Is this trial a fit for you?

Likely a good fit

Healthy adults aged 18–55 with a BMI between 18.5 and 30 kg/m2 who have no significant medical conditions and can give informed consent.

Probably not a fit

People with active medical problems, recent medication or supplement use, or outside the specified age/BMI ranges are unlikely to be eligible or to benefit from participating.

What this trial studies

This first-in-human, phase 1 interventional study gives single and multiple oral doses of Debio 1453P or placebo to healthy adult volunteers across multiple dose levels. Participants are monitored closely for safety and tolerability with physical exams, laboratory testing, vital signs, and ECGs, and blood samples are collected to characterize pharmacokinetics. Dose escalation between cohorts is used to identify tolerable dose ranges and pharmacokinetic profiles. The safety and PK data will guide dose selection for later studies in patients.

Why it matters

Potential benefit: If successful, the study could show Debio 1453P is safe enough for further testing and help determine appropriate dosing for future patient trials.

How similar studies have gone: First-in-human safety and PK studies of similar oral small-molecule candidates have often successfully defined safe dose ranges, but Debio 1453P itself is novel and untested in humans.

History and/or physical examination evidence of any clinically significant disease or disorder, such as cardiovascular, pulmonary, renal, hepatic, neurological, gastrointestinal, endocrine, immunological, psychiatric or mental disease or disorder, or mental or legal incapacitation, which, in the opinion of the Investigator, may either put the participant at risk for taking part in the trial, influence the results of the trial, influence the participant's ability to take part in the trial.
