FLEMINGTON, N.J., April 13, 2015 (GLOBE NEWSWIRE) -- Arno Therapeutics, Inc. (OTCQB:ARNI), a clinical stage biopharmaceutical company primarily focused on the development of therapeutics for cancer and other life threatening diseases, today announced the upcoming presentation of three posters supporting the ongoing clinical development program for lead compound onapristone at the American Association for Cancer Research (AACR) Annual Meeting 2015 , being held April 18-22 in Philadelphia, PA.
Details for the three poster presentations are as follows:
Tuesday, April 21; 1:00-5:00 p.m. ET
Poster Session: PO.ET05.01. Pharmacokinetics and Pharmacodynamics
- Abstract #4512 (Poster #10) – Onapristone in patients (pts) with progesterone receptor (PR)-expressing cancers: PK results from part 1 of a randomized, parallel-dose phase 1 study
- Abstract #4523 (Poster #21) – Population pharmacokinetic (PPK) modeling of onapristone in patients (pts) with progesterone receptor (PR)-expressing cancers
Tuesday, April 21; 8:00 a.m. - 12:00 p.m. ET
Poster Session: PO.EN02.01. Hormonal Regulation of Tumor Growth and Metastasis
- Abstract #3471 (Poster #24) – Comparative assessment of in vitro activity and activated progesterone receptor (APR) biomarker predictivity for multiple antiprogestins
Arno is currently enrolling patients in a Phase II clinical trial of onapristone in patients with metastatic or recurrent endometrioid tumors that express the activated progesterone receptor (APR), and in a separate Phase I/II clinical trial of onapristone in patients with castration resistant prostate cancer whose tumors are progesterone receptor (PR) positive.
Onapristone is an oral, anti-progestin hormone blocker that has been shown in previous Phase II clinical trials (not sponsored by Arno) to exhibit anti-tumor activity in patients with breast cancer. In pre-clinical testing, onapristone has been shown to block the activation of PR, which is believed to be a mechanism that inhibits the growth of APR driven breast, endometrial and other, primarily gynecological tumors. APR has the potential to function as a biomarker of anti-progestin activity, as detected by a companion diagnostic currently under development with Arno's partner, Leica Biosystems.
