A Safety and Pharmacokinetics Study of Ustekinumab Biosimilar GNR-068 and Stelara® in Healthy Volunteers

AO GENERIUM122 enrolled

Overview

This is a randomized open comparative parallel group study of the safety and pharmacokinetics of GNR-068 and Stelara® in healthy volunteers. Participants received a single subcutaneous dose of ustekinumab 45 mg. The follow up period was 84 days.

GNR-068 (ustekinumab) is being developed as a biosimilar to the drug Stelara®, a solution for subcutaneous administration (manufacturer Silag AG, Switzerland, holder of authority Johnson \& Johnson). Ustekinumab is a recombinant human monoclonal antibody against the p40 subunit. The p40 subunit is common to interleukine-23 (IL-23) and IL-12. IL-23 is a dimer consisting of p40 and p19. IL-12 is a dimer consisting of p40 and p35. With its target site p40, ustekinumab blocks two different mechanisms of T cell activation, namely Th1 and Th17 selection. This study is intended for a comparative study of the safety and pharmacokinetics of the drug GNR-068 and the drug Stelara® for the purpose of registration of the drug - GNR-068, 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. 122 patients (60 to the study drug group and 62 to the comparator drug group) were randomized.
