A Study of RO5186582 Treatment on Cytochrome P450 (CYP) 3A4 Activity in Healthy Participants

November 1, 2016 updated by: Hoffmann-La Roche
This is a non-randomized, open-label, five treatment, fixed sequence cross-over study to investigate the effect of RO5186582 treatment on CYP3A activity using midazolam as a probe CYP3A substrate, and also to assess the pharmacodynamic measures of brain electrical activity and sedation to explore the pharmacodynamic interaction between the gama-amino butyric acid (GABA)A negative allosteric modulator RO5186582 and the prototypical GABAA positive allosteric modulator midazolam. The anticipated study duration is up to nine weeks.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.
