Sponsor's own description

This two-year open-label pilot clinical trial will evaluate the efficacy and safety of romosozumab to treat bone loss in females with chronic spinal cord injury (SCI) and osteoporosis (OP). Participants will receive monthly injections of romosozumab during the first 12 months of the study. During the second year, participants will take oral alendronate tablets on a weekly basis.
