New osteoporosis drug could offer cheaper alternative to prolia

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Postmenopausal women, aged ≥55 and \<80 years at screening. Postmenopausal is defined as 12 months of spontaneous amenorrhea with serum FSH (follicle-stimulating hormone) levels ≥40 mIU/mL at screening or 6 weeks postsurgical bilateral oophorectomy with or without hysterectomy. 2. Evidence of osteoporosis as assessed by lumbar spine (L1-L4) absolute BMD corresponding to a T-score classification ≤-2.5 and ≥-4.0. 3. At least 3 vertebrae in the L1-L4 region and at least one hip joint are evaluable by DXA at screening. 4. Patients with body weight ≥50 to \<90 kg at screening. Exclusion Criteria: 1. Patients with T-score of \<-4.0 at the lumbar spine, total hip, or femoral neck. 2. Known history of previous exposure to denosumab (Prolia®, Xgeva®, or any biosimilar denosumab). 3. For prior or ongoing use of any osteoporosis treatment (other than calcium and vitamin D supplements) following points to be considered for the washout periods prior to the screening visit: a. Oral bisphosphonate i. Ineligible if used for 3 or more years cumulatively ii. If used for \<3 years, a gap of at least 1 year since the last dose is required at the screening visit b. Dose received any time 4. Systemic glucocorticosteroids 5. Patients with ongoing serious infections 6. Evidence of any of the following per the patient's history, DXA, or X-ray review and/or current disease: 1. Patient in bed rest for 2 or more weeks during the last 3 months prior to screening 2. Current hyperthyroidism or hypothyroidism 3. History and/or current hyperparathyroidism or hypoparathyroidism 4. Current hypocalcemia or hypercalcemia based on albumin-adjusted serum calcium 5. Any bone disease including bone metastasis or metabolic disease (except for osteoporosis), eg, osteomalacia or osteogenesis imperfecta, rheumatoid arthritis, Paget's disease, ALP (alkaline phosphatase) elevation (at investigator's discretion), Cushing's disease, clinically significant hyperprolactinemia (at investigator's discretion), fibrous dysplasia, malabsorption syndrome which may interfere with the interpretation of the results 6. History and/or presence of one severe or 3 or more moderate vertebral fractures 7. History and/or presence of hip fracture or bilateral hip replacement 8. Presence of an active healing fracture according to assessment of investigator 9. History of severe skeletal pain with bisphosphonates which, as per the investigator, is a risk to her participation in the trial 10. Oral/dental or periodontal conditions:
