ProNAi Reports 2015 Year-End Financial and Operational Results

VANCOUVER, March 3, 2016 /CNW/- ProNAi Therapeutics, Inc. (NASDAQ: DNAI), a clinical-stage oncology company advancing novel therapeutics for patients with cancer and hematological diseases, today reported its financial and operational results for the year ended December 31, 2015.

"During 2015, we continued to transform ProNAi into a world-class oncology drug development company, securing both the talent and capital required to pursue our vision of developing and commercializing a pipeline of promising clinical-stage oncology assets with the potential to provide meaningful therapeutic outcomes to patients with cancer," said Dr. Nick Glover, President and CEO of ProNAi Therapeutics. "Concurrent with building our company, we continued to advance our lead asset PNT2258, operationalizing two Phase 2 trials in 2015, Wolverine and Brighton, that are at the forefront of a concerted registration-oriented clinical development program planned for the drug. In addition to PNT2258, during 2015 we began evaluating novel product candidates available for licensing or acquisition, with the goal of maximizing our clinical development capabilities and leveraging the full potential of our team by advancing a broad and diversified pipeline of assets."

"We anticipate reporting initial interim data from the Wolverine trial in third-line DLBCL in the second quarter of 2016. This trial has been designed to identify and characterize patient populations who respond to PNT2258 on the basis of their genetics and disease characteristics and will be essential to determining potential paths to registration for the drug," added Dr. Glover. "We recently started enrolling the Brighton trial in Richter's transformation and expect to report interim data from this trial before the end of 2016. We are also designing a number of additional Phase 2 trials that could support the registration and commercialization strategies for PNT2258. Two planned trials, Cypress and Granite, will evaluate PNT2258 in combination with standard-of-care treatment regimens for the treatment of second-line DLBCL in the "transplant eligible" and "transplant ineligible" patient populations respectively. We are also designing trials evaluating PNT2258's potential in DLBCL in combination with a targeted anti-cancer drug, and in other hematological malignancies as well. Although we maintain a strong balance sheet, we are carefully considering the timing of these additional trials with a view to maximizing PNT2258's potential while deploying our capital prudently."

2015 Operational Highlights:

• Operationalized the Wolverine Phase 2 trial evaluating single-agent PNT2258 in third-line relapsed or refractory DLBCL, opening more than 20 clinical sites during 2015 that are now actively recruiting patients.
• Initiated the Brighton Phase 2 trial evaluating single-agent PNT2258 in Richter's transformed CLL.
• Completed a successful IPO in July 2015, raising more than $158 million in gross proceeds. ProNAi shares began trading on the NASDAQ Global Market on July 16, 2015 under the symbol "DNAI."
• Strengthened the ProNAi management team, appointing six additional experienced senior executives including Dr. Barbara Klencke, M.D., as Chief Development Officer. Dr. Klencke is an accomplished oncology drug developer with a demonstrable track record of success, having made substantial contributions to the development and approval of several important oncology products including Kyprolis, Kadcyla, Avastin and Tarceva.
• Expanded the company from approximately 25 employees to more than 50 employees and opened our corporate headquarters in Vancouver, Canada.
• ProNAi (NASDAQ:DNAI) was selected for addition to the NASDAQ Biotechnology Index (NASDAQ:NBI)

2015 Financial Results (all amounts reported in U.S. currency)
Total operating expenses for the year ended December 31, 2015 were $35.8 million compared to $22.6 million for the year ended December 31, 2014. Total operating expenses include non-cash stock based compensation of $3.2 million and $0.3 million for the years ended December 31, 2015 and 2014, respectively.

Research and development expenses increased to $26.4 million for the year ended December 31, 2015 from $19.1 million for the year ended December 31, 2014. These increases were primarily due to expenses related to the continuation of our PNT2258 clinical trials, the manufacture of PNT2258 and an increase in personnel-related costs.  Expenses for the year ended December 31, 2014 include a one-time $11.0 million milestone payment that was made to Novosom AG during the second quarter of 2014.

General and administrative expenses increased to $9.5 million for the year ended December 31, 2015 from $3.5 million for the year ended December 31, 2014. These increases were primarily due to increased personnel-related costs and professional fees incurred in support of activities as a public company and corporate growth.

For the year ended December 31, 2015, ProNAi incurred a net loss of $53.3 million compared to a net loss of $23.9 million for the year ended December 31, 2014.  The net loss includes a non-cash charge related to the change in fair value of preferred stock warrants of $17.4 million and $1.4 million for the years ended December 31, 2015 and 2014, respectively.

At December 31, 2015, ProNAi had $150.2 million in cash and cash equivalents compared to $39.2 million in cash, cash equivalents and short-term investments at December 31, 2014.
