Here's my take on this letter:
"Bob, We know that the DSMB(Data Safety Monitoring Board) and the CRO are very busy crunching the data...from the standpoint of Cortex, we need to now wait until we can see results which are sufficiently complete ....The first study to be completed and analyzed will be the Parexel dose ranging study. Roger"
For whatever reason, we're going to have to wait. The company seems to intend to release the study results as they get them, rather than simultaneously. I have no experience in clinical trials, so I don't know how time-consuming the data-analysis might be. There is no advantage for them to sit on bad news if that's what they have. At least there's no press release friday evening. In fairness, this is around the very earliest we could be getting results, so the fact that we haven't heard anything yet is probably meaningless.
I'm worried sick though.
