Figure 1. Evolution of Antirituximab Antibody (ARA) Serum Levels From Months 12 to 36 in the 13 Patients With ARAs.
The ARA serum levels were measured by enzyme-linked immunoassay at month 12 following the initial rituximab (RTX) infusion performed at baseline, and at month 36 after the 2 maintenance infusions of RTX at months 12 and 18 (arrows). Relapsing patients are identified in orange. The medians are represented by the horizontal lines.
