This applies for the time period between signing of the informed consent form and 12 months after last rituximab dose or 18 months after last obinutuzumab dose. A woman is considered of childbearing potential, i.e. fertile, following menarche and until becoming postmenopausal unless permanently sterile. Permanent sterilization methods include but are not limited to hysterectomy, bilateral salpingectomy and bilateral oophorectomy. A postmenopausal state is defined as no menses for continuous 12 months without an alternative medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a postmenopausal state in women not using hormonal contraception or hormonal replacement therapy. The investigator or a designated associate is requested to advise the patient how to achieve highly effective birth control (failure rate of less than 1%) e.g., intrauterine device (IUD), intrauterine hormone-releasing system (IUS), bilateral tubal occlusion, vasectomized partner. The use of condoms by male patients is required (even if surgically sterilized, i.e., status post vasectomy) unless the female partner is permanently sterile. Full sexual abstinence is admitted when this is in line with the preferred and usual lifestyle of the subject, for the same time period planned for other methods of birth control (see above). Periodic abstinence (e.g., calendar, ovulation, symptothermal, post ovulation methods for the female partner) and withdrawal are not acceptable methods of contraception).

About this study

Official title: Shortened vs Standard Chemotherapy Combined With Immunotherapy for the Initial Treatment of Patients With High Tumor Burden Follicular Lymphoma. A Randomized, Open Label, Phase III Study by Fondazione Italiana Linfomi.

FIL_FOLL19 is an open-label, multicenter, randomized phase III trial. The sponsor of this clinical trial is Fondazione Italiana Linfomi (FIL).

The Primary Objective of the study is to demonstrate that, in patients with newly diagnosed, advanced stage Follicular Lymphoma (FL) with high tumor burden according to the Groupe d'Etude des Lymphomes Folliculaires (GELF) criteria, a treatment strategy that reduces the number of chemotherapy cycles in case of early response to immunochemotherapy is not inferior compared to standard therapy at full dose in terms of Progression-Free Survival (PFS).

Read the detailed description

This is an open-label, multicenter, randomized phase III trial. The study plans to randomize patients with a 1:1 ratio to Arm A (Standard arm) or Arm B (Experimental arm).

Once randomized, each patient will start immunochemotherapy with one of the approved regimens (R-CHOP, R-Bendamustine, G-CHOP, G-Bendamustine, G-CVP) chosen by the physician on a patient basis before randomization.

Patients randomized to Arm A will receive an induction immunochemotherapy at full doses (standard schedule).

After cycle 4, patients will be assessed for response and will complete their planned therapy if at least a stable disease is confirmed.

Patients randomized to Arm B will start their induction treatment with 4 cycles of the immunochemotherapy standard dose chosen by the physician: after cycle 4, patients will be assessed for response and will proceed with subsequent treatment based on the quality of their response.

Specifically:

  • Patients achieving a Complete Remission (CR) will receive a shortened treatment: in detail, they won't receive any further chemotherapy but will complete induction with 4 additional cycles of only the Monoclonal Antibody (MoAb) given during the first four cycles (in case of G-bendamustine, 2 additional cycles of obinutuzumab);
  • In case if response less than Complete Remission (CR), Partial Remission (PR) or Stable Disease (SD), patients will complete treatment as planned for patients in Arm A.

In both arms, at the end of induction responding patients (CR, PR) will be addressed to a standard anti-CD20 maintenance (1 dose every 8 weeks for two years) with the same Monoclonal Antibody (MoAb) given during induction.

Patients with progressive disease at any time (regardless of treatment arm) will be addressed to salvage therapy.

The study plans the evaluation of quality of life by collecting the Patient-Reported Outcome(s) (PROs) through the Functional Assessment of Cancer Treatment-Lymphoma (FACT-Lym questionnaire) at predetermined timepoints during the study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Progression Free Survival (PFS)

    The length of time during and after the treatment that patients live with the disease, but it does not get worse. Progression-Free Survival (PFS) will be measured from the time of study entry to documented progression or to the patient's death as a result of any causes. Subjects with incomplete follow-up or with no disease evaluation will be censored at the date of last available documented status of freedom from failure.

    Measured: The endpoint will be assessed from the beginning of the study up to 104 months (end of study)

Secondary outcomes (7)

  1. Overall Survival (OS)

    Overall Survival, the percentage of patients alive, will be measured from the time of study entry to death from any cause. Patients who have not died at the time of the final analysis will be censored at the date of the last contact.

    Measured: The endpoint will be assessed from the beginning of the study up to 104 months (end of study)

  2. Event-Free Survival (EFS)

    The measure of time after treatment that patients have not have cancer come back or get worse. It will be measured from the time of study entry to any treatment failure, including disease progression, or discontinuation of treatment for any reason (e.g., disease progression, toxicity, patient preference, initiation of a new treatment without documented progression) or death from any cause.

    Measured: The endpoint will be assessed from the beginning of the study up to 104 months (end of study)

  3. Overall Response rate (ORR)

    Overall response rate (ORR) is defined as the proportion of patients who have a partial or complete response to therapy; It will be defined according to Response Criteria for Non-Hodgkin Lymphoma (NHL) with Positron Emission Tomography (PET) (Lugano 2014). ORR will include the sum of patients in Complete Remission and Partial Remission (CR + PR). It will be evaluated on assessed patients and on all treated patients, considering patients without a response assessment (due to any reason) as non-responders.

    The best overall response will be defined as the best response between the date of beginning of therapy and the last restaging.

    Measured: The endpoint will be assessed from the beginning of the study up to 104 months (end of study)

  4. Complete response rate (CRR)

    The Complete Response Rate is defined as the percentage of patient in Complete Remission. It will be defined according to Response Criteria for Non-Hodgkin Lymphoma (NHL) with Positron Emission Tomography (PET) (Lugano 2014). CRR will include only patients in Complete Remission (CR). It will be evaluated on assessed patients and on all treated patients, considering patients without a response assessment (due to any reason) as non-responders.

    Measured: The endpoint will be assessed from the beginning of the study up to 104 months (end of study)

  5. Molecular response

    Molecular response assessed by means of the evaluation of the Bcl2/IgH rearrangement at baseline and of the Minimal Residual Disease (MRD) at subsequent defined timepoints.

    Measured: The endpoint will be assessed from the beginning of the study up to 104 months (end of study)

  6. Incidence of toxicities (Safety of the treatment)

    Safety of the treatment according to the current version of the CTCAE. Incidence of toxicities

    Measured: The endpoint will be assessed from the beginning of the study up to 104 months (end of study)

  7. Patient-Reported Outcomes (PROs)

    Health Related Quality of Life (HR-QoL) will be evaluated by means of Patient-Reported Outcome(s) PROs. Patients will be asked to complete the Functional Assessment of Cancer Therapy - Lymphoma (FACT-Lym) questionnaire at prespecified points during the study. The questionnaire results will be analyzed according to recommendations of the instrument scoring procedures.

    Measured: The endpoint will be assessed from the beginning of the study up to 104 months (end of study)

Model description
This is a prospective, multicenter, phase III, two arms randomized trial with a non-inferiority design with Progression-Free Survival (PFS) as primary endpoint. Patients who meet all eligibility criteria will be centrally randomized to one of the two treatment arms in a 1:1 ratio, using random sequences blocks of variable size. The web-based allocation process, completely concealed to researchers, will be stratified according Follicular Lymphoma International Prognostic Index 2 (FLIPI2) score (0-2, 3-5), chemotherapy regimen (CHOP, Bendamustine, CVP) and anti-CD20 Monoclonal Antibody (MoAb) (rituximab, obinutuzumab). A non-inferiority design has been adopted to demonstrate that a shortened exposure to chemotherapy in patients responding to the first four cycles of immunochemotherapy is not detrimental in terms of PFS compared to full dose standard treatment. The primary comparison will be done as an Intention To Treat (ITT) analysis including all randomized patients.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Immunochemotherapy regimen: Rituximab-bendamustine (Arm A), Immunochemotherapy regimen: Rituximab-bendamustine (Arm B) and Immunochemotherapy regimen: R-CHOP (Arm A) in people with Follicular Lymphoma, run by Fondazione Italiana Linfomi - ETS at 54 sites in Italy.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 29 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 26 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 54 sites in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Progression Free Survival (PFS) (time frame: The endpoint will be assessed from the beginning of the study up to 104 months (end of study)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05058404.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Jun 2026.
