Study groups in NCT02233751
Study group	Role	What they receive
Testosterone enanthate auto-injector - 50 mg	Experimental	Testosterone enanthate auto-injector - 50 mg (SC injection) Receives: Combination Product: Testosterone enanthate auto-injector

What is being measured

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

Maximum Concentration (Cmax) for Serum Testosterone and Testosterone Enanthate
Cmax = Maximum blood concentration (ng/dL) of TT=Total Testosterone and TE=Testosterone Enanthate
Measured: Maximum serum concentrations occurring during an 8 days study window
Area Under the Concentration-time Curve From Time Zero to Time t
AUC(0-168h) (ng⋅hr/dL) = area under the concentration-time curve from time zero to Day 8 (1 week);
Measured: 168 hrs
Area Under the Concentration-time Curve From Time Zero to Infinity
AUC(0-inf) (ng⋅hr/dL) = area under the concentration-time curve from time zero to infinity
Measured: time zero to infinity

Secondary outcomes (4)

Time to Maximum Concentration (Tmax)(hr)
tmax = Time to reach maximum concentration
Measured: The sample time of Cmax during a 168 hour sampling interval
Half-life (t 1/2)(hr)
t 1/2 = Half-life is the time required for a concentration to reduce to half its initial value
Measured: 168 hours
Clearance CL/F (L/hr)
Clearance - volume of plasma from which TT/TE is completely removed per unit time
Measured: 168 hours
Vd/F (L)
Vd/F (L) = Apparent volume of distribution
Measured: 168 hours

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Testosterone enanthate auto-injector in people with Hypogonadism, run by Antares Pharma 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 4 inclusion and 13 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 19 Apr 2019. 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 19 Apr 2019). 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?

Maximum Concentration (Cmax) for Serum Testosterone and Testosterone Enanthate (time frame: Maximum serum concentrations occurring during an 8 days study window). 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?

On the ClinicalTrials.gov record for NCT02233751.

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 19 Apr 2019.
