| OG000 | TST and Iodine I 131 TST | Participants received a dosimetric dose (DD) consisting of 450 milligrams (mg) of tositumomab (TST) intravenously (IV) followed by 5.0 millicurie (mCi) of Iodine I 131 and 35 mg of TST IV. The therapeutic dose (TD) consisting of 450 mg of TST IV, followed by a participant-specific dose of I 131 (75 centigray [cGy] or 65 cGy) and 35 mg of TST IV, was administered 7-14 days after the DD. Participants who had disease progression or had completed at least 2 years of follow-up after administration of TST/I 131 TST during the TD phase and had signed the informed consent to participate in the Long-Term Follow-Up (LTFU) study (BEX104528) were followed for up to 10 years. Participants did not receive any study medication during the LTFU study. |

| Secondary | Number of Participants Who Became Positive or Negative for Human Anti-murine Antibody (HAMA) After Study Treatment | Tositumomab is a murine (mouse) antibody. Participants in this study were evaluated to determine if they developed a human anti-murine antibody (HAMA) immune response after administration of tositumomab and iodine I 131 tositumomab. | | Posted | | Number | | participants | | Par. were evaluated until death/disease progression or 2 years in Study BEX104505. Par. who completed 2 years in BEX104505 were followed in study BEX104528 for up to 125 months. Data are included from both Study BEX104505 and Study BEX104528. | | | | ID | Title | Description |

Participants did not receive any study medication during the LTFU study. |

| Secondary | Time to HAMA Positivity From First Dosimetric Dose | Time to HAMA positivity is defined as the time from the first dosimetric dose to the first reported HAMA-positive result for the participant. | ITT Exposed Population. Participants who converted to HAMA positivity were analyzed. | Posted | | Median | Full Range | days | | Par. were evaluated until death/disease progression or 2 years in Study BEX104505. Par. who completed 2 years in BEX104505 were followed in study BEX104528 for up to 125 months. Data are included from both Study BEX104505 and Study BEX104528. | | | | ID | Title | Description |

Participants did not receive any study medication during the LTFU study. |

| Secondary | Number of Participants in the Indicated Categories of Thyroid Function Assessment | Hypothyroidism, a condition in which the thyroid gland does not produce enough thyroid hormone (resulting in the elevation of thyroid stimulating hormone [TSH] in the blood), may result from treatment with radioactive iodine I 131. A thyroid blockade medication was given prior to administration of the study drug and up to 2 weeks after the therapeutic dose to prevent the uptake of I 131 in the thyroid gland. Thyroid function was determined periodically, including during follow-up, in order to assess if there was any effect of the I 131 on thyroid function, such as hypothyroidism. | ITT Exposed Population. Participants who were evaluable for thyroid function assessment and who had no elevated TSH level or hypothyroidism at baseline were analyzed. | Posted | | Number | | participants | | Par. were evaluated until death/disease progression or 2 years in Study BEX104505. Par. who completed 2 years in BEX104505 were followed in study BEX104528 for up to 125 months. Data are included from both Study BEX104505 and Study BEX104528. | | | | ID | Title | Description |

| Secondary | Number of Days Each Participant Took to Reach Hypothyroidism After the First Dosimetric Dose | Hypothyroidism is a condition in which the thyroid gland does not produce enough thyroid hormone (resulting in the elevation of thyroid stimulating hormone [TSH] in the blood). | ITT Exposed Population. Participants experiencing hypothyroidism were analyzed. | Posted | | Number | | days | | Par. were evaluated until death/disease progression or 2 years in Study BEX104505.
