Randomized, Open, Parallel, Active Controlled Study on Fracture Prevention in Antiosteoporosis Treatment (OF Study)
Study Details
Study Description
Brief Summary
To investigate a new incidence and preventive effect of menatetrenone on vertebral fracture in patients with osteoporosis who were randomly assigned to either treatment arm receiving daily dose of calcium supplement as a monotherapy (calcium monotherapy group) or menatetrenone plus calcium supplement as a combination therapy (menatetrenone combo therapy group) for 36 months, followed by a 12-month follow-up observation to examine the preventive effect on the fracture risk.

Outcome Measures
Primary Outcome Measures
- New incidence of vertebral fracture at 36 months. vertebral fracture is morphological transformation. []
Secondary Outcome Measures
- New incidence of clinical fracture (upper forelimb, femur, radius, and vertebral fracture associated with severe trauma that can cause fracture in normal bones of young adults) at 48 months []
Eligibility Criteria
Criteria
Inclusion Criteria:
Inpatient or outpatient is not asked. If using any anti-osteoporotic agent other than calcium preparations (i.e., contraindicated for concomitant use stipulated in the protocol of this post-marketing study), such agent must be discontinued. Even after the discontinuation, calcium dosing is permitted with a condition that the subsequent use is started after a 8-week elapse from the discontinuation.

-
Patients showing hyperostosis of ligament around the vertebral body

Patients showing inter-body fusion
-
Patients who experienced surgical intervention(s) in the spine
-
Patients with scoliosis which disturbs a diagnosing of vertebral fracture
-
Patients who have been treated with anti-osteoporotic agents, other than calcium preparation, within 8 months prior to the study treatment (but not applied to the following; if discontinued, non-treated, or shifted to calcium monotherapy for 8 weeks or longer before starting the study treatment).
