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 administration of low doses of rituximab followed by hydroxychloroquine, prednisone and low doses of mycophenolate mofetil is an effective therapy in Latin American patients with active systemic lupus erythematosus.

Background: In Latin America, the medical attention directed to systemic autoimmune diseases competes with a budget designed to fight poverty, lack of education, etc. In this context, the access to treatments recommended internationally are expensive and limited; therefore, research of methods that make these treatments cheaper is of paramount importance.

Objective: Our objective was to describe the 24-month clinical outcome of patients with active systemic lupus erythematosus (SLE) who received low doses of rituximab (RTX), followed by hydroxychloroquine (HCQ), prednisone and low doses of mycophenolate mofetil (MMF).
