研究组 & 干预措施
Arm 1
Participants underwent two phases of treatment: an initial DD, followed by a therapeutic dose. The one-day DD comprised a 1 hr IV infusion of 450 mg unlabeled TST, followed by a 20 min IV infusion of 35 mg TST labeled with 185 MBq (5.0 mCi) of I 131. After 7 to 14 days, the one-day therapeutic dose comprised a second 1 hr IV infusion of 450 mg unlabeled TST, followed by a 20 min IV infusion of 35 mg TST labeled with I 131 with an administered activity (MBq or mCi) determined from the dosimetry calculation.
干预措施: Tositumomab 450 mg (Drug)

结局指标
主要结局
Response Rate
时间窗: Week 26
Responders are defined as participants with Complete Response (CR: disappearance of all clinical and radiological evidence of lymphoma), Clinical Complete Response (CCR: all criteria met for CR, except there is a residual nodal mass \>15 millimeters), or Partial Response (PR: 50% reduction in the sum of the products of the longest perpendicular diameters of all measurable lesions with no new lesions). Response is based on objective evaluation, using the guidelines developed by The International Workshop to Standardize Response Criteria, independent of the investigator's evaluation.
次要结局
- Complete response rate (CR)(From the start of treatment (Study Day 0, Baseline) until long-term follow-up (every 6 months until 5 years from the time of study entry))
- Duration of response(5 years)
- Progression-free survival (PFS)(5 years or until death)
- Adverse events(5 years or until death)
- Quality of Life(5 Years)
- Resource Utilization Assessment(Week 26)
- Duration of Overall Survival(5 years or until death)
