First-in-human Study of Safety, Pharmacokinetics and Pharmacodynamics of Various Doses of BCD-089 in Healthy Subjects

This is an open label, phase 1, "3+3" dose escalating study of tolerability, safety, pharmacokinetics, pharmacodynamics and immunogenicity of a single subcutaneous injection of the novel monoclonal antibody against the interleukin-6 receptor - BCD-089. The study will enroll 19 healthy male volunteers.

IL-6 is a new potential therapeutic target which plays important role in pathogenesis of several autoimmune disorders including rheumatoid arthritis. BCD-089 is a novel fully human monoclonal antibody against the interleukin-6 receptor developed by JCS BIOCAD (Russia) which is now on the first step of clinical evaluation. BCD-089-1 study is the first-in-human clinical trial which is intended to evaluate tolerability, safety, pharmacokinetics, pharmacodynamics and immunogenicity of BCD-089 when used as a single step-by-step escalating subcutaneous dose in healthy male volunteers. During this study it is expected to determine diapason of safety doses of BCD-089 (incl. MTD) which thereafter can be evaluated in phase 2 studies.
