Michael Tardugno: Thank you, Kim. And good morning, everyone. It's good to be here with all of you. Joining me today are Jeffrey Church, our Chief Financial Officer then Sebastien Hazard, our Chief Medical Officer. Dr. Hazard will speak about Imunon-001, IL-12 immunotherapy and its anticipated place in the treatment of advanced ovarian cancer. In addition, Dr. Kursheed Anwer, our Chief Science Officer, who joins us from the HudsonAlpha Institute in Huntsville, Alabama, where our research center is. Dr. Anwer will be available during the Q&A session at the end of our prepared remarks. But first, I'm sure you're all aware of the departure of Corinne Le Goff earlier this month to pursue other business opportunities. We wish her well and are grateful for her leadership and her contributions that she made to Imunon during her tenure.
I just want to reassure you, however, that her departure in no way impacts our plans for growth and we remain wholly committed to advancing our two key technology platforms, that's TheraPlas and PlaCCine. We remain on track to complete our Phase 2 OVATION 2 study with IMNN-001, which is based on the TheraPlas platform, and to initiate our Phase 1 study of IMNN-001, our seasonal COVID-19 vaccine concept, based on our PlaCCine technology. Our strategy for the development of these product platforms remains unchanged as well. From the OVATION 2 study, we expect to report top line data in mid-2024. Based on our interim data and preliminary conversations with FDA, Dr. Hazard will be drafting the protocol for the Phase 3 study soon. He'll be speaking more about this in a minute.
Meanwhile, this past month, we announced the submission of an IND application with the FDA for 101. Following acceptance by the agency, we expect to begin enrolling patients in this Phase 1 study in the second quarter of this year. And we're ready to go. We have two sites identified -- the two sites identified, that's Beth Israel in Boston and DM Clinical Research in Philadelphia. Both institutions have submitted to the IRB our protocol. They've been conditionally approved pending FDA acceptance. The biological safety committees at both institutions have approved the protocol and our contracts in place or in process. We're ready to go. So we look forward to the agency's agreement with the IND submission and look forward to initiating the study.
I'll talk some more about the vaccine program, but first I'd like to turn the call over to Dr. Hazard. Sebastien?
Sebastien Hazard: Thank you very much, Michael. Hello, everyone. Before I discuss our vision for 001, I want to review some of the interim data we generated and share some considerations on what a pivotal trial could look like should the Phase 2 data hold up. As you know 001 is our DNA-based IL-12 immunotherapy. OVATION 2 is a randomized study evaluating 001 for the perioperative treatment of newly diagnosed, advanced ovarian cancer patients. It's being tested in combination with standard-of-care chemotherapy. September 22, we reached full enrollment of 113 patients, and a year later, in September 23, we reported a set of interim data showing promising progression, free survival, and overall survival. In the intent to treat population, the data show the delay in disease progression or death in the treatment arm for more than three months.
On preliminary overall survival data, followed a similar trend, showing an approximate nine months improvement in the treatment arm over the control arm. This data, particularly OS, still needs to mature to confirm this robust efficacy signal. We also reported, for the first time, data on a subset of patients treated with PARP inhibitors. When we began OVATION 2 study, PARP inhibitors were not yet part of the first line maintenance treatment in ovarian cancer. Now they form an important part of the patient's treatment plan. A subgroup analysis of patient who received post-chemo maintenance therapy with PARP inhibitors suggests an even larger clinical benefit. In this subgroup, the median progression free survival was 23.7 months in the arm with 001 versus 15.7 months in the control arm or eight months longer.
In addition, the median overall survival in the control arm was 45.6 months and not reached in the 001 arm. Although these data are from a small number of patients, they are intriguing. Safety analysis continue to show good tolerability of 001 in this setting. So, here are our thoughts on this program right now. We think we may very well have in our hands the first immunotherapy effective for the treatment of ovarian cancer. This is made possible by the TheraPlas technology allowing the durable production of IL-12 by the tumor microenvironment, as shown in our Phase 1 OVATION 1 study. So far the clinical data with 001 from OVATION 1 to the preliminary data of OVATION 2 confirm 001’s activity. We believe that the positioning of 001 in the perioperative treatment of ovarian cancer patients is very important.
In addition to the lack of new options for these patients, this is the stage of the disease when the locally administered immunotherapy can have the most impact by harnessing the local immune system in the tumor microenvironment. Assuming enough maturity on the PFS data around midyear and similar efficacy results, the next step is to submit a registration study plans to the FDA. Several considerations are in discussion internally. One being the inclusion of patients receiving bevacizumab during the perioperative setting. Bevacizumab, as you know, is frequently used in the perioperative setting in about approximately 50% of the patients. And these patients were excluded from OVATION 2. The combination of bevacizumab and 001 has also shown synergistic efficacy in preclinical experiments and the ongoing Phase 2 study done with Breakthrough Cancer Foundation will provide safety data on the combination.
This is important as it may allow 001 to offer even more clinical benefit in synergy with [Technical Difficulty], it would also help with the study enrollment by making the trial more attractive to sites using Bevacizumab for most of their patients. Another consideration is the focus on the tumor with homologous recombinant deficiencies or HRD who are the most likely to be exposed to a PARP inhibitor in maintenance. We may introduce in the study design the possibility to test 001 efficacy in this subpopulation, representing around 40% of the newly diagnosed ovarian cancer patients. Now, enrollment in our second Phase 2 study in collaboration with Breakthrough Cancer Foundation is ongoing. The first four patients have been treated at the University of Texas MD Anderson Cancer Center.
And in the first quarter of ‘24, we announced that Memorial Sloan Kettering has joined the study. This study is evaluating 001 in combination with bevacizumab or Avastin. It is expected to enroll 50 patients in Stage 3/4 ovarian cancer at several sites. Initially, this randomized study will allow to confirm the safety of the combination of 001 with bevacizumab and later provide proof-of-concept for this combinations. The trial's primary endpoint is detection of minimal residual disease or MRD, by second-look laparoscopy, and the secondary endpoint is progression-free survival. Initial second-look laparoscopy data are expected within a year following completion of enrollment. And final PFS data are expected approximately three years following enrollment completion.
This trial will include translational endpoints to better understand the impact of 001 combined with bevacizumab on the tumor microenvironment and assess other methods like ctDNA to measure MRD. An important trial to better understand the somewhat under-evaluated neoadjuvant stage of ovarian cancer. We will keep you updated as sites continue to be added. So with that review of our ovarian cancer program, I turn the call back over to Michael.
Michael Tardugno: Thank you, Sebastian. And I just want to say for the record, Dr. Hazard has joined us recently. And he brings with him a wealth of experience in clinical research, ovarian cancer, and regulatory affairs that's beginning to show a great deal of promise, we are delighted. I can't say enough for the impact that you've had in your very short period of time, and I'm sure the company and our shareholders will benefit from your expertise.
Sebastien Hazard: Thank you.
Michael Tardugno: Thank you, Sebastien. So I want to talk a little bit more about the durability. You're going to hear that through the course of our conversation this morning. A durability is a key characteristic and an advantage of our technology over similar product candidates. Our technology allows for the durable production of a protein in the body for IMNN-001, as illustrated by Dr. Hazard, this allows the prolonged exposure of the tumor microenvironment to IL-12. For a vaccine against a pathogen, this durability allows sustained production of the target antigens that we expect will provide protection from the pathogen well beyond the approximate six months that is provided by the mRNA vaccine platforms. So with that, I'm not the expert here, so Dr. Anwer, you're on the line. Would you -- could you tell us a little bit more about the mechanism and our experience so far with this durability characteristic?
Kursheed Anwer: Sure, Michael. This is Kursheed, hello. As you said, Michael, the durability of an agent, whether a therapeutic or a vaccine, is an important attribute of a drug. For oncology drugs such as IL-12, a persistent local level at tumor site is imperative to keep the pressure on the tumor, and that is determined by the stability of the drug after injection and persistence after cell entry. The same is true for vaccine. The only difference is that in vaccine setting, your product is a pathogen -- antigen. Now, to answer your question, the mechanism of our approach for durable expression of a therapeutic molecule in our IL-12 product or a pathogen, antigen in our vaccine product is addressing the bioavailability and persistent challenges.
First mechanism that addresses the product stability after administration is the use of our proprietary delivery system that protects the DNA from degradation, so there's higher bioavailability. Second, the DNA, unlike protein or mRNA, has longer residence time in the cell, and hence the production of protein antigen or therapeutics last longer. So, in a nutshell, our mechanism of durability, whether a therapeutic or a vaccine, is increasing the bioavailability through the delivery system and longer residence time in cell through the use of DNA. Really, those two key aspects are part of the mechanism.
Michael Tardugno: Thank you, Kursheed. Dr. Anwer will be on the line to answer questions at the end of our prepared remarks. So now let's continue our discussion of PlaCCine, our proprietary vaccine based on DNA plasmid that promotes the expression of pathogen, antigens delivered in our proprietary non-viral synthetic delivery system that Dr. Anwer just spoke about. We're delighted to report that the filing of an NDA for 101 with the FDA, we are proposing a Phase 1 clinical trial as a seasonal COVID-19 booster vaccine. This 24 subject proof-of-concept study is expected to begin enrollment in the second quarter of 2024 following acceptance by the FDA, which we are hopeful will be quite soon. The dialogue between Dr. Hazard and the agency has been robust.
Responses to their question have been very timely, so things are moving quite well. The primary objective of this study in healthy adults is to evaluate the vaccine's safety, tolerability, and neutralizing antibody response. We'll also evaluate the durability of response and durability, a key characteristic. The second objectives are to evaluate the ability of IMNN-101 to elicit the antibody immunoglobulin G or IgG as it's referred to, in T cell activity and their durability. Based on preclinical data, durability of immune expression is expected to be superior over published mRNA vaccine data. 101 for this study has been designed to protect against Omicron XBB1.5 variant of SARS-CoV-2 in accordance with the FDA's guidance published in June 2023.
As you may recall, we've generated some compelling preclinical data on the attributes of this vaccine. Most importantly, immunogenicity and better protection than 95%, sorry protection better than 95%. We also demonstrated superior shelf life at 12-months at refrigerated temperatures and at least one month at 90 degrees Fahrenheit from body temperature. These characteristics suggest superior commercial handling and distribution properties when compared with the more fragile messenger RNA vaccines, as well as greater manufacturing flexibility, compared with the viral or other DNA vaccines or protein vaccines, PlaCCine vaccines have the advantage in T cell responses, safety, delivery compliance, or manufacturing flexibility. So I'm going to turn back to you, Dr. Anwer.
Why are we so confident about the stability of our product? Can you give us a little bit of contrast and compare with messenger RNA?
Kursheed Anwer: Yes, sure. I mean, we all know that the mRNA vaccines came out very strict storage conditions requirement, actually at minus 70 degree freezers. You have to keep it there in pharmacies during transportation. You have to use minus 70 degrees. That's extreme cold temperature and the country, even developing countries, much less the under developing countries, just not equipped with that kind of temperature provision. So it's a problem disseminating the vaccine. So relative to mRNA, the DNA is more stable, and it could last at working temperature. There's a refrigerated temperature, which almost every pharmacy has for a very long period of time, because it's more stable than mRNA and plus, as I had mentioned before, the use of a protective delivery system also provides more stability.
So it's just the intrinsic nature of DNA versus mRNA and the use of synthetic delivery system that limits the degradation of DNA. That really keeps distinguishing feature of our vaccine over mRNA in terms of temperature stability. And actually, even at 37 degrees, we have seen for a month stability. So imagine that pharmacy nurses take it out or delivery people, they don't have to worry about, you know, putting it -- discarding it after a couple of hours if its not, you know, if the temperature -- if the duration goes beyond two hours. So I think we feel confident in that sense. We have addressed that critical issue in vaccine distribution and storage.
Michael Tardugno: Thank you, Kursheed. Again, Kursheed used 37 degrees centigrade. And I was talking about 90 degrees Fahrenheit, both are equivalent for handling for at least one month. And that really makes the vaccine stable during its preparation for administration to patients at temperatures that are very realistic, and particularly in some of the more demanding third world countries. Again, Dr. Anwer will be available for questions at the end of our prepared remarks. Following the Phase 1 study in assuming 101 performs as expected, we have no reason to believe it won't. We'll look to partner out this program for further development and to expand on the platform. For those of you who may be concerned that we are a little bit late to the party, I'd also like to add, assuming success in the clinic, as we are pointing out, the superiority of this technology is the potential to be vitally important to the government, the defense agencies in particular, and of course to the medical community as a means to address rapidly evolving and newly emerging viral pathogens with pandemic potential.
So with that, I'll turn the call over to Jeffrey Church for a discussion of our financials. Jeff?
Jeffrey Church: Thank you, Michael. Details of Imunon’s 2023 financial results are included in the press release we issued this morning and in our Form 10-K, which we filed before the market opened. Imunon ended the year with $15.7 million in cash and investments. Net cash used for operating activities was $18.9 million for 2023. This compares to $23.1 million in the prior year. This decrease is primarily due to a one-time payment of $4.5 million in interest expense in the first quarter of 2022, resulting from the sale and subsequent redemption of $30 million of convertible preferred stock. Cash used in financing activities was $3.8 million this year. That resulted from the payoff of the Silicon Valley Bank loan, which amounted to $6.4 million, offset by sales under the company's at-the-market equity facility of $2.6 million.
As we have in the past, we will continue to focus on strong cash management. Let me now turn to a review of our financial results. Imunon reported a net loss for 2023 of $19.5 million, $2.16 per share. And this compares with the net loss of $35.9 million or $5.03 per share last year. Operating expenses were $21 million for 2023, a decrease of $4.4 million or 17% from 2022. Now, breaking down these operating expenses by major line item, research and development expenses were $11.3 million, very consistent with the levels we reported last year. More specifically, R&D costs associated with the development of 001 to support the OVATION 2 study, as well as the development of the PlaCCine DNA vaccine technology platform, were $6 million in 2023, and that compared to up $6.1 million for 2022.
Costs associated with the OVATION 2 study, the clinical development costs, were $1.2 million this year, that's down from $1.5 million in the prior year. And this decline was due to the completion of enrollment, as Dr. Hazard indicated in September of 2022. Our CMC costs, manufacturing costs, increased $2.2 million for 2023 from $1.2 million for 2022, due to the development of in-house pilot manufacturing capabilities for DNA plasmids and nanoparticle delivery systems this year. Costs associated with the Phase 3 OPTIMA study were de minimis this year, compared to a million dollars in 2022. Our clinical and regulatory costs were $1.8 million this year, compared to $1.9 for 2022. General administrative expenses were up $9.7 million for 2023, compared to $13.7 million for 2022.
This $4 million decrease was primarily attributable to lower non-cash stock compensation expense, lower employee-related costs, primarily lower legal costs as we've resolved many of the issues that had arisen with the Phase 3 trial with THERMODOX. Lower costs for DNO insurance also contributed to this decrease. Subsequent to the end of the year, we announced that we had received $1.3 million in net cash proceeds from the sale of our unused New Jersey net operating losses. These NOL sales are a very nice, non-dilutive funding source, which further strengthens the company's balance sheet. Other non-operating income this year was $200,000, that compares to other non-operating expenses in 2022 of $12.5 million. Investment income this year from our short-term investments was $1.2 million, compared to $0.5 million last year.
As I mentioned earlier, in June of 2021, we had entered into a loan facility with Silicon Valley Bank. We used the proceeds from that facility to retire a previous loan facility with Hudson Technology Finance Corporation. In connection with the SBB loan facility, we incurred $200,000 of interest expense in 2023, that compared to $500,000 in 2022. In the second quarter of 2023, we terminated and paid off the Silicon Valley bank loan facility. We had to pay some early termination and end-of-term fees and we recognized a $300,000 loss on the debt extinguishment. I think more importantly, so the big driver in last year's non-operating expense was in primer charge of $13.4 million that we took in writing off some in-process assets or in-process R&D assets and offsetting that was a non-cash gain of $5.4 million due to the write-off of a earn-out milestone liability, because the requirements had not been achieved.
And then lastly, as I mentioned earlier, we had a one-time $4.5 million interest in offering expenses resulting in the sale and then subsequent redemption of the preferred stock. Our cash utilization for 2024 is approximately $18 million, providing us with a runway that takes us pretty much through the 2024 time period. With that financial review, I'll now turn the call back to Michael.
Michael Tardugno: Thank you, Jeff. As always, a lively discussion of our financials. As you know, we filed an S1 in January of this year, the goal of which was to raise capital in support of our ongoing research programs. In testing the market Imunon like virtually all other non-revenue micro-cap biotechs, was presented with terms that we felt were unacceptable and unfair to our shareholders. So consequently we have chosen to defer financing until there are more favorable market conditions for the company. Doing so, however, is not without a plan. We have taken a responsible step to implement a cash conservation program. Deferring some of our non-essential programs and reducing our headcount footprint just makes sense. So our goal is to ensure that we have cash through the just discussed milestone readouts of our two clinical trials.
I trust that you will agree that we have been and are acting in the best interests of our shareholders, our employees, and our commitment to medical research. In closing, my prepared remarks, I want to emphasize that your company has a deep and capable management team that is keenly focused on harnessing the power of the immune system. Our goal is to provide more potent and durable immunity for millions of people with cancer or infectious diseases, while creating significant value for our shareholders in a place of work that our employees can be very proud of. With that, I'll open up the questions -- open up the call to your questions, operator?
