Hard say how slow or quick enrollment will be, but we know that Missling said readout in PPD could be 2019 for PDD.
Let's say instead that readout is mid 2020 or roughly that the whole trial from start to finish is 2 years in total. The last patient would then have to be enrolled 12 weeks + data processing time before mid 2020, so say Dec 2019.
Not sure we can do better than that sort of guestimate.
If I remember correct from my discussion with the IR person, when a patient is enrolled, he/she starts to receive the dosage. Hope I am correct - would not want to misquote..
