  • Subjects with intolerance or adverse reactions to ethanol.
  • History or clinical evidence of alcoholism, drug abuse, or regular use of psychoactive drugs.
  • History or clinical evidence of cardiovascular, respiratory, renal, hepatic, endocrine, gastrointestinal, hematological, neurological, dermatological or other acute or chronic diseases that, in the opinion of the Principal Investigator or the collaborators designated by it, may pose a risk to the subjects or interfere with the objectives of the study.

About this study

Official title: Steroid Profile: Differentiating Testosterone Administration From (Simultaneous) Ethanol Consumption: Evaluation of Newly Developed Markers

Background:

Testosterone is an anabolic steroid widely known to improve physical performance. Its consumption is banned by the World Anti-Doping Agency (WADA). The steroid profile is one of the components of the Athlete's Biological Passport (ABP), which consists of selected biological variables that indirectly reveal the effects of doping. Alcohol consumption has been proved to alter the steroid profile and this may lead to the use of ethanol as a masking agent for testosterone administration.

Hypothesis:

Ratios of different testosterone biomarkers vary after ethanol administration: [6-hydroxy-androsterone-3-glucuronide (6OH-Andros3G) / epitestosterone-glucuronide (EG)] and [6-hydroxy-etiocholanolone-3-glucuronide (6OH-Etio3G) / EG] decrease, while [testosterone-glucuronide (TG) / EG] increases.

Primary objective:

To evaluate if the combination of the markers TG, EG, 6OH-Andros3G and 6OH-Etio3G, as well as ethyl glucuronide (EtG) and ethyl sulfate (EtS), can be routinely used to differentiate between changes in the steroid profile due exclusively to the consumption of alcohol and those produced when alcohol is consumed during a testosterone administration.

Secondary objectives:

  1. To explore the potential of the simultaneous determination of both phase I and phase II metabolites in alternative matrices (plasma from blood samples collected as for the haematological module of ABP, or saliva) in the screening of testosterone misuse.
  2. To look for the differences into a comprehensive steroid profile (determined in urine, plasma and saliva) between samples collected after testosterone administration and after the combination of testosterone and ethanol.

Methods:

Phase I, single-blind, crossover-design clinical trial, placebo controlled, with 4 conditions randomly assigned in male healthy caucasian subjects with a wash-out period between treatments.

Being tested
Testosterone gel, Ethanol Solution, Testosterone placebo (vaseline), Ethanol placebo (lemon-flavoured water)
Keywords

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Testosterone gel and Ethanol Solution in people with Healthy Volunteers, run by Parc de Salut Mar at 1 site in Spain.

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 8 inclusion and 20 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 18 Nov 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 Spain. 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. Some participants in this study may receive a placebo. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Change in steroid profile in urine (time frame: From baseline (pre-administration) to 48 hours after last administration (fractions: 0-2, 2-4, 4-6, 6-8, 8-24 hours each day, and 24-48 hours post-administration last day)). The study lists 5 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 18 Nov 2019.
