Brief 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.

- indication for treatment as defined by the IWCLL guidelines
- Patients must have both of the following:
- relapsed or refractory disease while receiving a BTKi therapy or intolerance of such therapy
- single-agent or combination therapy with a BTKi for at least one month must be the patient's most recent prior anticancer therapy
- ECOG performance status of 0 to 2

- Laboratory Values
- Patients must meet adequate bone marrow function and adequate hepatic and renal function
- Females of childbearing potential must use a highly effective method of contraception
You may not qualify if:
- Diagnosis
- Patients who have:
- non-Hodgkin's lymphomas other than CLL/SLL
- transformed CLL/SLL or Richter's syndrome
- active and uncontrolled autoimmune cytopenia
- Previous and Current Treatment
- Patients who have received treatment with a BTK inhibitor within 5 days prior to Day 1 dosing
- Patients who have, within 14 days prior to D1 dosing:
- not discontinued CD20-targeted therapy, chemotherapy, radiotherapy, investigational anticancer therapy or other lymphoma specific therapy
- systemic corticosteroids in doses greater than prednisone equivalent to 20 mg/day with the exception of patients with signs of rapidly progressing disease
- received live vaccines with the exception of vaccination against influenza with inactivated virus or for pneumococcal diseases
