Summit are doing an IPO on Nasdaq next week. As part of that they have a detailed presentation which includes an excellent explanation on DMD and how their drug works. If your unaware of Utrophin upregulation it's well worth a watch.
Summit now listed on Nasdaq. (SMMT) Raised a further $34m to advance C1100 utrophin drug for DMD through phase 1b and into two phase 2's and fund next generation utrophin modulators coming out of Oxford University (which have a 20x better absorption profile). Prof Kay Davis's work.
Did anyone watch the presentation posted as it gives a very good idea as to why they think Utrophin will work for all DMD boys.
