Tekmira Presents Positive Interim Results on Phase I/II Clinical Programs
Confirms Safety Profile of Third Generation LNP
VANCOUVER, British Columbia, May 21, 2014 (GLOBE NEWSWIRE) -- Tekmira Pharmaceuticals Corporation (Nasdaq:TKMR) (TSX:TKM), a leading developer of RNA interference (RNAi) therapeutics, announced that recent advances in its clinical programs were presented at the 17th Annual Meeting of the American Society of Gene and Cell Therapy, which is taking place in in Washington, DC, May 21 to 24.
"Today, Dr. Ian MacLachlan presented positive clinical data which further validates our LNP technology and demonstrates progress within both our anti-viral and oncology programs. The TKM-Ebola phase I trial results are significant as they establish the safety of 'third generation' LNP formulations and confirm that dosing at efficacious levels may be accomplished without the need for pre-medication. We are encouraged by these technology advances and they will support the development of Tekmira's other anti-viral therapeutics," said Dr. Mark J. Murray, Tekmira's President and CEO.
The presentation titled "Progress in the Development of Lipid Nanoparticle-RNA Therapeutics" was delivered by Tekmira's Chief Technical Officer, Dr. Ian MacLachlan. During the presentation, Dr. MacLachlan shared new interim data from the ongoing TKM-Ebola Phase I Clinical Trial and the Phase I/II Clinical Trial with TKM-PLK1.
Some key summary points from the presentation include:
TKM-Ebola
- Tekmira has successfully completed the single ascending dose portion of the TKM-Ebola Phase I Clinical Trial in healthy human volunteers.
- Results demonstrate that administration of the TKM-Ebola therapeutic, in the absence of any steroid containing pre-medication, was well-tolerated at a dose level of 0.3 mg/kg.
- TKM-Ebola drug exposure levels achieved in these subjects demonstrate that the multiple ascending dose portion of the trial will achieve drug exposure levels previously shown to confer complete protection in non-human primates exposed to a lethal Ebola virus inoculum.
- Both the safety profile and pharmacokinetics observed in the single dose portion of the trial support initiation of the multiple ascending dose portion of the study
TKM-PLK1
- Tekmira previously disclosed (October 2013) three of four Adrenocortical Carcinoma (ACC) patients participating in the company's ongoing GI-NET/ACC trial had achieved stable disease.
- One of these patients is continuing on therapy and has achieved a RECIST qualifying Partial Response (PR), defined as >30% reduction in target tumor lesions.
- This patient with the PR has been on TKM-PLK for 12 months and has experienced a 44% reduction in their target tumor mass, located outside of the liver. Furthermore, scans of the target tumor lesions demonstrate signs of necrosis, indicative of anti-tumor activity.

About RNAi and Tekmira's LNP
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 the TKM-Ebola Phase I Clinical Trial
The TKM-Ebola Phase I clinical trial is a randomized, single-blind, placebo-controlled study involving single ascending doses and multiple ascending doses of TKM-Ebola. The study is assessing the safety, tolerability and pharmacokinetics of administering TKM-Ebola to healthy adult subjects. Tekmira expects to complete the Phase I clinical study in the second half of the year.
About TKM-Ebola, an Anti-Ebola Virus RNAi Therapeutic
TKM-Ebola, an anti-Ebola virus RNAi therapeutic, is being developed under a $140 million contract with the U.S. Department of Defense's Medical Countermeasure Systems BioDefense Therapeutics (MCS-BDTX) Joint Product Management Office. Earlier preclinical studies were published in the medical journal The Lancet and demonstrated that when siRNA targeting the Ebola virus and delivered by Tekmira's LNP technology were used to treat previously infected non-human primates, the result was 100 percent protection from an otherwise lethal dose of Zaire Ebola virus (Geisbert et al., The Lancet, Vol 375, May 29, 2010).
About Joint Project Manager Medical Countermeasure Systems (JPM-MCS)
This work is being conducted under contract with the U.S. Department of Defense Joint Project Manager Medical Countermeasure Systems (JPM-MCS). JPM-MCS, a component of the Joint Program Executive Office for Chemical and Biological Defense, aims to provide U.S. military forces and the nation with safe, effective, and innovative medical solutions to counter chemical, biological, radiological, and nuclear threats. JPM-MCS facilitates the advanced development and acquisition of medical countermeasures and systems to enhance our nation's biodefense response capability.

About TKM-PLK1
Tekmira's lead oncology product candidate, TKM-PLK1, targets polo-like kinase 1 (PLK1), a protein involved in tumor cell proliferation and a validated oncology target. Inhibition of PLK1 expression prevents the tumor cell from completing cell division, resulting in cell cycle arrest and death of the cancer cell. PLK1 has been a target of interest for years, and evidence that patients with elevated levels of PLK1 in their tumors exhibit poorer prognosis and survival rates has been documented in the medical literature. By using an RNAi approach and exploiting its naturally occurring mechanism of action, Tekmira can potentially overcome the limitations of other approaches and effectively silence PLK1.
About the TKM-PLK1 Phase I/II Clinical Trial
The ongoing TKM-PLK1 Phase I/II clinical trial, which is currently targeting GI-NET and ACC patients for enrollment, is a multi-center, single arm, open label study designed to measure efficacy using RECIST and tumor biomarkers for GI-NET patients, as well as to evaluate TKM-PLK1's safety, tolerability and pharmacokinetics. TKM-PLK1, which employs a unique lipid nanoparticle (LNP) formulation for oncology applications, will be administered weekly with each four-week cycle consisting of three once-weekly doses followed by a rest week. It is expected that approximately 20 patients with advanced GI-NET or ACC tumors will be enrolled in this trial, with a minimum of 10 GI-NET patients to be enrolled.
