Recent progress toward the implementation of phage therapy in Western medicine.

ABSTRACT

Like the sword of Damocles, the threat of a post-antibiotic era is hanging over humanity's head. The scientific and medical community is thus reconsidering bacteriophage therapy (BT) as a partial but realistic solution for treatment of difficult-to-eradicate bacterial infections. Here, we summarize the latest developments in clinical BT applications, with a focus on developments in the following areas (i) pharmacology of bacteriophages of major clinical importance and their synergy with antibiotics; (ii) production of therapeutic phages; and (iii) clinical trials, case studies and case reports in the field. We address regulatory concerns, which are of paramount importance insofar as they dictate the conduct of clinical trials, which are needed for broader BT application. The increasing amount of new available data confirms the particularities of BT as being innovative and highly personalized. The current circumstances suggest that the immediate future of BT may be advanced within the framework of national BT centers in collaboration with competent authorities, which are urged to adopt incisive initiatives originally launched by some national regulatory authorities.
