Bimagrumab

What it is & what research shows

Study example available

Bimagrumab is listed as a biologic in the muscle & performance section of this catalog. A source-verified explanation of its mechanism and uses has not yet been completed here; the catalog category is not evidence of benefit.

One selected study: A double-blind trial examined cardiac effects of blocking the myostatin-activin receptor pathway. 68 healthy older adults aged 60 to 86; not all completed treatment. Intravenous bimagrumab 10 mg/kg or placebo every 4 weeks over 24 weeks. No significant between-group differences in left-ventricular mass index or ejection fraction emerged. Lean mass increased and fat mass decreased. Muscle spasms occurred in 57.1% versus 6.1%. Small, single-site study with substantial attrition. The findings do not establish long-term cardiovascular safety or safety in people with heart disease. [2.1]

Selected study reading notes

Source-linked summaries with studied methods. These are separate from the automated summary counts above and are not formal quality appraisals.

Human

Can fat mass fall while lean mass increases?

48 weeks; IV bimagrumab every 4 weeks, with diet and exercise counseling in both groups.

Demonstrated findings

At 48 weeks, fat mass changed by −20.5% with bimagrumab versus −0.5% with placebo; lean mass changed by +3.6% versus −0.8%.

Limitations & adverse findings

The report analyzed treatment completers, which can affect interpretation. The abstract provides limited adverse-event detail.

What might this mean? · interpretation

The result supports studying activin-receptor blockade for body composition.

What might this mean, and what would change the interpretation?

75 adults with type 2 diabetes and overweight or obesity were randomized; 58 completed. This was not a GLP combination trial and does not establish preserved strength.

What would clarify this: Controlled combination trials measuring both muscle composition and function.

Uses & research

Uses have not been independently checked for this profile. Browse the original studies to see the conditions and populations investigated.

Known half-life

No source-verified value in this profile yet. A treatment schedule or duration of an effect is not a drug half-life.

Half-life describes how quickly the measured drug concentration falls by half. It does not set a dosing interval.
Evidence & important limits

A catalog entry does not establish effectiveness, safety or approval. Study findings and quality appraisal remain separate.

Safety & evidence boundaries

Source-specific information, not a personal safety clearance or monitoring plan.

A compound-specific safety synthesis is not available here yet. Lack of listed adverse effects does not establish safety.

Human study: The report analyzed treatment completers, which can affect interpretation. The abstract provides limited adverse-event detail. Source

Explore safety questions by system

These are literature filters, not claims that this compound causes each effect. A keyword match is not a confirmed adverse reaction.

Interactions, rare harms, long-term effects and reversibility require separate evidence. Do not infer they are absent when the sources here do not address them.

Identity, names & formulations

Canonical compound: Bimagrumab · bimagrumab

No additional aliases recorded.

Names share a parent research page. Different esters, salts, routes and brands are not assumed to have the same half-life, indication or exposure.

Combination evidence stays attached to the studied combination. It is not automatically assigned to each ingredient.

Understand the evidence types

Read the model and design first, then the population, outcome and limitations. These categories describe evidence, not a best-compound ranking.

Randomized human trials
Compare assigned interventions. Randomization does not by itself establish low bias or relevance to every population.
Controlled human studies
Use a comparison group; allocation and confounding still matter.
Prospective human research
Follows participants forward. It may be observational or interventional, so this is not a separate quality grade.
Observational human research
Describes associations. Confounding can explain differences.
Case reports and series
Useful for unusual events and safety signals, not reliable rates or effect sizes.
Animal research
Can test biology and function in a living model. Human exposure, benefit and safety remain separate questions.
Cell and tissue research
Tests responses in a preparation, including human-derived cells. It is not a human participant trial.
Mechanistic and computational evidence
Helps explain or predict a pathway; predictions need experimental and clinical testing.
Anecdotal reports
Self-reported experiences can generate questions. Product identity, selection bias and other interventions may be uncontrolled.

Systematic reviews synthesize studies and depend on their quality. Preprint status and abstract versus full-paper reading are separate labels. Citation popularity measures attention, not reliability. A study summary is not a formal quality appraisal.
