Mirna Therapeutics Reports Third Quarter 2016 Financial Results and MRX34 Clinical Program Updates

AUSTIN, Texas--(BUSINESS WIRE)-- Mirna Therapeutics, Inc. (Nasdaq: MIRN), a biopharmaceutical company focused on microRNA-based oncology therapeutics, today reported financial results for the third quarter of 2016 and provided an update on recent developments.

MRX34 CLINICAL PROGRAM

In September 2016, the Company voluntarily halted the ongoing Phase 1 trial of its first product candidate, MRX34, following multiple immune-related serious adverse events (SAEs) observed in patients dosed with MRX34 over the course of the trial. Three of these immune-related events resulted in the patient's death. Subsequently, the U.S. Food and Drug Administration (FDA) notified the Company that the Investigational New Drug (IND) Application for MRX34 has been placed on full clinical hold. Among other comments, the FDA requested a final clinical study report be submitted and noted that a risk-benefit summary with sufficient justification for the continued development of MRX34 would be necessary if the Company requested removal of the clinical hold.

"We were disappointed with the outcome of our Phase 1 study, however, our first priority in developing innovative therapeutics is the safety of patients," said President and CEO Paul Lammers, M.D., M.Sc. "Based on our assessment of both potential therapeutic benefit and risk, we have decided to discontinue development of MRX34 and suspend our pipeline R&D programs."

The Company has initiated a plan to reduce personnel and expenses in order to preserve capital and streamline operations, and it plans to focus on meeting regulatory requirements related to closure of the Phase 1 trial as well as other operating activities consistent with the decision to discontinue development of MRX34. The Company also expects to explore and evaluate strategic alternatives with the goal of enhancing stockholder value.

THIRD QUARTER 2016 FINANCIAL RESULTS

Cash Position and Guidance: Cash, cash equivalents, and marketable securities totaled $66.7 million as of September 30, 2016, compared to $89.7 million as of December 31, 2015. The Company has no debt.

Beginning in the first quarter of 2017, after giving effect to the personnel and expense reductions, the Company expects its quarterly cash burn rate will range from $2.1 million to $2.3 million. This 2017 quarterly guidance includes contractual commitments and obligations, but excludes any one-time charges related to a strategic transaction should one be concluded.

Research and development expenses: Research and development expenses were $3.4 million and $11.6 million for the three and nine months ended September 30, 2016, respectively, compared to $4.7 million and $12.6 million during the comparable periods in 2015. The decrease for the three and nine months ended September 30, 2016 compared to the same period in 2015 was primarily attributable to higher costs incurred in 2015 associated with our Phase 1 clinical trial for MRX34, specifically adding additional sites and upfront drug manufacturing costs. The decrease in 2016 was partially offset by an increase in employee compensation, benefits and stock compensation.

General and Administrative Expenses: General and administrative expenses were $2.0 million and $6.1 million for the three and nine months ended September 30, 2016, respectively, compared to $1.6 million and $3.6 million during the comparable periods in 2015. The increase in general and administrative expenses was primarily attributable to increased employee compensation expense due to a higher headcount and higher outside professional and consulting costs, the majority of which were costs to comply with public company operating and reporting requirements.

Net Loss: Net loss was approximately $5.4 million and $17.6 million for the three and nine months ended September 30, 2016, compared to a net loss of $6.2 million and $16.2 million for the comparable periods in 2015. The results included non-cash, stock-based related compensation charges of $513,000 and $1,202,000 for the three and nine months ended September 30, 2016, respectively, and $210,000 and $561,000 for the comparable periods in 2015.
