Geron Corporation has announced that five presentations highlighting the clinical activity of RYTELO® (imetelstat) in myeloid hematologic malignancies have been accepted for the 67th American Society of Hematology $(ASH)$ 2025 Annual Meeting, scheduled for December 6-9, 2025, in Orlando, FL. The accepted abstracts include one oral and four poster presentations, featuring new clinical and translational analyses of imetelstat in lower-risk myelodysplastic syndromes/neoplasms (LR-MDS) and myelofibrosis (MF). Among the presentations, an oral session will discuss the correlation between treatment-emergent cytopenias and clinical response with imetelstat in patients with LR-MDS, based on data from the IMerge Trial. Additionally, interim results from an investigator-led study of imetelstat in high-risk MDS will be presented as a poster, indicating limited single-agent activity in this patient group. These results are scheduled to be presented at the ASH 2025 meeting and have not yet been presented.
