Brief summary
The purpose of this study was to determine the efficacy of repeat dosing with multiple dose levels of bimagrumab on patient physical function, skeletal muscle mass and strength in older adults with sarcopenia. In addition, this study generated data on the safety, tolerability, and pharmacokinetics of bimagrumab in older adults with sarcopenia.
Interventions
Bimagrumab will be administered as an intravenous infusion starting on Day 1 until week 21.
Placebo will be administered as an intravenous infusion starting on Day 1 until week 21.

Participant flow
Recruitment details
A total of 220 patients were randomized to receive six doses of either BYM338 70 mg, BYM338 210 mg, BYM338 700 mg or the placebo. However, only 217 patients were enrolled and dosed with BYM338 or placebo due to the withdrawal of three patients who did not meet the inclusion/exclusion criteria prior to receiving the first dose.

Percentage Change From Baseline to Week 25 on Appendicular Skeletal Muscle Index (ASMI) Measured by Dual Energy X-ray Absorptiometry (DXA)
Change from Baseline to Week 25 on appendicular skeletal muscle index (ASMI) measured by Dual Energy X-ray Absorptiometry (DXA) Appendicular skeletal muscle index (ASMI) is a core requirement for determining the presence of sarcopenia and is calculated as the sum of the appendicular lean mass (kg) of the two upper and two lower limbs quantified by DXA, divided by height (m\^2). Therefore, an increase in ASMI indicates an increase in the quantity of an individual's lean mass.
