Tekmira Provides Key Highlights of Analyst and Investor Day in New York

VANCOUVER, British Columbia, Nov. 21, 2014 (GLOBE NEWSWIRE) -- Tekmira Pharmaceuticals Corporation (Nasdaq:TKMR) (TSX:TKM), a leading developer of RNA interference (RNAi) therapeutics, announced today an update from the Company's Analyst and Investor Day, which took place on November 21 in New York City. The event highlighted Tekmira's key products and clinical development plans, as well as corporate milestones for 2015 and beyond.

Key highlights from the meeting included the following:

  • The Company announced its first regulatory filing, in the form of a Clinical Trial Application (CTA) filed with Health Canada, to support its first TKM-HBV clinical trial.
    • Human trials are expected to commence in early 2015, progressing to chronically infected patients in a multi-dosing regimen in the second half of 2015
  • The Company introduced a new 'fourth generation' LNP, exhibiting significant increases in potency.
    • Two TKM-HBV product candidates will enter Phase I trials in early 2015. Both product candidates will employ the same RNAi triggers but differ based on the version of LNP used in delivery (i.e. third or fourth generation)
    • It is anticipated that proof-of-concept data for HBV surface antigen knockdown could potentially be available in 2015
  • Tekmira announced completion of patient enrolment in the Phase I/II trial of TKM-PLK1 for the treatment of Gastrointestinal Neuroendocrine Tumors (GI-NET) or Adrenocortical Carcinoma (ACC) tumors.
    • The Company remains on track to disclose interim data before the end of 2014
    • Final data for these studies is expected in mid-2015

"Tekmira has been at the forefront of the RNAi industry for the last decade, and 2014 has been a pivotal year for the Company as we continue to advance our pipeline of proprietary products to maximize value for our shareholders. In the year ahead, we intend to initiate and complete a Phase I study with TKM-HBV, participate in human clinical studies with TKM-Ebola-Guinea, release interim HCC data and full data for Phase I/II PLK1 trials in GI-NET and ACC, and file for an IND, or equivalent, for our next development candidate," said Dr. Mark J. Murray, Tekmira's President and CEO.

About RNAi and Tekmira's LNP

RNAi therapeutics have the potential to treat a number of human diseases by "silencing" disease causing genes. The discoverers of RNAi, a gene silencing mechanism used by all cells, were awarded the 2006 Nobel Prize for Physiology or Medicine. RNAi trigger molecules often require delivery technology to be effective as therapeutics. Tekmira believes its LNP technology represents the most advanced and widely adopted delivery technology for the systemic delivery of RNAi triggers. Tekmira's LNP platform is being utilized in multiple clinical trials in various disease areas by Tekmira and its partners. Tekmira's LNP technology (formerly referred to as stable nucleic acid-lipid particles or SNALP) encapsulates RNAi triggers with high efficiency in uniform lipid nanoparticles that are effective in delivering these therapeutic compounds to disease sites. Tekmira's LNP formulations are manufactured by a proprietary method which is robust, scalable and highly reproducible, and LNP-based products have been reviewed by multiple regulatory agencies for use in clinical trials. LNP formulations comprise several lipid components that can be adjusted to suit the specific application.
