CAP-100 for Relapsed/Refractory Chronic Lymphocytic Leukemia

This study is testing a drug called CAP-100 for people with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) that has come back or hasn't responded to at least two previous treatments. CAP-100 is a human-made antibody that targets a specific protein called CCR7. Researchers want to see how safe CAP-100 is and if it causes any side effects, especially at different doses. They will also look for early signs that the drug is helping patients. You may be able to join if you are at least 18 years old, have CLL or SLL that has relapsed or is refractory, and meet other health criteria. The study plans to enroll 18 participants, but the current recruitment status is unclear.
