Body mass index (BMI) between 18.0 and 30.0 kg/m2, inclusive, at screening. 5. Vital signs showing no clinically relevant deviations according to the Investigator's judgment or their designee's. In the case of subjects \> 45 year-old, if a value of SBP above 145 mmHg is confirmed on rechecking the BP after a period of rest, this subject will not be included in the study. 6. 12-lead ECG recording without signs of clinically relevant pathology or showing no clinically relevant deviations as judged by the Investigator or their designee. Exclusion Criteria: 1. Evidence of clinically relevant pathology: Like have a history of and/or current clinically significant gastrointestinal, renal, hepatic, cardiovascular, haematological, pulmonary, neurologic, metabolic, psychiatric disorder, drug or alcohol abuse, or allergic disease excluding mild asymptomatic seasonal allergies.

Unable to follow protocol instructions or not likely to complete the study in the opinion of the Investigator or their designee. 3. History of relevant drug and/or food allergies (including hypersensitivity to any recombinant protein drug or any of the constituents of denosumab, or latex allergy or hereditary problems of fructose intolerance). 4. Known history of previous exposure to denosumab. 5. Have previously been exposed to a monoclonal antibody or fusion protein (other than denosumab) within 270 days (or 5 half-lives whichever is the longest) prior to randomization and/or there is confirmed evidence or clinical suspicion of immunogenicity from previous exposure to a monoclonal antibody or fusion protein. 6. Prior diagnosis of bone disease, or any condition that will affect bone metabolism such as, but not limited to: osteoporosis, osteogenesis imperfect, hyperparathyroidism, hyperthyroidism, hypothyroidism, osteomalacia, rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, current flare-up of osteoarthritis and/or gout, active malignancy, renal disease (defined as glomerular filtration rate \< 60 mL/min), Paget's disease of the bone, recent bone fracture (within 6 months), malabsorption syndrome. 7. Any use of the following bone modifying medications, with no limitation on time since administration: e.g.intravenous bisphosphonates, strontium, fluoride (if administered in treatment of osteoporosis),romosozumab, teriparatide or any parathyroid hormone analogs, calcitonin, and cinacalcet.
