Operator

Good afternoon, and welcome to the Precigen Full Year 2023 Financial Results and Update Call. At this time, all lines are in listen only mode. Following the presentation, we will conduct a question and answer session. Please note that this event is being recorded. I would now like to turn the conference over to Steve Harrison, Vice President of Investor Relations.

Operator

Please go ahead. Excuse me, Mr. Steve Harrison. Please go ahead.

Speaker 1

Thank you, and I apologize for any technical difficulty here. Again, welcome to our 2023 full year financial call. With me is our CEO, Helen Salisbury CFO, Harry Tomacian and Jim Schafer. Please refer to our most recent filings for our forward looking statements. With that, I'll turn the call over to Helen.

Speaker 1

Thank you.

Speaker 2

Thank you, Steve, and thank you to everyone for joining us. And again, apologies for this little bit of technical problems. But I think we are going through a very, very transformative year. 2024 is poised to be a transformational year for prostagens. We are on track to present a pivotal Phase 2 data for our lead asset PRGN-twenty 12 in Q2 and intend on submitting our BLA in the second half of twenty twenty four.

Speaker 2

This is due in part to the positive guidance and pathway provided by the FDA and to the tireless work done by our team over the last several years, starting from discovery in 2020 all the way to the potential filings in 2024. For today's call, I will focus on our Adanwirth platform, and we are working rapidly and prudently to advance our obviously our ultra car assets and we are looking forward to the Zaida readouts later on this year for Ultra Car platform as we outlined in today's press release. So for today, let me just jump into our Adanwirth platform, why we are excited about this platform and our lead assets that is based on. For those of you who might not be familiar with this platform, this is a very differentiated platform from the rest of the viral platform. Why do I say that?

Speaker 2

It's very simple. First of all, this platform is built based on the library of the guerilla adenovactors. These adenovactors are not like other adenovactors. First of all, they have a high capacity that you can put number of genes in them. But more importantly, they have the ability because there is no pre immunity in humans or very little, you can keep dosing this with this vector.

Speaker 2

With all of the other viral vectors, when you dose once or at best twice, you're getting this neutralizing antibody with eventually inhibited immune responses. And then after a while you're just shooting a blank. That's one of the major issues in the vectors, other vectors and other platforms that exist. Here, on the other hand, because we don't have pre immunity to this, you can keep on giving. And because of the design of these factors and the specific biological nature of these factors.

Speaker 2

Now even when there is a neutralizing antibody kept at bay and doesn't enhance it. Why do I say that? We have clinical data actually from various indications that you can be dosing the patient and we have dosed some of the patients up to 18 times. And not only you have kept enhancing their immune responses, but you have kept the neutralizing antibodies at bay. And finally, one other aspect of the platform, which is very important, is the specialized manufacturing process, which allows high titers.

Speaker 2

And you can imagine that becomes very important, especially in commercial manufacturing process. So let's dive into our lead asset, which is our PRGM 2012. Our PRGM 2012 has been designed to identify the epitopes HPV 6 and 11 and target the cells that are infected with this virus. Why is that important? In a rare disease of basically RRP or recurrent respiratory papillomatosis, the root cause of this disease is the infection, HBV-six eleven infection in these patients, which then causes these benign tumors on the vocal cord or in the trachea of these patients.

Speaker 2

Therefore, they can talk or they can breathe or book. These patients for decades have gone through this devastating disease with really no treatment except surgery. What does surgery do? Keep removing this benign tumor, it's like mowing your grass and then they keep coming back. And as a result, the patient, first of all, it gets worse the situation, there is a danger and there is a continuous problem that you have not solved.

Speaker 2

In the order to really address this disease, you have to get to the root, which means what? Means that you have to address the infection underlying HPV 6 and 11. And this is exactly what we designed PRG in 2012 to do to abatement the immune responses of these patients to identify these cells that are infected and cause their benign tumors to grow and then to destroy them. And based on that, what we have done is look at the number of the patients. In United States, there are estimated between to 20,000 patients.

Speaker 2

Ex U. S, you are looking at excess of 125,000 patients. So as we mentioned, this is truly a devastating disease with no current treatment. When we started our trials with PRGM-twenty 12, we first of all designed the trial that the patients, they have the history of the patient in 12 months prior to receiving their vaccine. And then these patients, they receive a course of 4 vaccination within 85 days.

Speaker 2

And then after that, we have been following these patients to see for the recurrence of this benign tumor. In a single arm Phase 1 pivotal trial that we run originally, what we observed was, first of all, from a safety perspective, these patients have very favorable safety, mainly grade 1, grade 2, which is some rashes at the site of injection or some fever and then it resolved within a day or 2, very similar to the flu shots that you get. Secondly, one thing that was very specific about our design for this vaccine is that it's given subcutaneous in the arm or leg, again, similar to the flu shot. We don't require any kind of a device. We don't require anything.

Speaker 2

It can be done in any office of any of the physicians, right? So now what we saw besides the safety and the endpoints that we had put, we decided to go to the most severe patient population. What do we mean by that? We define that and our KOLs investigators have defined that as patients that at least require 3 surgery in a prior year. Actually, the average number of surgeries that our patients have in our trial was upwards of 6 surgery per year.

Speaker 2

So you can imagine, every couple of months, this patient had a surgery, some of them they had 10 surgeries in the prior year. What we observed was after the follow-up of 12 months, 50% of these patients did not require any surgery and we refer to them as a complete responder. If we look at overall Okay. Now when we look at the immunological responses of these patients, the patients that they had the complete response, they have a significant increase in their immune responses to HBV-six and eleven. And this is exactly what the mechanism of this vaccine is all about.

Speaker 2

At the same token, one thing that we have to say, we have been following now these patients for more than 12 months. Actually, these patients are in full response and they are upwards of 24 months. This is 2 years after vaccination. And again, I'm going to stress, severe patient population with the average number of surgeries fixed mean average, right? So when we look at also, we had based on the data, the safety, the efficacy, the FDA last year for the first time in the history of any company has given us a breakthrough designation as well as accelerated path and agreed that our single arm pivotal Phase 1 data plus a single arm Phase 2, which we had started, can act as pivotal and based on that we can submit a BLA.

Speaker 2

So as we have mentioned, last year we finished the enrollment to our Phase 2 and we are really excited that we will be presenting the full data set of our Phase II by the end of Q2. We already have published in the science translation our complete Phase 1 data and the mechanism of action of that. And we are post to submit our BLA in the second half of this year. And we have received an agreement from the FDA that we have enrolling BLA. So as you can imagine, this is quite exciting and also a proof of concept for this platform.

Speaker 2

Simultaneously, we have been advancing another molecule PRGN-two thousand and nine and that has been already positioned in HPV 1618 cancers, head and neck cancer, cervical cancers and the Phase 2 studies in head and neck has been initiated last year and we are currently enrolling and recruiting patients to this arm of head and neck with the early onset of the disease. And this is quite exciting. Why? Because when you look at the head and neck, the response rate of the patient even to the checkpoint inhibitor has been 18%. So there is a wide gap here for the improvement.

Speaker 2

Last year at ASCO, we showed that when we treated HPV related cancer patients, these are a Stage 4 patients. These patients had basically we had 30% objective responses, partial responses, complete responses and the complete responses, they were durable. We had over a year, for instance, that response in some of these patients. This is in a patient population that I stress again, checkpoint inhibitor in cervical cancers at 15% and then they fell for in head and neck 18%. So now positioning PRGN-two thousand and nine in a head and neck in combination with the pembro in an early onset is quite exciting and this trial is recruiting and we have enrolled patients to this arm.

Speaker 2

Simultaneously, we moved these assets towards the cervical cancer. Last year, we received an IND approval from FDA to open the Phase 2 study in combination with pembro in a relapsed metastatic cervical cancer patient. And currently, as we speak, we are recruiting to this trial and this is quite exciting. So as you can imagine, this platform with the differentiation that it has from all the other platforms, with the efficacy that has shown and in our lead PRGN 2012 based on its safety, clinical efficacy and also in discussions with the KOL and investigators. There's high excitement about this molecule for this rare disease because of ease of administration, because of efficacy of clinical response and the durability of response has generated a lot of excitement and really has positioned us to become a leader in treatment for these rare disease.

Speaker 2

So with that as a highlight, I would like to now actually transfer to Harry Tomacian to give us our CFO an update on our financials. Harry?

Speaker 3

Thank you, Helen, and good afternoon to those on this call. We appreciate you participating. As Helen mentioned earlier, 2024 is shaping up to be a transformative year for Precigen. We are all well on our way to completion of our drug substance manufacturing facility here in Germantown, Maryland. And with the hiring of our Head of Commercial Operations in September of this past year, we are continuing to build out our commercial function and plan to be ready for the expected launch of PRGN-twenty 12 in 2025.

Speaker 3

In addition, we anticipate that there will be multiple value inflection points in 2024, starting with our data readout on PRGN 2012 in the Q2 of this year. As we approach the end of the Q1 of fiscal 2024, we're continuing to exercise sound financial management preparing for the planned launch of PRGN-twenty 12 and 20 25 and continuing to move our other programs rapidly through the clinic, all while maintaining efficient SG and A operations. With that in mind, I'd like to spend a few minutes highlighting certain aspects of our financial results from 2023. In 2023, our research and development expenses were $48,600,000 an increase of 3% to $1,400,000 from the prior year. This was primarily due to additional investment in our personnel, mostly through adding additional headcount to support the growth in the company's development activities.

Speaker 3

Our continued focus on SG and A costs resulted in a decrease of 16% or $7,600,000 from the prior year to $40,400,000 for the full year of 2023. This was due primarily to reduce legal and insurance costs and was achieved while we began to build out our commercial group. We filed our 10 ks with the SEC just prior to this call, and you can find more detailed financial information in the financial statements, which are included in the 10 ks. In addition, we are continuing to evaluate various opportunities and are current and are confident in our ability to strengthen our balance sheet as we approach the planned launch of PRGN 2012 and transitioning from a clinical to a commercial stage company. This concludes our prepared remarks for today.

Speaker 3

I'll now turn it over to the operator for any questions.

Operator

Thank you. Thank you. Ladies and gentlemen, we will now conduct the question and answer session. Your first question comes from Jennifer Kim from Cantor Fitzgerald. Your line is now open.

Operator

Jennifer? Your line dropped. Your next question comes from Jason Butler from Citizens JMP. Your line is now open.

Speaker 4

Hi, thanks for taking the questions and congrats on all the progress. So the 2 for me. First of all, in terms of the PRGN 2012 Phase 2 trial, can you maybe just compare the trial design here, patient population, anything about trial conduct to the Phase 1 study that we already have the data from and know any differences? And secondly, Helen, at this point, any more color you can give us on the design of a confirmatory study that you would conduct for 2012 assuming you've got accelerated approval? Thank you.

Speaker 2

Hi, Jason. Thank you. Excellent question. So in regard to the Phase I and Phase II study, actually the design is exactly the same. And this is why FDA has allowed us to combine the Phase 1 single arm and Phase 2 single arm and consider that as a pivotal.

Speaker 2

So we are really excited about that. There was no different design between these two and this will total 35 patients that the data will be reported on. In regard to the confirmatory trial, also we have full agreement with the FDA already that the confirmatory trial would exactly duplicate what we have done in a single arm Phase 1 and Phase 2. So it's the exact same design. However, one interesting point here, and I think it's very, very important that based on the safety and the efficacy that we showed, and the FDA has seen that data, FDA has recommended that we also consider an arm.

Speaker 2

This is not a requirement for a confirmatory. This can be separated or done differently. However or we can even add it to the confirmatory trial if we wish to. But for every piece of those things because the consideration that those ADs, the other 50% of the patient that they didn't go to a complete response, however, they benefited and they reduced their number of surgery, they might be able to go towards a complete response. And we are really excited about that.

Speaker 2

We already have the design of confirmatory based on what we had designed before. And clearly, upon our BLA submission, our confirmatory trial will start as going to be initiated simultaneously.

Speaker 4

Great. Very, very helpful. Thank you, Helen.

Speaker 2

Thank you,

Operator

John. Your next question comes from Jennifer Kim from Cantor Fitzgerald. Your line is now open.

Speaker 5

Hey, can you hear me? Yes. Hi, Jennifer. Perfect. Sorry about before.

Speaker 5

Maybe to start off, have you decided on your plan in terms of the format or venue for presenting the Phase 2 data? And then my second question is just from a commercial readiness standpoint. Can you give more color on the manufacturing side and how much capacity do you anticipate having at timing of a potential launch? Thanks.

Speaker 2

Absolutely. Thank you, Jennifer. So from the obviously, we are looking at various options that we have and we will give a little bit more guidance as we get closer. But clearly, we are looking forward to presenting the full set of data on our Phase 2 and our investigators also similarly. So we will be guiding soon.

Speaker 2

In regard to the commercial readiness, our commercial facility is actually is exactly moving according to their plan. And we will have a capacity that at the time of launch to meet not only the number of the patients and actually we have by then have generated in thousands of doses that the patients can be treated with. So we are confident that we can meet the needs of the commercial basically force and our patients as we move forward.

Speaker 5

Okay. That's helpful. And maybe to follow-up on what you said before on the arm to look at repeat dosing. Is there any data or feedback that you're waiting on before you sort of pull the trigger on making that decision?

Speaker 2

No, actually that is the arm that the design is has been up to us because that is not a requirement for a confirmatory from FDA. Our confirmatory trial is already agreed by FDA and it actually is in the process as I mentioned. Upon our submission of the BLA, we also have initiated that going forward. The repeat dosing is what we have designed in conjunction with our investigators. And that we will also add as part of our confirmatory as another arm.

Speaker 2

But then again, that is not a requirement by the FDA. This is additional to expand our label and as well expand the patient population that they can benefit from repeat dosing, especially with the durability that we see currently, which is more than 2 years.

Operator

Your next question comes from Koyampakkalpamakkam from H. C. Wainwright. Your line is now open.

Speaker 6

Thank you. This is RK from H. C. Wainwright. Good afternoon, Alan and Hari.

Speaker 6

So I have one question on 2012. In terms of commercializing the drug, can you give us some of the aspects of it in terms of like sales folks and what sort of what is the strategy there? And it being an orphan disease, do you focus on some specific centers where this is being treated? Just some of the dynamics of that, please. Yes.

Speaker 2

I'm going to ask Jim Schaeffer, Head of our Commercial to actually give colors to that. Jim?

Speaker 7

Thank you, Helen. We have recently completed primary and secondary market research to better understand not only the patients, but also the physicians and the prescribers who currently manage the RRP patients across the U. S. And what we continue to identify is that it's a relatively small group of specialty physicians, primarily laryngologists, which are sub specialty of AT physicians that are managing the large majority of patients. So we will be able to create, hire and train a specialty sales team focused in the major metropolitan areas and very efficiently be able to increase awareness, launch and then promote our product once approved.

Speaker 6

Okay. Thank you for that. And then going off onto the UltraCAR T cell therapies, the 3,007,

Speaker 4

where

Speaker 6

you're doing the dose escalation study now and hoping to present some preliminary data. What sort of data would we see in terms of like the dose ranges? And also, how soon can you get into Phase II based on what you get to see from this portion of the study?

Speaker 2

Yes. No, thanks, Saket. So in this trial, actually based on our prior trial, we are there is a 2 dual cohort here. However, this is an umbrella trial as we have mentioned before. That basically means we are addressing number of indications, both hematological as well as solid tumors, especially the triple negative breast cancer.

Speaker 2

This is going to be very exciting. And what we are looking and the guidance that we have given, we will be giving some updates on the interim data by the end of 2024. And we will be moving upon the dose selection as well, obviously finishing all of the safety. Then the trial moves to the expansion phase, Phase Ib. And again, those are the discussions that based on the data that we will see, we will have with the regulatory bodies, the similar type of things as we currently have with, for instance, our AML, which is in a patient population that they really have no other option in front of them.

Speaker 2

And as you are aware, other CAR T and TCRs have not been able or even the off the shelf have not been able to insert into that arena. And also, the small molecule inhibitors, unfortunately, is addressed only at certain percentage, 6% to 7% of the patients that they have those mutations, for instance, in FLETC3. And as we have seen based on the data, those patients, unfortunately, after a year also, there is a mutation in their tumors and they relapse and they have to look for other options. So I think we are really excited about that, our CAR T and the results that has been showing. And then we will be as we have given the guidance, by the end of 2024, we will present the data on expansion.

Speaker 6

Perfect. Thank you. Thank you very much, Helen and team for taking my questions.

Speaker 2

Thank you.

Operator

Your next question comes from Brian Chiang from JPMorgan. Your line is now open.

Speaker 8

Hey guys, thanks for taking our questions today. First one is on your first one is on the RRP prep. So based on your market research, how should we think about the initial adoption trajectory within RRP if you were approved today? Is there a lot of pent up demand? Or do you think that this will be a small build over time type of launch?

Speaker 8

And I have a quick follow-up. Thank you.

Speaker 2

Okay. I think, Brian, I'm going to let Jim Sheffer answer that and I can add to that as well.

Speaker 7

Yes, Brian, thanks for the question. As I mentioned earlier, we recently completed a commercial market assessment for the U. S. And the rest of the world markets for RRP and for PRGN 2012. We feel like the overall uptake is going to be relatively swift because a large majority of the patients are sitting and managed by a relatively small number of laryngologists across the U.

Speaker 7

S. So as we educate and increase awareness about the product availability, we think that's going to be relatively quick with those physicians and patients. So whether it's a 3 or 4 year uptake curve to peak and then with some level of retreatment that occurs for the rest of the overall sales build over time. Does that answer your question?

Speaker 8

Yes, it does. So on the maybe just on expenses, how should we project sales related expenses as you prepare for the launch? Any color on the projected cash runway? And what is the latest update on the partnership for UltraCAR T?

Speaker 2

Okay. So I can take the some of this and then definitely Harry can add to it. In regard to our as Harry mentioned, we are looking at the various strategies for basically supplementing our financial balance sheet, and we are confident that we as we move forward, we have that ability. In regard to the UltraCAR T, actually, I'm glad you asked that question because as you can imagine, especially with the evolution and the scenarios that have happened, we saw all in the past 6 months, the change of the label even in approved CAR T for the reason that the classical CAR T, unfortunately, some of the patients have come down with cancers of associated with the CAR T. And now that has to be projected in the label at the same token.

Speaker 2

Now this puts another cloud on the field of autoimmunity using this classical CAR T because in a cancer patient, of course, you're dealing with indication that the patients have no option and they have no other treatment. On the other hand, when you are looking at the chronic diseases such as lupus or anti anti immunity, clearly, now you have to have a very, very safe drug, because number 1, these are not patients that are at Stage 4. These are patients that they can live for long periods of time. And secondly, most probably, they have to be redosed over their chronic disease. So you in that setting, you have to have 2 phenomena.

Speaker 2

Number 1, the safety to ensure that someone that would have had otherwise a long life, you cannot be exposing to the scenario that they might develop cancer as a result of the treatment that they receive. Number 2, it's because It becomes very, very important, especially in chronic diseases because as we can see currently even the cost in a cancer indication is not bearable on our system. Left alone, now you go to the chronic diseases. For those reasons, the platform that we have developed and it's moving forward. And by the way, across the indication, we have now treated more than 70 patients in this platform.

Speaker 2

And number 1, the ease of the manufacturing overnight at the hospital, which then does not require the costs that are associated, as you can imagine, with centralized manufacturing. And number 2, the design of these CAR Ts that we have currently, which do carry safety switches within them. It's under if anything goes wrong, you can eliminate this stuff. Thankfully, we have not to activate these stuff. But obviously, we have done all of the preclinical studies.

Speaker 2

And of course, these were part of our IND packages that was given to FDA. And I think this is the advantage that currently our CAR T and the combination of those two factors obviously have created a lot of excitement and also attention. So we will be updating as we move forward in regard to our basically partnership activity, but this is going to be a very exciting year.

Speaker 3

And Brian, I'll touch on your question around cash runway. I'll start with the historical cash burn. So last year 2023, our cash burn was about $68,500,000 or an average of about $5,700,000 per month. There'll be some increased expenditures with the build out of commercialization and manufacturing capabilities, but through financial management, we're trying to reduce spend in other areas of the company. I will go back to my prepared remarks and reiterate that we're continuing to evaluate various opportunities and we are confident in our ability to strengthen our balance sheet as we approach the planned launch PRG in 2012.

Speaker 8

Thanks for the color. Thank you.

Speaker 1

I see no further questions, Lester. Let's turn it back to Helen for concluding remarks.

Speaker 2

Thank you, operator, and thank you to all of those that joined us for our update call today. As you can see, 2024 is poised to be a transformative year for us at Precigen, especially as we transition from a clinical to a commercial company. With pivotal Phase 2 data underway and the plans to submit a BLA in the second half of this year, we are poised to deliver health to patient population with no alternative and drive shareholder value. We look forward to communicating further in the coming weeks months. Thank you again for joining us today.

Operator

Ladies and gentlemen, this concludes today's conference call. Thank you for joining. You may now disconnect.
