About this study
Official title: A 3-Part, Open-Label Study to Assess Pharmacokinetic Drug-Drug Interaction Between Avatrombopag When Co-Administered With Fluconazole (Moderate Inhibitor of CYP2C9 and CYP3A), Itraconazole (Strong CYP3A Inhibitor), or Rifampin (Strong CYP3A and Moderate CYP2C9 Inducer) in Healthy Subjects
The purpose of this study is to determine the effects of concomitant administration with fluconazole, itraconazole, and rifampin on the pharmacokinetics (PK) of a single 20-mg dose of avatrombopag in healthy participants.
Read the detailed description
This study will be a single center, open-label, drug-drug interaction study in healthy participants. The study will consist of 3 parts: In Part A, the effects of steady-state dosing of a moderate inhibitor of CYP2C9 and CYP3A (fluconazole) on the single-dose PK of avatrombopag will be assessed. In Part B, the effects of steady-state dosing of a strong CYP3A inhibitor (itraconazole) on the single-dose PK of avatrombopag will be assessed. In Part C, the effects of steady-state dosing of a strong CYP3A and moderate CYP2C9 inducer (rifampin) on the single-dose PK of avatrombopag will be assessed.
Each Part of the study will consist of 2 phases: Pretreatment and Treatment. The Pretreatment Phase will consist of 2 periods: Screening and Baseline Period 1.The Treatment Phase will consist of 2 treatment periods: Treatment Period 1 (administration of a single oral dose of avatrombopag 20 mg alone under fed conditions); and Treatment Period 2 (administration of oral doses of each inhibitor or inducer alone and concomitant administration of a single oral dose of avatrombopag 20 mg with each inhibitor or inducer [fluconazole in Part A, itraconazole in Part B, or rifampin in Part C] under fed conditions).

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The purpose of this study is to determine the effects of concomitant administration with fluconazole, itraconazole, and rifampin on the pharmacokinetics (PK) of a single 20-mg dose of avatrombopag in healthy participants.
Detailed description
This study will be a single center, open-label, drug-drug interaction study in healthy participants. The study will consist of 3 parts: In Part A, the effects of steady-state dosing of a moderate inhibitor of CYP2C9 and CYP3A (fluconazole) on the single-dose PK of avatrombopag will be assessed. In Part B, the effects of steady-state dosing of a strong CYP3A inhibitor (itraconazole) on the single-dose PK of avatrombopag will be assessed. In Part C, the effects of steady-state dosing of a strong CYP3A and moderate CYP2C9 inducer (rifampin) on the single-dose PK of avatrombopag will be assessed.
Each Part of the study will consist of 2 phases: Pretreatment and Treatment. The Pretreatment Phase will consist of 2 periods: Screening and Baseline Period 1.The Treatment Phase will consist of 2 treatment periods: Treatment Period 1 (administration of a single oral dose of avatrombopag 20 mg alone under fed conditions); and Treatment Period 2 (administration of oral doses of each inhibitor or inducer alone and concomitant administration of a single oral dose of avatrombopag 20 mg with each inhibitor or inducer [fluconazole in Part A, itraconazole in Part B, or rifampin in Part C] under fed conditions).

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 9 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Mean maximum observed concentration (Cmax) (time frame: Predose of Day 1 (Treatment Period 1), Predose of Day 7 (Treatment Period 2), and 1, 2, 3, 4, 5, 6, 7, 8, 12, 24, 48, 72, 96, 144, and 216 hours postdose of avatromobag for Treatment period 1 and 2). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Mar 2017.
