Follicular Lymphoma
Conditions
Keywords
LNH, CD20+, follicular
Brief summary
Patient will receive either one infusion of rituximab IV and seven administrations of rituximab SC (experimental arm) or four infusions of rituximab IV (standard arm). The hypothesis is that the use of rituximab by sub cutaneous route and the scheme of administration could: * optimize rituximab exposure leading to improve response rate * increase adaptative response and then improve long-term control disease.
Interventions
intra-venous, 375 mg/m²
sub-cutaneous, 1400 mg

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Progression Free Survival (PFS) | 5.5 years | Time from randomization into the study to the first observation of documented disease progression or death due to any cause. If a subject has not progressed or died, PFS will be censored at the time of last visit with adequate assessment |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Response Rates | M3 and M12 | Disease response evaluation, assessment will be based on the International Workshop to Standardize Response criteria for NHL (Criteria for evaluation of response in Non-Hodgkin's lymphoma) according to Cheson 1999 (M3 and M12) and according to Cheson 2014 (M12 only). The response rates will be described for each modality (CR, CRu, PR, SD and PD) and the Overall response rates (CR+CRu+PR) will also be described at the two time points (M3 & M12). |
| Overall Survival (OS) | 5.5 years | time from the date of randomization to the date of death from any cause. Alive patients will be censored at their last follow-up date. |
| Best Response Rate during the study | M3 and M12 | Best disease response, 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)). The response rates will be described for each modality (CR, CRu, PR, SD and PD) and the Overall response rates (CR+CRu+PR) will also be described |
| Time to Next Anti-Lymphoma Treatment (TTNLT) | 5.5 years | time from randomization to the date of first documented administration of any new anti-lymphoma treatment (chemotherapy, radiotherapy, radio-immunotherapy, 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. |
| Molecular Response | M3 and M12 | Bcl-2-IgH rearrangement |
Other
| Measure | Time frame | Description |
|---|---|---|
| Secondary cancers | 5.5 years | classification by type of cancer |
| Number of SAE from the first administration | 1 year | for Rituximab SC as of C1 cohort |
| Causes of death | 5.5 years | classification by cause of death |
| Pharmacokinetic parameters of rituximab will be used to estimate individual area under the concentration curves of rituximab (AUC). | 5.5 years | The AUC will be used to describe the relationship between rituximab pharmacokinetics and clinical response (objective response, survival). |
