Abstract: 

Purpose: The Acute Cystitis Symptom Score (ACSS) used in a clinical trial comparing the phytodrug Canephron (R) N (BNO 1045) with an antibacterial agent (fosfomycin trometamol [FT]) in the treatment of acute uncomplicated cystitis (AC) in women was evaluated as a patient-reported outcome measure in a post hoc analysis.

Materials and Methods: This double-blind, randomized, multicenter, phase III noninferiority trial was performed in 51 centers in Europe. The ACSS questionnaire was used to assess severity and course of symptoms.

Results: The post hoc analysis included 325 patients treated with BNO 1045 and 332 patients treated with FT (total of 657 patients). The mean sum-scores of the ACSS-typical domain were comparable between groups on day 1 (BNO 1045: 10.2; FT: 10.1), and then decreased on day 4 (BNO 1045: 5.1; FT: 4.5), at end of treatment on day 8 (BNO 1045:2.1; FT: 2.1), and at late follow-up on day 38 (BNO 1045: 0.8; Fr: 0.9). Predefined thresholds using the scoring system of the ACSS could be established and validated to define "clinical cure."

Conclusions: Evaluating not only antibacterial but also nonantibacterial agents indicated for the treatment of AC in women, clinical criteria for diagnostics, and measures of patient-reported outcomes are more important as main objectives than microbiological criteria. In this post hoc evaluation, we showed that the ACSS questionnaire, validated in several languages, has the potential to be used as a suitable instrument for diagnostics and patient-reported outcomes in well-designed, international, clinical studies investigating different treatment modalities of uncomplicated urinary tract infections.
