Arno Therapeutics to Collaborate With Veridex on Development of Diagnostic Test FLEMINGTON, N.J., June 3, 2013 (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 agreement with Veridex, LLC, a Johnson & Johnson company, to develop a diagnostic test to detect the presence of activated progesterone receptors (APRs) as a potential biomarker of anti-progestin activity in circulating tumor cells (CTCs). The diagnostic will help identify patients whom could potentially benefit from treatment with anti-progestins including onapristone, an orally-administered, investigational type 1 progestin receptor antagonist being developed by Arno. CTCs are cancer cells that have detached from a solid tumor in the body and are found in the bloodstream.The collaboration will allow Arno to utilize Veridex's proprietary technology, CELLSEARCH®, which uses an advanced cell separation technique called microfluidic separation integrated with innovative magnetic sorting, to isolate CTCs and further analyze the cells for the presence of APR.The CELLSEARCH® CTC System is the first and only standardized, FDA-cleared, semi-automated system that captures, isolates, and counts CTCs with a high level of sensitivity and specificity. In pre-clinical studies, the presence of APR has shown to be predictive of onapristone activity.Onapristone is believed to work by binding to progesterone receptor proteins, thereby inhibiting dimerization, phosphorylation and DNA transcription activity. Progesterone receptors (PRs) are found in particular cells including those of the female reproductive tissue and some cancers.^i The hormone progesterone binds to the receptors and may cause the cells to grow.^i Preclinical studies have shown that PRs can play a role as drivers of malignant cell growth in certain cancers. "We are pleased to work with Veridex as we believe its pioneering technology for isolating circulating tumor cells will serve as an important tool for the continued development and study of onapristone," said Glenn Mattes, chief executive officer and president, Arno Therapeutics."By taking blood samples from patients rather than obtaining tissue samples, we hope to create a simplified and less invasive process for identifying patients that are most likely to benefit from treatment with onapristone." The diagnostic test will be used in future clinical studies of onapristone, which the company is planning to begin in the second half of 2013.
