Current Primary Outcome Measures  ICMJE
 (submitted: May 15, 2019)
  • Fraction of patients (n=5) for whom a sdAb could be generated that binds to the idiotype of the paraprotein. [ Time Frame: Within 2 years after study completion ]
    Reporting of the relative amount of patients for whom such sdAb could be successfully obtained
  • Amount of paraprotein-targeting sdAbs generated per patient and amount of sdAb families identified. [ Time Frame: Within 2 years after study completion ]
    Absolute amount of unique sdAbs obtained per patient and its average over all patients with successful generation of sdAb
  • Affinities of generated paraprotein-targeting sdAbs using BIAcore technology and ELISA techniques. [ Time Frame: Within 2 years after study completion ]
    Reporting of affinity (Kd) of selected sdAb per patient measured using BIAcore and ELISA techniques

Current Secondary Outcome Measures  ICMJE
 (submitted: May 15, 2019)
binding capacity to patient-derived myeloma cells (if available) [ Time Frame: Within 10 years after study completion ]
Binding of paraprotein-targeting sdAb to membrane-expressed paraprotein of multiple myeloma cells, obtained as leftover material from routinely performed bone marrow sampling in the 10 years after inclusion of the study subject, measured by mean fluorescence intensity in flow cytometry and/or semiquantitative scoring after immunohistochemistry staining of samples

Descriptive Information
Brief Title  ICMJE sdAb-based TRNT of Multiple Myeloma: a Feasibility Study
Official Title  ICMJE sdAb-based Targeted Radionuclide Therapy of Multiple Myeloma: a Feasibility Study
Brief Summary This study aims to show that antiidiotypic sdAb are a new, sensitive, specific and non-invasive tool for imaging and therapeutic purposes and provides a rationale for their clinical evaluation as a personalized treatment option for MM patients expressing surface paraprotein.
