'The company is also funding the development of new technologies that could help to treat brain cancer and eye disorders. Of more interest is perhaps its development of a radioprotector, which makes healthy skin less sensitive to radiation. This has the potential to reduce side effects for many different cancer therapies, and may eventually allow for expanded use of SIR-Spheres specifically.'

Not sure about the radioprotector, and brain cancer & eye disorders. Could be interesting, for the longer term.
