Brentuximab Vedotin plus Lenalidomide and Rituximab for the treatment of patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL)
Résumé de l'étude
The purpose of this study is to compare the (positive or negative) effects of Brentuximab vedotin in combination with Lenalidomide (L) and Rituximab (R), compared to placebo (P) in combination with Lenalidomide and Rituximab for the treatment of DLBCL. There are two treatment groups in this study: One group receives Lenalidomide and Rituximab with Brentuximab vedotin (BV/L-R) The other group receives Lenalidomide and Rituximab with placebo (P/R-L). A placebo contains no active ingredient. The first six patients in this study will receive Lenalidomide and Rituximab with Brentuximab vedotin (BV/L-R). After that, assignment to the two treatments will be done randomly, i.e., like a lottery. This is a blinded study, the assignment to the two groups will only be disclosed at the end of the study for study participants, the principal investigator, and the study team. All individuals with diffuse large B-cell lymphoma who have relapsed (relapsed) or have not improved (refractory) despite treatment can participate.

Intervention étudiée
This study consists of a so-called screening phase, a treatment phase, and a follow-up phase after treatment completion.
If the screening assessments show that you can participate in the study, you will be randomly assigned to one of the two following treatment groups:
1) BV/R-L or 2) P/R-L.
The assignment to the two treatments will be done randomly, i.e., like a lottery;
Each of the two treatment arms consists of a treatment cycle every 3 weeks until disease stabilization is achieved.
You will spend the first day of each cycle in the hospital, where the study drug and Rituximab will be administered through an arm vein;
Lenalidomide will be given orally and the remaining doses for this cycle will be handed out for home intake.
If no reaction is achieved during the first cycle, Rituximab will be administered subcutaneously starting from the second cycle.
At each study visit, approximately 45-60 ml (3 to 4 tablespoons) of blood will be drawn. On day 15 of the first cycle and thereafter every 6 weeks, a computed tomography (CT) and a PET scan will be performed.
Treatment will continue until disease stabilization without progression or toxicity is achieved.
About 30 days after the start of the last cycle, you will be asked to attend a post-treatment follow-up appointment. This appointment will include a physical examination, a blood test, imaging, and a pregnancy test if indicated. Thereafter, quarterly telephone interviews will be conducted in the first year and then semi-annually to assess your health status and disease progression.

Maladie en cours d'investigation
This study is being conducted to determine whether the addition of Brentuximab Vedotin helps two medications better treat patients with diffuse large B-cell lymphoma (DLBCL). The participants in this study have DLBCL that has returned despite treatment or has not improved.
(BASEC)
- Histologically confirmed B-cell non-Hodgkin lymphoma. - Men and women aged at least 18 years. - Patients who have not adequately responded to at least two prior systemic therapies or have experienced a relapse. (BASEC)
Critères d'exclusion
- History of another malignant disease within the last two years or residual signs of a prior malignant disease. - History of progressive multifocal leukoencephalopathy (PML). - Pregnant and/or breastfeeding women cannot participate in this study. (BASEC)

Critères d'inclusion/exclusion
Inclusion Criteria:
- Participants with relapsed or refractory diffuse and transformed large B-cell
lymphoma (R/R DLBCL). DLBCL and cell of origin (GCB versus non-GCB) will be
histologically determined by local pathology assessment for the purposes of study
eligibility and stratification.
- Participants must have R/R disease following 2 or more lines of prior systemic
therapy.

used must have been for DLBCL
- Participants must be HSCT or CAR-T ineligible according to the investigator and must
meet at least one of the following criteria:
1. One or more co-morbidities, including cardiac, pulmonary, renal or hepatic
dysfunction that in the opinion of the Investigator make the participant

2. Active disease following induction and salvage chemotherapy
