Abstract
Acute and chronic steroid-refractory graft-versus-host disease (srGVHD) is a life-threatening complication of allogeneic stem cell transplantation. There are a number of reports on case series describing efficacy of ruxolitinib in both acute and chronic srGVHD. We conducted a prospective study (NCT02997280) in 75 patients with srGVHD (32 acute, 43 chronic, 41 adults, and 34 children). Patients with chronic GVHD had severe disease in 83% of cases, and acute GVHD patients had grade III-IV disease in 66% of cases. The overall response rate (ORR) was 75% (95% CI 57-89%) in acute GVHD and 81% (95% CI 67-92%) in chronic. Overall survival was 59% (95% CI 49-74%) in acute group and 85% (95% CI 70-93%). The major risk factors for lower survival were grade III-IV gastrointestinal involvement (29% vs 93%, p = 0.0001) in acute form and high disease risk score in chronic (65% vs 90%, p = 0.038). Toxicity was predominantly hematologic with 79% and 44% of grade III-IV neutropenia in acute and chronic groups, respectively. There was no difference between adults and children in terms of ORR (p = 0.31, p = 0.35), survival (p = 0.44, p = 0.12) and toxicity (p > 0.93). The study demonstrated that ruxolitinib is an effective option in acute and chronic srGVHD and can be used both in adults and children.

Intervention
Ruxolitinib at a starting dose of 10 mg bid for adults and children with weight >40 kg and 0.15 mg/kg bid for children with a weight less than 40 kg.
Comparison
None
Outcome
The overall response rate (ORR) was 75% in acute GVHD and 81% in chronic. Overall survival was 59% in acute group and 85% in chronic. The major risk factors for lower survival were grade III-IV gastrointestinal involvement (29% vs 93%) in acute form and high disease risk score in chronic (65% vs 90%). Toxicity was predominantly hematologic with 79% and 44% of grade III-IV neutropenia in acute and chronic groups, respectively. There was no difference between adults and children in terms of ORR, survival, and toxicity.

Abstract
The predictive value of graft composition and plasma biomarkers on the outcome of allogeneic HSCT is well known for conventional GVHD prophylaxis based on calcineurin inhibitors with or without antithymocyte globulin. Currently, there is limited data whether these results could be translated to post transplantation cyclophosphamide (PTCy). The prospective extension cohort of NCT02294552 trial enrolled 79 adult patients with acute leukemia in CR. Twenty-six received matched-related bone marrow (BM) grafts with single-agent PTCy and 53 received unrelated peripheral blood stem cell graft (PBSC) with PTCy, tacrolimus, and MMF. The grafts were studied by the flow cytometry, and plasma samples were analyzed by ELISA. In the cluster and major component analysis, we determined that transplantation from donors with high content of CD3, NKT, and CD16-CD56 + subpopulations in the PBSC grafts was associated with poor immunological recovery and compromised event-free survival (50% vs. 80%, HR 2.93, p = 0.015) both due to increased relapse incidence and non-relapse mortality. The significant independent predictor of moderate and severe chronic GVHD was the high prevalence of and iNKT, Vbeta11, and double-positive cells in the PBSC grafts from young donors (HR 2.75, p = 0.0483). No patterns could be identified for BM grafts and for plasma biomarkers.

Abstract
Large number of studies was published about predictive value of cytokines for graft-versus-host disease (GVHD) after allogeneic stem cell transplantation. Recently, there has been a growing interest in GVHD prophylaxis with post-transplant cyclophosphamide (PTCy). Clinical data on the dynamics of proinflammatory cytokines with this prophylaxis is lacking. In this study, we have measured the levels of IL-17, IL-6, IL-8, IFN-gamma and TNF-alpha in plasma on days -7, 0, +7, +14 and after engraftment in 20 patients with acute GVHD and 40 matched control patients with PTCy-based prophylaxis. Low levels of IL-8 (p=0.04) on day +7 and IFN-gamma (p=0.03) after engraftment were associated with grade II-IV acute GVHD. The same pattern was observed for severe acute GVHD. Low IFN-gamma after engraftment was also associated with increased non-relapse mortality (p=0.014). No impact of cytokine levels on overall survival and relapse incidence was observed (p>0.05). In conclusion, the dynamics of IL-8 and IFN-gamma in GVHD patients after PTCy was different from previously reported after conventional prophylaxis. Copyright © 2017 Elsevier Ltd.

Abstract
A number of studies were published with contradictory results comparing tacrolimus (Tac) and cyclosporine A (CsA) for graft-versus-host disease (GVHD) prophylaxis, but there are only few that accounted for pharmacokinetic (PK) parameters. In this study, we created a model based on median concentrations, variability of concentrations, and failures to maintain target levels that distinguished patients with low, intermediate, and high risks of acute GVHD (hazard ratios (HR) 1.77, 95%CI 1.36-2.32, p < 0.0001). This model was used to compare 95 patients with CsA and 239 with Tac GVHD prophylaxis. In the multivariate analysis, incorporating PK risk, no differences were observed for grade II-IV acute GVHD (HR 0.73, 95%CI 0.48-1.10, p = 0.13), but grade III-IV acute GVHD was lower in the Tac group (HR 0.47, 95%CI 0.28-0.78, p = 0.004). The observed difference was due to patients with high PK risk (HR 0.377, 95%CI 0.19-0.75, p = 0.005), but not with low and intermediate PK risk (p > 0.05). Patients in the Tac group had better GVHD relapse-free survival (HR = 0.659, p = 0.01) and comparable overall survival (p > 0.05). In conclusion, PK risk should be accounted for in comparisons of GVHD prophylaxis regimens with calcineurin inhibitors, and Tac was superior to CsA in patients with high, but not intermediate and low PK risk.
