Brief summary

The purpose of this study is to assess the impact and safety of itacitinib in combination with calcineurin inhibitor (CNI)-based interventions for the prophylaxis of graft-versus-host-disease (GVHD).

Interventions

DRUGItacitinib

Itacitinib administered orally once daily at the protocol-defined dose.

The CNI-based prophylaxis regimen will be identified by the investigator before the subject's enrollment and will consist of the combination of tacrolimus/methotrexate, cyclosporine A/mycophenolate mofetil or tacrolimus plus post-treatment cyclophosphamide. Antithymocyte globulin may be included at the treating investigator's discretion with the tacrolimus/methotrexate or cyclosporine A/mycophenolate mofetil combinations.

Inclusion criteria

* Subjects with acute leukemia, chronic myelogenous leukemia, or myelodysplasia with no circulating blasts and \< 5% blasts in the bone marrow. * Subjects with non-Hodgkin lymphoma, including but not limited to chronic lymphocytic leukemia/small lymphocytic lymphoma, follicular, marginal zone, diffuse large B cell, or mantle cell lymphoma must have chemosensitive disease at time of transplant. Subjects with Hodgkin lymphoma with chemosensitive disease at the time of transplant. * Must be candidates for reduced-intensity conditioning regimens. * Must be candidates for peripheral blood stem cell transplants. * Karnofsky Performance Status score ≥ 70% or Eastern Cooperative Oncology Group Performance Status score of 0 to 2. * Serum creatinine ≤ 2.0 mg/dL or creatinine clearance ≥ 40 mL/min measured or calculated by Cockcroft-Gault equation. * Be willing to avoid pregnancy or fathering children.

Exclusion criteria

* Has previously received an allogenic hematopoietic stem cell transplant. * Presence of an active uncontrolled infection. * Known HIV infection. * Active hepatitis B virus (HBV) or hepatitis C virus (HCV) infection that requires treatment or at risk for HBV reactivation. * Prior malignancies. * Severe organ dysfunction. * Prior treatment with a JAK inhibitor or with an investigational agent, device, or procedure within 21 days of enrollment. * Currently breastfeeding. * Known allergies, hypersensitivity, or intolerance to any of the study medications. * Receipt of live (including attenuated) vaccines during the study, or anticipation of need for such a vaccine during the study. * History of primary idiopathic myelofibrosis or any severe marrow fibrosis that would prolong neutrophil engraftment to \> 28 days after transplant. * Post-transplant maintenance therapy for the hematologic malignancy or plans to initiate maintenance therapy during study treatment.

Design outcomes

Primary

MeasureTime frameDescription
Proportion of participants with hematologic recovery when itacitinib is added to GVHD prophylaxis treatmentDay 28Hematologic recovery defined as demonstrating both neutrophil recovery (ANC ≥ 500/mm\^3 for 3 consecutive measurements) and platelet recovery (platelet count ≥ 20,000/mm\^3 with no requirement for platelet transfusion in the preceding 3 days).

Secondary

MeasureTime frameDescription
Relapse-free survivalUp to 1 yearDefined as the interval between enrollment and malignancy relapse or progression, or death, whichever occurs first.
Transplant-related mortalityUp to 1 yearDefined as the proportion of subjects who die due to causes other than malignancy relapse or progression.
Median time to neutrophil and platelet engraftmentUp to Day 28Defined as the median time to achieve neutrophil and platelet engraftment.
Percentage of participants who achieve neutrophil and platelet engraftmentUp to Day 28Defined as the median time to achieve engraftment and hematologic recovery at prespecified time points.
Donor ChimerismUp to Day 28
GVHD relapse-free survival rateDays 100, 180 and 365Defined as the proportion of subjects who do not experience Grade III-IV acute GVHD (aGVHD), chronic GVHD (cGVHD) requiring systemic therapy, malignancy relapse or progression, or death due to any cause.
Proportion of subjects who are diagnosed with cGVHD by grade (mild, moderate, or severe)Up to 1 yearMeasured to assess the incidence of cGVHD.
Infection rateUp to 1 yearDefined as the proportion of subjects who demonstrate an infection and/or cytomegalovirus reactivation.
Overall survivalUp to 1 yearDefined as the interval between enrollment and death due to any cause.
Participants with Grade 3-5 treatment-emergent adverse events (TEAEs)Up to approximately 200 daysTEAE is defined as either an adverse event (AE) reported for the first time or worsening of a pre-existing condition after the first dose of study treatment.
Proportion of subjects who are diagnosed with Grade II-IV aGVHD, by each grade and by Grade III/IVDays 100 and Days 180Measured to assess the incidence of aGVHD.
