ContraFect Corporation Completes Successful Pre-IND Meeting With FDA

YONKERS, NY--(Marketwire - Dec 14, 2011) - ContraFect Corporation, the company that is pioneering the use of recombinant proteins for the treatment of drug-resistant bacteria, completed a face-to-face pre-IND (Investigational New Drug) meeting with the FDA on December 9, 2011 to discuss the development plans for CF-301, a biologic antimicrobial therapy for acute bacterial skin and skin structure infections. CF-301 is a first-in-class investigational drug with potential to have a major role in the treatment of infections caused by MRSA (drug-resistant staphylococcus) and streptococcus. The FDA addressed the Company's questions and provided guidance on the requirements to file an IND to initiate clinical trials. The IND is expected to be submitted mid-2012.

"The completion of our pre-IND meeting with the FDA is a milestone for ContraFect," remarked ContraFect CEO and Chairman Dr. Robert Nowinski. "We now have confirmation that we are on the right path and are preparing our IND package in manner that will be acceptable to the FDA. We remain on target to initiate our first-in-human Phase I clinical trial in Q3 2012."

About CF-301:

CF-301 is an investigational first-in-class therapy for the treatment of infections caused by staphylococcus and streptococcus. CF-301 is a bacteriophage lysin that acts immediately upon contact with the bacterium, causing a pore to form in the cell wall and resulting in lysis (death) of the target bacteria. The unique mechanism of action of CF-301 makes it active against all forms of staphylococcus and streptococcus infections, regardless of existing resistance to current antibiotics, including methicillin (MRSA) and vancomycin (VISA and VRSA) resistant strains.

About ContraFect:

ContraFect Corporation is a biotechnology company pioneering the use of Lysins and Monoclonal Antibodies to treat life-threatening infectious diseases. ContraFect's initial products include agents to treat diseases such as MRSA (drug-resistant staphylococcus bacteria), other serious bacterial infections, and influenza.

Our scientific approach is based on the following principles:

• Monoclonal Antibodies for the treatment of life-threatening bacterial and viral diseases
• Lysins for the treatment of drug-resistant gram positive bacteria, such as staphylococcus (MRSA), streptococcus and intestinal infections
• Transition from conventional monotherapy to a combinatorial approach using multi-therapy antibody and Lysin treatments
• The growing challenge of drug-resistance and therapy escape mechanisms used by pathogens
