What is being measured

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

  1. Area Under the Plasma Concentration-Time Curve From Time Zero to Extrapolated Infinite Time (AUC[0-inf]) of Alectinib

    AUC(0-inf) is the area under the alectinib plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0-inf).

  3. Molecular Weight Adjusted Metabolite to Parent (M/P) Ratio for AUC(0-inf)

    AUC(0-inf) is the area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0-inf). AUC is a measure of the plasma concentration of the alectinib and RO5468924 (major pharmacologically active metabolite of alectinib) over time. The molecular weight adjusted M/P ratio (RO5468924/alectinib) for AUC(0-inf) is presented.

  4. Molecular Weight Adjusted Metabolite to Parent (M/P) Ratio for Cmax

    Cmax is the maximum observed plasma concentration of the alectinib and RO5468924 (major pharmacologically active metabolite of alectinib). The molecular weight adjusted M/P ratio (RO5468924/alectinib) for Cmax is presented.

    Measured: Predose (0 hour), 0.5, 1, 2, 4, 6, 8, 10, 12, 24, 36, 48, 72, and 96 hours post alectinib-dose in each intervention period

  5. Area Under the Plasma Concentration-Time Curve From Time Zero to Last Measurable Concentration (AUC[0-last]) of Alectinib and RO5468924

  6. Time to Reach Maximum Observed Plasma Concentration (Tmax) of Alectinib and RO5468924

    The Tmax is the time from alectinib administration to reach Cmax for alectinib and RO5468924 (the major pharmacologically active metabolite of alectinib).

    Measured: Predose (0 hour), 0.5, 1, 2, 4, 6, 8, 10, 12, 24, 36, 48, 72, and 96 hours post alectinib-dose in each intervention period

  7. Plasma Terminal Half-Life (t1/2) of Alectinib and RO5468924

  8. Apparent Oral Clearance (CL/F) of Alectinib

    Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.

    Measured: Predose (0 hour), 0.5, 1, 2, 4, 6, 8, 10, 12, 24, 36, 48, 72, and 96 hours post alectinib-dose in each intervention period

  9. Apparent Volume of Distribution (Vz/F) of Alectinib

    Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction of drug absorbed.

    Measured: Predose (0 hour), 0.5, 1, 2, 4, 6, 8, 10, 12, 24, 36, 48, 72, and 96 hours post alectinib-dose in each intervention period

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing RO5424802 and rifampin in people with Healthy Volunteer, run by Hoffmann-La Roche 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 10 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 21 Dec 2016. 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?

Yes. Results are posted in the registry (first posted 18 Oct 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Area Under the Plasma Concentration-Time Curve From Time Zero to Extrapolated Infinite Time (AUC[0-inf]) of Alectinib (time frame: Predose (0 hour), 0.5, 1, 2, 4, 6, 8, 10, 12, 24, 36, 48, 72, and 96 hours post alectinib-dose in each intervention period). The study lists 2 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 21 Dec 2016.
