Study group	Role	What they receive
Cohort 1	Experimental	24 subjects (12 subjects per sequence) will receive treatment A) one 5 mg amlodipine 3rd OD tablet (test) with water and treatment B) one 5 mg amlodipine 2nd OD tablet (reference) with water. Receives: Drug: Amlodipine

What is being measured

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

Area Under the Concentration-Time Curve From Zero Time Until the Last Sampling Time (AUCt)
Area under the concentration-time curve from zero time until the last sampling time
Measured: prior to dosing, 2, 4, 6, 8, 10, 12, 16, 24, 48, 72, 96, 120 and 144 hours post dose
Maximum Observed Plasma Concentration (Cmax)
Measured: prior to dosing, 2, 4, 6, 8, 10, 12, 16, 24, 48, 72, 96, 120 and 144 hours post dose

Secondary outcomes (5)

Area Under the Plasma Concentration-Time Curve From Time Zero to Last Quantifiable Concentration (AUClast), Area Under the Plasma Concentration-Time Curve to Infinity (AUCinf)
AUC last = Area under the concentration versus time curve from zero time until the last measurable concentration is calculated using the trapezoidal rule.
AUCinf = AUClast + (Ct / kel), where Ct is the estimated concentration at the last measurable concentration.
Measured: prior to dosing, 2, 4, 6, 8, 10, 12, 16, 24, 48, 72, 96, 120 and 144 hours post dose
Apparent Terminal Elimination Phase Rate Constant (Kel)
Estimated as the absolute value of the slope of a linear regression during the terminal phase of the natural-logarithm (ln) transformed concentration-time profile.
Measured: prior to dosing, 2, 4, 6, 8, 10, 12, 16, 24, 48, 72, 96, 120 and 144 hours post dose
Apparent Terminal Elimination Half-Life (T-half)
Terminal phase half-life calculated as ln(2) / kel
Measured: prior to dosing, 2, 4, 6, 8, 10, 12, 16, 24, 48, 72, 96, 120 and 144 hours post dose
Mean Residence Time (MRT)
MRT = AUMCinf / AUCinf, where AUMCinf is the area under the first moment curve from zero time to infinity calculated as AUMCinf = AUMCt + ((t x Ct) / kel) + (Ct / kel^2). AUMCt is the area under the first moment curve from zero time to time t calculated using the trapezoidal method.
Measured: prior to dosing, 2, 4, 6, 8, 10, 12, 16, 24, 48, 72, 96, 120 and 144 hours post dose
Time to Reach Maximum Observed Plasma Concentration (Tmax)
Measured: prior to dosing, 2, 4, 6, 8, 10, 12, 16, 24, 48, 72, 96, 120 and 144 hours post dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Amlodipine in people with Healthy, run by Pfizer's Upjohn has merged with Mylan to form Viatris Inc. at 1 site in Japan.

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 3 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 28 Jan 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 Japan. 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 4 Jan 2012). 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 Concentration-Time Curve From Zero Time Until the Last Sampling Time (AUCt) (time frame: prior to dosing, 2, 4, 6, 8, 10, 12, 16, 24, 48, 72, 96, 120 and 144 hours post dose). 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?

On the ClinicalTrials.gov record for NCT01004614.

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 28 Jan 2021.
