I am also surprised for lack of focus on gvhd - 10 patients is small population - they could just open 2 site and continue enrollment and keep costs down. Running parallel tasks is very important.
As we have seen HIV is a long term activity - even if they complete BLA filing in Mar - we still have 6-8 months for approval.
On other hand gvhd patients can start showing results 4 months after 1st patients - being open label they can issue positive results and get more coverage
Well - hope they know what they are doing and in the end we as investors make money
