About this study

Official title: Effects of a Single Dose of Amisulpride on Functional Brain Changes During Reward- and Motivation-related Processing

This study is designed to investigate effects of a single dose of amisulpride on functional brain changes during reward- and motivation-related processing and at rest in healthy volunteers (HV) and in patients with Major Depressive Disorder (MDD).

Read the detailed description

Double blind, placebo-controlled, randomized, single dose, parallel-group design The study is designed to investigate effects of a single dose of amisulpride on functional brain changes during reward- and motivation-related processing and at rest. Measurement of functional brain changes will occur after a single dose of amisulpride or placebo in HV and patients with MDD. It is hypothesized that functional brain changes previously linked to reward- and motivation-related processing require dopaminergic signaling and are diminished in MDD compared to HV. In MDD, but not in HV, treatment with a single low dose (100 mg) amisulpride should increase brain activation associated with reward- and motivation-related processing. To test these hypotheses, we will implement a randomized, placebo-controlled, parallel- group design with 4 treatment arms (MDD/placebo, MDD/amisulpride, HV/placebo and HV/ amisulpride). All subjects will undergo MRI scanning sessions at Visit 3 and Visit 4. Treatment with amisulpride or matching placebo will occur 3.5 to 4 hours before the start of each scanning session. Time of treatment will be standardized across subjects.

At Visit 3 and Visit 4, blood samples will be taken 30 minutes pre-dose, and 1 hour, 3.5 to 4 hours, and 4.5 to 5 hours after oral drug administration to determine target plasma levels of amisulpride.

The study is composed of 4 outpatient visits: Screening, baseline and 2 scanning sessions.

What is being measured

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

  1. BOLD fMRI parameter estimates

    Blood oxygen level dependent (BOLD) fMRI parameter estimates (ß-weights within the GLM analysis) will be extracted from task-related regions of interest (average %BOLD signal change and 90th percentile thereof within ROIs) under the following task-specific contrasts:

    Monetary Incentive Delay (MID) task:

    Contrast of 'High-gain'vs. 'No-gain' condition during the task CUE period ROIs ventral striatum (including nucleus accumbens)

    Measured: during MID task at treatment day 1

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Amisulpride Pill in people with Major Depressive Disorder, run by Simone Grimm 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 9 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 24 Nov 2023. 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?

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?

BOLD fMRI parameter estimates (time frame: during MID task at treatment day 1). 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 NCT05347199, 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 24 Nov 2023.
