E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine the efficacy of influenza vaccination in Monoclonal gammopathy of Undetermined Significance patients Is vaccination with trivalent inactivated influenza vaccine in MGUS patients useful?; Do these patients elicit adequate humoral and cellular T-cell responses after influenza vaccination? |
|
E.2.2 | Secondary objectives of the trial |
to find out what is the B-cell proliferation relation to clonal growth?; What happens to the plasma cell clones after vaccination? |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
MGUS Patients/controls - (MGUS patients only)patients have to fulfill the diagnostic criteria for MGUS - serum M protein<30g/L - Clonal plasma cells in bone marrow <10% - No myeloma related dysfunction - No other B-cell proliferative disease - informed consent
Multiple Myeloma inclusion criteria - patients who fulfill the diagnostic criteria for multiple myeloma - Monoclonal plasma cells in bone marrow >10% and/or presence of biopsy proven plasmacytoma - Monoclonal protein present in serum and/or urine - Myeloma related organ dysfunction o Calcium elevation in the blood S.

E.5 End points |
E.5.1 | Primary end point(s) |
Haemagglutinin Inhibition Test To detect the humoral immune response to influenza vaccination the haemagglutination inhibition (HAI) test will be performed at day 1, and 3-4 weeks following day 1. To evaluate the antibody responses, three parameters will be recorded: 1. Fourfold titre rises, including seroconversions (defined as a serological outcome where the initial sample tests negative (below detection level of the assay) compared to a true positive result in the second sample i.e. fourfold above the detection limit) 2. Achievement of titres 40, which are considered protective 3. Geometric mean titres (GMT)
Enzyme linked ImmunoSPOT (ELIspot) and memory B cell assay To enumerate the number of influenza specific plasma cells/ plasmablasts, an ELIspot assay will be performed on day 1, day 7 and 3-4 weeks following day 1. Memory b cells will be detected by culturing PBMCs for 6days with polyclonal mitogenic stimulants then quantifying by ELIspot.
Analysis of clonality RNA will be isolated and to quantify clonality, variable genes will be sequenced from RNA of ASCs
Cell-mediated responses Whole blood count, including lymphocyte subsets (CD3, CD4, CD8, CD19, CD16/56) will be measured from all participants. T cell subsets will also be further defined (central/ effector memory) by flow cytometry. To evaluate the cellular immune response to influenza vaccination, PBMC will be isolated from venous blood. T Helper cell populations in the PBMC samples will be analysed for their capacity to respond with proliferation and produce cytokines after in vitro stimulation with common mitogens and Influenza vaccine-derived antigens. Cell mediated responses to the 3 influenza variants will be assessed by IFN ELISPOT, Intracellular Cytokine (i.e. IFN, IL-2 and TNFα) detection by Flow Cytometry and assessment of proliferation of CD4 and CD8 T cells using CFSE dye dilution and analysis by Flow Cytometry.
