Tekmira Reports New Interim Clinical Data From TKM-PLK1 Oncology Phase 1 Clinical Trial
Conference Call at 4:30 pm Eastern Time Today
VANCOUVER, B.C., Aug. 14, 2012 (GLOBE NEWSWIRE) -- Tekmira Pharmaceuticals Corporation (Nasdaq:TKMR) (TSX:TKM), a leading developer of RNA interference (RNAi) therapeutics, announced today its financial and operating results for the second quarter ended June 30, 2012 and provided a corporate update.
"Over the past few months, significant clinical data have been reported providing further validation that Tekmira's LNP technology is the 'gold standard' and most widely-used delivery technology in the RNAi field. Building on this momentum, we are releasing interim TKM-PLK1 results demonstrating that TKM-PLK1 is showing promising signs of drug activity in an ongoing Phase 1 human clinical trial," said Dr. Mark J. Murray, Tekmira's President and CEO.
"We believe Tekmira is entering the second half of the year in a solid position, bolstered by positive RNAi clinical data and the recent news that Talon was granted accelerated approval for Marqibo, which triggered a milestone payment to Tekmira. The Court's decision in July to deny Alnylam and AlCana's requests to file motions for summary judgment means that the ongoing litigation will proceed to trial on all counts this fall – and all issues will be decided by a jury," added Dr. Murray.
TKM-PLK1 Phase 1 Clinical Data
"We are very encouraged with the interim results from our ongoing Phase 1 human clinical trial for TKM-PLK1 in an advanced and heavily pre-treated population of cancer patients with solid tumors. TKM-PLK1 is being dosed on an aggressive once weekly protocol and the drug has been generally well tolerated. In addition, we have seen encouraging signs of drug activity with one patient achieving a 63% reduction in tumor burden (partial response) and who remains on study after receiving 15 doses of drug over 5 months, and another patient achieving stable disease who received 18 doses of TKM-PLK1 over 6 months," added Dr. Murray.
In December 2010, Tekmira announced the initiation of patient dosing in a Phase 1 human clinical trial for TKM-PLK1 in patients with advanced solid tumors. The Phase 1 clinical trial, conducted at oncology centers in the United States, is an open label, multi-dose, dose escalation study designed to evaluate the safety, tolerability and pharmacokinetics of TKM-PLK1 as well as determine the maximum tolerated dose. Secondary objectives of the trial are to measure tumor response and the pharmacodynamic effects of TKM-PLK1 in patients providing biopsies.
Interim results from this Phase 1 study, employing a unique LNP developed for oncology applications, show that TKM-PLK1 was generally well tolerated. To date, TKM-PLK1 has been administered to 21 patients at doses ranging from 0.15 mg/kg to 0.90 mg/kg; a total of 105 doses have been administered. Patients are dosed on an aggressive once weekly protocol with each cycle consisting of three doses followed by a rest week. Pharmacokinetic data from this study showed that Cmax (peak serum concentration of drug) and area under the curve (AUC) were dose proportional, with no evidence of drug accumulation, and that the pharmacokinetic profile of TKM-PLK1 is maintained through multiple cycles of treatment. Pre-clinical animal pharmacokinetic data were predictive for the observed results in man. Importantly, the data confirm that the drug exposure levels achieved in this trial, incorporating Tekmira's proprietary LNP formulation specifically designed to facilitate siRNA delivery to disseminated disease sites, are several fold greater than were achieved in clinical trials using earlier LNP formulations. The most common grade 1-2 adverse events were nausea and fever/chills. There were no dose-dependent changes in liver function tests. Grade 2 infusion-related reactions were observed in 19% of patients. Dose-limiting toxicities observed to date include transient thrombocytopenia in one patient (at 0.9 mg/kg) and hypoxia/dyspnea in one patient (at 0.9 mg/kg). Based on these data, patient enrollment is continuing at 0.75 mg/kg. Once complete, results from the Phase 1 clinical trial, including additional measures of drug activity, will be presented at forthcoming scientific meeting.
TKM-Ebola Update
On August 6, 2012, Tekmira announced that it received a temporary stop-work order from the U.S. Department of Defense (DoD) with respect to Tekmira's TKM-Ebola program, which is funded under the Transformational Medical Technologies (TMT) Program. Other contractors have received similar notices due to recently imposed funding constraints at the DoD. Tekmira expects a decision by September 1, 2012 on the future direction of the TMT collaboration, at which time the DoD may cancel the stop-work order; terminate the contract; or extend the stop-work order period, if necessary.
The TKM-Ebola Phase 1 human clinical trial, which is a placebo-controlled, single-blind, single-ascending dose study with additional multiple-ascending dose cohorts in healthy human volunteers, is ongoing. The objective of the Phase 1 trial is to assess the safety and tolerability of TKM-Ebola and evaluate the pharmacokinetics and systemic exposure following both a single-ascending dose and multiple-ascending doses of TKM-Ebola. Tekmira is developing its TKM-Ebola product under a US$140 million contract awarded by the U.S. Government's TMT Program. The TKM-Ebola program also supports continued LNP technology innovations around process development, manufacturing scale-up, and lyophilization.
Litigation Update
Tekmira has filed a lawsuit against Alnylam Pharmaceuticals, Inc. and AlCana Technologies, Inc. in the Business Litigation Session of the Massachusetts Superior Court alleging misappropriation of our confidential information related to our proprietary lipid nanoparticle technology, resulting in damage to our intellectual property and business interests. Alnylam and AlCana have responded to our complaint and have filed counterclaims. On July 17, 2012, Tekmira provided another periodic update to the ongoing litigation with Alnylam and AlCana. Recent developments include:
In January 2012, the Supreme Court of British Columbia granted an injunction against certain individuals from AlCana, ordering them to cease using Tekmira's confidential information and return all of the documents stolen from Tekmira.
Partners' Products
Tekmira's LNP technology is enabling Alnylam's systemic RNAi product pipeline. Alnylam has an obligation to use Tekmira as the exclusive manufacturer of any LNP-based drug products required by Alnylam through to the end of Phase 2 clinical trials. Over the past quarter, more data were released confirming RNAi proof-of-concept has been achieved in humans using Tekmira's LNP technology.
On August 9, 2012, Tekmira disclosed that its licensing partner, Talon Therapeutics, Inc., received accelerated approval from the U.S. Food and Drug Administration (FDA) for Marqibo® (vinCRIStine sulfate LIPOSOME injection) for the treatment of adult patients with Philadelphia chromosome negative (Ph-) acute lymphoblastic leukemia (ALL) in second or greater relapse or whose disease has progressed following two or more anti-leukemia therapies. Marqibo is a liposomal formulation of the chemotherapy drug vincristine. Marqibo, along with two other liposomal chemotherapy products, Alocrest (liposomal formulation of the chemotherapy drug vinorelbine) and Brakiva (liposomal formulation of the chemotherapy drug topotecan), were licensed from Tekmira to Talon (formerly Hana Biosciences) in 2006. Talon is responsible for all future development of these products. Tekmira will receive US$1M milestone payment based on the FDA approval of Marqibo and will receive royalty payments based on Marqibo's commercial sales.
Financial Results
Net Loss
For the first half of 2012 the Company's net loss was $5.1 million ($0.38 per common share) as compared to a net loss of $6.6 million ($0.63 per common share) for the first half of 2011. For Q2 2012 the Company's net loss was $1.9 million ($0.14 per common share) as compared to a net loss of $3.5 million ($0.33 per common share) for Q2 2011.
Revenue
Revenue was $3.6 million for Q2 2012 as compared to $4.4 million in Q2 2011.
On July 14, 2010, Tekmira signed a contract with the United States Government to advance an RNAi therapeutic utilizing the 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. U.S. Government revenue was $2.5 million in Q2 2012 as compared to $3.3 million in Q2 2011.
On August 6, 2012, the Company announced that it had received a temporary stop-work order from the U.S. Government in respect of its TKM-Ebola contract. It is expected that by September 1, 2012, Tekmira will receive notification from the U.S. Government on whether they will cancel the stop-work order; terminate the contract; or extend the stop-work order period, if necessary.
In Q2 2012, Tekmira earned a US$1.0 million milestone from Alnylam following their initiation of Phase 2 human clinical trials for ALN-TTR02. ALN-TTR02 utilizes Tekmira's LNP technology and the drug is being manufactured by Tekmira. The milestone was paid in July 2012.
Research, development, collaborations and contracts expenses
Research, development, collaborations and contracts expenses were $3.6 million in Q2 2012 as compared to $6.2 million in Q2 2011.
Third-party expenses on the TKM-Ebola program and Alnylam manufacturing were considerably lower in Q2 2012 as compared to Q2 2011.
Spending on Tekmira's internal research programs has been reduced as the Company focuses on TKM-Ebola, TKM-PLK1 as well as its litigation against Alnylam and AlCana.
General and administrative expenses
General and administrative expenses were $2.4 million in Q2 2012 as compared to $1.6 million in Q2 2011.
The increase in Q2 2012 largely relates to legal fees incurred in respect of Tekmira's lawsuit against Alnylam and AlCana. However, from March 2012 onwards, under a fixed monthly fee agreement with Tekmira's lead legal counsel for the lawsuit against Alnylam and AlCana, Tekmira will only be required to reimburse its lead counsel for expenses incurred but no further payments will be required for professional fees. If Tekmira is successful in this lawsuit, a fee will be paid to its lead counsel. At June 30, 2012, the contingent obligation was a minimum of $12.8 million (US$12.5 million).
Other income (losses) - change in fair value of warrant liability
In conjunction with equity and debt financing transactions in 2011 and an equity private placement that closed on February 29, 2012, Tekmira has issued common share purchase warrants. Under Tekmira's accounting policy, at each balance sheet date, the warrants are revalued using the Black-Scholes model and the change in value is recorded in the consolidated statement of operations and comprehensive loss. The aggregate decrease in value of Tekmira's common share purchase warrants in Q2 2012 was $0.6 million. The decrease is largely a result of the decrease in the Company's share price from the previous balance sheet date of March 31, 2012.
Financial guidance
As disclosed in the Company's 2011 year end MD&A, Tekmira believes that current funds on hand, plus expected income, including funds from collaborative partners and the U.S. Government and access to a US$3.0 million loan facility from Silicon Valley Bank, will be sufficient to continue product development into the second half of 2013.

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.
