FDA Authorizes Tekmira to Provide Treatment to Subjects with Confirmed/Suspected Ebola Virus Infections

Tekmira Pharmaceuticals Corporation, a leading developer of RNA interference (RNAi) therapeutics, today announced that the FDA has authorized Tekmira to provide TKM-Ebola for treatment under expanded access protocols to subjects with confirmed or suspected Ebola virus infections.

"Tekmira is reporting that an appropriate regulatory and clinical framework is now in place to allow the use of TKM-Ebola in patients. We have worked with the FDA and Health Canada to establish this framework and a treatment protocol allowing us to do what we can to help these patients," said Dr. Mark J. Murray Tekmira's President and CEO.

"We have insisted on acting responsibly in the interest of patients and our stakeholders," added Dr. Murray. "Today we are reporting that, working closely with regulators in the United States and Canada, we have established a framework for TKM-Ebola use in multiple patients. In the US, the FDA has granted expanded access use of TKM-Ebola under our Investigational New Drug application (IND) and Health Canada has established a similar framework, both of which allow the use of our investigational therapeutic in more patients."

"We have already responded to requests for the use of our investigational agent in several patients under emergency protocols, in an effort to help these patients, a goal we share with the FDA and Health Canada. TKM-Ebola has been administered to a number of patients and the repeat infusions have been well tolerated. However, it must be kept in mind that any uses of the product under expanded access, does not constitute controlled clinical trials. These patients may be infected with a strain of Ebola virus which has emerged subsequent to the strain that our product is directed against, and physicians treating these patients may use more than one therapeutic intervention in an effort to achieve the best outcome," said Dr. Murray. "Our TKM-Ebola drug supplies are limited, but we will continue to help where we can, as we continue to focus on the other important objectives we have to advance therapies to meet the unmet needs of patients."

TKM-Ebola is an investigational therapeutic, being developed under an FDA approved IND, which is currently the subject of a partial clinical hold under which the FDA has allowed the potential use of TKM-Ebola in individuals with a confirmed or suspected Ebola virus infection.

About FDA Expanded Access Program

Expanded access is the use of an investigational drug outside of a clinical trial to treat a patient, with a serious or immediately life-threatening disease or condition, who has no comparable or satisfactory alternative treatment options. FDA regulations allow access to investigational drugs for treatment purposes on a case-by-case basis for an individual patient, or for intermediate-size groups of patients with similar treatment needs who otherwise do not qualify to participate in a clinical trial.

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). In March 2014, Tekmira was granted a Fast Track designation from the U.S. Food and Drug Administration for the development of TKM-Ebola.
