Abstract

Introduction: Evidence on second-line agents for osteoporosis and osteopenia associated with glucocorticoid use after first-line bisphosphonate therapy is limited. We, therefore, examine the efficacy of denosumab on bisphosphonate-treated osteoporosis and osteopenia in Japanese systemic rheumatic disease (SRD) patients receiving glucocorticoids.

Materials And Methods: Glucocorticoid-treated SRD patients with a pre-existing fragility fracture, either lumbar spine (LS) or femoral neck (FN) bone mineral density (BMD) T-score of ≤ -2.5 or of ≤ -1.5 without a significant increase in BMD in the past year despite oral bisphosphonate therapy were enrolled in this study. They were randomized to switch to 60 mg subcutaneous denosumab every six months (switching group) or to continue the bisphosphonate (continuing group). The primary endpoint was the percent change from baseline in BMD at the LS and FN at week 52.

Results: Of the 39 subjects, 19 were assigned to the switching group and 20 to the continuing group. The switching group showed significant increases in LS BMD (5.7% vs. 1.1%, p = 0.002) and FN BMD (4.2% vs. -0.3%, p = 0.008) at week 52 than the continuing group, with a significant decrease in serum tartrate-resistant acid phosphatase 5b (-28.1% vs. 7.0%, p < 0.001) and improved patient satisfaction.

Conclusion: Switching to denosumab demonstrated greater efficacy than continuing bisphosphonates in increasing BMD, inhibiting osteoclast activation, and enhancing patient satisfaction in Japanese bisphosphonate-treated osteoporosis and osteopenia patients with concomitant SRD receiving glucocorticoids.
