Are there any current studies here or abroad to help the body create myelin sheath repair?
Yes there was some progress, however it has been stopped due to live failure. Results questionable. Hopefully there will be some progress in the near future.
NVG - 291 from Nervgen is the most promising that I have seen.
NERVGEN. CANADIAN Company with a new med and clinical trials.
The Biogen studies failed to reach a significant result and as far as I know, I don't believe any are ongoing currently. To look at Myelin repair is challenging in the body, but as technology continues to advance, hopefully we will have more in the future.
