A Randomized, Double-blind, Single-dose, Two-arm Parallel Study to Compare the Pharmacokinetics and Safety of BAT1806 Prefilled Subcutaneous Injection With RoActemra® in Healthy Chinese Male Subjects

Phase 1

Active, not recruiting

• Conditions: Healthy Men
• Interventions: Drug: BAT1806 prefilled subcutaneous injection/RoActemra® (from EU)

• Registration Number: NCT05968508
• Lead Sponsor: Bio-Thera Solutions

Brief Summary

This is a randomized, double-blind, single-dose, two-arm parallel study to compare the pharmacokinetics, safety and immunogenicity of BAT1806 prefilled subcutaneous injection with RoActemra® (from EU) in healthy male subjects.

Detailed Description

A total of 150 subjects are planned to be enrolled and 1:1randomized to receive single dose of 162 mg/0.9 mL BAT1806 injection, or RoActemra® (from EU) subcutaneously.

A 14-day screening period is set in this study. Subjects will be admitted one day prior to administration (Day -1) and can be discharged only upon completion of relevant observations and evaluations after administration on Day 5. After discharge, subjects need to return to the hospital for 10 follow-ups as required in the study.
