Description of intervention(s) / exposure
Nine oral capsules containing a combination of:
1. N-Acetyl-cysteine (1000mg),
2. Acetyl L Carnitine (1000mg),
3. CoenzymeQ10 (600mg),
4. alpha lipoic acid (800mg),
5. combination capsule containing: Ascorbic acid (250mg), d-alpha-Tocopherol (equiv. vitamin E) 33.3 mg (52 IU), Thiamine nitrate (25 mg), Riboflavin (vitamin B2; 20 mg), Nicotinamide (vitamin B3; 20 mg), Biotin (vitamin H; 100 mg), Folinic acid (vitamin B9, 400 mcg)
Capsule 1-4 will be consumed twice a day, morning and evening Capsule 5 will only be consumed in the morning.
Capsules will be taken at the same time. These will be consumed each day for 16 weeks.

The study coordinator or site-specific research staff will make phone/in person contact at 2, 4, 8, and 12 weeks post-baseline to ensure adverse events and any relapses are captured, to review concomitant medications, and to promote participant adherence to the intervention.
If the participant experiences a serious adverse event (SAE) that is suspected to be linked to the study medication or compromises the participant’s ability to adhere to the intervention, the intervention will be ceased; however, the participant will remain in the trial and will be followed-up through to the end of the study.

Outcomes
Primary outcome [1] 319771 0
We will use the Fatigue Severity Scale (FSS), and the Modified Fatigue Impact Scale (MFIS) as the primary measure. Both the FSS and the MFIS are sensitive to changes in fatigue due to disease progression. The FSS measures functional outcomes of fatigue and has been shown to have high sensitivity and internal consistency (Cronbach’s alpha 0.88 and 0.89 respectively). The FSS is comprised of 9 items, each scored from 1-7 on a Likert scale, where 1 signifies no symptoms of fatigue and 7 indicates severe fatigue. The MFIS is a 21-item measure that has valid and reliable separate domains for physical, cognitive and psychosocial fatigue.

Targeted metabolomic plasma analyses of four metabolites within the kynurenine pathway (tryptophan, kynurenine, kynurenic acid, and quinolinic acid) will be undertaken with high performance liquid chromatography mass spectrometry. Non-targeted metabolomic analyses of plasma will be performed using the gas chromatography time-of-flight mass spectrometry - 144 major metabolic compounds from various biological pathways, including the kynurenine pathway, are selected for metabolomics analysis. Urine samples will also be collected for metabolomic analyses.

Microbiome profile
Microbiome analyses: The V4 region of the 16S rRNA gene will be sequenced at the Australian Genome Research Facility (AGRF) using the Illumina MiSeq platform (microbiome composition analysis). The SILVA reference database will be used to establish phylogenetic structure of the gastrointestinal microbiome communities. Bioinformatic analysis will be conducted using QIIME2 and Phyloseq software to establish a number of metrics regarding the microbiome. These include alpha and beta-diversity as well as relative abundance differences across all taxonomic levels specifically, Akkermansia muciniphila, Acinetobacter calcoaceticus, and Parabacteroides distasonis. If the analyses does not produce clear results for these taxa, we will employ PCR analysis for individual taxa of interest

Magnetic Resonance Spectroscopic Imaging (MRSI) is an important imaging tool that combines imaging and spectroscopic characteristics. MRSI allows clinical imaging researchers to characterize brain diseases: neurologically as well as metabolically. Magnetic Resonance Spectroscopy (MRS) is the only technique available that can characterize the metabolic tissue state. To study neurochemical -status of Relapsing Remitting Multiple Sclerosis (RRMS) patients, all MR studies will be conducted on a 3T Siemens Clinical Research Scanner (Prisma) located at HMRI using a 64 channel head and neck coil to determine the difference between MS patients with oral supplement compared to MS patients on placebo.

MRSI will be conducted at baseline and Week-16 at John Hunter Hospital, Newcastle, NSW site only

Efficacy
Statistical methods / analysis
The RCT of n=150 (n=75 per arm) has been designed to detect a moderate reduction in fatigue. The trial has been powered to have 95% power to detect fatigue reduction in the order of 15% as this magnitude will still be of clinical significance.

Statistical analysis: For all outcomes, an intent to treat analysis will be conducted. Because of the study design advantage of serial longitudinal measures, we will use multi-level models to account for the correlation between outcomes measured repeatedly on the same participant. 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 and group as a between subjects effect. We will evaluate differing distributions between the two arms in baseline or post-randomisation confounders and adjust as required using multivariable models. This includes adjusting for non-MS related factors that may cause fatigue such as sleep quality and exercise.

Metabolomic analyses: To discover changes in plasma metabolites due to CMA treatment, and infer the involvement of specific metabolic pathways, we will compare the metabolic measurements from individuals between the two arms of the trial. We will apply the latest techniques for analysing metabolomic data, such as partial least squares-based methods, as well as explore the use of other multivariate classification methods. These will include considering metabolites individually as well as grouped by their known biological pathways (pathway analyses). As a secondary aim, we will build a predictive model of individuals’ response to treatment based on their baseline variables (metabolomic and other), to determine whether such a model would be clinically useful for targeting mitochondrial treatment.

Genomic analyses: we will use a range of genomic network approaches including the GLMNet approach. Briefly, GLMNet fits a generalized linear model via penalized maximum likelihood and is akin to a step-wise forward regression with the added feature of being able to perform internal cross-validation. GLMNet allows for rapid discovery of panels of related genomic sites likely to be associated with outcome. Follow-up analyses using standard GLM methods will be performed to factor in other factors as covariates.
