Arms and Interventions

Arm Intervention/Treatment
Experimental: ENZ215

ENZ215 Injection:- 60 mg Denosumab (ENZ215) will be administered subcutaneously on day 1.

Biological: ENZ215
Enrolled women with postmenopausal osteoporosis will receive ENZ215 (60mg)

Active Comparator: Prolia

Prolia Injection:- 60 mg Denosumab (Prolia) will be administered subcutaneously on day 1.

Biological: Prolia
Enrolled women with postmenopausal osteoporosis will receive Prolia

Outcome Measures

Primary Outcome Measures

  1. 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)

  2. 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

  1. 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.

  2. 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

  3. To compare the pharmacokinetics of ENZ215 and Prolia [360 days]

    Cmax of denosumab measured at predefined timepoints.

  4. To compare the pharmacokinetics of ENZ215 and Prolia [360 days]

    Tmax of denosumab measured at predefined timepoints.

  5. To compare the pharmacokinetics of ENZ215 and Prolia [360 days]

    partial AUC of denosumab measured at predefined timepoints.

  6. To compare the change in serum procollagen type 1 N-terminal propeptide (sP1NP) levels [180 days]

  7. 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

  8. 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
