Testogel® (Testosterone Gel 50mg/5g) in the Treatment of Male Hypogonadism

February 6, 2013 updated by: Laboratoires Besins International

A Multi-center, Double Blind, Randomized, Placebo Controlled Study of Testogel® (Testosterone Gel 50mg/5g) in the Treatment of Male Hypogonadism

The purpose of this study is to evaluate the safety and efficacy of Testogel® 50mg/5g gel administered once daily (QD, morning dosing) compared to placebo administered once daily (QD, morning dosing), for 3 months, in hypogonadal men with testosterone deficiency being confirmed by clinical features and biochemical tests. For men with hypogonadism, treatment aims to restore testosterone levels to normal physiological range.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 64 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Percentage of patients with morning serum Total Testosterone concentration within the physiological range (300 - 1000 ng/dL or 10.4 - 34.7 nmol/L) after 3 months of Testogel treatment compared to placebo-treatment
Time Frame: 3 months
3 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
morning serum Total Testosterone (TT) concentration compared to placebo treatment
Time Frame: 3 months

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.
