On November 28, 2012, a closing was held for the transaction previously announced on November 12, 2012 between Synthetic Biologics, Inc. (the “Company”) and Prev ABR LLC (“Prev”). The Company issued 625,000 shares of Company common stock (the “Shares”) in partial consideration for the acquisition of theC.diff program assets of Prev, including pre-Investigational New Drug (IND) package, Phase I and Phase II clinical data, manufacturing process data and all issued and pending U.S. and international patents. The offer and issuance of the Shares have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), and therefore may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements. For this issuance, the Company is relying on the exemption from federal registration under Section 4(2) of the Securities Act, based on the Company’s belief that the offer and sale of the Shares does not involve a public offering as all of the members of Prev have represented that they are “accredited investors” as defined under Section 501 promulgated under the Securities Act and no general solicitation has been involved in the offering.
On December 3, 2012, the Company issued the press release attached hereto as Exhibit 99.1 regarding the closing described herein.

On November 28, 2012, the Company completed the closing of its Asset Purchase Agreement with Prev, which was previously announced in the Company’s press release on November 12, 2012.

Synthetic Biologics Closes Deal for Acquisition ofC. difficile Infectious Disease Program
For Immediate Release
Rockville, MD, December 3, 2012 – Synthetic Biologics, Inc. (NYSE MKT: SYN), a developer of synthetic biologics and innovative medicines for serious infections and diseases, announced today that the Company closed the previously announced deal with Prev AbR LLC (Prev) and acquired a series of β-lactamase compounds (P1A, P2A and P3A) and related assets targeting the prevention ofClostridium difficile(C. diff)infection. Utilizing the newly acquired biologic compounds, Synthetic Biologics intends to develop a proprietary oral β-lactamase enzyme product candidate, SYN-004. When co-administered with certain β-lactam antibiotics, it is expected that SYN-004 can degrade the antibiotic and preserve the balance of the patient’s gastrointestinal (GI) microflora, thus preventing opportunisticC. diff infection (CDI). β-lactam antibiotics are a mainstay in hospital infection management and include both penicillins and cephalosporins. In 2011, an estimated 8.7 million Americans were administered intravenous β-lactam antibiotics.[1]
“Our Company’s primary focus is on the development of biologics to prevent and treat multidrug-resistant infectious diseases, and we are pleased to add theC. diff program to our pipeline. We believe we are at the forefront of developing a prophylactic to prevent the devastating effects ofC. diff infection, for which there is currently no vaccine or other approved preventive therapy,” stated Jeffrey Riley, Chief Executive Officer of Synthetic Biologics. “With regulatory discussions previously initiated by Prev, we intend to continue to work with the FDA to design a regulatory pathway for a new product candidate and to advance to clinical trials as soon as possible.”
C. diff is the leading cause of hospital acquired infections in which the toxins produced by the bacteria result inC. diff-associated diarrhea (CDAD), and in the most serious cases, erosion of the GI tract that can lead to death. In 2009, aggregate costs associated with CDI-related stays in the hospital were $8.2 billion in the U.S.[2]

This release includes forward-looking statements on Synthetic Biologics’ current expectations and projections about future events. In some cases forward-looking statements can be identified by terminology such as "may," "should," "potential," "continue," "expects," "anticipates," "intends," "plans," "believes," "estimates," and similar expressions. These statements are based upon current beliefs, expectations and assumptions and are subject to a number of risks and uncertainties, many of which are difficult to predict and include statements regarding our intention to develop and commercialize a proprietary oral β-lactase enzyme product candidate using the acquired assets that will have the desired results, our intention to commence clinical trials and the expected size of the market for C. diff therapeutics. The forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from those set forth or implied by any forward-looking statements. Important factors that could cause actual results to differ materially from those reflected in Synthetic Biologics’ forward-looking statements include, among others, our inability to timely commence or complete the clinical trials consistent with our current expectations and our inability to successfully develop, receive regulatory approvals for or to commercialize a new product candidate to prevent C. diff infection and other factors described in Synthetic Biologics’ report on Form 10-K/A for the year ended December 31, 2011 and any other filings with the SEC. The information in this release is provided only as of the date of this release, and Synthetic Biologics undertakes no obligation to update any forward-looking statements contained in this release on account of new information, future events, or otherwise, except as required by law.
