Describes the structure of phage Pa223, which is included in Armata's multi-phage anti-Pseudomonas clinical candidate, AP-PA02 , /PRNewswire/ -- Armata Pharmaceuticals, Inc. (NYSE American: ARMP) ("Armata" or the "Company"), a clinical-stage biotechnology company focused on the development of high-purity, pathogen-specific bacteriophage therapeutics for the treatment of antibiotic-resistant and difficult-to-treat bacterial infections, today announced a paper in the Journal of Molecular Biology (JMB). The publication, titled, "High-resolution Cryo-EM Analysis of the Therapeutic Pseudomonas Phage Pa223," describes the structure of phage Pa223, which is included in Armata's five-phage clinical cocktail, AP-PA02. Armata is developing AP-PA02 as a potential treatment for chronic respiratory infections in people with cystic fibrosis and non-cystic fibrosis bronchiectasis (NCFB). AP-PA02 has shown promising results in two Phase 2 clinical trials to date - SWARM-P.a. and Tailwind. "The ability to collaborate with brilliant bench scientists and clinical partners simultaneously at universities and medical centers is critically important," stated Dr. Deborah Birx, Chief Executive Officer of Armata, and co-author of the paper. "With this latest scientific research, we further advanced our collective understanding of fundamental phage biology, specifically, how structural characteristics may impact clinical utility against a dangerous bacterial pathogen. This groundbreaking structural analysis may be beneficial in informing future development plans to bring further innovation to patients suffering from serious bacterial infections."    Dr. Gino Cingolani, Anderson Family Endowed Chair in Medical Education, Research & Patient Care and Professor in the Department of Biochemistry and Molecular Genetics, The University of Alabama at Birmingham, and senior author of the paper, stated, "Breakthrough advances in cryogenic electron microscopy (cryo-EM), bioinformatics, and proteomics have allowed us to gain an understanding of phage structure and composition at near atomic resolution like never before. In this study, we provide the first structural description of a phage from the Bruynoghevirus genus, in this case Pa223, which has been utilized in experimental phage therapy. Phages like Pa223 are valuable due to their broad host range and high lytic activity against both planktonic and biofilm-associated bacteria. Leveraging cryogenic electron microscopy, we developed a high-resolution structural atlas of Pa223 and identified several aspects of its biology that may have potential applications for other phages used in clinical cocktails. These learnings have the potential to accelerate the development of phage-based therapeutics for a broad range of clinical uses." The full paper can be found here.
