Effect of anti-glucarpidase antibodies on serum methotrexate (MTX concentrations after glucarpidase. (A) MTX concentrations pre- and post-glucarpidase in patients with and without anti-glucarpidase antibody formation. Blue line reflects MTX concentrations in patient with anti-glucarpidase antibodies and red, without. (B) Heat map of MTX rebound data as % of pre-glucarpidase MTX concentration. Cell label represents dose of glucarpidase, either 2000 or 1000 units. Thickened border indicates presence of neutralizing anti-glucarpidase antibody.
