About this study

Official title: A Study of 131I-Tositumomab (Bexxar®) Consolidation in Patients With B-Cell Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma in First Remission

This phase II trial studies how well tositumomab and iodine I 131 tositumomab works in treating patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) that have had their first decrease in or disappearance of signs and symptoms of cancer (first remission). Monoclonal antibodies, such as tositumomab and iodine I 131 tositumomab, may block cancer growth in different ways by targeting certain cells.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To estimate the progression-free survival at 2 years following administration of 131I-tositumomab (tositumomab and iodine I 131 tositumomab) in patients with CLL/SLL who achieve a complete remission (CR) or partial remission (PR) with prior therapy.

II. To improve the response rate by administering 131I-tositumomab to patients who have achieved a PR not a CR after any prior therapy.

III. To eliminate residual disease (documented by flow cytometry or polymerase chain reaction [PCR]) using 131I-tositumomab in patients who have achieved a CR after any prior therapy.

SECONDARY OBJECTIVES:

  1. To evaluate the toxicities of 131I-tositumomab in 1st remission patients with previously treated CLL/SLL.

OUTLINE:

Patients receive tositumomab and iodine I 131 tositumomab intravenously (IV) over 90 minutes on day 0 and then again 7-14 days later over 30-60 minutes.

After completion of study treatment, patients are followed up weekly for 3 months, every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Probability of Progression-free Survival (PFS)

    Progression free survival (PFS) is defined as the interval between the first treatment day to the first sign of disease progression. This outcome measures the percentage of participants with PFS at 36 months.

    Measured: 36 months

  2. Improved Response Rate After Treatment With 131I-tositumomab for Patients Who Had Evidence of CLL at the End of Initial Chemotherapy

    Response rates determined using National Cancer Institute (NCI) working group guidelines plus computed tomography (CT) scan criteria. Participants were assessed for response after initial chemotherapy and again 3 months after 131I-tositumomab treatment.Only patients who had less than a complete response (CR) after initial chemotherapy were assessed for improved response after 131I-tositumomab.

    Measured: 3 months after 131I-tositumomab consolidation

  3. Minimal Residual Disease (MRD) by Flow Cytometry or Polymerase Chain Reaction (PCR) in Patients Who Had a Complete Remission (CR) After Any Prior Therapy

    Measured: 3 months after 131I-tositumomab consolidation

Secondary outcomes (1)

  1. Evaluate Toxicities of 131I-tositumomab

    Adverse events following treatment of 131I-tositumomab

    Measured: 48 months (median)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Tositumomab and Iodine I 131 Tositumomab in people with Lymphoid Leukemia in Remission and Stage I Chronic Lymphocytic Leukemia, run by Fred Hutchinson Cancer Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 13 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Oct 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 12 Oct 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Probability of Progression-free Survival (PFS) (time frame: 36 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00476047.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Oct 2017.
