Myeloproliferative Neoplasms

The novel JAK and AVCR1 inhibitor jaktinib demonstrated promising therapeutic activity in patients with myelofibrosis who were intolerant to or progressed on ruxolitinib.

Rusfertide demonstrated freedom from phlebotomy, sustained hematocrit control, and 12-week treatment completion in 69.2% vs 18.5% of patients with phlebotomy-dependent polycythemia vera who received placebo, meeting the primary end point of the phase 2 REVIVE trial.

Ruxolitinib was found to improve spleen volume and tumor symptom score in patients with myelofibrosis, irrespective of their anemia and transfusion status, according to data from a post-hoc analysis of the phase 3 COMFORT-I and -II trials.

Haifa Kathrin Al-Ali, MD, discusses the safety and efficacy findings from the dose-escalation portion of the phase 1/2 CA011-023 trial of BMS-986158 in combination with ruxolitinib or fedratinib in patients with intermediate- or high-risk myelofibrosis.

Treatment with pelabresib monotherapy led to a 60% confirmed complete or partial hematologic response at any time without incurring grade 4 or 5 treatment-related adverse effects in patients with high-risk essential thrombocythemia refractory or intolerant to hydroxyurea.

Prithviraj Bose, MD, discusses key data on the ability of pacritinib to reduce splenomegaly and disease symptoms in patients with myelofibrosis across the cytopenic spectrum.

Guillermo Garcia-Manero, MD, discusses key efficacy and safety findings from the phase 3 COMMANDS trial (NCT03682536) of luspatercept-aamt (Reblozyl) vs epoetin alfa in patients with lower-risk myelodysplastic syndrome.

Amer Zeidan, MBBS, discusses topline efficacy findings from the IMerge trial of imetelstat in patients with transfusion-dependent lower-risk myelodysplastic syndrome.

Treatment with the first-in-class direct and competitive telomerase inhibitor imetelstat resulted in statistically significant and clinically meaningful efficacy in patients with heavily transfusion dependent, non-del(5q) lower-risk myelodysplastic syndrome that is relapsed or refractory to erythropoiesis stimulating agents, according to findings from the phase 3 IMerge trial.

Luspatercept-aamt led to a higher rate of sustained transfusion independence compared with erythropoiesis stimulating agents in patients with ESA-naïve, lower-risk myelodysplastic syndrome.

The National Comprehensive Cancer Network Clinical Practice Guidelines in Oncology have been revised to include ropeginterferon alfa-2b-njft as a preferred treatment option for patients with high- and low-risk polycythemia vera, irrespective of treatment history.

The FDA has approved avapritinib (Ayvakit) for the treatment of adults with indolent systemic mastocytosis.

Treatment with ruxolitinib generated superior responses vs treatment with best available therapy in patients with hydroxycarbamide-intolerant or -resistant polycythemia vera, according to findings from the phase 2 MAJIC-PV trial.

John Mascarenhas, MD, discusses ongoing trials and research in myelofibrosis.

John Mascarenhas, MD, discusses first-line treatment decisions for patients with myelofibrosis.

The first patients have been dosed in the phase 3b ECLIPSE PV trial, which is evaluating an accelerated dosing schedule of ropeginterferon alfa-2b-njft for the treatment of patients with polycythemia vera.

John Mascarenhas, MD, discusses the background of the phase 3 MANIFEST-2 trial investigating the combination of pelabresib and ruxolitinib vs ruxolitinib plus placebo in patients with myelofibrosis who have not been previously treated with a JAK inhibitor.

Tania Jain, MBBS, discusses notable differences in baseline characteristics and donor sequencing, according to a retrospective study of patient outcomes following blood or marrow transplant in 4 common donor types of myelofibrosis.

Enrollment to the phase 3 MANIFEST-2 trial, which is examining the safety and efficacy of pelabresib plus ruxolitinib vs ruxolitinib alone in patients with JAK inhibitor–naïve myelofibrosis, has completed and topline findings are anticipated by the end of 2023.

The phase 3 MATTERHORN trial examining roxadustat as an anemia treatment in patients with transfusion-dependent, lower-risk myelodysplastic syndrome did not meet its primary end point.

Sagar Patel, MD, discusses how the timing of autologous stem cell transplant can affect outcomes in those with myelofibrosis, including the risk of patients developing post-transplant complications.

Onco-nursing experts highlight the best practices and latest treatment regimens for patients presenting with the 3 most common myeloproliferative neoplasms: myelofibrosis, polycythemia vera, and essential thrombocythemia.

Shared closing thoughts on the future treatment landscape for myeloproliferative neoplasms, including future and emerging areas of research and remaining areas of unmet need.

A review of recent trial data evaluating combination therapy approaches with ruxolitinib in myelofibrosis, including the rationale and potential clinical benefits associated with the use of these emerging strategies.

The combination of selinexor at 60 mg and ruxolitinib induced rapid and durable spleen responses and improved symptoms at weeks 12 and 24 in patients with treatment-naïve myelofibrosis, according to updated data from the phase 1 XPORT-MF-034 trial.
