Better treatment for blood cancer: study starts in Dresden and Kiel
Better treatment for blood cancer: study starts in Dresden and KielAt the beginning of 2026, RELEVANT (ETAL-5), currently Germany’s largest study on allogeneic stem cell transplantation for patients suffering from Acute Myeloid Leukemia (AML) or Myelodysplastic Syndrome (MDS), was launched. For many of these diseases, stem cell transplantation is currently the only curative treatment option. The study, led by researchers from Dresden and Kiel, aims to improve treatment options and long-term survival for older patients or patients with preexisting comorbidities.
"For most patients, transplantation is the only chance for curing blood cancer, which is why it’s essential for us to identify the most suitable treatment method," explains Prof. Christoph Röllig, Head of the Department of Haematology and the Study Center at Dresden University Hospital.
The researchers are comparing two internationally recognized chemotherapy-based regimens: the combination with treosulfan developed in Germany and the combination with melphalan, which is widely used in many other parts of the world.
"So far, we lack data on whether the therapy with treosulfan or melphalan is better tolerated or even more effective. That’s why a direct comparison in a so-called prospective randomized study, an advance-planned study in which treatments are randomly assigned, is so important," explains UKSH expert Prof. Friedrich Stölzel, who is also a professor at the Faculty of Medicine at Kiel University (CAU).
The study specifically targets older individuals over 50 years of age as well as patients with pre-existing conditions, for whom stem cell transplantation is associated with an increased risk.
“With the results, our primary goal is to improve survival rates for particularly vulnerable patient groups and, in the long term, to enhance and advance the safety and efficacy of allogeneic stem cell transplantation," says Dr. Désirée Kunadt.
About the study:
RELEVANT (ETAL-5) is a randomized Phase 2 study (IIT) conducted in the context of allogeneic stem cell transplantation for adult patients with AML or MDS. A total of 220 patients across Germany are set to be included in the study, and recruitment has just started.
The study is supported by medac GmbH and TUD Dresden University of Technology.
