Preliminary results of a phase I/II study of sodium pentosanpolysulfate in the treatment of chronic radiation-induced proctitis.
This is a report of a phase I/II study of 13 patients treated with sodium pentosanpolysulfate (PPS) for chronic radiation-induced proctitis. A complete response was obtained in 82%, a partial response occurred in 9%, and 9% failed to respond to therapy. No significant toxicity was observed. It is concluded that PPS is an effective treatment for chronic radiation-induced proctitis and a phase III randomized, double-blind study of PPS versus placebo is planned.
