Management of Relapsed/Refractory Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma in the Era of Targeted Therapies.

Clinical trials have established the role of Bruton tyrosine kinase inhibitors, selective BCL-2 inhibition, and anti-CD20 monoclonal antibodies as treatment options for CLL/SLL. The role of chimeric antigen receptor T cells has shown promise in individuals with CLL/SLL in early phase clinical trials. Novel therapeutic approaches with targeted therapies have redefined the management of CLL/SLL in both the front-line and relapsed/refractory settings. Optimal management in terms of sequencing or combining therapies, especially in individuals with high-risk features, remains a challenge. The emerging role of cellular therapies has the potential to build upon and further improve the current treatment paradigm.
