Thanks Steve. During the third quarter we remain keenly focused on the advancement of our two clinical assets. To that end Synthetic Biologics remains uniquely positioned amongst our biotech peers with two late-stage unencumbered and potentially best-in-class Phase 3 ready assets targeted at addressing largely unmet medical needs. Our SYN-10 program remains an important component of our microbiome focused clinical portfolio, which we believe will contribute to the growth of our company and provide long-term value to our shareholders. If you recall, SYN-10 is our proprietary modified-release formulation of lovastatin lactone that is intended to reduce methane production by certain microorganisms in the gut, while minimizing disruption to the microbiome to treat the underlying cause of irritable bowel syndrome with constipation. As noted above, SYN-10 remains uniquely positioned against other development stage and currently marketed therapies for IBS-C which are designed solely with the intent of increasing GI motility. Such therapies have been shown to have the unpleasant side effect of shifting patients who suffer from constipation to diarrhea. Data from previously reported Phase 2 studies of SYN-10 demonstrated that in addition to increasing the frequency of complete spontaneous bowl movements SYN-10 also significantly improved abdominal pain and bloating compared to placebo. With the foundation of our Phase 2b/3 pivotal study in place, we continue to work on solidifying its infrastructure with a focus on identifying, evaluating and delivering opportunities to move this program forward in a manner consistent with the best interest of our shareholders. During the third quarter, we continued to evaluate such opportunities while engaging in discussions with potential pharmaceutical partners to move this program into the next phase of its development. We intend to initiate this trial only at a time when the requisite components of its clinical and financial infrastructure are in place to ensure its full timely and successful completion. Switching gears now to SYN-004 or ribaxamase, which is our breakthrough therapy designated program designed to be first line of defense against antibiotic mediated dysbiosis. The presence of a healthy robust and well balanced gut microbiome acts as a system of checks and balances to protect against a threat of infection by blocking the overgrowth of opportunistic microbes. The use of intravenous beta-lactam antibiotics including cephalosporins, is an important risk factor for the development of such overgrowth, which may led to gastrointestinal infections like Clostridium difficile and importantly the emergence and proliferation of resistant genes. Ribaxamase is engineered to protect and preserve the naturally occurring gut microbiome from antibiotic mediated dysbiosis. Its unique mechanism of action has been shown to be a great residual IV beta-lactam antibiotics after systemic absorption and before they affect the naturally occurring flora of the GI tract. This is intended to prevent the overgrowth of pathogenic organisms including the onset of CDI and the emergence of anti-microbial resistance. In our successful Phase 2b 412 patient proof of concept clinical trial, ribaxamase achieved its primary endpoint of significantly reducing the risk of developing CDI in patients by 71.4% compared to placebo. Additional data demonstrate that when compared to placebo, ribaxamase significantly reduced the incidence of new colonization by vancomycin-resistant enterococci or VRE, protected and preserve the naturally occurring composition of native gut microbes and prevented significant changes for the presence of certain anti-microbial resistant genes in the gut resistome of treated patients. We have taken great strides since the initiation of our ribaxamase program a few short years ago. Ribaxamase and its extension programs SYN-006 and SYN-007 have the potential to positively alter the treatment paradigm for antibiotic therapy by limiting the gut microbiomes inadvertent exposure to IV beta-lactam antibiotics. Ribaxamase has the potential to not only prevent the onset of primary CDI, but also prolong the efficacy of existing antibiotics in a time of ever growing anti-microbial resistance. Ribaxamase has the unique distinction as the first ever development stage drug candidate to receive breakthrough therapy designation for the prevention of CDI. This designation is indicative of ribaxamase’s unique and novel approach to CDI and its potential to prevent the more than 500,000 cases of CDI which result in approximately 29,000 CDI related deaths each year in the United States. Breakthrough therapy designation additionally allows for Synthetic Biologics to maintain ongoing and less formal discussions with the FDA as we continue to develop a plan for ribaxamase's late stage clinical development. During the third quarter, we met with the FDA for an initial Type B meeting. The purpose of this initial meeting was to broadly discuss the overarching high level drug development plan and pathway towards marking approval for ribaxamase. Following a review of the data from our Phase 2b proof of concept cycle study, we broadly discussed late stage development opportunities and reviewed timelines for ribaxamase’s clinical advancement. While this initial meeting was productive in nature, we expect to continue to work collaboratively with the FDA in the coming months to ensure the development of a suitable Phase 3 clinical trial protocol and statistical analysis planned for ribaxamase’s clinical development. Given the nature of ribaxamase’s unique mechanism of action as a preventative approach to CDI, we want to ensure we are diligent and thoughtful in the development of a clinical trial protocol that provides the optimal pathway and opportunity for a successful and timely completion. We intend to maintain an ongoing dialog with the agency as we continue to solidify the requisite facets of our Phase 3 development plan, including clinical trial design, cGMP manufacturing and CMC considerations. Looking ahead, we anticipate submitting the request for an additional meeting with the FDA during the first quarter of 2018 to solidify the details and components of the late stage drug development plan and regulatory pathway for ribaxamase. We are pleased with the FDA’s recognition of ribaxamase’s potential to fill a dire need and the current void of an approved intervention to prevent this often debilitating and life altering disease. We look forward to sharing additional details of our late stage clinical development plan for ribaxamase as the details become available and as required. We continue to position our novel portfolio of late stage micro-biome focused assets for Phase 3 development with an eye on commercialization. During the third quarter, we strengthened our balance sheet with the successful completion of a privately placed stock purchase transaction for the sale of redeemable convertible stock to an affiliate of MSD Partners for aggregate gross proceeds of $12 million. We intend to use the proceeds from this transaction in support of our ongoing efforts to advance ribaxamase towards Phase 3 clinical trials as well as for general corporate purposes. The closing of this transaction provides the company with an extended runway as we continue to maintain a lean burn rate focused on cash preservation in support of our two clinical programs. Moving forward, our goal remains unchanged, to create long term value for our stakeholders, including our shareholders and the millions of patients who stand to benefit from our innovative approach to micro-biome focused research and clinical development. At this time, I'll turn it back over to Vincent. Vincent?
