Efficacy and Safety Study to Treat Subjects With Symptomatic Internal Hemorrhoids

• Status: Terminated
• Trial end date: 2012-06-01
• Target enrollment: 0
• Participant gender: All

Summary

Primary Objective:

To evaluate the effect of iferanserin ointment on cessation of bleeding when administered intra-anally twice daily (BID) for 7 or 14 days in subjects with symptomatic internal hemorrhoids.

Methodology:

Double-Blind: Phase 3, multicenter, double-blind, randomized, parallel group, placebo-controlled part of the study. Extension: Multicenter, open-label part of the study.

Study Treatment Duration:

Double-Blind: 28 days (14-day treatment period and a 14-day follow-up period). Extension: 12 months (open-label part of the study in which there will be a scheduled visit every three months. Subjects who have recurrence(s) of their symptomatic internal hemorrhoids will be treated with open-label iferanserin for 7 days followed by a 21-day follow-up period).

Criteria for Evaluation:

Primary Endpoint:

The primary endpoint is the cessation of bleeding by the end of Day 7 that persists for the remainder of the treatment period (through Day 14).

• Phase: Phase 3
• Accepts Healthy Volunteers?: No
