Tekmira Pharmaceuticals Amends Agreement With Legacy Partner Hana Biosciences

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 21, 2010) - Tekmira Pharmaceuticals Corporation (TSX:TKM), a leader in RNA interference (RNAi) therapeutics, announced today that is has amended its license agreement with Hana Biosciences, Inc. Tekmira licensed three legacy chemotherapy product candidates to Hana in 2006. Hana is responsible for all expenses associated with the development of the product candidates and Tekmira is eligible to receive milestones and royalties. Tekmira is focused on advancing novel RNAi product candidates and providing its leading lipid nanoparticle (LNP) delivery technology to pharmaceutical partners.

Under the terms of the amendment, Hana will make a US$5.75 million payment to Tekmira in consideration for reducing certain future payments associated with the product candidates. Tekmira will transfer the US$5.75 million to former debt holders of Tekmira which will eliminate all future payments to the former debt holders.

Dr. Mark J. Murray, Tekmira's President and CEO, said, "We are pleased to amend our agreement with Hana, and in the process, eliminate any future obligations to our former debt holders. We remain focused on the advancement of our internal RNAi product candidates and providing our leading lipid nanoparticle delivery technology to our global pharmaceutical partners." 

Background to Hana License Agreement and Debt Settlement

In 2006, Tekmira licensed three legacy chemotherapy product candidates, Marqibo, Alocrest and Brakiva to Hana. After completion of the Hana license agreement, in 2006, Tekmira entered into a settlement agreement with former debt holders of the Company. As part of the settlement agreement, the former debt holders received an upfront payment and were to receive up to US$22.8 million in future payments based on Tekmira receiving payments from Hana.

Concurrent with the amendment to the Hana license agreement, Tekmira has entered into an agreement with its former debt holders. The payment of US$5.75 million will eliminate all future payments to the former debt holders.

Tekmira has the opportunity to receive additional milestones and royalties on product sales from Hana based on the successful development of Marqibo, Alocrest and Brakiva.

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. LNP technology is one of the most widely used siRNA delivery approaches for systemic administration. Tekmira's LNP technology (formerly referred to as stable nucleic acid-lipid particles or SNALP) encapsulates siRNAs with high efficiency in uniform lipid nanoparticles which 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.

With respect to the forward-looking statements contained in this news release, Tekmira has made numerous assumptions regarding, among other things: LNP's status as a leading RNAi delivery technology; Tekmira's research and development capabilities and resources; the timing and obtaining of regulatory approvals for Tekmira's products; and the time required to complete research and product development activities. While Tekmira considers these assumptions to be reasonable, these assumptions are inherently subject to significant business, economic, competitive, market and social uncertainties and contingencies.

Additionally, there are known and unknown risk factors which could cause Tekmira's actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements contained herein. Known risk factors include, among others: the possibility that other organizations have made advancements in RNAi delivery technology that Tekmira is not aware of; the FDA will not approve the commencement of Tekmira's planned clinical trials or approve the use of Tekmira's products and generally, difficulties or delays in the progress, timing and results of clinical trials and studies; anticipated payments under contracts with Tekmira's collaborative partners, including Hana, will not be received by Tekmira on a timely basis, or at all, or in the quantum expected by Tekmira; pre-clinical trials may not be completed, or clinical trials started, when anticipated or at all; pre-clinical and clinical trials may be more costly or take longer to complete than anticipated; pre-clinical or clinical trials may not generate results that warrant future development of the tested drug candidate.

A more complete discussion of the risks and uncertainties facing Tekmira appears in Tekmira's Annual Information Form dated March 31, 2010 available at www.sedar.com. All forward-looking statements herein are qualified in their entirety by this cautionary statement, and Tekmira disclaims any obligation to revise or update any such forward-looking statements or to publicly announce the result of any revisions to any of the forward-looking statements contained herein to reflect future results, events or developments, except as required by law.
