Can a bone drug rebuild muscle? trial tests denosumab for sarcopenia
NCT ID NCT07056478
First seen Sep 16, 2026 · Last updated Sep 17, 2026 · Updated 1 time
Summary
Researchers are testing whether denosumab, a drug usually used for bone loss, can improve muscle strength and quality of life in older adults with sarcopenia after a hip fracture. The trial enrolls 130 people aged 65 and older who have low muscle mass and weakness. Participants receive either denosumab injections every six months or zoledronic acid infusions once a year, and researchers measure changes in muscle strength, physical performance, and balance over time.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- denosumab, a drug that blocks a protein involved in bone breakdown, given as a shot every six months
- What this could lead to
- If denosumab helps, it could become a new way to treat muscle loss and weakness in older adults recovering from a hip fracture, improving their strength and daily function.
- What could go wrong
- The trial is relatively small and focuses on a specific group of patients after hip fracture, so results may not apply to other people with sarcopenia. Denosumab can lower calcium levels and increase infection risk, and it is not yet proven to build muscle.

Inclusion Criteria: * Elderly aged 65 years or older * Diagnosed with sarcopenia following AWGS guidelines - low appendicular skeletal muscle mass measured by dual-energy x-ray absorptiometry (Cutoff: Male \<7.0kg/m2, and female \<5.4kg/m2) AND low handgrip strength (Cutoff: Male \< 28kg, Female \<18 kg) OR low physical performance (6-metre walk, cutoff: \<1.0m/s or 5-time chair stand test \>=12s) * Diagnosed with a hip fracture from low-energy mechanism (e.g., falling from standing height) requiring an operation * Willing and able to comply with study protocol including follow-up evaluations. Exclusion Criteria: * open fracture * multiple fractures * pathological fractures e.g., tumour, infection, etc. * history of medication or disease affecting bone metabolism e.g., hypo/hyperthyroidism * malignancy * chairbound or bedbound (unable to perform assessments) * serious cognitive problems e.g., severe dementia (unable to agree for consent) - renal impairment with glomerular filtration rate \<30 mL/min * prior anti-osteoporotic medication e.g. bisphosphonates, denosumab, etc. * active infection, * severe malnutrition i.e. Mini Nutritional Assessment \< 17 points * serious neurological or neuromuscular conditions e.g. Parkinson's disease * uncontrolled chronic conditions e.g. poorly controlled diabetes mellitis * not anaesthetically fit for operation or conservative management
