Determinants of the Response to BTK Degraders (BTKd) in Chronic Lymphocytic Leukemia

The primary outcome is the in-depth characterization of tumor cells and their microenvironment in CLL patients candidates or exposed to BTKd. Analyses will be performed using cellular biology (e.g., flow cytometry), molecular biology (e.g., RNA sequencing), and bioinformatics (e.g., deconvolution). Functional studies include the development of preclinical ex vivo models (2D/3D culture) and gene editing of primary cells using CRISPR/Cas9 technology, based on the expertise of Team 11 at CRCI²NA. The study will include 60 patients over a 9-year enrollment period. Each participant will be followed for 5 years, resulting in a total study duration of 14 years.
