Outcome Measures
Primary Outcome Measures
- To evaluate the efficacy of ENZ215 when compared to Prolia in patients with postmenopausal osteoporosis, in terms of change in bone mineral density (BMD) at lumbar spine [360 days]
Percentage change in BMD at lumbar spine (L1-L4 region) measured by dual-energy X-ray absorptiometry (DXA)
- To compare the area under the effect curve (AUEC) of serum C-telopeptide of Type-1 collagen (sCTX) levels [180 days]
AUEC of sCTX over the initial 6 months (from Day 1 pre-dose to Month 6 pre-dose) will be assessed.
Secondary Outcome Measures
- To compare the immunogenicity potential of ENZ215 and Prolia [540 days]
ADAs incidence at baseline and different timepoints from 1 month to 12 months and during open-label switch over period will be assessed.
- To compare the safety and tolerability of ENZ215 and Prolia [540 days]
Treatment-emergent serious and non-serious adverse events (TEAEs) during main treatment period and open-label switch-over period will be assessed
- To compare the pharmacokinetics of ENZ215 and Prolia [360 days]
Cmax of denosumab measured at predefined timepoints.
- To compare the pharmacokinetics of ENZ215 and Prolia [360 days]
Tmax of denosumab measured at predefined timepoints.
- To compare the pharmacokinetics of ENZ215 and Prolia [360 days]
partial AUC of denosumab measured at predefined timepoints.
- To compare the change in serum procollagen type 1 N-terminal propeptide (sP1NP) levels [180 days]
- To compare the change in BMD at the lumbar spine [180 days]
Percentage change in BMD at lumbar spine measured by DXA from baseline to predefined timepoint
- To compare the change in BMD at total hip and femoral neck [360 days]
Percentage change in BMD at total hip and femoral neck measured by DXA from baseline to Month to predefined timepoint
