Recruiting now · Phase 1

Conditions studied: Healthy

In brief

The goal of this clinical trial is to investigate the safety, tolerability, pharmacodynamics, pharmacokinetics, and immunogenicity of BCD-261 after single subcutaneous injection at ascending doses and proposed therapeutic doses to healthy male subjects aged from 18 to 45 years old. The study consists of the first stage (dose escalation) and the second stage (dose expansion).
