Thanks, Evan. I'd like to begin with a discussion of our MS oral candidate, Trimesta, which is currently in a Phase II trial. Trimesta is being evaluated in a randomized, double-blind, placebo-controlled, 15-center Phase II clinical trial for the treatment of relapsing-remitting MS in women. Patient enrollment is complete, and per FDA guidance for MS trials, the patients are dosed and monitored over a 2-year period of time. The primary endpoint for this trial is relapse rate at 2 years. In June, we hosted an investor day to promote MS awareness and the market potential of our unique oral estriol candidate, Trimesta. We were pleased to welcome Dr. Rhonda Voskuhl as the keynote speaker. Dr. Voskuhl holds the titles of Professor, Department of Neurology at the Jack H. Skirball Chair in MS Research and is a Director of the MS Program at the UCLA School of Medicine. And important to us, she is the lead investigator of the Trimesta clinical trials. During the event, Dr. Voskuhl led an in-depth discussion about the MS space and the role of estriol in the treatment of multiple sclerosis. In April 2013, we announced that our U.S. patent was issued to the regents of the University of California, which includes claims to the use of our drug candidate, Trimesta, in combination with glatiramer acetate injection, more commonly known as Copaxone, to our wholly owned subsidiary. We hold the exclusive worldwide license to this patent for multiple sclerosis and other autoimmune diseases covering the uses of Trimesta. In the ongoing Phase II clinical trial, our Trimesta is administered in combination with the Teva product, Copaxone. Copaxone is the #1 selling drug for MS with approximately $4.2 billion in annual sales. It is currently marketed exclusively by Teva Pharmaceuticals Industries, and Copaxone is expected to face fierce generic competition as certain patent terms begin to expire later next year. So to wrap up our MS discussion, in about 5 months, the patients being evaluated with our candidate, Trimesta, will finish their visits, and the relapsing-remitting MS Phase II clinical trial should be completed. We then expect top line results to be reported thereafter. This is an important milestone for us, and we look forward to announcing the Trimesta data, which is intended to provide both inflammatory and potentially neuroprotective benefits for MS patients. Now I'd like to turn to our pipeline of anti-infective product candidates. Our lead infectious disease candidate is SYN-004, a point-of-care prevention for C. difficile or C. diff infections. Some of you might be aware that a recent M&A deal that consisted of Cubist acquiring Optimer and their product, Dificid, with a potential value of $801 million. It was approved May in 2011. Dificid, the drug itself, was approved in May 2011 as the first new antibiotic approved in 25 years for the treatment of infections by the bacteria, Clostridium difficile. SYN-004 is an entirely different and novel treatment paradigm, which I'll outline at this point in time. So what is C. difficile? C. diff is a nasty hospital-acquired bacterium. You don't want it, and that's why we're so excited about developing an oral enzyme prophylactic to prevent -- I repeat, to prevent C. diff, not treat C. diff. We believe this will be a breakthrough candidate within a market where no approved product currently exists. If you haven't heard about C. diff in the news or from a friend or family member, let me take a moment to give you an example. You're hospitalized and being treated for a primary infection, for instance, pneumonia, with an IV beta-lactam antibiotic. As the antibiotic is working to fight your pneumonia, it may be excreted into the GI tract, where it can upset the natural balance of the microbiome allowing for the overgrowth of C. diff, which causes diarrhea, colitis and may result in death. What we intend for SYN-004 is for the patient to take our oral enzyme at the same time as they are administer the IV beta-lactam antibiotic, and then for SYN-004 to degrade certain antibiotics in the GI tract, protecting the native microflora in the gut, and thus preventing the opportunity for C. diff infections to flourish. Our second-generation compound, SYN-004, is designed to address a broader population than its predecessor, which successfully completed a proof-of-concept Phase II study in Europe. Data from the Phase I and Phase II studies of over 200 subjects treated with the first-generation candidate demonstrated exceptional safety, tolerability and preservation of the normal GI microflora. When co-administered with certain penicillins, our second-generation enzyme, SYN-004, is designed to expand the spectrum of beta-lactam antibiotics to include both the penicillins as well as the cephalosporins. Market research tells us that in 2012, 24 million patients were administered IV antibiotics in the U.S. alone, of which over 13 million of those patients were treated with IV beta-lactam antibiotics that may be degraded by our SYN-004 product candidate. That is one big market for this particular product. So where are we with this program? What are we going to -- what are we doing to move toward our goal of developing a prophylactic to prevent the devastating effects of C. diff infections? In July, we initiated the SYN-004 manufacturing process. The first phase of this process included the evaluation of beta-lactamase protein expression, and we are pleased to have Fujifilm Diosynth Biotechnologies in the U.K. conducting these studies by using its pAVEway platform. This is an important first step in the SYN-004 manufacturing process. Once the production cell line evaluation is completed and we select the optimal expression clone, we intend to proceed rapidly with the manufacturing of preclinical material for animal studies and cGMP manufacturing of SYN-004 for clinical studies. We expect to initiate the cGMP manufacturing of SYN-004 in Q3 of this year. And with completion of that, we should be able to commence toxicology bridging studies followed by the start of clinical trials in 2014. We are on target to meet those milestones. Next, I'd like to turn to the development of our monoclonal antibodies to treat infectious diseases and our ongoing collaboration with Intrexon. Most of you are aware that Intrexon just did an IPO, which went out exceptionally well. But in all honesty, I don't really consider this an IPO. I consider this birth of a new set of industries, a brand-new paradigm on not only having developed drugs, which is our space, but all sorts of better technologies from biofuels to aquaculture. I'm proud to be part of Synthetic Biologics as we are one of the very first collaborations with Intrexon. And I look forward to moving our products forward together with the Intrexon team. In developing the interlinking, cutting-edge cellular technologies for a broad range of applications as Intrexon does, an antibody discovery platform has been created that is powered to yield novel molecular entities intended to treat diseases for which current therapies are inadequate. Our collaboration with Intrexon is a prime example of how 2 innovative companies can work together to pursue significant medical advances. That being said, we are making excellent progress in our collaboration with Intrexon for antibody programs, which currently covers treatment candidates for 2 different diseases, Pertussis and Acinetobacter. The first mAb therapy, the first monoclonal antibody therapy, which is intended to neutralize the pertussis toxin, will undergo initial preclinical testing in the third quarter of this year and is expected to enter IND-enabling studies before year end. Pertussis or whooping cough is responsible for 300,000 deaths annually worldwide -- these are mostly infants, and afflicts about 41,000 people each year in the United States. And that incidence is increasing. The second monoclonal antibody collaboration with Intrexon is currently in the discovery stage for the treatment of Acinetobacter baumannii infections. This is a nasty, gram-negative bug. The urgency to develop a treatment against this deadly pathogen remains very high. Mortality rates as high as 43% have been reported, and incidence of the disease is reportedly increasing, especially among wounded military personnel in field medical settings and natural disaster victims in the emergency trauma units. Our C. diff program and Acinetobacter candidates may qualify for expected review programs at the FDA for the treatment of serious conditions with unmet medical needs, such as those addressed by the GAIN Act. These expedited programs established by the FDA not only point the way to -- the urgency for new medications for devastating diseases but also potentially shorten the time significantly to market. Recently, we strengthened our core competencies in anti-infectives with the appointment of industry veteran Lewis Barrett to the position of Senior Vice President, Commercial Strategy. Mr. Barrett was formerly Assistant Vice President, Established Products at Pfizer and VP, Global Business Manager, Infectious Diseases at Wyeth for many, many years. Lew was instrumental in building the brand and led global commercialization efforts for Wyeth's in-line IV antibiotic, Zosyn, and the second antibiotic to achieve $1 billion plus in revenue and managed the U.S. launch of Wyeth's broad-spectrum IV antibiotic, Tygacil. We are pleased to welcome Lew to the Synthetic Biologics team. We continue to be in discussions with Intrexon on our third program. And we are -- at this point in time, both teams are looking at a variety of projects to decide which one we're going to definitively agree upon and move that product into the discovery line and forward. We feel that our development efforts, combined with our engagement with the investment community, have strengthened our position as we begin to penetrate the untapped infectious disease market. It's an exciting time for our company as we move forward. Again, we remain on track to report top line results for Trimesta as the relapsing-remitting MS trial wraps up in about 5 months. We are pleased with the continued progress we are making to execute our strategy to address the increasing need for therapies that prevent and treat infectious diseases through our portfolio of target-specific biologics. We believe our programs represent a unique and strong value proposition. We are working to execute our plans and realize the full potential of the pipeline we have built and ultimately drive significant patient and shareholder value. At this point, I'd like to turn the discussion over to Kris Maly.
