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

Phase 1

Completed

Conditions: Healthy

Interventions: Biological: BCD-089

Registration Number: NCT03103438

Lead Sponsor: Biocad

Brief Summary: 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.

Detailed Description: 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.

Arm && Interventions

Group	Intervention	Description
Cohort 4	BCD-089	This cohort includes 3 subjects who will receive the single subcutaneous injection of BCD-089 at a dose of 1.0 mg/kg. If at least 2 subjects are observed to have DLT, this dose level is defined as the MTD (unless only 3 patients have been treated at that level, in which case it is the tentative MTD). If 0 of the 3 subjects are observed to have DLT, the dose level is escalated one step for the next cohort no. 5 of 3 subjects, and the process continues as above. If exactly 1 of the 3 subjects treated show DLT, 3 additional subjects are treated at the current dose level. If none of these additional 3 patients show DLT, the dose level is escalated for the next Cohort no. 5.
Cohort 5	BCD-089	This cohort includes 3 subjects who will receive the single subcutaneous injection of BCD-089 at a dose of 1.6 mg/kg. If at least 2 subjects are observed to have DLT, this dose level is defined as the MTD (unless only 3 patients have been treated at that level, in which case it is the tentative MTD). If 0 of the 3 subjects are observed to have DLT, the dose level is escalated one step for the next cohort no. 6 of 3 subjects, and the process continues as above. If exactly 1 of the 3 subjects treated show DLT, 3 additional subjects are treated at the current dose level. If none of these additional 3 patients show DLT, the dose level is escalated for the next Cohort no. 6.
Cohort 1	BCD-089	his cohort includes one subject who will receive the maximum safe starting dose of BCD-089 (0.06 mg/kg) subcutaneously. If the dose limitating toxicity occurs within the first seven days after injection the study will be stopped. If there is no DLT within mentioned above period then Cohort no.2 is included.
Cohort 3	BCD-089	This cohort includes 3 subjects who will receive the single subcutaneous injection of BCD-089 at a dose of 0.625 mg/kg.If at least 2 subjects are observed to have DLT, this dose level is defined as the MTD (unless only 3 patients have been treated at that level, in which case it is the tentative MTD). If 0 of the 3 subjects are observed to have DLT, the dose level is escalated one step for the next cohort no. 4 of 3 subjects, and the process continues as above. If exactly 1 of the 3 subjects treated show DLT, 3 additional subjects are treated at the current dose level. If none of these additional 3 patients show DLT, the dose level is escalated for the next Cohort no. 4.
Cohort 2	BCD-089	This cohort includes 3 subjects who will receive the single subcutaneous injection of BCD-089 at a dose of 0.3 mg/kg.If at least 2 subjects are observed to have DLT, this dose level is defined as the MTD (unless only 3 patients have been treated at that level, in which case it is the tentative MTD). If 0 of the 3 subjects are observed to have DLT, the dose level is escalated one step for the next cohort no.3 of 3 subjects, and the process continues as above. If exactly 1 of the 3 subjects treated show DLT, 3 additional subjects are treated at the current dose level. If none of these additional 3 patients show DLT, the dose level is escalated for the next Cohort no. 3.
Cohort 6	BCD-089	This cohort includes 3 subjects who will receive the single subcutaneous injection of BCD-089 at a dose of 2.2 mg/kg. If at least 2 subjects are observed to have DLT, this dose level is defined as the MTD (unless only 3 patients have been treated at that level, in which case it is the tentative MTD). If 0 of the 3 subjects are observed to have DLT, the dose level is escalated one step for the next cohort no. 7 of 3 subjects, and the process continues as above. If exactly 1 of the 3 subjects treated show DLT, 3 additional subjects are treated at the current dose level. If none of these additional 3 patients show DLT, the dose level is escalated for the next Cohort no. 7.
Cohort 7	BCD-089	This cohort includes 3 subjects who will receive the single subcutaneous injection of BCD-089 at a dose of 2.9 mg/kg. If at least 2 subjects are observed to have DLT, this dose level is defined as the MTD (unless only 3 patients have been treated at that level, in which case it is the tentative MTD). If exactly 1 of the 3 subjects treated show DLT, 3 additional subjects are treated at the current dose level.
