Sequential Treatment With Romosozumab Followed by Denosumab vs. Zoledronic Acid for Gains in HIP BMD (STRONG-HIP)

2026년 8월 18일 업데이트: Mattias Lorentzon, Sahlgrenska University Hospital

Short-course Romosozumab Followed by Denosumab Versus Zoledronic Acid: A Multicentre Randomized Active-controlled Trial in Postmenopausal Women at High Fracture Risk

Osteoporosis is associated with a high risk of fractures, disability, loss of independence, and excess mortality. Zoledronic acid is an established first-line treatment in Sweden, but many patients at high fracture risk remain at substantial residual fracture risk. Short-course treatment with romosozumab followed by denosumab produces large increases in bone mineral density, but has not been directly compared with zoledronic acid.

STRONG-HIP is a multicentre, randomized, active-controlled phase 4 trial in 216 postmenopausal women aged 60 years or older with osteoporosis and high fracture risk. Participants are randomized 1:1 to receive romosozumab 210 mg monthly for 3 months followed by denosumab 60 mg every 6 months, or zoledronic acid 5 mg intravenously at baseline and Month 12.

The primary objective is to determine whether the romosozumab-denosumab sequence produces a greater percentage increase in total hip bone mineral density from baseline to Month 24 than zoledronic acid. Secondary outcomes include total hip and lumbar spine BMD at earlier time points, vertebral and clinical fractures, bone turnover markers, safety, health-related quality of life, and health-economic outcomes. A mechanistic substudy will assess bone microarchitecture and estimated strength using HR-pQCT.

Participants are followed for 24 months in the main study and may enter an optional extension with follow-up to Month 48 to assess the durability of treatment effects.

The subject is at high fracture risk, defined by at least one of the following: a previous low-trauma fracture after age 50 years (excluding skull, face, fingers and toes); FRAX probability at or above the age-specific Swedish intervention threshold (using Nordic and Nordic borne calculations, as appropriate) in use at screening.
  5. Corrected plasma calcium or ionized calcium is within the local reference range before randomization.
  6. Serum 25-hydroxyvitamin D concentration ≥50 nmol/L before randomization.
  7. Adequate renal function for zoledronic acid treatment, defined as creatinine clearance ≥35 mL/min calculated using the clinical trial center specified calculation procedure (e.g. the Cockcroft-Gault equation) before randomization.

  17. Current participation, or recent participation within 30 days or five half-lives (whichever is longer), in another interventional clinical trial that could affect safety or data interpretation.
  18. Any other medical, psychiatric, social or logistical condition that, in the investigators opinion, makes participation unsafe or would compromise protocol adherence or data reliability.

기간
Model-Predicted Fracture Risk Reduction Based on Total Hip BMD
기간: Month 24
Fracture-specific relative and absolute risk reductions will be estimated from the adjusted randomized between-group difference in percent change from baseline in total hip BMD at Month 24. The treatment difference will be translated into expected fracture-risk reductions using prespecified validated meta-regression models underpinning the FDA-qualified total hip BMD surrogate endpoint. Estimates may include hip, vertebral, nonvertebral, and all clinical fractures, according to the available validated models.
