Design outcomes

Primary

MeasureTime frame
Secondary Objective: 1. To correlate any differences in immune response to prognostic factors in CLL (Immunoglobulin VH gene mutation status, CD38, ZAP_70, del 11q and del 17p) and to novel immune regulatory factors.;Main Objective: 1. To determine the antibody response rates to subcutaneous vaccination with influenza vaccine (current world health organization recommended trivalent influenza vaccine for Northern hemisphere) in patients with untreated stage A chronic lymphocytic leukaemia (CLL). 2. To determine whether subsequent application of Imiquimod cream to the vaccination site will enhance the antibody and T-cell responses to influenza vaccination in a cohort of CLL patients. 3. To determine the antibody response rates to subcutaneous vaccination with influenza vaccine in a control group of age and sex matched subjects.;Primary end point(s): 1.To determine the antibody response rates to subcutaneous vaccination with influenza vaccine in patients with untreated stage A chronic lymphocytic leukaemia compared to age matched healthy controls. 2. To determine whether subsequent application of Imiquimod cream to the vaccination site will enhance the antibody and T-cell response.
