Study Details

Study Description

Brief Summary

The purpose of this study is to determine the rate and duration of complete remission and molecular response in patients with relapsed/refractory follicular lymphoma, using a combined treatment with rituximab plus chemotherapy followed by in vivo purged peripheral blood stem cells (PBSC) mobilization and autotransplant.

Condition or Disease Intervention/Treatment Phase
  • Procedure: Immunochemotherapy, in vivo purging and autrotransplant
Phase 2

Detailed Description

Autologous stem cell transplantation has been shown effective in the long-term control of follicular lymphoma. Lymphoma, however, can progress after high-dose treatments. Lymphoma cells have been proved to contaminate bone marrow and peripheral blood stem cells (PBSC) collections and may contribute to relapse after autotransplant. The presence in peripheral blood and marrow of PCR-detectable cells bearing the bcl-2 rearrangement appeared to be a surrogate marker of disease and the achievement of a bcl-2 negative status is associated with a lower risk of recurrence. Several methods have been attempted to abolish graft contamination: in vitro treatment with cytotoxic agents, in vitro treatment with anti-B-cell monoclonal antibodies and complement, immunomagnetic beads, positive selection of CD34+ cells. All these techniques usually produce loss of cells, are time-consuming and expensive, and neoplastic depletion is often partial with residual polymerase chain reaction (PCR)-positive cells in the graft.

In the last years the chimeric anti-CD20 monoclonal antibody Rituximab has been shown to be an effective therapeutic option for low-grade lymphoma. Owing to the different mechanism of action, the synergism with cytotoxic agents, and the non-overlapping toxicity, Rituximab is an ideal drug for combination with chemotherapy. On this basis, Rituximab has been used during mobilisation procedures as a tool to obtain in vivo purging and collection of lymphoma-free progenitor cells. In addition, several studies have demonstrated that the efficiency of peripheral blood stem cells (PBSC) harvested is not adversely affected by Rituximab and that engraftment and all parameters of hematopoietic recovery are not compromised. The incorporation of Rituximab into sequential high-dose therapy programs produced high rates of clinical and molecular remission in patients with indolent lymphoma, indicating that the antibody has an additive effect on chemotherapy.

Arms and Interventions

Arm Intervention/Treatment
Experimental: In vivo purging autotransplant

Procedure: Immunochemotherapy, in vivo purging and autrotransplant
2-4 courses every 3 weeks with rituximab 375 mg/m^2 on day 1, vincristine 1.4 mg/m^2 on day 2 and cyclophosphamide 400 mg/m^2 on days 2-6. Courses were started if granulocytes >1.5 · 10^9/l. The phase of peripheral blood stem cells (PBSC) mobilization coupled rituximab 375 mg/m^2 on days 1 and 9 with high-dose cytarabine (AraC) 2 g/m^2 every 12 hours on days 2 and 3. Granulocyte colony-stimulating factor (G-CSF)(5 mcg/kg/day subcutaneously) was administered from day 6. High-dose chemotherapy with autotransplant consisted of BEAM [carmustine (BCNU), etoposide, Cytarabine (AraC), melphalan] followed by the infusion of in vivo purged peripheral blood stem cells (PBSC) + 2 consolidation doses of rituximab 375 mg/m^2 on days +14 and +21 after autotransplant.

Outcome Measures

Primary Outcome Measures

  1. Progression-free Survival [every 3 months for the first year after autotransplant and every 6 months after the first year of follow up]

    PFS is calculated according to the Kaplan-Meier estimator. The observation time of each subject is defined as the time from entry into the study until lymphoma progression or death as a result of any cause whichever occurs first. The 5-year PFS is the estimated cumulative probability of surviving at least 5 years without progression.
