A Multicenter, Randomized, Double-blind Comparative Study to Valuating the Efficacy and Safety of QL1206 and Prolia® in Postmenopausal Women With Osteoporosis at High Risk of Fracture
This study is a multicenter, randomized, double-blind comparative study to valuating the efficacy and safety of QL1206 and Prolia® in postmenopausal women with osteoporosis at high risk of fracture.
• Subjects who agree to participate in the study and sign the informed consent form.
• Postmenopausal women who can walk freely, aged 50-85 years (including 50 and 85 years old).
• Subjects whose absolute value of bone mineral density (BMD) in the lumbar or total hip area meets T values ≤ -2.5 and \> -4.0.
• Subjects who must have at least one of the following risk factors: History of previous fragility fractures (occurring after the age of 40); history of hip fractures in fathers or mothers; increased bone turnover rate during screening; low body weight (BMI ≤ 19 kg/m2); advanced age (aged ≥ 65 years); current smoke.
• The duration of spontaneous amenorrhea was \>2 years or \>2 years after bilateral oophorectomy. If the status of bilateral oophorectomy is unknown or if the ovaries are preserved after hysterectomy, follicle stimulating hormone (FSH) levels \>40mIU/mL may be used to confirm the status of postoperative menopause.
