Response to netakimab in radiographic axial spondyloarthritis patients with different baseline C-reactive protein, sacroiliitis evaluated by MRI and peripheral joint involvement status: a post-hoc analysis of the ASTERA study.

Objectives: Netakimab is a humanised camelid-derived monoclonal antibody targeting interleukin-17A. Here, we report the results of post-hoc analysis of the ASTERA phase 3 study (NCT03447704, February 27, 2018) in patients with active radiographic axial spondyloarthritis (r-axSpA) grouped by baseline C-reactive protein (CRP), baseline sacroiliac joint (SIJ) inflammation through magnetic resonance imaging (MRI) or presence of peripheral arthritis (PA).

Methods: In this double-blinded, multicentre, randomised, placebo-controlled, phase 3 ASTERA study, 228 adult patients with active r-axSpA received 120 mg of subcutaneous netakimab or placebo at weeks 0, 1, 2, and thereafter every other week.

The efficacy and safety of levilimab in severely ill COVID-19 patients not requiring mechanical ventilation: results of a multicenter randomized double-blind placebo-controlled phase III CORONA clinical study.

Objective And Design: The aim of this double-blind, placebo-controlled, phase III CORONA clinical trial was to evaluate the efficacy and safety of IL-6 receptor inhibitor levilimab (LVL) in subjects with severe COVID-19.

Subjects: The study included 217 patients. The eligible were men and non-pregnant women aged 18 years or older, hospitalized for severe COVID-19 pneumonia.

A phase III study of BCD-055 compared with innovator infliximab in patients with active rheumatoid arthritis: 54-week results from the LIRA study.

BCD-055 is a biosimilar of innovator infliximab (IFX). Here we present the 54-week results from phase 3 clinical study in patients with rheumatoid arthritis (RA). The aim of this study was to demonstrate the equivalent efficacy and safety of BCD-055 and IFX in patients with active rheumatoid arthritis.

Primary efficacy of netakimab, a novel interleukin-17 inhibitor, in the treatment of active ankylosing spondylitis in adults.

Objectives: Netakimab (NTK) is a humanised monoclonal antibody targeting interleukin-17A, previously investigated in a phase 1 trial in healthy volunteers. Here, we report the results of a phase 2 trial, conducted to assess safety and pharmacokinetics (PK), to establish a therapeutic dose of NTK in a target population of patients with active ankylosing spondylitis (AS).

Methods: 89 patients with active AS, despite non-steroidal anti-inflammatory (NSAID) drug treatment, were randomised to receive 40, 80 or 120 mg of subcutaneous NTK or placebo at weeks 0, 1, 2 and q2wk thereafter until week 12.
