Study Summary

This proposal will take an important first step in the study of phage therapy for treatment of recurrent urinary tract infection (rUTI) in female kidney transplant recipients (KTR); a common condition that is associated with increasing multidrug resistance, sickness, loss of kidney function and death. The investigators will conduct a randomized phase I/II pilot clinical trial of targeted phage therapy versus placebo in asymptomatic female KTR with a history of rUTI due to Escherichia coli to assess safety, tolerability, and feasibility of this approach, possible efficacy, and changes in the gut and urinary microbiome during the 180 days of the study. This highly innovative and impactful proposal will provide proof of concept data and also inform the design of a subsequent larger phase III clinical trial of phage therapy for rUTI treatment in KTR and will have broad downstream effects within the fields of infectious diseases and transplantation.

Primary Outcome

Safety of phage administration will be assessed by the incidence of adverse events (AE) as assessed by CTCAE v4.0. As this is a phase 1/ 2 pilot clinical study, the primary outcome is safety and tolerability of the IP.
