Powdermed’s PMED “GENE Gun” NAMED TO THE POPULAR SCIENCE® “BEST OF WHAT’S NEW” FOR 2005 Needle-free Device for DNA Vaccine Drug Delivery Awarded Prestigious Honour in the Personal Health Category; Avian Flu Vaccine First BioDefense Application
OXFORD, ENGLAND and FREDERICK, MD, US. 8 November 2005 - PowderMed, an immunotherapeutics company focused on the development and manufacture of DNA-based vaccines for viral diseases and cancer, announced today that its Particle Mediated Epidermal Delivery (PMEDTM) vaccine delivery device has been selected by the editors of Popular Science as one of this year’s top 100 breakthrough technologies. The publication has awarded the PMED device, commonly referred to as the “Gene Gun,” a 2005 Best of What’s New (BOWN) award in the Personal Health category. PMED is featured along with other winners in the magazine’s December issue. PowderMed is focused on the clinical development and manufacture of therapeutic and prophylactic DNA-based vaccines for viral diseases and cancer that leverage the PMED device for vaccine delivery.
PowderMed’s ground-breaking PMED device employs a proprietary technology platform that delivers gold micro-particles coated with DNA-based vaccine into the immune network of the outer layer of the skin (the epidermis), which is impossible to access using a needle and syringe. The targeting of this immune cell rich tissue means that immune responses are seen with very small (microgram) doses of DNA-based vaccine; a 1000-fold less than with intramuscular DNA injection. PowderMed’s lead clinical program is a DNA-based prophylactic vaccine to target annual and pandemic influenza as the technology has unique features to deal with the pandemic threat posed by H5N1 or avian flu. The company currently has four clinical and three late stage pre-clinical projects. "Best of What's New is the ultimate Popular Science accolade, representing a year's worth of work evaluating thousands of products," said Mark Jannot, editor of Popular Science. "These awards honour innovations that not only impact the way we live today, but change the way we think about the future.” The PMED device is a single-use, disposable device powered by high pressure helium. The cassette containing the powdered vaccine is loaded into the body of the device at the end of the manufacturing process. As the powdered vaccine is stable at ambient temperature and the cassette is sealed, PMED can be stored simply and cheaply.
A key difference between direct injection and PMED delivery is the efficiency with which this is done: Direct injection delivers the DNA to extracellular spaces and relies on an inefficient, non-specific uptake of the DNA by neighbouring cells or transport along lymphatic vessels to draining lymph nodes. In contrast, PMED delivers the DNA directly to the intracellular compartment. As a result, PMED delivery uses 1,000-fold less DNA than needle and injection administration, hence the cost per dose for PMED is commercially attractive.
“All of us at PowderMed are very proud to receive this recognition from such a highly respected publication. This award endorses much of the hard work that has gone into the development of the PMED device,” said PowderMed CEO Dr.Clive Dix. “With the PMED technology and our groundbreaking development of flu vaccines, we will have the fastest response to a pandemic, offering the best potential to save lives and minimize the economic impact.”
PowderMed has produced an H5N1 vaccine by cloning the H5 gene from the current circulating avian flu strain (“the gene cassette”) into the company’s proprietary DNA vaccine backbone and the vaccine is now ready for development. Manufacturing and toxicology studies are now in progress, and it is anticipated that this vaccine will enter clinical trials by the middle of 2006.
-END- About Best of What's New Each year, the editors of Popular Science review thousands of products in search of the top 100 tech innovations of the year -- breakthrough products and technologies that represent a significant leap in their categories. The winners -- The Best of What's New -- are awarded inclusion in the much-anticipated December issue of Popular Science, the most widely-read issue of the year since the birth of Best of What's New in 1987. Best of What's New awards are presented to 100 new products and technologies in 12 categories: Auto Tech, Aviation & Space, Cars, Computing, Engineering, Gadgets, General Innovation, Home Entertainment, Home Tech, Personal Health, Photography and Recreation. About Popular Science Founded in 1872, Popular Science is the world's largest science and technology magazine with a circulation of 1.45 million and 6.5 million monthly readers.

PowderMed is a private immunotherapeutic company based in Oxford, UK. The Company is focused on the clinical development and manufacture of therapeutic and prophylactic DNA-based vaccines for viral diseases and cancer. The company has 4 clinical and 3 pre-clinical stage projects. The lead clinical program has shown positive Phase I results in the treatment and prevention of human influenza. This technology is uniquely and easily adaptable to treat avian flu and to address the pandemic threat. PowderMed also has a product for the treatment of genital herpes in Phase I trials, and two partnered Phase I programs in Cancer (Ludwig Institute for Cancer Research) and HIV/AIDS (Glaxo SmithKline). PowderMed vaccines are delivered using PMEDTM (Particle Mediated Epidermal Delivery), a needle-free, painless delivery system that requires minimal medical training, allows self-administration and requires no refrigeration for stockpiling. Specifically, PowderMed’s technology delivers DNA to the epidermal layer of the skin where it is presented to the cells of the immune network, thereby creating immunity and thus facilitating both treatment and prevention of disease.
