What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of patients with clinical success as defined as clinical cure or clinical improvement

    Definition of clinical cure (both criteria must be fulfilled):

    • Resolution of signs and symptoms and
    • microbiological cure or no additional antibiotic therapy for the targeted infection necessary.

    Definition of clinical improvement (both criteria must be fulfilled):

    • Partial resolution of signs and symptoms and
    • microbiological cure or no additional antibiotic therapy for the targeted infection necessary.

    Definition of microbiological cure:

    • Elimination of the relevant pathogen(s) at the relevant site(s) of infection (at least one negative culture) or
    • in case "no sample available/indicated due to sufficient clinical response", pathogen elimination is considered.

    Time Frame:

    Time point "End of fosfomycin treatment" (EOT) is reached at the day of the last fosfomycin application in the course of the treatment schedule for the targeted infection (i.e., in case of a multiple stage treatment schedule, the end of the last fosfomycin treatment phase).

    Measured: Analysed at EOT ("End of fosfomycin treatment", up to 6 months after start of fosfomycin treatment)

    Measured: Analysed at TOC ("Test of cure", up to 6 months after start of fosfomycin treatment)

  4. Microbiological cure

    Definition of microbiological cure:
