VANCOUVER, Aug. 12, 2016 /PRNewswire/ - ProNAi Therapeutics, Inc. (NASDAQ: DNAI), a drug development company focused on advancing targeted therapeutics for the treatment of patients with cancer, today reported its financial and operational results for the second quarter of 2016.

"During the second quarter, we successfully licensed our first new asset, PNT141, a potent, selective and orally bioavailable small molecule inhibitor of the Cdc7 kinase," said Dr. Nick Glover, President and CEO of ProNAi Therapeutics. "Our goal is to build a broad pipeline consisting primarily of assets that leverage discoveries on the leading edge of cancer biology. PNT141 highlights this strategy as Cdc7 has a central function in both DNA replication and DNA damage response, two mechanisms that are increasingly recognized as having critical roles in driving cancer. In addition to toxicology and manufacturing work, we are conducting a robust preclinical assessment of PNT141 aimed at further informing our clinical development plans and patient selection strategies as we prepare this product candidate for clinical trials."

In June 2016, the company reported that it had suspended development of the cancer drug PNT2258. This decision was informed by a review of the interim data from the Wolverine Phase 2 trial of PNT2258. Although modest efficacy was observed from PNT2258 in this interim analysis, the company did not view these data as robust enough to justify continued development of the drug. The company continues to review these data in order to determine next steps with the asset and technology; however, no further investment in PNT2258 or the underlying DNAi platform by ProNAi is contemplated and the company subsequently has closed its research facility based in Plymouth, Michigan, which supported these programs.

Second Quarter 2016 Financial Results (all amounts reported in U.S. currency)

Total operating expenses for the three months ended June 30, 2016 were $12.9 million compared to $6.6 million for the three months ended June 30, 2015.

Research and development expenses increased to $9.1 million for the three months ended June 30, 2016 from $4.7 million for the three months ended June 30, 2015. Research and development expenses increased to $15.8 million for the six months ended June 30, 2016 from $10.0 million for the six months ended June 30, 2015. These increases were primarily due to a non-recurring $2.8 million restructuring charge related to estimated close-out expenses for PNT2258, a $0.9 million upfront payment for the exclusive license of PNT141 and an increase in personnel-related costs. These increased costs were partially offset by a decrease in third-party manufacturing costs.

General and administrative expenses increased to $3.8 million for the three months ended June 30, 2016 from $1.9 million for the three months ended June 30, 2015. General and administrative expenses increased to $7.8 million for the six months ended June 30, 2016 from $3.3 million for the six months ended June 30, 2015. These increases were primarily due to a $0.3 million non-recurring restructuring charge, increased personnel-related costs and fees incurred in support of activities as a public company and corporate growth and costs pertaining to business development activities.

For the three months ended June 30, 2016, ProNAi incurred a net loss of $12.9 million compared to a net loss of $15.2 million for the three months ended June 30, 2015.  For the six months ended June 30, 2016, ProNAi incurred a net loss of $23.4 million compared to a net loss of $23.3 million for the six months ended June 30, 2015.  During the three and six months ended June 30, 2015, net loss included a non-cash charge related to the change in fair value of preferred stock warrants of $8.6 million and $10.0 million.
