Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Application of active treatment, 1% testosterone cream, 0.5ml (10mg/ml), or placebo cream
applied transdermally daily to upper thigh or lower torso by participant for 12 months.

Dosing may be modified by an appointed independent Study Safety Monitor (a clinician experienced in T therapy for women) who will have access to the randomisation code and will review each participant’s 12 and 26-week T level (measured locally). For any woman with a T level 1.5 times the upper limit of the premenopausal range for each site’s T assay, the Safety Monitor will request both the participant with high T, as well as a randomly selected participant from the same study site on placebo with a recent blood draw, decrease the amount of T cream applied (by 25%) and both to have repeat blood levels after 3 weeks. This ensures dose adjustment without unblinding.
Compliance will be assessed by collection and weighing of returned cream containers at week 12, week 26 and week 52 after commencement of 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)
Allocation is concealed by central randomisation by computer
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization codes will be computer generated and participants will be randomly allocated to treatment with T or identical placebo in a 1:1 ratio. There will be 3 collaborating centres with approximately 38 women recruited per centre. Two separate randomisation schedules will be generated for each centre, one for women on oral estrogen and the other for women using transdermal ERT as these two modes of estrogen administration have different effects on the protein binding of T.

Efficacy
Statistical methods / analysis
The analysis will be by intention-to-treat with all women who were randomised and received at least one dose of study medication included. For women who do not complete the study, data collected at 6 months or at their exit visit will be used (last observation carried forward). The primary outcome variable (% change in BMD adjusted for baseline differences) will be analysed appropriately depending on the normality of the distribution of the data, using either astudent’s t-test for independent means or the Wilcoxon rank sum test. Other outcome variables will be analysed as change in the relevant parameter +/- adjustment for baseline differences between groups, with biochemical data likely to be transformed prior to analysis.

Summary
Brief summary
The purpose of this research is to determine whether the use of a topical testosterone cream prevents bone loss and improves sexual function in women with premature ovarian insufficiency (POI) and early menopause who are taking a standard dose of estrogen.
We hypothesize that 0.5ml of testosterone cream, versus placebo, applied daily for 12 months will result in a clinical improvement in total hip bone mineral density in these women, and other markers of musculoskeletal health, as well as improvements in sexual function and reduced sexually associated personal distress.


The purpose of this research is to determine whether the use of transdermal testosterone therapy, in a dose shown restores testosterone levels to those of premenopausal women, prevents bone loss and improves sexual function in women with POI who are taking the standard dose of estrogen.
