Arno Therapeutics to Collaborate With Veridex on Development of Diagnostic
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.
