About this study

Official title: Multicenter, Randomized, Double-blind, Placebo-controlled Study to Evaluate the Efficacy and Safety of XC243 in Patients With Exacerbation of Chronic Cystitis

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).

Read the detailed 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.

What is being measured

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

After 96 hours (from day 5) evaluation this symptom will be carried out 2 times a day (8-00 to 10-00 hours and from 20-00 to 22-00 hours over time).
