Thanks Steve. At this time, I like to provide a clinical update for our two lead microbial focused [Indiscernible] programs. 2016 proved to be a transformative year clinically for our company highlighted by the announcement of clinically significant Phase 2 trial results for ribaxamase and SYN-010. As a result of this momentum, Synthetic Biologics is uniquely positioned amongst our clinically focused microbiome peers with two late stage unencumbered and potentially best-in-class Phase III Ready Assets targeted at addressing largely unmet medical needs. I’d like to start with an update on ribaxamase our first-in-class oral enzyme designed to degrade certain IV beta-lactam antibiotics excreted into the GI tract to protect and preserve the naturally occurring dead microbiome for the prevention of CDI, AAD and the emergence of anti-microbial resistance. We are very excited about the potential for ribaxamase as a first line of defense against the unintended and damaging effects of antibiotic therapies to the gut microbiome. A healthy, diverse and balanced microbiome is associated with better overall health whereas an imbalanced microbiome also known as dysbiosis may contribute to the diseases ranging from infections in central nervous system disorders to various metabolic illnesses and perhaps even some cancers. The presence of a healthy, robust and well balanced gut microbiome can protect against the threat of infection by blocking colonization, by opportunistic and pathogenic microbes. This is because the diversity of microbes present in a healthy gut microbiome as a system or checks imbalances allowing the ecosystem of microorganisms to remain relatively steady. While species of microorganisms are limited or sharply reduced in the gut, this ecosystem is disrupted and may allow overpopulation by opportunistic, pathotgenic bacteria such as C. difficile. IV antibiotics are administered systemically to fight primary bacterial infections like pneumonia. The body disposes of residual IV antibiotics by carrying them through the liver for transport in the bile. Eventually the body excretes this still functional antibiotics via the large intestine. But this may unintentionally upset the natural balance of microbes in the GI tract by killing off good bacteria. Ribaxamase is designed as a first line of defence against this disruption and is specifically formulated to bypass the stomach avoiding systemic absorption and does not interfere with the ability of IV beta-lactam antibiotics to fight against primary infections. By protecting the patients native gut microbiome ribaxamase prevents the overgrowth of pathogenic organisms responsible for the development of CDI and other pathogenic organisms that may emerge as a result of antibiotic use. Earlier this year, we announced positive topline results from our global Phase 2b randomized placebo controlled proof of concept clinical trial for ribaxamase which consisted of 412 patients. We were very excited to report that ribaxamase achieved its primary endpoint from a statistically significant reduction in the incidence of CDI when compared to placebo. Preliminary topline analysis of the data indicated seven confirmed cases of CDI in the placebo group versus two cases in the ribaxamase treatment group, representing the relative risk reduction of 71.4%. Simply put, patients on a Phase 2b clinical trial who were administered ribaxamase in conjunction with IV ceftriaxone were 71.4% less likely to develop a C. difficile infection compared to patients receiving IV ceftriaxone and placebo. Interestingly, both cases of CDI occurring in the treatment group, occurred in patients who were administered ceftriaxone prior to their first dose of ribaxamase which was permitted under the protocol. It is also interesting to note that the patients newly colonized with C. diff to receive ribaxamase were less likely to progress to CDI than the patients treated with placebo who became newly colonized with C. diff. Both of these findings further reinforced the concept that the prevention of dysbiosis is the key to prevention of CDI. Preliminary results from this trial also demonstrated that while not reaching statistical significance as defined by the protocol secondary endpoint a clear and positive trend in the reduction of antibiotic-associated diarrhea from all causes for the most part to the reduction of CDI was observed in the ribaxasame treatment group as compared to the placebo group. When we initiated the ribaxasame program we believe ribaxasame had the potential to prevent the development and proliferation of anti microbial resistance in the gut microbiome. This thinking was predicated on prior Phase 2 results from a European study. Protecting against disruption of the gut microbiome may prevent environmental conditions in the GI tract that are conducive to the development of antimicrobial resistance. In designing our Phase 2b potentially pivotal study we incorporated exploratory endpoints designed to evaluate ribaxasame’s ability to protect the gut microbiome from colonization by opportunistic and resistant pathogens. One such pathogen is vancomycin-resistant enterococci or VRE. VRE can live in the human intestines and remain passive, kept in check by a healthy and robust microbial community, however if present in a Dysbiotic gut microbiome, VRE can aggressively proliferate in develop into a serious infection which may not be treatable by available antibiotic therapies. Preliminary analysis of our Phase 2b data demonstrate a statistically significant reduction, a P value of 0.0002 in new colonization by VRE for patients receiving ribaxamase as compared to placebo. A particular relevance as it relates to these data is to remember that patients enrolled in this trial were not treated with vancomycin and they came at the development of new colonization by VRE and other resistant pathogenic micro organisms is not limited to antibiotic mediation of the guy microbiome but instead may force and transfer the month’s patients in hospital settings. We are currently in the process of analyzing additional data from these exploratory endpoints designed to evaluate ribaxasame’s ability to protect the guy microbiome from opportunistic bacteria such as VRE. This includes analysis through funding awards to synthetic biologics from the centers for disease control and prevention the CDC to support research from our Phase 2b trial. Following the completion of analysis from these antibiotic microbial resistance focus exploratory endpoints we plan to meet with the CDC to share our findings and subsequently anticipate requesting end of Phase 2 meeting with the FDA later this year. Our goal is to work with the FDA to determine the appropriate regulatory pathway for Phase 3 development of ribaxamase with input from the CDC. We expect to initiate our first pivotal trial for ribaxamase during the first half of next year. The results from our Phase 2b study are consistent with the ribaxamase’s mechanism of action and provide a compelling demonstration of the potential of ribaxamase to help address the serious health and economic impacts associated with CDI, AAD and AMR resulting from antibiotic mediated dysbiosis of the guy microbiome. Ribaxamase represents a new, disruptive and simple approach to its rolling complex problem and may directly lead to more effective and efficient use of antibiotics. We seldom talk about our additional early stage programs which we view as [Indiscernible] extensions of ribaxamase. Utilizing our expertise and knowledge in the microbiome arena we are currently developing pre-clinical stage programs which harnest the same formulation expertise currently utilised for ribaxamase. The first is known as SYN-006. It is an enzyme comparable to ribaxamase and is designed to degrade residual IV carbapenem antibiotics in a similar fashion. Carbapenems are exceptional powerful antibiotics which are typically used as a drug of last resort. As noted earlier, antimicrobial resistance and the emergence of superbugs is making this class of compounds less effective. Synthetic biologics is developing a program to remediate this situation. In addition, our second extension of ribaxamase is called SYN-007. SYN-007 is a special formulation of ribaxamase designed to be co-administered with oral beta-lactam antibiotics such as [Indiscernible]. Again, the quest is to reduce the destruction of the microbiome and minimize the emergence of superbugs. The market for oral beta-lactam antibiotics is significantly larger than the market for IV beta-lactam antibiotics which is also quite large. We view ribaxamase in a sister compounds and formulations as a franchise not a single compound with the potential to have a significant lasting benefit for the way we administer antibiotics for many years to come. We view this program as a cradle to grave concepts were and we will continually be able to protect the gut microbiome from the time you're born until the time you die, thus preventing many diseases downstream. I like to switch gears SYN-010 now, our program designed to target and treat an underlying cause of irritable bowel syndrome with constipation. Currently marketing development stage therapies for IBS-C are designed as Me-Too or Me-Better drugs. They have been shown to treat the symptom of constipation associated with IBS-C but do little to address the abdominal pain and bloating. These therapies provide temporary relief to a long-term and often lifestyle altering and recurrent problem, and usually have serious side effects most commonly diary. In previously reported studies methane production in the gut was shown to be the primary causative factor of the symptoms associated with IBS-C. If follows then that by reducing methane production in the gut we can treat the cause of the symptoms associated with IBS-C potentially providing sustainable relief to the millions of people suffering from this disease around the world. This is our goal and our microbiome focus solution is what makes Synthetic Biologics, SYN-010 an outlier in the current landscape of IBS-C focused therapies. It is a game changer. Our gut microbiomes are comprised of thousands of species which represent trillions of cells existing symbiotically within the G.I. tract. One species in particular M. smithii, he is responsible for the vast majority of methane production in the gut. In previous Phase 2 trials we show that by interrupting the methane cycle of this specific microbial are proprietary formulation of SYN-010 we influence positive therapeutic outcomes in IBS-C patients with minimal impact to their naturally occurring gut microbiome with almost a zero occurrence of diarrhea. During the second quarter 2016 we announced positive results from these Phase II clinical trials which demonstrate that patients in the SYN-010 treatment groups experienced clinically significant improvements in bowel movements, abdominal pain and bloating compared to the placebo group. Following this announcement we held collaborative discussions with the FDA to determine the optimal regulatory pathway to advance SYN-010 into Phase 3 development. During the fourth quarter of 2016 we announced that Phase 2b/3 adaptive pivotal trial designed to further evaluate the efficacy and safety of SYN-010. Key components of our first pivotal trial for SYN-010 include a 12-week multi-center double-blinded placebo-controlled adaptive design, a study population of approximately 840 adult subjects, evaluation of efficacy and safety of two doses of SYN-010 21 mgs and 42 mgs compared to placebo, conducted approximately 150 clinical sites in North America, study subjects will be randomized in a 1:1:1 ratio receiving either 21 mgs, 42 mgs or placebo. Enrolment is open to all IBS-C patients. Breath methane will be measured at baseline to ensure comparable ratio high to low breath methane IBS-C patients at each treatment arm. An interim futility analysis may also be conducted with approximately 50% of patients in each dosing arm have completed treatment. Clinical Research conducted in Dr. Mark Pimentel's lab at Cedars-Sinai Medical Center suggest that M. smithii is a common inhabitant in most of our gut microbiomes and is not exclusive to IBS-C patients. You may recall Dr. Pimentel spent years researching bowel syndrome and was responsible for discovering the billion dollar plus drug rifaximin commercially known as Xifaxan for IBS diarrhea. This scientific and clinical insight enable him to identify M. smithii as a causative factor of IBS-C. Since an individual's microbial balances play a key role in determining the level of methane production in the gut there is no ubiquitous standard for what constitutes healthy or unhealthy methane production, in other words a one-size-fits-all approach to measuring therapeutic outcomes based on methane production alone would be inappropriate. We believe SYN-010 may provide a therapeutic benefit for all IBS-C patients. Unlike previous clinical trials for SYN-010 which measure breath methane is criteria for enrolment, our Phase 2b/3 clinical trial will be open to all adult IBS-C patients, breath-methane will be measured at baseline to ensure comparable ratio of methane IBS-C patients in each arm. Consistent with FDA written guidance, the primary objective for the studies to determine the efficacy of SYN-010 measured as an improvement from baseline in the percentage of overall weekly responders during the 12-week treatment for SYN-010 21 milligrams and 42 milligram daily doses compared to placebo. Secondary efficacy endpoints for both those strengths of SYN-010 will measure changes from baseline in abdominal pain, bloating, bowel movement frequency and stool consistency. With a clear path forward for SYN-010’s clinical development we are one step closer to achieving the goal of providing millions by IBS-C patients with a novel potentially best-in-class therapy that directly targets a root cause of IBS-C. We have reflected upon the importance of initiating our Phase 2b/3 pivotal study for SYN-010 with full confidence that we have the clinical and financial infrastructure necessary for its full, timely and successful completion thus once these components are solidified we intend to start the study later this year. To that end, we continue to evaluate and engage in ongoing discussions with several potential U.S.-based pharmaceutical partners as well as interested parties in Europe, China and Japan. In 2017 we’ll look to build upon the clinical successes of the last year as we continue to more primitive discovery early-stage Platform Company to a late-stage development company with an eye towards commercialization. At this time, I'll turn back over to Vincent.
