Lyzor Therapeutics

Rapid, personalized therapy for hard-to-treat infections.

The Story of Us

Resistant infections are forcing hospitals into repeat procedures and long antibiotic courses; periprosthetic joint infection is one of the clearest high-stakes examples in orthopedics.

If you’re facing a PJI case where standard options keep failing, especially in biofilm-driven infection—contact us early.


Our mission is to equip clinicians with isolate-matched bacteriophage therapy for selected refractory cases. We provide a hospital-ready workflow: rapid feasibility triage, isolate logistics with your lab, and decision-ready documentation—so you can act without delays.

We’re a cross-disciplinary group spanning microbiology, computational biology, and clinical collaboration. We coordinate bacteriophage therapy on a case-by-case basis and provide matching, logistics, and clinician support. Therapy preparation is carried out in collaboration with partner laboratories and treating hospital teams.

Send case details (for clinicians)

Joint/prosthesis, suspected or confirmed PJI, what’s been done so far, antibiotics used, your timeline.

Culture a bacterial isolate

Your team samples the joint and cultures the pathogen. A viable isolate is then shipped for phage matching.
