The goal of this research study is to identify an antigen-specific antibody profiling biomarker associated with increased risk of any infections in patients with Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma (CLL/SLL) or Multiple Myeloma (MM).~Research procedures including screening for eligibility, clinic visits, and blood tests.~This involves performing blood tests which detect antibodies directed against specific pathogens and measure their functional capacity, and collecting information about outcomes in patients.~Participation in this research study is expected to last 2 years.~It is expected that about 150 people CLL or MM will take part in this research study, and this will predominantly include people with CLL/SLL.~Takeda is supporting this research study by providing funding.
The aim of this research study is to use advanced immunology laboratory analysis to identify a more precise blood test that will predict infection risk in patients with Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma (CLL/SLL) or Multiple Myeloma (MM).
