A Phase I/II, a Single Arm, Open-label Study of Ofatumumab (GSK1841157) in Patients With Previously Treated Chronic Lymphocytic Leukemia
In Brief
A Phase 2 clinical trial evaluating ofatumumab 100 mg, 1000 mg / vial for Leukaemia, Lymphocytic, Chronic. Completed, enrolled 10 participants across 7 sites in 2 countries.
Detailed Summary
Ofatumumab is an IgG1κ fully human monoclonal antibody (mAb) that specifically recognizes an epitope on the human differentiation antigen CD20 molecule. In vitro and in vivo studies demonstrated that ofatumumab depletes CD20 positive (CD20+) B cells through complement-dependent cytotoxicity (CDC) and antibody-dependent cell-mediated cytotoxicity (ADCC), which results in the antitumour effect. This is an open-label study to evaluate safety, tolerability, efficacy and PK profile of ofatumumab monotherapy in chronic lymphocytic leukemia (CLL) patients. Ofatumumab will be administered intravenously at the first dose of 300mg followed by 7 weekly infusions of 2000mg, followed by 4 infusions of 2000mg at every 4 weeks. Primary objective of the study (Part A) is to evaluate tolerability, and the study (Part B) is to assess overall response rate in CLL population. 10 subjects will be enrolled into this study. Subjects will be followed for 48 weeks.
