A systematic review and meta-analysis of sequential treatment strategies for osteoporosis.

Abstract

We performed a systematic review and meta-analysis of the efficacy of sequential osteoporosis treatment strategies. Sequential strategies resulting in the greatest BMD gain included romosozumab to denosumab or bisphosphonates; teriparatide to romosozumab or denosumab; and bisphosphonates to romosozumab. These findings can help guide sequential medication choice for patients with osteoporosis. The purpose of this systematic review and meta-analysis was to evaluate the efficacy of sequential osteoporosis medication strategies on bone mineral density (BMD) and fracture outcomes. Pubmed, Embase, and Cochrane Library databases were searched, and pre-specified criteria were applied to select relevant primary studies for inclusion in this systematic review and meta-analysis. Thirty-nine primary studies were included. Meta-analysis summary estimates for BMD change on the second medication in a treatment sequence showed robust BMD gain with bisphosphonates followed by 1 year of romosozumab at the lumbar spine (10.1%, 95% CI 9.9-10.4), femoral neck (3.1%, 95% CI 2.9-3.4), and total hip (3.1%, 95% CI 2.7-3.5). Moderate BMD gains were found with romosozumab followed by 1 year of denosumab, with summary estimates of 4.0% (95% CI 1.2-6.7) at the lumbar spine, 2.2% (95% CI 0.5-3.8) at the femoral neck, and 2.8% (95% CI 0.8-4.9) at the total hip; similar gains were found with teriparatide transitioned to 1 year of denosumab. Bisphosphonates followed by 1 year of denosumab resulted in significant BMD gain at the lumbar spine (3.5%, 95% CI 2.8-4.2), femoral neck (1.5%, 95% CI 1.2-1.9), and total hip (2.1%, 95% CI 1.8-2.3). However, bisphosphonates transitioned to 1 year of teriparatide resulted in significant BMD gain at the lumbar spine (5.1%, 95% CI 4.4-5.9) but not at the hip. These findings provide a rigorous summary of the evidence to guide sequential medication choice for patients with osteoporosis.
