Relative Bioavailability of Two Formulations of AKB-6548 and the Food Effect of a New Tablet in Healthy Adult Subjects

November 10, 2018 updated by: Akebia Therapeutics

A Randomized, Open-Label, Single-Dose, Three-Period Crossover Study in Healthy Adults to Assess the Relative Bioavailability of Test and Reference Formulations of AKB-6548 Tablets and to Evaluate the Effect of Food on the Bioavailability of AKB-6548

The primary purpose of this study is to compare the PK parameters of a single dose of a test tablet formulation of AKB-6548 relative to a single dose of the reference AKB-6548 tablet formulation, both treatments administered without food, and to compare the PK parameters of the test tablet formulation given under fed and fasted conditions.

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 to 55 years (Adult)

Accepts Healthy Volunteers

No
