Summary

The results from Phase 1/2 (RIT-I-000) and Phase 2 (RIT-II-001) studies of Tositumomab and Iodine I 131 Tositumomab (TST/I-131 TST) demonstrated that TST/ I-131 TST produced a high response rate in patients with chemotherapy-relapsed/refractory, low-grade or transformed low-grade Non-Hodgkin's Lymphoma (NHL). On the basis of these results this study was designed to compare the efficacy of TST/ I-131 TST to the last qualifying chemotherapy regimen in patients with chemotherapy-refractory, low-grade or transformed low-grade NHL.

Interventions

BIOLOGICAL

Tositumomab and Iodine I 131 Tositumomab

Dosimetric Dose: 450 mg of TST infused over 70 minutes (inclusive of a 10-minute flush) immediately followed by I-131 TST (35 mg of TST, of which 1-2 mg had been labeled with 5 mCi of Iodine-131) infused over 30 minutes (inclusive of a 10-minute flush). Therapeutic Dose: 7 to 14 days after the dosimetric dose, 450 mg of TST infused over 70 minutes (inclusive of a 10-minute flush) immediately followed by I-131 TST (35 mg of TST labeled with enough Iodine-131 to administer the specified whole body radiation dose determined for the subject) infused over 30 minutes (inclusive of a 10-minute flush). The desired total body dose was 65 cGy for subjects with a baseline platelet count of 100,001-149,999/mm3 and 75 cGy for patients with a baseline platelet count ≥150,000/mm3. Obese patients received an attenuated dose by not including subject mass over 137% of their calculated lean body mass in their calculated lean body mass in the dose calculation.
