Study Endpoints

Primary Endpoints

Number of Participants With Adverse Events (AEs), Serious Adverse Events (SAEs) and Deaths.
to end of study (up to 14 months, including the 6-month treatment-free follow-up period)

Safety monitoring was conducted throughout the study. AEs starting on or after the day of first administration of extension study drug until last administration of study drug + 56 days are considered. SAEs starting on or after the day of first administration of extension study drug are considered. Deaths which occurred on or after the day of first administration of extension study drug are considered.

Change From Core Study Baseline in 6 Minute Walking Distance Test (6MWD)
Core study baseline, weeks 52, 78, 104, and >=117

The 6MWD test measures the distance (in meters) that a participant can walk in a 6 minute time frame. A positive change from baseline indicates improvement. The efficacy analysis and time points were based on windowed visits relative to the first dose of the double-blind treatment in the core study.

Number of Participants With Adverse Events as a Measure of Safety and Tolerability
Up to 29 month

Any Adverse Event was defined as occurrence of any symptom regardless of intensity grade, Serious Adverse Event (SAEs) assessed as medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization or result in persistent or significant disability/incapacity

Change From Baseline in 6 Minute Walking Distance (6MWD) Test at Week 52
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.

Percentage Change From Baseline of Thigh Muscle Volume (TMV) by MRI Scan at Week 4, 8, 16, and 24
Baseline, Weeks 4, 8, 16, 24

Thigh Muscle Volume (TMV) change was evaluated by a responder analysis. Patients whose loss of muscle TMV by MRI was no more than or equal to 2% at Week 4,8,16 and 24 was considered responders.

Frequently asked questions about BYM338

What is BYM338 used for?

BYM338 is an investigational drug being studied for conditions involving skeletal muscle, including sporadic inclusion body myositis, sarcopenia, and chronic obstructive pulmonary disease (COPD) with cachexia. It has also been investigated in type 2 diabetes mellitus. BYM338 is in Phase 2 clinical development and is not approved by the FDA.

Who makes BYM338?

BYM338 is being developed by Novartis AG, which trades under the ticker NVS. The drug is currently in Phase 2 clinical trials for multiple muscle-related conditions, including sarcopenia and COPD with cachexia.

What phase is BYM338 in?

BYM338 is in Phase 2 clinical development. It has completed three Phase 2 trials, with no active trials currently ongoing. The drug remains investigational and has not received FDA approval.

What clinical trials is BYM338 in?

BYM338 has completed several Phase 2 trials, including NCT01601600 in sarcopenic adults, NCT01669174 in COPD patients with cachexia, NCT02333331 in sarcopenia, and NCT02468674, a 24-week off-drug extension study in sarcopenic elderly. All trials are completed.

Is BYM338 the same as bimagrumab?

BYM338 is also known as bimagrumab. The drug is being studied under the name bimagrumab in clinical trials for sarcopenia and other muscle-wasting conditions. Both names refer to the same investigational compound developed by Novartis.
