Detailed Description
this is a randomized, double-blinded, parallel, active-controlled clinical phase III study. the primary objective is to evaluate the efficacy and safety of CMAB807 treatment compared with Prolia in Chinese postmenopausal women with osteoporosis at high risk of fracture.
Subjects should sequentially enrolled according to the protocol in one of two arms. Subjects who entered in test arm would receive 60mg of CMAB807 subcutaneously every 6 months for one year, while those who entered in control arm should receive 60mg of Prolia subcutaneously every 6 months for one year. Meanwhile, every subject should taking 600mg calcium and 400IU vitamin D daily from successfully screening to the end of study.

- Based on the results of dual energy X-ray absorptiometry, BMD of lumbar spine(L1~L4), femoral neck or total hip: -4.0<T-Score≤-2.5;
There must be at least one of the following risk factors:
- History of osteoporotic fracture;
- Father's and mother's hip fracture history, or both parents';

Suffering from the following oral diseases:
- Osteomyelitis or osteonecrosis of the jaw, previously or currently;
- Actue dental or mandibular disease requiring stomatological surgery;
- Planned invasive dental surgery during the trial period;
- Dental or stomatological surgery have not healed;
Conditions which can influence bone mineral density determination by dual energy X-ray absorptiometry:
- Less than two lumbar vertebrae can be measured;
- Height, weight or waistline may hinder accurate measurement;
- Other conditions that may affect bone density testing
Received anti-osteoporosis drugs or those drugs may affect bone metabolism:
- Use of injectable bisphosphonates, fluoride or strontium within 2 years before screening;
- Use of oral bisphosphonates: more than 2 years, or more than 3 months but less than 2 years and discontinued from last dosage less than 1 year, simultaneously;
- Usage of any drugs which may affect bone metabolism within 6 weeks before screening: parathyroid hormone or parathyroid hormone analogue(such as teriparatide); assimilative hormone or testosterone; glucocorticoid(equivalent to prednisone>5mg/day for more than 10 days); systemic hormone replacement therapy; selective estrogen receptor regulator(such as reloxifene); tibolone; calcitonin; active vitamin D and ite analogues, other bone active drugs include anticonvulsant drugs(except benzodiazepines) and he[arin; long-term systemic use of ketoconazole, androgen, adrenocorticotropic hormone, cinacalcet, aluminum, lithium, protease inhibitors, methotrexate, gonadotropin releasing hormone agonist;
- Patients who have received RANKL inhibitors previously;
- Positive HIV antibody;
- Known alcoholism or drug abuse(during 12 months before screening), because alcohol or drug abuse may interfere with subject's understanding or finish of trial;
- Known allergy to test drug, reference drug or basic drug and its excipients;
- Participate in interventionary clinical study(drug or device) within one month before screening;
- Other serious, acute or chronic diseases, mental disorders or laboratory abnormalities, which are judged by investigator to be unsuitable to participate this study.
