – getting our clinical development plan through the randomized large well-designed efficacy trial together the true efficacy of our vaccine and the safety in large numbers in support of a BLA approval.

Jonathan Aschoff — ROTH Capital — Analyst

Joe, if it was a BLA, how much you think it would cost for that process including a million doses?

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

So potentially our next trial could be a registrational trial, Phase 2/3. If we assume that and we assume a million doses, I mean that will be in a total value of $100 million 150 million from start.

Jonathan Aschoff — ROTH Capital — Analyst

Okay.

J. Joseph Kim, Ph.D. — President, Chief Executive Officer, Director

Is that what you’re looking for or…?

Jonathan Aschoff — ROTH Capital — Analyst

Yes, yes. Totally, thank you.
