Detailed Description

This is a Phase 1, open-label, 3-arm, fixed sequence, study to evaluate vadadustat as a perpetrator of drug-drug interactions (DDIs) with digoxin, adefovir and furosemide in healthy male and female subjects. Unique subjects will be enrolled into each arm of the study and enrollment will be sequential. The first 20 subjects confirmed to be eligible will be assigned to Arm 1 (digoxin), the next 16 subjects will be assigned to Arm 2 (adefovir) and the next 22 subjects will be assigned to Arm 3 (furosemide). Blood samples for PK analysis will be collected at pre-defined timepoints for each arm throughout the study. Subjects will be on study for up to 80 days, including a 28-day screening period, 7-21 day in clinic period, and a 30-day follow up period post last dose.

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

What is the study measuring?
