Two Onapristone Phase I Clinical Study Abstracts Selected for Poster Presentations

FLEMINGTON, N.J., May 5, 2014 (GLOBE NEWSWIRE) -- Arno Therapeutics, Inc. (OTCQB:ARNI), a clinical stage biopharmaceutical company focused on the development of oncology therapeutics, today announced that abstracts outlining two, separate ongoing Phase I clinical trials evaluating its investigational lead compound onapristone have been accepted for poster presentation at the upcoming 50thAmerican Society of Clinical Oncology (ASCO) Annual Meeting, being held May 30 - June 3, 2014 in Chicago, Illinois.

Arno will present the objectives, methods and study designs for its two ongoing studies evaluating targeted therapy onapristone, including the Phase I trial in women with progesterone receptor expressing tumors and the Phase I/II trial in men with advanced castration-resistant prostate cancer (CRPC), who have failed treatment with abiraterone or enzalutamide.

The list of abstracts and timing of the presentations is provided below.

  • A randomized, parallel-dose phase 1 study of onapristone (ONA) in patients (pts) with progesterone receptor (PR)-expressing cancer

    Abstract: #TPS2643

    Poster: #98B

    First / Presenting Author: Paul H. Cottu, MD, MSc; Institut Curie, France

    General Poster Session: Developmental Therapeutics - Clinical Pharmacology and Experimental Therapeutics

    Date, Location: Sunday, June 1, 8:00 AM - 11:45 AM; S Hall A2

     
  • A phase 1-2 study of the type I progesterone receptor (PR) antagonist onapristone (ONA) in patients (pts) with advanced castration-resistant prostate cancer (CRPC)

    Abstract: #TPS5097

    Poster: #224B

    First / Presenting Author: Joaquin Mateo, MD; The Institute of Cancer Research & The Royal Marsden NHS Foundation Trust, United Kingdom

    General Poster Session: Genitourinary (Prostate) Cancer

    Date, Location: Monday, June 2, 1:15 PM - 5:00 PM; S Hall A2  

Glenn Mattes, President and Chief Executive Officer of Arno Therapeutics, said, "The abstracts accepted for poster presentation at this year's ASCO meeting are a testament to the strides we have made to advance our strategic clinical development plan for onapristone. We continue to actively enroll patients in two Phase I trials to evaluate this oral anti-progestin, which has the potential to be a first-in-class compound approved for oncology indications and provide chemotherapy-sparing treatment to cancer patients who express a specific biomarker. We are excited by the momentum generated thus far and look forward to discussing further at the Annual Meeting."

Onapristone is an oral anti-progestin 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 breast, endometrial and other tumors driven by aberrant function of the PR. 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 currently under development.
