Description
Bimagrumab is a fully human monoclonal antibody that acts as an activin type II receptor (ActRII) antagonist. It is designed to block ligands such as myostatin and activins that inhibit muscle growth, thereby promoting muscle mass and strength. Bimagrumab has been investigated for the treatment of conditions associated with muscle wasting and metabolic dysfunction, including sporadic inclusion body myositis (sIBM), sarcopenia, and obesity-related metabolic disorders. Although not yet FDA-approved for any indication, clinical studies have shown promise in improving body composition and glycemic control, particularly in patients with type 2 diabetes and obesity.

Directions
Bimagrumab is administered via intravenous (IV) infusion, typically once every four weeks. The exact dosing and treatment schedule may vary based on the indication under investigation. Clinical administration should occur under medical supervision, with pre-infusion assessment and post-infusion monitoring for adverse effects.
Ingredients
Active Ingredient: Bimagrumab (recombinant human monoclonal antibody targeting ActRIIA/B)
Formulation details (as per investigational drug): Sterile solution for IV infusion, composition includes buffer agents and stabilizers appropriate for monoclonal antibody preservation. Full excipient list is proprietary pending regulatory approval.
Contraindications
As Bimagrumab remains an investigational product, no formal contraindications are established; however, it should not be administered to individuals with known hypersensitivity to monoclonal antibodies or any components of the investigational formulation. Use in pregnant or breastfeeding women is not recommended due to lack of safety data.
Cautions
Patients should be monitored for infusion-related reactions, including hypersensitivity, hypotension, and fever. The long-term safety profile remains under investigation, and caution is advised in populations with cardiovascular or renal comorbidities. As a growth-promoting agent, off-target effects on non-skeletal muscle tissues and tumorigenesis are theoretical risks and are being evaluated in ongoing studies.
Side Effects
In clinical trials, the following side effects have been reported:
Infusion-related reactions
Muscle cramps
Headache
Upper respiratory tract infections
Gastrointestinal discomfort
Transient elevations in liver enzymes
No long-term adverse effects have been confirmed, but surveillance continues in ongoing Phase II and III trials.
