About this trial

The objective of this study was to conduct a randomized, double-blind, double-dummy active controlled trial to determine the efficacy of denosumab in treating sarcopenia with underlying osteoporosis.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Elderly males or females aged 65 years or older

diagnosed with osteosarcopenia (sarcopenia diagnosis based on AWGS 2019 guidelines - low appendicular skeletal muscle mass (ASM) by Dual-energy X-ray absorptiometry (DXA) (M:<7.0kg/m2, F:<5.4kg/m2) AND low handgrip strength (M:<28kg, F:<18kg) OR low physical performance (6-metre walk: <1.0m/s or 5-time chair stand test ≥ 12 s); osteoporosis diagnosed based on World Health Organization (WHO) criteria with DXA scan T-score ≤ -2.5)

Willing and able to comply with study protocol including follow-up evaluations.

Disqualifiers

history of recent fracture i.e., within 3 months

history of prior anti-osteoporotic drug

disease or medication affecting bone or muscle metabolism

Chairbound or bedbound

  • Zolendronic Acid

    Drug

    5mg intravenous Zoledronic Acid (100mL solution) once yearly and subcutaneous placebo (1mL normal saline) every 6 months

Trial outcomes

Primary outcomes

1

6-metre walk

The time taken to walk 6 metres without deceleration. Average result of 2 trials is recorded. Slow speed is defined as \<1.0m/s.

Time frame
From enrollment to the end of treatment at 52 weeks
2

5-time chair stand test

The time to rise from a chair 5 times is recorded. The cut-off for is taken at \>=12 seconds.

Time frame
From enrollment to the end of treatment at 8 weeks
3

Appendicular skeletal muscle mass (ASM)

Determined with Dual-energy X-ray absorptiometry (Horizon®, DXA system, Hologic, USA). Total ASM by DXA is evaluated by segmented measurement of muscle mass at four limbs by operator-defined cutlines at specific anatomical landmarks. ASM is adjusted to square of height to calculate ASMI (kg/m2). Low ASMI by DXA is \< 7 kg/m2 for men and 5.4 kg/m2 for women.

Time frame
From enrollment to the end of treatment at 52 weeks
4

Handgrip strength

Assessed by spring-type hand dynamometer (JAMAR Hand Dynamometer 5030JO). Cut-off for men is \< 28kg, and female is \<18kg. Maximum reading of 3 trials using dominant hand in a maximum-effort isometric contraction

Time frame
From enrollment to the end of treatment at 52 weeks

Secondary outcomes

1

Falls

To assess the occurrence of falls, patients are required to self-report via a fall calendar, which will be returned at 1-year

Time frame
From enrollment to the end of treatment at 52 weeks
2

Fracture

Assess occurrence of a fracture within a year of study period.

Time frame
From enrollment to the end of treatment at 52 weeks
3

Quality of life Short Form-36 (SF-36)

The highest score is 900, and the lowest score is 0. Highest score indicates a better quality of life.

Time frame
From enrollment to the end of treatment at 52 weeks
4

Physical activity scale for elderly (PASE)

It assesses the types of activities typically chosen by older adults, ranging from 0 to 793, with higher scores indicating greater physical activity

Time frame
From enrollment to the end of treatment at 52 weeks
