Thank you, Operator. As it's been mentioned, I'm Tom Eagles, the CEO of AIM Immunotech. And at AIM Immunotech, our motto for the company is Immunology for a Better Future. We're working not just for the financial rewards that come from the type of research and development we do, but primarily to bring not just hope, but a cure to people with lethal malignancies and diseases such as long COVID through our experimental drug Ampligen. We're on target in these serious disease areas where there's a complete unmet medical need. And in doing that, again, we're trying to create a better future for those, many of whom have no hope right now. With regard to our quarterly call today, those of you who attended our last call, which was just a month and a half ago, recognize that we've had significant improvement over the past 18 months in terms of progress in our clinical trials, especially in our key priority areas of pancreatic cancer, advanced recurrent ovarian cancer, and long COVID. Now, I want to talk a little bit about our late stage pancreatic cancer program because we've had a tremendous amount of data come in through our early access part of that program, which establishes a very clear measure and de-risks our future clinical work because in those subjects, we're approaching 50 subjects at this point, we're seeing clear evidence of progression-free survival and overall survival. And that is a cancer that is a malignancy which is projected for 2023 to be one of the top causes of cancer-related deaths in the world. So it's a big market. Advanced recurrent ovarian cancer, our data that we've gathered over the past several months, going back to April of last year, has a very strong indicator of Ampligen's potential as a therapeutic in a number of different solid tumors. In addition to the progress that we made in the clinic, we had a number of different regulatory approvals of INDs authorizing us to go forward with placebo-controlled clinical trials, for example, in long COVID. expressing chronic fatigue-like symptoms. And for a randomized controlled phase two in pancreatic cancer. So we're making strong regulatory progress that parallels these advances in the clinics. And we've also made some structural changes. We have made a world-renowned biotechnology pioneer, W. Neil Burnett, as the chairman of our scientific advisory board. And Nancy Bryan has joined our board of directors. She has a deep and strong pharmaceutical industry background, including a lot of activity that we think will be very valuable in mergers, acquisitions, and licensing. So we've improved the depth and quality of our management team significantly. Now, as to our pipeline, if you go to our website, you can get the details for this, but we have prioritized in repurposing Ampligen several years ago into oncology, we have prioritized two areas of clinical development that are extremely important for the future of our company. First is pancreatic cancer. We have an early access program with almost 50 subjects having been treated. This was a use authorization by the Dutch government, which has been underway since late 2016. And in that program, we have demonstrated progression-free survival and overall survival based on comparison with well-matched historical controls, both in locally advanced pancreatic cancer as well as metastatic pancreatic cancer. advanced recurrent ovarian cancer. And as you know, late-stage pancreatic cancer is almost like a death sentence. Well, advanced recurrent ovarian cancer is very much the same. And in advanced recurrent ovarian cancer, we're involved in a phase two at the University of Pittsburgh, combining R-drug Ampligen with Merck's drug Pembrolizumab, also known as Keytruda. And in that study, we're seeing remarkable results from the preliminary data that was posted, and we're expecting a protocol-driven interim report in just a few months, and it's our hope that that preliminary data will be sustained in this data report set by the protocol, because the preliminary data, which was published at the AACR convention as an abstract, a late-breaking abstract, shows that Ampligen combined with pembrolizumab and cisplatin-sensitive patients, is creating significant survival advantages, including complete responses and significant partial responses in a disease where that is rarely seen at all. So we're very excited about that. And our long COVID program, we've got an FDA authorization to commence that. We have numerous sites that are in the final stages of getting up and running and we hope to see the not only those sites open but very rapid enrollment and dosing of subjects with the site Selection that we have we have a reasonable expectation That will have all of these subjects treated by the end of this year or certainly in the first quarter of next year So I'm very excited about where we're at today, and I'd like to take a moment now to introduce our scientific officer. One of the things that we've done recently, too, is we've promoted Dr. McAleer to scientific officer for the company, and he's going to do a deep dive into some of these programs. Take it on, Chris.

Thank you, Tom. I'm happy to be here. As Tom just pointed out, pancreas cancer is our primary focus, and That is in large part due to the positive data that was collected as part of that early access program in the Netherlands. As you recall, the EAP was ampligen as a singular monotherapy following fulfironox in patients with both locally advanced pancreatic cancer and metastatic pancreatic ductal adenocarcinoma. And that original data published in the journal Cancers highlights the the improvements in the progression-free survival and overall survival over historical controls, and this graph is a reminder of that positive data. And these promising results have led to the design of both our AMP270 locally advanced study as well as the study in metastatic cancer that I'll be discussing shortly. As you will, as we'll be opening the Erasmus Medical Center as part of both AMP270 and the DORPAC study, We expect any new patients to be enrolled in each of those two studies, and we will leave this early access program open as an option for patients that don't qualify for either ongoing study. And while these data have led to the design of these two new studies, the EAP has continued to enroll additional subjects beyond that published in cancers. And we expect to have an updated analysis, including updated Kaplan-Meier plots for progression-free and overall survival. during our Q2 call, and I'll be really excited to show that data. It's quite promising. In addition, the subsequent analysis of patient blood samples has revealed differences in gene expression profiles between patients who had stable disease after six weeks of treatment and those who had progressed. And as an example of that, those with stable disease expressed markers of immune upregulation, such as IRF4, LTB, and CD83, But more important to that, it's given us insight into differential gene regulation in those who have progressed, such as ARG1 upregulation, which may mediate T cell suppression, and ATG12 upregulation, which is implicated in autophagy. And armed with that information, we can continue to advance our understanding of Ampligen's mechanism of action, as well as find additional potential targets for combinatorial therapies to ultimately improve patient outcome. In addition, the data that's most striking to me is that patients taking Ampligen have shown an increase in Ki67 positive populations of both cytotoxic T lymphocytes and T helper cells, as well as an increase in the population of CD69 positive cytotoxic T lymphocytes and T helper cells, indicating that the Ki67 positive, indicating that these T helper and T lymphocytes can continue to proliferate, but the CD69 expression showing that they have the ability to be activated. And so while we need to explore these findings further, it points to the potential of Ampligen to sustain the pool of T cells and mitigate T cell exhaustion that has been known to occur with checkpoint inhibitors. And that data has me extremely excited. And the press release and a link to that data presentation will be forthcoming as as these data were recently presented by our colleagues at Erasmus Medical Center at the 2023 Pancreas Club meeting in Chicago. And these data have me excited because they give me ever more confidence that AMP270, that the AMP270 study in locally advanced pancreas cancer and the DORA PANC study in metastatic PDAC will be successful. And so I want to take a moment to address the AMP270 study in a little further detail. We currently have the Gabriel Cancer Center in Camden, Ohio open, and they are actively screening patients. Enrollment at that site has been slower than we expected, but we are working diligently to open additional sites, as well as looking at different methodologies to increase advertisement for the Gabriel Center sites that hopefully increase their enrollment. A site initiation visit will be occurring at the University of Nebraska Medical Center next week. and we expect that site to be open and enrolling patients before the end of May. Shortly after that, we will have an additional site initiation visit at Virginia Mason Medical Center in Seattle. And beyond that, we are in open contract negotiations in some degree or another with approximately 20 different sites and plan to have additional sites in the US and Europe opening by year's end, and that does include the Erasmus Medical Center in the Netherlands. With that being said, do still expect the first patient to be enrolled in Q2, but because control patients in this particular study do not receive dosing, it is possible that the first patient, the actual first patient dosing will not be until Q3, but I am cautiously optimistic with the additional sites opening and in the very near future that we may still reach that timeline. I want to talk about the investigator-sponsored DORPANG study, which will combine AstraZeneca's Dervalumab with Ampligen following Fulfironaz. This is a Phase I-II study to investigate the safety and efficacy of that treatment. As you guys have probably been aware, Ampligen has shown a high combinatorial benefit with checkpoint inhibitors, specifically with the PD-1 inhibitor Keytruda. in both triple negative breast cancer as well as advanced recurrent ovarian cancer. We believe the combination of the immune modulating properties of Ampligen and the ability of Ampligen to maintain the pools of T cells that I discussed previously, we combine that with a known high PD-L1 expression in pancreas cancer that Dervalumab should combat. Those together make for a very intriguing synergistic combination that we believe is likely to show very great promise in extending both progression-free survival and overall survival in those patients with metastatic cancer, pancreas cancer, that we are all aware are desperate for a cure. There are some minor comments to the ethics committee that need to be addressed, but otherwise the major hurdles for the initiation of this study have been ironed out. We have speculated previously that this study will commence in Q4 of 2023. But again, I am cautiously optimistic about our chances of actually beating that projected timeline. And to the end of further investigating the mechanism of Ampligen's efficacy in treating cancer, such as further advancing the research from the EAP I discussed earlier, and as well as providing a molecular biology lab space to initiate investigations and other indications, including other cancer indications, I have been able to secure a small lab facility at the Sid Martin Biotechnology Hub that is associated with the University of Florida, their UF Innovate program. This space will allow us to update and improve protocols and methodologies pertaining to the CMC, the chemistry manufacturing control section, of what we expect to be our future NDA in pancreas cancer. This lab will supplement the chemistry lab that we have in New Jersey, and it will provide us with the necessary lab space to solicit and acquire NIH funding, which I am actively pursuing to help offset costs at a relatively low burden to the stockholders. I personally think that the approximately $20,000 per year that we're spending for this facility is a bargain price to give us access to almost everything we need, including wet lab space, analytical equipment, microscopes, incubators. the infrastructure of a world-class research facility, including biohazard waste removal and IACOC access, just to name a few. And I think this acquisition will help to advance the fundamental biology and chemistry behind Ampligen and to help ensure that we are prepared for regulatory scrutiny when that day comes. And while oncology is our primary focus, I would be remiss to not briefly mention the advancements we have made in the post-COVID condition of fatigue. The AMP518 study is intended to enroll 80 patients, 40 control and 40 ampligen treated in a randomized, double-blind, placebo-controlled fashion. The primary outcome of that is the PROMIS fatigue score with other secondary outcomes, including some exploratory biomarkers, such as immune cell monitoring and advanced exploratory biomarker panel analysis that we hope will shed light on disease etiology, as well as provide some insight into responder population characteristics. We are hopeful that this responder population will be high, and that hope is based off the preliminary data that we have collected as part of the AMT511 study amendment that we made to treat patients with post-COVID conditions. As you may recall, the small population of patients that we had showed improvements in their general fatigue, their ability to exercise, as well as decreases in the post exertional malaise that is associated with that exercise. And in addition, these patients demonstrated improvements in their focus, their concentration and their memory. And we have currently agreed upon budgets and clinical trial agreements with 10 sites and expect to have all those contracts through the legal process and signed within the next two to three weeks. Our expectation is to ship drug in the first two weeks of June. and have all 10 sites open and treating patients in mid to late June. Our hope and expectations from the site feasibility questionnaires is that enrollment will take no longer than three to four months, and the last patient will be enrolled in Q4. And that's a broad overview of the scientific and clinical advancements we've made thus far, and I'll hand it back to Tom to discuss the company finances.
