Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The Intervention is a topical testosterone cream (Androforte 50mg/ml or Androfeme 10mg/ml) vs a placebo cream. All participants will be randomised at a 1:1 ratio for the application of topical testosterone vs placebo cream daily for 4 weeks. Male participants will be allocated Androforte 50mg/ml or placebo and female participants will be allocated Androfeme 10mg/ml or placebo.

Participants will be instructed to apply one (1) mL of the cream daily, at the same time each morning within a two hour window.
One (1) ml of cream is applied to the scrotum in men; and to the upper thigh, buttocks or upper torso over intact skin in women. After applying the cream, hands should be thoroughly washed. No showering, swimming or physical skin-to-skin contact with application site unless covered with clothing for 4 hours post application.

The total duration of treatment is 4 weeks. Participants will be required to keep the cream tubing to enable compliance to be checked, and all tubes will be returned to the dispensing pharmacy. To further assess compliance participants will also maintain a diary of application, and will be asked at each study contact.

At the end of the 4 weeks treatment, each participant will be offered a 4 week open label extension of testosterone treatment.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Cream will be manufactured with a matching placebo in matching tubes. The label will indicate the trial details and either treatment. The allocation label placed during manufacture will be removed by the unblinded pharmacy prior to dispensing.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A random number table will be generated by a statistician, using blocks of 4.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?

Safety/efficacy
Statistical methods / analysis
The primary measure of effect for this analysis is the treatment completion rate: the proportion of all participants randomised who achieve treatment completion. We posit that further research would be warranted if the observed treatment completion rate was 80%..

A sample size of 13 evaluable participants in the experimental group provides 90% power if the true treatment completion rate is 86%, and a 1-sided type 1-error rate of 10% if the true TC rate is 55%. The treatment completion rate will be reported with 2-sided 95% confidence intervals. The rate of completion in control patients that opt into treatment after the initial study period will also be described as will treatment duration beyond 4 weeks in the intervention arm patients.

Secondary endpoints will be summarised with mean and standard deviation to enable calculations for subsequent sample sizes. Two-sided 95% confidence intervals will be reported to enable interpretation.

Summary
Brief summary
This study is determining whether a testosterone cream is a feasible treatment for the management of fatigue in patients with advanced cancer.

Who is it for?
You may be eligible for this study if you are an adult male or female with advanced cancer, solid organ or haematopoietic malignancy. Fatigue questionnaires will also be used to evaluate suitability for this study.

Study details
Participants will be randomly assigned to apply either testosterone or placebo cream topically daily for 4 weeks. There will also be an optional extension period where all participants will be given testosterone cream for a further 4 weeks. Treatment completion will be analysed, and participants will be asked to provide blood samples and complete questionnaires on their fatigue and quality of life.

It is hoped that findings from this study will help inform researchers of the feasibility of conducting a larger study examining the impact of this testosterone treatment for advanced cancer patients.
