What this Trial Is About

This phase Ib trial tests the safety and effectiveness of tafasitamab, acalabrutinib, and obinutuzumab in treating patients with previously untreated chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL). CLL and SLL are types of cancer that develops from a specific white blood cell called B cells or B lymphocytes. Tafasitamab and obinutuzumab are monoclonal antibodies that may interfere with the ability of cancer cells to grow and spread. Acalabrutinib is in a class of medications called kinase inhibitors. It blocks a protein called BTK, which is present on B-cell cancers such as CLL at abnormal levels. This may help keep cancer cells from growing and spreading. Giving tafasitamab, acalabrutinib, and obinutuzumab may kill more cancer cells in patients with previously untreated CLL and SLL.
