Trial summary

Patients with B-cell lymphoma who relapse after autologous transplant tend to have a poor prognosis. Currently, there is no standard treatment for such patients. Bexxar is a radioactive antibody therapy that has shown a 60-80% response rate in non-transplanted patients with relapsed B-cell lymphoma. Read more about this study

About this study

Official title: A Phase I Study of Bexxar® (Tositumomab and 131I-Tositumomab) Radioimmunotherapy in Patients With Relapsed or Residual CD20 Antigen-Expressing B-Cell Lymphomas Following Autologous Hematopoietic Stem Cell Transplantation

Patients with B-cell lymphoma who relapse after autologous transplant tend to have a poor prognosis. Currently, there is no standard treatment for such patients. Bexxar is a radioactive antibody therapy that has shown a 60-80% response rate in non-transplanted patients with relapsed B-cell lymphoma. This study will test the safety and efficacy of Bexxar in the treatment of patients whose B-cell lymphoma has relapsed after an autologous transplant.

Read the detailed description

High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) has become the standard of care for relapsed/refractory chemotherapy-sensitive non-Hodgkin's lymphomas (NHL). However, one-half to two-thirds of such patients will relapse after ASCT, with subsequent poor prognosis, and new therapies are urgently needed for this patient population. Radioimmunotherapy (RIT) as a single agent therapy in patients with CD20 antigen-expressing relapsed or refractory low-grade, follicular, or transformed NHL has demonstrated overall response rates of 60-80% and has been approved by the FDA for use in this setting. While RIT is currently under investigation as a component of conditioning regimens for ASCT, the safety and efficacy of RIT after ASCT has not yet been well described. We will conduct a single-center Phase I dose-escalation trial of Bexxar (Tositumomab and 131I Tositumomab) for treatment of relapsed or residual CD20 antigen-expressing B-cell lymphomas following ASCT. Our primary aim will be to determine the safety, dose-limiting toxicity, and maximum tolerated dose of Bexxar in this post-ASCT patient population. Our secondary aim will be to describe the overall response rate, progression-free survival, time to treatment failure, and overall survival. Should Bexxar prove to be safe in this population, subsequent trials will be designed to investigate further the efficacy of RIT in the post-transplant setting.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • BexxarDrug

    Day 0: Tositumomab, IV (in the vein) followed by test dose of 131I-Tositumomab, IV (in the vein) to determine treatment dose of 131I-Tositumomab.

    1-2 weeks after Day 0: Tositumomab, IV (in the vein) followed by therapeutic dose 131I-Tositumomab (in the vein).

What is being measured

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

  1. dose-limiting toxicity

    Measured: Week 7 after Bexxar

  2. maximum tolerated dose

    Measured: Week 7 after Bexxar

Secondary outcomes (3)

  1. overall response rate

    Measured: Week 13 after Bexxar

  2. progression-free survival

    Measured: 5 years after Bexxar

  3. time to treatment failure

    Measured: 5 years after Bexxar

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Bexxar in people with B-cell Lymphoma and Non-Hodgkin's Lymphoma, run by University of Pennsylvania 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 10 inclusion and 8 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 17 Aug 2016. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

dose-limiting toxicity (time frame: Week 7 after Bexxar). The study lists 2 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 NCT00434629.

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 17 Aug 2016.
