IV administration of unlabeled tositumomab (TST) (450 mg) was infused over 1 hour (hr) prior to a 30 minute infusion of 35 mg TST trace labeled with 5 millicurie (mCi) iodine I 131. Participants received at least 3 doses (4 drops by mouth, 3 times a day [TID]) of a saturated solution of potassium iodide (KI), 3 doses (20 drops by mouth, TID) of Lugol's solution, or KI tablets (130 mg by mouth, once a day) 24 hrs or more prior to administration of the DD and continued daily for 14 days following the therapeutic dose (TD). The TD was administered 7 to 14 days after the dosimetric dose. The TD was an IV infusion of 450 mg TST over 1 hour, followed by infusion of 35 mg of TST radiolabeled with iodine I 131 to deliver the appropriate total body dose of 75, 65, or 45 centigray (cGy) over 20 minutes. |
