EHA 2025 | The disease-modifying potential of CALR-targeted therapies in MPNs

JAK inhibitors are a mainstay in the treatment of myeloproliferative neoplasms (MPNs), helping to reduce spleen volume and improve symptoms. However, these agents do not address the underlying cause of the disease. In this video, Jean-Jacques Kiladjian, MD, PhD, Saint-Louis Hospital & Paris Diderot University, Paris, France, briefly comments on the disease-modifying potential of mutant calreticulin (CALR)-targeted therapies, which is a hot topic in the field of MPNs. This interview took place at the 30th Congress of the European Hematology Association (EHA) in Milan, Italy.

Transcript

We have big expectations with these new strategies targeting the clone itself with specific drugs and not only JAK inhibition. That has very important issues that are mostly to address not only the mutant clones but also sometimes inflammation, for example for some of the JAK inhibitors and other targets. But here we are just targeting the malignant cell itself, the source of the cell and hopefully the leukemia-initiating cells...

We have big expectations with these new strategies targeting the clone itself with specific drugs and not only JAK inhibition. That has very important issues that are mostly to address not only the mutant clones but also sometimes inflammation, for example for some of the JAK inhibitors and other targets. But here we are just targeting the malignant cell itself, the source of the cell and hopefully the leukemia-initiating cells. So we hope that with this type of drugs we may eliminate the mutant clone, the malignant clone and hopefully maybe achieve a cure for some of these patients. That is not the case currently with JAK inhibitors.
