AUSTIN, Texas--(BUSINESS WIRE)-- Mirna Therapeutics, Inc. (Nasdaq:MIRN), a clinical stage biopharmaceutical company developing a broad pipeline of microRNA-based oncology therapeutics, today reported financial results for the fourth quarter and full year ended December 31, 2015, and provided an update on the Company's recent progress.

"Mirna had a highly productive 2015 as we continued to advance the first microRNA therapeutic in clinical development in cancer," commented Paul Lammers, M.D., M.Sc., Mirna's President and CEO. "Our lead microRNA product candidate, MRX34, has demonstrated clinically significant responses in multiple cancers, and we are preparing to advance it into two Phase 2 studies late this year. We also continued to broaden our understanding of its unique mechanism capable of inhibiting multiple oncogenic and immune-mediated pathways known to drive tumor growth."

Dr. Lammers continued, "On the corporate front, we raised a total of over $100 million from an IPO and two private placements during the year and strengthened our management team, leaving us well-positioned to advance our clinical development strategy and fully leverage our microRNA technologies for the treatment of cancers."

About Mirna Therapeutics, Inc.

Mirna is a clinical-stage biopharmaceutical company developing a broad pipeline of microRNA-based oncology therapeutics and is the first to establish clinical proof-of-concept for a microRNA replacement therapy for cancer. Mirna's lead product candidate, MRX34, a mimic of naturally occurring microRNA-34 (miR-34), is currently being studied in a Phase 1 clinical trial in patients with primary liver cancer, advanced solid tumors and hematological malignancies. miR-34 is one of the most widely published microRNAs and is considered a key regulator of multiple oncogenes across key oncogenic pathways, with the capacity to regulate more than 30 different oncogenes and repress the immune checkpoint signaling molecule PD-L1. The potential capacity to simultaneously affect multiple pathways and processes that are critical to cancer cell viability may make mimics of tumor suppressor microRNAs potent anti-cancer agents and less susceptible to drug resistance. Mirna plans to develop MRX34 as a monotherapy and in combination with other therapeutic modalities, such as targeted therapies and immuno-oncology agents. The Company was founded in 2007 and is located in Austin, Texas.
