Outcome Measures

Primary Outcomes (1)

  • Response Rate

    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.

    Week 26

Secondary Outcomes (7)

  • 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

  • +2 more secondary outcomes

Study Arms (1)

Arm 1

EXPERIMENTAL

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.

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients must have evidence of persistent or progressive follicular grade, 1, 2 or 3 or marginal zone B-cell non-Hodgkin's lymphoma.
  • Must have received at least two prior courses of systemic treatment including at least one treatment of rituximab (lymphoma must not have progressed during their most recent systemic chemotherapy treatment).
  • Must have evidence that their lymphoma expresses CD20 antigen and have adequate renal and hepatic function.

You may not qualify if:

  • Received chemotherapy, radiation therapy, immunosuppressants or cytokine treatment within 4 weeks prior to study entry.
  • Have active obstructive hydronephrosis.
  • Had prior autologous hematopoietic stem cell transplant or any allogenic stem cell transplant.
  • Have active infection requiring IV antibiotics.
  • Have brain or leptomeningeal metastasis.
  • Had previous allergic reaction to iodine, previously received radioimmunotherapy or are currently receiving approved or experimental anti-cancer drugs.
  • Patients who are pregnant or breast feeding, have known HIV infection, or are Human anti-murine antibody (HAMA) positive.
  • Other criteria will be evaluated at the screening visit.
