Trial in Progress: A Randomized, Double-Blind, Placebo-Controlled, Multicenter Phase 2 Study of AK117/Placebo in Combination with Azacitidine in Patients with Newly Diagnosed Higher-Risk Myelodysplastic Syndromes (AK117-205) () - Dec 7, 2024 - Abstract #ASH2024ASH_8743; P2 Stratification factors will be based on IPSS-R scores : ?4.5, >4.5-6, and >6.The primary endpoint is complete remission rate (CRR) assessed by investigators based on 2023 International Working Group (IWG 2023) response criteria (Zeidan A et al, Blood, 2023), and to determine the optimal dose of AK117 for future confirmatory trials (can expand this Phase 2 trial to a Phase 3 trial). Key secondary endpoints include overall response rate (ORR), duration of response (DoR), event-free survival (EFS), overall survival (OS), rate and duration of transfusion independence (TI), time to transformation to acute myeloid leukemia (AML), safety assessed by incidence and severity of adverse events (AEs), pharmacokinetics (PK) and immunogenicity.
- |||||||||| Reticulocyte Hemoglobin Content As a Diagnostic Tool for Myelodysplastic Syndrome: Findings from a 20-Year Retrospective Study () - Dec 7, 2024 - Abstract #ASH2024ASH_8737;
CHr is used in the evaluation of iron content to assess iron deficiency anemia; however, our findings suggest that elevated CHr (with its very high specificity) could be a valuable diagnostic tool for MDS, particularly in patients with complicating health conditions.Conclusion : These preliminary results indicate that the Reticulocyte Hemoglobin content has moderate sensitivity and very high specificity for diagnosing Myelodysplastic Syndrome (MDS) in the veteran population at our hospital. Further analysis and a larger sample size may help refine these findings and improve the diagnostic accuracy.

FOLR2 up-regulated IRF2 and IRF2BP2 expression levels and inhibited normal erythropoiesis.Taken together, our findings demonstrated that SHMT2-folate-folate receptor axis inhibited erythropoiesis in MDS, and targeting SHMT2 had therapeutic effectiveness for MDS treatment. Our findings also provided more comprehensive understanding on the relationship between folate and erythropoiesis.
- |||||||||| The Relationship between Anemia, Transfusion Dependence, Quality of Life and Survival in Myelofibrosis () - Dec 7, 2024 - Abstract #ASH2024ASH_8714;
Among them, one identified a significant correlation between anemia and increased symptom scores; another observed a numerical but not statistically significant difference in symptom reduction or HRQoL improvement between anemic and non-anemic groups; and the third study noted a greater improvement for those who responded to anemia treatment compared to non-responders.Only 1 study reported on TD and HRQoL and found a significant association between requiring transfusions and greater symptom burden.Conclusion : Evidence collated in this study demonstrates that anemia and TD have a detrimental association with survival in MF across variations in patient characteristics and clinical settings and should be considered as part of treatment decision-making. Limited available evidence indicates a trend between anemia, TD and poorer HRQoL and increased symptom burden in MF, however additional research is required to confirm and quantify this relationship.
- |||||||||| Outcome of Splenectomy in JAK2 Inhibitor Treated Patients with Myelofibrosis: A Mayo Clinic Experience in 34 Consecutive Cases () - Dec 7, 2024 - Abstract #ASH2024ASH_8699;
In addition, among 5 non-transplanted patients with baseline thrombocytopenia ( 100 x 109/L (median; 170 x 109/L, range : 119-279 x 109/L) within 3 months post-procedure.Conclusions : Splenectomy following JAKi-resistant or intolerant MF is associated with improvement of transfusion-dependent anemia (46% response), resolution of severe thrombocytopenia (80%), and may allow for successful transition to ASCT (35%). However, the procedure is associated with significant perioperative complications occurring in the majority of patients and underscores the need for future collaborative studies to develop selection criteria and evaluate alternative treatment modalities.

Cost Comparison of Ruxolitinib and Momelotinib in Patients with Myelofibrosis and Anemia () - Dec 7, 2024 - Abstract #ASH2024ASH_8694; One limitation of this model is the lack of precise estimates of transfusion costs; however, analyses with alternate estimates for transfusion costs varied the magnitude but consistently resulted in cost savings with ruxolitinib. In addition, due to the lack of accurate data in total cost of care, this model did not incorporate other clinical benefits associated with either ruxolitinib or momelotinib, including symptom response rate, spleen response rate, and potential secondary benefits of lower transfusion need, which are also important considerations in addition to cost.Conclusions : The model predicts substantial per-patient cost savings with ruxolitinib due to its lower pharmacy costs, which offset estimated higher transfusion costs, and suggests the clinical transfusion benefit of momelotinib does not lead to savings in the cost of care.
