Positron Emission Tomography With Innovative Laboratory Techniques for Improved Risk and Disease Assessment in Newly Diagnosed Multiple Myeloma Patients

Sponsor: Universiteit Antwerpen

Summary

This study investigates newly diagnosed multiple myeloma patients following standard of care treatment. The primary endpoint of the study is to determine minimal residual disease (MRD) by combining 2 techniques in order to better predict progression free survival (PFS) of a patient. Secondary endpoint is to gain more insight into diagnostic features to better stratify patients based on risk factors for early relapse. Both endpoints could lead to a more patient specific treatment in the future. Participants will be followed throughout their standard of care treatment. This treatment consists of indcution chemotherapy, followed by autologous stem cell transplant (ASCT), followed by lenalidomide maintenance therapy. * Before start of induction chemotherapy the patient will receive a whole-body FDG PET/LDCT scan and an additional bone marrow aspirate sample will be taken during a routine bone marrow punction. This sample will be used for whole exome sequencing (WES). * For those patients who achieve at least a very good partial response (VGPR) after induction chemotherapy and ASCT a repeat whole body FDG PET/LDCT scan will be performed before start of maintenance therapy. This scan will be repeated for a third time after 1 year of maintenance therapy. Besides this, an additional bone marrow aspirate sample will be taken for MRD detection. This will be done before start of maintenance therapy, after 1 year of maintenance therapy and after 2 years of maintenance therapy. MRD detection is done by next generation flow cytometery (NGF). * During mantenance therapy patient follow-up will be performed at least every 3 months to determine best response to therapy or possible relapse (based on routine lab information). * Those patients who do not achieve VGPR or better will not need to receive a whole body FDG PET/CT scan and MRD detection by flow cytometry, but these patients will undergo the same follow-up during maintenance therapy. * In case of relapse, for all patients, an additional bone marrow aspirate sample will be taken for WES (during a routine bone marrow investigation).
