Osteoporosis & bone health

ROMosozumab early experience in female patients with severe osteoporosis in an Italian real-world setting, the ROMEO study

Osteoporos IntPublished Retrospective cohort study

Authors' conclusion

The rapid increase in BMD with romosozumab supports its use for reducing fracture risk in postmenopausal women with severe osteoporosis, regardless of prior bisphosphonate exposure.

Study context

Population
Postmenopausal women with severe osteoporosis newly treated with romosozumab, Italian real-world setting, 29 November 2022 to 01 July 202470 followed to month 6, 41 to month 12
Participants
133 women
Outcome
Achievement of BMD surrogate threshold effect (bone mineral density surrogate threshold effect (BMD-STE)) for minimal fracture risk reduction
Methodological detailsreal-world, single-arm
  • Real-world
  • Single-arm

Main finding

As reported in the abstract

Patients reaching the BMD-STE for minimal fracture risk reduction for all fractures · up to month 6

Reached the STE for minimal fracture risk reduction for all fractures

56.4%

Observational data: associations, not effects.

Further findings

BMD (lumbar spine, femoral neck, total hip)

Significant increases in BMD at all sites (all p < 0.05 vs. baseline)

T-score target (> −2.5) reached among patients with baseline lumbar spine T-score ≤ −2.5 · months 6 and 12

Month 6
18.2%
Month 12
32.0%

Bone turnover markers · months 3 and 6

P1nP increased significantly and CTX decreased significantly (all p < 0.05 vs. baseline)
