Study summary

This Phase 1, 16-day Repeat dose study will evaluate the safety of a Dexmedetomidine Transdermal System (DMTS) skin system in healthy adults Subjects. Participants will receive the patch for four consecutive 4-day treatment periods. Researchers will monitor safety, drug levels in the blood, sedation effects, skin irritation, and how well the patch stays attached to the skin.

Inclusion criteria

  • Subjects must be non-smokers, as defined by cessation of smoking and consumption of no more than 2 tobacco/nicotine-containing products within 6 months prior to screening.
  • Have a body weight > 50 kg, and (BMI) of 18.0 to 38.0 kg/m2
  • Free of any dermatologic conditions (eg, psoriasis, eczema), excessive hair, skin allergies, or sensitivities that may compromise the subject's ability to wear the product at the application site for the specified duration of treatment
  • Female subjects are eligible only if all the following apply:

    1. Not pregnant, not lactating, and not planning to become pregnant during the study or for 1 menstrual cycle thereafter
    2. Surgically sterile (via hysterectomy or oophorectomy); or at least 2 years ; or have a monogamous partner who is surgically sterile; or have a same gender partner; or is using double-barrier ; or practicing abstinence; or using an insertable, injectable, transdermal, or combination oral contraceptive for 3 months prior to the study, during the study, and for 1 month following the study
  • Male subjects with female sex partners of must be surgically sterile or commit to use a reliable method of birth control during the study and for 3 months following the study.

Exclusion criteria

Exclusion Criteria:

  • History of allergy or to dexmedetomidine or dexmedetomidine hydrochloride.
  • Skin abnormality (eg, scar, tattoo) or unhealthy skin condition (eg, burns, wounds) at the DMTS application site, according to examination by the investigator at screening or admission to the clinic.
  • History of or positive test results for the (HIV), , or .
  • History of seizures.
  • Use of any prescription or non-prescription drugs (except acceptable forms of , paracetamol up to 2 g per day for no more than 3 consecutive days, and ibuprofen up to 1.2 g per day for no more than 3 consecutive days for headache or dysmenorrhea, etc., per investigator discretion) within 14 days prior to study drug administration and throughout the study, unless in the opinion of the investigator or designee, the product will not interfere
  • Significant history of postural hypotension, or history of severe dizziness or fainting upon standing in the opinion of the investigator.
  • Donation of blood or loss of blood (> 100 mL) within 30 days prior to study drug administration.
  • Had symptoms of an upper respiratory tract infection within 14 days prior to dosing of the study drug
Terms in these criteria, in plain language(9)

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.

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.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

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).

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

Ran from Sep 2026 to primary completion in Oct 2026, 1 month.

Since we started tracking on Sep 25, 2026, the dates moved once, on Nov 9, 2026: start Oct 2026 → Sep 2026, primary completion Dec 2026 → Oct 2026 and completion Dec 2026 → Oct 2026.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
