Bone drugs may double as liver fat fighters — a trial puts them to the test
NCT ID NCT05493761
First seen Jul 23, 2026 · Last updated Jul 24, 2026 · Updated 1 time
Summary
This trial investigates whether two common osteoporosis medications, denosumab and alendronate, can reduce liver fat and scarring in postmenopausal women who also have nonalcoholic fatty liver disease (NAFLD). The study will compare changes in liver fat and stiffness over 12 months in women receiving either drug. If denosumab proves effective, it could offer a new treatment avenue for NAFLD, a condition with no approved medications.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- denosumab or alendronate (anti-osteoporosis medications)
- What this could lead to
- If denosumab reduces liver fat and fibrosis, it could point toward a new use for an existing osteoporosis drug in treating NAFLD.
- What could go wrong
- This is a small, non-randomized study, so results may not be conclusive. Denosumab can cause side effects like bone or joint pain, and its effect on the liver is still uncertain.

Inclusion Criteria: * postmenopausal women aged \> 40 years * diagnosis of osteoporosis, or osteopenia and Fracture Assessment Risk (FRAX) score indicative for initiation of anti-osteoporotic treatment, or osteopenia and history of low-energy fracture. Evaluation of osteopenia and osteoporosis will be based on bone mineral density (BMD) of the lumbar spine and/or the femoral neck of the non-dominant hip measured with dual energy X-ray absorptiometry (DXA) * diagnosis of NAFLD based on non-invasive indices of hepatic steatosis * written informed consent Exclusion Criteria: * mean ethanol consumption \>10 g/day * a history of other chronic liver disease (e.g., viral hepatitis, autoimmune hepatitis, primary sclerosing cholangitis, primary biliary cholangitis and overlap syndromes, drug-induced liver injury, hemochromatosis, Wilson's disease, α1-antitrypsin deficiency) * liver cirrhosis * any malignancy * chronic kidney disease * uncontrolled hypothyroidism or hyperthyroidism * use of the following medications within a 12-month period before baseline associated with drug-induced fatty liver: interferon, tamoxifen, amiodarone, aloperidin, glucocorticosteroids, anabolic steroids, any medication against tuberculosis, epilepsy or viruses, methotrexate, parenteral nutrition * use of the following medications within a 12-month period before baseline associated probably with improvement in fatty liver: vitamin E, pioglitazone, insulin, glucagon-like peptide-1 receptor agonists (GLP-1RAs), sodium-glucose co-transporter-2 inhibitors (SGLT-2), orlistat, ursodeoxycholic acid * use of any anti-osteoporotic medication within a 12-month period before baseline, except for calcium and vitamin D
