Durable Continuous Transfusion Independence (TI) with Imetelstat in IMerge Phase 3 for Patients with Heavily Transfused Non-Del(5q) Lower-Risk Myelodysplastic Syndromes (LR-MDS) Relapsed/Ref... (SDCC - Halls G-H) - Nov 3, 2023 - Abstract #ASH2023ASH_6053; P2/3 In the IMerge phase 3 trial, imetelstat produced higher rates of TI for =8 weeks, =24 weeks, and =1 year (39.8%, 28.0%, and 17.8%) than placebo (15.0%, 3.3%, and 1.7%) in pts with non-del(5q) LR-MDS that was RBC-TD, R/R to/ineligible for ESAs, and na

Impact of Mutational Status on Clinical Response to Imetelstat in Patients with Lower-Risk Myelodysplastic Syndromes in the IMerge Phase 3 Study (SDCC - Halls G-H) - Nov 3, 2023 - Abstract #ASH2023ASH_6051; P2/3 While the sample size for specific mutations was small, consistent with the observation that patients with LR-MDS have a low number of specific mutations, TI responses in patients receiving imetelstat occurred regardless of the presence of mutations associated with poor prognosis or the number of mutations. Imetelstat showed comparable TI rates across different molecularly defined subgroups, suggesting that clinical benefit of imetelstat in patients with LR-MDS is independent of the underlying molecular pattern.

FORTITUDE: A Phase 2 Open-Label Study in Progress to Evaluate Etavopivat for the Treatment of Anemia in Patients with Lower-Risk Myelodysplastic Syndromes (SDCC - Halls G-H) - Nov 3, 2023 - Abstract #ASH2023ASH_4187; P2 Erythropoiesis-stimulating agents and other drugs, including lenalidomide, luspatercept and imetelstat (an investigational product), can lead to RBC transfusion independence and improve Hb levels in many patients; however, responses are generally transient and novel treatments are needed for this population...Additional exclusion criteria include prior treatment with azacitidine; decitabine; erythropoietin, other hematopoietic growth factor treatment or lenalidomide within 30 days of Day 1 or anticipated to be required during the study; and luspatercept within 30 days of Day 1 for NTD patients and within 16 weeks of Day 1 for TD patients...Summary : Etavopivat is a novel, investigational, once-daily, selective PKR activator with the potential to improve RBC health and lifespan. This phase 2 study will assess the safety of etavopivat and its impact on Hb levels and RBC transfusion burden in patients with LR-MDS and anemia.

Hematological Response to Frontline Treatment in Lower Risk Myelodysplastic Syndromes (LRMDS) Is Associated with Better Overall Survival (SDCC - Halls G-H) - Nov 3, 2023 - Abstract #ASH2023ASH_2293; In lieu of 2 recent randomized clinical trials demonstrating efficacy of luspatercept & imetelstat in LRMDS, we assessed the impact of response to sequential lines of treatment in LR-MDS on overall survival (OS) to guide our treatment choices and to determine whether erythroid stimulating agents (ESA) should still be our 1 st line of therapy...331 pts (55%) received SL which included HMA 43% (n= 142), lenalidomide 39% (n=130), luspatercept 7% (n=24), ATG 2% (n=8), investigational agent 4% (n=14), and other 4% (n=13)...Responses beyond SL were rarely observed. Identifying and moving agents with high HI rate as FL therapy and or selecting option based on predictors of best chance of response to a specific treatment as FL may lead to better overall survival.

Journal: Telomerase-Targeted Therapies in Myeloid Malignancies. (Pubmed Central) - May 22, 2023 We go on to discuss the development of telomere and telomerase targeted therapeutic candidates within the realm of myeloid malignancies. We overview all mechanisms of targeting telomerase that are currently in development with a particular focus on imetelstat, an oligonucleotide with direct telomerase inhibitory properties that has advanced the furthest in clinical development and has demonstrated promising data in multiple myeloid malignancies.

Journal: Novel Approaches and Future Directions in Myelodysplastic Syndrome Treatment. (Pubmed Central) - May 21, 2023 For higher-risk MDS patients, hypomethylating agent monotherapy continues to be the standard of care. However, with various novel hypomethylating agent-based combination therapies in advanced clinical testing and an increased emphasis on individualized biomarker-driven treatment decisions, the standard therapy paradigms might change in the future.

Why the last? This chapter was written years ago, before the IPSS-M, before the 5th edition WHO, before the ICC, before important new biological and genetic discoveries, before luspatercept and ASTX727 approval, and potentially imetelstat soon. So it’s already partly obsolete. (Twitter) - Mar 4, 2023
