Inclusion criteria

  1. Signed and dated written obtained before undertaking any trial-specific procedures.
  2. Be within the age range of 18 to 55 years, inclusive, at the time of screening.
  3. Have a (BMI) ≥18.5 and ≤30.0 kg/m\^2.

Exclusion criteria

Exclusion criteria

  1. History and/or physical examination evidence of any 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.
  2. Any medication (including vaccines, over the counter (OTC) and/or prescription medication, dietary supplements, nutraceuticals, vitamins and/or herbal supplements, and hormonal replacement therapy for participants) for 2 weeks or 5 half-lives of the drug, whichever is longer, prior to first administration of trial drug (except occasional paracetamol (maximum dose of 2 g/day and maximum of 10 g/2 weeks).
  3. History of chronic drug or alcohol abuse (defined as an average intake of more than 21 units of alcohol per week for males and 14 for females. 1 unit of alcohol equals approximately 250 mL of beer, 100 mL of wine, or 35 mL of spirits) in the last 2 years.
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Study arms

  • Experimental
    Part 1: Single ascending dose (SAD)

    Participants will receive a single oral dose of Debio 1453P or placebo in a sequential manner on Day 1.

    Drug: Debio 1453P · Drug: Placebo

  • Experimental
    Part 2: Multiple ascending dose (MAD)

    Participants will receive multiple oral doses of Debio 1453P or placebo from Day 1 to Day 5. Debio 1453P initial dose in this part will be based on available data from SAD part.
