I would now like to turn the conference over to Steve Harrison, Vice President of Investor Relations. Please go ahead.

Speaker 1

Thank you, Jenny, and thank you for everyone joining us this afternoon. With me today are Doctor. Helen Sabzavari, President and CEO of Precigen Harry Tomacian, our CFO Phil Tennant, our Chief Commercial Officer and our Chief Operating Officer, Ritu Shah. Before we begin, let me briefly review our forward looking statements. During today's call, we will make various forward looking statements.

Please read the Safe Harbor statement contained in our most recent SEC filings as well as risk factors contained in Precigen's filings. With that, I would like to now turn the call over to Doctor. Sabzavari. Helen?

Speaker 2

Thank you, Steve, and thank you to all joining us today. It is a pivotal time at Precigen as we work hard to get what could be the 1st FDA approved treatment for the devastating recurring respiratory papillomatosis disease or as we know as RRP to the market. What I would like to do at the beginning is take you through some of the key program and business highlights and then go through some of our strategic prioritization that has been communicated recently. Let me start by talking about PRGN 2012, which is the focus now of our portfolio. As you know, PRGN 2012 is our adenovirus gene therapy that is designed to elicit immune responses directed to HPV 611 infected tumors.

Speaker 2

And to raise the immune system to both of these epitopes, both HPV 6 and 11 for the treatment of recurrent respiratory papillomatosis. Let's establish some of the facts upfront in regard to our PRGN 2012. As I mentioned, it's delivered by our gorilla adenovectors, and it's a gene therapy. It's delivered subcutaneously. It does not require any kind of a device.

Speaker 2

So it's an ease of administration that can be done at any office setting, for instance. The second important part of this gene therapy treatment is that our gorilla adenovirus platform in general and the viral vector that is used for delivery of PRGN2012 is differentiated from other viral vectors. Even though there is this perception that all viral vectors are similar and therefore they can be given a very limited number of time, perhaps only once or twice, and they cannot be used in redosing because humans have pre immunity to them. This is not applying to the gorilla adenoviruses. And why do I say that?

Speaker 2

Simply humans either have 0 pre immunity or very little pre immunity to these vectors. And by the way, these vectors are designed in such a way that elicit a high affinity C cell and they push toward the CDA responses. And therefore, in a number of clinical trials that we have done across various indications, we have shown over a period of time, you can keep redosing with these vectors and keep enhancement the immune responses and especially high affinity CD8 T cell responses. So I just wanted to clarify that fact. This is one of the differentiating factors of our gorilla adenovirus platform in general compared to other AAV and viral delivery factors.

Speaker 2

And also these guvella adenoviruses allows us to have a high payload that can we can put many epitopes and many genes. And therefore, when I say that we are targeting HPV-six and eleven and raise immune responses to both, we have shown that and we have shown that in the clinical trial. Now with that in mind, what have we done with the PRGN-twenty 12? As you are well aware in the PRGN 2012 is the 1st drug ever received a breakthrough designation and accelerated path from FDA in June of 2023. And with that designation, we also had received the orphan drug designation from the FDA as well as EMA.

Speaker 2

The interesting part of this was that because we had designed our clinical trial in such a way that, first of all, address the most advanced patient and most patients with the highest number of surgeries And also, it already put a very robust endpoint, not just reduction in the number of surgery, but actually having safety and efficacy that leads to a complete response to the severe patient population that at least maintain for the whole year that they do not require any surgery and beyond. As a result of that, the FDA agreed that our Phase 1 single arm trial as well as our Phase 2 single arm trial can serve as a pivotal trial. And we did not have and they have we have not been required to do any kind of randomization or placebo controlled trial in that setting and that is very important. And one other aspects that I want to stress here is, and FDA agrees that these patient population, they are their own best control. And therefore, by having such a higher standard of not only in the number of being in a severe patient population, but also a robust endpoint that negated the need for having a randomization or placebo controls.

Speaker 2

So let's just take a look at what happened as a result of our Phase 1 and Phase 2. We had enrolled 12 patients in our Phase 1 and 23 patients in our Phase 2 single arms. And we recently in June actually presented the full set of data both from Phase 1 as well as Phase 2, the breakthrough session at ASCO. And what was there and it was received extremely well by investigators as well as our patients and patients in RRP for a number of reasons. First of all, if you look at the primary safety of this, it's extremely favorable.

Speaker 2

And it's also the efficacy when you look at the endpoints for this trial, which was a complete response, meaning that the patients go from number of surgery, which the average was 4.5 surgery per prior year before the treatment 2, completely zero surgery requirement 12 months follow-up and we have been by the way following these patients for a durability of response, which we have seen quite adorable responses in this patient population. 18 out of 35 of these patients went to a complete response. That's 51% of the population. If you look at our secondary endpoint, which was the reduction in the number of surgery, now we had 30 out of 35 patients, they reduced their number of surgeries. That's 86% of our population that was treated.

Speaker 2

This has been unprecedented result by any treatment for this patient population. There has never been a data that was presented with this robustness of an endpoint as well as the safety and also be it in the most severe patient population that clearly it really is the much tougher treatment to be treated, not only in this disease, in any disease in general as we all agree. So I think this was quite exciting. And as I mentioned, in 2023, in June 2023, we received the accelerated approval path and the rolling BLA. And our submission, we are on track to submit our BLA by the end of this year in 2024.

Speaker 2

We also what I'm very excited about is that we have initiated our enrollment in the confirmatory trial already And this we had reached an already agreement with the FDA that by the way our confirmatory trial are also single arm, no placebo requirement, no randomization, which as you can imagine, it's going to make things extremely challenging for these patients if you have to randomize because each patient is their own best control and the randomization is quite challenging and this is what all the investigators believe as well. We already not only have initiated the confirmatory trial, which is part of submission of the BLA, but we have started the enrollment. And I have to say that we are quite taken by the number of the patients that they already have shown excitement to participate in our confirmatory trial. On the side of our commercial scale for drug substance manufacturing, also our facility is operational and we are quite confident that we can adequately provide the doses for both U. S.

Speaker 2

And ex U. S. On a potential launch. And as part of our patient advocacy effort this year, we had the joint recurrent respiratory papillomatosis inaugural RRP Awareness Day on June 11 because this disease is actually as a result of the infection by HPV 6 and 11, therefore June 11. And we are really excited that we have been working very, very close So with that in mind, just to recap what we have done and we are why we are so excited and so focused on PRG in 2012 is we have established a well differentiated innovative therapy that doesn't require any device.

Speaker 2

You can give it subcutaneously. It elicits immune responses to the root cause of these benign tumors, which take place on the trachea or the vocal cord of these patients and cause a devastating scenario for these patients. And as a result of the mechanism of the action and the safety, advanced safety and safety that we have shown these patients, we get 51% of these patients going to a complete response, 86% of them reducing their number of surgery, the durability of response, the median has not been reached at this point is 20 months. Our Phase 1 patients that they have been obviously have a much longer follow-up have surpassed 32 months of the durable responses and have not required any surgery. So with that, we believe that this and we are extremely excited that this drug has the potential to be quite effective for RRP patients.

Speaker 2

And the first drug has the potential to receive the first drug ever approved by the FDA. So in that process, we also have been preparing for the potential commercialization of the drug in 2025. And in that setting, I am thrilled to welcome Phil Tennant as the Chief Commercial Officer for our company. And we have been very excited that Phil has joined the leadership and now currently leading all activities around the commercialization for PRG in 2012. And I would like to hand over actually to Phil to hear from him and his perspective on the commercial path of PRGN 2012.

Speaker 2

Phil? Great.

Speaker 3

Thank you, Helen. Thanks, everybody. Great to be here with you this afternoon. Please let me take a few moments to make some introductory comments about myself and then some remarks about the commercialization efforts of REGEN2012. So I'm now into my 4th decade in the industry and a common theme for my experience across the industry has been launch activity, experience of global launches, launches in the UK, Europe, Japan, Australia and now the U.

Speaker 3

S. And one of the common threads running through those launches has been the setting of new treatment paradigms and new standards of care, particularly in my most recent oncology experience. And many of those diseases have been rare diseases. They've been areas with high unmet need and few, if any, treatment options for patients. And so I'm aware of the impact that successful treatments can have on patients, on families and on the broader healthcare system.

Speaker 3

And so PRGN 2012 absolutely fits into that category, which is why I'm excited to be here and I'm excited for the potential for launch. Helen, I think, did a great job in summarizing the compelling clinical offering that this drug has, the reduction in the complete response rate of over 50%, the 86% of patients see a reduction in surgeries. And we've actually heard from patients that the reduction of a single surgery is extremely meaningful. So we appear to have a very effective treatment, well tolerated and it could reduce the burden on patients and the healthcare system quite considerably. The commercial team to date has been laying a lot of the groundwork for market access, for distribution.

Speaker 3

And now with me coming on board, we're beginning to really ramp up our full commercial launch preparation activities across marketing, sales, thought leader engagement, Congress activity publications and so on. So it is a very exciting time for the organization and a great moment for me to join. In terms of timelines, many of the commercial timelines are of course derived from the BLA submission timing and so that's a very important milestone for us. There is a lot to do in hopefully a relatively short space of time so that we can bring this treatment to patients in 2020 25. And in thinking about commercial build out, it is a rare disease, so the sales force footprint will need to be precise.

Speaker 3

But just as importantly, we need to think in parallel about our medical affairs organization, particularly the customer facing component of the medical affairs team so that we can deliver an integrated and seamless experience to our patients and our customers. And we look forward to making significant progress here during the remainder of this year and into 2025. So we continue to believe that this indication represents a significant market opportunity based upon the very high unmet need, the safety and efficacy results that we've seen and the prescriber preference in our market research. So with that, Helen, I hand back to you.

Speaker 2

Thank you very much, Phil. So what I would like to do in this part of the talk is really focus on our strategic prioritization. As a result of prioritizing 2012 for all the reasons that we mentioned and we are excited about for the potential commercial launch. Last week, we announced a series of strategic initiatives. Before I go and explain this, first of all, I would like to thank our Chief Operating Officer, Ritu Shah, who is here today with us for not only all the tireless work that he has done over the years for the buildup of this organization, but also especially the important role that he has played in really at this point for the strategic prioritization and some of the especially the operational aspects that we had to change and rapidly focus on our PRG in 2012.

Speaker 2

So I really thank Ritu for all of the hard work. Let's start by pointing out that as part of this strategic prioritization, we had to make the difficult and we had to redirect resources to our PRG in 2012. In the clinic, we have implemented also various cost saving measures as well. For instance, for PRGN-two thousand and nine, which is the treatment in a recurrent metastatic cervical cancer as well as in head and neck related HPV related cancers. We have focused the trials through our CRADA at MCI NIH and the PRG in 2009, it continues to advance through our CRADA partnership with National Sensor Institute.

Speaker 2

In regard to our UltraCAR T, as you are aware, we had 2, 3 clinical programs. And what we have done is we have announced the complete enrollment of PRGN-three thousand and 6, which is our ultracartine acute myeloid leukemia AML patients. Last year, we had reported on our Phase 1 data of the AML patients that they were treatment treated with our PRGENT 3,006. And if you recall, these are patients that they have failed number of treatments that unfortunately have very few months to live. And it was very exciting that we had reported 20 more than 27% objective responses in a very, very challenging patient population with our PRGN-three thousand and 6.

Speaker 2

Our patients had both complete responses as well as partial responses. And by the way, our PRGN-three thousand and six has received a fast track designation from the FDA. So I'm excited to announce that we have finished the Phase Ib of this, and we are preparing to move forward for discussions with the FDA in regard to their strategies for next steps. In regard to our PRGN-three thousand and five in ovarian cancer and 3,007, our ROAR-one card, the trials in order to minimize the spend, we have paused these trials currently. We are also looking at continuing to focus on a strategic partnership to further advance our UltraCAR T platform.

Speaker 2

In addition, we also have all passed all our preclinical programs across the company at this moment. Finally, we also have initiated a shutdown in ActoBio. It's our Belgium based subsidiary. Their portfolio and IP remain available for prospective transaction, of course, as we move on. As I mentioned, with that, what we have done is really try to focus our resources on the highest priority asset, which is our PRGN 2012 and prepare for a potential launch and now with having filled by our side that we are excited to prepare for a potential launch globally for this drug.

Speaker 2

So with that, I will now turn the call over to Harry for a financial update. Harry?

Speaker 4

Thank you, Helen, and good afternoon to all of those on the call today. As Helen mentioned earlier, it is a pivotal time for Precigen with our recently announced asset prioritization in what could be the 1st FDA approved treatment for RRP patients in the near future. Before I talk about the company's finances, I also want to publicly welcome Phil Tennant to the Precigen team. We're excited about the value that Phil has brought to the table in the short time that he's been with Precigen and I look forward to working with him as we prepare for the anticipated commercial launch of PRGN in 2012.

Speaker 3

I want

Speaker 4

to first touch on our recently announced prioritization of assets and the successful issuance equity issuance that we completed last week. Based on the prioritization of assets, which will result in streamlining of operations, the company expects to significantly reduce future operating costs. Last week's equity issuance netting $31,400,000 plus our cash and investments on hand, which totaled $19,500,000 at June 30, will provide a runway into early 2025. I've had many investors ask the question as to why we did not raise more than the $31,400,000 The short answer is that our it is our opinion that the company is fundamentally undervalued. In addition, the proceeds received last week allows us to focus on the advancement of PRGN 2012 in the near term, while providing us the time to consider various financing options inclusive of non dilutive options.

Speaker 4

Our focus has and always will be to utilize our resources to garner the highest value for our shareholders. With that being said, from a high level Q2 financial results perspective, our net loss for the quarter ended June 30 was $58,800,000 or $0.23 per share compared to a net loss of $20,300,000 or $0.08 a share in the period ended June 30, 2023. It should be pointed out that the 2024 period net loss includes $32,800,000 of non cash impairment charges net of tax benefit specific to our ActoBio business. We filed our 10 Q as well as our quarterly press release on financial results and business update with the SEC just prior to this call. You can find more detailed financial information in those documents.

Speaker 4

With that said, I'd like to open the call up for Q and A. Operator?

Operator

Thank you. Ladies and gentlemen, we will now begin the question and answer Your first question is from Ben Burnett from Stifel. Please ask your question.

Speaker 5

Hello, good afternoon. This is Carolina Ivanente Santoso on for Ben Burnett. To start with, recently a close competitor has announced it has delayed its BLA filing. What are the gating factors for you to commence the rolling BLA submission of PRGN 2012 and this way ensure you keep a meeting in RRP?

Speaker 2

Hi, Tal, and thank you for the question. So in regard to obviously, we are laser focused on our submissions. And as we have guided before and continue to guide, we anticipate to submit our BLA by the end of 2024 and we are on track for that. I think we're as I mentioned, we are really excited about our PRG in 2012 and the differentiation of this gene therapy treatment for the ease of the treatment, which is a subcu injection and does not require any kind of devices and the complexity there as well as obviously the safety favorable safety and supported by really outstanding efficacy that we see as far as complete responses followed by also secondary endpoints of reduction in the number of surgeries. So with that, I would just guide that we continue to focus our efforts on our drug treatment and really positioning it for potential launch in 2025.

Speaker 5

Okay, understood. And then as a follow-up, given that PRG M20 12 represents a novel therapeutic modality for RRP, do you think you will get an ATCOM meeting? And what can you do to prepare for it if

Speaker 2

there is 1? Thank you. So thank you. I think these are questions that obviously we cannot answer if there are outcome meetings. And in general, the way I look at these things, it's that is always FDA has that call to have outcome meetings.

Speaker 2

But in general, when you look at the diseases, the outcomes come at the times that there are perhaps there are questions in the consistency of the data or in the various, let's say, groups. And in this case, what I like to express is that if you look at our 2 pivotal data, it's the consistency is actually really amazing. In a Phase 1, which we recruited, which were 12 patients enrolled, we had 50% complete responders. And basically, in Phase II, we had 52% complete responders. So you cannot come any closer in a clinical trial at this kind of data.

Speaker 2

And same thing, by the way, for our secondary endpoints and immunological responses. So the way I usually answer this question, adcoms are always at the discretion of the FDA and it's not according to the company. But also, we believe that our clinical data has met both primary and secondary endpoints completely. And I think the data spoke for itself at ASCO.

Speaker 5

Got it. Much appreciated.

Operator

Thank you. Your next question is from Jason Butler from Citizens JMP. Please ask your question.

Speaker 1

Hi, thanks for taking the questions. Just had one for Phil Cannon as he joins the company. I'm wondering if you could just give us his high level thoughts on what attracted him to the opportunity, how he thinks about the opportunity in RRP and what the priorities will be in the coming months as the BLA is submitted and reviewed by FDA? And then I have a follow-up. Thanks.

Speaker 2

Hi, Jason. Phil?

Speaker 3

Sure. Yes, I think thanks for the question. I think I alluded to that in some of my comments earlier. Given my history, particularly in oncology, some of the rare diseases that I've worked in, the rare tumors, the high unmet need, the lack of available treatment options for patients, I am aware of where therapies can have such a significant impact on patient populations, on caregivers, on the healthcare system. And so this is one of those areas that I think fits into that category perfectly.

Speaker 3

A very high unmet need, nothing other than surgery and multiple surgeries at that for most patients. And it's crying out for therapeutic alternatives. And so that's fundamentally the attractive nature of this disease for me. It's consistent with what sort of kept me going in my career to date and it's an opportunity that I relish as we go forward. The priorities moving forward as you would expect, time is ticking.

Speaker 3

So as I come on board, it's really about rightsizing the opportunity and then commensurate with that making sure our commercial footprint and our build is appropriate that we understand who the treating healthcare professional is. We understand the multidisciplinary approach to that to the patient. We understand the patient journey and we build our commercial and our medical affairs teams accordingly so that we can best support the patient, best support the customer and make this as seamless as possible to get this new treatment to those patients who obviously are in need of it.

Speaker 1

Great. Helpful. Thank you. And then, Helen, can you just talk about in terms of the strategic prioritization, how we should think about the UltraCAR T programs? I guess 2 part question here.

Speaker 1

One for PRGN-three thousand and six, will we get a clinical update or an update on the clinical data this year? And how are you thinking about or what is the interest level or prioritization already been on looking for

Speaker 2

question. So in regard to our ultra car, first of all, I have to mention, we are extremely still very excited about this platform. As I have mentioned and I will continue to say that this is currently the only platform that it can deliver autologous CAR T overnight in a setting of the hospital to the patient with substantially less cause. And not only doing that, the manufacturing is really it's the paradigm shifting and we have been treated now more than 70 patients that it speaks to the ability to do this at the hospitals and treat the patients and not only from a perspective of the safety, which has shown a very favorable safety, but also directly manufacturing these autocar Ts in the patients and also seeing objective responses. So, we the reason for what we have done as far as pausing some of the two trials they were going obviously has been really focusing on TRGN 2012 and are basically commercial preparedness for potential launch for 2012 in next year.

Speaker 2

And that doesn't mean that we the value of our UltraCAR T platform is any less than before our excitement about that. However, we had to take the tough decision and give the priority to what requires the priority at this moment. However, what we have done, and I'm very proud of our clinical team, is that we have finished actually our Phase Ib in our most advanced PRGN-three thousand and six, basic in AML indication. And we will be in as we move forward and we will communicate about the data and the guidance on showing the data. However, what we are currently doing, as you know, we had received the fast track designation, which is very important, And then discuss the regulatory and then discuss the regulatory strategy for advancement of this in the upcoming months to next 2025.

Speaker 2

So we are excited about that and we will continue with those activity. But at the meantime, since we have finished the enrollment of the patients for the Phase 1b, obviously, we are not occurring the clinical costs that is related to this asset. And that, again, further helps to put our resources on 2012.

Speaker 4

Great. Thanks for taking the questions.

Speaker 2

Sure. Thank you, Jason.

Operator

Thank you. Your next question is from Swayamp Ramonson from H. C. Wainwright.

Speaker 6

Thank you. This is RK. Good afternoon, Helen, Ritel, Kjell and team.

Speaker 1

So

Speaker 6

2012 program, would we see any additional data at all until you start talking about the confirmatory study? And I have a couple of more questions after that.

Speaker 2

Sure. Hi, Yaki. Thank you for the question. So we have shown the both Phase 1 and Phase 2 data, especially at ASCO, all the data was presented, including the safety as well as the efficacy, tolerability and durability and the immunological responses. So and as I mentioned, we have met the requirement and actually exceeded the requirement for the meeting the endpoints of the both Phase I and Phase II.

Speaker 2

We are currently, obviously, as I have mentioned, we are preparing for BLA submissions and rolling BLA by the end of this year. So there would be no further data because the data is what FDA had asked us from Phase I and Phase II and that has been completed. Of course, one of the things that is ongoing with our patients is the durability of response and those patients that they have participated in a Phase 1 and Phase 2, they continue to be followed by their physicians as they move on and that data will be followed and of course reported accordingly at times.

Speaker 6

Okay. And then in terms of applications to regulatory authorities, is there any are you folks discussing a potential submission in Europe for the same indication?

Speaker 2

Yes. Excellent question. So as I mentioned, we had already engaged with EU authorities and ex U. S. As we not only received the Orphan Drug Designation, but we have obviously initiated our efforts globally.

Speaker 2

I don't go to the all the details for a strategic reason, But we are very excited about the potential of PRGN-twenty 12 in ex U. S. And Europe. And as I mentioned, our facility, commercial facility as they have started their manufacturing, We have every confidence that by 2025, we will be in the position to provide the drug globally, both from for U. S.

Speaker 2

As well as ex U. S. So we are excited about that, and we look forward to that. And I leave it at that.

Speaker 6

Okay. And then one last question, this is for Phil. Since this is a rare indication, what sort of what size of a commercial team do you need to set up before you get into the market?

Speaker 3

Yes, that's a great question. As I mentioned earlier, because it is a rare disease, we have to be precise in our thinking. The footprint doesn't need to be we're not talking 100 of sales team, for instance, we're talking tens. But the important thing that I would stress is that we've combined that with our thinking on medical affairs. So we have a joined up approach from an internal perspective to our external environment.

Speaker 3

So it's going to be a small but perfectly formed team hopefully, particularly in terms of the customer facing aspect.

Speaker 6

Perfect. Thank you. Thanks for taking all my questions.

Speaker 2

Thank you.

Operator

Thank you. Your next question is from Brian Cheung from JPMorgan. Please ask your question.

Speaker 7

Hi, thanks for taking our question this afternoon. This is Sean on for Brian. Could you remind us what the bar for response you have to see in your confirmatory trial is? And based on your conversations with the agency, do you need to complete enrollment in this confirmatory trial before you receive the approval?

Speaker 2

Yes. Very good question. Thank you, Sean. So the bars for confirmatory trial is similar to what we had for Phase I and Phase II. The design is also exactly the same.

Speaker 2

As we have mentioned, we do not have to it's a single arm and no randomization, no placebo control required, which as you can imagine, that can be quite challenging enrollment to the placebo or randomizing these trials, Phase III trials. And as far as as part of the accelerated path, of course, there's a confirmatory trial, but it only needs to be initiated at the time of a BLA submission. And also, it's not a requirement for approval that you have finished the confirmatory trial. However, as I mentioned, we are really excited not only we have already initiated our confirmatory trial, we have enrolled to our confirmatory trial. And based on the reaction of the the that was presented at ASCO by patients to enroll into these confirmatory trials, which obviously being single arm, no randomization and exact same designs as we had before.

Speaker 2

And with the patient population that is extremely interested in basically enrolling, we are really excited that what we can do with this innovative treatment for our patients.

Speaker 7

Thanks for the additional color.

Operator

Thank you. Your next question is from Jennifer Kim from Cantor Fitzgerald. Please ask your question.

Speaker 8

Hi, thanks for taking my question. Maybe a follow-up to the last question on the confirmatory trial. Can you talk about what you would expect the pace of enrollment in that trial to look like maybe in comparison to the prior trial?

Speaker 3

Yes.

Speaker 2

Hi, Jennifer. It's an excellent question. Actually, if you recall, the way our Phase 1 was we maybe I give if you allow me to give a little bit of the history of this. We have started our Phase 1 arm in, I would I think April or May of 2021 in the midst of COVID. And we have finished the enrollment of our patients by December of 2021 to our Phase 1.

Speaker 2

So you can imagine, we had 3 patients in dose level 1 and 12 patients in dose level 2 and 15 patients we had already finished in the span of a little bit more than 6 months. We had started our Phase 2 single arm in January of 2022 and we finished in May of 2023 and that was 23 patients that we, again, recruited in really a very short amount of time. And by the way, all of the 35 patients and during the COVID And at that point, we had not really in the middle of our Phase 2, we had started showing our Phase 1 data. So you can imagine now after ASCO and basically the reception that PLGN 2012 got through the breakthrough session with hundreds of investigators being there was very clear and the data and the consistency and safety of the data has added obviously to interest of all the patients with this devastating disease that they really have no treatment for. So we have currently many, many, many patients.

Speaker 2

We are not going to guide on the exact timing of this, but obviously you can imagine that we already have initiated, we have started enrollments and we have a large patient population that they are asking to receive this drug. So we are confident that we can finish our confirmatory trials in a very orderly and fast fashion, and we are looking forward to bring the value to our patients.

Speaker 8

Thanks, Ellen. And maybe one question for Phil. Phil, since your background seems to focus a lot on global development as well, I'm wondering is that something you're exploring? And what are sort of the steps to understand what's required to look at ex U. S.

Speaker 8

Markets? Or when you're thinking about monetization or other strategies, is that something that you're considering? Thanks.

Speaker 3

Yes. Thank you for that question. Absolutely, we have global ambition with PRGN 2012. So we would approach market sizing opportunity assessment in much the same way that we would do for the U. S, for instance.

Speaker 3

And there is a sizable disease burden. Obviously, the unmet need is still high. Different countries have different vaccine programs, but the impact of those vaccine programs for the younger population to flow through into the adult population is probably 20 to 30 years out.

So yes, we are absolutely looking at all of those opportunities ex U.

I want to take this opportunity to truly thank our TMAT presages for their tireless work over the past several years.

And I just want to highlight my gratitude and also say I'm stand privileged to stand next to this team at such a high caliber. So thank every one of the members of this. Of course, we thank our patients for the trust and the enrollment, and we are happy with the results that we are seeing for our patients.
