Aaron T. Gerds, MD, of Cleveland Clinic Taussig Cancer Institute, talks about treating the anemia many patients with myelofibrosis experience because of JAK inhibitor therapy.

Amer Methqal Zeidan, MBBS, MHS, of Yale University and Yale Cancer Center, discusses phase III findings on the first-in-class telomerase inhibitor imetelstat, which was given to patients with heavily transfusion-dependent non-del(5q) lower-risk myelodysplastic syndromes that are resistant to erythropoiesis-stimulating agents. Imetelstat resulted in a significant and sustained red blood cell (RBC) transfusion independence in 40% of these heavily transfused patients. The response was also durable and accompanied by an impressive median hemoglobin rise of 3.6 g/dL, and seen in patients with and without ring sideroblasts. Importantly, reduced variant allele frequency was observed in the most commonly mutated myeloid genes which correlated with duration of transfusion independence and hemoglobin rise, therefore suggesting a disease-modifying potential of this agent (Abstract 7004).
Guillermo Garcia-Manero, MD, of The University of Texas MD Anderson Cancer Center, discusses phase III findings from the COMMANDS trial. Compared with epoetin alfa, luspatercept improved red blood cell transfusion independence and erythroid response, as well as the duration of response in erythropoiesis-stimulating agent–naive, transfusion-dependent patients with lower‐risk myelodysplastic syndromes (Abstract 7003).
Patients with lower-risk myelodysplastic syndromes (MDS) who received luspatercept to treat anemia instead of erythropoiesis-stimulating agents (ESAs)—the current standard of care—needed fewer blood transfusions and clinic visits. These findings from the phase III COMMANDS trial were presented by...

They also identified the gene region that is demethylated and responsible...
Mutations in SF3B1 and U2AF1 can drive overexpression of activated IRAK4—which regulates inflammation and promotes cancer cell growth and survival—and are associated with a poor prognosis for patients with high-risk myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). Emavusertib is a...
Ruben A. Mesa, MD, of Mays Cancer Center at UT Health San Antonio MD Anderson Cancer Center, discusses new findings from the MOMENTUM study.

Alba Rodriguez-Meira, DPhil, of the University of Oxford, discusses a comprehensive analysis of the genetic, cellular, and molecular landscape of TP53-mediated transformation, providing insights into the evolution of chronic hematologic malignancies toward an aggressive acute leukemia. Because TP53 is the most commonly mutated gene in human cancer, these findings may well be of broad relevance (Abstract 3).
