One last meeting listed on the H1 2015 agenda for Resverlogix:

15th European Meeting on Complement in Human Disease, Uppsala, Sweden, June 27-30.

I've never heard RVX comment on the complement system. And frankly, I know very little about it and had to consult Wikipedia.

Perhaps this is related to the mysterious Orphan Indication that RVX has allude to another trial being designed around?
