Efficacy of CLR Compared to Fosfomycin Trometamol in Acute Lower uUTIs

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02639520
Recruitment Status : Completed
First Posted : December 24, 2015
Last Update Posted : July 28, 2017

Brief Summary:
To demonstrate non-inferiority of a non-antibiotic therapy with CLR versus an antibiotic treatment with fosfomycin trometamol in women suffering from acute lower uUTIs as measured by the proportion of patients who received an additional antibiotic treatment for acute lower uUTIs during the trial.

Condition or disease Intervention/treatment Phase
Urinary Tract Infection Drug: Canephron® N Drug: Fosfomycin trometamol Drug: Canephron® N-placebo Drug: Fosfomycin trometamol-placebo Phase 3

Detailed Description:

The trial is designed as a comparison of two different modes of action in order to look for alternatives to antibiotic treatment of uncomplicated UTIs. Treatment with CLR is a nonantibiotic therapy and is compared to an antibiotic treatment. Thus, the trial aim is to reduce antibiotics use and moreover to reduce the pressure of developing bacterial resistance against antibiotics due to widespread use, which is an additional advantage of the CLR therapy.

The trial results are expected to demonstrate that antibiotic prescriptions in women for treatment of lower uUTIs can be reduced by an alternative and safe non-antibiotic treatment.

Arm Intervention/treatment
Active Comparator: Group Canephron® N
Canephron® N & fosfomycin trometamol-placebo
Drug: Canephron® N
2 tablets 3 times a day for 7 days

Drug: Fosfomycin trometamol-placebo
1 sachet of 8 g of granules; one single dose on Day 1

Active Comparator: Group Fosfomycin Trometamol
Canephron® N-placebo & fosfomycin trometamol
Drug: Fosfomycin trometamol
1 sachet of 8 g of granules; one single dose on Day 1

Drug: Canephron® N-placebo
2 tablets 3 times a day for 7 days

Primary Outcome Measures :
  1. Intake of any additional antibiotic medication for acute lower uUTIs between Visit 1 and Visit 4 [ Time Frame: within 38 days after Visit 1 (=day 1) ]

    For patients with consistent or worsening of acute lower uUTI symptoms during the trial the investigator may offer an additional antibiotic therapy at any post-baseline visit. In this case, the patient will be considered a "treatment failure" due to lack of efficacy of the IMP. The alternative antibiotic therapy offered to the patient and the reason for the alternative therapy (i.e., persisting or recurrent symptoms) is to be documented.

    The primary variable for the assessment of efficacy is the proportion of patients who received additional antibiotic treatment for acute lower uUTI between Visit 1 and Visit 4 (defined as AB-rate).
