Number of Participants Who Were Negative for Human Anti-murine Antibodies (HAMA) at Baseline (Study Entry) But Positive or Negative at Weeks 12 and 25 and at Months 12, 18, and 24

The administration of murine antibodies may form HAMA. A HAMA assay was performed using the ImmunoSTRIP HAMA IgG enzyme-linked immune absorbent assay by a central laboratory (Covance Classic Laboratory Services, Indianapolis, IN). Fludarabine, a known immunosuppressant, might decrease HAMA production in addition to reducing bone marrow involvement. To be positive, a participant had to have a positive HAMA assessment at any follow-up visit (Weeks 12 and 25; Months 12, 18, and 24).

Time frame: Day 1 to Day 730 (24 Months) after receiving the dosimetric dose

Number of Participants With Any Adverse Event (AE)

An AE was defined as any untoward medical occurrence in a participant administered a pharmaceutical product and does not necessarily have to have a causal relationship (association) with this treatment. Therefore, an AE was any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product, whether or not it was considered to be related to the medicinal product. Laboratory abnormalities were recorded as AEs only if they were associated with clinical sequelae and/or required an intervention.

Number of Participants With Any Infection at Week 16 Post-Fludarabine Treatment and Week 13 Post-TST Treatment Detected by Laboratory Culture of Participant Sample or Investigator Report

An infection is the colonization of a host organism by a parasite species. Infecting parasites seek to use the host's resources to reproduce, often resulting in disease. Colloquially, infections are usually considered to be caused by microscopic organisms or microparasites like viruses, bacteria, and viroids, although larger organisms such as macroparasites and fungi can also infect.

Number of the Indicated Type of Infection Reported by Investigator Based on Laboratory Testing at Week 16 Post-Fludarabine (Fl) Treatment and Week 13 Post-TST Treatment

An infection is the colonization of a host organism by a parasite species. Infecting parasites seek to use the host's resources to reproduce, often resulting in disease. Colloquially, infections are usually considered to be caused by microscopic organisms or microparasites like viruses, bacteria, and viroids, although larger organisms such as macroparasites and fungi can also infect.

Time frame: Week 16 Post-Fludarabine Treatment (Week -16 to Week 0); Week 13 Post-TST Treatment (Week 1 to Week 13)

Population: ITT-Exposed Population: all participants who received dosimetric and therapeutic doses and those who had an infection were evaluated. A single participant could have had more than one infection. The number analyzed in the category titles reflects the number of participants who had any infection.

Population: ITT-Exposed Population. 2 participants (par.) who received \<3 cycles of fludarabine (fl.) did not receive TST treatment and were not evaluated. Par. evaluable for response were those with \>=1 assessment. Three par. were not evaluable for response. None of the responses could be confirmed after fl. treatment; thus, no data are reported for this arm.

Number of Participants With the Investigator-assessed Unconfirmed Responses of Complete Response (CR), Clinical Complete Response (CCR), and Partial Response (PR)

CR: Complete resolution of disease-related (DR) radiological abnormalities; disappearance of non-Hodgkin's lymphoma-related signs/symptoms. CCR: Complete resolution of DR symptoms except for residual scar tissue. PR: 50% reduction in the sum of the products of the longest perpendicular diameters of measurable lesions with no new lesions.

Time frame: First day of fludarabine cycle 1 to day prior to TST/I 131 TST dosimetric dose (Week -16 to Week 1); Day of TST/I 131 TST dosimetric dose to database release (Week 1 to Week 520)

Population: ITT-Exposed Population. Participants (par.) evaluable for response were those with \>= 1 response assessment. 2 of 38 par. who received \<3 cycles of fludarabine withdrew from the study and were not evaluable for response. 35 of 38 par. received TST and I 131 TST treatment and were evaluated for response.

Time to Disease Progression or Death

Time to progression is the time from the treatment start date to the first documented disease progression or death. Disease progression: 50% increase from nadir of the sum of the longest perpendicular diameters of all measurable lesions or the appearance of any new lesion. Individual lesions must be \>2 cm in diameter per radiographic evaluation or \>1 cm in diameter by physical examination.

Time frame: First day of fludarabine cycle 1 to day prior to TST/I 131 TST dosimetric dose (Week -16 to Week 1); Day of TST/I 131 TST dosimetric dose to database release (Week 1 to Week 520)

Population: ITT-Exposed Population. Participants with disease progression were evaluated.
