AmpliPhi Biosciences Will Utilize NIAID Preclinical Services to Advance Development of Its Targeted Therapeutic Candidate for the Treatment of Resistant Staphylococcus Aureus

SAN DIEGO–(BUSINESS WIRE)–AmpliPhi Biosciences Corporation (NYSE American: APHB), a clinical-stage biotechnology company focused on precisely targeted bacteriophage therapeutics for antibiotic-resistant infections, today announced that it will utilize the Therapeutic Development Services funded by the National Institute of Allergy and Infectious Disease (NIAID), part of the National Institutes of Health (NIH), to conduct further preclinical studies of AB-SA01. The Therapeutic Development Services program funds the provision of preclinical services for selected companies and researchers in order to advance development of promising interventional agents.

“We are pleased and encouraged by the support from the NIAID and its commitment to studying the role of bacteriophage in combating infectious diseases,” said Paul C. Grint, M.D., CEO of AmpliPhi Biosciences. “This service will help support the development of bacteriophages as a much needed treatment for antibiotic-resistant infections.”

AB-SA01 is a 3-phage investigational therapeutic being developed for treatment of serious and drug-resistant Staphylococcus aureus (S. aureus) infections. In preclinical studies, AB-SA01 demonstrated broad activity against more than 96% of global S. aureus clinical isolates, including multidrug-resistant forms. AB-SA01 has completed two Phase 1 studies and has also been administered to patients under compassionate use guidelines in the U.S. and Australia for treatment of serious and life-threatening S. aureus infections.

About AmpliPhi Biosciences

AmpliPhi Biosciences Corporation is a clinical-stage biotechnology company focused on treating antibiotic-resistant infections using its proprietary bacteriophage-based technology. AmpliPhi’s lead product candidates, AB-SA01 and AB-PA01, target multidrug-resistant Staphylococcus aureus and Pseudomonas aeruginosa, which are included on the WHO’s 2017 Priority Pathogens List. Phage therapeutics are uniquely positioned to address the threat of antibiotic-resistance as they can be precisely targeted to kill select bacteria, have a differentiated mechanism of action, can penetrate and disrupt biofilms (a common bacterial defense mechanism against antibiotics), are potentially synergistic with antibiotics and have been shown to restore antibiotic sensitivity to drug-resistant bacteria.
