FOSTER CITY, Calif., Jun 14, 2021--(BUSINESS WIRE)--Geron Corporation (Nasdaq: GERN), a late-stage clinical biopharmaceutical company, today announced that two poster presentations of new clinical data and analyses related to imetelstat, the Company’s first-in-class telomerase inhibitor, are now available on Geron’s website as well as to participants of the EHA2021 Virtual Congress.
"These poster presentations further support imetelstat’s differentiated approach to potentially target the malignant stem and progenitor cells in the bone marrow by inhibiting telomerase activity," said Aleksandra Rizo, M.D., Ph.D., Geron’s Chief Medical Officer. "Through this novel mechanism of action, imetelstat has the potential to alter the course of MDS and MF which distinguishes it from other treatments currently approved or in development. We look forward to confirming these results in our ongoing Phase 3 clinical trials, IMerge Phase 3 in lower risk MDS and IMpactMF in refractory MF."
Title: Efficacy of Imetelstat is Independent of Molecular Subtypes in Heavily Transfused Non-Del(5q) Lower Risk MDS (LR-MDS) Relapsed/Refractory (R/R) to Erythropoiesis Stimulating Agents (ESA)
Poster Code: EP910
New data and analyses were presented on the clinical efficacy of imetelstat in molecularly defined subtypes based on cytogenetic and mutation profiles for patients in the IMerge Phase 2 clinical trial. As reported at previous EHA meetings, meaningful and durable transfusion independence were observed in patients from IMerge Phase 2, including transfusion-free periods greater than one year, as well as substantial increases in hemoglobin. The current presentation reported clinical responses across different cytogenetic and molecularly defined categories whereby responses were independent of mutation status or number of mutations. These data support the unique telomerase inhibition mechanism of action of imetelstat and the potential to target the malignant stem and progenitor cells of the underlying disease.
Title: Imetelstat Demonstrates an Acceptable Safety Profile in Myeloid Malignancies
Poster Code: EP1106
Safety data from the Phase 2 IMbark and IMerge trials were further analyzed to understand the characteristics of hematologic and non-hematologic adverse events. These analyses highlighted that the imetelstat-related cytopenias are short, reversable and with limited clinical consequence when managed with the dose modification guidelines in the protocols. These data are further evidence for the on-target effect of imetelstat based on the selective reduction of malignant cells in the bone marrow through telomerase inhibition resulting in the observed meaningful clinical benefits for patients in the Phase 2 trials.
Imetelstat is a novel, first-in-class telomerase inhibitor exclusively owned by Geron and being developed in hematologic myeloid malignancies. Data from Phase 2 clinical trials provide strong evidence that imetelstat targets telomerase to inhibit the uncontrolled proliferation of malignant stem and progenitor cells in hematologic myeloid malignancies resulting in malignant cell apoptosis and potential disease-modifying activity. Imetelstat has been granted Fast Track designation by the United States Food and Drug Administration for both the treatment of patients with non-del(5q) lower risk MDS who are refractory or resistant to an erythropoiesis-stimulating agent and for patients with Intermediate-2 or High-risk MF whose disease has relapsed after or is refractory to janus kinase (JAK) inhibitor treatment.
Geron is a late-stage clinical biopharmaceutical company focused on the development and potential commercialization of a first-in-class telomerase inhibitor, imetelstat, in hematologic myeloid malignancies. The Company currently is conducting two Phase 3 clinical trials: IMerge in lower risk myelodysplastic syndromes and IMpactMF in refractory myelofibrosis.

Investors are cautioned that such statements, include, without limitation, those regarding: (i) imetelstat’s potential to alter the course of MDS and MF; (ii) that imetelstat has potential disease-modifying activity; (iii) the potential of imetelstat to target the malignant stem and progenitor cells of the underlying disease; and (iv) other statements that are not historical facts, constitute forward-looking statements. These forward-looking statements involve risks and uncertainties that can cause actual results to differ materially from those in such forward-looking statements. These risks and uncertainties, include, without limitation, risks and uncertainties related to: (a) whether Geron overcomes all of the potential delays and other adverse impacts caused by the current or evolving effects of the COVID-19 pandemic, and overcomes all the enrollment, clinical, safety, efficacy, technical, scientific, intellectual property, manufacturing and regulatory challenges to complete its two Phase 3 clinical trials; (b) whether regulatory authorities permit the further development of imetelstat on a timely basis, or at all, without any clinical holds; (c) whether any future efficacy or safety results may cause the benefit-risk profile of imetelstat to become unacceptable; (d) whether imetelstat actually demonstrates disease-modifying activity in patients; and (e) whether imetelstat demonstrates that it targets the malignant stem and progenitor cells of the underlying disease in patients.
