Correct, LooseLips, the problem with finding patients for the Bril-OM study is that they need to be people who have not already had a bunch of treatment, since previous radiation and chemo may affect whether or not they'll get oral mucositis, and if they do, what the severity is and how well the tissues can recover.

That's why I inquired about Canadian patients being admitted to the study, too -- Buffalo area is a great location for a study like this. It should draw from a relatively large population that is NOT in an urban area and so is less likely to be treated. Plus if they are allowed to enroll Canadians, that's another large non-urban area to draw patients from. People in large urban areas are more likely to have been diagnosed earlier and gotten chemo/radiation, than people in more rural environs.

I don't know that we can really draw any conclusions because, as you say, it could either be that they just need more patients in the study, or, it could be that the study is going well and they want to get more patients in faster so they can conclude sooner. The one scenario I DON'T see as possible is that the study is not going well. I don't think they'd want to spend company money on the expense of setting up a new site if the study were not at least promising.
In fact, they'd want to NOT set up a new site if it weren't going well, because why rush to have bad news? So I think this is positive news in the long run.
