Armata Pharmaceuticals Announces Clearance of Investigational New Drug Application to Initiate Phase 2 Clinical Trial of AP-PA02 in Non-Cystic Fibrosis Bronchiectasis

MARINA DEL REY, Calif., Feb. 22, 2022 /PRNewswire/ -- Armata Pharmaceuticals, Inc. (NYSE American: ARMP) ("Armata" or the "Company"), a biotechnology company focused on pathogen-specific bacteriophage therapeutics for antibiotic-resistant and difficult-to-treat bacterial infections, today announced that the U.S. Food and Drug Administration ("FDA") has cleared Armata's Investigational New Drug (IND) application to initiate a clinical trial of its optimized lead therapeutic candidate, AP-PA02, in a second indication, non-cystic fibrosis bronchiectasis ("NCFB"). The company plans to initiate a Phase 2 trial in 2022.   

In patients with NCFB, lung infection with Pseudomonas aeruginosa is often associated with frequent pulmonary exacerbations, reduced quality of life, and increased mortality, and may require hospital admission for treatment. Although chronic inhaled antibiotics are recommended for long-term management of NCFB with frequent exacerbations, there is currently no approved therapy.

"We are excited to gain FDA clearance to advance AP-PA02 into second respiratory indication," said Brian Varnum, Chief Executive Officer of Armata. "With this regulatory approval and our recent financing, we are well positioned to explore the clinical benefit of AP-PA02, and to advance AP-SA02 for prosthetic joint infections and AP-PA03 for pneumonia."       

In addition to the upcoming trial of AP-PA02 in NCFB, Armata is also conducting a Phase 1b/2a trial ('SWARM-P.a.') of AP-PA02 targeting Pseudomonas aeruginosa infections in cystic fibrosis patients, and a Phase 1b/2a trial ('diSArm') of AP-SA02 targeting Staphylococcus aureus bacteremia.
