Study objectives:

  • Phase I, year 1-2

Primary objectives:

1. To determine the predictive value, sensitivity and specificity of patient-specific molecular MRD markers for resistant disease and relapse in patients with MDS undergoing SCT.

Secondary objectives:

  1. To define cut-off values signalling impending relapse for the different mutations (e.g. different cut-offs for TP53 and TET2).
  2. To evaluate the sensitivity of MRD from peripheral blood samples compared to bone marrow samples.
  3. To determine the prognostic value of pre-treatment mutational profile for outcome after SCT.
  4. To, during this clinical trial, collect a biobank of consecutive blood and bone marrow samples from each patient allowing for studies of stem / progenitor cells, microenvironment and immune system before and after transplantation with regard to genetic, epigenetic and immunological features.
  • Phase II, year 3-4

Primary objectives: 

  1. After having the digital PCR method established as an accredited method allowing for results of the MRD analyses to be delivered to treating clinicians, we aim to evaluate the efficacy of pre-emptive treatment on the MDS-clone and the potential of avoiding relapse. Most likely, approaches will differ between different MDS subsets / molecular profiles. We will take the results from the first phase into account before outlining the next phase in detail and will after send in a new ethical application. The transition from phase I to phase II will be evaluated by a safety committee headed by an independent researcher.
