A company called EnGeneIC in Sydney, Australia have created a targeted drug delivery platform based on “mini bacteria”, or as they call it, EnGeneIC Delivery Vehicles (EDVs). These vehicles look and behave like bacteria, including cell division — albeit, without chromosomes. I may need to dig a little deeper into the science of this one!
In any case, these EDVs have been shown to target tumorigenic tissue, being fed by blood vessels; 30% of an IV dosage reached the cancerous region within 2 hours. It has so far been proven safe in dogs with advanced non-Hodgkin’s lymphoma, as well as in pigs and monkeys.
The study also suggests that these EDVs can carry RNAi or siRNA-based products to their destination, as delivery of these nucleic acids has been proven difficult due to nuclease/enzymatic degredation before reaching its target.
