FLT-3 inhibitors such as sorafenib, crenolanib, midostaurin can also be given up to 3 days before conditioning regimen.)
* DONOR: The donor must be examined and have specific tests performed according to existing institutional guidelines to evaluate his/her candidacy as a donor including the following:
