Clinical Trial Summary

Multicenter, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of XC243 in patients with exacerbation of chronic cystitis. It is planned to include patients with chronic cystitis in 4 parallel groups, who will receive XC243 at a dose of 25 mg per day, 50 mg per day, 75 mg per day or placebo for 7-10 days. Efficacy will be assessed by time from first study treatment to resolution of the symptom "Pain, discomfort or burning when urination " assessed on a visual-analog scale (VAS).

Description:

The study will be conducted in 8 centers. The study will include the following periods: screening (1 day), treatment period (up to 10 days), follow-up period (7 days). Upon completion of screening, patients will be randomized to 4 groups in the ratio 1:1:1:1: XC243 at a dose of 25 mg per day, 50 mg per day, 75 mg per day or placebo group. Also, all patients will be prescribed furasidin daily at the same time, 2 capsules (total dose 100 mg) 3 times a day after meals. On day 8 the investigator will assess the symptoms of cystitis and decide whether to discontinue or prolong a course of therapy with XC243 and furasidin for up to 10 days.
