Anti-CD20 C2B8/SAAnti-CD20 antibody (C2B8) conjugated to SA followed by 30 mCi/m2 or 50 mCi/m2 of 90Y-DOTA-biotin was administered to patients with relapsed NHL in a phase I/II study. Six of seven patients exhibited objective responses (3 CR and 1 PR). Five of the seven patients showed transient grade III hematological toxicity. The estimate of tumor to whole body dose ratio was 38:1.[67]
