Exhibit 99.1

OncoGenex Pharmaceuticals, Inc. Provides Update on Clinical Development Program and

Reports Financial Results for Fourth Quarter and Year End 2012

Conference call to be held on Thursday, March 7, 2013 at 4:30 p.m. Eastern Time

BOTHELL, WA., and VANCOUVER, British Columbia, March 7, 2013 – OncoGenex Pharmaceuticals, Inc. (NASDAQ: OGXI) today highlighted key clinical development activities for its two product candidates, custirsen and OGX-427 and announced its fourth quarter and year end 2012 financial results.

Custirsen Clinical Development Highlights

 

   

The Company announced completion of patient enrollment of more than 1000 men in the primary registration Phase 3 SYNERGY study in the fourth quarter of 2012. The SYNERGY study is designed to evaluate a survival benefit for custirsen, in combination with first-line docetaxel chemotherapy, in men with metastatic castrate-resistant prostate cancer (CRPC). The expected timing of results is based on a pre-specified number of death events that is projected to occur in the fourth quarter of 2013, with data results expected to be announced in the first-half of 2014.

 

   

Patient enrollment began in the third quarter of 2012 in the Phase 3 AFFINITY study, evaluating a survival benefit for custirsen in combination with Jevtana® (cabazitaxel) as second-line chemotherapy. AFFINITY aims to enroll approximately 630 men with CRPC and is being conducted at sites throughout North America, Europe and Australia.

 

   

Patient enrollment began in the third quarter of 2012 in the Phase 3 ENSPIRIT trial, a randomized Phase 3 study in approximately 1,100 patients with advanced or metastatic non-small cell lung cancer (NSCLC). ENSPIRIT will evaluate the potential survival benefit of combining custirsen with docetaxel as second-line chemotherapy. Custirsen has also recently received Fast Track designation from the FDA for the second-line treatment of advanced NSCLC when combined with docetaxel in patients with disease progression following treatment with a first-line, platinum-based chemotherapy doublet regimen.

OGX-427 Clinical Development Highlights

 

   

In December 2012, the Company announced the initiation of the Pacific trial, an investigator-sponsored, randomized phase 2 study evaluating OGX-427 in approximately 80 men with CRPC who are experiencing a rising prostate-specific antigen (PSA) while receiving Zytiga® (abiraterone acetate). The study is currently enrolling at sites in the United States and Canada.

 

   

The company-sponsored, randomized phase 2 clinical trial of OGX-427 in combination with gemcitabine and cisplatin in patients with metastatic bladder cancer, Borealis-1, continues to enroll patients throughout the United States, Canada and Europe. The study aims to enroll approximately 180 patients and is expected to complete patient accrual in the second half of 2013.


   

The Company also recently announced plans for the initiation of an investigator-sponsored, randomized Phase 2 study evaluating OGX-427 in patients with advanced or metastatic bladder cancer who have disease progression following initial platinum-based chemotherapy. The trial, Borealis-2, will seek to enroll approximately 200 patients to receive either OGX-427 plus docetaxel treatment or docetaxel treatment alone and is expected to begin in the first half of 2013.

 

   

Pacific, Borealis-1 and Borealis-2 are part of the “ORCA” (On-going studies evaluating treatment Resistance in CAncer) program that encompasses clinical studies of OGX-427 across multiple cancer indications. Plans to initiate additional studies as part of the ORCA program will be announced in the coming months.

Financial Update and Results

 

   

Revenue for the fourth quarter and year ended December 31, 2012 increased to $9.8 million and $20.1 million, respectively. This compares with $1.2 million and $5.5 million, respectively, in the same periods in 2011. The increase in 2012 compared to 2011 was due to an increase in revenue earned through the Company’s strategic collaboration with Teva, as a result of the clinical development activities associated with the AFFINITY trial which was initiated in August 2012. Revenue for 2012 included recognition of $18.3 million from the $30.0 million upfront payment, as well as $1.8 million earned through collaborative research.

 

   

At December 31, 2012, the $30.0 million advanced reimbursement received from Teva in December 2009 was fully expended resulting in a Current Deferred Collaboration Revenue balance of zero. Teva is required to fund all additional expenses under the Amended Clinical Development Plan.

 

   

Total operating expenses for the fourth quarter and year ended December 31, 2012 increased to $16.0 million and $46.0 million, respectively, compared with $9.2 million and $27.8 million, respectively, in the same periods in 2011. The increase in 2012 as compared to 2011 was due primarily to higher clinical study expenses associated with the start-up of the AFFINITY trial, increased patient enrollment in the Borealis-1 trial, OGX-427 manufacturing costs and increased employee expenses, including stock-based compensation expense. These increases were partially offset by lower preclinical expenses. Included in operating expenses for the fourth quarter and year ended December 31, 2012 was a $1.7 million restructuring gain related to revised assumptions used to estimate the value of the Company’s excess lease liability.


   

Net loss for the fourth quarter and year ended December 31, 2012 was $4.1 million, or $0.28 per diluted common share, and $21.1 million, or $1.56 per diluted common share, respectively. Net loss for the fourth quarter and year ended December 31, 2011 was $9.6 million, or $0.98 per diluted common share, and $14.7 million, or $1.51 per diluted common share, respectively. The net loss in the years ended December 31, 2012 and 2011 included a non-cash gain on revaluation of our warrant liability of $4.5 million and $7.4 million, respectively.

 

   

We had $75.4 million in cash, cash equivalents and short-term investments as of December 31, 2012, compared to $64.9 million as of December 31, 2011.

 

   

2013 cash guidance:

 

   

Net cash requirements are expected to be in the range of $40 million to $50 million.

 

   

Year-end cash, cash equivalents and investments are expected to be in the range of $25 million to $35 million.

 

   

Based on our current expectations, we believe our capital resources as of December 31, 2012 will be sufficient to fund our currently planned operations into 2015.

 

   

At March 7, 2013, we had 14,658,766 shares outstanding.
