Poster Session 6 Saturday, December 14; 7:30 - 9:00 a.m. CT Abstract #1282 Poster #P6-05-13FLEMINGTON, N.J., Dec. 14, 2013 (GLOBE NEWSWIRE) -- Arno Therapeutics, Inc. (OTCQB:ARNI), a clinical stage biopharmaceutical company focused on the development of oncology therapeutics, today announced that data from a biomarker study supporting its lead compound onapristone will be presented at a poster session at the 2013 CTRC-AACR San Antonio Breast Cancer Symposium (SABCS) annual meeting, being held December 10-14, 2013 in San Antonio, Texas. The symposium is hosted by the American Association for Cancer Research, The Cancer Therapy & Research Center at The University of Texas Health Sciences Center at San Antonio, and Baylor College of Medicine. Findings from the study "Tumor and Cellular Distribution of Activated Forms of ERα and PR in Breast Cancers" (Abstract #1282) will be presented during Poster Session 6 on Tumor Cell and Molecular Biology: Biomarkers on Saturday, December 14 from 7:30 – 9:00 a.m. CT in Exhibit Hall C of the Henry B. Gonzalez Convention Center. Data analysis from primary breast cancers further support the development of a diagnostic test to identify patient tumors with activated progesterone receptor (APR) and activated estrogen receptor (AER) as potential biomarkers of anti-progestin and anti-estrogen activity, respectively. Onapristone is an oral, anti-progestin hormone blocker that has been shown to have anti-tumor activity in breast cancer. Onapristone appears to have a unique ability to block the APR, which is believed to be a mechanism that may inhibit the growth of breast, endometrial and other tumors. APR has the potential to function as a biomarker of anti-progestin activity.
