No inventions not already included in the original disclosures of a patent can later be part of amended claims. In other words unless MS was part of the descriptive text of the invention (or perhaps already in dependent claims), one would have to file a new patent application possibly as continuation part. PS! I have not checked if the patent in question includes any disclosures around the use of the compound in MS.
