Overview
Brief Summary
A randomized, double-blind, placebo-controlled, multicenter, parallel group study of the safety and efficacy of Hydrocortisone Acetate Suppositories, 25 mg compared to placebo suppositories in the treatment of symptomatic internal hemorrhoids.
Detailed Description
STUDY DESIGN: 25 mg hydrocortisone suppositories administered twice daily compared to a vehicle placebo in approximately 100 subjects with symptomatic internal hemorrhoids. Subjects will be randomized in a 1:1 ratio (Test product: placebo). The study will consist of 2 periods: 1. Treatment Period (2 weeks/ Days 1-14) 2. Follow-up Period (2 weeks/ Days 15-28) The visits are as follows: Visit 1 (Day 1 Baseline/Randomization) Visit 2 (Day 8±1, Interim Visit) Visit 3 (Day 15±2, End of Treatment Visit) Visit 4 (Day 29±3, End of Study Visit) ENDPOINTS: 1. Clinician Reported Outcome (ClinRO) - Anoscopy (Visits 1, 3). Anoscopy - Visual assessment of hemorrhoids. Video of the procedure will be recorded for blinded central reading and assessment 2. Patient Reported Outcome: Subjects will use Daily Diaries to record the time and date of each medication application, concomitant medication and adverse events. The subjects will complete the Subject Questionnaire at Visits 1, 2, 3 and 4 (or early termination) and daily between visits.

Outcomes
Primary Outcomes
Reduction in Swelling
Time Frame: Day 15
Reduction in the swelling of internal hemorrhoid was measured by anoscopy. Visual assessment of hemorrhoids was performed at end of treatment. Video of the procedure will be recorded for blinded central reading and assessment. Swelling was graded on a scale from "0 - None" to "4 - Very Severe". Numeric grades and their changes from baseline are summarized descriptively by visit and treatment group. Changes from baseline will be compared between the treatment groups. Mean difference between the groups and its 95% confidence interval will be displayed at Visit 4, along with the p-value from the two-sample t-test.
Reduction in Itching Severity
Time Frame: Day 15
Patient-reported outcome (PRO) was collated and analyzed by deploying the Internal Hemorrhoid Sign and Symptom Assessment (IHSSA) questionnaire. The patients updated the questionnaire on a daily basis between visits 1-5. Responses to each item were averaged across each period. The mean score from the Screening period was considered the baseline score. Mean scores and their changes from baseline were summarized. Itching was scored from on 0-4 scale (0 =No itching, 1 = A little itching, 2 =Moderate itching, 3 = A lot of itching, 4 = Worst itching that you could imagine
