Some people on the Yahoo board are saying that the statement about "we are pleased with the results" just means that there are no side effects. Well, here is the exact statement (again):

We are very pleased with the results to date especially considering the lower doses to date.

So if that were true, that they were just happy to have no side effects, why would he say "ESPECIALLY CONSIDERING THE LOWER DOSES TO DATE"? If this were about side effects, the statement would not say that -- it would be talking about how they were happy at HIGH doses (to not have side effects).

Common sense, and command of the English language. Q.E.D.
