Teva and OncoGenex Announce Updates to Custirsen Development Program in Advanced Prostate Cancer

Second Phase 3 Trial Evaluating Survival Benefit of Custirsen Planned to Initiate in 2012

JERUSALEM & BOTHELL, Wash. & VANCOUVER, British Columbia--(BUSINESS WIRE)--Mar. 8, 2012-- Teva Pharmaceutical Industries Ltd. (NASDAQ:TEVA) and OncoGenex Pharmaceuticals, Inc. (NASDAQ: OGXI) announced today an update on their development program for custirsen, a product candidate being evaluated in Phase 3 studies for castrate-resistant prostate cancer (CRPC).

In a revised agreement between the two companies, the clinical trial program will now include the initiation of a Phase 3 study to evaluate if custirsen has the potential to improve survival rates for prostate cancer patients when combined with the recently-approved, second-line chemotherapy drug Jevtana® (cabazitaxel).

The new trial, which aims to enroll approximately 630 men and is expected to begin later this year, will be conducted in lieu of the Prostate Cancer Saturn Study, a trial designed with a primary endpoint of measuring a durable pain palliation benefit for custirsen in second-line treatment of CRPC. The shift in focus to evaluate overall survival in second-line prostate cancer is a result of numerous, recently-approved agents that are redefining the standard of care in this patient setting.

"The amendments made to the Phase 3 program reflect the rapidly-evolving CRPC landscape and our commitment to ensure custirsen data are aligned with requirements to demonstrate improvements in survival across the treatment continuum," said Lesley Russell, Senior Vice President, Head of R&D for Global Branded Products at Teva Pharmaceuticals. "Developing custirsen for patients suffering from advanced prostate cancer remains a top priority within the Teva Oncology product-line and we believe this new trial is a reflection of that commitment."

Custirsen's other Phase 3 study, SYNERGY, evaluating a survival benefit in the first-line CRPC setting, continues to accrue patients and is expected to complete enrollment later this year. The companies are increasing the enrollment from 800 to 1000 patients to optimize the potential to be submitted to regulatory agencies independent of additional Phase 3 studies. The increase in enrollment is not expected to alter timelines for completion of the study.

Additional details on the updates to the custirsen development program will be discussed during the OncoGenex Quarterly Earnings Call to be held this afternoon, March 8, at 4:30pm EST. To join the call, dial (877) 606-1416 (U.S. & Canada) or (707) 287-9313 (International).

About Custirsen

Custirsen is the only compound currently in development designed to inhibit the production of clusterin, a protein commonly over-produced in cancer cells, and one cause of treatment resistance. In Phase 2 trials of patients with metastatic CRPC, custirsen combined with docetaxel showed a 6.9 month improvement in overall survival over docetaxel alone. Additionally, 50 percent of patients experienced durable pain palliation for a duration of 12 weeks or longer. Custirsen has received Fast Track designation from the U.S. Food and Drug Administration (FDA).
