The goal of this clinical trial is to determine the effectiveness of Reduced Dose Post-Transplant Cyclophosphamide (PTCy) in patients with hematologic malignancies after receiving an HLA-Mismatched Unrelated Donor (MMUD) . The main question\[s\] it aims to answer are:

* Does a reduced dose of PTCy reduce the occurrence of infections in the first 100 days after transplant?
* Does a reduced dose of PTCy maintain the same level of protection against Graft Versus Host Disease (GvHD) as the standard dose of PTCy?

This is a prospective, multi-center, Phase II study of hematopoietic cell transplantation (HCT) using human leukocyte antigen (HLA)-mismatched unrelated donors (MMUD) for peripheral blood stem cell transplant in adults and bone marrow stem cell transplant in children. Post-transplant cyclophosphamide (PTCy), tacrolimus and mycophenolate mofetil (MMF) will be used for for graft versus host disease (GVHD) prophylaxis. This trial will study how well this treatment works in patients with hematologic malignancies.
