Bacteriophages are viruses that target and infect specific bacteria, and the company pursued them as a potential complement or alternative to conventional antibiotics. Its investigational programs included AB-PA01, a bacteriophage cocktail targeting Pseudomonas aeruginosa, and AB-SA01, aimed at Staphylococcus aureus. These programs were being developed for serious infections, including those affecting the lungs. In 2019, AmpliPhi combined with C3J Therapeutics and the resulting company became Armata Pharmaceuticals. AmpliPhi therefore no longer operates as a separate publicly traded company under its former name.AI Generated. May Contain Errors.
