Overview
Brief Summary
This is a randomized, double-blind, three-arm, parallel-group, single-dose study to demonstrate bioequivalence of ENZ215 and EU- and US-sourced Prolia after a single 60-mg dose administered subcutaneously in healthy adult male volunteers.
Detailed Description
Approximately 207 subjects will be enrolled into 3 groups (69 in each group) in parallel. The subjects may be enrolled in multiple groups at the site. All eligible subjects will be assigned to one of the three treatment groups in 1:1:1 ratio i.e. ENZ215 or US-sourced Prolia® or EU-sourced Prolia® to enter into the study period of 39 weeks. The study duration will be approximately 16 months (i.e. 6 months of recruitment period, 4 weeks of screening period and approximately 39 weeks (270 days) of study period). Each subject will be required to visit the site for a total of 20 visits: visit 1 - screening visit, visit 2 - day 0 to day 2, visit 3 - day 3, visit 4 - day 4, visit 5 - day 5, visit 6 - day 6, visit 7 - day 8, visit 8 - day 10, visit 9 - day 12, visit 10 - day 16, visit 11 - day 21, visit 12 - day 28 (week 4), visit 13 - day 42 (week 6), visit 14 - day 63 (week 9), visit 15 - day 90 (week 13), visit 16 - day 119 (week 17), visit 17 - day 147 (week 21), visit 18 - day 180 (week 26), visit 19 day - 224 (week 32), and visit 20 - day 270 (week 39). A window period of ±1 day is allowed for visit 12 (day 28), window period of ±3 days are allowed from day 42 (week 6) to day 180 (week 26), A window period of ±5 days are allowed from day 224 (week 32) to day 270 (week 39). End of Study Assessment will be performed on day 270 (week 39) or at the time of early discontinuation of the subject.

Outcomes
Primary Outcomes
Maximum Observed Drug Concentration (Cmax) of ENZ215 and EU- and US-sourced Prolia®
Time Frame: 270 days
A total of twenty four blood PK samples of 2.5 mL each were collected from each subject in the study. Pre-dose sample were collected within 30 minutes prior to IP administration. Post-dose samples up to Day 2 were collected within ± 10 minutes, within ± 2 hours from Day 3 to Day 21, within ± 1 day on Day 28, within ± 3 days from Day 42 to Day 180 and within ±5 days from Day 224 to Day 270. Serum concentrations of denosumab were measured at central laboratory by a validated analytical method.
Area Under the Drug Concentration-time Curve From Day 0 to Day 270 (AUC0-t) of ENZ215, EU- and US-sourced Prolia®. and EU- and US-sourced Prolia®
Time Frame: 270 days
A total of twenty four blood PK samples of 2.5 mL each were collected from each subject in the study. Pre-dose sample were collected within 30 minutes prior to IP administration. Post-dose samples up to Day 2 were collected within ± 10 minutes, within ± 2 hours from Day 3 to Day 21, within ± 1 day on Day 28, within ± 3 days from Day 42 to Day 180 and within ±5 days from Day 224 to Day 270. Serum concentrations of denosumab were measured at central laboratory by a validated analytical method.
Area Under the Drug Concentration-time Curve From Time 0 to Infinity (AUC0-inf) of ENZ215, EU- and US-sourced Prolia®. and EU- and US-sourced Prolia®
