About this study

Prospective, randomized, placebo-controlled, double-blinded, crossover study to investigate the effect of cannabidiol (CBD) on remifentanil-induced hyperalgesia in healthy volunteers in a well-established acute pain model. Participants are randomized according to the order of the two treatments (CBD + Remifentanil or Placebo + Remifentanil).

Read the detailed description

Opioid-induced hyperalgesia (OIH) is a clinically often neglected, but well described phenomenon. OIH could also be shown for Remifentanil in an acute pain model. As CBD showed antihyperalgesic potential in the animal model, this brings up the question if CBD might be used to prevent or diminish OIH. Until today there are no studies investigating CBD as an adjunct to remifentanil or other opioids regarding the OIH. This is however of great clinical value because CBD with its possible antihyperalgesic effect on the OIH might be a worthful adjunct for opioid based anaesthesia and analgesia.

Every participant will pass through two interventions with electrically induced pain (Koppert model). CBD will be applied orally at the beginning of the intervention. Pain, allodynia and hyperalgesia will be assessed and recorded every 10 min during the remifentanil infusion and afterwards.

Questions about this trial

What is this clinical trial studying?

A study testing CBD and Remifentanil in people with Acute Nociceptive Pain and Hyperalgesia, run by University Hospital, Basel, Switzerland at 1 site in Switzerland.

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 2 inclusion and 10 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 19 Oct 2020. 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 Switzerland. 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.

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?

Change in hyperalgesia measured by the area under the curve (AUCHyper) (time frame: from minute 100 to minute 160 after termination of remifentanil infusion). 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 NCT04059978, 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 19 Oct 2020.
