Completed Upsized Initial Public Offering, Raising Gross Proceeds of $158.4 Million
Advanced Clinical Programs for PNT2258 in DLBCL and Richter's Transformed CLL
Strengthened Management Team and Board of Directors

VANCOUVER, Aug. 21, 2015 /CNW/ - ProNAi Therapeutics, Inc. (NASDAQ: DNAI), a clinical-stage oncology company pioneering a novel class of therapeutics based on its proprietary DNAi technology platform, today reported its financial and operational results for the second quarter of 2015.

"During the second quarter we continued to advance our clinical programs for PNT2258, opening clinical trial sites and enrolling patients into our Phase 2 Wolverine trial in DLBCL, while preparing for the initiation of our registration-oriented Phase 2 Brighton trial in Richter's Transformed CLL. We plan to initiate three additional Phase 2 trials in 2016 with PNT2258 to further investigate the potential breadth of opportunity of our first DNAi-based oncology drug candidate," said Dr. Nick Glover, President and CEO of ProNAi Therapeutics. "We also recently closed our IPO, which raised more than $158 million in gross proceeds to further support the development of PNT2258 and our DNAi platform."

Recent Highlights

• Appointed industry veterans Dr. Nicole Onetto, M.D., currently Deputy Director and Chief Scientific Officer at the Ontario Institute for Cancer Research, and Mr. Robert Pelzer, LLB., former President of Novartis Corporation, to ProNAi's Board of Directors.

Second Quarter 2015 Financial Results (all amounts reported in U.S. currency)

Total operating expenses for the three months ended June 30, 2015 were $6.6 million compared to $13.5 million for the three months ended June 30, 2014. Total operating expenses for the six months ended June 30, 2015 were $13.3 million compared to $15.8 million for the six months ended June 30, 2014.

For the three months ended June 30, 2015, ProNAi reported a net loss of approximately $15.2 million, compared to a net loss of $13.8 million for the quarter ended June 30, 2014. For the six months ended June 30, 2015, ProNAi incurred a net loss of $23.3 million compared to a net loss of $16.3 million for the six months ended June 30, 2014.

Research and development expenses decreased to $4.7 million for the three months ended June 30, 2015 from $12.7 million for the three months ended June 30, 2014. Research and development expenses decreased to $10.0 million for the six months ended June 30, 2015 from $14.5 million for the six months ended June 30, 2014. These decreases were primarily due to an $11.0 million milestone payment related to certain patented lipid nanoparticle delivery technology made to Novosom AG during the three months ended June 30, 2014. This decrease in expenses was partially offset by an increase in research and development expenses related to the continuation of our PNT2258 clinical trials, and an increase in headcount costs.

General and administrative expenses increased to $1.9 million for the three months ended June 30, 2015 from $0.8 million for the three months ended June 30, 2014. General and administrative expenses increased to $3.3 million for the six months ended June 30, 2015 from $1.3 million for the six months ended June 30, 2014. These increases were primarily due to increased headcount costs and professional fees incurred in connection with the preparatory work to become a public company.

As at June 30, 2015, ProNAi had $25.8 million in cash, cash equivalents and short-term investments compared to $39.2 million as at December 31, 2014. ProNAi received $143.6 million in net proceeds from its initial public offering in July 2015.

Subsequent to the closing of the IPO, there were approximately 30,058,105 shares of common stock issued and outstanding and 3,325,050 options issued and outstanding.
