Furthermore, subjects with spine/bone-related medical history (prior to SCI) that in the opinion of the investigator are not yet resolved or previous lesions that are located in the same area of the study SCI should also be excluded., Subjects with dysphagia or inability to swallow tablets., Women who are breastfeeding or who are pregnant.
