Thanks, Steve. On June 29, Synthetic Biologics filed an IND for SYN-020 and has received FDA approval proceed with the first clinical trial, the single ascending dose study in normal healthy volunteers. As we enter the clinical stage, it seems like an opportune time to provide some details about the program. Any published data to which I refer will be referenced on our any company website. SYN-020, is a recombinant form of bovine intestinal alkaline phosphatase, which I'll refer to as IAP, produced in flow cells and formulated for oral delivery. In mammals, including humans, IAP is an endogenous enzyme produced by the cells that line the small intestine, and it functions to remove a phosphate group from multiple different substrates. IAP released by these cells is not digested. It travels through the intestine in biologically active form that plays a key role in maintaining gut health through at least three important mechanisms. First, it diminishes gastrointestinal inflammation by detoxifying multiple inflammatory molecules, probably the most important of which is endotoxin. Second, it acts directly on the intestinal wall to tighten the gut barrier to diminish so called leaky gut. Third, it functions to support a healthy bacterial microbiome. Based on these functional activities, we and others have recognized that oral administration of IAP has the potential to treat inflammatory diseases of the GI tract. And this clinical strategy is well supported by multiple animal models, as well as a pilot study in humans with ulcerative colitis. But equally important, by detoxifying intestinal inflammatory mediators, and by preventing them from leaking out into the systemic circulation IAP has the potential to diminish chronic low-grade systemic inflammation, which is believed to exacerbate metabolic syndrome and accelerate the progression of diseases associated with aging. More on this in a minute. At Synthetic Biologics, we've been collaborating with Dr. Richard Holden, Chief of the Division of General and Gastrointestinal Surgery at Massachusetts General Hospital. Dr. Holden has been researching IAP for decades, and is a world leader in exploring its efficacy in animal models of disease. In 2013, he published a seminal paper demonstrating that IAP treatment of mice with metabolic syndrome was remarkably effective in treating this or dramatically reducing both high blood sugar and the associated fatty liver disease. More recently, he showed that long term supplementation with IAP in mice diminished the inflammatory and metabolic changes that occur with normal aging. Amazingly sustained oral administration of IAP substantially prolonged the mouse lifespan. Synthetic Biologics has an exclusive option agreement with Mass General Hospital to license the intellectual property pertaining to the prevention and treatment of metabolic and inflammatory disorders associated with aging. I would encourage you to take a look at Dr. Holden's papers, which encompass a multitude of animal models for other disease indications. I hope I've conveyed the message. So, one of the most exciting aspects of the SYN-020 product candidate is this potential utility for a broad array of clinical indications. You might ask why haven’t other companies already developed an oral IAP therapeutic. The answer would seem to be it is remarkably difficult to manufacture. Most of the studies in the literature have been performed with IAP derived from CAF intestines. CAF IAP costs up to $10,000 a gram, which is prohibitive for an oral therapeutic and public reports with various recombinant platforms have described very poor you, again, insufficient for an oral therapeutic. And at Synthetic Biologics, we've overcome this hurdle. Our unique advantage is that we've been able to generate a high yield production cell line that at commercial scale is anticipated to enable cost effective manufacturing. We've demonstrated that the recombinant SYN-020 is biologically equivalent to CAF derived IAP and it is well tolerated in mouse into our toxicology studies, the dose is up to 50 fold above the anticipated clinical dose. As mentioned previously, we filed an IND that received a study may proceed approval from the FDA. For the initial clinical application, we looked for a NICE indication that could potentially provide an accelerated path to registration. Our current top choice is the enterocolitis associated with radiation therapy for rectal and anal cancers. Since the radiation field for these cancers includes the lower abdomen, patients frequently experienced acute side effects, including diarrhea, nausea, vomiting, and cramping. While these symptoms usually abate, upon completion of the radiation dosing, up to 50% of cancer survivors will go on to develop a long-term complication of intestinal fibrosis, which can be debilitating and has a significant unmet medical need. There's currently no way to present it as well as course. While we will initially focus on the acute toxicities, there is a significant opportunity for SYN-020 to potentially address the long-term complication as well. Finally, in support of this implication, oral administration of IAP was efficacious in two published animal models with radiation exposure, and we verified that SYN-020 was efficacious in our own pilot study in mice. I would be remiss if I didn't mention that we're also exploring the utility of SYN-020 for Celiac disease, which is an autoimmune disease that condemns patients to a lifelong, highly restrictive, gluten free diet. Celiac is particularly intriguing, because when the disease is active, it's associated with low IAP levels, and but barrier leakage, just supplemental SYN-020, which seems to be ideally suited to remedy these abnormalities. To be clear, the disease can be complex with both intestinal and extra intestinal presentations. However a clinical trial design that incorporates that gluten challenge could potentially provide an early readout on SYN-20 utility. We look forward to sharing additional updates on this in the future. To conclude our initial Phase 1 studies will be conducted in normal healthy volunteers. These safety studies will support the subsequent gastrointestinal trials, but more broadly, should also enable the pursuit of other clinical indications. Ultimately, the goal is to leverage low cost manufacturing and the expanse of clinical opportunities offered by SYN-020 addressed metabolic as well as age related disorders. So thanks for your attention. And let me now turn it back to Steven.
