I will now hand the call over to Dr. Frank Bedu-Addo. Frank? Thank you, Nicole, and welcome to everyone to our third quarter 2023 conference call. We are excited about the strides we're making, fueled by our commitment to developing groundbreaking therapies that revolutionize cancer treatment based on our proprietary Versamune platform and IL-12 fused antibody drug conjugate, PDS01ADC, formerly known as PDS0301 or M9241. The clinical data stemming from the PDS01ADC asset, which we acquired nearly a year ago from Merck KGaA, Darmstadt, Germany, continues to advance and mature, reinforcing our belief that this innovative ADC could potentially address the safety and efficacy limitations that have been observed with cytokine therapy to date. The combination of Versamune-based approaches and our IL-12 ADC has demonstrated the potential to overcome the limitations of effectively treating advanced cancer and extending patients' lives with immunotherapy. Currently, we have safety data for over 250 patients who have been treated with PDS01ADC, supporting the early data suggesting that this innovative ADC effectively directs the IL-12 into the tumor, therefore reducing its presence in the circulating blood and subsequently limiting the adverse events that have been reported with other cytokines. In addition, the increased and sustained presence of IL-12 in the tumor has been shown in our ongoing trials to enhance the clinical activity. This novel modification of IL-12, therefore, presents us with a unique opportunity to address a broad range of cancers. We continue to move this ADC forward with various promising approaches. It is being developed as a monotherapy. It's also being developed in combination with Versamune-based approaches and also in combination with other standards of care. I will talk more about these updates on PDS01ADC later on the call. We are pleased with our current progress, driven by our mission to develop groundbreaking therapies that transform cancer treatment. Our immediate objective revolves around progressing our primary clinical candidate, PDS0101, to the market. PDS0101 represents a novel investigational HPV-16 targeted immunotherapy that triggers a potent and precise T-cell response against HPV-16 positive cancers. This quarter, we made significant progress on our Versamune platform, specifically with our phase II VERSATILE-002 trial. We hosted a positive Key Opinion Leader, or KOL event, that included key opinion leaders who have been part of the VERSATILE-002 trial and others who have not been part of the trial and are leaders in the head and neck cancer field. It was important to understand how head and neck cancer expert oncologists view the trial results, and the potential for PDS0101 and KEYTRUDA to become the standard of care for recurrent or metastatic head and neck cancer. Overall, the experts were enthusiastic about the updated VERSATILE-002 data and the planned initiation of the phase III VERSATILE-003 trial. At this event, we presented data from both the immune checkpoint inhibitor-naive, or ICI-naive, and the ICI-resistant patient cohorts, both of which demonstrated impressive patient overall survival. For today's discussion on the VERSATILE-002 trial, we will focus on the ICI-naive group. With this population, we reported a 24-month overall survival rate of 74%, which means that on the combination of PDS0101 and KEYTRUDA, the probability that a patient will live at least two years is 74%. To put this number into perspective, published 24-month overall survival rates for approved ICIs is less than 30%, meaning that on today's approved therapies, the probability that a patient will live for at least 2 years is only about 30%. The VERSATILE-002 data suggests that patients are living longer when treated with the PDS0101 plus KEYTRUDA combination. It is important to note that disease control, which includes stable disease and tumor shrinkage, was seen in 81% of patients. Tumor shrinkage was reported in 60% of patients, and a confirmed objective response rate, or ORR, of 27% was reported based on investigator assessment. With respect to safety, the combination continues to be well tolerated, with 13% of patients having Grade 3 treatment-related toxicities and no patients having any Grade 4 or Grade 5 treatment-related events. To put this in context, in KEYNOTE-048, it is reported that 17% of patients on KEYTRUDA monotherapy Grade 3-Grade 5 treatment-related toxicities, and 72% of patients on KEYTRUDA plus chemotherapy Grade 3-Grade 5 treatment-related toxicities. With this data, we believe that we are on track to revolutionize the treatment of head and neck cancer with improved clinical outcomes and better tolerability. Furthermore, in October 2023, preliminary biomarker data from the VERSATILE-002 trial was presented at the European Society for Medical Oncology, or ESMO Congress 2023. The combination of PDS0101 and KEYTRUDA appears to be promoting a predominant TH1 immunologic profile that is associated with enhanced CD8 killer T-cell induction and activity. The combination also led to subsequent decreases in the population of CD8 killer T-cells in the circulating blood. We are encouraged that these observations align with other phase II studies, reporting that PDS0101 induced polyfunctional CD8 killer T-cells do not reside in the blood, but rather traffic to tumors. These data support the two-year 74% overall survival rates reported in VERSATILE-002. Beyond the VERSATILE-002 trial, our focus has remained on steadily advancing preparations for our phase III VERSATILE-003 trial. In October 2023, we announced feedback from the FDA regarding the amended investigational new drug application and thereafter, feedback on the final clinical trial protocol. We currently have up to 60 sites selected globally and are going through the qualifying process. As anticipated, the FDA-reviewed phase III clinical trial design has been pivotal to our business development discussions, which has yielded positive insights from prospective partners. Our clinical and medical teams are assessing final details of the trial, and therefore we anticipate VERSATILE-003 will now start in the first quarter of 2024. We'll keep you updated on our next steps as we progress toward trial initiation. Now, turning to IMMUNOCERV. In October 2023, data from the phase II clinical trial were featured in an oral presentation at the American Society for Radiation Oncology annual meeting, known as ASTRO. These data demonstrated that PDS0101, in combination with standard of care chemoradiotherapy, was associated with a rapid decline in HPV-positive circulating tumor DNA. At five weeks of treatment, ctDNA clearance of 92% was reported with PDS0101, whereas 53% clearance was observed in patients receiving standard of care chemoradiotherapy alone. These biomarker data support the 100% response rate in patients receiving PDS0101 and standard of care, which was reported at SITC 2022. As this trial continues to progress, we will provide further updates. Now shifting to our IL-12 fused antibody drug conjugate, known as PDS01ADC. PDS01ADC is a novel ADC, or antibody drug conjugate, that enhances the proliferation, potency, and longevity of T-cells and IL-12 in the tumor. Let's begin by discussing the compelling updated data from the National Cancer Institute-led triple combination trial that was reported on November 9. This study is a phase II trial of PDS0101, PDS01ADC, and an investigational ICI. This combination has undergone evaluation across multiple HPV-positive cancers, encompassing anal, cervical, head and neck, vaginal, and vulva cancers in two groups of advanced cancer patients. The ICI-naive group constituted patients unresponsive to standard of care treatments that have not yet received ICI therapy. The ICI-resistant group included individuals who had shown no response to multiple prior treatments, including ICI therapy. Regarding the ICI-naive group, the chart shows the confirmed objective responses reported in VERSATILE-002 and the triple combination based on investigator assessment, both shown in green, as well as published KEYNOTE-048 data. Notable is the objective response rate of 75% with the triple combination and 27% with the dual combination. With KEYTRUDA monotherapy and KEYTRUDA plus chemotherapy, the published objective response rates were 19% and 36%, respectively. The next figure contains updated survival data from VERSATILE-002 and the triple combination trial in green, as well as published data from KEYNOTE-048. What is notable here is the fact that despite the lower objective response rate with PDS0101 plus KEYTRUDA, the survival benefit seen with the PDS0101 plus KEYTRUDA combination, as well as the triple combination, appears to be similar, with 24-month survival rates of 74% and 75%, respectively. The triple combination also shows a compelling 3-year survival of 75%. These data suggest that PDS0101 may play a significant role in extending survival in the ICI-naive population, independent of objective response rate, while PDS01ADC appears to promote strong objective responses in this population. The median overall survival has not yet been reached in either the VERSATILE-002 or the triple combination studies. To contextualize, published data on standard of care immune checkpoint inhibitors, or ICIs, report that at 12 months, only 30%-50% of these patients would typically be expected to remain alive, and less than 30% of the patients could be expected to remain alive at 24 months. Therefore, survival associated with the PDS0101 combination regimen at two years for VERSATILE-002 and three years for the triple combinations is notable. Now, looking at the ICI-resistant group, where there's a significant unmet medical need and no FDA-approved product. These are the patients who have failed all treatment options, including ICIs. In these ICI-resistant patients with HPV-positive cancers, the reported median overall survival is only about three to four months. In the ICI-resistant patients, this slide shows that the published objective response rate with systemic therapies, including high-dose chemotherapy, is 42%. The objective response rate was 0% with PDS0101 plus KEYTRUDA in VERSATILE-002, 5% in patients who received PDS0101 with low doses of PDS01ADC and/or ICI therapy. and 63% in patients who received PDS0101, with initial high doses of PDS01ADC and ICI therapy. Again, these data appear to demonstrate the role of PDS01ADC in promoting strong and compelling objective response rates, even in late stage ICI-resistant cancer patients. Let's now take a look at the overall survival rate in ICI-resistant patients. On the slide, we will see that, irrespective of objective response rate, the PDS0101 containing therapies, shown by the green bars, provide durable survival results. Despite the lack of confirmed objective responses with PDS0101 plus KEYTRUDA, the 12-month overall survival rate was 56% for VERSATILE-002, and 72% in the triple combination. With systemic therapies, the published 12-month overall survival rate is 36%. This data provides compelling evidence regarding the role of PDS0101 in the survival of ICI-naive and ICI-refractory HPV-16-positive patients, and the potential role of PDS01ADC in further extending survival and also promoting objective responses in this population. This study provides compelling evidence that supports the potential synergy between our Versamune-based targeted T-cell immunotherapies and our IL-12 fused antibody drug conjugate, that provides the sustained presence of IL-12 in the tumor, thus providing further expansion and activation of the Versamune-induced multifunctional killer T-cells within the patient's tumor. We believe that this data supports broader application of this combination beyond HPV-positive cancer, and provides a unique potential to effectively address multiple advanced cancers in our development pipeline. As a reminder, a safety update for this trial was announced in late December 2022 in 50 patients. 48% of patients experienced Grade 3 treatment-related adverse events, or AEs, and 4% of patients experienced Grade 4-related adverse events. To put the safety profile in context, in the KEYNOTE-048 study, it is reported that the combination of KEYTRUDA and chemotherapy resulted in 72% of patients having Grade 3 through Grade 5 treatment-related adverse events. We are therefore pleased with the tolerability profile that is emerging for PDS01ADC, even when administered in combination with other oncology agents. As I mentioned earlier, to date, we have safety data from over 250 patients dosed with PDS01ADC. This provides further evidence that this novel modification of IL-12 may be effective in mitigating previously observed cytokine side effects while promoting improved clinical benefit, and further justifies its continued development by PDS Biotech. PDS01ADC is also being studied independently of the Versamune immunotherapies. The National Cancer Institute recently presented data for the ongoing phase II clinical trial of PDS01ADC, in combination with docetaxel chemotherapy in advanced metastatic, castration-sensitive, and castration-resistant prostate cancer patients at the Cytokines 2023 annual meeting. This trial is the first clinical study of an immunocytokine with docetaxel in prostate cancer. The study is investigating the safety, immune responses, and preliminary clinical activity of the combination in advanced prostate cancer patients. The trial evaluated three doses of PDS01ADC in combination with docetaxel, and showed that the combination was well tolerated at all tested doses, with less than 10% of patients having a Grade 4 toxicity. Most importantly, over 60% of patients had a prostate-specific antigen or PSA level reduction of greater than 60%, with some patients having a 90%-100% PSA reduction. As shown, reduced PSA levels were documented in all 18 patients. PDS01ADC activates T-cells, natural killer cells, and natural killer T-cells, while reducing the presence of immunosuppressive regulatory T-cells. As a result, we believe that we now also have an opportunity to apply PDS01ADC to advanced and difficult-to-treat tumors by combining PDS01ADC with standard of care chemotherapy and radiation therapy. PDS01ADC is also being investigated by the National Cancer Institute in a phase I/II study in patients with intermediate and high risk locally advanced prostate cancer in combination with radiation therapy. As mentioned previously, PDS01ADC is also being studied as a monotherapy by the National Cancer Institute in an ongoing phase II clinical trial in Kaposi Sarcoma. At PDS Biotech, we are highly optimistic about the potential of this novel PDS01ADC asset in cancer therapy. Switching now to preclinical development studies. The National Cancer Institute has developed a second novel approach to treating immune checkpoint inhibitor-resistant cancers by using Versamune-based immunotherapy and PDS01ADC, in combination with histone deacetylase or HDAC inhibitors, another oncology standard of care. The preclinical data were presented during the recently concluded 2023 annual meeting of the Society for Immunotherapy of Cancer, or SITC. In this preclinical study, superior antitumor activity was observed in ICI-resistant tumor models with a Versamune-based immunotherapy, PDS01ADC, and entinostat, a Class I HDAC inhibitor. This novel triple combination proof of concept study is under consideration as a potential approach for initial clinical studies of PDS0103 to treat MUC1-specific cancers. We are encouraged by the potential of this combination. The National Cancer Institute will lead this clinical trial under our established cooperative research and development agreement, and we anticipate that it will begin in the first half of 2024. PDS Biotech has had a fruitful quarter, and we are preparing to finish out the year strong as we move into 2024. To summarize, we hosted a successful KOL event where we announced positive, updated overall survival and safety data from the VERSATILE-002 trial and gained important insights from head and neck oncology leaders about the potential of PDS0101 in the treatment of HPV-positive head and neck cancer. Preliminary biomarker data presented at ESMO from the VERSATILE-002 trial supports the reported overall survival results. The biomarker data from the IMMUNOCERV trial, presented at ASTRO, demonstrates the role of PDS0101 in eliminating circulating tumor HPV DNA. The updated triple combination data demonstrates the role of PDS01ADC in promoting durable overall survival and objective responses, even in difficult-to-treat ICI-resistant patients. Data from the PDS01ADC and docetaxel trial presented at Cytokines demonstrated tolerability of the combination and encouraging PSA biomarker results and immune responses. With that, I'd now like to turn the call over to Matt to discuss the financial summary. Matt? Now turning to our financial results for the three months ended September 30, 2023. Net loss for the period was approximately $10.8 million, or $0.35 per basic and diluted share, compared to a net loss of approximately $7.4 million, or $0.26 per basic and diluted share for the three months ended September 30, 2022. The higher net loss this quarter was primarily due to costs incurred in connection with our research and development and clinical programs. Research and development costs, which includes clinical and manufacturing expenses for the quarter, ended September 30, 2023, increased to approximately $6.4 million, compared to $4.3 million for the same period of 2022. The increase of $2 million is primarily attributable to an increase of $1.3 million in clinical trial costs and $0.7 million in personnel costs, which includes $0.3 million in non-cash stock-based compensation. General and administrative expenses for the second quarter of 2023 increased to approximately $4.1 million, compared to $2.9 million for the same period of 2022. The increase of $1.2 million is primarily attributable to an increase of $0.7 million in personnel costs, including $0.5 million in non-cash stock-based compensation and $0.5 million in investor relations costs. Our cash and cash equivalents as of September 30, 2023, totaled approximately $54.3 million. We continue to be prudent with our cash expenditures, and we believe that with initiating the VERSATILE-003 phase III clinical trial in the first quarter of 2024, our available cash resources will sustain our operational and research and development endeavors into the third quarter of 2024. We expect to execute our current operational and research and development endeavors by obtaining additional capital, principally through entering into collaborations, strategic alliances, or license agreements with third parties and or public or private debt and or equity financings. We've had and continue to provide what we believe to be favorable development milestones to the market and have upcoming development milestones we believe may provide additional catalysts to investors. At this time, this completes my financial discussion. I would like to hand the call back over to the operator for the Q&A session. Operator? Thank you. At this time, we'll be conducting a question-and-answer session. If you'd like to ask a question, please press star one on your telephone keypad. A confirmation tone will indicate your line is in the question queue. You may press star two if you'd like to remove your question from the queue. For participants using speaker equipment, it may be necessary to pick up your handset before pressing the star keys. Our first question comes from the line of Louise Chen with Cantor Fitzgerald. Please proceed with your question. Hi. Congratulations on all the progress this quarter, and thank you for taking my questions. So I had a few questions for you. As you think about 2024 and we table set for next year, what are the key milestones, catalyst readouts that you think we should have on our radar? Secondly, how do you think about OpEx for fourth quarter 2023 and 2024 in light of the fact that you're going to start this VERSATILE-003 phase III? And the last question is: when do you think we'll see data on VERSATILE-003? Thank you. Louise, thank you very much for your questions. I'll answer two, and I'll hand over the OpEx to Matt. But in terms of the key milestones and catalysts as we move into 2024, as I mentioned, key will be getting VERSATILE-003 up and running. We also have announced and stated that we do anticipate and expect the final data readouts from VERSATILE-002 sometime in the second quarter of 2024. As I also just mentioned, we do expect to initiate the PDS0103 clinical trial in MUC1 related cancers early in 2024, at least in the first half of 2024. We also are hopeful that we will have the preliminary data from our neoadjuvant trial ongoing at the Mayo Clinic in early stage oral cancer, HPV-positive oral cancer, where we're looking at PDS0101, both as a monotherapy and also in combination with KEYTRUDA. We have not had any readouts from that study yet, and we're hopeful that we will get that in sometime the first half of 2024, based upon what we've been informed by the PI and their goal of presenting at an upcoming conference. And also, we do expect to have additional data readouts on the IMMUNOCERV cervical cancer trial. And so we do have a number of potential milestones coming up, as well as readouts for it. And we, as you know, we don't talk too much about the trials going on also at the National Cancer Institute. We had the readout from the docetaxel as well as the PDS01ADC. We also have those studies ongoing in early stage prostate cancer, locally advanced prostate cancer. We're hopeful that we'll see some data from that trial in 2024. We have the monotherapy trial going in Kaposi Sarcoma. Hopefully, we will see some data from that trial in 2024. And so I think we will have hopefully a pretty busy 2024, and hopefully we'll be able to provide quite a number of data readouts as we go through the year. In terms of the VERSATILE-003 trial, I think we'll have much more clarity on when we'll have the data readout. So as you know, when we will be able to provide the data readout will be at our first interim data readout. Now, when we get to the first interim data readout depends on the number of sites that we have open at the start, as well as the enrollment rates that we will encounter or that we'll be able to achieve as the trial goes initiates and progresses. What we are currently doing, as I mentioned, we have 60 sites that have been identified so far. The goal is to get to 100 sites. And what we are trying to understand now is how rapidly each site will come on board. And as we understand better how we will open the sites and the sequence of opening the sites and how many sites will be open at any particular time, we will then be able to provide a much more, a much more. We're much more confident in the timelines we will be able to provide you as to when we will get to that interim data readout. But we are working aggressively on that now and hopefully should be able to provide that information very soon. Matt, I'll hand over to you for the operating costs. Thank you, Frank. Louise, thanks for your question. I want to let you know that, you know, it's a good question. We've been—I would say we've been extremely prudent with the use of the company's cash and capital. When you look over the last probably seven quarters or so, we burned about a little north of $6 million per quarter. And with the significant number of studies that we have ongoing, not only the VERSATILE-002 trial, but also, the trials with the NCI, the ITs with MD Anderson, as well as Mayo, we've been extremely frugal, in our opinion, in how we manage these costs. But as we prepare to move forward into a phase III clinical trial, obviously those costs are going to increase. Now, from a perspective of OpEx, the administrative costs will grow slightly, but we could expect that the company will incur costs in R&D of, you know, somewhere around. Overall costs, I'm sorry, will be somewhere around between, you know, $12 million-$15 million once the study starts up, with some of that being front-loaded for the normal deposits that are needed to be made to get the contract CROs and the like set up. Which is why we, under the current circumstances of us looking at a trial beginning in Q1, we've got cash into Q3 of 2024, which also gives us additional time to go out and look for, you know, business development deals. We had the ferret data come out. We've had the Versamune NCI trial data come out. We've had the docetaxel data come out. We've had the KOL meeting. So there has been a significant number of data readouts, and we're hopeful that that will be a catalyst for potential business development deals as well. Thank you. Can I just ask you one follow-up question? So for fourth quarter 2023, then you would expect OpEx to be similar to third quarter, or would there be some ramp up for the start of the- There will be, there will be some ramp up in Q4 of this year. So we spent about $10.5 million in total in Q3. So my expectation would be around there or a little higher. Okay. Thank you. You're welcome. Thank you. Our next question comes from the line of Mayank Mamtani with B. Riley Securities. Please proceed with your question. Good morning, team. Thanks for taking my questions and appreciate the comprehensive pipeline update. So maybe a high-level question quickly for you guys. So given PDS0101 prolonged survival and, and the higher ORR you seem to have be driven by PDS01ADC, investors generally wonder if perhaps it makes sense to also evaluate triplet in first line, or, or should we think of triplet to be more in the ICI-resistant patients or, maybe even being HPV agnostic? Could you just clarify how you're thinking, you know, relative positioning of these two, programs? And then I have a couple of follow-ups. Frank, if you're speaking, you may be on mute. Thank you very much. Hi. Can you- Yes. So Mayank, I think, you are absolutely right. We have seen highly encouraging survival data with PDS0101, as well as PDS01ADC, as well as extremely encouraging ORR with the PDS01ADC. Now, we have certainly considered the application of the PDS01ADC in the earlier line, ICI-naive. However, after talking to key opinion leaders in the field, as well as the regulatory experts, it's evident that the survival and safety data generated with the doublet presents the most straightforward regulatory pathway, as well as the robust uptake, if and when it becomes standard of care. Right? With the doublet, will also enable a more rapid potential approval path for early, even early use. Now, when we look at the triple in the ICI-resistant population, it also presents the quickest path to approval and potentially application in multiple HPV cancer indications, as you mentioned, in essentially tumor-agnostic. This triple combination may then also subsequently find its way to an approval for use in ICI-naive patients. So this is something we have actually seriously considered, but after talking to the experts in the field, the two options we're taking now appear to provide the quickest path to rapid approvals and uptake. Understood. Thank you for that clarification. And then maybe, drilling down on the doublet trial protocol, are there any details on the SAP that you're able to share, in terms of the, you know, target OS differential you're going for against standard of care? I recognize you're, you know, talking about sites, but not specific patient numbers, but just sort of, it would be helpful to understand, you know, what sort of hazard ratio, what sort of delta on OS you're aiming for. And just a related question, your ESMO translational biomarker data was actually quite novel in context of demonstrating CD8 T- cell responses specific to tumor cells. I was wondering if there are any implications of that in terms of, you know, patient enrichment or response assessment strategies that you could deploy in your late-stage development? Okay, Mayank, a lot of really good questions. So let me start with the biomarker data. So with the biomarker data, as you did mention, we're looking at a number of novel approaches to really understanding and documenting how PDS0101 is working, and really documenting and clarifying the differentiation of our assets. So if you look at the data presented at ESMO, for example, looking at the polyfunctional CD8 T-cells, confirming increase in polyfunctionality was very important, but also understanding the kind of immunological profile that PDS0101 is promoting. For example, going from a TH2 biased to a TH1. TH1 being well documented to be better associated with strong CD8 T-cell responses, right? And also showing that we have potential exit of the CD8 T-cells from the blood to the tumor sites, right? Showing the decline in circulating peripheral blood containing CD8 T-cells. So we have that approach and that study in the PDS0101 program. Now, when you also look at what's been done in terms of biomarkers in the IMMUNOCERV study, right? Very complementary to what we've seen with the PDS0101 KEYTRUDA study. In the IMMUNOCERV study, what MD Anderson was looking at is circulating tumor DNA. Circulating tumor DNA is extremely important for a number of reasons, right? If you look at cancer today, most patients don't die from the initial tumor or the initial cancer. They often die from micrometastatic cancer that remains after the initial treatment, right? And so being able to essentially eliminate the tumors from the patient's body becomes extremely important, and how do you know that your technology or product is actually achieving that? What we have seen now with our circulating tumor DNA in that study is the strong potential for PDS0101 to actually dramatically eliminate and reduce and eliminate the circulating tumor DNA, right? At five weeks, 92% reduction versus 52% reduction with the standard of care. MD Anderson is extremely excited about that because they believe it has direct implications for patient survival and, very importantly, recurrence of the cancer, right? So that is, that is data that we will hopefully be expecting to see coming up in 2024, how that elimination of circulating tumor DNA correlates with recurrence of the cancer and survival of the patients. Now, what they also looked at, a very innovative approach using cervical brushing, to really quantify and understand the kinds of T-cells that are actually accumulating in the patient's tumors, right? So we talked about the CD8 T-cells in the blood and exiting the blood, but it's also important to understand what's happening in the tumor. And what they also showed was a really strong correlation between this elimination of circulating tumor DNA and accumulation, targeting accumulation of these CD8 T-cells within the patient's tumor, right? So again, very different. To date, most of our peers have looked at T-cells in the circulating blood, looking at things like interferon gamma. But what we are showing here is that these T-cells generated by the Versamune technology actually do target and accumulate in the patient's tumors, right? So again, we have very complementary studies which are in agreement with each other, which have given us a really good picture of how and why we've seen the results we've seen in these patients today. Now, if you go to the triple combination, very similar studies have been performed by the National Cancer Institute in the triple combination. Again, showing that very strong correlation between induction of HPV-16 specific T-cells and the clinical responses, and also showing that this triple combination, in addition to inducing strong tumor-specific multifunctional T-cells, also induces an inflammatory immunological profile, which is strongly believed to suppress the tumor's ability to hide from the immune system, right? So now we're getting all the information that that helps us better understand how and why we're seeing the kinds of results we've seen today in these patients, even in the very difficult to treat patients. So now coming to your earlier question, which has to do with the design of the VERSATILE-003 trial. Now, we have not made details of the clinical design public yet, but I can give you some insight into how we're thinking about this. The delta today is quite significant when you look at the delta of what we've seen are the two-year results versus what we see in the published data. We know that by far exceeds what we'll have to achieve for approval. But as a risk mitigation strategy in terms of our statistical design, what we are also looking at is we're also saying, "Well, let's assume PDS0101, the patients in our control arm taking KEYTRUDA, will do much better than KEYNOTE-048," right? And so in terms of our endpoints for the control arm, we're anticipating that they'll be higher than KEYNOTE-048. Patients oncologists are getting more used to administering KEYTRUDA. They're getting better understanding of which patients may respond better, and so we have to assume that those patients are going to do better than has been published today. What we are also assuming in that design is that our patients in the study, at multiple sites all over the world, will not do as well as we've seen in VERSATILE-002. So we are also reducing that target, and that risk mitigation allows us to overpower the study based upon what we've seen today and mitigate the risk that we will not get to that clinical endpoint, right? So we're taking those strategies into consideration just based upon the really large delta we've seen today, allows us to narrow that delta, but also be reasonable in terms of trial size and the power of the trial to successfully achieve those primary endpoints of overall survival. Mayank, I hope that answered your question. Yeah. No, very, very comprehensive, very helpful. And lastly, for Matt, just quickly on the strategic collaboration discussions, are you able to describe qualitatively interest from strategics on doublet versus triplet, and how maybe, you know, recent triplet data may have informed those discussions? And also, you know, there's a full data set from your doublet expected in second quarter. Would they wanna see that mature analysis before, you know, transacting? Or, like, kind of just lay out what some of the variables that are there, that impact a discussion like that. Thanks for taking my question. So, Mayank, actually, I'm not going to be able to go into- You wanna take that one first? Yes, I'll, I'll take that one. Yes. So Mayank, as you know, I, I won't be able to go into very specific details as to what we are discussing. However, the data that we have today has been very helpful in clarifying certain things. So one of the key things that I mentioned over the last couple of earnings calls has been the fact that we are waiting to see the data from the VERSATILE-002 refractory arm. That data was very important because it was key in giving us insight into the specific role of PDS0101, or the contribution of PDS0101, in extending life in head and neck cancer patients. And so looking at that combination of PDS-0101 and Keytruda in patients who have failed checkpoint inhibitors, the majority of which we know were on Keytruda, and still being able to extend the, those patients' lives significantly, was very important for us to demonstrate and to get, to get potential partners also comfortable that, okay, PDS-0101 is actually biologically active in this population, and even seeing this extension in even a much more difficult to treat population. So that, that was, that was key. It was also important for us in the triple combination trial, as I mentioned previously, for us to have that understanding of what PDS-0101 is doing in that combination. Because a lot of the questions we receive, both from investors and prospective partners, is: Well, in the triple, how do we know which of these co-components is working and what is contributing to what, right? So now the role of PDS0101 becomes very clear. But with the data we have today, right, we also now see the critical role of PDS01ADC. And so now both components, both drugs, have very clearly shown their biological activity. And what was also very important is if you look at VERSATILE-002, right, refractory arm, no IL-12, 0% confirmed objective response. If you add a low dose IL-12, 5% confirmed objective response. If you go to a high dose IL-12, 63% confirmed objective response. Very clear in terms of what's happening with the IL-12, right? So all this data that is now available provides not just PDS, but potential partners with confidence in the biological activity of our, of our drugs. Right? In terms of discussions, I'll say there are no issues with the current protocol, right? As you know, we have alignment with the FDA on the path forward, but what's happening with these discussions is not at all uncommon, and we believe that it is prudent to at least evaluate suggestions that a serious potential partner may have, even though there are no guarantees that a partnership will result when all is said and done, right? But there are a number of typical things that we'll typically want to evaluate at this case, and we would not do this for every prospective partner or suggestion we receive, however. So I hope that gives you some flavor of what the data we've seen today and how it's impacting discussions that we are having. It does. Thank you for taking your questions, and look forward to future updates. No problem. Thanks a lot. Thank you. Our next question comes from the line of Joe Pantginis with H.C. Wainwright. Please proceed with your question. Hi, good morning, everybody. Thanks for taking the questions. Two questions, please. So first, for 0101, wanted to ask about currently what you have ready to go, followed by your intermediate near, near-term needs and intermediate needs with regard to manufacturing. And then the second question is a little bit of the off the beaten path here, 'cause, it's been nice to hear such the encouraging, data updates from an 0101. But I wanted to ask about 0202 and the universal flu vaccine. You are sitting on what we consider to be a very strong asset profile and the data that you've accumulated to date. So other than the rhetorical answer of financial resources, what could you envision being a development plan for that asset? Thanks. Hey, thanks a lot, Joe. I'll start with the first question in terms of what we have ready to go with PDS0101. So with PDS0101, we have done all the tech transfer. The material has been scaled up to our commercial process, and the phase III clinical product has already been successfully manufactured and released. So in terms of clinical product that has been scaled up to the final process and has been successfully manufactured, we are there today. So the material is ready to go. We don't have any additional needs from the perspective of PDS0101 materials in order to run the phase, to run the phase III clinical trial with either program, VERSATILE-002 or the triple combination. With PDS0202, as you mentioned, this is a program that we're quite excited about. Today, our resources, financial resources, are really focused on the oncology programs. However, we have made significant progress also with this program. As you know, the data was presented in September at the European Influenza Conference, the data from ferrets. Right, ferrets being the gold standard for preclinical studies. So it was very important to be able to demonstrate that we can replicate the data that was generated in the mouse models in the ferrets, which are closest to humans in influenza. And again, all that was done has been done successfully. We've shown very similar levels or identical levels of broadly reactive neutralizing antibodies against multiple strains of the flu. That was shown successfully in ferrets. We also showed successful prevention of viral replication in the lungs when the animals were given lethal doses of the H1N1 virus as well as protection against infection in the ferrets also. So we have shown, we have shown very good translation. Now, from PDS's perspective, for us, this is not surprising because, again, even in our oncology products, we've shown very good translation from preclinical models to human, right? And so we expected this. The NIAID is extremely encouraged by the data that they've seen today, and so we have had some discussions. We are still hopeful that we will get some notification sooner or later regarding the next steps. What we would envision or what we would like to see would be for this to go into at least a phase I/II human clinical trial sometime next year and start generating the human data that can also replicate the kinds of broadly reactive, neutralizing antibodies that we're seeing in the animal models in humans. Hopefully, provide very important data on safety. As you know, with preventive vaccine, safety is extremely important. We've seen very good safety profile today with PDS0101, so we do expect to see very similar safety with the preventive vaccine. And then hopefully, pending on when in the year it's done, get some data on actual prevention against against infection with the flu. So we're very. We, we're really hopeful. We still are in very, very good discussions with NIAID. They've indicated that this is something they would like to move forward, and so we are waiting to learn what the next steps will be and when those next steps will start. Appreciate the color, Frank. No problem. Thank you. Ladies and gentlemen, as a reminder, if you'd like to join the question queue, please press star one on your telephone keypad. Our next question comes from the line of Jim Molloy with Alliance Global Partners. Please proceed with your part, with your question. Hello, this is Laura on for Jim. Thank you for taking the questions, and congrats on all your progress. So you mentioned an upcoming trial for your preclinical PDS0103 candidate for, you know, the first half of next year. What are any other updates that you have for your preclinical PDS0102 and PDS0104 candidates? Hi, Laura. Thanks for your question. So with PDS0103, as I mentioned, the goal is to start in the third quarter, in the first half of next year. And so that is going to be done under our collaboration with the NIH. Right now, we are finalizing the CMC section. We are finalizing the animal studies and looking at the new triple combination, which is potentially going to be very likely the path we go down. That's being evaluated now in specific tumor models that we would want to include in the IND filing. So we are working towards an IND filing, hopefully in Q1 of next year, to get this into the clinic, hopefully by the second quarter of next year. With PDS0102, we are also working now on the tech transfer, and the formulation development has been completed. Preclinical work has been completed with PDS0102. And just to remind the audience, who may still be on PDS0102, specifically addressing prostate cancer. So I'm sure you can see how that potentially lines up with what we're doing with docetaxel. There is the potential that we could include that to make a new triple combination, but the goal here with that program is to get that dual combination as rapidly as possible to commercialization. But there's potential for expansion in terms of even more difficult or latest treat cancer patients and decline of circulating tumor DNA using that PDS0102 asset, in which the target is TARP, T-A-R-P. T-A-R-P has been found in about 90% of prostate cancers at all stages of the disease and about 50% of breast cancers. So that's an asset that we do anticipate, hopefully getting into manufacturing sometime next year in 2024, to allow us to start to evaluate that asset also probably later in the year. But we will provide updates regarding what the, what we're doing with that program, what the potential partnerships, how we're going to move that forward. We'll provide some of, some more of those details later as the year goes by in 2024. PDS0104, we have not yet made any additional progress with PDS0104. We've really concentrated on PDS0101, 0102, and 0103 at this point, as well as PDS01ADC. Got it. Thank you for the clarity. And also just one more question. Alongside the data presented for IMMUNOCERV, for your other, you know, investigator-initiated trial of PDS0101, this with the Mayo Clinic, do you have any estimates as to when you might get data announced here? No. So with the Mayo Clinic, starting with the Mayo Clinic, as I mentioned, that's, you mentioned that that's another investigator-initiated trial. It's evaluating the early stage HPV-16 positive oral cancer in neoadjuvant setting. We have been informed, as I mentioned, by the PI, that they hope to present preliminary data at the scientific meeting in the first half of 2024, and so we'll keep you updated as we learn more as to what conference that would be and what the exact timing would be. But we are hopeful that we'll see some data, we'll see the first preliminary data from that trial, hopefully in the first half of 2024. And with IMMUNOCERV, with IMMUNOCERV, the investigators are extremely encouraged with the data that they've seen today. Based on what we've been told by Dr. Klopp of MD Anderson, who leads this trial, she's actually planning on submitting interim results of the study for scientific publication, and particularly the recent circulating tumor HPV DNA outcomes reported at ASCO, the previously reported tracking and accumulation of multifunctional CD8 T-cells in the tumors, and she also intends to update clinical response and survival data. So we are hopeful that we'll get an additional update on that trial in the near future. Understood. Thank you for taking the question. Thanks a lot. Thank you. There are no other questions at this time. I'll turn the floor back to Dr. Bedu-Addo for any final comments. Thank you very much. So thank you to all for participating in our third quarter earnings conference call today. The progress made this quarter has been truly exciting. We remain enthusiastic about what lies ahead for the rest of this quarter and into 2024. We have made significant strides towards our objective of developing groundbreaking therapies that transform cancer treatments. We are confident that our efforts will positively impact these patients with critical unmet medical needs, leading to longer lives and improved quality of life. We appreciate your continued support and eagerly anticipate updating you on our accomplishments. Thank you very much again, and have a wonderful day. Thank you. This concludes today's conference call. You may disconnect your lines at this time. Thank you for your participation.
