Brief Summary

The study will be conducted in two phases. The phase I portion will employ a 3+3 dose-escalation design to define the maximum tolerated dose (MTD) of abatacept added to PTCy and bortezomib following HSCT. The phase II portion will consist of two single-arm, open-label, optimal 2-stage Simon design studies conducted in two separate strata for HLA-matched and HLA-mismatched donor transplants.
