Radiation Cystitis

Brief summary

The purpose of this study is to evaluate the efficacy and safety of pentosan polysulfate sodium versus placebo and in patients with radiation cystitis who have received radiation therapy in pelvic region.

Detailed description

RCT-PPS is a phase II/III study evaluating the efficacy, safety, and tolerability of pentosan polysulfate sodium (PPS) versus placebo to patients with radiation cystitis who have received radiation therapy in pelvic region. Approximately 72 patients were planned to be randomized in RCT-PPS trial in a 1:1 ratio to treatment with either PPS or placebo. Patients will receive oral treatment with 16 weeks (PPS 100mg three times a day for 8 weeks and then with PPS 100mg twice daily for another 8 weeks).
