You're probably right that we won't get data from any other trial before the AD readout this summer.
I suppose a partnership in another indication (MS?) is possible, but certainly can't predict if/when that will happen. I guess the only solid, concrete milestone is, as you point out, that the board is secretly voting on a buyout this week, lol.
Looking forward to the clean data readout in AD, and whatever else the company puts out on startup of other trials.
