Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Participants With at Least One Treatment-related Adverse Event
Time Frame: 16 weeks
|
Safety and tolerability will be assessed based on treatment-related adverse events in the two arms.
|
16 weeks
|
Number of Total Treatment-related Adverse Events
Time Frame: 16 weeks
|
Safety and tolerability will be assessed based on treatment-related adverse events in the two arms.
|
16 weeks
|
Incidence of Treatment-related Adverse Events (AE)
Time Frame: 16 weeks
|
Safety and tolerability will be assessed based on treatment-related adverse events in the two arms.
AE incidence will be measured as total number of events per 1000 exposure years.
|
16 weeks
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Fasting Bile Acid Levels in Plasma
Time Frame: Baseline to 16 weeks
|
The change of targeted bile acid levels over the course of 16 weeks (duration of the study) is reported. Bile acid levels (ng/mL) were log transformed before analysis to approximate normal distribution. Units are log(levels) per 16 weeks. Values are derived from linear mixed-effects models. |
Baseline to 16 weeks
|
Change in Microbiome Alpha-diversity Measured by Shannon Index at the End of the Study
Time Frame: Baseline to 16 weeks
|
Change in Shannon index of the gut microbiota between baseline and end of study (16 weeks).
Shot-gun metagenomic sequencing in first morning stool specimen was utilized to derive the microbiome composition.
Higher values of the index indicate more diversity in the microbial community.
The minimum value the Shannon index can take is 0 (no diversity).
There is no upper limit to the index.
|
Baseline to 16 weeks
|
Change in Flow Cytometric Assessments of Peripheral Blood Mononuclear Cells (PBMCs)
Time Frame: Baseline to 16 weeks
|
Change in flow cytometric assessments over the course of 16 weeks (duration of the study). Cells are expressed as ratios of their parent types. Units reported as change in the ratio per 16 weeks. Values are derived from linear mixed-effects models. |
Baseline to 16 weeks
|
Change in Quality of Life Based on Multiple Sclerosis Quality of Life (MSQOL)-54 Instrument
Time Frame: Baseline to 16 weeks
|
Change in physical and mental health scores as assessed using the Multiple Sclerosis Quality of Life-54 (MSQOL-54) instrument over the course of 16 weeks (duration of the study).
This 54-item instrument generates 12 subscales along with two summary scores, and two additional single-item measures.
Two summary scores - physical health and mental health - are derived from a weighted combination of scale scores.
Higher scores suggest a better quality of life.
Scores can range from 0 to 100.
