International Team Issues First Guidelines for Personalized Phage Therapy

· Science

An international team of scientists has released the first coordinated guidelines for personalized phage therapy, a treatment that uses viruses to target and kill antibiotic-resistant bacteria. The guidelines aim to provide a roadmap for safely bringing this still-experimental approach into clinical use against deadly superbugs. Phage therapy has long attracted interest as a potential answer to rising antimicrobial resistance, but until now it has lacked standard protocols covering how phages are selected, prepared and administered to individual patients. The document sets out consistent practices for researchers and clinicians working on personalized treatments. Its release signals a step toward moving phage therapy from ad hoc, case-by-case use into a more regulated and reproducible clinical pathway for patients with infections that no longer respond to conventional antibiotics.

Why it matters：Standardized guidance is a prerequisite for turning an experimental niche into a reproducible clinical option, and it comes as antimicrobial resistance pushes drugmakers and regulators to look beyond conventional antibiotics.

Key points

  • The approach uses viruses that specifically target and kill harmful bacteria.
  • The guidelines are the first coordinated framework for personalized phage therapy.
  • Phage therapy remains experimental but is aimed at antibiotic-resistant infections.
