Sponsor: PRS Results Training Information provided by (Responsible Party): PRS Results Training Disclaimer: The following information is fictional and is only intended for the purpose of illustrating key concepts for results data entry in the Protocol Registration and Results System (PRS). Full Text View Purpose The purpose of this study is to assess the safety and efficacy of Remuverol for treatment of Condition A. Condition Intervention Phase Condition A Drug: Remuverol Phase 3 Drug: Placebo Study Type: Interventional Study Design: Allocation: Randomized Endpoint Classification: Safety/Efficacy Study Intervention Model: Parallel Assignment Masking: Double Blind (Subject, Investigator) Primary Purpose: Treatment Official Title: A 24-Week Double-Blind Trial of Remuverol in Adults With Condition A Further study details as provided by PRS Results Training Primary Outcome Measure: • Change From Baseline in Pain on the 11-point Short Pain Scale (SPS-11) at Week 24 [Time Frame: Baseline and Week 24] [Designated as safety issue: No] SPS-11 is a validated, self-reported instrument assessing average pain intensity over the past 24 hour period. Possible scores range from 0 (no pain) to 10 (worst possible pain). Change = (Week 24 Score - Baseline score) Secondary Outcome Measures: • Response Rate - 50 Percent or Greater Reduction in Short Pain Scale (SPS-11) Score [Time Frame: 12 weeks] [Designated as safety issue: No] The response rate was defined as the number of participants with a 50% or greater reduction in SPS-11 pain score from baseline to endpoint. SPS-11 is a validated, self-reported instrument. Possible scores range from 0 (no pain) to 10 (worst possible pain). ClinicalTrials.gov is a service of the National Institutes of Health.
