Armata Pharmaceuticals (NYSE American: ARMP) announced the publication of a research paper in the Journal of Molecular Biology detailing the structural analysis of phage Pa223, a component of their clinical candidate AP-PA02. The study provides the first structural description of a phage from the Bruynoghevirus genus using advanced cryogenic electron microscopy.

AP-PA02, a five-phage cocktail, is being developed to treat chronic respiratory infections in cystic fibrosis and non-cystic fibrosis bronchiectasis (NCFB) patients. The therapeutic has demonstrated promising results in two Phase 2 clinical trials - SWARM-P.a. and Tailwind. The structural insights gained from this research may inform future development of phage-based therapeutics.
