What is the optimal choice of therapy for a patient with Hodgkin variant of Richter's transformation from underlying CLL/SLL?

I treat it similar to denovo Hodgkins Lymphoma with Brentuximab AVD for high risk versus ABVD for standard risk. If EBER-positive lymphoma, then there is a role for rituximab use in addition to chemo. Gupta et al., PMID 35291669
