Analysis of the Immunogenicity from Abatacept-Treated Pediatric Patients With Polyarticular-Course Juvenile Idiopathic Arthritis: Findings From Two Phase III Clinical Trials.

ABSTRACT:

Objective

The goal of this article is to present the analysis of anti-abatacept antibody data from children with polyarticular-course juvenile idiopathic arthritis (pJIA), treated with abatacept. The data are from 395 participants with pJIA from two abatacept registrational trials.

Methods

We analyzed immunogenicity data according to age groups, administration route (intravenous [IV] or subcutaneous [SC]), drug treatment interruption, and co-medications (with or without methotrexate [MTX]) to assess impact on the incidence of anti-abatacept antibodies.

Results

The overall immunogenicity incidences observed in both JIA trials ranged between 4.7% and 23.3%. There was a slightly higher immunogenicity incidence in the 2-5-year-old participants (15.2%) compared with 6-17-y
