MPNs

After 4 years of follow-up, a majority of patients with polycythemia vera (PV) that responded to treatment with ruxolitinib (Jakafi) maintained their responses, results from a randomized trial showed.

Treatment with pegylated interferon alfa-2a led to objective responses in about two-thirds of patients with hydroxyurea (Hydrea)-resistant/intolerant polycythemia vera or high-risk essential thrombocytopenia, a phase II study of salvage therapy showed.

Srdan Verstovsek, MD, of MD Anderson Cancer Center, discusses a study of sotatercept (ACE-011) alone and in combination with ruxolitinib in patients with myeloproliferative neoplasm (MPN)-associated myelofibrosis and anemia.

A novel pegylated formulation of interferon alfa-2b achieved a significantly higher rate of complete hematologic response compared with hydroxyurea (Hydrea) in patients with polycythemia vera, according to 2-year findings from the follow-up phase III CONTI-PV randomized trial.

The investigational activin receptor IIA ligand trap sotatercept safely increases hemoglobin levels in patients with myeloproliferative neoplasm (MPN)-associated myelofibrosis, both when used alone and in combination with ruxolitinib (Jakafi).

The investigational Nutlin family antagonist idasanutlin demonstrated significant activity and was well tolerated after multiple cycles of exposure in patients with refractory polycythemia vera.<br /> &nbsp;

Ruben A. Mesa, MD, Director of the UT Health San Antonio Cancer Center, discusses &nbsp;4-year follow-up results from the phase III RESPONSE trial, which investigated ruxolitinib (Jafaki) with best available therapy for the treatment of polycythemia vera (PV) during the 2017 ASH Annual Meeting.

John Mascarenhas, MD, associate professor, Icahn School of Medicine at Mount Sinai, discusses the role of <em>JAK2</em> inhibition in patients with polycythemia vera (PV).

John O. Mascarenhas, MD, associate professor of medicine, Icahn School of Medicine at Mount Sinai Hospital, discusses the optimal use of ruxolitinib (Jakafi) and the improved understanding of JAK2 inhibition of polycythemia vera.

Ruben Mesa, MD, director, UT Health San Antonio Cancer Center, discusses NCCN guideline updates in polycythemia vera and essential thrombocythemia.

Srdan Verstovsek, MD, PhD, recently discussed treatment considerations and decisions in the cases of 2 patients with myeloproliferative neoplasms.&nbsp;Verstovsek,&nbsp;professor of medicine, Department of Leukemia, The University of Texas MD Anderson Cancer Center, discussed the case scenarios during a&nbsp;<em>Targeted Oncology</em>&nbsp;live case-based peer perspectives dinner.

Advancements made in the field of molecular genetics for patients with myeloproliferative neoplasms may be increasingly incorporated into treatment decisions, according to a presentation by Ann Mullally, MD, during the 2017 SOHO Annual Meeting.

The treatment of myelofibrosis has changed significantly in the past few years, largely due to the approval of ruxolitinib (Jakafi). Although it provides durable improvements, the JAK inhibitor may be even more effective in combination&mdash;as inhibition of JAK-STAT signaling has not shown to be curative.

High-Risk Primary Myelofibrosis

Hydroxyurea Resistant Polycythemia Vera

Underlying Treatment of Myeloproliferative Neoplasms

The NCCN published its first set of guidelines for myeloproliferative neoplasms in October 2016 and is already looking to update and expand these guidelines to match the need for direction in diagnosing and treating patients with MPNs.
