Kumar S, Beck BR, Nery L, Byth K, Elhindi J, Wood C, Fuller OK, Clifton-Bligh RJ, Girgis CM. Study protocol for the ROLEX-DUO randomised placebo-controlled trial: ROmosozumab Loaded with EXercise - DUal effects on bone and muscle in postmenopausal Osteoporosis and Osteopenia. BMJ Open. 2024 Aug 24;14(8):e086708. doi: 10.1136/bmjopen-2024-086708. PMID: 39181562; PMCID: PMC11344515.

Study has 3 arms

  1. romosozumab with supervised High Intensity Resistance and Impact Training (HiRIT)
  2. romosozumab with unsupervised low-intensity exercise
  3. placebo with unsupervised low-intensity exercise

Co-primary outcomes

  • mean percentage change in lumbar spine bone mineral density (BMD), and
  • mean change in five times sit-to-stand test performance (seconds) at 8 months.

Secondary/exploratory outcomes

  • BMD changes at the femoral neck, total hip and distal radius
  • three-dimensional dual-energy X-ray absorptiometry (DXA) hip outcomes
  • DXA-derived lean and fat mass
  • serum markers of bone turnover (procollagen type 1 peptide, C-telopeptide of type 1 collagen)
  • bone biomarkers (dickkopf-1)
  • serum extracellular vesicle analyses
  • 36-Item Short Form Survey (SF-36) quality-of-life scores
  • Menopause-Specific Quality Of Life (MENQOL) Questionnaire
  • menopause symptom burden scores,
  • number of falls and fractures.

Mixed-effects models will be performed to compare longitudinal outcome results between groups using intention-to-treat analysis.

Status

  • Enrollment: began April 2024
  • Enrollment completed: Dec 2025
  • Study completion: expected Sept 2026
