that ProSavin was making claims of great efficacy and that there was a lot of optimistic "noise" surrounding the product. I wasn't comparing the two products.

1990nyboy, great summary, ProSavin is behind other gene therapies in terms of clinical trial progress. However its effects are claimed to be obvious within weeks and (as already mentioned), these effects are hoped to be substantial. As a result it appears to be more black and white than the others, it will either crash and burn spectacularly or be very exciting all within a matter of weeks.

On the other hand it may be hideously over hyped in order to gain investment

Fingers crossed,
Neil.

p.s. 1990, there is another trial, the old Avigen now genzyme product, AV201. Seems to be struggling to get interest though and may well have been dropped now that Genzyme are working with Ceregene.
