Korábbi kezelés

• Active or uncontrolled infection requiring systemic therapy within 2 weeks prior to first dose;
• Participating in clinical trials of other medical devices or drugs or reaching less than 30 days or 5 half-lives after the last visit in the clinical trials of other medical devices or drugs (non-bone metabolism related drugs) (whichever is longer, calculated from the date of ICF signing). Bone metabolism related drugs should comply with the corresponding prohibition time limit, and anti-osteoporosis drugs should be excluded. Those who have failed in the screening period of other clinical trials but have not yet been treated with drugs/clinical devices can be included in this study;
• Having received Denosumab and its biosimilars, or Romosozumab and its biosimilars, cathepsin K inhibitor therapy prior to randomization;
• Having received the following osteoporosis treatments, or medications that affect bone metabolism or any herbal medications:
• Use of bisphosphonates(oral or intravenous) ,fluoride and strontium prior to randomization.
• Use of parathyroid hormone (PTH) or PTH analogues, such as teriparatide, within 12 months prior to randomization.
• Use of systemic hormone replacement therapy (HRT), selective estrogen receptor modulators, tibolone, anabolic hormones, testosterone, androgens, gonadotropin releasing hormone agonists, adrenocorticotropic hormone, within 12 months prior to randomization.
• Use of calcitonin, calcitriol, alfacalcidol and vitamin D analogues within 12 months prior to randomization: 5) Use of any of the following within 3 months prior to randomization: heparin, warfarin, anticonvulsants (except benzodiazepines), systemic use of ketoconazole, cinacalcet, aluminum, lithium, protease inhibitors, methotrexate, and oral or parenteral glucocorticoids (≥ 5 mg/day prednisone daily or equivalent for > 10 days).
• Use of any herbal medications within 2 weeks (If the herbal medications contain the above components that affect bone metabolism, should follow the corresponding elution period of bone metabolism components);
• Subjects at very high risk of fracture who must be treated immediately with an active drug in the opinion of the investigator;
• non-smokers (A history of never smoking > 5 cigarettes/day and not smoking at all for at least the last 2 years prior to screening process)
• light smokers (with smoking habit <5 cigarettes/day, smoking period <10 years. Light smokers should have not smoked more than 1 cigarette in the week before starting the medical screening process)
