E.2 Objective of the trial
E.2.1Main objective of the trial

Note: This objective will be considered as primary for European Medicines Agency (EMA) submission only; for all other agencies, this objective will be considered as secondary.
E.2.2Secondary objectives of the trial
•To further compare clinical similarity of AVT03 and Prolia
•To assess and compare the safety of AVT03 with Prolia
•To assess and compare immunogenicity of AVT03 with Prolia
•To compare pharmacokinetic (PK) biosimilarity between AVT03 and Prolia
•To compare pharmacodynamic (PD) parameters between AVT03 and Prolia
E.2.3Trial contains a sub-study No
E.3Principal inclusion criteria
1. Postmenopausal women with osteoporosis willing to sign an informed consent form and able to undergo protocol related procedures.

c. Having had bilateral oophorectomy ≥6 weeks prior to Screening
4. Body Mass Index: 18.5-32.0 kg/m2
5. A baseline dual-energy x-ray absorptiometry scan with a T-score ≤ -2.5 and ≥ -4.0 at the lumbar spine (LS) (L1 to L4), and/or total hip and/or femoral neck.
A subject must have a T score within the stated range of ≤ -2.5 and ≥ -4.0 in at least 1 of the 3 areas: - lumbar spine (L1 to L4) - total hip - femoral neck. On the contrary, subjects will be excluded from the trial if the T score is less than -4.0 in at least 1 of the 3 areas (ie, at the LS [L1 to L4], or total hip, or femoral neck).
Note: The left hip should be scanned for the calculation of total hip T score. If the left hip cannot be scanned (eg, due to left hip replacement, etc), the right hip can be scanned instead. The same hip should be used for all dual-energy x ray absorptiometry scans.
6. At least 2 consecutive evaluable lumbar vertebrae and at least 1 evaluable hip.
7. Willing to receive calcium plus vitamin D supplements.
8. No history or evidence of a clinically significant disorder, condition, or disease that, in the opinion of the Investigator, would pose a risk to subject safety.
9. Resting supine systolic blood pressure of ≤150 mmHg and diastolic blood pressure of ≤90 mmHg. Other vital signs showing no clinically relevant deviations according to the Investigator’s judgment.
10. 12-lead electrocardiogram (ECG) recording without signs of clinically relevant pathology or showing no clinically relevant deviations as judged by the Investigator.
11. Subject smokes <10 cigarettes per day within 3 months of Screening. Note: It is strongly recommended that subjects do not smoke during their participation in the study.
12. Recommended to abstain from alcohol from 48 hours prior to study drug administration, and 24 hours prior to study visits.
E.4Principal exclusion criteria

2.History and/or presence of 1severe or more than 1 moderate vertebral fractures confirmed by x-ray (according to Genant semiquantitative method)
3.History of hip fracture
4.Presence of active healing fractures
5.Previous treatment with denosumab and previous use of the following medications:
a.IV bisphosphonates, fluoride, or strontium ranelate at any dose within 5years prior to Screening
b.Oral bisphosphonates used for>3years cumulative use, and any dose within 12months of Screening
c.Parathyroid hormone(PTH) or PTH derivatives, and selective estrogen receptor modulators eg, raloxifene within 1year of Screening
d.Romozosumab within 30days prior to Screening
e.Calcitonin within 6months of Screening

7.Evidence of hypo/hypercalcemia at Screening defined
as<8.6or>10.5mg/dL.
Note: If hypocalcaemia can be excluded based on calcium, corrected calcium, albumin, PTH, vitamin D3 values but ionized calcium is pending,the subject may be randomized, as per Investigator assessment and confirmation that exclusion criterion 7 has not been met. This needs to
be recorded on source documents
8.Known vitamin D deficiency(25-hydroxy vitamin D level <20ng/mL[50nmol/L]) after supplementation at Screening

Note: Any subject with positive anti-HBc at Screening should be reviewed and evaluated by the Investigator to exclude active infection.It is at the Investigator's discretion whether to extend diagnostics to exclude current infection of hepatitis B. A local HBV quantitative DNA by PCR test may be performed within the screening window visit
12.Haematology and chemistry lab. results outside the reference ranges,clinically significant, and, in the opinion of the PI or designee, could cause this study to be detrimental to the subject
