What is being measured

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

  1. Time to reach a z-score of absolute power >2 and maintained for at least 60 seconds in the combined spindle and β1 frequency bands within the first 60 minutes of study intervention administration of Staccato alprazolam in Group 1

    Time to reach a z-score of absolute power >2 is derived from the z-scores over time for the combined spindle and β1 frequency bands. The z-scores are calculated using an algorithm applied to the quantitative electroencephalogram (qEEG) data recorded for each study participant.

    Measured: Within the first 60 minutes of the study intervention administration on Day 1 of the Intervention Period in Group 1

  2. Time to reach a z-score of absolute power >2 and maintained for at least 60 seconds in the combined spindle and β1 frequency bands within the first 60 minutes of study intervention administration of iv midazolam in Group 1

    Time to reach a z-score of absolute power >2 is derived from the z-scores over time for the combined spindle and β1 frequency bands. The z-scores are calculated using an algorithm applied to the quantitative electroencephalogram (qEEG) data recorded for each study participant.

    Measured: Within the first 60 minutes of the study intervention administration on Day 1 of the Intervention Period in Group 1

Secondary outcomes (13)
  1. Occurrence of Treatment Emergent Adverse Events (TEAEs) from the first study intervention administration to the Safety Follow-Up (SFU) Visit/ Early Termination Visit (ETV)

    Treatment Emergent Adverse Events (TEAEs) are any untoward medical incidence in a participant after the administration of study treatment, whether or not these events are related to study treatment.

  2. Occurrence of Serious TEAEs from the first study intervention administration to the Safety Follow-Up (SFU) Visit/ Early Termination Visit (ETV)

    Results in death; Is life-threatening; Requires in patient hospitalisation or prolongation of existing hospitalisation; Results in persistent disability/incapacity; Is a congenital anomaly or birth defect; Important medical events.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Staccato Alprazolam, Midazolam and Diazepam in people with Healthy Participants, run by UCB Biopharma SRL at 1 site in United States.

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 5 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 20 Feb 2026. 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 United States. 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. 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?

Time to reach a z-score of absolute power >2 and maintained for at least 60 seconds in the combined spindle and β1 frequency bands within the first 60 minutes of study intervention administration of Staccato alprazolam in Group 1 (time frame: Within the first 60 minutes of the study intervention administration on Day 1 of the Intervention Period in Group 1). 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 20 Feb 2026.
