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/Vitamin D3 5600 I.U. Combination Tablets Versus Calcitriol in the Treatment of Osteoporosis in Postmenopausal Women in China
Abstract
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.
Conditions: Osteoporosis, Postmenopausal.
Primary outcome: Base Study: Percentage Change From Baseline in Lumbar Spine Bone Mineral Density (BMD) at Month 6; Extension Study: Percentage Change From Baseline in Lumbar Spine BMD at Month 12.
Enrollment: 219 participants.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 219 participants or records.
