Thanks Rob. Good morning, everyone, and thanks for joining us to review our financial results for the fourth quarter of 2023 and also to hear some very exciting recent updates. Then we'd be pleased to take any questions. First, I'll summarize some of our key activities for the fourth quarter of ‘23 or in some cases shortly thereafter. On October 2, 2023, we ended enrollment in our Phase IIb clinical trial of ibezapolstat or IBEZ, our lead antibiotic candidate for the treatment of patients with C. difficile infection or CDI. On November 2, 2023, we reported top line data from the Phase IIb clinical trial including overall results from the full Phase II study, demonstrating and ibezapolstat clinical cure rate at end 10 days oral treatment or EOT of 96%, 25 of 26 patients, which included 100% cure in Phase IIa and 94% cure in Phase IIb compared with vancomycin control arm the standard of which was 14 for 14 or a 100% at end of treatment and 94% was sustained cures. No safety concerns were reported in either arm of the Phase IIb clinical trial and ibezapolstat was well tolerated in all patients in both the Phase IIa open-label trial and the Phase IIb vancomycin control segment. In consultation with our scientific advisors, the company determined that based on review of aggregate blinded data, the Phase IIb vancomycin control trial segment was terminated early due to success showing high observed clinical cure rates with no emerging safety concerns, clinical comparability was established. We also stated at that further data would be provided as it becomes available on secondary and exploratory endpoints for the Phase IIb trial segment, including sustained clinical cure data at 30 days after EOT and extended clinical cure data 94 days after EOT as well as comparative data on the impact on the patient's microbiome. On December 11 ‘23, we announced the sustained clinical cure data. These data showed that in the Phase IIb trial segment 100% or 15 out of 15 of our advantaged patients who were cured at EOT remained cured with no reinfection 30 days later, while vancomycin experienced a reinfection rate of 14.3%, 2 of 14 patients were reinfected. On January 17, 2024, we announced positive comparative microbiology and microbiome data for the ibezapolstat in CDI patients from the Phase IIb clinical trial segment. Ibezapolstat to outperformed vancomycin showing eradication of fecal C. difficile at day three of treatment in 15 of 16 treated patients versus vancomycin, which had eradication of fecal C. difficile in just 10 of 14 treated patients. Additional data from the Phase IIb clinical trial showed ibezapolstat but not vancomycin consistently observed and allowed regrowth of key gut bacterial species believed to confer health benefits including prevention of recurrent C. difficile infection. We anticipate that additional data from the secondary and exploratory endpoint will provide further favorable separation these two therapeutic options in our Phase III clinical trial program and ultimately in the marketplace if approved. Additional analysis, regarding other secondary and exploratory endpoints will be forthcoming as data become available. We remain particularly excited about the dual impact of ibezapolstat to treat acute C. difficile infection while appropriately managing the long-term care of each patient's microbiome, which we believe is exceptional for antibiotic therapy. Having robust preclinical -- clinical and manufacturing data to date, we submitted a formidable information package in early February to FDA along with a request for an end of Phase II meeting, which was granted by FDA on Feb 26, and is scheduled to occur in April. We anticipate discussing our Phase III clinical trial mandate at this meeting and would anticipate documented meeting minutes from FDA sometime in the second quarter this year. We also announced that the European Medicines Agency approved their application to be designated as a small to medium sized enterprise or SME in Europe, which provides for certain benefits including fee reductions and other support from the European Medicines Agency for seeking a marketing authorization in Europe. In November, 2023, we filed an amendment to our shelf registration statement with the Securities and Exchange Commission and put up a $17 million at the market or ATM facility with Alliance Global Partners acting as sales agent to the company. Proceeds from the ATM will be used for general corporate purposes going forward, including our plan Phase III clinical trial mandate. In October, 2023, at ID Week, Dr. Kevin Garey presented on our behalf with selective spectrum of activity data from our Phase IIa clinical trial. Many of you may recall, Dr. Gary is Professor and Chair University of Houston, College of Pharmacy and the Principal Investigator for our microbiome aspects of the ibezapolstat clinical trial program. Also at ID Week, Bob DeLuccia, our Executive Chairman, presented our new class of novel DNA pol IIIC inhibitors in our preclinical pipeline at the symposium entitled new antimicrobes in the pipeline. Now that's a lot of activity to digest. So I'll summarize further as to where we are today. As we speak, we're preparing to advance ibezapolstat into Phase III clinical trials and anticipate a favorable outcome from our upcoming FDA meeting regarding readiness to proceed and also to obtain agreement on the regulatory pathway for a new drug application filing for marketing approval in the U.S. once Phase III is completed. We've also officially started the regulatory process in Europe will add other territories to the list later this year. The Phase III trials will include U.S. and international sites to enhance overall enrollment and to support international regulatory filings for marketing approval. This will save us a lot of time and money and allow us to expand our ultimate commercial reach. To ensure Phase III clinical trial and enrollment as quickly as possible, we're adding substantially more clinical trial sites, way above the number we used to conduct our U.S.-only Phase II trials. We're now getting our arms around the costs and time lines, but our plan is to conduct the required two Phase III registration trials consecutively not concurrently given the size of our company and need to use our financial resources most efficiently. The time line for conduct of our Phase III trial is not a concern since ibezapolstat will have a rolling 10 years of regulatory exclusivity in the U.S. from the FDA approval date with similar legislation in Europe, the U.K. and Japan. We will continue to seek strategic transaction for the company, including a potential partner for the further development and potential commercialization of ibezapolstat as well as a potential sale merger third-party ex U.S. territorial or licensing arrangement or our strategic transaction alongside in parallel with our preparation for Phase III clinical trials. At this time, we have no commitments from potential partners or others to provide the company with capital, but we started this initiative only recently in February after our Phase IIb data was released. So basically, we have two formidable plans going forward, and we're equally excited about partnering M&A and Phase III enrollment as next steps over the next 12 months. As we've consistently reported, ibezapolstat continues to outperform in a series of potentially life-threatening infectious disease called C. difficile that the U.S. CDC categorizes as an urgent threat and there's a need for new classes of antibiotics for initial treatment but also has a low incidence of recurrence. Ibezapolstat also has FDA Fast Track designation for treatment of C. difficile infection. Additionally, we believe ibezapolstat, if approved, could make a favorable impact by reducing the cost burden of current C. difficile infection in our U.S. health care system, which is estimated at $4.7 billion annually. We do believe the best is yet to come. And now back to our CFO, Rob Shawah to guide you through the highlights of our financial results for the fourth quarter and full year 2023. Rob?
