RecruitingDrug trialThe Relapse from MRD Negativity As Indication for Treatment (REMNANT) StudyThe REMNANT study will evaluate whether treating minimal residual disease (MRD) relapse after first line treatment prolongs progression free survival and overall survival for myeloma patients versus treating relapse after first line treatment at progressive disease. To establish a homogenous group of MRD negative patients after first line treatment including autologous stem cell transplantation, patients are enrolled at diagnosis and treated with Norwegian standard of care first line treatment. MRD negative patients will move on to the randomized part.
