OncoGenex Pharmaceuticals, Inc. Reports Financial Results for Fourth Quarter and Year End

2011 and Provides Update on Clinical Development Program

Conference call to be held on Thursday, March 8, 2012 at 4:30 p.m. Eastern Time

BOTHELL, WA., and VANCOUVER, British Columbia, March 8, 2012 – OncoGenex Pharmaceuticals, Inc. (NASDAQ: OGXI) today announced its fourth quarter and year end 2011 financial results and provided an update on the clinical development programs for its product candidates, custirsen and OGX-427.

“We have had an exciting start to 2012, as our development programs for our two lead assets continue to gain momentum, specifically in advanced prostate cancer, ” said Scott Cormack, President and CEO of OncoGenex Pharmaceuticals. “The abiraterone data announcement today is excellent news for patients and for our company, as the development plans for both of our agents are now well aligned to a more defined landscape and are therefore positioned to improve upon existing treatments across the treatment continuum.”

Custirsen Clinical Development Updates:

 

   

Along with development partner, Teva Pharmaceutical Industries Ltd., OncoGenex announced plans to initiate a new Phase 3 study to evaluate the ability of custirsen to improve survival for patients with prostate cancer when combined with recently approved, second-line chemotherapy, Jevtana® (cabazitaxel). The new study will be conducted in lieu of the Prostate Cancer Saturn Study, which aimed to assess durable pain palliation as a primary endpoint. The study is expected to begin in the second-half of 2012.

 

   

The SYNERGY Phase 3 study, evaluating a survival benefit in first-line chemotherapy castrate-resistant prostate cancer (CRPC), continues to accrue patients and is expected to complete enrollment later this year. The companies updated the enrollment target for SYNERGY from 800 patients to 1000 patients which is expected to enhance the potential for SYNERGY to be reviewed by regulatory agencies independent of additional Phase 3 studies. Importantly, even with the trial size increasing by 25%, OncoGenex and Teva plan to complete enrollment later this year as originally disclosed.

 

   

OncoGenex continues to work with Teva to finalize clinical development plans for custirsen in non-small cell lung cancer and expects to initiate this program in the second-half of 2012.

OGX-427 Clinical Development Updates:

 

   

Preliminary data on OGX-427 for the treatment of prostate and bladder cancer were presented earlier this month at the ASCO 2012 Genitourinary Cancers Symposium.

 

   

A Phase 1 trial evaluating OGX-427 in patients with superficial or muscle-invasive bladder cancer demonstrated a trend towards decreased levels of Hsp27 and increased tumor cell death rates after intravesical treatment with OGX-427. Of the 15 patients treated with OGX-427, 33% had pathological complete responses in post-surgical tissue following 4 doses of OGX-427 administered intravesically over an 8 day period. A randomized Phase 2 clinical trial of OGX-427 in combination with gemcitabine/cisplatin in patients with metastatic bladder cancer is currently enrolling patients.

 

   

In chemotherapy-naive patients with metastatic CRPC, preliminary randomized Phase 2 study results showed that patients in the OGX-427 treatment arm had a higher number of patients without disease progression at 12 weeks, and greater declines in prostate-specific antigen (PSA)


 

and circulating tumor cells (CTC) compared to the control arm. OncoGenex announced plans to initiate a randomized Phase 2 clinical trial evaluating OGX-427 in combination with Zytiga® (abiraterone) in patients with CRPC, supported in part by investigator grant funding.

Financial Results

 

   

Revenue for the fourth quarter and year ended December 31, 2011 decreased to $1.2 million and $5.5 million, respectively, compared with $2.3 million and $13.6 million in the fourth quarter and year ended December 31, 2010. The decrease in 2011 as compared to 2010 was due to lower reimbursement revenue earned through our strategic collaboration with Teva resulting from manufacturing costs now being paid directly by Teva and lower clinical trial costs associated with the SATURN trial.

 

   

At December 31, 2011, $18.3 million of the $30 million advanced reimbursement received from Teva in December 2009 was included in our Balance Sheet as Current Deferred Collaboration Revenue. This advanced reimbursement balance will continue to be reduced as we incur direct and indirect custirsen development costs. As a consequence of initiating the new CRPC survival trial later this year, we currently expect that all remaining Current Deferred Collaboration Revenue will be recognized as Collaboration Revenue by the fourth quarter of 2012. Once the remaining amount of the advanced reimbursement from Teva has been drawn to zero, all of our costs associated with the clinical programs under our collaboration will be reimbursed by Teva quarterly.

 

   

Total operating expenses for the fourth quarter and year ended December 31, 2011 were $9.2 million and $27.8 million, respectively, compared with $4.2 million and $28.4 million in the fourth quarter and year ended 2010. The decrease in operating expenses in 2011 as compared with 2010 was due to a $4.0 million non-cash restructuring expense recorded in 2010 which resulted from the revision of our sublease income assumptions used to estimate the excess lease facility liability associated with our office space located in Bothell, Washington, offset by higher OGX-427 manufacturing and clinical trial costs, and higher employee expenses.

 

   

Net loss for the fourth quarter and year ended December 31, 2011 increased to $9.6 million, or $0.98 per diluted common share, and $14.7 million, or $1.51 per diluted common share, respectively, compared to net loss in the fourth quarter of 2010 of $2.8 million, or $0.31 per diluted common share, and a net loss of $12.6 million, or $1.79 per diluted common share, in the year ended 2010. The increase in net loss was primarily due to lower revenue recognized in 2011 in connection with the Collaboration Agreement with Teva, and higher expenses associated with our OGX-427 clinical trials.

 

   

We had $64.9 million in cash, cash equivalents and short-term investments as of December 31, 2011, compared to $85.1 million as of December 31, 2010.


2012 Outlook and Financial Guidance

 

   

We expect 2012 operating cash requirements of between $40 million and $45 million, and expect to end 2012 with cash, cash equivalents, investments, and receivables from Teva of between $20 million and $25 million. This increase from the $20.2 million in cash used in 2011 reflects the higher anticipated cash burn associated with the new Phase 3 study to evaluate an overall survival benefit for custirsen when combined with Jevtana®.

 

   

Based on our current forecast, and excluding any proceeds from potential new partnerships or financings we expect that our existing capital resources, including cash, cash equivalents, short term investments and amounts receivable, will support our operations into 2014. As at March 8, 2012, we had 9,750,119 shares outstanding.
