I haven't seen any results yet, however, the next update, which is due now, will be a guide as to whether they are on track or with a bit of luck ahead in the recruitment and treatment of the cohorts.
If the first was treated last December, I would expect them to be partially or fully 'cured' by now. Whether they will update on the actual treatment results as they progress I dont know, but it would likely send a rocket up the SP.
