If I read the press release correctly, a single 4 ml dose was effective for 20 weeks; that is 5 months or 140 days!!! This is incredible!!! Think what this means for the patients, a single dose keeps on giving for weeks after weeks, months after months. I'd love to see if it ever stops and when a second dose would be necessary, if ever. This would be the only OAK drug that doctors will prescribe and the only drug the insurance companies will pay for. The economics are simple, a win win for the patients, the insurance companies and Ampio. This is huge, go AMPE!!!!
