Clinical Trial Summary

This study will evaluate whether the once weekly administration of the combination tablet alendronate/vitamin D3 (FOSAMAX PLUS) will increase lumbar spine bone mineral density (BMD) more than the daily use of calcitriol.

Description:

This was a 6-month, randomized, open-label, active-comparator controlled, parallel-group study with a 6-month extension to evaluate the safety and efficacy of alendronate sodium 70 mg plus vitamin D3 5600 IU combination tablets versus calcitriol in the treatment of osteoporosis in postmenopausal women in China. Participants were randomly assigned to receive alendronate 70 mg plus vitamin D3 5600 IU combination tablet once weekly orally or calcitriol 0.25 μg daily orally.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Extension Study: Percentage of Participants With Serum 25-Hydroxyvitamin (OH) D <20 ng/mL at Month 12	The term "vitamin D insufficiency" is used to describe vitamin D levels that are low enough to cause secondary hyperparathyroidism, bone loss, and increased risk of skeletal fracture. In this study, a threshold for vitamin D insufficiency was a level of serum 25(OH) D <20 ng/mL.	Baseline and Month 12
Primary	Base Study: Percentage Change From Baseline in Lumbar Spine Bone Mineral Density (BMD) at Month 6	BMD at the lumbar spine was assessed by dual energy X-ray absorptiometry (DXA) at baseline and Month 6.	Baseline and Month 6
Primary	Extension Study: Percentage Change From Baseline in Lumbar Spine BMD at Month 12	BMD at the lumbar spine was assessed by DXA at baseline and Month 12.	Baseline and Month 12
Secondary	Base Study: Percentage Change From Baseline in Serum Procollagen Type 1 N-Terminal Propeptide (s-P1NP) at Month 6	s-P1NP is a biochemical marker of bone turnover that is particularly useful in monitoring bone resorption, a process by which bone is broken down within the body. s-P1NP was measured at baseline and Month 6.	Baseline and Month 6
Secondary	Base Study: Percentage Change From Baseline in Serum C-Telopeptides of Type 1 Collagen (s-CTx) at Month 6	s-CTx is a biochemical marker for bone turnover that has been shown to detect increased bone resorption, a process by which bone is broken down within the body. s-CTx was measured at baseline and Month 6.	Baseline and Month 6
Secondary	Extension Study: Percentage Change From Baseline in s-P1NP at Month 12	s-P1NP is a biochemical marker of bone turnover that is particularly useful in monitoring bone resorption, a process by which bone is broken down within the body. s-P1NP was measured at baseline and Month 12.	Baseline and Month 12
Secondary	Extension Study: Percentage Change From Baseline in s-CTx at Month 12	s-CTx is a biochemical marker for bone turnover that has been shown to detect increased bone resorption, a process by which bone is broken down within the body. s-CTx was measured at baseline and Month 12.
