OncoGenex Pharmaceuticals, Inc. Provides Clinical Development Update and Reports Financial Results for Third Quarter 2012

BOTHELL, Wash. and VANCOUVER, British Columbia, Nov. 8, 2012 /PRNewswire/ -- OncoGenex Pharmaceuticals, Inc. (NASDAQ: OGXI) today announced third quarter 2012 financial results and highlighted key clinical development activities of its two product candidates, custirsen and OGX-427.

Custirsen Clinical Development Highlights

• The Company announced completion of patient enrollment in the primary registration Phase 3 SYNERGY study. The SYNERGY study is designed to evaluate a survival benefit for custirsen, when added to first-line chemotherapy, in men with metastatic castrate-resistant prostate cancer (mCRPC). Over 1000 men have now been enrolled.  The survival primary endpoint data are event-driven and results are expected by the end of 2013.
• The Phase 3 AFFINITY study, evaluating a survival benefit for custirsen in combination with Jevtana® (cabazitaxel) as second-line chemotherapy in approximately 630 men with CRPC, was initiated in the third quarter. This global study will be conducted at sites throughout North America, Europe and Australia.
• The ENSPIRIT trial, an international, randomized Phase 3 study in approximately 1,100 patients with advanced or metastatic non-small cell lung cancer (NSCLC), was initiated in the third quarter. The trial will evaluate the potential survival benefit of combining custirsen with docetaxel as a second-line chemotherapy in patients who have progressed after initial chemotherapy treatment has failed.

OGX-427 Clinical Development Highlights

• Preliminary data from an investigator-sponsored Phase 2 clinical trial of OGX-427 in chemotherapy-naive patients with metastatic CRPC were presented at the European Society for Medical Oncology Annual Meeting (ESMO) in September 2012. The updated study results showed a higher number of patients without disease progression at 12 weeks and greater declines in prostate-specific antigen (PSA) and circulating tumor cells (CTC) with OGX-427 plus prednisone treatment compared to prednisone alone. The study continues to demonstrate an acceptable safety profile of OGX-427 and final study results are expected in 2013.
• The randomized, Phase 2 clinical trial of OGX-427 in patients with metastatic bladder cancer continues patient accrual, with sites throughout North America and Europe. The trial aims to enroll approximately 180 patients and will evaluate the overall survival benefit of OGX-427 in combination with gemcitabine and cisplatin.
• An investigator-sponsored, randomized Phase 2 study evaluating OGX-427 in combination with Zytiga® (abiraterone acetate) in patients with CRPC is expected to begin enrollment in late 2012 or early 2013.

Third Quarter 2012 Financial Update and Results

• Revenue for the third quarter and nine months ended September 30, 2012 increased to $6.6 million and $10.3 million, respectively, compared with $1.2 million and $4.3 million, respectively, in the same periods in 2011. The increase in 2012 as compared to 2011 was due to higher revenue earned through our strategic collaboration with Teva, resulting from clinical development activities associated with the AFFINITY trial.
• As of September 30, 2012, $9.1 million of the $30 million advanced reimbursement received from Teva in December 2009 was included on our Balance Sheet as Current Deferred Collaboration Revenue. This advance reimbursement balance will continue to be reduced as we incur direct and indirect custirsen development costs. As a consequence of initiating the AFFINITY trial, we continue to 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 third quarter and nine months ended September 30, 2012 increased to $14.9 million and $30.1 million, respectively, compared with $5.3 million and $18.6 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 startup of the AFFINITY trial, patient enrollment in our clinical trial evaluating OGX-427 in patients with metastatic bladder cancer and associated manufacturing costs and higher employee expenses, including stock based compensation expenses.  These increases were partially offset by lower preclinical expenses.
• Net loss for the third quarter and nine months ended September 30, 2012 was $5.9 million, or $0.40 per diluted common share, and $17.0 million, or $1.29 per diluted common share, respectively. This is compared with net income of $4.5 million, or $0.45 per diluted common share in the three months ended September 30, 2011 and a net loss of $5.1 million, or $0.52 per diluted common share for the nine months ended September 30, 2011.  The net loss in the three and nine months ended September 30, 2012 included a non-cash gain on revaluation of our warrant liability of $2.3 million and $2.5 million, respectively.  The net income in the three months ended September 30, 2011 included an $8.6 million non-cash gain on revaluation of our warrant liability and the net loss in the nine months ended September 30, 2011 included a $9.0 million non-cash gain on revaluation of our warrant liability.
• We had $85.1 million in cash, cash equivalents and short-term investments as of September 30, 2012, compared to $64.9 million as of December 31, 2011.
• 2012 cash guidance:
  • Annual net cash requirements are expected to be in the range of $45 million to $50 million.
  • Year-end cash, cash equivalents, investments and receivables from Teva are expected to be in the range of $68 million to $73 million and include the receipt of proceeds from our March offering of common stock.
• Based on our current expectations, we believe our capital resources as of September 30, 2012 will be sufficient to fund our currently planned operations into 2015.
• At November 7, 2012, we had 14,656,916 shares outstanding.
