Denosumab vs Alendronate After Vertebroplasty
Study Details
Study Description
Brief Summary
Osteoporotic vertebral compression fracture (OVCF) patients had a proportion of secondary fractures after percutaneous vertebroplasty (PVP). Denosumab and alendronate is both effective to prevent bone loss for OVCF postmenopausal women. However, trial evidence comparing effect of denosumab vs zoledronate after PVP was unknown. The study aims to assess the efficiency of denosumab vs alendronate for OVCF patients bone mineral density (BMD), bone turnover markers (BTMs), secondary fracture and adverse events after PVP

Detailed Description
Whether denosumab was non-inferior than alendronate in improving bone mineral density (BMD), bone turnover markers (BTMs), functional status questionnaires, and secondary fracture in elderly patients with OVCF after PVP remains unknown. A prospective, randomized, placebo-controlled clinical trial in OVCF patients with PVP was performed. This study aimed to investigate the efficiency of denosumab vs alendronate on BMD, BTMs, functional status, secondary fracture rate, and adverse events in OVCF patients after PVP during a 12-month follow-up period.

Outcome Measures
Primary Outcome Measures
- Lumbar bone mineral density(BMD) [up to 12 months]
Lumbar vertebral (L1 to L4, except the surgery segment) BMD were determined at baseline, 6 and 12 months via dual energy X-ray
- Total hip BMD [up to 12 months]
Total hip BMD were determined at baseline, 6 and 12 months via dual-energy X-ray.
- Femoral neck BMD [up to 12 months]
Femoral neck BMD were determined at baseline, 6 and 12 month via dual-energy X-ray
- Procollagen type 1 n-terminal propeptide (P1NP) [up to 12 months]
Bone formation marker, P1NP were determined at baseline, 6 and 12 months after surgery.
- C-terminal cross-linked type 1 collagen terminal peptide (CTX) [up to 12 months]
Bone resorption marker, CTX were determined at baseline, 6 and 12 months after surgery
- Visual analog scale (VAS) back [up to 12 months]
The VAS score for back pain were determined at baseline, 6 and 12 month. Use a ruler about 10cm long, one side is marked with "0" and the other "10" respectively. A score of 0 indicates no pain, 10 indicates the most unbearable pain
Secondary Outcome Measures
- The Roland-Morris Disability Questionnaire [up to 12 month]
The Roland-Morris Disability Questionnaire is scored by 24 adding up the number of items checked "yes" on different low back pain-related daily activity disabilities. Total scores range from 0 to 24, with higher scores 24 indicating a higher level of disability related to low back pain and lowest 0 represents no back pain
- The QUALEFFO-31 Questionnaire [up to 12 month]
The Quality of Life Questionnaire of the European Foundation for Osteoporosis-31 (QUALEFFO-31), which contains three domains including pain, physical function, and mental function. This scale is assessed on a scale of 0 to 100, with 0 indicating the highest QoL and 100 the lowest
- The EQ-5D Questionnaire [up to 12 month]
The EuroQol five-dimension (EQ-5D) questionnaire evaluates health status consisting five dimensions: mobility, selfcare, performance of usual activities, pain or discomfort, and anxiety or depression. After conversion, the index was between 0 and 1.0 (minimum score: 0, indicating worst health state; full score:1.0, indicating full health).
- Secondary fracture rate [up to 12 month]
Secondary fracture rate containing vertebral fracture and non-vertebral fracture was assessed at 12 month after surgery. The lowest score was 0, the highest score was 100%. The lower score 0 represents no secondary fracture.
- Adverse events [up to 12 month]
The main adverse events including deep venous thrombosis, pneumonia, acute renal failure, pulmonary embolism, myocardial infarction, influenza, transfer to intensive care unit, joint pain, headache, nausea, osteonecrosis of the jaw, atypical femoral fracture and rash.
