Thank you, Rob. Good morning, everyone and thanks for joining us on this conference call to review our financial results. During today's call we’ll review our financial results for the first quarter ended March 31 and also cover some key corporate highlights and then we'd be pleased to take any questions. In the first quarter, more patients were enrolled in the Phase 2b clinical trial of ibezapolstat, our leading antibiotic candidate for the treatment of patients with C. difficile Infection or CDI. The Phase 2b clinical trial is a 64 patient randomized 1-to-1, non-inferiority, double-blind trial of oral ibezapolstat, compared to oral vancomycin, a standard of care to treat CDI. The primary endpoint of the Phase 2b trial is clinical cure of C. difficile Infection at the end of treatment measured on day 12 and a secondary endpoint as sustained clinical cure measured at day 38 follow-up visits. Since this is a double-blind trial, results will not be known until the end of the trial. However, operationally the trial is proceeding as expected [Technical Difficulty] these signals reported today. Also included in the protocol is an exploratory endpoint comparing the impact on the microbiome between ibezapolstat and vancomycin. In the event non-inferiority of ibezapolstat and vancomycin is demonstrated in the Phase 2b trial, further analysis will be conducted to test for superiority. Additionally, based on the strength of our previously reported Phase 2a results, which demonstrated 100% clinical cure in patients after a 10-day treatment for CDI with no recurrence of infection at the day 38 eight follow visit, we've added a novel exploratory endpoint in the Phase 2b trial of extended clinical cure or ECC for study visits at day 56 and day 84 after the end of treatment for a selected group of subjects to evaluate the longer-term effect of ibezapolstat on the microbiome and on disease recurrence. To our knowledge, no other comparable long-term data such as this has been conducted or reported with currently used antibiotics to treat C. difficile Infection to date. The Phase 2b clinical trial will include up to 24 U.S. sites with enrollment expected to be completed late in the second half of this year. We remain particularly excited about the dual impact of using ibezapolstat to treat the acute infection of CDI, while appropriately managing the long-term care of each patient's microbiome, which we believe is exceptional for antibiotic therapy. We reiterate that with the closing of our IPO in June 2021, we have more than enough cash to complete the ibezapolstat’s Phase 2b trial and related R&D matters, as well as to allocate resource to advanced development of ACX-375C, our second DNA pol IIIC inhibitor, currently in lead optimization stage of preclinical development for the treatment of other gram-positive bacterial infections, including MRSA. Other key highlights from the first quarter of 2022 include the following. Our laboratory study at the University of Houston comparing microbiome changes of ibezapolstat to vancomycin, fidaxomicin, and metronidazole using both in vitro and ex vivo analysis is ongoing. The objective of this study is to expand our very positive Phase 1 and Phase 2a microbiome data using an in vitro gut model that mimics human gastrointestinal physiology. Shortly after the end of the first quarter, we submitted a grant application to the NIH, National Institute of Allergy and Infectious Disease for approximately $23 million of non-diluted funding to support the ongoing development of ACX-375C. If approved, these funds would cover the costs of ACX-375C all the way through Phase 1 clinical trials for our lead clinical indication, including reimbursement to the company for certain G&A costs. The company anticipates a final decision on this funding opportunity in the second half of this year and we will continue to monitor other potential funding opportunities and we do anticipate submitting at least one more application in this regard for external funding this year. We're continuing our scientific collaboration with Leiden University Medical Center to further study the mechanism-of-action of pol IIIC inhibitors and a consortium of partnership with our company. The innovative research project under a $500 million grant to the Leiden University Medical Center with Acurx as its consortium partner is studying three dimensional structures of DNA polymerases and they're binding interaction with Acurx inhibitors. The antibacterial molecular target of Acurx’ pipeline of Novel DNA pol IIIC inhibitors has been clinically validated by ibezapolstat’s recent completion of its Phase 2a trial in CDI. The research outcome at Leiden University Medical Center is intended to accelerate lead product candidate selection for our ACX-375C program for systemic treatment against multi-drug resistant Gram-positive bacteria, where new classes of antibiotics are urgently needed. This project was initiated by Leiden University Medical Center in September 2021 and emerging data are expected to facilitate the 375 program. Now, I'll turn the call back to our CFO, Rob Shawah to guide you to the highlights of our financial results for the first quarter of 2022. Rob?
