Official title
A Phase II Study of Ofatumumab-Based Induction Chemoimmunotheraphy Followed by Consolidation Ofatumumab Immunotherapy in Previously Untreated Patients With Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: \- Ofatumumab was approved by the U.S. Food and Drug Administration to treat patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) who have not responded to standard chemotherapy. Ofatumumab is a substance that recognizes specific types of white blood cells called B-lymphocytes, which become cancerous in CLL/SLL. Ofatumumab attaches to a molecule called CD20, which is found on the surface of B-cells, and destroys them. Previous studies have shown that ofatumumab can decrease the number of B-cells in patients with CLL/SLL who have been treated with chemotherapy, but more research is needed to determine it if can also be used to treat patients with previously untreated CLL/SLL. Objectives: \- To determine a safe and effective dose of ofatumumab, along with chemotherapy, to treat chronic lymphocytic leukemia or small lymphocytic lymphoma. Eligibility: \- Individuals at least 18 years of age who have been diagnosed with CLL or SLL that has not been treated with chemotherapy. Design: * Eligible participants will be screened with a physical exam, blood samples, lymph node and bone marrow biopsies, and imaging studies. * Participants will be separated into 2 groups: all participants will receive ofatumumab and fludarabine, and some participants will be selected to also receive cyclophosphamide (based on results of certain blood tests). * Participants will receive the study drugs (ofatumumab and fludarabine, and optional cyclophosphamide) by infusion for a maximum of 6 days, followed by 21 days off drug. * Participants will have 6 cycles of treatment according to a schedule set by the study doctors, and may have their dose levels adjusted if side effects develop. * Participants who have disease remaining after 6 cycles will receive additional ofatumumab every 2 months, starting 2 months after the end of the 6th cycle and continuing for a total of 4 doses, before entering the follow-up phase of the trial. Participants who do not have residual disease after 6 cycles will not receive additional therapy, and will immediately enter the follow-up phase of the trial. * Participants will have a follow-up exam every 2 to 4 months for 2 years after the end of treatment, and then as required by the study doctors for as long as the study remains open. These visits will involve a full medical exam, blood samples, lymph node and bone marrow biopsies, and imaging studies.
