Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Particpants will be randomly allocated to one of four treatment groups.
Group 1 will receive daily subcutaneous (s/c) injections of saline (placebo) for 4 days.
Group 2 will receive daily s/c injections of superactive GnRH analog (Lucrin 1mg) for 4 days.
Group 3 will receive daily s/c injections of Lucrin 1mg for 4 days and concurrent administration of 100mg injectable testosterone (T) esters to supress endogenous leutenising hormone (LH) and T production.
Group 4 will receive daily s/c injections of Lucrin 1mg for 4 days and concurrent administration of nandrolone decanoate 100mg to supress endogenous LH and T production.
Blood and urine samples will be collected from all particpants at intervals from 0 for up to 14 days.

Treatment: Drugs
Comparator / control treatment
Group 1 (placebo group) will receive s/c saline injection in place of s/c Lucrin.
All particpants will provide baseline blood and urine samples to measure against post treatment samples.

Placebo

Outcomes
Primary outcome [1] 5705 0
To determine the hormonal effects of a supercative GnRH analog on the hormonal markers used in sports doping ie serum and urine LH and testosterone, and on the urinary testosterone/epitestosterone (T/E) ratio.
Timepoint [1] 5705 0
Samples of blood and urine will be collected at baseline and daily for up to 14 days.
Secondary outcome [1] 241620 0
To develop a detection test for this GnRH analog to be used in sports doping laboratories.
Timepoint [1] 241620 0
GnRH analog detection test will be developed following the collection of all study samples.

Summary
Brief summary
Sports anti-doping study. The aim of this study is to see what effects on testosterone an injection of a synthetic hormone called GnRH analog has. GnRH analogs are banned in elite sports as they are considered to enhance an athletes performance by increasing the bodies production of testosterone. In this study blood and urine specimens will be collected from healthy male volunteers who have been given several injections a GnRH analog. Some of the volunteers will also be given an injection of testosterone or a drug called nandrolone. These three drugs are all banned in elite athletes, but it is thought that they may be being used in combination illicitly.
Some of the volunteers will recieve injections of saline only given as a placebo, this allows us to compare the results with those of the volunteers receiving the drugs.
The blood and urine samples taken from the volunteers (before and after the injections) will be analysed to see what effects they have on hormone levels, and will be used to help develop a test to detect the use of GnRH anaolgs by elite athletes.
