Tekmira Provides Corporate Update and Announces Third Quarter 2011 Results

Conference Call at 4:30 pm Eastern Time Today

VANCOUVER, British Columbia, Nov. 8, 2011 (GLOBE NEWSWIRE) -- Tekmira Pharmaceuticals Corporation (Nasdaq:TKMR) (TSX:TKM), a leading developer of RNA interference (RNAi) therapeutics, announced its financial and operational results for the third quarter ended September 30, 2011.

"Over the past quarter, we have focused on our core business and made progress with the expanded clinical development of TKM-PLK1 and advancement of TKM-Ebola towards a Phase 1 clinical trial. Our lipid nanoparticle delivery technology continues to lead the RNAi field by supporting multiple clinical candidates from Tekmira and our partners. The next few quarters represent an exciting time for the RNAi field when we will see multiple clinical data points from our TKM-PLK1 product and other products enabled by our technology, including Alnylam's ALN-TTR and ALN-PCS product candidates," said Dr. Mark J. Murray, Tekmira's President and CEO.

Corporate Update and Third Quarter Highlights

• A Phase 1 human clinical trial for TKM-PLK1 is ongoing. TKM-PLK1 targets polo-like kinase 1, or PLK1, a cell cycle protein involved in tumor cell proliferation and a validated oncology target. In December 2010, Tekmira initiated a TKM-PLK1 Phase 1 clinical trial, which is being conducted at three medical centers in the United States. The trial is an open label, multi-dose, multi-cycle, dose-escalation study designed to evaluate the safety, tolerability and pharmacokinetics of TKM-PLK1 and determine the maximum tolerated dose in patients with advanced solid tumors.
  
  This past quarter, Tekmira received approval from the United States Food and Drug Administration (FDA) to proceed with a new Phase 1 clinical trial for TKM-PLK1 in collaboration with its partners at the United States National Cancer Institute (NCI) and patient enrollment has commenced. This clinical trial will employ a route of administration of TKM-PLK1 directly into the liver via Hepatic Artery Infusion (HAI) in patients with liver metastases. This allows for direct measurement of tumor delivery, PLK1 knockdown, and RNAi activity in tumor biopsies.
   
• Tekmira continues to develop its TKM-Ebola product under a US$140 million contract awarded by the U.S. Government's Transformational Medical Technologies (TMT) Program. The TMT contract will support the development of TKM-Ebola through FDA approval. TKM-Ebola is on track for approval of an investigational new drug (IND) application in the second half of 2011 and initiation of a Phase 1 human clinical trial in the first quarter of 2012. Tekmira's work on the TKM-Ebola program also supports continued lipid nanoparticle (LNP) technology innovations around process development, manufacturing scale-up, and lyophilization.
   
• Tekmira, along with collaborators at SomaGenics, Inc. and Roche, presented data demonstrating – for the first time – in vivo efficacy of RNAi against the Hepatitis C virus (HCV). The data was presented at the 7th Annual Meeting of the Oligonucleotide Therapeutics Society (OTS) held September 8-10, 2011 in Copenhagen, Denmark.
   
• In August 2011, Tekmira obtained an exclusive, worldwide license to a novel and proprietary RNAi technology called MV-RNA (multivalent RNA) from Halo-Bio RNAi Therapeutics, Inc. (Halo-Bio). Halo-Bio's MV-RNA technology comprises single macromolecules capable of mediating RNAi at multiple unique target sites. MV-RNA can target three sites on a single gene or up to three separate genes simultaneously. Tekmira has successfully demonstrated multi-gene knockdown using MV-RNA enabled by proprietary LNP formulations.
   
• Tekmira's LNP technology is enabling the systemic RNAi product pipeline of Alnylam Pharmaceuticals, Inc. Tekmira continues to be the exclusive manufacturer of any LNP-based drug products required by Alnylam through to the end of Phase 2 clinical trials, including the products ALN-VSP, ALN-TTR and ALN-PCS. Alnylam provided the following guidance within its third quarter 2011 financial results:

• In August, Alnylam reported that they had completed treatment of patients in the Phase 1 study protocol for ALN-VSP, with some patients continuing treatment in the extension study. As of November, three patients with disease control continue to receive ALN-VSP under the extension protocol, including one endometrial cancer patient with an ongoing partial response who has now received drug for more than 17 months. ALN-VSP is a LNP-delivered RNAi therapeutic for the treatment of advanced solid tumors with liver involvement.
   
• ALN-TTR01 is currently enrolling patients in a blinded, randomized, placebo-controlled, single dose escalation Phase 1 clinical trial. Alnylam expects to present Phase 1 data later this month at the International Symposium on Familial Amyloidotic Polyneuropathy being held November 20 - 22, 2011 in Kumamoto, Japan.
   
• Alnylam has now initiated dosing in a Phase 1 trial with ALN-PCS targeting PCSK9 for the treatment of severe hypercholesterolemia. The trial is being conducted in the UK as a randomized, placebo-controlled, single-ascending dose study enrolling approximately 32 healthy voluntary subjects with elevated baseline LDL cholesterol. More detail and additional information about Alnylam's programs can be found at http://www.alnylam.com.

• Subsequent to quarter end, Tekmira provided a periodic update to the ongoing litigation with Alnylam and AlCana Technologies, Inc. Documents related to this lawsuit can be found on the Tekmira website at: www.tekmirapharm.com.
   
• In October 2011, Tekmira updated its financial guidance. Based on continued strong revenue from its collaboration partners as well as prudent management of its expenses, Tekmira now believes that its current funds on hand plus expected revenue will extend its cash runway to the end of 2012. This projection includes continued investment in the advancement of Tekmira's product candidates and its lipid nanoparticle technology as well as the conclusion of the ongoing Alnylam / AlCana litigation.

Financial results

Net Loss

For the first nine months of 2011, net loss was $8.1 million ($0.73 per common share) as compared to a net loss of $10.6 million ($1.02 per common share) for the first nine months of 2010. For Q3 2011, net loss was $1.5 million ($0.12 per common share) as compared to a net loss of $2.4 million ($0.24 per common share) for Q3 2010.

In general, losses have decreased with new revenue from the TKM-Ebola contract that started in July 2010. Revenue is a mix of compensation for staff time and overheads and reimbursement for research and development costs.

Revenue

Revenue was $4.2 million for Q3 2011 as compared to $10.4 million in Q3 2010.

In Q3 2010, Tekmira received a $5.9 million license amendment payment from Talon Therapeutics, Inc. (formerly Hana Biosciences, Inc.). The $5.9 million was then paid to certain contingent creditors in full settlement of a contingent obligation and therefore was also included as a "loss on the purchase and settlement of exchangeable and development notes" in Tekmira's Q3 2010 income statement expenses. Talon is developing targeted chemotherapy products under a legacy license agreement from Tekmira entered into in May 2006. Following the license amendment, Tekmira is eligible to receive milestone payments from Talon of up to US$19.0 million upon achievement of further development and regulatory milestones and is also eligible to royalties on product sales.

On July 14, 2010, Tekmira signed a contract with the United States Government to advance an RNAi therapeutic utilizing Tekmira's LNP technology to treat Ebola virus infection. Under the contract, Tekmira is being reimbursed for costs incurred, including an allocation of overheads, and is being paid an incentive fee. Tekmira recorded $2.0 million in revenue from this contract in Q3 2011.

Alnylam contract revenue was $1.4 million in Q3 2011 and $1.8 million in Q3 2010. Under an Alnylam Manufacturing Agreement there is a contractual minimum payment for the provision of staff in each of the three years from 2009 to 2011 and Alnylam is reimbursing Tekmira for any external costs incurred. Tekmira also recorded $0.5 million in milestone revenue in Q3 2011 when Alnylam initiated a Phase 1 human clinical trial for ALN-PCS. ALN-PCS is manufactured by Tekmira and is enabled by Tekmira's LNP delivery technology.

Research, development, collaborations and contracts expenses

Research, development, collaborations and contracts expenses were $4.4 million in Q3 2011 as compared to $5.2 million in Q3 2010. In Q3 2010 Tekmira incurred more costs related to batch manufacture for Alnylam than in Q3 2011. Also, in Q3 2010 Tekmira paid out staff bonuses following the award of the TKM-Ebola contract. No bonuses have been paid in 2011.

General and administrative

General and administrative expenses were $1.2 million in Q3 2011 as compared to $1.5 million in Q3 2010. Q3 2010 general and administrative expenses were higher than usual as they included costs related to Tekmira's NASDAQ share listing.

2011 financial guidance

At September 30, 2011, Tekmira had cash and cash equivalents of approximately $9.2 million as compared to $12.3 million at December 31, 2010. In Q2 2011, Tekmira completed an equity offering, raising gross proceeds of $5.1 million. Following the financing, Tekmira now believes that its current funds on hand plus expected income, including funds from collaborative partners and the U.S. Government, will be sufficient to continue product development until the end of 2012.

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.

About Tekmira

Tekmira Pharmaceuticals Corporation is a biopharmaceutical company focused on advancing novel RNAi therapeutics and providing its leading lipid nanoparticle delivery technology to pharmaceutical partners. Tekmira has been working in the field of nucleic acid delivery for over a decade and has broad intellectual property covering LNPs. Further information about Tekmira can be found at www.tekmirapharm.com. Tekmira is based in Vancouver, B.C.
