Description:
Recently, the availability of R has substantially changed therapeutic approach to FL
patients, since its combination with chemotherapy has improved response rates, progression
free survival (PFS) and overall survival (OS). Based on the results of recently completed
randomized studies the standard treatment for patients with FL should consist of an initial
therapy with R-CHOP combination followed by two-year maintenance with R. Although results of
randomized trials confirmed that this approach results in an improved patients' outcome and
made a step forward in the management of patients with FL, one important question that can be
raised is if this approach is really needed for all patients with FL or if some of them could
benefit from a reduced intensity treatment achieving the same results in terms of outcome and
survival . This question is of particular interest for newly diagnosed patients for whom
maintenance does not affect OS.
More recent data demonstrated that the outcome of patients with FL can be further predicted
by evaluating the quality of response to therapy studying minimal residual disease (MRD).
This project addresses the objective of evaluating if combining clinical response assessed on
FDG-PET scan and molecular response measured through MRD detection could permit to single out
groups of patients at different risk of progression and to consequently modulate maintenance
therapies, with the aim to provide clinicians a more rational use of the available diagnostic
and therapeutic resources.

Detailed Description
This is a multicenter, randomized, phase III, superiority study comparing standard vs
response driven approach to maintenance. Adult patients (age ≥ 18 years) with naïve,
untreated follicular lymphoma, stage II-IV, Follicular Lymphoma International Prognostic
Index 2 (FLIPI2) >0 requiring a therapeutic intervention will be recruited and randomly
assigned in a 1:1 ratio to either standard or experimental arm.
All patients will receive the same induction therapy with 6 cycles of R-CHOP or
R-bendamustine and 2 additional doses of Rituximab.
At baseline patients will be assessed for molecular status and staged by means of CT scan. A
baselineFluorine-18-Fluorodeoxyglucose Positron Emission Tomography (FDG-PET) scan should
also be performed.
At the end of chemoimmunotherapy all patients will be assessed for disease response by common
clinical and laboratory examination, CT scan and FDG-PET. An intermediate assessment of
response with CT scan and FDG-PET (optional) will also be performed after the first four
courses of R-chemoimmunotherapy.
At the end of induction therapy the status of minimal residual disease will be also
evaluated.
After induction treatment all responding patients in the standard arm will receive standard
maintenance therapy with Rituximab (every 2 months for 2 years), while patients in the
experimental arm will be subdivided into two risk groups and assigned to different post
induction treatments based on FDG-PET and MRD results. In both arms, patients with stable or
progressive disease (PET positive and less than PR on CT scan) will be addressed to salvage
treatment chosen at physician discretion.
In the experimental arm, risk group allocation will be performed primarily on the basis of
FDG-PET results:
- Group 1 (low risk): negative FDG-PET
- Group 2 (high risk): positive FDG-PET
Patients at low risk (FDG-PET negative) will received maintenance therapy according to their
MRD status,particularly:
- Group 1a (MRD negative): observation
- Group 1b (MRD positive): pre-emptive Rituximab therapy
Patient at high risk (FDG-PET positive) will receive maintenance regardless of their MRD
status:
· Group 2: intensified maintenance ((90)Y Ibritumomab Tiuxetan + Rituximab maintenance )

Primary Outcome Measures
Measure: | PFS |
Time Frame: | 12/31/2019 |
Safety Issue: | |
Description: | To evaluate whether a FDG-PET and MRD response-based maintenance therapy is more effective in terms of Progression-Free Survival (PFS) than a standard maintenance therapy with Rituximab in patients with untreated, advanced, follicular lymphoma. Progression Free Survival (PFS) PFS will be measured from the date of randomization to the date of documented first occurrence of disease progression or relapse or to the date of death from any cause. Responding patients and patients who are lost to follow up will be censored at their last assessment date. |
Secondary Outcome Measures
Measure: | CRR |
Time Frame: | 12/31/2019 |
Safety Issue: | |
Description: | Complete Response Rate (CRR) is defined as the number of CR after the completion of the study treatment. Patients without a response assessment (due to any reasons) will be considered as non-responders. |
Measure: | ORR |
Time Frame: | 12/31/2019 |
Safety Issue: | |
Description: | Overall Response Rate (ORR) after the completion of the treatment, defined as the sum of Complete Response and Partial Response. Patients without a response assessment (due to any reasons) will be considered as non-responders. |
Measure: | DR |
Time Frame: | 12/31/2019 |
Safety Issue: | |
Description: | Duration of Response (DR) is from the time when criteria for response (ie, CR or PR) are met, to the first documentation of relapse or progression. |
Measure: | EFS |
Time Frame: | 12/31/2019 |
Safety Issue: | |
Description: | Event Free Survival (EFS) is measured from the time from study entry to any treatment failure including disease progression, or discontinuation of treatment for any reason (eg, disease progression, toxicity, patient preference, initiation of new treatment without documented progression, or death). |
Measure: | OS |
Time Frame: | 12/31/2019 |
Safety Issue: | |
Description: | Overall survival (OS) is defined as the time from the first day of study treatment until the date of death irrespective of cause. Patients who have not died at the time of end of the whole study , and patients who are lost to follow up , will be censored at the date of the last contact. |
Measure: | Molecular response analysis |
Time Frame: | 12/31/2019 |
Safety Issue: | |
Description: | Rate of molecular remission will be defined as the proportion of patients polymerase chain reaction (PCR) negative for Bcl2/IgH at different time-points including those achieving continuous MR in two or more consecutive time-points. Patients without a response assessment (due to any reasons) will be excluded from the analysis.
Rate of conversion will be defined as the proportion of patients from baseline PCR-positivity to PCR-negativity. Patients without a response assessment (due to any reasons) will be excluded from the analysis.
Rate of molecular relapse will be defined as the proportion of patients from PCR-negativity to PCR-positivity. Patients without a response assessment (due to any reasons) will be excluded from the analysis. |
