MITO: Muscle Impact of Treating Osteoporosis
Study Details
Study Description
Brief Summary
Osteosarcopenia is a geriatric musculoskeletal syndrome characterized by co-existence of osteoporosis and sarcopenia (low skeletal muscle mass, strength, and/or functional capacity). There is strong evidence of overlap between the pathophysiology of osteoporosis and sarcopenia (muscle-bone crosstalk). This research plan will further explore the relationship between bone and muscle, and provide new information about effect of osteoporosis medications on muscle health in older adults who are under treatment for osteoporosis.

|---|---|
| Active Comparator: Zoledronic Acid
|
Drug: Zoledronic Acid
Twenty participants will randomly receive zoledronic acid 5 mg intravenous infusion at month 0 with denosumab placebo at month 0 and 6. All forty participants will receive zoledronic acid 5 mg intravenous infusion at month 12.
Other: Denosumab Placebo
Twenty participants who will randomly receive zoledronic acid 5 mg intravenous infusion at month 0 will also receive denosumab placebo at month 0 and 6.

| Active Comparator: Denosumab
|
Drug: Denosumab
Twenty participants will randomly receive denosumab 60 mg subcutaneous injection at month 0 and 6 with zoledronic acid placebo at month 0.
Other: Zoledronic Acid Placebo
Twenty participants who will randomly receive denosumab 60 mg subcutaneous injection at month 0 and 6 will also receive zoledronic acid placebo.

Outcome Measures
Primary Outcome Measures
- Percentage change from baseline in muscle mass (kg) measured by D3-Creatine [Baseline vs Month 12]
D3-Creatine dilution method is a novel method to measure muscle mass
- Percentage change from baseline in appendicular lean mass (ALM/body mass index) [Baseline vs Month 12]
Appendicular lean mass is measured by whole body DXA scan and is an index of skeletal muscle mass
- Percentage change from baseline in trabecular bone score (TBS) [Baseline vs Month 12]
TBS is measure of bone microarchitecture and is measured by a DXA system. A value of ≥ 1.35 indicates a normal architecture while TBS ≤ 1.20 indicates degraded microarchitecture
- Percentage change from baseline in bone mineral density (BMD) (g/cm²) [Baseline vs Month 12]
BMD is measured by a DXA scan system and a higher BMD is correlated with lower fracture risk
- Percentage change from baseline in grip strength (kgf) [Baseline vs Month 12]
Grip strength is measure of muscle strength and will be measured by a standard hand dynamometer
- Percentage change from baseline in gait speed (m/s) [Baseline vs Month 12]
Gait speed is a measure of muscle function and will be measured by standard 4 meter gait speed test
- Percentage change from baseline in rectus femoris muscle thickness (cm) [Baseline vs Month 12]
This variable will be measured by ultrasound
- Percentage change from baseline in rectus femoris muscle cross-sectional surface area (cm²) [Baseline vs Month 12]
This variable will be measured by ultrasound

-
Subjects with severe liver disease or
-
Those who have been on oral bisphosphonates for the past 1 year and intravenous bisphosphonates for the past 2 years prior to the study or
