About this study

Official title: A Phase 1, Open-Label, Sequential Study of the Effect of Multiple Doses of Isavuconazole on the Pharmacokinetics of a Single Dose of Dextromethorphan in Healthy Adult Subjects

The purpose of this study is to assess the effect of multiple doses of isavuconazole on the pharmacokinetics of a single dose of dextromethorphan in healthy adult subjects.

Read the detailed description

Subjects will check-in on Day -1 and remain confined to the clinical unit until Day 13. On the morning of Day 1, subjects will receive a single dose of dextromethorphan. On Days 6 and 7, subjects will receive isavuconazole three times daily (TID) administered approximately 8 hours apart. On Day 8 through 12, subjects will receive isavuconazole once daily (QD). On Day 10, subjects will receive a single dose of dextromethorphan. A follow-up visit will be scheduled on Day 21 (± 2 days).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pharmacokinetic (PK) profile for dextromethorphan (in plasma): AUCinf, Cmax , AUClast

    Area under the concentration-time curve (AUC) from time 0 extrapolated to infinity (AUCinf), maximum concentration (Cmax), and AUC from time of dosing to the last quantifiable concentration (AUClast).

    Measured: Pre-dose on Days 1 and 10, and at 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 12, 16, 20, 24, 48 and 72 hours post-dose

Secondary outcomes (5)
  1. PK profile for dextromethorphan (in plasma): t1/2, tmax, CL/F, and Vz/F

    Apparent terminal elimination half-life (t1/2), time to attain Cmax (tmax), apparent body clearance after oral dosing (CL/F), and apparent volume of distribution (Vz/F)

    Measured: Pre-dose on Days 1 and 10, and at 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 12, 16, 20, 24, 48 and 72 hours post-dose

  2. PK profile for dextrorphan (in plasma): AUClast, AUCinf, Cmax, tmax, t1/2

    Measured: Pre-dose on Days 1 and 10, and at 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 12, 16, 20, 24, 48 and 72 hours post-dose

  3. PK Isavuconazole (in plasma): trough concentration (Ctrough)

    Measured: Pre-dose on Days 8 and 12 and at 24 (Day 13) hours post-dose

  4. PK profile for Isavuconazole (in plasma): AUCtau, Cmax, and tmax

    AUC during time interval between consecutive dosing (AUCtau)

    Measured: Day 9 pre-dose and at 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 12,16, 20 hours post-dose and Day 10 pre-dose and at 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 12, 16, 20, and 24 (Day 11) hours post-dose

  5. Safety assessed by recording of adverse events, clinical laboratory evaluation, electrocardiograms (ECGs) and vital signs

    Measured: Day 1 through Day 13

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Isavuconazole and dextromethorphan in people with Pharmacokinetics of Isavuconazole and Pharmacokinetics of Dextromethorphan, run by Astellas Pharma Global Development, Inc. at 1 site in United States.

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 5 inclusion and 13 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 23 Feb 2015. 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?

Pharmacokinetic (PK) profile for dextromethorphan (in plasma): AUCinf, Cmax , AUClast (time frame: Pre-dose on Days 1 and 10, and at 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 12, 16, 20, 24, 48 and 72 hours post-dose). 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 23 Feb 2015.
