Arno Therapeutics, Inc. (OTCBB: ARNI) announced today that it has signed an exclusive, worldwide licensing agreement with privately held Invivis Pharmaceuticals to develop the investigational drug, onapristone, an anti-progestin hormone blocker that has been shown to have considerable anti-tumor activity in breast cancer.
“Almost half of all breast cancers are associated with a bio-marker which may predict for the activity of onapristone regardless of menopausal status,” said Glenn Mattes, president and chief executive officer of Arno Therapeutics. “Onapristone appears to have a unique ability to block the activated bio-marker and tumor growth, which makes it a promising potential treatment for breast, endometrial and other cancers. We have prepared a detailed development program for this compound and look forward to evaluating it in future clinical trials.”
Arno also plans to develop a companion diagnostic to identify patients who are positive for the bio-marker and may benefit from treatment with onapristone.
Dr. Erard M. Gilles, founder and chief executive officer of Invivis, stated: “Invivis and Arno share a deep commitment to oncology drug development and are enthusiastic about the therapeutic potential of onapristone. Together, we have the expertise and resources to advance this promising therapy.”
Pursuant to the terms of the license agreement, Arno will pay Invivis certain research, clinical and regulatory milestone payments as well as royalties on net sales of licensed products. In addition to the license agreement, Arno will receive certain clinical development support services from Invivis pursuant to a separate agreement.
