Signals for mineralization and inflammation are observed following treatment with fasinumab, a specific nerve growth factor inhibitor
Authors' conclusion
In this post hoc analysis, signals for bone turnover/mineralization, and inflammation increased following treatment with fasinumab. Increases were generally dose-dependent, reversible, and more pronounced in patients with arthropathy than those without.
Study context
- Population
- Patients with OA of the knee or hip in phase 2 and 3 clinical studies of fasinumab
- Participants
- 5,772 patients
- Comparison
- Fasinumab-treated OA patients with arthropathies vs without arthropathies
