Trial summary

While the analgesic effects of opioids are well known, evidence suggest that there are differences in the adverse dizziness of the different opioid types, which may influence the gait function differently. However, this has not been investigated scientifically under controlled conditions. Read more about this study

About this study

While the analgesic effects of opioids are well known, evidence suggest that there are differences in the adverse dizziness of the different opioid types, which may influence the gait function differently. However, this has not been investigated scientifically under controlled conditions. Normal gait function is characterized by cyclic movements with a high degree of predictability. As such, the amount of kinematic variability can provide important information about a condition or an intervention that may affect the gait function . Three-dimensional gait analysis is a recognized method to assess changes in stride-to-stride variability associated with a medical condition or caused by an intervention. Thus, opioid induced changes in gait variability, and possible differences between opioid types, can be assessed objectively from differences in the variability of movements obtained from a three-dimensional gait analysis.

The purpose of this study is to investigate differences in gait variability induced by two different single-dose opioid formulations and an inert placebo in healthy volunteers and knee osteoarthritis patients.

Read the detailed description

The study is designed as an experimental single center, double-blind treatment, cross-over study with inert placebo, Tapentadol (Palexia Depot), and Tramadolhydrochlorid (Mandolgin Retard), with a minimum of 7days wash-out periods.

At day 1 (Visit 1), baseline measurements are carried out before tablet administration. Immediately after baseline measurements one tablet is administered, and hourly measurements are performed for 6 hours. Subsequently all participants enter a minimum 7 day washout period, after which they return to the facility to repeat the procedures at Visit 2 (day 8+) and Visit 3 (day 15+). The order of treatments will be randomized (1:1:1).

What is being measured

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

  1. Changes in Gait variability

    Three dimensional gait analysis during 6 minutes of continuous treadmill walking.

    Measured: every hour from pre-tablet administration (hour 0) to hour 6

Secondary outcomes (2)
  1. Self reported dizziness

    Current dizziness is assessed by means of a 100 mm visual analog scale

    Measured: every hour from pre-tablet administration (hour 0) to hour 6

  2. Self reported knee pain

    Current knee pain is assessed by means of a 100 mm visual analog scale

    Measured: every hour from pre-tablet administration (hour 0) to hour 6

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Tapentadol 50 mg Oral Tablet and Tramadol Hydrochloride 100 mg Extended Release Oral Tablet in people with Opioid Induced Motor Disturbances, run by Frederiksberg University Hospital at 1 site in Denmark.

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 20 inclusion and 31 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 6 Nov 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 Denmark. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Changes in Gait variability (time frame: every hour from pre-tablet administration (hour 0) to hour 6). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03121547, which also lists 1 linked publication.

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 6 Nov 2017.
