I'd say that was a pretty accurate picture of the position pixie. When no one knows anything (as in a double blind trial) then there's nothing to go on. Except that, as many have observed, we know that the longer the trial runs, the greater the certainty that there are no significant adverse side effects.

I had expected the price to rise slowly after that last announcement as folks got set even if some of them planned to unload before the results of the trial became available much as bsb traders do in oil stocks. This doesn't seem to have happened to any great extent.
