A Repeat Dose Study of the Dexmedetomidine Transdermal System in Healthy Subjects

September 7, 2026 updated by: Teikoku Pharma USA, Inc.
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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
