Good afternoon, and thank you for participating in the GeoVax corporate update call. Last year, and more specifically, during the fourth quarter, we successfully advanced our developments, focused on the two Phase 2 clinical stage products while also advancing other critically important initiatives. Today, we'll discuss the progress status and plans related to Gedeptin currently in development as a therapy against advanced head and neck cancer and GEO-CM04S1, our next-generation COVID-19 vaccine. Our goal is to develop innovative cancer therapies and infectious disease vaccines, addressing critically important unmet medical needs, pursuing initial indications that support expedited registration pathways. We anticipate worldwide development, commercialization and distribution via business partnerships and collaborations. Following my comments, Mark Reynolds, our CFO, will provide an update on our financials and then your questions will be addressed. At year-end, we announced the closure of enrollment for the Phase 1/2 trial of Gedeptin among advanced head and neck cancer patients. This initial targeted patient population represents those who are in end-stage care, the 15,000 U.S. and 400,000 worldwide. These patients represent a critical unmet medical need. Many are unable to swallow food and have difficulty speaking. Typically, they have exhausted existing therapies and standard of care and are receiving palliative care. Our goal has been to provide an improved end-stage quality of life in these patients by shrinking and/or eliminating various targeted tumors and to provide clinical evidence supporting advancement of this therapy in earlier-stage disease. As you may recall, this trial was funded by the FDA under the Orphan Drugs clinical trials program. Last July, initial clinical data results were presented at the AACR AHNS Conference in Montreal. That presentation noted that administration of Gedeptin was shown to be safe and feasible reflecting stabilization and/or reduction in size of treated tumors. We expect to report the final results of this trial during first half 2024, followed by discussing our plans for further evaluation of Gedeptin in patients with advanced head and neck cancer. Our strategy also considers Gedeptin therapy for earlier-stage HNSCC with less tumor burden, including a role similar to neoadjuvant or cytoreductive radiotherapy in combination with checkpoint blockade inhibition. We also anticipate discussions with the FDA during 2024 related to an expedited path to registration. The vast array of unmet medical needs within oncology represents significant opportunities for GeoVax to advance novel approaches, addressing various cancer patient needs worldwide. We refer to Gedeptin as tumor-agnostic, meaning that this mechanism of action will enable us to address a variety of solid tumors, both cancerous and benign. We hold worldwide rights for all indications of this technology, and we are participating in various oncology and partnering conferences and some of which we will present conducting clinical data and with others to conduct partnering discussions. GEO-CM04S1, our next-generation COVID-19 vaccine aims to provide a more practical public health friendly COVID-19 vaccine solution than that offered with currently approved vaccines by stimulating a robust and durable immune response across multiple virus variants as a result of targeting both the antibody and cellular arms of the immune system and through the use of a proven safe and efficient replication-deficient vaccine delivery pathway. This is critically important in addressing the high-risk populations of immune compromised individuals for whom the current vaccines in monoclonal antibody therapies are inadequate. The immune profile generated following receipt of GEO-CM04S1 also positions it well for more general use as a heterologous booster to current mRNA vaccines, providing a more robust durable functional response against emerging variants, potentially without the need for the continuous vaccine reconfiguration that appears necessary with the mRNA vaccines. Three Phase 2 clinical trials are underway with CM04S1, two of which address the high-risk populations of immunocompromised patients. The other Phase 2 trial is a evaluating our vaccine as a booster following prior receipt of an mRNA vaccine. We hope to demonstrate that our COVID-19 vaccine substantially addresses the current unmet needs among the millions of immunocompromised patients while also demonstrating the vaccine as a more robust, durable universal booster for the current authorized vaccines. Last September, we completed enrollment in our Phase 2 trial assessing CM04S1 as the booster for the mRNA vaccines. This trial involves 63 healthy adults who had previously received the Pfizer or Moderna mRNA vaccine. The immunological responses measured throughout the study include both neutralizing antibodies against /SARS-CoV-2 variants and specific T cell responses. Earlier this month, we reported positive interim data from this trial, indicating no serious adverse events and statistically significant increases in neutralizing antibodies against multiple SARS-CoV-2 variants ranging from the original Wuhan strain through Delta in the highly virulent Omicron SBB 1.5, as well as demonstrating robust cellular immune responses. Additional testing against the current variant of concern, the JN 1 variant is currently underway. Final results from this trial are anticipated during the fourth quarter of this year, reflecting the 12-month monitoring of these patients. Previously, we've discussed in the U.S., there are approximately 15 million immunocompromised individuals. Worldwide, they are estimated over $240 million. Such populations include those with various blood cancers, renal disease, autoimmune diseases such as lupus, they include transplant patients and others with disease or therapy-induced immunosuppression. Many of these patients are limited in their ability to respond adequately to the approved mRNA vaccine, placing them as significantly increased risk of severe COVID-19 infection hospitalization and potential death. Recently, it was reported in JAMA in February 15 that the number of immunocompromised adults in the U.S. has been updated, indicating a population of $23 million versus the previous estimate of $15 million. There is a major critical need for next-generation COVID-19 vaccines to support such individual, and we believe that CM04S1 is the leading next-generation vaccine in clinical development in support of the needs of immunocompromised patients. During 2023, initial data from stem cell transplant trial was presented at several international conferences, including the World Vaccine Congress in Washington, D.C. In addition, results were published this past September in the peer-reviewed journal vaccines. These findings demonstrated robust immunogenicity illustrating the vaccine ability to strongly induce both antibody and T-cell responses essential for confirming protection, particularly in immunocompromised individuals. The vaccines article also highlighted the unique feature of CM04S1, providing protective immune levels from the ancestral Wuhan strain all the way through what I mentioned earlier, the highly virulence Omicron XBB1.5 variant. Initial patient enrollments into this trial occurred at the City of Hope Medical Center in California. More recently, however, additional sites have been added as we seek to accelerate the pace of trial enrollment. In addition to the patients initially enrolled from City of Hope, there are now four additional sites actively recruiting patients in this critically important Phase 2 trial. The four expansion sites include the Fred Hutchinson Cancer Center in Seattle, University of Massachusetts Medical Center in Worcester, Mass, Wake Forest Baptist Medical Center in Winston-Salem of North Carolina and Eastern Carolina Medical Center in Benson, North Carolina. While we are currently focused on optimizing patient enrollment from these sites, we've seen considerable interest, both domestically and internationally and participating in this clinical study. Following the initiation of patient enrollment in the immunocompromised CLL trial last August, this investigator-initiated trials continue to recruit and enroll patients more recently expanding to additional City of Hope locations. The trial is designed to evaluate CM04S1 among approximately 80 CLL patients directly comparing with the Pfizer-BioNTech mRNA vaccine. Typically, these patients are unable to generate adequate levels of protective antibodies following mRNA vaccination due to their underlying hematologic malignancy placing them at extreme risk of developing clinically severe COVID-19. As a consequence, many of these patients remain homebound more than three years since the pandemic began. We are optimistic that CM04S1 can offer these individuals the protection from these buyers that they so desperately need. Results from an interim analysis of the ongoing trial are anticipated during the first half 2024. Relative developing CM04S1 immunocompromised patients we believe that an opportunity exists for an expedited regulatory path due to our focus on such high-risk unserved populations. Now I'd like to comment regarding Project NextGen. Last April, the White House announced this $5 billion initiative to follow on from operation Warp Speed. Seeking COVID-19 vaccines with enhanced breadth of protection against variants and improved durability, particularly insisted in novel vaccine candidates already in clinical trials. We believe that CM04S1 is a prime example of the desired next-generation COVID-19 vaccine. Regarding Project NextGen, we continue with active discussions related to the formal participation in this program. Of the $5 billion set aside for funding there remains over $3 billion still to be awarded. Beyond noting that we remain in active discussions and negotiations regarding participation, we can't comment further at this time. Finally, related to CM04S1, we anticipate partnering and collaborations and additional clinical and research efforts and in support of worldwide commercialization and distribution. Active initiatives are underway in this area. Overall, we're addressing opportunities that provide us a basis for achieving leadership within those targeted patient areas and commercial markets. Our current clinical stage products, Gedeptin and CM04S1, are focused on patient populations currently unserved by existing vaccine vendor therapies. We believe that the potential of achieving product leadership in addressing the therapeutic and vaccine needs of these respective populations exist and we're focused in that area. Also, GEO [MVA], our vaccine against Mpox and smallpox is intended to disrupt an existing global monopoly in that important area, providing us a leadership position as the first U.S.-based supplier of such a vaccine. We're confident that we're on the course that will build significant shareholder and stakeholder value while delivering critically important differentiated products to improve lives worldwide. During this year, we will report further progress and results from our CM04S1 Phase 2 programs. And for Gedeptin, we expect to report the final results from the current trial and our plans with the expanded Phase 2 trial. We also expect to report further plans regarding next steps related to evaluating Gedeptin as combination therapy used in conjunction with immune checkpoint inhibitors. Relative to our MVA vaccine against Mpox and smallpox, we anticipate reporting our regulatory path and plans related to advancing that product towards registration. Finally, we anticipate further updates related to our advanced MVA manufacturing process targeted to enable GeoVax to effectively produce and distribute MVA-based vaccine in response to real-time market needs worldwide. To summarize, our various clinical stage products, Gedeptin, CM04S1 and MVA represent clinically important areas of medical needs, largely unserved by current products and standard of care. We are pleased with the consistent encouraging results we're seeing from our clinical trials. More we believe the expedited path to registration are feasible for these products. From a potential commercial perspective, these product opportunities represent an estimated annual U.S. revenue potential of almost $30 billion. Now that's not a sales forecast, but rather a reflection of the significance of the need to address these critically important areas. Expanding this to a worldwide basis in conjunction with partners and collaborators adds to the confidence that we have relative to the outlook for GeoVax our shareholders and stakeholders. Now I'd like to turn the presentation over to Mark Reynolds, GeoVax's Chief Financial Officer, for a review of our recent results and financial status. Mark?
