Study to Investigate the Influence of Hepatic Insufficiency on the Pharmacokinetics of Tozadenant

January 2, 2018 updated by: Biotie Therapies Inc.

A Two-Part, Open-Label, Single-Dose Study to Investigate the Influence of Hepatic Insufficiency on the Pharmacokinetics of Tozadenant

This is a two-part, open label, single-dose study that will evaluate the PK of tozadenant in subjects with different degrees of hepatic impairment to the PK of a single-dose of tozadenant in healthy subjects.

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.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
To evaluate the pharmacokinetics (PK) [area under the time-concentration curve] of a single-dose of tozadenant in subjects with hepatic impairment to healthy subjects.
Time Frame: up to 12 days
To evaluate the pharmacokinetics (PK) [area under the time-concentration curve] of a single-dose of tozadenant in subjects with hepatic impairment compared to the PK of a single-dose of tozadenant in healthy subjects.
up to 12 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Subjects with hepatic impairment will be evaluated for safety assessments (adverse events and treatment-related adverse events) by physical examinations.
Time Frame: up to 12 days
To evaluate the safety and tolerability of a single-dose of tozadenant in subjects with hepatic impairment by physical examinations, vital sign measurements and Columbia-Suicide Severity Rating Scale (C-SSRS) questionnaire.
up to 12 days
