Brief summary
This is an open label, phase 1, 3+3, placebo-controlled dose escalating study of tolerability, safety, pharmacokinetics, pharmacodynamics and immunogenicity of a single subcutaneous injection of the novel monoclonal bispecific antibody against human IL-17/TNFa. The study will enroll 28 healthy male volunteers.
Detailed description
Simultaneous blockade of IL-17 and TNFa is a potential therapeutic way of treatment of several autoimmune disorders. BCD-121 is a novel humanized monoclonal bispecific antibody against human IL17 and TNFa developed by JCS BIOCAD (Russia) which is now on the first step of clinical evaluation. BCD-121-1 study is the first-in-human clinical trial which is intended to evaluate tolerability, safety, pharmacokinetics, pharmacodynamics and immunogenicity of BCD-121 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-121 (incl. MTD) which thereafter can be evaluated in phase 2 studies.
