Overview

This phase II trial tests how well ruxolitinib as a maintenance medication works to prevent relapse and graft-versus-host disease (GVHD) for patients who have undergone stem cell transplantation for T-cell lymphoma. GVHD is a common problem that may occur after a blood stem cell transplant. The "graft" is the donor blood cells that patients get during the transplant. The "host" is the person receiving the cells. GVHD is when the donor graft attacks and damages some of the transplant recipient's tissues. Ruxolitinib is a type of drug called a Janus kinase (JAK) inhibitor which works by decreasing the immune response of cells in the body. It is also a cancer growth blocker that blocks the growth factors that trigger the cancer cells to divide and grow. Ruxolitinib works by blocking a gene, called JAK2, that is important in the production of cancer cells.

PRIMARY OBJECTIVES: I. Determine the effect of ruxolitinib phosphate (ruxolitinib) on relapse at 1-year after autologous (auto) stem cell transplant (SCT) in T-cell lymphoma (TCL). II. Determine the effect of ruxolitinib on graft versus host disease (GvHD) and relapse free-survival (GRFS) at 1-year for allogeneic (allo) SCT in TCL. SECONDARY OBJECTIVES: PRIMARY OBJECTIVES: I. Determine the effect of ruxolitinib phosphate (ruxolitinib) on relapse at 1-year after autologous (auto) stem cell transplant (SCT) in T-cell lymphoma (TCL). II. Determine the effect of ruxolitinib on graft versus host disease (GvHD) and relapse free-survival (GRFS) at 1-year for allogeneic (allo) SCT in TCL. SECONDARY OBJECTIVES: I. Survival (progression free survival \[PFS\]/overall survival \[OS\]) of patients with ruxolitinib maintenance (auto-SCT, allo-SCT, whole cohort). II. Determine the safety and feasibility of ruxolitinib maintenance post-SCT. III. Determine the effect of ruxolitinib on the cumulative incidence (CI) of grade II-IV acute GVHD (alloSCT), chronic extensive GVHD, non-relapse mortality (NRM) (auto-SCT and allo-SCT). EXPLORATORY OBJECTIVES: I. Determine the effect of maintenance ruxolitinib compared to matched historical controls using the Center for International Blood and Marrow Transplant Research (CIBMTR) registry. II. Determine the effect of ruxolitinib on immune modulation and reconstitution post-allo-SCT and upon disease relapse. OUTLINE: Starting day +35 to day +120 post-SCT, patients receive ruxolitinib orally (PO) twice daily (BID) on days 1-30 of each cycle. Cycles repeat every 30 days for 1 year post-SCT, in the absence of disease progression or unacceptable toxicity. Patients undergo positron emission tomography (PET)-computed tomography (CT) scan and blood sample collection throughout the study. Patients may undergo bone marrow biopsy and/or tissue biopsy throughout the study, at time of progression. After completion of study treatment, patients are followed up at 18 and 24 months then yearly until 5 years and at progression.

Outcomes

Primary Outcomes

Cumulative Incidence (CI) of relapse

Relapse is defined as evidence of disease progression or recurrence based on Lugano criteria or confirmed by biopsy.

Time frame: at 1-year post-auto-SCT

GvHD and relapse free-survival (GRFS)

GRFS is a composite endpoint of survival without grade III-IV acute GVHD, systemic therapy-requiring chronic GVHD (cGVHD), relapse, or death. Will be evaluated using the Kaplan-Meier method, with median survival and probability of surviving to relevant time points reported with point estimates and 90% confidence intervals separately for each study cohort. Comparisons to Center for International Blood and Marrow Transplant Research (CIBMTR) patients will use log-rank tests.

Time frame: at 1-year post-allo-SCT

Secondary Outcomes

Progression-Free survival (PFS)

Will be evaluated using the Kaplan-Meier method, with median survival and probability of surviving to relevant time points reported with point estimates and 90% confidence intervals separately for each study cohort. Comparisons to CIBMTR patients will use log-rank tests

Time frame: At 1 and 2 years

Overall Survival (OS)

Time frame: At 1 and 2 years

Cumulative incidence of grade II-IV acute GVHD (allo-SCT cohort)

Will be conducted using non-relapse mortality (NRM) as a competing risk, with estimates of cumulative incidence at various time points reported with 90% confidence intervals. Cumulative incidences will be compared to CIBMTR data using Fine-Gray analysis.

Time frame: Up to 5 years

Cumulative incidence of chronic extensive GvHD (allo-SCT cohort)
