MILAN, Italy-Giving interleukin-2 (IL-2, aldesleukin, Proleukin) in combination with the anti-CD20 monoclonal antibody rituximab (Rituxan) may increase the antibody’s efficacy in lymphoma patients, apparently because it increases the number of natural killer (NK) cells. Researchers at a Clinical Development Conference sponsored by Chiron Corporation suggested that IL-2 be studied as a regular addition to rituximab therapy and also as an addition to rituxi-mab/chemotherapy regimens.
