Itacitinib for the Prevention of Graft Versus Host Disease in Patients Undergoing Donor Stem Cell Transplantation
Study Details
Study Description
Brief Summary
This phase II trial studies how well itacitinib works in preventing graft versus host disease in patients with blood disorders undergoing donor stem cell transplantation. A donor transplantation uses blood-making cells from a family member or unrelated donor to remove and replace abnormal blood cells. Graft versus host disease is a reaction of the donor's immune cells against the patient's body. Itacitinib plus standard treatment may help prevent graft versus host disease in patients who have received a donor stem cell transplantation.

Detailed Description
PRIMARY OBJECTIVE:
- To estimate the graft-versus (vs.) host disease-free/relapse free survival (GRFS) rate of itacitinib used as prophylaxis to prevent graft versus host disease (GVHD) after allogeneic stem cell transplantation (ASCT) at one year.
SECONDARY OBJECTIVES:
-
To assess the time to neutrophil and platelet engraftment and compare between matched and unmatched donors.
-
To assess safety of itacitinib as measured by non-relapse mortality (NRM) at day 100.
-
To assess the toxicity profile associated with this regimen. IV. To assess the incidence of acute and chronic GVHD. V. To assess the incidence of disease relapse. VI. To assess the incidence of non-relapse mortality. VII. To assess overall survival and progression-free survival. VIII. To assess the incidence of withdrawal syndrome in patients with myelofibrosis.
TERTIARY OBJECTIVES (CORRELATIVE STUDIES):
-
To study immune recovery and cytokines at various time points pre and post-transplant.
-
To study deoxyribonucleic acid (DNA) damage studies in various cells post-transplant.
OUTLINE:
CONDITIONING CHEMOTHERAPY: Patients receive busulfan intravenously (IV) over 3 hours on days -20, -13, and -6 to -3, and fludarabine IV over 1 hour on days -6 to -3 in the absence of disease progression or unacceptable toxicity.
ALLOGENEIC STEM CELL TRANSPLANTATION: Patients undergo ASCT on day 0.
GVHD PROPHYLAXIS: Patients receive itacitinib orally (PO) once daily (QD) on days -21 to 80. Patients with no evidence of GVHD at day 80 receive a tapered dose of itacitinib until day 90. Patients also receive tacrolimus IV then PO twice daily (BID) for 3 months when able, and methotrexate IV over 30 minutes on days 1, 3, and 6 (day 11 also for patients with a matched unrelated donor).
After completion of study treatment, patients are followed up at 100 days, 6 months, and 1 year.

Outcome Measures
Primary Outcome Measures
- Graft versus host disease (GVHD)-free/relapse free survival rate [At 1 year]
The proportion of patients who are alive without disease relapse of GVHD at one year will be reported, along with the corresponding 95% confidence interval. Logistic regression will be used to assess the association between success and clinical and treatment covariates of interest.
Secondary Outcome Measures
- Time to neutrophil engraftment [Up to day 42]
Will be calculated from the time of transplant and estimated by the Kaplan-Meier method. Distributions will be compared between patients with matched and mismatched donors via the long-rank test.
- Time to platelet engraftment [Up to day 42]
Will be calculated from the time of transplant and estimated by the Kaplan-Meier method. Distributions will be compared between patients with matched and mismatched donors via the long-rank test.
- To assess the incidence of non-relapse mortality [At day 100]
- To assess the toxicity profile associated with this regimen [Up to 1 year]
- To assess the incidence of acute and chronic GVHD. [Up to 1 year]
- Time to disease relapse [Up to 1 year]
Will be modeled using Cox proportional hazards regression models, considering clinical, demographic, and treatment covariates of interest.
- Incidence of non-relapse mortality [Up to 1 year]
Will be modeled using Cox proportional hazards regression models, considering clinical, demographic, and treatment covariates of interest. Will be assessed in a competing risks framework, with similar analyses performed.
- To assess overall survival and progression-free survival. [From day of transplant until day of death, assessed up to 1 year]
- Incidence of withdrawal syndrome in patients with myelofibrosis [Up to 1 year]
Other Outcome Measures
- Immune recovery and cytokines [Up to 1 year]
Generalized linear mixed models will be used to assess the association between cytokines over time and treatment and other factors.
- Deoxyribonucleic acid (DNA) damage studies [Up to 1 year]
The proportion of patients with DNA damage will be reported, and generalized logistic mixed models may be used to assess the association with similar covariates.
