What is being measured

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

  1. Area Under the Curve From Time Zero to Extrapolated Infinite Time (AUC Infinity)

    AUCinf = Area under the plasma concentration-time curve from time 0 (predose) extrapolated to infinite time; measured in nanograms times hour per milliliter (ng*hr/mL). Pharmacokinetic (PK) parameters derived from subject's concentration data; collected Period 1, Day 1 to Day 4; Period 2, Day 1 to Day 4.

    Measured: 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 9, 10, 12, 24, 36, 48, 72 hours post dose

  2. Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast)

    AUClast = area under the plasma concentration-time curve from 0 (predose) to the time of the last measureable concentration (Clast). PK parameters derived from subject's concentration data; collected Period 1, Day 1 to Day 4; Period 2, Day 1 to Day 4.

    Measured: 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 9, 10, 12, 24, 36, 48, 72 hours post dose

  3. Maximum Observed Plasma Concentration (Cmax)

    Cmax = maximum observed plasma concentration. Measured in nanograms per milliter (ng/mL); collected Period 1, Day 1 to Day 4; Period 2, Day 1 to Day 4.

    Measured: 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 9, 10, 12, 24, 36, 48, 72 hours post dose

Secondary outcomes (2)
  1. Time to Reach Maximum Plasma Concentration (Tmax)

    Tmax = time (hours) to maximum plasma concentration (Cmax). Observed directly from data as time of first occurrence; PK parameters derived from subject's concentration data; collected Period 1, Day 1 to Day 4; Period 2, Day 1 to Day 4.

    Measured: 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 9, 10, 12, 24, 36, 48, 72 hours post dose

  2. Plasma Elimination Half-life (t1/2)

    t1/2 = terminal elimination half-life in hours; ln 2/kel, where kel is the termination phase rate constant calculated by a linear regression of the log-linear concentration-time curve. Only those data points judged to describe the terminal log-linear decline were used in the regression. PK parameters derived from subject's concentration data; collected Period 1, Day 1 to Day 4; Period 2, Day 1 to Day 4.

    Measured: 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 9, 10, 12, 24, 36, 48, 72 hours post dose

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Atorvastatin in people with Hypercholesterolemia, run by Pfizer's Upjohn has merged with Mylan to form Viatris 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 2 inclusion and 2 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 Feb 2021. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 15 Oct 2009). 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 Curve From Time Zero to Extrapolated Infinite Time (AUC Infinity) (time frame: 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 9, 10, 12, 24, 36, 48, 72 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 21 Feb 2021.
