Evaluation of Phage Therapy for the Treatment of Escherichia Coli and Pseudomonas Aeruginosa Wound Infections in Burned Patients

Phase I/II Clinical Trial Randomized, Multicentric, Open Label, Standard of Care (Silver Sulfadiazine) Controlled Aiming at Assessing Tolerance and Efficacy of Local Bacteriophage Treatment of Wound Infections Due to E. Coli or P. Aeruginosa in Burned Patients Using Pherecydes Pharma Anti-Escherichia Coli and Anti-Pseudomonas Aeruginosa Bacteriophages GMP Produced Cocktails . This Project is a European Research & Development (R&D) Project Funded by the European Commission Under the 7th Framework Programme for Research and Development Involving 7 Clinical Sites in EU.

The objective of PHAGOBURN is to assess tolerance and efficacy of local bacteriophage treatment of E. coli or P. aeruginosa wound infections in burned patients.
