Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Arm 1 - Spironolactone
25mg oral capsule twice daily for first week, then 50mg oral capsule twice daily for next 15 weeks.

Arm 2 - Tenofovir Alafenamide (TAF)

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Yes - allocation concealed by central randomisation via the study statistician, whom is off-site and will be contacted for the allocation schedule.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Permuted block randomisation and minimisation, Factors considered will be age, level of disability, treatment (no/low efficacy versus high efficacy disease modifying therapy) and recruiting site.
Masking / blinding

Efficacy
Statistical methods / analysis
A sample of 80 subjects per arm has 90% power to detect a minimum median difference of 0.81 of a FSS point from a pre-intervention baseline of FSS=543 and a minimum difference of 13.6 points on the MFIS scale from a pre-intervention baseline of MFIS=509, both at the 5% significance level. A 10% loss to follow-up or sample attrition is anticipated. These calculations are based on a previous study which showed that the minimum change in fatigue scores in those with MS that is clinically meaningful is 0.45 points for the FSS and 4 points for the MFIS.

For all outcomes, an intention to treat analysis will be conducted by the study statistician who will not be blinded to the treatment allocations. The continuous primary and secondary outcome data will be analysed using mixed model, hierarchical linear modelling, nested within treatment groups, taking time as a within-subjects effect and grouped as a between-subject effect. This includes adjusting for non-MS related factors that may cause fatigue such as sleep quality and exercise.

Summary
Brief summary
Existing Multiple Sclerosis (MS) therapies are effective at reducing MS relapses but there is currently no effective therapy for treating MS related fatigue. There is an understanding that chronic Epstein Barr Virus (EBV) infection of immune cells, called B lymphocytes, might be a driver of chronic symptoms in MS, such as fatigue. As such, this trial examines whether treating EBV infection can improve MS-related fatigue. The study tests two 'repurposed' anti-viral drugs, 'Tenofovir alafenamide' and 'Spironolactone', as an add-on to standard MS treatment for 16 weeks to see if fatigue can improve in participants with relapsing MS. We hypothesise that both Tenofovir alafenamide and Spironolactone will improve measures of fatigue in participants with relapsing MS compared to placebo.
