Armata Pharmaceuticals, Inc. is a clinical-stage biotechnology company focused on the development of pathogen-specific bacteriophage therapeutics for the treatment of antibiotic-resistant and difficult-to-treat bacterial infections using its bacteriophage-based technology. It is developing and advancing a broad pipeline of natural and synthetic phage candidates, including clinical candidates for Pseudomonas aeruginosa, Staphylococcus aureus, and other pathogens. It is advancing two lead candidates, such as AP-PA02 and AP-SA02, to address both chronic and acute bacterial infections. Its lead phage candidate, inhaled AP-PA02, focused primarily on the treatment of chronic pulmonary infections due to Pseudomonas aeruginosa. In parallel, it has an acute bacterial infection clinical development plan focused on Staphylococcus aureus bacteremia, a difficult-to-treat and often life-threatening infection. Its AP-PA03 is focused on the treatment of acute ventilator-associated pneumonia.
