About this study

Official title: A Randomized, Double-blind, Placebo-controlled Crossover Study of the Pharmacodynamic Effects, Safety, Tolerability, and Pharmacokinetics of Single Doses of HBS 104 in Acutely Sleep-deprived Healthy Participants

This is a study to evaluate the pharmacodynamic effects, safety, tolerability, and pharmacokinetics of HBS-104 in acutely sleep-deprived healthy adult participants.

Read the detailed description

Single oral doses of HBS-104 (low, medium or high doses) or matching placebo will be administered in 4 double-blind treatment periods in a crossover design. Each treatment period is 4 days in duration (Days -1 to 3) separated by a 7 to 12 day washout interval.

What is being measured

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

  1. Mean Sleep Latency as Assessed by Maintenance of Wakefulness Test (MWT)

    Measured: Day 2 of each treatment period (each treatment period is 4 days in duration [Days -1 to 3]).

  2. Karolinska Sleepiness Scale (KSS) Score

    Measured: Days 1 and 2 of each treatment period (each treatment period is 4 days in duration [Days -1 to 3]).

  3. Psychomotor Vigilance Test (PVT) Score

    Measured: Days 1 and 2 of each treatment period (each treatment period is 4 days in duration [Days -1 to 3]).

Secondary outcomes (2)
  1. Number of Participants with Treatment Emergent Adverse Events

    Measured: Up to 25 weeks

  2. Serum Concentrations of HBS-104 and Metabolites

    Measured: Days 1, 2 and 3 of each treatment period (each treatment period is 4 days in duration [Days -1 to 3]).

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing HBS-104 in people with Sleep Deprivation, run by Harmony Biosciences Management, Inc. 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 2 inclusion and 3 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: looking for participants now, as of the sponsor's last update on 30 Sep 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Clinical Trials Administrator (see email, clinicaltrials@harmonybiosciences.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Mean Sleep Latency as Assessed by Maintenance of Wakefulness Test (MWT) (time frame: Day 2 of each treatment period (each treatment period is 4 days in duration [Days -1 to 3]).). The study lists 3 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 30 Sep 2026.
