871The present phase II/III, multicenter, randomized, double-blind, parallel group comparative study is designed to evaluate the efficacy and safety of once-monthly oral administration of NE-58095 delayed release (DR) tablets for 12 months in participants with involutional osteoporosis. For this study, participants receiving oral NE-58095 immediate release (IR) 2.5 mg tablets once daily for 12 months are set as the control group.
The primary objective of the present study is to verify the non-inferiority of once-monthly oral administration of NE-58095 DR tablets for 12 months to once-daily oral administration of NE-58095 IR 2.5 mg tablets for 12 months, in terms of efficacy in participants with involutional osteoporosis.
Secondary objectives of the present study are as follows: to compare the safety of once-monthly oral administration of NE-58095 DR tablets for 12 months with the safety of once-daily oral administration of NE-58095 IR tablets (at 2.5 mg) for 12 months in participants with involutional osteoporosis at time of wakening.

New non-traumatic vertebral fractures were identified by interpretable X-ray images of 13 vertebrae from the fourth thoracic to the fourth lumbar vertebra. A Central Review Committee member for X-ray determined the presence or absence of new vertebral fractures, the number of new fractures, the presence or absence of worsening pre-existing vertebral fractures, and the number of worsened fractures. The assessment of new vertebral fractures and the worsening of pre-existing vertebral fractures was semiquantitative. The X-ray images were visually inspected and classified into normal (Grade 0), mild deformation (Grade 1), moderate deformation (Grade 2), or severe deformation (Grade 3). If the assessment of any vertebra became worse by at least 1 grade after starting the treatment, its height was measured. A new vertebral fracture or a worsening pre-existing vertebral fracture was concluded if the vertebra's height was reduced from the baseline by at least 20% and by at least 4 mm.
