FLEMINGTON, N.J., March 4, 2014 (GLOBE NEWSWIRE) -- Arno Therapeutics, Inc. (OTCQB:ARNI), a clinical stage biopharmaceutical company focused on the development of oncology therapeutics, today announced that it has signed an exclusive, worldwide license agreement with the University of Minnesota for technology related to a gene expression signature derived from archived breast cancer tissue samples. This technique has the potential to identify progesterone-stimulated pathway activation and in turn, help identify patients who would most likely benefit from treatment with Arno's lead compound, onapristone, an anti-progestin therapeutic aimed at treatment of men's and women's cancers.
Glenn Mattes, Chief Executive Officer of Arno Therapeutics, remarked, "Our agreement with the University of Minnesota offers Arno a strategic partnership with a leading academic institution and innovator in research, education and patient care in the oncology space. This technology gives Arno an additional platform for identifying patients with cancer who would most likely benefit from our personalized therapy."
The principal objective of gene expression studies is to identify one or more gene signatures in breast and other tumor types, genes whose transcriptional levels are uniquely associated with a specific biological phenotype.i Ideally, this gene signature, which indicates the presence of aberrant progesterone receptor activity, can then be used to select a patient population with cancer that are more likely to benefit from anti-progestin therapy.
Onapristone is an oral, anti-progestin hormone blocker that has been shown in previous Phase II clinical trials to exhibit anti-tumor activity in patients with breast cancer. In pre-clinical testing, onapristone has been shown to block the activation of the progesterone receptor (PR), which is believed to be a mechanism that inhibits the growth of APR-driven breast, endometrial and other tumors. Tests for the activated form of the progesterone receptor (APR) have the potential to function as a biomarker of anti-progestin activity, as detected by a companion diagnostic under development. Onapristone is currently being evaluated in a phase I clinical trial in women who have progesterone receptor expressing tumors in France.
Under the agreement, negotiated through the University's Office for Technology Commercialization, with the University of Minnesota, Arno will further develop the PR gene signature as a potentially predictive companion diagnostic for anti-progestins, including onapristone. The agreement enables the potential of incorporating such a companion diagnostic test into ongoing and future clinical studies of onapristone.
Carol Lange, PhD, Professor of Medicine, University of Minnesota, commented, "As progesterone receptors are implicated in cancer progression, we are excited by the possible outcomes resulting from investigation of the PR gene signature in breast cancer tissue samples, as illustrated by the expression pattern. The study of this gene signature may enable better, more targeted selection of patient candidates who will benefit most from anti-progestin therapeutics such as onapristone. We believe that the advent of personalized medicine in oncology represents a meaningful advancement in the area of cancer therapeutics. Onapristone is specifically aimed at targeting the aberrant actions of progesterone receptors. The potential development of a companion diagnostic for Arno's lead compound from this technology represents a significant step forward in our ability to truly realize the potential of personalized medicine."
David M. Jackson, Vice President, Diagnostics of Arno Therapeutics, noted, "Onapristone, a member of the class of anti-progestins, has the distinct ability to block the activation of the progesterone receptor. We believe this license agreement will enable Arno's diagnostic strategy to identify and develop multiple analytical methods to identify those patients whose tumors are APR-positive and may therefore benefit from targeted onapristone therapy."
