Thank you, Kim. And good morning, everyone. Today, joining me is Jeffrey Church, our Chief Financial Officer. In addition, Dr. Khursheed Anwer, our Chief Science Officer will be available during the Q&A session at the end of our prepared remarks. As I have discussed during previous calls, Imunon's growth and development is dependent on four pillars. The one I'd like to spend most of our time on today is the development of our PlaCCine prophylactic vaccines modality as an out licensing and partnership opportunity. PlaCCine is our proprietary mono-or multi-cistronic non-viral and synthetic DNA technology for the expression of pathogen antigens. It is currently being evaluated in preclinical studies for the development of next-generation vaccines. We have made exceptional progress advancing this technology as a Prophylactic Vaccines modality with important features, both as a commercial product platform and as a potential solution to addressing the next pathogens of interest. I will review some of our most recent preclinical data with PlaCCine, which suggests this asset has been derisked and is performing as we anticipated. During the quarter, Dr. Anwer presented results from preclinical studies in a PlaCCine COVID-19 vaccine at the Vaccine Technology Summit Conference and 2023 Virus and Cells Gordon Research Conference in Barcelona that demonstrated characteristics that address the limitations of current commercial vaccines by offering enhanced breadth of protection to emerging variants, persistence and robust cellular immunity, as well as stability at workable temperatures. Importantly, humoral immune responses specific to the SARS-CoV-2 spike antigen were persistent over a 14-month post-vaccination period, while the T-cell responses from PlaCCine COVID-19 vaccines after 14 months were higher than a commercial mRNA vaccine. In another mouse study, the humoral response to a single dose of a commercial mRNA vaccine plateaued within 14 days after vaccination while the response continued to increase over time with a PlaCCine vaccine, demonstrating improved durability. We believe that our DNA Tested Vaccine will provide greater protection against, reinfection, hospitalization or death. More recently, we have shown that PlaCCine is stable for at least 12 months at refrigerated temperatures, and for at least 1 month at room temperature. I can't emphasize enough how important these attributes are to a commercial vaccine product. Especially as many new pathogens may arise in geographies where there are challenges with refrigeration storage and distribution networks. In addition, our ability to rapidly switch out antigens and load [ph] multiple antigens into the same vaccine should be instrumental in addressing the spread of disease. Beyond the development of a next-generation COVID-19 booster vaccine which I will come back to in a minute, we at Imunon are interested in developing the PlaCCine modality across many pathogens of interest, like [inaudible] viruses or Arenaviruses viruses, where a data-based approach may be beneficial. Today, the U.S. and global public health policy and commercial vaccine manufacturers continue to play catch up with the reoccurrence of existing infectious disease spread and new emerging pathogens. Haemorrhagic fever, which are posed by viruses like Lassa, Marburg or Ebola are prime examples and are among the most serious threat stress to public health, both in the endemic regions of West Africa and worldwide due to high mobility and mortality rates, and these viruses cause lethal haemorrhagic fevers in several cases and are classified at risk such that need to be handled in biosafety level 4 facilities. And there are also potential biodefense spreads which is used as biological weapons against civilians. So, let's now turn to IMNN-001, our first Sanofi vaccine designed as the next-generation COVID-19 booster. All the pre-clinical studies in mice and NHPs have supported the development of pre-IND application that we submitted earlier this year to the FDA. We have just received the written response from the FDA. And I am pleased to tell you that the FDA provided encouraging feedback on our data and clinical development plan. Which gives us comfort that we are well on track to submit an IND in the first quarter of 2024 and enter the clinic soon thereafter. The IND will be for a proposed Phase I/II program, which is designed to provide proof of principle in humans. The FDA also confirmed that the plug-and-play strategy for our platform was acceptable. So this confirms the flexibility and the versatility of our modality, which allows for the rapid production and department of any vaccine by simply changing the antigen coding cassette. IMNN-101 is a Moderna COVID-19 vaccine candidate of the Omicron XBB1.5 variant as per the FDA recommendation. You remember that the FDA VRBPAC, the Vaccines and Related Biological Products Advisory Committee met on June 15 this year to discuss and make recommendations for SARS-Cov-2 strains for updated COVID-19 vaccine for use in the United States beginning in the fall of 2023. For the plug-and-play model, using the Plasmid DNA backbone, has shown excellent results, not only in COVID-19 strength, but our early work also suggests a PlaCCine vaccine could be useful in monkeypox know also as Mpox, Initial data appear to confirm the validity of PlaCCine as a platform with broad applicability. Mice immunized at the 0 and 14 with an Mpox vaccine initiated three separate hematological responses associated with the virus. And we also have generated immunological responses against flu and arenaviruses in preclinical work. Last quarter, I mentioned that we are developing two more modalities as a logical expansion of our prophylactic vaccine modality. FixPlas concerns the application of our DNA technology to produce universal cancer vaccines, also called tumor-associated antigen cancer vaccines. We have initiated preclinical work to develop a Trp2 and [inaudible] tumor-associated antigen cancer vaccine in melanoma, which we call IMNN-201. This new modality is based on antigen selection and optimization along with the option to include a potent immune modifier on a single nucleic acid factor. This represents a promising strategy to induce a specific and long-lasting immune response against tumor antigens. We have completed our initial proof of concept study, working in announced __ model, to potential cost selecting benefits, multivalent trip II bivalent trip II NY-ESO-1 vaccines. We are very happy with the results as the fixed class vaccination, followed by a tumor challenge, delayed the tumor growth and improved survival. Now the therapeutic studies evaluating the strategic benefits of our vaccines and consisting of a tumor challenge followed by the vaccination are ongoing and will be completed in the second half of the year. And we are also in early discovery of our fourth modality IndiPlas for personalized neo-antigen cancer vaccines. I'd like now to touch on IMNN-001, our DNA-based immunotherapy for the localized treatment of advanced ovarian cancer currently in Phase II development. Recall that last September, we reached full enrollment of 110 patients, and we expect to report an additional set of interim, more mature data in the second half of 2023. Enrollment with our study with Break Through Cancer is now open at MD Anderson, and the Break Through Cancer Foundation is working to add more sites. This study, as you remember, is looking at IMNN-001 in combination with AVASTIN. As part of our strategy to reduce reliance on outsourced manufacturers, in June we unveiled our new CGMP clinical materials production facility on the Hudfeild Alabama Campus of the HudsonAlpha Institute of Biotechnology. The facility will support R&D efficiencies and lower development costs for infectious disease and cancer vaccines and non-viral data-based immuno-oncology therapies. This new capability complements our existing CGMP quality control facility for testing clinical products at the Hudsfeild site. We have designed and built our own manufacturing capabilities to produce GMP-grade plasmid DNA and DNA facilitating agents to support Phase I/II studies with our PLACCINE infectious disease modality and our IndiPlas and FixPlas cancer vaccine modalities. The PLACCINE DNA and DNA activating agents are key components of the final vaccine formulation with JMP fill-and-finish carried out at a CDMO partner site. Our scientist can now select any protein from the human or pathogen proteoms to be engineered. Our existing labs also have the ability to conduct testing and run experiments in a variety of animal disease models. These internal capabilities will allow us to control both, the cost and the process. I will turn the call over to Jeff Church now, who will discuss our financial results. Then I'll come back and provide a review of upcoming milestones and activities. Jeff.
