简要总结
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.

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 with primary osteoporosis (diagnosed according to "Diagnostic Criteria for Primary Osteoporosis issued by the Japanese Society for Bone and Mineral Research (1995)."
- •Post-menopausal patients aged 50 years or older.
- •Patients who agree to participate in a 4-year follow-up observation.
- •Patients who provide written informed consent.
- •Exclusion Criteira:
- •Patients on warfarin potassium (Warfarin®) therapy.
- •Patients with hypercalcemia.
- •Patietns with renal calculus.
- •Patients with a known history of hypersensitivity to calcium or menatetrenone preparations.
- •Patients with severe complication in the hepatic, renal, gastrointestinal, cardio- and cerebrovascular system.
- •Patients who underwent bilateral ovariectomy.
- •Patients with radiotherapy in the pelvis or para-aortic area.
- •Patients with the following X-ray findings;
- •Patients showing osteophytes connecting with adjacent vertebral osteophytes
- •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).
