Company Overview

AmpliPhi Biosciences Corporation was a clinical-stage biotechnology company focused on developing bacteriophage therapies for bacterial infections, particularly infections caused by antibiotic-resistant pathogens. Bacteriophages are naturally occurring viruses that selectively infect and destroy bacteria, offering a potential alternative or complement to conventional antibiotics.

The company developed a proprietary phage-discovery and development platform and advanced product candidates including AP-PA01, an investigational therapy targeting Pseudomonas aeruginosa infections, and AP-SA02, which targeted Staphylococcus aureus. Its research was directed toward serious respiratory and systemic infections, including conditions affecting patients with cystic fibrosis and other vulnerable populations.

AmpliPhi operated as a development-stage biotechnology company serving the pharmaceutical and healthcare markets through its research and clinical programs rather than through commercial products. In 2019, the company changed its name to Armata Pharmaceuticals, Inc. and continued its bacteriophage development activities under that identity. Todd R. Patrick served as chief executive officer during AmpliPhi’s transition to Armata.
