About AmpliPhi Biosciences

AmpliPhi Biosciences Corporation is a biotechnology company pioneering the development and commercialization of therapies for antibiotic-resistant infections using bacteriophage-based technology. In May 2017, AmpliPhi announced a new strategic emphasis on developing precisely targeted and personalized bacteriophage therapies for patients with serious or life-threatening antibiotic-resistant infections. AmpliPhi has reported results from two Phase 1 clinical trials of AB-SA01, one for the treatment of S. aureus in chronic rhinosinusitis patients (safety and preliminary efficacy) and one to evaluate the safety of AB-SA01 when administered topically to the intact skin of healthy adults.

About Bacteriophage

Bacteriophages, or more simply “phages,” are the natural predators of bacteria and are thought to be the most abundant life form on earth. Over eons, phages have evolved an incredible diversity of specialist strains that typically prey upon just one strain of bacteria, enabling phage therapies to precisely target pathogenic bacteria while sparing the beneficial microbiota. Phages can infect and kill bacteria, whether they are antibiotic-resistant or not, and even when they have formed protective biofilms.
