Change in Inclusion Body Myositis Functional Rating Scale (IBMFRS) Total Score
Measured by rate of decline in the IBMFRS between experimental and placebo groups. The IBMFRS is a 10-item questionnaire. Scores for each item range from 0 to 4. There is a total maximum score of 40 and minimum score of 0. The higher the score the better functional status of the person.
Time frame: Change from Baseline to Month 20

Time frame: Change from Baseline to Month 12
Grip Strength
Unilateral hand grip strength in both hands measured using the Jamar Dynamometer. Results are for the stronger limb, as identified at baseline.
Time frame: Change from Baseline to Month 12 and 20
Modified Timed up and go (mTUG)
The patient's combined ability to rise from a chair and walk 3 meters, turn around and walk back to the chair and sit down. The test was performed twice and the fastest time was used. The results were expressed as velocity in meters/second.
Time frame: Change from Baseline to Month 12 and Month 20
Manual Muscle Testing (MMT), Total Score
The Manual Muscle Testing (MMT) scores the strength of 24 muscles (axial, proximal, and distal muscles, tested bilaterally) on a scale from 0 to 10 points. The total score is calculated as an average across the 24 muscles and ranges from 0 to 10. The total score will increase if a patient is getting stronger and decrease if a patient is getting weaker.

6 Minute Walk Test (6MWT); Distance After 6 Minutes (6MWD)
The distance patients could walk in 6 minutes. The distance walked in meters was recorded after 6 minutes.
Time frame: Change from Baseline to Month 12 and Month 20
Short Form-36 (SF-36) Physical Component Score
Measured using the Short Form health survey with 36 items (SF-36). The questionnaire measures 8 health concepts which yields 2 summary measures: physical and mental health. The physical component score includes 4 scales of physical functioning (10 items), role limitations due to physical health (4 items), bodily pain (2 items), and general health (5 items). To score the SF-36, scales are standardized with a scoring algorithm to obtain a score ranging from 0 to 100, and the summary measure is calculated as the average score. Higher scores indicate better health status.

Maximum Voluntary Isometric Contraction (MVICT) of Quadriceps
Unilateral strength of the knee extensor muscles on both limbs using the MicroFET hand-held dynamometer. Results are for the stronger limb, as identified at baseline.
Time frame: Change from Baseline to Month 12 and Month 20
Health Assessment Questionnaire - Disability Index (HAQ-DI)
The disability index of the HAQ measures self-reported functional status (disability) including the patient's use of aids or devices and/or help from other persons. The scale is composed of 20 items in 8 domains (dressing and grooming, arising, eating, walking, hygiene, reach, grip, and common daily activities). Each domain has at least 2 subcategory items, scored on a scale from 0 to 3, and for each of the 8 domains the domain score was the highest score of the involved subcategory scores. The total score reported is an average over 8 domains and scores from at least 6 domains had to be available for the total score to be calculated. The average total score ranges from 0 to 3, and a higher score corresponds to a worsening in functional status.

2 Minute Walk Test (2MWT)
The distance patients could walk in 2 minutes (during the 6 Minute Walk Test) recorded in meters.
Time frame: Change from Baseline to Month 12 and Month 20
Short Form-36 (SF-36) Mental Component Score
Measured using the Short Form health survey with 36 items (SF-36). The questionnaire measures 8 health concepts which yields 2 summary measures: physical and mental health. The mental component score is composed of energy/fatigue (4 items), social functioning (2 items), role limitations due to emotional problems (3 items), and emotional well-being (5 items). To score the SF-36, scales are standardized with a scoring algorithm to obtain a score ranging from 0 to 100, and the summary measure is calculated as the average score. Higher scores indicate better health status.

Patient Global Impression of Severity (PGIS)
Patient-reported assessment of the impact of IBM on the ability to complete activities of daily living (e.g. dressing, walking, bathing) at the time of the assessment. The response options for the impact of IBM were "none" (i.e. no impact), "very mild", "mild", "moderate", "severe", and "very severe".
Time frame: Change from Baseline to Month 12 and Month 20
Patient Global Impression of Change (PGIC)
Patient-reported assessment of the change from start of study treatment in the impact of IBM on the ability to complete activities of daily living (e.g. dressing, walking, bathing). The response options for change in impact were "very much worse", "much worse", "a little worse", "no change", "a little improved", "much improved", and "very much improved".
Time frame: Change from Baseline to Month 12 and Month 20
Clinician Global Impression of Severity (CGIS)
Clinician-reported assessment of the severity of the patient's IBM symptoms at the time of the assessment. The response options were "none", "very mild", "mild", "moderate", "severe", and "very severe"
Time frame: Change from Baseline to Month 12 and Month 20
Clinician Global Impression of Change (CGIC)
Clinician-reported assessment of the change from start of study treatment in the patient's IBM symptoms. The response options for change in IBM were "very much worse", "much worse", "a little worse", "no change", "a little improved", "much improved", and "very much improved".
