AmpliPhi's product development programs target infections that are often resistant to existing antibiotic treatments. AmpliPhi is currently conducting a Phase 1 clinical trial of AB-SA01 for the treatment of Staphylococcus aureus (S. aureus)  in chronic rhinosinusitis patients and another Phase 1 clinical trial to evaluate the safety of AB-SA01 when administered topically to the intact skin of healthy adults.

About Bacteriophage
Bacteriophage are naturally occurring viruses that are highly specific for the bacterial hosts they infect. They can rapidly kill their host, amplifying themselves in the process. Bacteriophage are unaffected by antibiotic resistance and are able to disrupt bacterial biofilms. Such biofilms are a major line of defense for bacteria, contributing to antibiotic resistance. Bacteriophage are able to penetrate biofilms and replicate locally to high levels, to produce strong local therapeutic effects.
