About this study

Official title: Double Blinded Randomized Placebo Controlled Study on Mental Effects of Analgesic Drugs

The objective of the present study is to study paracetamol effects on social pain and empathy under standardized international conditions (ICH-GCP) for planning, conduction and reporting of clinical pharmaceutical studies in humans. The study included MRI imaging of brain activity, analysis of genomic biomarkers potentially explaining interindividual variation. It is controversial whether the effects are of immediate nature or develop during a period of about 10 days. Therefore, the study is separated into two study phases. Single dosing (SD) is applied in study phase 1 and multiple-dosing (MD) in study phase 2. The study compares paracetamol with placebo and in the study phase 1 also with ibuprofen as analgetically active control.

What is being measured

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

  1. Effect of paracetamol and ibuprofen on social pain and empathy

    Primary outcome is defined as the composite score of standardized emotional scenarios and the hurt feeling scale.

    Measured: 8 hours

  2. Effect of paracetamol on social pain and empathy

    Primary outcome is defined as the composite score of standardized emotional scenarios and the hurt feeling scale.

    Measured: 14 days

Secondary outcomes (6)
  1. Psychological effects of paracetamol and ibuprofen

    Interindividual variation of analgesic effects measured using fMRI. MRI will be performed to reflect differences in brain activation by Psychometric test.

    Measured: 8 hours

  2. Pharmacokinetics effects of paracetamol and ibuprofen

    Blood samples for determination of study drug concentrations in plasma will be taken at different time-point. This will be used to calculate Maximum Plasma Concentration (Cmax).

    Measured: 8 hours

  3. Pharmacogenes roles in paracetamol and ibuprofen metabolism

    Genetic analysis of relevant genes responsible for paracetamol and ibuprofen Absorption, Distribution, Metabolism and Excretion (ADME).Healthy volunteers will provide a blood sample for molecular genetic analyses of the various candidate genes, e.g. drug transporters and metabolizing enzymes. This will shed light on the interindividual variation of analgesic effects.

    Measured: 8 hours

  4. Psychological effects of paracetamol

    Interindividual variation of analgesic effects measured using fMRI. MRI will be performed to reflect differences in brain activation by Psychometric test.

    Measured: 14 days

  5. Pharmacokinetics effects of paracetamol

    Blood samples for determination of study drug concentrations in plasma will be taken at different time-point. This will be used to calculate Maximum Plasma Concentration (Cmax).

    Measured: 14 days

  6. Pharmacogenes roles in paracetamol metabolism

    Genetic analysis of relevant genes responsible for paracetamol Absorption, Distribution, Metabolism and Excretion (ADME). Healthy volunteers will provide a blood sample for molecular genetic analyses of the various candidate genes, e.g. drug transporters and metabolizing enzymes. This will shed light on the interindividual variation of analgesic effects.

    Measured: 14 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Paracetamol and Ibuprofen in people with Empathy, run by Prof. Jürgen Brockmöller at 1 site in Germany.

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 6 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 11 Jun 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 Germany. 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 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.

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

Are results available for this study?

Results are not available in the source record.

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

Contact Jürgen Brockmöller, Prof. (+49 (0) 551 39-53 11, jbrockm@gwdg.de), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Effect of paracetamol and ibuprofen on social pain and empathy (time frame: 8 hours). The study lists 2 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 11 Jun 2020.
