DUBLIN, Calif., June 20, 2013 (GLOBE NEWSWIRE) -- Astex Pharmaceuticals, Inc. (Nasdaq:ASTX), a pharmaceutical company dedicated to the discovery and development of novel small molecule therapeutics, today announced that updated clinical data from the dose escalation part of a randomized phase 1/2 clinical trial of subcutaneous SGI-110, a novel hypomethylating agent, in patients with relapsed/refractory acute myelogenous leukemia (r/r AML) will be presented in an oral session during the European Cancer Congress 2013 (ECCO-ESMO-ESTRO) in Amsterdam, Netherlands September 27 - October 1, 2013.
Abstract #3.601, "Study of the correlation of baseline biomarkers and DNA demethylation to clinical responses in a phase 1/2, randomized study of SGI-110, a novel subcutaneous (SC) hypomethylating agent (HMA), in the treatment of relapsed/refractory (r/r) acute myeloid leukemia (AML)," has been selected for oral presentation in the "Hematological Malignancies" proffered paper session on September 28
th at 11:15 am CEST.
The presentation will include details of r/r AML responses in the dose escalation part of the trial, and the correlation between these responses and several baseline and DNA methylation biomarkers.
SGI-110 is a novel small molecule, DNA-hypomethylating agent administered as a single small volume subcutaneous injection. SGI-110 demonstrated activity in restoring silenced tumor suppressor gene expression in cancer cells by reversal of DNA methylation and inducing responses in previously treated MDS and AML patients. SGI-110 is wholly owned by Astex Pharmaceuticals.
About the SGI-110 study in MDS and AML patients (Study SGI-110-01):
The SGI-110-01 trial is a randomized phase 1/2 study in patients with MDS and AML. The trial completed its phase 1 dose escalation segment (Part A) and the results were presented at the December 2012 ASH meeting, "Results From the Dose Escalation Phase of a Randomized Phase 1-2 First-in-Human (FIH) Study of SGI-110, a Novel Low Volume Stable Subcutaneous (SQ) Second Generation Hypomethylating Agent (HMA) in Patients with Relapsed/Refractory MDS and AML." A copy of this presentation is available on the Astex Pharmaceuticals website,
www.astx.com , in the pipeline, presentations and publications section.
This study is currently in the phase 2 dose expansion segment (Part B) of the study. Its primary objective is to estimate overall response rates in four patient cohorts (relapsed/refractory AML; relapsed-refractory MDS; front-line elderly AML not suitable for induction chemotherapy; and front-line MDS). Secondary objectives include estimating the incidence and severity of adverse events, duration of response, overall survival, and the correlation of demethylation, genetic, and pharmacologic biomarkers with response.
