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

Measured: Days 1 and 8 (16 plasma samples obtained from time zero to 48 hours post dose)
PK of metformin in plasma: AUC from the time of dosing to infinity (AUCinf)
Measured: Days 1 and 8 (16 plasma samples obtained from time zero to 48 hours post dose)
PK of metformin in plasma: Maximum Concentration (Cmax)
Measured: Days 1 and 8 (16 plasma samples obtained from time zero to 48 hours post dose)
Secondary outcomes (3)
PK variable for isavuconazole in plasma: Trough Concentration (Ctrough)
Measured: Days 6, 9 and 10 (1 sample prior to isavuconazole dosing)
Composite of PK variables for isavuconazole in plasma: AUCtau, Cmax and tmax
AUC during the time interval between consecutive dosing (AUCtau); the time after dosing when Cmax occurs (tmax)
Measured: Days 7 and 8 (13 samples collected per day)
Composite of PK variables for metformin in plasma: t1/2, tmax, CL/F and Vz/F

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing isavuconazole and metformin in people with Pharmacokinetics of Isavuconazole and Pharmacokinetics of Metformin, 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 9 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 24 Jun 2013. 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?
Pharmacokinetics (PK) of metformin in plasma: Area Under the Concentration-Time Curve (AUC) from the time of dosing to the last quantifiable concentration (AUClast) (time frame: Days 1 and 8 (16 plasma samples obtained from time zero to 48 hours post dose)). The study lists 3 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 24 Jun 2013.
