BOTHELL, Wash. and VANCOUVER, British Columbia, Sept. 6, 2011 /PRNewswire/ -- OncoGenex Pharmaceuticals, Inc. (NASDAQ: OGXI) announced today that data from two studies, a Phase II clinical study and a pre-clinical study, evaluating the investigational compound custirsen (OGX-011/TV-1011), were published in the September issues of the journals Clinical Cancer Research and Cancer Research.
Custirsen inhibits the production of clusterin, a protein commonly over-produced in cancer cells and a cause of treatment resistance. Two Phase III studies evaluating custirsen in men with castrate-resistant prostate cancer (CRPC) are ongoing: the SYNERGY clinical trial - designed to evaluate an overall survival benefit for custirsen in combination with first-line docetaxel treatment, and the Prostate Cancer SATURN Trial - which will evaluate a durable pain palliation benefit in patients receiving second-line chemotherapy. Both studies are currently enrolling CRPC patients.
Phase II Data Published in Clinical Cancer Research
Data from a Phase II clinical study of custirsen in combination with docetaxel retreatment or mitoxantrone as second-line chemotherapy in patients with metastatic castrate-resistant prostate cancer (mCRPC) was published in the September 1, 2011 issue of Clinical Cancer Research.
In the clinical study, custirsen combined with docetaxel retreatment resulted in overall survival of 15.8 months. When custirsen was combined with mitoxantrone, overall survival was 11.5 months. The Phase II study also evaluated pain responses in patients with mCRPC. Overall, the pain response was durable (greater than or equal to three months) in 88 percent of patients who had pain or were on opioids for pain at study entry.
"These are encouraging results because we observed durable pain responses in many patients who had di
