HOVON 135 - New treatment for elderly leukemia patients

Together with the Haemato Oncology Foundation for Adults in the Netherlands (HOVON), we are conducting the trial HOVON 135 with the aim to improve the treatment for patients who are older than 65 years and who are suffering from leukemia (AML – acute myeloid leukemia) or high-risk myelodysplastic syndrome (MDS), and to better understand the mechanism of these diseases. MDS is a preleukemic disease and very often transforms into a AML that roots in genetically modified stem cells in the bone marrow. Such stem cells are no longer able to produce fully functional blood cells. Patients participating in this trial also suffer from co-existing diseases or have a high risk to become affected by such diseases.

This trial is highly important because elderly patients are the largest patient population that suffers from AML and MDS. However, this patient population is generally underrepresented in clinical trials. In general, an intense chemotherapy is unsuitable for AML and MDS patients who are older than 65 years. Therefore, they get treated with decitabine that acts on the level of the DNA. With our trial, we investigate the effect of the combination of decitabine and ibrutinib on cancer therapy, in different hospitals. Ibrutinib is an active substance that inhibits the protein Bruton-Tyrosinkinase (BTK). This protein supports the growth and survival of cancer cells. We would like to find out how tolerable, safe and effective the combination of these two drugs is as a treatment for elderly patients suffering from AML or MDS.
