Bendamustine Hydrochloride and Rituximab with or without Bortezomib Followed by Rituximab with or without Lenalidomide in Treating Patients with High-Risk Stage II, Stage III, or Stage IV Follicular Lymphoma

  • Study type:

    Interventional What is this?

    Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
  • Study phase:

    II What is this?

    During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

RATIONALE: Drugs used in chemotherapy, such as bendamustine hydrochloride, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Biological therapies, such as lenalidomide, may stimulate the immune system in different ways and stop cancer cells from growing. It is not yet known whether giving bendamustine hydrochloride and rituximab together alone is more effective than giving bendamustine hydrochloride and rituximab together with bortezomib or lenalidomide in treating follicular lymphoma.

PURPOSE: This randomized phase II trial is studying giving bendamustine hydrochloride and rituximab together with or without bortezomib followed by rituximab with or without lenalidomide to see how well they work in treating patients with high-risk stage II, stage III, or stage IV follicular lymphoma.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

DISEASE CHARACTERISTICS:

  • Histologically confirmed (biopsy-proven) diagnosis of follicular B-cell non-Hodgkin lymphoma with no evidence of transformation to large cell histology
    • Patients having both diffuse and follicular architectural elements are eligible if the histology is predominantly follicular (i.e., ≥ 50% of the cross-sectional area) and there is no evidence of transformation to a large cell histology)
    • Diagnostic confirmation (i.e., core needle or excisional lymph node biopsy) required if the interval since tissue diagnosis of low-grade malignant lymphoma is > 24 months
      • Bone marrow biopsy alone not acceptable
  • Stage II, III, or IV AND grade 1, 2, or 3a disease
  • Must meet criteria for High Tumor Burden (higher risk) as defined by either the Groupe D'Etude des Lymphomes Follicularies (GELF) criteria OR the follicular lymphoma international prognostic index (FLIPI) as defined below:
    • Patient must meet ≥ 1 of the following GELF criteria:
      • Nodal or extranodal mass ≥ 7 cm
      • At least 3 nodal masses > 3.0 cm in diameter
      • Systemic symptoms due to lymphoma or B symptoms
      • Splenomegaly with spleen > 16 cm by CT scan
      • Evidence of compression syndrome (e.g., ureteral, orbital, gastrointestinal) or pleural or peritoneal serous effusion due to lymphoma (irrespective of cell content)
      • Leukemic presentation (≥ 5.0 x 10^9/L malignant circulating follicular cells)
      • Cytopenias (polymorphonuclear leukocytes < 1.0 X 10^9/L, hemoglobin < 10 g/dL, and/or platelets < 100 x 10^9/L)
    • Patient must have a FLIPI-1 score of 3, 4, or 5 (1 point per criterion below):
      • Age ≥ 60 years
      • Stage III-IV disease
      • Hemoglobin level < 12 g/dL
      • > 4 nodal areas
      • Serum LDH level above normal
  • At least 1 objective measurable disease parameter
    • Baseline measurements and evaluations (PET and CT) obtained within 6 weeks of randomization
    • Measurable disease in the liver is required if the liver is the only site of lymphoma
