Brief summary
This is a Phase III, multicenter, open-label, randomized and controlled study to compare the efficacy of a consolidation therapy with RIT versus ASCT in patients with FL in CR or PR after second or third line chemotherapy supplemented with rituximab.
Detailed description
This is a Phase III, multicenter, open-label, randomized and controlled study to compare the efficacy of a consolidation therapy with RIT vs. ASCT in patients with FL in CR or PR after second or third line chemotherapy supplemented with rituximab. Patients with FL will be eligible for screening at the time of relapsed or refractory disease after two or less chemotherapy lines at least one containing rituximab. This study will be conducted in six steps as follows. Screening Phase, Enrolment and Induction chemotherapy (STEP I) Randomization (STEP II) Stem cell mobilization and collection (STEP III) Consolidation (RIT vs ASCT) (STEP IV) Maintenance (STEP V) Follow-up Phase (STEP VI)
Interventions
Infusion of 90Y Ibritumomab Tiuxetan if the patient has less than 25% BM infiltration at the pre-consolidation restaging (0.4 mCi/kg if platelets ≥150,000/mmc, 0.3 mCi/kg if platelets are between 100.000 and 150,000/mmc).
BEAM REGIMEN day -6 Carmustine\* 300 mg/ m2 i.v. in 250ml dextrose 5% solution from day -5 to day -2 Cytarabine 200 mg/m2 i.v. every 12 hours in 250 ml dextrose 5% solution, 250 ml/hr Etoposide 100 mg/m2 i.v. every 12 hours in 250 ml dextrose 5% solution, 250 ml/hr day -1 Melphalan 140 mg/m2 i.v. in 100ml saline solution in 200 ml/hr day 0 UReinfusion of autologous stem cells following this rules: 1. Patient collecting ≥6x106 CD34+ cells/kg use \>4x106 CD34+ cells/kg for ASCT and keep \>2x106 CD34+ cells/kg for back up; 2. Patient collecting 4-6x106 CD34+ cells/kg use \>2x106 CD34+ cells/kg for ASCT and keep \>2x106 CD34+ cells/kg for back up; 3. Patient collecting 2-4x106 CD34+ cells/kg use all CD34+ cells for ASCT and keep no back up. day 2 Filgrastim or Lenograstim 5μg/Kg s.c. until ANC \> 1500/mmc

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Progression Free Survival from randomization (rPFS) | 36 months | PFS will be defined as the time between the date of randomization and the date of disease progression, relapse or death from any cause. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Overall Survival from randomization (rOS) | 36 months | OS will be defined as the time between the date of randomization and the date of death from any cause. |
| Event Free Survival (EFS) | 36 months | EFS will be measured from the date of randomization to the date of any treatment failure including death, disease progression or relapse, discontinuation of treatment for any reason (toxicity, patient preference, initiation of new treatment without documented progression). |
| Treatment Free Survival from randomization (TFS) | 36 months | TFS will be defined as the time between the date of the end of primary treatment until the institution of the next unplanned chemotherapy in randomized population. |
| Progression Free Survival from enrolment (ePFS) | 42 months | PFS will be defined as the time between the date of enrolment and the date of disease progression, relapse or death from any cause. |
| Overall Survival from enrolment (eOS) | 42 months | OS will be defined as the time between the date of enrolment and the date of death from any cause |
| Complete Response (CR) Rate | At the end of the consolidation phase (6 months) | Proportion of CR according to the Cheson 2007 response criteria at the end of consolidation phase. |
| Overall Response Rate (ORR) | At the end of the consolidation phase (6 months) | ORR at the end of the consolidation phase is defined as Complete Response (CR) or Partial Response according to the Cheson 2007 response criteria. |
| Toxicity | 42 months | Incidence of grade 3 or higher Toxicity measured by CTCAE v.4.03 during therapy. |
| Molecular Response rate (MR) | 36 months | Rate of MR will be defined as the proportion of patients achieving PCR negativity after the consolidation phase and during follow up. |
| Molecular Response rate conversion (cMR) | 6 months | Rate of conversion will be defined as the proportion of patients with baseline PCR-positivity converting to PCR-negativity during treatment. |
| Molecular Relapse Rate (MRR) | 24 months | Rate of molecular relapse will be defined as the proportion of patients with PCR-negativity after treatment converting to PCR-positivity during the first two years of follow-up. |
