Their IR department is really off IMO...first they never put out a PR to announce PDD was completed, but they did put out a PR for Rett completion.
Second, they never put out a PR saying they were going to present at CTAD....not that wouldve lifted the share price much if at all but still, give people a notice.
As for Rett, I hope it is your choice #3....the preliminary data looked like a home run on 6 patients and there are only 21 total patients.
