RE:RE:Competition is Fierce ...Actually, that patch only lasts for 10 hours for mice according to that article. The Pharmacy company that partners with them would love that, making more money off patches. It most likely only lasts that long because the islets aren't in an environment to last long when out of the package and refrigerator and no blood supply. They actually initially had different patent last year with insulin attached to a soluable that releases only when blood sugar rising. But they ditched that plan and thought, why not add the actual insulin islet cells since they're so easy to make in a lab with stemcell growing. But I mention this also as a positive for Sernova, because ViaCyte's capsules will only last one year. So any diabetic would prefer a daily patch versus going under the knife for a surgery every year to have a bunch of new ViaCyte capsules taken out and reinserted every year. I believe this patch invention will wipe out any encapsulation cures that don't last longterm, such as Viacyte's. This would give Sernova's Cell Pouch the upper hand if able to survive long-term. Which is what they believe. We will know soon, as their next phase of human trials with Sertolin immunity protection will be added along with the islets into the pouch. Diabetics might be willing to deal with a surgery for new capsules if once every 5 years, instead of a daily patch. I'm hoping Sernova's Cell Pouch will be completely long-term lasting beyond 5 years. This would give Sernova a good comparison to base their pricing. If diabetics see that a daily patch is extremely expensive, they'll be willing to pay big bucks for a one-time procedures with no on-going costs and inconvenience. Plus other hormone therapy in the future... not just insulin.
