M2 PHARMA-March 14, 2018-AmpliPhi, US Department of Veterans Affairs Partner to Expand Access to Bacteriophage Therapeutics
AmpliPhi Biosciences Corporation, a clinical-stage biotechnology company focused on precisely targeted bacteriophage therapeutics for antibiotic-resistant infections, today announced the presentation of in vivo preclinical data showing AB-PA01 reduces biofilm in a Pseudomonas aeruginosa preclinical model.
The data presented demonstrate the potential of bacteriophage therapeutics by clearly showing AB-PA01's effectiveness in reducing biofilm in vivo, a major obstacle in the treatment of Pseudomonas aeruginosa and its associated symptoms," said Peter-John Wormald, M.
