Bacteriophages are viruses that selectively infect and destroy specific bacteria, and the company’s programs were aimed at addressing bacterial infections, including those caused by antibiotic-resistant pathogens. Its development pipeline included AB-SA01, an investigational phage therapy targeting Staphylococcus aureus, and AB-PA01, designed to target Pseudomonas aeruginosa. These programs were being evaluated for potential use in serious and chronic infections, including respiratory infections associated with cystic fibrosis. AmpliPhi operated as a clinical-stage biotechnology company and primarily focused on advancing its phage therapy candidates through research and clinical development rather than marketing approved products. In 2019, the company changed its name to Armata Pharmaceuticals, Inc., reflecting its continued focus on precision phage therapeutics.AI Generated. May Contain Errors.
