Romosozumab improves microarchitecture as assessed by tissue thickness-adjusted trabecular bone score in postmenopausal women with osteoporosis.

ABSTRACT: Bone mineral density (BMD) is only one of several bone strength determinants affected by osteoporosis therapies. Trabecular Bone Score (TBS), a gray-level texture index determined from lumbar spine (LS) dual-X-ray absorptiometry scans, is an indirect measure of bone microarchitecture independent of and complementary to BMD and clinical risk factors. In the Active-Controlled Fracture Study in Postmenopausal Women with Osteoporosis at High Risk (ARCH), monthly subcutaneous romosozumab 210 mg for 12 mo followed by 24-mo open-label weekly oral alendronate 70 mg (romosozumab-to-alendronate) significantly reduced fracture risk compared to 36-mo alendronate alone in postmenopausal women with osteoporosis and prior fracture. This analysis evaluated tissue thickness-adjusted TBS (TBSTT) in a subgro
