Nantes, March 22, 2022 – 7:00 am CET - Pherecydes Pharma (FR0011651694 – ALPHE), a biotechnology company specializing in precision phage therapy to treat resistant and/or complicated bacterial infections, today announces the granting of a new patent for its anti-Pseudomonas aeruginosa phages by the European Patent Office (EPO).

This new patent granted in Europe gives the Company protection until 2034 on this vast market.

Guy-Charles Fanneau de La Horie, Chairman of the Executive Board of Pherecydes Pharma, said: “Pseudomonas aeruginosa is one of the six most deadly antibiotic-resistant pathogens1. The intense work carried out by our R&D and intellectual property teams is continuing to produce very tangible results, as demonstrated by our regular press releases on patents granted in our various strategic regions, and I would like to thank them for this. Indeed, the intellectual property policy is an integral part of our corporate strategy and aims to protect our investments in precision phage therapy, one of the most promising avenues faced with the shortcomings of antimicrobial research in which Pherecydes Pharma intends to play a leading role”.

Pherecydes Pharma has an active portfolio of four patents each covering multiple phages and their variants against the target bacteria: Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia Coli. These are three of the six most deadly bacteria1 and are on the list of R&D priorities published by WHO. While some patents are still pending in certain jurisdictions, others have already been granted in major territories such as the United States, Europe, Japan, Australia, Hong Kong, Israel and China.
