Thank you, Rob. Good morning, everyone. Happy St. Patrick's Day. Thank you for joining us on this morning's conference call, to review Acurx's financial results. During today's call we will review our financial results for the fourth quarter and year ended December 31, 2021, as well as some key corporate highlights, and then we'd be pleased to take any questions. In the fourth quarter, we commenced enrollment in our Phase 2b clinical trial of our lead antibiotic candidate, ibezapolstat in patients with C. difficile infection. The Phase 2b clinical trial is a one-to-one randomized, not inferiority, double-blind trial of oral ibezapolstat compared to oral vancomycin, the standard of care to treat C. difficile infection, in a total of 64 patients. The primary endpoint of the Phase 2b trial is clinical cure of the C. difficile infection at day 12 end of treatment, and the secondary endpoint is sustained clinical cure measured at the day 38 follow-up visit. In addition, we have an exploratory endpoint comparing the impact on the microbiome, between the ibezapolstat arm and the vancomycin arm of the trial. Additionally, in the event non-inferiority of ibezapolstat of vancomycin is demonstrated further analysis will be conducted to test for superiority. The Phase 2b clinical trial will include up to 16 U.S. trial sites with enrollment expected to be completed in the second half of 2022. We reiterate that with the closing of our IPO in June 21, we have more than enough cash to complete the Phase 2b trial as well as to allocate resources to continue the development of ACX-375 C, our second DNA polymerase 3C inhibitor that is at the lead optimization stage of preclinical development. Other key highlights from the yearend December 2021 include the following. In November 21, we initiated a laboratory study entitled effective ibezapolstat versus comparators on the microbiome in vitro and ex vivo analysis. We're doing this through our collaboration with Dr. Kevin Garey, Professor and Chair, University of Houston, College of Pharmacy, and the principal investigator from microbiome aspects of the ibezapolstat clinical trial program. The objective of this study is to expand upon our quite positive Phase 1 and Phase 2a microbiome data by comparing microbiome changes associated with ibezapolstat to other antibiotics used to treat C, difficile infection, including fidaxomicin, vancomycin and metronidazole. This laboratory study is being conducted using an in vitro gut model that mimics human gastrointestinal physiology. Additional data on the favorable effect of ibezapolstat on the gut microbiome was developed and presented at three prominent international scientific conferences during 2021, first in June 21 at the World Microbe Forum, we presented an eye poster and abstract with data from the Phase 1 healthy volunteer trial, using a novel analysis technique showing beneficial anti recurrence changes in the gut microbiome when compared to vancomycin. Our scientific advisors suggest that these data may be predictive of lower risk of C. diff recurrence or reinfection. These results were presented by Dr. Kevin Garey, who we already mentioned, and who is the principal investigator for microbiome aspects of the ibezapolstat clinical trial program. Second in October 2021 we presented a scientific poster and abstract with additional data from the ibezapolstat Phase 2a trial in patients with C. diff infection at the Infectious Disease Society of America IDWeek 2021 scientific conference. Specifically, Dr. Garey presented newly available data from our completed Phase 2a clinical trial in a scientific poster. Dr. Garey noted that favorable microbiome changes in these patients with CDI including overgrowth of actinobacteria and firmicutes virus species were observed in patients during therapy with ibezapolstat and that the results begin to confirm the microbiome effects seen in the Phase 1 healthy volunteers. Accordingly in our scientific advisor's opinion, use of ibezapolstat may very well be beneficial to the microbiome and these results are predictive of beneficial patient outcomes in our late stage trials, including anticipated low recurrence rates. Third, in November 21, Dr. Garey presented additional microbiome data from the completed Phase 2a trial at the 9th Annual International C. diff conference. These data demonstrated complete eradication of colonic C. diff by day three of treatment with ibezapolstat as well as the observed overgrowth of healthy gut microbiome, actinobacteria and firmicutes virus species both during and after treatment. Very importantly, emerging data showed an increased concentration of secondary bio acids, which is known to correlate with a low risk of reinfection. Moreover, a decrease in primary bio acids in the favorable increase in the ratio of secondary to primary bio acids provides more scientific evidence, suggesting recurrences may be very low in future trials. These presentations are available on our website at acurxpharma.com. We remain particularly excited about the dual impact of using ibezapolstat to treat the C. diff infection, while appropriately managing the long-term care of each patient's microbiome, which we believe is exceptional for antibiotic therapy. Other recent publications from 2021 include an article published in Nature Biopharma on October '21 titled Advancing a promising Antibacterial against C. Difficile. In August 2021 Health Holland awarded a grant of approximately $0.5 million to Leiden University of Medical Center to further study the mechanism of action of pol IIIC inhibitors in a consortium partnership with Acurx. This innovative research entitled Bad bugs, new drugs, elucidation of the structure of DNA polymerase IIIC of multi-drug resistant bacteria in complex with novel classes of antimicrobials, and will study three-dimensional structures of DNA polymerases and their binding interaction with Acurx's product pipeline, including ibezapolstat and 375. The antibacterial molecular target of a Acurx's pipeline of DNA pol IIIC inhibitors has been clinically validated by ibezapolstat's recent completion of a Phase 2a trial in patients with C. difficile infection. The research outcome is intended to accelerate lead product candidate selection for our ACX-375 program for systemic treatment against a wide variety of problematic resistant bacteria, including MRSA, vancomycin-resistant enterococci and drug-resistant Strep Pneumoniae. These are bad bugs, which the WHO, CDC and FDA all include as high-priority drug resistant gram-positive pathogens, where new classes of antibiotics are sorely needed. This project was initiated by Leiden University of Medical Center in September 2021, and emerging data are expected to contribute to the 375 development program. In terms of finance matters, highlights from 2021, include the following. The company consummated its IPO in June '21, raising gross proceeds of $17.25 million. The closing of the IPO included full exercise of the underwriters over-allotment option on the closing date. We are pleased to report that in November '21 Maxim Group initiated independent research coverage on Acurx through its research analyst, Dr. Jason McCarthy. In terms of investor relations, we participated in a number of healthcare conferences in 2021, including the Wainwright 23rd Annual Global Investment Conference and the Emerging Growth Conference, and management continues on an aggressive investor relations strategy forward into 2022. We also joined the Russell Microcap Index in the third quarter of '21, raising the company's corporate profile on helping to develop our investor relations profile. So 2021 was a very active and productive year driven by our success in raising capital in a challenging financial environment for the biopharmaceutical sector. I'd now like to turn the call back over to our CFO, Rob Shawah, to guide you through the highlights of our financial results for the fourth quarter and full year 2021. Rob.
