Trial summary

Long-term use of opioids for chronic pain is a growing health and social problem, mainly because of the risk of dependence. Buprenorphine/naloxone is used as substitution therapy for opioid dependence. This substitution therapy in patients with opioid dependence lessens withdrawal symptoms and craving.

About this study

Official title: Effectiveness of Buprenorphine/Naloxone in Patients With Chronic Pain and Iatrogenic Opioid Dependence

Long-term use of opioids for chronic pain is a growing health and social problem, mainly because of the risk of dependence. Buprenorphine/naloxone is used as substitution therapy for opioid dependence. This substitution therapy in patients with opioid dependence lessens withdrawal symptoms and craving. There is limited research on the effectiveness of buprenorphine/naloxone in patients with chronic pain and iatrogenic opioid dependence. The primary aim of this study is to investigate the effectiveness of buprenorphine/naloxone in patients suffering from chronic pain and an iatrogenic induced dependence on opioids. This study will investigate the effects of opioid substitution by buprenorphine/naloxone in patients suffering from chronic pain using long-term opioids, with pain and withdrawal symptoms as primary outcome measures. Secondary outcome measures will be craving, substance use, psychiatric comorbidity and quality of life.

Read the detailed description

This is a prospective open-label observational cohort study (exploratory pilot). Investigators will include 20 patients between 18 and 65 years with chronic pain and dependence on opioids, who were referred by their physician for replacement of opioids to buprenorphine/naloxone. Exclusion criteria are contraindications for buprenorphine/naloxone and patients with psychiatric disorders requiring acute treatment. The degree of pain and withdrawal symptoms will be assessed by the Quantitative Sensory Testing (QST) measurement and the following questionnaires: Visual Analog Scale (VAS), Objective Withdrawal Scale (OWS) and Subjective Withdrawal Scale (SWS). Secondary, craving and substance use/degree of opioid dependence will be studied using the Current Opioid Misuse Measure (COMM) and Obsessive Compulsive Drug using Scale (OCDS). Psychiatric comorbidity will be assessed using the following questionnaires: Depression, Anxiety and Stress Scale (DASS), Personality Inventory for DSM-5 (PID 5-BF), The 20-item Toronto Alexithymia Scale (TAS-20), Inventory of Depressive Symptomatology (IDS), the Perseverative Thinking Questionnaire (PTQ) and Mini International Neuropsychiatric Interview (MINI). These questionnaires are part of the standard assessment at the department of psychiatry at the Radboud University Medical Centre, Nijmegen. The EuroQol five dimensions questionnaire (EQ5D) will be used to assess the quality of life. During the replacement of opioids to buprenorphine/naloxone, the buprenorphine/naloxone protocol will be used.

Questions about this trial

What is this clinical trial studying?

An observational study of Chronic Pain, run by Radboud University Medical Center at 1 site in Netherlands.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 4 Sep 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

How can a doctor refer a patient or contact the research team?

Contact Steffie van Rijswijk, MSc (steffie.vanrijswijk@radboudumc.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pain with QST baseline and change from baseline from QST at 2 months (time frame: baseline and change from baseline from QST at 2 months). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
