Posters Presented at the Interscience Conference on Antimicrobial Agents and Chemotherapy
PORTLAND, OR, USA | Sep 29, 2006 | AVI BioPharma, Inc. (Nasdaq: AVII), today presented preclinical data regarding the use of its NeuGene® antisense technology against influenza A and E. coli infection. The data was presented in two posters at the 46th Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) meetings held in San Francisco.
The first presentation, titled “Inhibition of Several Subtypes of Influenza A Virus with Antisense Morpholino Oligomers,” was presented by AVI collaborators from Oregon State University and included data from collaborators at the Massachusetts Institute of Technology; the Public Health Agency of Canada in Winnipeg; and Mahidol University in Bangkok, Thailand. The data showed that two AVI antisense compounds inhibited several strains of influenza A, including the avian strain H5N1 in cell culture as previously reported. Experiments in mice are ongoing.
The second presentation, titled “Antisense Phosphorodiamidate Morpholino Oligomer–Peptide Conjugate: Dose–Response in Mice Infected with Escherichia Coli,” was presented by AVI scientist Bruce Geller, Ph.D. The data showed that the AVI antisense compounds promoted survival in mice infected with E. coli. These antisense compounds, referred to as NeuBiotics, reduced bacteremia in mice by three orders of magnitude compared with controls.
“We believe that the diverse applications of our NeuGene antisense technology exhibited by these presentations suggest that our technology holds promise for broad utility in battling infectious diseases,” said Patrick L. Iversen, Ph.D., senior vice president of research and development at AVI. “By targeting regions of the viral genetic code that are common to all influenza A subtypes, we expect that our NeuGene drugs will be effective against avian flu and the far more common seasonal influenza viruses. Owing to the events of the past several weeks, we are acutely aware of the importance of developing new strategies for combating troublesome bacterial infections like E. coli.”
