Toinv - "The reason I mentioned San Francisco is that was listed in clinicaltrials.gov under location when I did the search. I think that is because Mike Sweeney is SF based but I don't know if that is the reason."

If I remember correctly, someone asked IR about this and they stated that since Mike Sweeney is the lead and is in SF, that is why it is listed that way on clinicaltrials.gov.
