Study Description

Brief Summary

1703: The study is designed as a randomized, phase III, multicenter trial comparing two acute graft-versus-host disease (aGVHD) prophylaxis regimens: tacrolimus/methotrexate (Tac/MTX) versus post-transplant cyclophosphamide/tacrolimus/mycophenolate mofetil (PTCy/Tac/MMF) in the setting of reduced intensity conditioning (RIC) allogeneic peripheral blood stem cell (PBSC) transplantation.

1801: The goal of this protocol is to test the primary hypothesis that the engraftment stool microbiome diversity predicts one-year non-relapse mortality in patients undergoing reduced intensity allogeneic HCT.

Detailed Description

1703: Graft-versus-Host Disease (GVHD) is a complication that affects many hematopoietic stem cell transplant (HSCT) patients; it occurs when the new cells from a transplant attack the recipient's body. The current standard GVHD prophylaxis regimen for patients with hematologic malignancies undergoing HSCT involves a combination of immunosuppressive agents given for the first 6 months after transplant.

The standard strategy of Tacrolimus/Methotrexate will be used as a control arm in comparison to one other treatment plan utilizing Tacrolimus/Mycophenolate Mofetil/Post-Transplant Cyclophosphamide. Study participants will receive an infusion of mobilized peripheral blood stem cell grafts on both arms. Study participants will be randomized to one of these two treatment arms.

1801: A relationship between the intestinal microbiota and graft-versus-host disease (GVHD) has long been appreciated but is still not well understood. Mice transplanted in germ-free conditions or treated with gut-decontaminating antibiotics developed less severe GVHD. Clinical studies initially suggested a benefit from near-total bacterial decontamination, but later showed no clear benefit and this approach was discontinued in the early 1990s. Partial gut decontamination continues to be practiced at many centers. More recently, the advent of next-generation sequencing (NGS) has resulted in cheaper and easier characterization of complex microbial mixtures. This has led to a renewed interest in evaluating the relationship between the microbiota and human health and disease, including recipients of hematopoietic cell transplantation (HCT). Similarly, NGS has also contributed to significant advancements in the investigator's understanding of immune reconstitution in HCT patients and how this may impact clinica outcomes.

The goal of this protocol is to test the primary hypothesis that the engraftment stool microbiome diversity predicts one-year non-relapse mortality in patients undergoing reduced intensity allogeneic HCT.

Active Comparator: Tacrolimus/Methotrexate Mobilized Peripheral Blood Stem Cell graft with Tacrolimus/Methotrexate	Procedure: Mobilized Peripheral Blood Stem Cell graft with Tacrolimus/Methotrexate Mobilized PBSC grafts will be administered on Day 0 to all patients according to individual institutional guidelines after appropriate processing and quantification has been performed by the local laboratory. Stem cells are administered through an indwelling central venous catheter. If infusion occurs over two days, Day 0 is the first day the infusion is initiated. Other Names: HSCT Drug: Tacrolimus Tacrolimus will be given per institutional practices, orally at a dose of 0.05-0.06 mg/kg/day or intravenously at a dose of 0.02-0.03 mg/kg/day starting on Day -3. The dose of tacrolimus may be rounded to the nearest 0.5 mg for oral formulations. Subsequent dosing will be based on blood levels per institutional guidelines with a suggested range of 5-15. If patients are on medications which alter the metabolism of tacrolimus (e.g.concurrent CYP3A4 inhibitors), the initial starting dose and subsequent doses should be altered as per institutional practices. Tacrolimus taper can be initiated at a minimum of 90 days post HCT if there is no evidence of active GVHD. The rate of tapering will be done according institutional practices and patients should be off tacrolimus by Day 180 post HCT if there is no evidence of active GVHD.

Outcome Measures

Primary Outcome Measures

GVHD-free, Relapse-free survival (GRFS) probability [1 year]
The primary endpoint is GRFS as a time to event endpoint from the time of randomization. All transplanted patients will be followed for the primary endpoint for one year; however the primary endpoint will be analyzed as a time to event endpoint. The primary analysis will be done using the intent-to-treat principle.

Secondary Outcome Measures

Acute GVHD [Days 100, 180, and 1 year]
Incidence of acute GVHD grade II-IV and grade III-IV at Days 100, 180 and 1 year will be estimated with 95% confidence intervals for each treatment group - using the cumulative incidence estimate, treating death prior to aGVHD as a competing event.
Chronic GVHD [1 year]
Incidence of chronic GVHD at 1 year will be estimated with 95% confidence intervals for each treatment group using the cumulative incidence estimate, treating death prior to chronic GVHD as a competing event.
Immunosuppression-free Survival [1 year]
Proportions of patients alive, relapse free, and off immune suppression at 1 year will be described for each treatment group, along with 95% confidence intervals.
Hematologic Recovery [Days 28 and 100]
Probabilities of neutrophil recovery by Day 28 and Day 100 will be described with 95% confidence intervals for each treatment group using the cumulative incidence estimate, treating death as a competing event.
Donor Cell Engraftment [Days 28 and 100]
Donor chimerism at Day 28 and Day 100 after transplantation in each of the randomized treatment arms will be described numerically as median and range for those evaluable as well as according to proportions with full (>95% donor cell), mixed (5.0-94.9% donor cells), graft rejection (<5%), or death prior to assessment of donor chimerism.
Disease Relapse or Progression [1 year]
Incidence of disease relapse or progression at 1 year will be estimated with 95% confidence intervals for each treatment group using the cumulative incidence estimate, treating death prior to disease relapse as a competing event.
Transplant-related Mortality [Days 100, 180 and 1 year]
Incidence of transplant-related mortality (TRM) at Days 100, 180 and 1 year will be estimated for each treatment group using the cumulative incidence estimate, treating disease relapse or progression as a competing event.
Toxicity grade over time [1 year]
All Grade 3-5 toxicities will be tabulated by grade for each randomized treatment arm, by type of toxicity as well as the peak grade overall. Toxicity frequencies up to 1 year will be described for each time interval as well as cumulative over time.
Infections [1 year]
The number of infections and the number of patients experiencing infections will be tabulated for each randomized treatment arm by type of infection, severity, and time period after transplant.
Disease-free Survival [1 year]
Kaplan-Meier curves will be constructed to estimate 1 year disease free survival probabilities for each treatment group.
Overall Survival [1 year]
Kaplan-Meier curves will be constructed to estimate 1 year overall survival probabilities for each treatment group.
Post-Transplant Lymphoproliferative Disease (PTLD) [1 year]
Probabilities of PTLD at 1-year post transplant will be described with 95% confidence intervals for each treatment group using the cumulative incidence estimate, treating death as a competing event.
Patient-Reported Outcomes (PRO) [Days 100, 180 and 1 year]
Patient-Reported Outcomes will be measured at baseline then at Days 100, 180 and one year post HCT. Using a repeated measures model, we will compute PRO composite scores and compare treatments after adjustment for baseline characteristics as described for the primary endpoint.
Diversity of Immune Repertoire [3, 6, 12, and 24 Months]
To study the diversity of the immune repertoire post-transplant and correlate with clinical outcomes, as well as study the impact on immune recovery of the method of GVHD prophylaxis and other patient and transplant factors.
Diversity and Composition of the Gut Microbiome [3, 6, 12, and 24 Months]
To study the diversity and composition of the gut microbiome post-transplant and correlate with clinical outcomes, as well as study the impact on the microbiome of the method of GVHD prophylaxis and other patient and transplant factors.
