Chronic Widespread Pain and White Blood Cell Activation

Widespread Chronic Pain Clinical Trial

Official title: Proof of Concept Trial to Test the Efficacy of Treatment With Ketotifen on Pain Sensitivity and Association Between Level of Activity and Reactivity of White Blood Cells and Pain Sensitivity in Teenagers With Chronic Widespread Pain

Status Completed

Clinical Trial Summary

Our goal is to conduct a proof-of-concept trial to test the efficacy of KF treatment in adolescents with severe CWP not responding to the standard of care (SOC) treatment program in a multidisciplinary tertiary care chronic pain clinic. The changes associated to the interventions (KF or placebo) will be quantified using the Patients' Global Impression of Change (PGIC) scale after 16 weeks of treatment. Secondary, we aim to evaluate the effects of KF on the pain sensitivity, physical and emotional functioning, and we will also explore the potential biological underlying mechanisms.

Clinical Trial Description

We have designed a proof-of-concept (POC) trial composed of three arms. The first two arms will be a randomized, controlled, double-blind, parallel-group study, designed to assess the potential efficacy of KF for the treatment of pain and associated symptoms in adolescent with CWP. The third arm will consists of assessing standard of care (SOC) data from patients who do not wish to participate in the study, but agree to allow us to use their SOC data to be compared with that of patients participating in the study. This arm will help to evaluate the potential beneficial effect of being part of the study ("placebo" effect) receiving a new treatment for a condition where the SOC have limited success rate. ;
