VANCOUVER, British Columbia, July 21, 2014 (GLOBE NEWSWIRE) -- Tekmira Pharmaceuticals Corporation (Nasdaq:TKMR) (TSX:TKM), a leading developer of RNA interference (RNAi) therapeutics, today announced an update on the TKM-Ebola Phase I clinical hold. The Company has received the clinical hold letter from the U.S. Food and Drug Administration (FDA) and is preparing a Complete Response to the Agency. The Company anticipates this matter will be resolved by Q4, 2014. Tekmira's other clinical development programs are unaffected by the TKM-Ebola clinical hold and all remain on track. The key milestones for these programs in the second half of 2014 are:
- Presentation of TKM-HBV Pre-Clinical data
- Filing IND (or equivalent) for TKM-HBV
- Interim Phase IIa TKM-PLK1 data
- Nomination of the next product development candidate
The Company is assembling the data requested by the FDA and shares its commitment to patient safety. Dr. Murray added, "The mechanism for cytokine release is understood and we will be modifying our study protocol to further ensure subject safety. Our team is working expediently to respond to the FDA. We are mindful of the need for this important therapeutic in situations such as the ongoing Ebola outbreak in West Africa. However, TKM-Ebola is currently an unapproved agent and the regulatory framework to support its use in Africa has not been established at this time."The Company will provide a full business update at the upcoming earnings release on August 13, 2014. About the TKM- Ebola Phase I Clinical Trial The TKM-Ebola Phase I clinical trial is a randomized, single-blind, placebo-controlled study and involves 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 volunteers without administering any steroid pre-medications. 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.
