This is a randomized single-blind comparative parallel group study of the safety, pharmacokinetics and pharmacodynamics of GNR-086 and Ilaris® in healthy volunteers. Participants received a single subcutaneous dose of canakinumab 150 mg. The follow up period was 120 days.

GNR-086 (canakinumab) is being developed as a biosimilar to the drug Ilaris®, a lyophilisate for the preparation of solution for subcutaneous administration.

Canakinumab is a recombinant human monoclonal antibody against human interleukine-1β that belongs to the immunoglobulin G1/k (IgG1/k) isotype subclass.

This study is intended for a comparative study of the safety, pharmacokinetics and pharmacodynamics of the drug GNR-086 and the reference drug Ilaris® for the purpose of registration of the drug - GNR-086 (JSC GENERIUM, Russia), 150 mg, lyophilisate for the preparation of solution for subcutaneous administration in the Russian Federation. The study included healthy volunteers aged 18-45 years at the time of signing the informed consent form. The study included a screening period, single administration of study/comparator drug and a follow up period. Allocation of patients to treatment groups was carried out by randomization in a ratio of 1:1 to the study drug and comparator drug. 105 patients (53 to the study drug group and 52 to the comparator drug group) were randomized.
