NCCN Guidelines for MPN Reflect New Drugs, Focus on Clinical Trials

Understanding of myeloproliferative neoplasms (MPNs), a group of blood cancers that occur when a person’s bone marrow makes too many blood cells, has increased since discovery of the JAK2 mutation in 2005.1 Still, the first set of National Comprehensive Cancer Network Clinical Practice Guidelines in Oncology (NCCN Guidelines) for MPNs, which include myelofibrosis (MF), polycythemia vera (PV), and essential thrombocythemia (ET), did not appear until 2017, and through 2022 there were few updates.

But since then, the NCCN Guidelines for MPNs have had multiple updates per year, with the latest in August 2024,a sign of increased activity in the field. In an interview with The American Journal of Managed Care® (AJMC®), Aaron Gerds, MD, MS, who chairs the panel handling the MPN updates, confirms that the more frequent updates reflect new approvals and more options for patients.

“We are regularly looking at the published literature and updates in the field in order to make sure that these guidelines are very nimble, and that they are adjusted to reflect current practice,” said Gerds, who is associate professor of medicine and deputy director for clinical research at the Cleveland Clinic Taussig Cancer Institute. Some guidelines might be updated every 5 to 10 years; but if there’s nothing new, “there’s not a lot of sense in updating things in a large way.”

Conversely, updates often occur when new therapies are approved or become available, Gerds said, as was the case in September 2023 when momelotinib (Ojjaara), the fourth Janus kinase (JAK) inhibitor, became available for the treatment of intermediate or high-risk MF, including primary MF or secondary MF, and post-PV, and post-ET in adults with anemia.3

The most recent update puts a major focus on clinical trials; in many circumstances, they are listed as the preferred option over FDA-approved therapies; in the AJMC interview, Gerds explains how a pair of phase 3 trials involving ruxolitinib combinations will produce results very soon.
