ListOutcomeTime frameDescription
PrimaryGraft failure rate42 days after blood stem cell (PB) transplantation
Graft failure defined as having had a primary or secondary graft failure by 42 days after blood stem cell (PB) transplantation. Primary graft failure is defined as failure to achieve an absolute neutrophil count (ANC) of \>500/ μL by 42 days after blood stem cell (PB) transplantation or a total donor chimerism of \>5%. Secondary graft failure is defined as cytopenias after initial engraftment (ANC \<500/μL) and a total donor cell chimerism decreasing to less than 5%.
SecondaryEvent-free survival (EFS) RateDuration of study, up to 7 years
Event-free survival is defined as the time from treatment initiation to the occurrence of primary graft failure, death, Graft-versus-Host Disease (GVHD) Grade III-IV, whichever comes first. Patients without events will be censored at the time of last follow-up assessment.
SecondaryTime to engraftment of NeutrophilsUp to 7 yearsTime to neutrophil engraftment is defined as the first of 3 measurements on consecutive days when the patient has an absolute neutrophil count of 500/μL after conditioning.
SecondaryTime to engraftment of PlateletsUp to 7 years
Time to platelet engraftment will be defined as the first day of a minimum of 3 measurements on different days that the patient has achieved a platelet count \> 50,000/μL AND did not receive a platelet transfusion in the previous 7 days. The exception is the case in which a subject is given a platelet transfusion specifically to achieve a platelet threshold to allow an elective invasive procedure, such as a central catheter removal. Time from treatment initiation to successful donor cell engraftment defined as having achieved \> 50% total Peripheral Blood Mononuclear Cells (PMC) donor cell chimerism upon successful engraftment at day +30 or upon meeting ANC and Plt engraftment whatever occurs first.
SecondaryIncidence of Graft-versus-Host Disease (GVHD) of any gradeUp to 7 years
Incidence of acute and chronic GVHD of any grade as evaluated according to The Center for International Blood and Marrow Transplant Research (CIBMTR) and National Institutes of Health (NIH) criteria respectively.
SecondaryIncidence of other transplant related toxicities12 Months Post Stem Cell Transplant
Incidence of other transplant related toxicities, including Veno-occlusive disease (VOD), Idiopathic pneumonia syndrome (IPS), Central nervous system (CNS) toxicity, or Posterior reversible encephalopathy syndrome (PRES).
SecondaryIncidence of significant transplant-related infections12 Months Post Stem Cell Transplant
Significant infections will be recorded including but not limited to bacterial or fungal sepsis, cytomegalovirus (CMV) reactivation with/without clinical disease, adenovirus infection, Epstein-Barr virus (EBV) reactivation with or without post-transplant lymphoproliferative disorder (PTLD), other significant viral reactivations or community-acquired viral infections and invasive mold infections.
SecondaryNumber of participants with donor chimerism >5%100 days post-transplant and 1 year post transplant
Chimerism is a measure of the engraftment of donor cells within the recipient and is expressed as the percentage ratio between the number of donor cells and recipient cells. Chimerism will be determined by Short Tandem Repeat analysis.
SecondaryPercentage of Participants who Achieve Immune Reconstitution12 Months Post Stem Cell Transplant
Peripheral blood quantitative assessment of CD3+, CD4+, CD8+, CD19+, and CD16+/56+ lymphocytes will be assessed by flow cytometry. In addition, quantitative immunoglobulins will be measured for IgA, IgM and IgG. These will be performed at Day +60 (±10 days) as well as at 1 year (+/- 2 weeks) and after long term follow up at the discretion of the investigator. Descriptive statistics will be used to describe the percentage of patients who are able to achieve reconstitution of important lymphocyte subsets and B cell function at the defined timepoint above.
SecondaryFollicle-stimulating hormone (FSH) titerAt study inclusion and at 1 year post-transplantTo assess the impact of the conditioning on fertility, FSH titers will be measured.
SecondaryLuteinizing hormone (LH) titerAt study inclusion and at 1 year post-transplantTo assess the impact of the conditioning on fertility, LH titers will be measured.
SecondaryAnti-Müllerian Hormone (AMH) titerAt study inclusion and at 1 year post-transplantTo assess the impact of the conditioning on fertility, AMH titers will be measured
SecondaryTestosterone titerAt study inclusion and at 1 year post-transplantTo assess the impact of the conditioning on fertility, testosterone titers will be measured.
SecondarySperm titerAt study inclusion and at 1 year post-transplantTo assess the impact of the conditioning on fertility, sperm titers will be measured.
