Abstract
We conducted a phase I-II study to evaluate Nilotinib (NIL) safety and pharmacokinetics in 22 SR-cGVHD patients; we also evaluated ORR by using in parallel NIH criteria and an exploratory approach, combining objective improvement (OI) without failure criteria (GITMO criteria). Results: 22 patients were enrolled. After dose escalation up to 600 mg/day, MTD was not reached. Main toxicities were asthenia, headache, nausea, pruritus, cramps, and mild anemia. Mean and median plasma concentrations of NIL (C-NIL) were 817 (SD +/- 450) and 773 ng/ml. ORR at 6 months, according to 2005 and 2014 NIH and GITMO criteria were 27.8%, 22.2%, and 55.6% respectively; close correspondence has been observed for ORR, according to 2014 NIH criteria, both assessed in a conventional way and assisted by dedicated software (CROSY). At 48 months OS was 75% while FFS, according to NIH and GITMO criteria, was 30 and 25%. In conclusion the safety profile of NIL and long-term outcome makes NIL an attractive option in SR-cGVHD. Exploratory GITMO criteria could represent an alternative tool for easy response evaluation in patients with prevalent skin and lung involvement, but require validation in a larger population; CROSY software showed excellent reliability in capturing ORR according to the 2014 NIH criteria.

Abstract
The effects of graft or donor characteristics in haploidentical hematopoietic cell transplantation (HCT) using post-transplant cyclophosphamide (PT-Cy) are largely unknown. In this multicenter retrospective study we analyzed the correlations between graft cell composition (CD34+, CD3+) and donor features on transplant outcomes in 234 patients who underwent HCT between 2010 and 2016. On multivariate analysis, the use of peripheral blood stem cells (PBSC) was associated with an increased incidence of grade 2-4 acute GVHD [HR 1.94, 95% confidence Interval (CI) = 1.01-3.98, p = 0.05]. An elevated CD3+ graft content was associated with an increased incidence of all-grade chronic GVHD [HR 1.36 (95% CI = 1.06-1.74), p = 0.01]. This effect was confirmed only for the PBSC graft group. A higher CD34+ graft content had a protective role on non-relapse mortality [HR 0.78 (95% CI = 0.62-0.96), p = 0.02] but this was confirmed only for the bone marrow (BM)-derived graft cohort. Donor characteristics did not influence any outcomes. GVHD prophylaxis should be modulated accordingly to CD3+ graft content, especially when a PBSC graft is used. These results need further validation in prospective trials.

Abstract
Acute graft-versus-host disease (aGVHD) results in significant morbidity and mortality after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Noninvasive diagnostic and prognostic tests for aGVHD are currently lacking, but would be beneficial in predicting aGVHD and improving the safety of allo-HSCT. Circulating microRNAs exhibit marked stability and may serve as biomarkers in several clinical settings. Here, we evaluated the use of circulating microRNAs as predictive biomarkers of aGVHD in lymphoma patients after allo-HSCT from matched unrelated donors (MUDs). After receiving informed consent, we prospectively collected plasma samples from 24 lymphoma patients before and after unmanipulated MUD allo-HSCT; microRNAs were then isolated. Fourteen patients developed aGVHD symptoms at a median of 48 days (range: 32-90) post-transplantation. Two patients developed intestinal GVHD, eight cutaneous GVHD, and four multiorgan GVHD. The microRNA expression profile was examined using quantitative real-time polymerase chain reaction (qRT-PCR). MicroRNAs 194 and 518f were significantly upregulated in aGVHD samples compared with samples taken from non-aGVHD patients. Remarkably, these upregulated microRNAs could be detected before the onset of aGVHD. Pathway prediction analysis indicated that these microRNAs may regulate critical pathways involved in aGVHD pathogenesis. Considering the noninvasive characteristics of plasma sampling and the feasibility of detecting miRNAs after allo-HSCT using real-time polymerase chain reaction, our results indicate that circulating microRNAs have the potential to enable an earlier aGVHD diagnosis and might assist in individualizing therapeutic strategies after MUD allo-HSCT. Nevertheless, standardization of blood sampling and analysis protocols is mandatory for the introduction of miRNA profiling into routine clinical use.

Abstract
BACKGROUND Extracorporeal photopheresis (ECP) is considered a valid second-line treatment for acute and chronic graft versus host disease (GVHD). METHODS Ninety-four patients with acute GVHD (aGVHD) (n = 45) and chronic GVHD (cGVHD) (n = 49), retrospectively recruited in 6 Italian centers, were submitted to ECP for second-line treatment. At the time of ECP, 22 (49%) and 23 (51%) of 45 patients with aGHVD were nonresponsive and in partial remission (PR) after steroids, respectively, and all the 49 patients with cGVHD were steroid refractory. RESULTS Forty-one (91%) of 45 patients with aGVHD achieved complete remission (CR) after ECP. Fifteen (33%) of 45 patients developed cGVHD. The CR rate in patients who started ECP being nonresponsive and in PR after steroid was 86% and 96%, respectively. After a median follow-up of 20 months (range, 2-72), 15 (33%) of 45 patients developed cGHVD and 16 (35%) of 45 patients died, in 3 cases for aGVHD. A trend for a better survival was seen among patients who started ECP in PR after steroid (80% vs 50% at 2 years; P = 0.07). Overall, 22 (45%) of 49 patients and 17 (35%) of 49 patients with steroid refractory cGHVD achieved CR and PR after ECP, respectively. After a median follow-up of 27 months, 44 (90%) of 49 patients are alive, 21 of whom (48%) are on steroid. CONCLUSIONS Extracorporeal photopheresis is confirmed as an effective second-line treatment in both aGVHD and cGVHD, because it can induce a response in more than 80% of the patients and a long-term survival in at least 50% of the cases.
