Brief Summary:
A 24-week off drug extension parallel group study assessing the durability of effect on skeletal muscle strength and function following a 6-month double-blind placebo-controlled study evaluating bimagrumab in older adults with sarcopenia

Condition or disease Intervention/treatment Phase
Sarcopenia Drug: bimagrumab Drug: Placebo Phase 2

Detailed Description:
The primary objective is to assess the durability of effect of bimagrumab (BYM338) as measured by the short physical performance battery (SPPB) total score at week 49.

Official Title: A 24-week Off Drug Extension Parallel Group Study Assessing the Durability of Effect on Skeletal Muscle Strength and Function Following a 6-month Double-blind Placebo-controlled Study Evaluating Bimagrumab in Older Adults With Sarcopenia
Actual Study Start Date : July 22, 2015
Actual Primary Completion Date : December 3, 2018
Actual Study Completion Date : December 3, 2018

Arm Intervention/treatment
Follow-up (arm 1)
All subjects enter an off-drug follow-up until Week 49.
Drug: bimagrumab

bimagrumab low dose bimagrumab moderate dose bimagrumab high dose

Bimagrumab was administered as an intravenous infusion starting on Day 1 until week 25 in the core study. No intervention in the extension study.

Follow-up (arm 2)
All subjects enter an off-drug follow-up until Week 49.
Drug: Placebo


Placebo was administered as intravenous infusion from Day 1 to Week 25 in the core study. No intervention in the extension study.

Primary Outcome Measures :
  1. Short Physical Performance Battery score [ Time Frame: Week 49 ]
    Balance test, gait speed test and chair rise test each yielding a score on a scale from 0 to 4 (total score 0-12, with the higher score reflecting a higher level of function).

Secondary Outcome Measures :
  1. 6-minute walking distance [ Time Frame: Weeks 25, 37, 49 ]
    Total distance walked during a 6 minute time period expressed in meters

  2. Gait speed [ Time Frame: Weeks 25, 37, 49 ]
    Speed of habitual walking over a 4 meter distance in m/sec

  3. Total lean body mass measured by dual energy X-ray absorptiometry (DXA) [ Time Frame: Weeks 25, 37, 49 ]
    Weight of lean mass of the total body

  4. Appendicular skeletal muscle index measured by DXA [ Time Frame: Weeks 25, 37, 49 ]
    The sum of legs and arms expressed in kilograms (kg)
