Denosumab (DMAb) significantly improves bone strength at the hip, estimated by FEA from QCT scans, from baseline (B/L) and vs placebo (Pbo) (Keaveny ASBMR 2010). We determined the extent and distribution of mass and thickness changes at the proximal femur, a key skeletal site for fracture risk, using a novel cortical bone mapping technique on the same serial QCT scans. A FREEDOM substudy included 80 women who underwent hip QCT scanning at B/L and months 12, 24 and 36 during DM...

The relationship between BMD T-score and FX risk has not been established in patients receiving osteoporosis therapy. In the FREEDOM Extension study, continuous DMAb therapy for up to 10 years increased BMD levels with no therapeutic plateau at lumbar spine or TH [Bone et al, ASBMR 2015]. Such improvements would only be meaningful if associated with FX reductions. We investigated the relationship between TH BMD T-score and NVFX in women who received DMAb during FREEDOM and tho...

STRUCTURE was a phase 3, open-label study evaluating the effect of romosozumab or TPTD for 12 months in women with postmenopausal osteoporosis transitioning from bisphosphonate therapy (NCT01796301). This study enrolled women with postmenopausal osteoporosis who had taken an oral bisphosphonate for ≥3 years prior to screening and alendronate in the year prior to screening; had a BMD T-score ≤−2.5 at the total hip (TH), lumbar spine (LS), or femoral neck (FN);...
