EXHIBIT 99.1

Tekmira and Alnylam Restructure Relationship and Settle All Litigation

VANCOUVER, British Columbia, Nov. 12, 2012 (GLOBE NEWSWIRE) -- Tekmira Pharmaceuticals Corporation (Nasdaq:TKMR) (TSX:TKM) today announced that it has entered into a settlement agreement with Alnylam Pharmaceuticals, Inc. that resolves all litigation between the companies, and has signed a new licensing agreement that restructures the relationship and provides clarity on all intellectual property and licensing issues between the companies. As a result of the restructuring and new agreements, Tekmira will receive $65 million within 10 days and is eligible to receive $10 million in near-term milestone payments expected to be received in 2013.

"Today's announcement provides assurances for our stakeholders that we accomplished what we set out to do when we initiated this litigation. We now have clarity around the intellectual property that protects our lipid nanoparticle (LNP) technology and a cash payment that will enable us to continue the execution of our business plan into 2015," said Dr. Mark J. Murray, Tekmira's President and CEO.

"Tekmira is entering an exciting new era of growth and development. Clarity of rights and ownership around our LNP intellectual property – the leading technology for the systemic delivery of RNAi therapeutics – combined with a strong balance sheet should strengthen our ability to invest in, advance and expand our own product pipeline. We also look forward to establishing new business relationships with pharmaceutical partners driven by intellectual property certainty and recent promising clinical data validating the therapeutic utility of LNP-enabled products," added Dr. Murray.

As part of this settlement and restructuring, all previous agreements between the companies are terminated and a new license agreement has been established that provides clear terms outlining Tekmira's LNP intellectual property. Under the terms of the new license agreement:

• Alnylam will transfer all agreed-upon patents and patent applications related to LNP technology for the systemic delivery of RNAi therapeutic products, including the MC3 lipid family, to Tekmira, who will own and control prosecution of this intellectual property portfolio. Tekmira is the only company able to sublicense LNP intellectual property in future platform-type relationships.
   
• Tekmira will receive a total of $65 million in cash payments within 10 days. This includes $30 million associated with the termination of the manufacturing agreement and $35 million associated with the termination of the previous license agreements, as well as a modification of the milestone and royalty schedules associated with Alnylam's ALN-VSP, ALN-PCS, and ALN-TTR02 programs.
   
• Tekmira is also eligible to receive an additional $10 million in near-term milestones, comprised of a $5 million payment upon ALN-TTR02 entering a pivotal trial and a $5 million payment related to initiation of clinical trials for ALN-VSP in China. Both near-term milestones are expected to occur in 2013.
   
• Alnylam no longer has "opt-in" rights to Tekmira's lead oncology product, TKM-PLK1; Tekmira now holds all development and commercialization rights related TKM-PLK1, which is expected to enter Phase 2 clinical trials in 2013.
   
• In addition to its eight existing InterfeRx licenses, Tekmira will receive five additional non-exclusive licenses to develop and commercialize RNAi therapeutics based on Alnylam's siRNA payload technology. Tekmira will pay Alnylam milestones and royalties for these products.
   
• Alnylam has a license to use Tekmira's intellectual property to develop and commercialize products, including ALN-TTR02, ALN-VSP, ALN-PCS, and other LNP-enabled products. Alnylam has rights to sublicense Tekmira's LNP technology if it is part of a product sublicense. Tekmira remains eligible for milestone and royalty payments as Alnylam's LNP-enabled products are developed and commercialized.

Alnylam and Tekmira have agreed to settle all ongoing litigation between the parties. The parties have also agreed to a resolution of the interference proceeding related to Alnylam-owned US Patent No. 7,718,629 directed to an siRNA component in ALN-VSP. Finally, the parties have agreed to a covenant not to sue on matters related to the current dispute in the future, which includes liquidated damages to be paid if the covenant is breached, and have also agreed to resolve any future disputes that might arise over the next three years with binding arbitration.

Tekmira and AlCana Technologies, Inc. have also agreed to settle all ongoing litigation between the parties. Tekmira expects to enter into a cross license agreement with AlCana which will include milestone and royalty payments, and AlCana has agreed not to compete in the RNAi field for five years.

About RNAi and Tekmira's LNP Technology

RNAi therapeutics have the potential to treat a broad 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 therapeutics, such as "siRNAs," require delivery technology to be effective systemically. Tekmira believes its LNP technology represents the most widely adopted delivery technology for the systemic delivery of RNAi therapeutics. Tekmira's LNP platform is being utilized in multiple clinical trials by both Tekmira and its partners. Tekmira's LNP technology (formerly referred to as stable nucleic acid-lipid particles or SNALP) encapsulates siRNAs with high efficiency in uniform lipid nanoparticles that are effective in delivering RNAi therapeutics to disease sites in numerous preclinical models. 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 FDA divisions for use in clinical trials. LNP formulations comprise several lipid components that can be adjusted to suit the specific application.

About Alnylam RNAi Technology

Tekmira has licenses to Alnylam RNAi intellectual property for certain siRNA programs.
