Clinical Trial of Consolidation Treatment With Iodine I 131 Tositumomab for Multiple Myeloma

"The Bexxar therapeutic regimen is delivered in two sets of intravenous infusions given 7-14 days apart. Nonradioactive Tositumomab is given before both the dosimetric infusion and the therapeutic infusion to improve distribution of these doses throughout the body. A trace amount of radioactive Iodine 131 attached to Tositumomab is initially given to enable physicians to evaluate the clearance of radiation from your body with gamma camera scans. Calculations made on the basis of these individualized radiation clearance rates allow the therapeutic dose (given 7-14 days after the dosimetric infusion) to be tailored for each patient. The therapeutic dose contains Tositumomab labeled with the amount of Iodine 131 tositumomab specifically calculated for you based on the scans performed following the dosimetric dose."
