HBS-104 single doses in acutely sleep-deprived healthy adults
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
Run by Harmony Biosciences Management, Inc. · NCT07848659 · Data updated 2026-11-12
This study tests whether a single dose of HBS-104 is safe and how it behaves in the body when given to healthy adults who are acutely sleep-deprived.

Is this trial a fit for you?
✓Likely a good fit
Healthy adults who are acutely sleep-deprived and willing to participate in a crossover study with multiple periods.
✕Probably not a fit
Individuals who do not meet health criteria or who experience adverse effects or non-compliance may not benefit from the study findings.

What this trial studies
This Phase 1, randomized, double-blind crossover trial will compare low, medium, and high oral doses of HBS-104 to placebo in healthy adults who are acutely sleep-deprived. Participants receive a single dose during each of four treatment periods (Days -1 to 3) with 7–12 days between periods to wash out the drug. The study assesses pharmacodynamic effects, safety, tolerability, and pharmacokinetics after dosing under sleep-deprived conditions. A single-site sponsor clinical location in Eatontown, New Jersey conducts all procedures.
Why it matters
Potential benefit: If successful, the findings may inform dosing and safety for future sleep-related studies of HBS-104 in similar populations.
How similar studies have gone: Other early-stage studies with sleep-modulating agents have shown pharmacodynamic and safety signals in healthy sleep-deprived individuals, though results depend on the compound.
