Experimental: BYM338/bimagrumab 10 mg/kg
Participants received study medication with BYM338 at 10 mg/kg from Day 1 to Week 52 and up to Week 104, administered by intravenous (i.v.) infusion every 4 weeks.
|
Drug: BYM338/bimagrumab
BYM338, a 150 mg/mL concentrate for solution for i.v. infusion, was provided in colorless glass vials with a rubber stopper and aluminum flip-off caps. |
Experimental: BYM338/bimagrumab 3 mg/kg
Participants received study medication with BYM338 at 3 mg/kg from Day 1 to Week 52 and up to Week 104, administered by i.v. infusion every 4 weeks.

- Change From Baseline in 6 Minute Walking Distance (6MWD) Test at Week 52 [ Time Frame: Baseline, Week 52 ]The 6MWD test measured the distance (in meters) that a participant walked in a 6 minute timeframe. A positive change from baseline indicates improvement.
- Estimated Within Treatment Group Lean Body Mass (LBM) Ratio at Week 52 [ Time Frame: Baseline, Week 52 ]LBM was measured via dual energy x-ray absorptiometry (DXA) and calculated as (LBM at Week 52/LBM at baseline)*100 . A positive change from baseline indicates improvement.
- Change From Baseline in Quadriceps Quantitative Muscle Testing (QMT) on the Right Side at Week 52 [ Time Frame: Baseline, Week 52 ]Quadriceps muscle strength was measured by portable fixed dynamometry (PFD) on the right side. A negative change from baseline indicates deterioration.
- Change From Baseline in Sporadic Inclusion Body Myositis (sIBM) Functional Assessment (sIFA) Score at Week 52 [ Time Frame: Baseline, Week 52 ]Self-reported physical function was assessed by a newly developed patient reported outcome named sporadic inclusion body myositis (sIBM) functional assessment (sIFA). The sIFA consists of 11 items scored on an 11 point numerical rating scale from 0 (no difficulty) to 10 (unable to do) across 3 domains: upper body functioning, lower body functioning and general functioning. Participants completed the assessment where the recall period was the past week prior to completing the patient reported outcome (PRO). The total score on the sIFA scale ranges from 0 (minimum) to 110 (maximum). Higher values represent a worse outcome. A positive change from baseline indicates deterioration.
- Estimated Annual Number of Falls Per Patient Within Treatment Group [ Time Frame: Week 52 ]Participants documented any fall occurrences in a paper diary during the study.
- Change From Baseline in Short Physical Performance Battery (SPPB) Score at Week 52 [ Time Frame: Baseline, Week 52 ]The SPPB evaluated lower extremities function by testing gait speed, ability to keep standing balance and time to rise from a chair five times. The sub-score for each test ranged from 0 to 4. The summary score, which was a summation of scores from the 3 tests, ranged from 0 to 12. An increase in score indicates improvement in physical performance. A negative change from baseline indicates deterioration.
