NCT05436418
Background: Blood cancers (such as leukemias or lymphomas) often do not respond to standard treatments. A transplant of blood stem cells from a healthy donor can help people with these cancers. Sometimes these transplants cause serious side effects, including a common immunologic problem called graft-versus-host disease. A drug called cyclophosphamide given early after the transplant (post-transplantation cyclophosphamide, PTCy) can reduce these complications. But sometimes this drug has its own negative effects. Furthermore, studies in mice suggest that an intermediate, rather than very high, dose of this drug may best protect against graft-versus-host disease. Objective: To find out if a lower dose of PTCy is more helpful for people who undergo blood stem cell transplants. Eligibility: People aged 18 and older who have a blood cancer and are eligible for a transplant of blood stem cells from another person. Healthy donors are also needed but must be related to the individual needing the transplant. Design: Participants will undergo screening. Transplant recipients will have imaging scans and tests of their heart and lung function. They will be assessed for the status of their cancer, including bone marrow taken from their pelvis and possibly also scans and/or fluid drawn from the spine depending on the disease type. Donors will be screened for general health. They will give several tubes of blood. They will give an oral swab and saliva and stool samples for research. Recipients will be in the hospital at least 4 to 6 weeks. They will have a temporary catheter inserted into a vein in the chest or neck. Medications will be given and blood will be drawn through the catheter. The transplanted stem cells will be given through the catheter. Participants will receive medications both before and after the transplant. Participants will return to the clinic at least once a week for 3 months after leaving the hospital. Follow-up visits will continue periodically for 5 years.

NCT03993639
Data collection to evaluate safety and effect of hematopoietic stem cell mobilization into the peripheral blood after a single subcutaneous (SC) dose of KRN125(Pegfilgrastim)in healthy adults.
NCT04582604
The purpose of this study is to determine the efficacy and safety of Ruxolitinib and Decitabine intensified Conditioning Regimen in Patients with High Risk hematological malignancies undergoing allogeneic peripheral blood stem cell transplantation.
NCT02848105
aGVHD remains as complication in patients after allogeneic stem cell transplantation. Methylprednisolone at 1\~2mg/kg is considered as standard first-line treatment. In recent lab study, we demonstrated that valproic acid (VPA) as histone deacetylase inhibitor can inhibit CD4+ Th1 and Th17 cells and control the aGVDH in mice model while preserve the GVL effects. In this study, we tested the hypothesis that adding VPA to standard dose steroid treatment may improve the outcome of aGVHD.
