Phase 2Active Not RecruitingNCT04859946

M.D. Anderson Cancer Center31 enrolled

Overview

This phase II trial studies if itacitinib plus standard of care treatment may help prevent graft-versus-host-disease (GVHD) in patients who have received an allogeneic (donor) stem cell transplant. An allogeneic transplant uses blood-making cells from a family member or unrelated donor to remove and replace a patient's abnormal blood cells. Sometimes the transplanted cells from a donor can attack the body's normal cells (called graft-versus-host disease). Giving itacitinib with standard of care treatment after the transplant may stop this from happening.

PRIMARY OBJECTIVE: I. To compare the 100-day acute grade 2-4 GvHD rate to matched controls. SECONDARY OBJECTIVES: I. To compare the 1-year rate of GvHD-free, relapse-free survival to matched controls. II. To assess the time to neutrophil and platelet engraftment. III. To assess the toxicity profile associated with this regimen. IV. To assess the incidence of severe grade 3-4 acute GVHD. V. To assess the incidence of limited, extensive, and moderate to severe chronic GVHD. VI. To assess the incidence of disease relapse. VII. To assess the incidence of non-relapse mortality. VIII. To assess overall survival and progression-free survival. IX. To assess immunosuppression discontinuation rate. TERTIARY OBJECTIVE (CORRELATIVE STUDY): I. Immune recovery and cytokines at various time points pre- and post- transplant OUTLINE: CONDITIONING: Patients receive busulfan intravenously (IV) over 3 hours on days -20, -13, and -6 to -3, thiotepa IV on day -7, and fludarabine IV over 1 hour on days -6 to -3. STEM CELL TRANSPLANT: Patients undergo stem cell transplant on day 0. GVHD PROPHYLAXIS: Patients receive cyclophosphamide IV over 3 hours on days 3 and 4. Patients also receive itacitinib orally (PO) once daily (QD) on days 5-60 in the absence of disease progression or unacceptable toxicity. Beginning day 5 after stem cell transplant, patients also receive tacrolimus IV over 24 hours until able to tolerate oral tacrolimus, whereby patients then receive tacrolimus PO twice daily (BID). After completion of study intervention, patients are followed up at days 100, 180, and 365 after stem cell transplant.

Outcomes

Primary Outcomes

Incidence of acute grade 2-4 graft versus host disease (GVHD)

The 100-day acute grade 2-4 GvHD rate will be compared between groups using Fisher's exact test. Matched logistic regression techniques will also be considered for this endpoint. The proportion of patients with acute grade 2-4 GVHD at 100 days will be reported, along with the corresponding 95% confidence interval.

Time frame: At 100 days after stem cell transplant

Secondary Outcomes

GVHD-free relapse-free survival

Will be compared between groups using the log-rank test. The method of Kaplan and Meier will be used to estimate the distribution of GVHD-free, relapse-free survival. The estimated probability will be reported at 1 year along with a corresponding 95% confidence interval. In addition, Cox proportional hazards regression models will be fit to this endpoint, considering clinical, demographic, and treatment covariates of interest.

Time frame: From day of stem cell transplant to time of grade 3 or 4 acute GVHD or chronic GVHD needing systemic immunosuppression or relapse or death whichever occurs first, assessed at 1 year after stem cell transplant

Time to neutrophil and platelet engraftment

Engraftment is defined as the presence of neutrophil recovery by day 28 post stem cell infusion. Neutrophil recovery is defined as a sustained absolute neutrophil count (ANC) \> 0.5 x 10\^9/L for three consecutive days. Initial platelet recovery is defined as the first date of three consecutive laboratory values obtained for platelet count was \>= 20 x 10\^9/L AND no platelet transfusions were administered for seven consecutive days immediately preceding this date. 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 log-rank test.

Time frame: Up to 365 days after stem cell transplant

Overall survival

Will be calculated from the time of transplant by the method of Kaplan and Meier. Cox proportional hazards regression analysis will be used to assess the association between these survival parameters and clinical and treatment covariates of interest.
