E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the benefit of maintenance therapy with rituximab as measured by progression-free survival (PFS) in comparison with no maintenance therapy after induction of response with chemotherapy plus rituximab in patients with high tumor burden follicular lymphoma |
|
E.2.2 | Secondary objectives of the trial |
To evaluate event-free survival (EFS), overall survival (OS), time to next anti-lymphoma treatment (TTNLT), time to next chemotherapy treatment (TTNCT), response rates at the end of maintenance treatment, transformation rate at first relapse and quality of life for three different chemotherapy regimens combined with rituximab, with or without maintenance rituximab, for first line treatment of high tumor burden,
follicular lymphoma. To assess safety of rituximab maintenance therapy
over 2 years as measured by the incidence of toxicity. |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
The PRIMA study represents a unique opportunity to collect biological samples from patients with follicular lymphoma at diagnosis that can be used to improve comprehension of the disease, better define the prognostic criteria in follicular lymphoma and identify new factors that influence treatments results and outcome. These scientific studies will be performed as ancillary studies based on the PRIMA protocol. |
|
E.3 | Principal inclusion criteria |
Histologically confirmed follicular lymphoma grade 1, 2 or 3a (biopsy ≤ 4 months).
- Patients previously untreated.
- Bulky disease at study entry according to the GELF criteria:
- Age must be > 18 years.
- Performance status < 2 on the ECOG scale (see appendix E1).
- Adequate hematological function (unless those abnormalities are related to lymphoma extension) within 28 days prior to registration, including:
• Hemoglobin ≥ 8.0 g/dL (5.0 mmol/L)
• Absolute neutrophil count (ANC) ≥ 1.5 109/L
• Platelet count ≥ 100 109/L
- Women are not breast feeding, are using effective contraception, are not pregnant and agree not to become pregnant during participation in the trial and during the 12 months thereafter. Men agree not to father a child during participation in the trial and during the 12 months thereafter.
- Having previously signed a written informed consent form.
|
|
E.4 | Principal exclusion criteria |
- Transformation to high-grade lymphoma (secondary to “low-grade” follicular lymphoma).
- Grade 3b follicular lymphoma.
- Presence or history of CNS disease (either CNS lymphoma or lymphomatous meningitis).
- Patients regularly taking corticosteroids during the last 4 weeks, unless administered at a dose equivalent to < 20 mg/day prednisone.
- Patients with prior or concomitant malignancies except non-melanoma skin cancer or adequately treated in situ cervical cancer.
- Major surgery (excluding lymph node biopsy) within 28 days prior to registration.
- Poor renal function: Serum creatinine > 2.0 mg/dL (197 μmol/L),
- Poor hepatic function: total bilirubin > 2.0 mg/dL (34 μmol/L), AST (SGT) > 3 x the upper limit of normal unless these abnormalities are related to lymphoma.
- Known HIV infection or active HBV or HCV infection ≤ 4 weeks at registration.
- Serious underlying medical conditions, which could impair the ability of the patient to participate in the trial (e.g. ongoing infection, uncontrolled diabetes mellitus, gastric ulcers, active autoimmune disease). Judgment is up to the investigator.
- Life expectancy < 6 months
- Known sensitivity or allergy to murine products
- Treatment within a clinical trial within 30 days prior to trial entry
- Any other co-existing medical or psychological condition that will preclude participation in the study or compromise ability to give informed consent.

E.5 End points |
E.5.1 | Primary end point(s) |
Progression-free survival (PFS) |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
PFS will be measured from the day of randomization to the date of first documented disease progression, relapse or death from any cause. Responding patients and patients who are lost to follow up will be censored at their last tumor assessment date. |
|
E.5.2 | Secondary end point(s) |
Event-free Survival (EFS)
Event-free survival will be measured from the date of randomization to the date of first documented progression, relapse, initiation of a new anti-lymphoma treatment or death by any cause. Responding patients and patients who are lost to follow up will be censored at their last tumor assessment date.
Time To Next Anti-Lymphoma Treatment (TTNLT)
Time to next anti-lymphoma treatment will be measured from the date of randomization to the date of first documented administration of any new anti-lymphoma treatment (chemotherapy, radiotherapy, radioimmunotherapy, immunotherapy). Patients continuing in response or who are lost to follow-up will be censored on their last visit date. Patients who died (due to any cause) before having received a new anti-lymphoma treatment will be included in the statistical analysis with death being counted as an event.
Time to next Chemotherapy Treatment (TTNCT)
Time to next chemotherapy treatment will be measured from the date of randomization to the date of first documented administration of new chemotherapy or new cytotoxic agent. For any given patient, the TTNCT may be the same as TTNLT. Patients continuing in response or who are lost to follow-up will be censored on their last visit date. Patients who died (due to any cause) before having received a new chemotherapy treatment will be included in the statistical analysis with death being counted as an event.
Overall Survival
Overall survival will be determined from the date of randomization to the date of death regardless of cause. Patients who have not died at the time of the analysis (clinical cut-off) will be censored at the date of the last contact. If a patient was not assessed for survival within the last 3 months prior to the analysis an assessment within the next month is required.
Overall Response Rate at the End of Maintenance Treatment
Response rates will be assessed at the end of the 2 years maintenance treatment phase by the investigator. Assessment of response will be based on the International Workshop to Standardize Response Criteria for NHL (Criteria for evaluation of response in Non-Hodgkin’s lymphoma Cheson, 1999). A patient is defined as a responder if he has a complete response (CR/Cru) or partial response (PR) after the end of the maintenance treatment.
Patients without response assessment (due to whatever reason) will be considered as non-responders.
Transformation Rate at First Progression
Histological transformation rate at first progression is defined by the appearance of diffuse areas of large lymphoma cells within a tumor site. For this purpose, a biopsy or a cytological examination should be obtained at progression, if possible. This material should be available for central pathological review. This analysis will be restricted to patients with a biopsy at first progression.
Quality of Life Analysis
QoL scale measurements using the FACT-G and QLQ-C30 questionnaires collected over time will be compared for patients receiving rituximab maintenance and those in the observation arm. |
