Blood Stem Cell Transplant With Low Dose Chemotherapy for Relapsed Follicular Non-Hodgkin's Lymphoma (BMT CTN 0701)

Medical College of Wisconsin65 enrolled

Overview

Blood stem cell transplants are one treatment option for people with lymphoma or other types of blood cancers. For this type of treatment, family members or unrelated donors with a similar tissue type usually donate their blood stem cells to the transplant patients. This study will evaluate the effectiveness of a type of blood stem cell transplant that uses lower doses of chemotherapy in people with relapsed follicular non-Hodgkin's lymphoma (NHL).

Follicular NHL, a type of blood cancer, is the second most common type of non-Hodgkin's lymphoma, with approximately 15,000 new cases being diagnosed each year in the United States. Chemotherapy is a common treatment option for people with NHL, and at first most people achieve cancer remission with initial chemotherapy. However, after the initial chemotherapy, people with this disease typically experience a continuous pattern of relapse that results in progressively shorter remission durations. A blood stem cell transplant is another treatment option for people with follicular NHL. In a blood stem cell transplant procedure, healthy blood stem cells are taken from a donor and transplanted into the patient. The cells can be donated by a family member or an unrelated donor who has a similar tissue type. Typically, people who are undergoing a blood stem cell transplant receive high doses of chemotherapy before the transplant to prepare their bodies to accept the donor stem cells. In this study, participants will undergo a type of stem cell transplant called a nonmyeloablative transplant, which involves a reduced intensity method of transplantation that does not require high doses of chemotherapy. The purpose of the study is to examine the effectiveness of a nonmyeloablative allogeneic blood stem cell transplant at improving survival rates in people with relapsed follicular NHL. This study will enroll people with relapsed follicular NHL. At a baseline study visit, participants will undergo a medical history review, physical examination, blood collection, lung function testing, computed tomography (CT) scans, a bone marrow biopsy, and questionnaires to assess quality of life. Participants will be admitted to the hospital and on various days in the 2 weeks before the transplant, they will receive fludarabine, cyclophosphamide, rituximab, which are cancer medications, and tacrolimus, a medication that will help prevent graft-versus-host disease (GVHD), which is an attack by the donor cells on the body's normal tissues. Participants will then undergo the blood stem cell transplant. At various times during the 2 weeks after the transplant, participants will receive rituximab and methotrexate, which is another medication to prevent GVHD. They will also receive tacrolimus for at least 6 months to help prevent GVHD. Participants will remain in the hospital for as long as necessary to recover from the transplant. Follow-up study visits will occur weekly for Weeks 1 to 14, and then at Months 6, 12, 18, and 24. At each study visit, select baseline procedures will be repeated.

Patients in second or subsequent complete remission (CR) 2. Patients in first or subsequent partial remission (PR) 3. Patients experiencing a relapse that demonstrates a response, as defined as largest nodal mass less than or equal to 3 cm or greater than or equal to 50% reduction in estimated lymph node volume measured as a product of bi-dimensional measurements (see protocol for detailed definition). 4. Patients with stable follicular lymphoma are eligible if all lymph node masses are less than or equal to 3 cm and are smaller or unchanged in size to the most recent salvage regimen. * Patients with human leukocyte antigen (HLA)-matched donors that meet the following criteria: 1. 6/6 HLA-matched related donor. HLA typing must be performed by DNA methods for HLA-A and B at intermediate (or higher) resolution, and DRB1 at high resolution. The donor must be willing to donate peripheral blood stem cells and meet institutional criteria for stem cell donation. The donor must be medically eligible to donate stem cells according to individual transplant center criteria; or, 2. 8/8 HLA-matched unrelated donor. HLA typing must be performed by DNA methods for HLA-A, B, C, and DRB1 at high resolution. The donor must be willing to donate peripheral blood stem cells and meet National Marrow Donor Program (NMDP) criteria for stem cell donation. The donor must be medically eligible to donate stem cells according to NMDP criteria. * Patients with adequate organ function, as measured by the following: 1. Heart: Left ventricular ejection fraction at rest greater than 45% 2.

Outcomes

Primary Outcomes

Progression-Free Survival (PFS)

Patients are considered a failure for this endpoint if they die, or if they relapse/progress or receive anti-lymphoma therapy not including planned post-transplant radiation.

Time frame: Year 2

Secondary Outcomes

Graft Failure

Primary graft failure is defined as a donor peripheral blood T cell chimerism \< 5% at Day +30 post-transplant. Secondary Graft Failure is defined as documented engraftment followed by loss of graft as defined by donor peripheral blood T cell chimerism \< 5%.

Time frame: Day 30

Donor Cell Engraftment

Donor engraftment is defined as \> 5% donor peripheral blood T cell chimerism by Day +30 post-transplant in the setting of Absolute Neutrophil Count (ANC) recovery (ANC \>500/mm\^3 for 3 consecutive days).

Time frame: Days 30 and 100

Time to Neutrophil Recovery

Neutrophil Recovery is defined as ANC \> 500/mm\^3 for 3 consecutive days.

Time frame: Day 60

Acute Graft-versus-Host Disease (GVHD)

The event is the incidence of grades II-IV acute GVHD from day of transplant, where grade IV is worst. The first day of acute GVHD onset at a certain grade will be used to calculate a cumulative incidence curve for that acute GVHD grade. GVHD should be monitored in accordance with BMT CTN manual of procedures guidelines. Acute GVHD grading was based on the consensus conference criteria (Przepiorka, et. al., 1994) and the Center for International Blood and Marrow Transplant Research (CIBMTR) grading criteria.

Time frame: Day 100

Chronic GVHD

The event is the incidence and severity of chronic GVHD from day of transplant, a cumulative incidence curve will be computed along with a 95% confidence interval at two years post-transplant. Death prior to occurrence of chronic GVHD will be considered as a competing risk.
