I think the most likely response from FDA is a denial to reclassify but they will get answers to limits of human testing need to get approval. A trial with a small number of people for a year or less is very possible. Even this will be a positive step. At least they will know what is required. I think you can expect large preferred share dump soon and some new investors willing to fund the trials.
Not likely going to happen anywhere near that fast. In a perfect world with a perfect application it may happen but odds say no way. One question and the process starts all over again. I also expect human trials will be required but its a big step in the right direction. Vet use is far more likely to progress much faster.
