Summary:

      This is a two-cohort, multicenter, open-label study of tafasitamab (MOR208) combined with
      idelalisib or venetoclax in adult patients with R/R CLL or R/R SLL pretreated with a BTK
      inhibitor (e.g., ibrutinib) as single agent or as part of combination therapy. Patients
      completing the study treatment are invited to participate in an optional biomarker sub-study.

                  such therapy

               -  single-agent or combination therapy with a BTKi for at least one month must be
