Bendamustine and Rituximab Followed by 90-yttrium (Y) Ibritumomab Tiuxetan for Untreated Follicular Lymphoma

Completed · Phase 2

Conditions studied: Lymphoma, Follicular

In brief

The purpose of the study is to learn about the safety and effectiveness of treating follicular lymphoma with bendamustine and rituximab followed by radioimmunotherapy (RIT) using 90-yttrium (Y) ibritumomab tiuxetan. The researchers will also test blood and bone marrow for the BCL2 gene-Jh that is a commonly found in people with follicular lymphoma (FL) and look at how the BCL2 gene-Jh responds to the study treatment. Bendamustine is approved by the United States Food and Drug Administration (FDA) for the treatment of chronic lymphocytic leukemia and indolent B-cell non-Hodgkin's lymphoma (NHL) that has progressed during or within six months of treatment with rituximab or a rituximab-containing treatment regimen. Bendamustine is not approved by the FDA to treat follicular lymphoma. Rituximab is approved by the FDA for the treatment of relapsed or refractory, low-grade or follicular, CD20-positive B-cell non-Hodgkin's lymphoma. 90-yttrium (Y) ibritumomab tiuxetan is approved by the FDA for the treatment of relapsed or refractory, low-grade or follicular B-cell NHL, including rituximab refractory follicular NHL. It is also approved for the treatment of follicular NHL that is previously untreated with radioimmunotherapy and that achieved a partial or complete response to first-line chemotherapy. Study participants will will receive bendamustine and rituximab for up to 16 weeks. If participants' cancer responds well to the treatment with bendamustine and rituximab, they will receive up to 12 weeks of radioimmunotherapy (RIT). After the RIT is complete, participants will be asked to return to the clinic every 3 months for a maximum of 10 years for follow-up visits.

Female subjects of childbearing potential must have a negative pregnancy test (urine or serum b-HCG) at screening and within 1 week prior to the start of treatment with Y-90 ibritumomab tiuxetan
Voluntary written informed consent must be given before performance of any study-related procedure

You may not qualify if…

Prior chemotherapy, immunotherapy, or monoclonal antibody therapy
Receiving any other investigational agents
Primary CNS lymphoma
Known HIV
Treatment with therapeutic doses of systemic steroids within 4 weeks of beginning study treatment (cycle 1, day -7); topical use of corticosteroids and systemic replacement of corticosteroids for adrenal insufficiency are allowed
Malignant pleural, pericardial or peritoneal effusions
Known history of myelodysplastic syndrome (MDS) or found to have MDS
Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would, in the judgment of the investigator, limit compliance with study requirements
Pregnant or lactating female subjects
Concurrent active malignancy other than lymphoma or history of invasive malignancy within the past 5 years, except completely excised, non-melanoma skin cancer
Known Hepatitis B and/or Hepatitis C Infection
Any other condition, that in the judgment of the investigator places the patient at unacceptable risk if he/she were to participant in the study
