What is being measured

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

  1. Difference between the total number of errors adjusted for stages that subjects did not complete in the paired associate learning test (PALTEA28), post-ketamine minus the PALTEA28 pre-ketamine

    Measured: up to 22 days

Secondary outcomes (2)
  1. Difference between the between errors in the spatial working memory test (SWMBE468), post-ketamine minus the SWMBE468 pre-ketamine

    Measured: up to 22 days

  2. Difference between the Rapid Visual Information Processing test A' (RVPA), post-ketamine minus the RVPA pre-ketamine

    Measured: up to 22 days

Individual data sharing
No: Clinical studies sponsored by Boehringer Ingelheim, phases I to IV, interventional and non-interventional, are in scope for sharing of the raw clinical study data and clinical study documents. Exceptions might apply, e.g. studies in products where Boehringer Ingelheim is not the license holder; studies regarding pharmaceutical formulations and associated analytical methods, and studies pertinent to pharmacokinetics using human biomaterials; studies conducted in a single center or targeting rare diseases (in case of low number of patients and therefore limitations with anonymization).

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing BI 474121 and Ketamine hydrochloride in people with Healthy, run by Boehringer Ingelheim.

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 5 inclusion and 8 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The record says: withdrawn, as of the sponsor's last update on 1 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.

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 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 was withdrawn before enrolling participants, so there are no results.

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?

Difference between the total number of errors adjusted for stages that subjects did not complete in the paired associate learning test (PALTEA28), post-ketamine minus the PALTEA28 pre-ketamine (time frame: up to 22 days). 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 1 Aug 2022.
