Had to agree to use an accepted method of contraception (i.e., spermicide and barrier methods or spermicide and non-hormonal intrauterine contraceptive device). The subject had to agree to continue with the same method throughout the study. Hormonal contraceptives were not allowed.
females not of childbearing potential could also have been included if they had no menstrual period for one year and were considered as post-menopausal.

About this study

Official title: A Randomized, Two-way Crossover Study to Compare the Bioavailability of 300 mg Trazodone Hydrochloride Extended-release Caplets (Containing Contramid®) (Administered Once Daily) and 100 mg Trazodone Hydrochloride Immediate-release Tablets (Administered Three Times Daily) at Steady State

The purpose of this study was to compare the pharmacokinetic profiles at steady state of the test product, 300 mg trazodone hydrochloride (HCl) extended-release caplets (containing Contramid®), when administered once daily, and the reference product, 100 mg trazodone HCl immediate-release tablets (Apotex Corp.), when administered three times daily, for one week. For this purpose, the rate and extent of absorption of trazodone and formation of m-chlorophenylpiperazine (mCPP) after administration of multiple doses of up to 300 mg of each of the two formulations was compared.

Conditions: Healthy Subjects, Bioavailability, Pharmacokinetics

What is being measured

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

Bioequivalence Based on Cmax,ss
Cmax,ss = Maximum plasma concentration (Cmax) at steady state (ss): (Cmax,ss). Measured in nanograms per milliliter (ng/mL).
Measured: 9 days
Bioequivalence Based on AUCss
AUCss = Area under the plasma concentration curve (AUC) vs. time data pairs at steady state (ss): AUCss.
Measured in nanograms x hours per milliliter (ng*h/mL).
Measured: 9 days

Secondary outcomes (5)

Minimum Plasma Concentration (Cmin,ss)
Minimum plasma concentration at steady state (Cmin,ss). Measured in nanograms per milliliter (ng/mL)
Measured: 9 days
Plasma Concentration at 24 Hours Post-evening Dose (C24h)
Plasma concentration at 24 hours post-evening dose (C24h) in nanograms per milliliter (ng/mL)
Measured: 9 days
Time to Peak Exposure (Tmax)
Time to peak exposure (Tmax) at steady state.
Measured: 9 days
Percentage Swing
Percentage swing is a pharmacokinetic parameter calculated as follows:
((Cmax,ss - Cmin,ss)/Cmin,ss)*100.
Where:
Cmax,ss = Maximum concentration at steady state; Cmin,ss = Minimum concentration at steady state.
It was calculated over 24 hours on day 9.
Measured: 9 days
Percentage Peak-Trough Fluctuation (%PTF)
Percentage Peak-Trough Fluctuation (%PTF) of trazodone calculated as [100*(Cmax-Cmin)/Cav].
Cmax: Maximum plasma concentration Cmin: Minimum plasma concentration Cav: Average plasma concentration
Measured: 9 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Trazodone HCl in people with Healthy Subjects and Bioavailability, run by Labopharm Inc..

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 14 inclusion and 19 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 30 Apr 2012. Status can change between updates, so confirm with the study contact before making plans.

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 16 Aug 2010). 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?

Bioequivalence Based on Cmax,ss (time frame: 9 days). 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 NCT01121926.

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 30 Apr 2012.
