Thanks, Rob. Good morning, everyone. And thanks for joining us on this conference call to review our financial results. During today's call, we will review our financial results for the quarter-ended June 30 and also cover some key corporate highlights. And then we'd be pleased to take any questions. In the second quarter, we continue to enroll more patients in the Phase 2b clinical trial of ibezapolstat, our lead antibiotic candidate for the treatment of patients with C. difficile Infection, or CDI. The Phase 2b clinical trial is a 64 patient randomized one-to-one non-inferiority double blind trial of oral ibezapolstat compared to oral vancomycin, a standard of care for the treatment of CDI. The primary endpoint of the Phase 2b clinical trial is clinical cure at the end of treatment, and the secondary endpoint is sustained clinical cure measured at day 30th follow up visit. Since this is a double-blind trial, results won't be known until the end of the trial. However, operationally the trial is proceeding as expected with no safety signals recorded to-date. The protocol includes an exploratory endpoint comparing the impact on the microbiome between ibezapolstat and the oral vancomycin, and the event non-inferiority of ibezapolstat to vancomycin is demonstrated. Further analysis will be conducted to test for superiority. Additionally, due to slower than expected enrollment, we expanded the number of clinical trial sites participating in the Phase 2b trial, from the initial eight U.S. trial sites to up to 30 trial sites. Currently, there are 16 trial sites open for enrollment, with an additional eight trial sites currently onboarding at this time. We remain particularly excited about the dual impact of using ibezapolstat to treat acute CDI, while appropriately managing the long-term care of each patient's microbiome, which we believe is exceptional for antibiotic therapy. Other key highlights from the second quarter of 2022, or in some cases shortly thereafter, include the following. First, we've completed certain portions of our laboratory study at the University of Houston, comparing the killing effect of ibezapolstat, vancomycin, fidaxomicin and metronidazole using both in-vitro and ex-vivo analyses. Certain results were presented on our behalf by Dr. Eugenie Bassere, Professor at the University of Houston College of Pharmacy at Anaerobe 2022, The Anaerobe Society of America Annual Scientific Conference. The conclusion from this study, from the data presented to-date, analyzed to-date, is that ibezapolstat demonstrated favorable killing kinetics compared to currently marketed antibiotics to treat C. difficile Infection at standard and high concentrations, supporting continued development of a potential first-in-class antibiotic to treat C. difficile Infection. Secondly, in terms of highlights, ibezapolstat presentations have also been accepted at three upcoming prominent scientific conferences later this year, including the Antimicrobial Resistance Conference in September, ID Week in October, and the C. Diff Foundation Conference in November. Third, our scientific collaboration with Leiden University Medical Center continues to support our preclinical development program, to further study the mechanism of action of pol IIIC inhibitors, in a consortium partnership with our company. This innovative research project under a $500,000 grant to Leiden University Medical Center with Acurx as its consortium partner is studying three-dimensional structures of DNA polymerases, and their binding interactions with Acurx inhibitors. The antimycobacterial molecular target of Acurx's pipeline of novel DNA pol IIIC has been clinically validated by ibezapolstat's recent completion of its Phase 2a trial in C. diff infection. The research outcome at Leiden University is intended to accelerate lead product candidate selection for our ACX-375 program, our second drug for systemic treatment against multi-drug resistant Gram-positive bacteria, where no new classes of antibiotics -- where new classes of antibiotics are urgently needed. This project was initiated by Leiden University in September '21, and emerging data are expected to facilitate the 375 program development. Fourth, in July 2022, we launched an innovative patient enrollment acceleration program to optimize patient enrollment in our ongoing 2b trial of ibezapolstat in patients with C diff. Our newly instituted referring physician program involves principal investigators and study coordinators of our clinical trial sites, reaching into potential referring physicians within an appropriate -- an approximate 25-mile radius from our clinical trial sites. In each case, we've identified potential referring physicians as high prescribing physicians of the most commonly used antibiotics for the treatment of C Diff over in recent 12-month period from IMS data. According to the physician prescribing data available to us from an industry standard source, identified referring physicians in the aggregate just 14 -- the first 14 of our currently activated trial sites treated a total of over 30,000 patients in a recent 12-month period, suggesting that a substantial number of subjects could potentially be available for referral to one of the 14 clinical trial sites if the patient is qualified. The first tranche of this program has been activated with four of our clinical trial sites, and is planned to be followed up later this year with a second tranche as we expand our participating sites from 16 up to 30. We believe the referring physician program, which has a number of other supportive elements will enhance the rate of enrollment, potentially mitigating or partially mitigating the countervailing enrollment disruption caused by the COVID-19 pandemic. Additionally, to reiterate, in July 2022, we increased the target number of clinical trial sites participating in our Phase 2b trial from a targeted 24 sites from last quarter up to 30 sites now, with 16 sites active and eight more onboarding. Our scientific team will continue to target six additional trial sites to participate in the 2b clinical trial. Finally, in July '22, the company raised an additional $4.225 million of gross proceeds by consummating a registered direct offering issuing an aggregate of 1,290,000 shares of common stock, which included about 130,000 pre-funded warrants to purchase shares of our common stock to one institutional investor at a purchase price of $3.25 per share, which represents for common shares at $0.001 share exercise price, for the pre-funded warrants, and a price of $3.80 per share for the company's executives that invested in the offering, three of us in particular. The company has also issued to each investor a Series A unregistered warrants to purchase 1,290,000 shares of our common stock and a Series B warrant to purchase another 1,290,000 shares of our common stock. The B warrant has a one and a half year expiry and has no cash flows exercise unless not registered with the SEC, which basically means we'll get another $4.2 million in the door, assuming success with the Phase 2b trial. Now, back to our CFO, Rob Shawah, to guide you through the highlights about some interesting stuffs for the second quarter of '22. Rob?
