AVT03 With Prolia in Healthy Male Subjects
Study Details
Study Description
Brief Summary
This study has been designed as a randomized, double-blind, parallel-group study and in healthy adult male subjects of age 28 years to 55 years old. The study will assess the PK, PD, safety and tolerability of AVT03 compared to Prolia when administered as a single 60 mg SC dose

Detailed Description
The study will consist of a 4 week screening period, a 252 day (36 weeks) treatment and assessment period, and an End of Study (EOS) visit on week 36 on Day 252. Subjects will undertake a screening visit between Day -28 and Day -1 to determine their eligibility for the study. Subjects who meet the eligibility criteria will be admitted to the study site on the day prior to dosing (Day -1), during which their continued eligibility will be assessed up to Day 1 prior to dosing. On Day 1, eligible subjects will be randomized and will receive a single dose of 60mg AVT03 or 60mg Prolia as subcutaneous injection.

Outcome Measures
Primary Outcome Measures
- Area under the serum concentration-(AUC0-t) from day 0 to day 252 [Day 1(week 1) to Day 252 (week 36)]
Venous blood samples will be collected for measurement of Area under serum concentration-time curve (AUC 0-t) AVT03 and Prolia
- Maximum serum concentration Cmax [Day 1(week 1) to Day 252 (week 36)]
Venous blood samples will be collected for measurement of maximum serum concentration of AVT03 and Prolia
Secondary Outcome Measures
- PD_AUC0-last for CTX-1 (% inhibition)C terminal telopeptide of type 1 collagen) [Day 1(week 1) to Day 252 (week 36)]
Venous blood samples will be collected for measurement of serum concentration of AVT03 and Prolia
- Area under the concentration-time curve AUC0-24 [Day 1(week 1) to Day 162 (week 24)]]
Venous blood samples will be collected for measurement of serum concentration of AVT03 and Prolia
- Adverse Events [Screening to Day 252 (week 36)]
Adverse events will be coded using MedDRA and grouped by system organ class and preferred term and summarised, by treatment group at the time of onset of the AE. The summary tables will present the number and percentage of total subjects and number of events, by system organ class and by preferred term. Injection related reactions will be listed and summarized by reaction using frequency counts and percentage, by treatment group.

Exclusion Criteria:
-

Any current active infections, including localized infections, or any recent history (within 1 week prior to IP administration) of active infections, cough or fever, or a history of recurrent or chronic infections
-
Known or suspected clinically relevant drug hypersensitivity to denosumab or any of its constituents, which in the opinion of the Investigator, contraindicates the subject's participation
-
