Trial summary

Individuals with opioid addiction often experience serious withdrawal symptoms that may make relapse unavoidable. Tramadol, a medication that is currently used to treat pain caused by chronic conditions such as cancer or joint pain, may also be effective at reducing opioid withdrawal symptoms.

About this study

Official title: Withdrawal Suppression Efficacy of Tramadol

Individuals with opioid addiction often experience serious withdrawal symptoms that may make relapse unavoidable. Tramadol, a medication that is currently used to treat pain caused by chronic conditions such as cancer or joint pain, may also be effective at reducing opioid withdrawal symptoms. This study will evaluate the effectiveness of tramadol at reducing withdrawal symptoms in individuals addicted to opioid drugs.

Read the detailed description

Opioid withdrawal symptoms are a major contributing factor for why opioid treatment programs often fail. Individuals with severe opioid withdrawal symptoms may experience shaking, muscle and bone pain, nausea, depression, anxiety, and drug craving. Tramadol is a medication that is currently used to treat moderate to severe pain in individuals with cancer, joint pain, or pain resulting from surgery. Because of its pharmacological profile, tramadol may also be useful in treating opioid withdrawal. Further research is needed to confirm the benefits of tramadol for opioid addicts. The purpose of this study is to evaluate the effectiveness of tramadol at reducing opioid withdrawal symptoms in opioid-dependent individuals.

This 6-week inpatient study will enroll opioid-dependent individuals. Participants will be required to reside at the research clinic for the entire study. All participants will receive morphine maintenance treatment on a daily basis. Twice a week participants will take part in experimental challenge sessions in which they will be randomly assigned to receive varying doses of tramadol, naloxone, morphine, or placebo. These sessions will assess the ability of tramadol to suppress opioid withdrawal symptoms. Participants will complete performance tasks to measure psychomotor and cognitive functioning. Heart rate and blood pressure will be monitored throughout the experimental sessions. A specialized camera will also be used to assess pupillary response of the eyes. Questionnaires and self-reports will be completed to assess medication effects and withdrawal symptoms. Following the end of the study, all participants will be offered outpatient drug abuse treatment.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Opioid withdrawal symptoms (measured by Visual Analog Scale during the experimental sessions)

  2. Opioid agonist effects (measured by Visual Analog Scale during the experimental sessions)

  3. Physiological effects (measured by pulse oximeter, blood pressure, heart rate, and pupillary camera during the experimental sessions)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Tramadol, Naloxone and Morphine in people with Opioid-Related Disorders, run by National Institute on Drug Abuse (NIDA) at 1 site in United States.

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 4 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: finished, as of the sponsor's last update on 12 Jan 2017. 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 United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Opioid withdrawal symptoms (measured by Visual Analog Scale during the experimental sessions). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Jan 2017.
