Abstract Abstract 218 Background: Graft-versus-leukemia (GVL) effects are closely associated with graft-versus-host disease (GVHD) after allogeneic hematopoietic cell transplantation (HCT). In a reexamination of GVL effects, we evaluated acute and chronic GVHD defined by NIH consensus criteria and immunosuppressive treatment (IST) as risk factors for recurrent malignancy after HCT. Patients and methods: We analyzed a cohort of 2656 consecutive patients with acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), chronic myeloid leukemia (CML), myelodysplastic syndrome (MDS) or myeloproliferative neoplasms (MPN) who received allogeneic HCT after high-intensity conditioning between 1992 and 2005. The onset of NIH chronic GVHD was ascertained by retrospective chart review using follow-up information obtained by our Long Term Follow Up clinic. Rates and hazards of recurrent malignancy and mortality were analyzed according to GVHD and IST as time-varying covariates. To illustrate the effect of time-varying covariates, we calculated the rate of recurrent malignancy per patient-year according to prior GVHD within sequential 90-day intervals after HCT. Cox proportional hazard models were adjusted for potential factors affecting outcomes. Results: The median patient age at HCT was 39 years (range, 0 to 71 years). Donors were HLA-identical relatives (n=1088), HLA-matched unrelated volunteers (n=912), HLA-mismatched relatives (n=243), and HLA-mismatched unrelated volunteers (n=413). GVHD prophylaxis was mostly cyclosporine and methotrexate (n=1885, 71%). Relapse rates per patient-year declined from 3 months until at least 36 months after HCT for patients with prior acute GVHD or NIH chronic GVHD (Figure). Patients without prior GVHD showed a much less pronounced decline between 12 and 30 months after HCT. Adjusted Cox analysis showed that acute GVHD and NIH chronic GVHD were associated with statistically similar reductions in risk of late recurrent malignancy beyond 18 months after HCT, with no incremental effect of chronic GVHD in patients with prior acute GVHD (Table 1). GVL effects were demonstrable in patients with CML or AML but not in those with ALL or MDS/MPN. Discontinuation of IST was associated with a decreased risk of recurrent malignancy among patients without prior GVHD but not among those with prior GVHD (Table 2). Grades III–IV acute GVHD and NIH chronic GVHD with prior acute GVHD were associated with a statistically significant increase in risk of early mortality between 3 and 18 months, but grade II acute GVHD and NIH chronic GVHD without prior acute GVHD were not. Conclusion: Both acute and NIH chronic GVHD are associated with potent GVL effects, but NIH chronic GVHD does not confer any incremental benefit after acute GVHD. Withdrawal of IST was associated with a reduction in risk of recurrent malignancy in patients without prior GVHD. Analyses of GVL effects should account for time from HCT, the history of GVHD, type of malignancy and IST. Immune manipulations such as prophylactic donor lymphocyte infusion or early withdrawal of IST may represent reasonable approaches to decrease the risk of recurrent malignancy in patients without prior GVHD, if the risk of GVHD could be minimized. Disclosures: No relevant conflicts of interest to declare.

Risk Of Relapse

AbstractThis study was conducted to elucidate the influence of immunosuppressive treatment (IST) and GVHD on risk of recurrent malignancy after allogeneic hematopoietic cell transplantation (HCT). The study cohort included 2656 patients who received allogeneic HCT after high-intensity conditioning regimens for treatment of hematologic malignancies. Rates and hazard ratios of relapse and mortality were analyzed according to GVHD and IST as time-varying covariates. Adjusted Cox analyses showed that acute and chronic GVHD were both associated with statistically similar reductions in risk of relapse beyond 18 months after HCT but not during the first 18 months. In patients with GVHD, resolution of GVHD followed by withdrawal of IST was not associated with a subsequent increase in risk of relapse. In patients without GVHD, withdrawal of IST was associated with a reduced risk of relapse during the first 18 months, but the risk of subsequent relapse remained considerably higher than in patients with GVHD. In summary, the association of GVHD with risk of relapse changes over time after HCT. In patients without GVHD, early withdrawal of IST might help to prevent relapse during the first 18 months, but other interventions would be needed to prevent relapse at later time points.

Abstract We have previously described serious graft-versus-host disease (GVHD) as a highly undesirable outcome after allogeneic hematopoietic cell transplantation (HCT). Serious GVHD encompasses death, lengthy hospitalization, major disability, or recurrent major infections related to either acute or chronic GVHD. In a previous study, we found a 25% incidence of serious GVHD among 171 consecutive patients who had HCT after non-myeloablative (NMA) conditioning between January 1998 and May 2002. To put this observation into perspective, we applied the same criteria for serious GVHD in a cohort of 264 consecutive patients who had HCT after myeloablative (MA) conditioning during the same period of time and compared results with those of the previous study. The overall incidence of serious GVHD was 17% (44/264) in the MA group, compared to 25% (43/171) in the NMA group. There were no statistically significant differences in the incidence of grades III–IV GVHD, extensive chronic GVHD or nonrelapse mortality between the two groups (Table). Patients in the NMA group were older and had higher comorbidity scores than those in the MA group. In the univariate analysis, the hazard ratio (HR) of serious GVHD for the NMA group compared to the MA group was 1.71 (95% C.I., 1.1–2.6) (p = 0.01). After adjusting for patient age, patient and donor gender, donor type, HLA-mismatch, aggressive versus indolent malignancy at HCT, remission versus relapse at HCT, myeloid versus non–myeloid malignancy, HCT co–morbidity index, and prior donor lymphocyte infusion, the HR of serious GVHD was 1.50 (95% C.I., 0.8–2.7) (p = 0.17). After censoring for recurrent or progressive malignancy after HCT, the cumulative incidence of serious GVHD at 3 years was 21% for the NMA group and 14% for the MA group, and the HR was 1.33 (95% C.I., 0.7–2.6) (p = 0.40). Reasons for categorization of GVHD as serious (i.e., death, lengthy hospitalization, major disability, or recurrent major infections) were similar between the MA and NMA cohorts. Among the 44 patients with serious GVHD in the MA group, 19 (43%) had serious acute GVHD, and 25 (57%) had serious chronic GVHD. Among the 43 patients with serious GVHD in the NMA group, 20 (46%) had serious acute GVHD, and 30 (70%) had serious chronic GVHD. Among the 264 MA patients, 28 (11%) had grade III–IV acute GVHD and 147 (56%) had extensive chronic GVHD that did not meet the criteria for serious GVHD, compared to 7 (4%) and 84 (49%) of the 171 NMA patients, respectively. We conclude that the type of pretransplant conditioning regimen does not have a large effect on the incidence of serious GVHD after HCT. Assessment of serious GVHD provides additional useful information to acute GVHD grades and the classification of limited and extensive chronic GVHD in describing overall GVHD-related outcomes after HCT.

Abstract Refractory extensive chronic graft-versus-host disease (GVHD) after allogeneic stem-cell transplantation (SCT) is associated with high mortality [Margolis J., SeminOncol 2000].However, conventional therapies including steroids are often unsuccessful in those patients with multiorgan involvement and are associated with significant therapy-related complications and poorly life quality. Mesenchymal stem cells (MSCs) have immunomodulatory effects [Tse WT et al., Transplantation 2003; Spees JI et al.,Proc Natl Acad Sci USA 2003]. Recently MSCs have been given intravenously to treat seven steroid resistant acute GVHD patients and one patient with chronic GVHD. MSCs effects in chronic GVHD is rarely known, although this successfully experience suggests that MSCs have been well tolerated and had a powerful immunosuppressive effects on acute GVHD. [Katarina Le Blanc et al., Lancet 2004; Olle Ringden., Transplantation 2006 ]. Here, we present our experience of using MSCs for treatment of Thirteen patients with refractory chronic GVHD. Between May 2005 and March 2007, thirteen patients (8 male, 5female) with hematological malignancies with a median age of 26(range:15 to 40) years who had received peripheral stem cells from sibling donors. All patients developed steroid resistant or extensive chronic GVHD, with progressive involvement of the skin(13), liver(10), oral mucosa(12),ocular glands(12), and thrombocytopenia (1) when the immunosuppressive agents were taped after five to twenty-four months. The MSC dose was median 1.0 ×106 cells/kg body weight of the recipient. In all, thirteen patients had at least received one dose, seven patients received more than two doses. MSC donors were in seven cases HLA-identical siblings, six unrelated mismatched donors. No side-effects were seen after MSCs infusions. All patients have responded after follow-up of the median time 15 months. One patient with moderate cGVHD had a complete responses, and discontinued all of the immunosuppressive agents without relapse more than 18.4 months after MSC infusion. Three moderate and two patients with severe chronic GVHD improved to mild degree, and six severe turned to moderate degree. Complete resolution was seen in gut(2/3), liver(5/10), skin(5/13), oral(6/12) and eye(2/12). One patient responded in skin, liver, oral mucose and eye, but developed in lung (bronchiolitis obliterans, BO) score of 2 which are considered severe chronic GVHD. Mean follow-up periods was 27m (rang: 14 to48m), Leukemia free survival(LFS)rate were 85%(11/13), and the overall survival (OS)rate were 92.3%(12/13). Our experience suggests that MSC infusion is a safe and effective adjunct therapy for refractory extensive chronic GVHD with resistance to conventional therapy. But more prospective, controlled studies with MSCs for treatment of GVHD should be performanced to evaluate this new treatment exactly.

Abstract We previously reported 2-year overall survival (OS) of 65% among 33 pts with MCL given nonmyeloablative HCT (Blood2004; 104: 3535). Here, we update our results on the initial 33 pts with median follow up of 63 months and report on 20 additional pts with emphasis on: long-term disease control and resolution of chronic GVHD. Pts were conditioned with 2Gy TBI with or without fludarabine (90 mg/m2). Median age for all pts was 56 (range 33–75) years and median number of prior regimens was 4. Forty percent of pts had failed high-dose autologous HCT and an additional 11% had planned autologous HCT before allograft (4 pts had refractory disease and 2 were in PR). Comorbidity scores of ≥3 were found among 40% of pts. Forty percent of pts were not in CR/PR at HCT and 26% and 21% had marrow infiltration and lymph node size ≥5 cm, respectively. Donors were related (n=28) or unrelated (n=25). After HCT, incidences of grades II, III, and IV acute GVHD were 25%, 13%, and 9% respectively, and chronic extensive GVHD was 53%. Complete (CR) and partial remissions (PR) were seen in 71% and 3% of pts with measurable disease at HCT, respectively. Estimated 5-year rates of non-relapse mortality (NRM), progression/relapse, OS, and progression-free survival (PFS) were 27%, 22%, 58%, and 52%, respectively (Table 1). Among 19 pts in CR at HCT, 11 are alive and in CR, 7 died in CR, and one relapsed (now in CR after Rituximab and donor lymphocyte infusion). Among 13 in PR at HCT, 10 achieved CR and are alive, one died in PR, and 2 died from relapse. Among 21 pts with refractory/relapsed disease at HCT, 12 achieved CR and are alive, 2 have stable disease and are alive, and 7 relapsed (2 are alive in CR and PR after further treatment). At 5-years, 44% and 14% were alive without or with chronic GVHD requiring immunosuppression (Figure); and median duration of treatment for chronic GVHD was 33 months. Outcomes were comparable among related and unrelated recipients. Relapse rates were 47% vs. 14% among pts with vs. without LN size of ≥5 cm (p=0.02) and NRM was 41% vs.17% (p=0.05) among pts with HCT-CI scores of ≥3 vs. 0–2, respectively. Nonmyeloablative HCT is a potentially curative therapeutic modality for pts with advanced MCL, including patients who were chemotherapy-refractory, with a median PFS beyond 5 years. Sustained remissions and continuing resolution of chronic GVHD were observed with extended follow up. Pts with bulky LN might benefit from further debulking strategies before HCT.

Abstract Risk factors for grades 2-4 acute graft-versus-host disease (GVHD) and for chronic GVHD as defined by National Institutes of Health consensus criteria were evaluated and compared in 2941 recipients of first allogeneic hematopoietic cell transplantation at our center. In multivariate analyses, the profiles of risk factors for acute and chronic GVHD were similar, with some notable differences. Recipient human leukocyte antigen (HLA) mismatching and the use of unrelated donors had a greater effect on the risk of acute GVHD than on chronic GVHD, whereas the use of female donors for male recipients had a greater effect on the risk of chronic GVHD than on acute GVHD. Total body irradiation was strongly associated with acute GVHD, but had no statistically significant association with chronic GVHD, whereas grafting with mobilized blood cells was strongly associated with chronic GVHD but not with acute GVHD. Older patient age was associated with chronic GVHD, but had no effect on acute GVHD. For all risk factors associated with chronic GVHD, point estimates and confidence intervals were not significantly changed after adjustment for prior acute GVHD. These results suggest that the mechanisms involved in acute and chronic GVHD are not entirely congruent and that chronic GVHD is not simply the end stage of acute GVHD.

Abstract Background: Graft-versus-host disease (GVHD) remains a major cause of morbidity and mortality after allogeneic hematopoietic cell transplantation (HCT). The combination of tacrolimus (Tac) and methotrexate (MTX) is a standard regimen for GVHD prophylaxis; however, it is associated with several toxicities and patients are often not able to complete the full MTX regimen. The combination of Tac, reduced dose ("mini")-MTX, and mycophenolate mofetil (MMF) has been investigated with a well-tolerated toxicity profile and low incidence of GVHD, although comparison with standard dose MTX has not been done. We performed a randomized non-inferiority trial comparing Tac/MTX (Full-MTX) to Tac/mini-MTX/MMF (Mini-MTX) for prevention of GVHD after myeloablative related and unrelated donor HCT. Methods: Patients <70 years in age receiving first myeloablative allogeneic HCT using 8/8 HLA-matched related or unrelated donor were eligible; all diagnoses and both bone marrow and peripheral blood stem cell grafts were allowed. Full-MTX patients received MTX dose of 15 mg/m 2 day +1, and 10 mg/m 2 days +3, +6, and +11. Mini-MTX patients received doses of 5 mg/m 2 on days +1, +3, and +6 plus MMF 1000 mg BID. MTX and MMF doses were adjusted for body weight in pediatric recipients. Primary endpoints were incidence of acute GVHD, mucositis, and hematopoietic engraftment. Secondary endpoints included incidence of chronic GVHD, organ toxicity, infection, relapse, non-relapse mortality (NRM), and overall survival (OS). Based on our local incidence rates, 45 patients/arm were needed to detect a hazard ratio of at most 1.7 for acute GVHD (no difference between two arms) using a one-sided non-inferiority log-rank test with 5% significance and 80% power. Results: We enrolled 101 patients; 5 were excluded due to change in eligibility or withdrawal of consent prior to HCT. Analysis is based on 96 patients who were randomized to receive Full-MTX (N=49) or Mini-MTX (N=47). Patient characteristics are described in the Table, and were generally balanced between the two groups . All patients in the Mini-MTX arm received their 3 planned doses of MTX; in the Full-MTX arm, 71% received all 4 doses, 26% received 3 doses, and 1 patient received 2 doses of MTX. There was no significant difference in cumulative incidence of grade 2-4 acute GVHD by day 100 between arms (28% Mini-MTX vs 27% Full-MTX, P=0.41) (Figure 1); however, there was a trend toward higher grade 3-4 acute GVHD in Mini-MTX arm (13% vs 4%, P=0.07). Mini-MTX recipients had lower incidence of severe WHO grade 3-4 mucositis (57% vs 82%, P=0.010), shorter duration of mucositis (median 11 vs 18 days, P<0.001), and had faster engraftment of both neutrophils (median 15 vs 17 days, P<0.001) and platelets (median 23 vs 27 days, P=0.023), with resultant shorter hospital stay (median 27 vs 31 days, P<0.001). There were no significant differences between the two arms in any grade of chronic GVHD (36% vs 25%, P=0.09) or moderate-severe chronic GVHD at 1 year (23% vs 20%, P=0.14). There were also no differences in bacterial (P=0.18), viral (P=0.52) or fungal (P=0.74) infections. There were no significant differences in hepatotoxicity, but lower proportion of patients receiving Mini-MTX experienced nephrotoxicity (creatinine ≥3X upper limit of normal: 2% vs 26%, P<0.001). Mini-MTX recipients also had less respiratory failure in the first 6 months (6% versus 22%, P=0.026). There was no difference in relapse between arms (2-year incidence 22% vs 21%, P=0.89), although Mini-MTX was associated with lower NRM (11% vs 25% at 2 years) (Figure 2), and non-significant but higher OS (70% vs 52% at 2 years; P=0.06). Conclusions: Compared to Full-MTX, a Mini-MTX regimen that incorporates MMF was associated with no difference in acute or chronic GVHD incidence and a more favorable toxicity profile, with faster engraftment, less mucositis, less organ toxicity, and lower NRM. The combination of Tac/mini-MTX/MMF is an acceptable alternative to Tac/MTX after myeloablative related and unrelated donor HCT. Figure 1 Figure 1.

Background: Haploidentical hematopoietic cell transplantation (HCT) provides an alternative option for patients without HLA-matched donor. GVHD, engraftment failure, and infectious complications continue to be the main causes of non-relapse mortality (NRM). We hypothesized that selective depletion of TCRαβ+ and CD45RA+ naïve T cells subset will permit hematopoietic engraftment, while effectively reducing GVHD, and provide improved donor immune reconstitution through adoptive transfer of donor's mature NK cells, γδ T cells and CD45RO+ memory T cells. Methods: Mobilized PBSC product were divided into two fractions in 9:1 ratio, and depleted using CliniMACS device after labeling with TCRαβ and CD45RA reagents (Miltenyi Biotec, Bergish-Gladbach, Germany), respectively. The conditioning regimen consisted of fludarabine 160 mg/m2 divided daily over 4 days, thiotepa 10 mg/kg divided twice daily for 1 day and melphalan 70-140 mg/m2 for 1 day, in combination with total lymphoid irradiation 6 Gy (n=23), or 7.5 Gy (n=12) over 3 equal fractions, or total body irradiation of 2 Gy (n=2). Short term GVHD prophylaxis for 30 days was given to 1 patient using MMF, 25 patients using tacrolimus and 2 patients using sirolimus. Results: We transplanted 37 patients, including 32 adults (median age 47 years, range 20 - 69) and 5 children (median age 13 years, range 7-15 years) with high risk AML (n=17), ALL (n=11), MDS (n=5), myeloma (n=1), mast cell leukemia (n=1), acute undifferentiated leukemia (n=1) or NK/T lymphoma (n=1). The patients were infused with TCRαβ and CD45RA depleted graft containing a median of 8.65 x 106 (range, 3.54 - 20.78) CD34+ cells/kg, 0.00 x 104 (range 0 - 0.97) CD45RA+CD3+ cells/kg, and 2.4 x 106 (range, 0.15 - 11.67) CD45RO+CD3+ cells/kg. The TCRαβ depleted graft fraction contained a median of 0.19 x 104 (range 0 - 8.53) TCRαβ+ cells/kg, and 8.76 x 106 (range 1.73 - 30.00) TCRγδ+ cells/kg. Only 1 patient experienced primary graft failure. All others had engraftment of ANC > 500 cells/µL at a median of 10 day (range, 8 - 22) and PLT > 20,000 cells/µL at a median of 12 day (range, 7 - 19). There was no secondary graft failure. Four patients with high titers of donor-specific HLA antibodies (DSA) engrafted successfully after effective desensitisation with plasma exchange, rituximab and immunoglobulin. Fourteen patients (38%) developed acute GVHD of grade II-IV (Gd II n=9 ; Gd III n=4 ; Gd IV n=1 ). Only one patient experienced chronic GVHD, giving 2 year cumulative incidence (CI) of chronic GVHD of 3.9 %. Day 180 CI of NRM and relapse were 22.7 % (95% 10.5-37.7%) and 12.0 % (95% CI 3.7-25.7%), respectively. NRM was attributed to aGVHD in 3 of the 13 deaths. Viral reactivation included CMV (n=13), HHV6 (n=4), EBV (n=3) and adenovirus (n=4), with no fatal viral infection occurred within 180 days. Seven patients died of infection, including 3 patients who had fatal blood stream infection (bacteria n=2; fusarium n=1) within 180 days. With a median follow up of 436 days (range 20- 916 days) in surviving patients, the 6 month and 2 year overall survival (OS) were 77.2% (95% CI 59.4-87.9%) and 57.7 % (95% CI 37.6-73.4%), respectively (Figure 1). The 2-year OS for patients with intermediate risk and high/very high risk disease risk index (DRI) were 60% and 24%, respectively (p=0.07) (Figure 2). Conclusions: Our preliminary results suggest that RIC haplo-HCT with TCRαβ and CD45RA+ depleted grafts allows successful allograft in high-risk patients lacking a suitable matched donor, including patients with high level of donor-specific HLA antibodies. Acute GVHD was generally abortive, leading to chronic GVHD in <5% of the patients. Fatal viral infection was not observed. Further efforts are needed to lower the risk of death due to bacterial infection, and also relapse in patients with high risk DRI, such as antibiotic prophylaxis or repeated doses of memory-cell DLI.

Post-transplant cyclophosphamide (PTCy) in combination with tacrolimus and mycophenolate mofetil (MMF) has been used increasingly in recent years to prevent graft-versus-host disease (GvHD) in patients undergoing hematopoietic cell transplantation (HCT), and has been proven safe and effective regardless of HLA matching criteria. Historically, the therapeutic dose level recommended for tacrolimus has ranged from 10 to 15 ng/mL, when combined with methotrexate, and between 5-10 ng/mL when combined with sirolimus. However, data on the optimal starting dose and serum level of tacrolimus when combined with PTCy does not exist. Given tacrolimus's broad inhibition on T-cells activation and the PTCy's selective inhibition on alloreactive T-cells, we hypothesized that lower serum levels of tacrolimus could suffice to achieve optimal transplant outcomes. We retrospectively identified a consecutive case series of 219 patients who received HCT with PTCy (50 mg/kg on days +3 and +4) in combination with tacrolimus and MMF (day +5) as GvHD prophylaxis at City of Hope from January 2011 to June 2018. Tacrolimus was delivered with continuous intravenous infusion until engraftment, then switched to equivalent oral dose. Tacrolimus dosing was weight-based (WBD) in 80 patients and fixed dose (FD) of 1 mg in 139 patients. We captured Tacrolimus levels at two different time points: 1. the initial steady state (ISS) and 2. at engraftment level (EL) to identify which time point will correlate with better HCT outcomes. At each time point, transplant outcomes were compared between patients with serum levels ≥10 ng/mL and <10 ng/mL. We analyzed and compared the overall survival (OS), progression-free survival (PFS), relapse rate, non-relapse mortality (NRM), cumulative incidence of Grade 2-4 acute GVHD and chronic GVHD between the two groups by univariate and multivariate analysis. P values were 2 sided at a significance level of 0.05. Correlation between method of administration and serum level of tacrolimus was examined by chi-square test. Patients received HCT either from a haploidentical (n=175), matched (n=6), or mismatched donor (n= 38). Tacrolimus levels at the ISS (median: day +9 of HCT, range 8-16) was <10 ng/mL in 181 patients with median age of 52 years (interquartile range: 30-62) and ≥ 10 ng/mL in 38 patients with median age of 39 years (interquartile range: 18-55), (P = 0.004). Regardless of the conditioning regimen, tacrolimus level at ISS was <10 ng/ml in majority of patients (81% in myeloablative conditioning and 84 in reduced intensity conditioning). Majority of patients (91%) who received peripheral blood stem cells as graft source were more likely to have tacrolimus levels <10 ng/ml, whereas 56% of patients who received bone marrow as graft source had tacrolimus levels <10 ng/ml. Lastly, majority of patients (89%) who received tacrolimus at the FD had a serum level of <10 ng/mL at ISS as compared to 73% of patients who received the drug at WBD of the drug (P=0.003) At ISS, 18 months OS, PFS, relapse rate were 64%, 58% and 19%, respectively, in patients with tacrolimus level <10 ng/mL, which compared favorably to 48%, 45%, and 35%, respectively, in patients with Tacrolimus level ≥10 ng/mL (Figure 1). In multivariable analysis, patients with tacrolimus level <10 ng/mL had lower relapse rate (HR= 0.53; 95% CI: 0.26-1.05 p=0.067) and better PFS (HR=0.50; 95% CI: 0.31-0.82, P= 0.006). While no difference was seen in OS (p= 0.76), cumulative incidence of NRM (P=0.59), acute GVHD grade II-IV (P=0.23), grade III-IV (P=0.46) or chronic GVHD (p=0.38) between the two groups at the ISS. In the multivariable analysis and after adjusting for all baseline and clinically relevant variables, EL did not correlate with any outcome In conclusion, tacrolimus dosing at a FD was more likely resulting in ISS of 4-10 ng/mL (86% of patients in <10 ng/mL group). ISS tacrolimus levels of less than 10 ng/mL was correlated with lower relapse rate and better PFS, without a significant increase in GVHD or NRM.

Background: Haploidentical hematopoietic cell transplantation (HCT) provides an alternative option for patients without HLA-matched donor. Graft-versus-host disease (GVHD), engraftment failure, and infectious complications continue to be the main causes of non-relapse mortality (NRM). We hypothesized that selective depletion of TCRαβ+ and CD45RA+ naïve T-cells subset will permit hematopoietic engraftment, while effectively reducing GVHD, and provide improved donor immune reconstitution through adoptive transfer of donor's mature NK-cells, γδ T-cells, and CD45RO+ memory T-cells. Methods: Mobilized PBSC products were divided into two fractions in 9:1 ratio and depleted using CliniMACS device after labeling with TCRαβ and CD45RA reagents (Miltenyi Biotec, Bergish-Gladbach, Germany), respectively. The conditioning regimen consisted of fludarabine 160mg/m2 divided daily over 4 days, thiotepa 10mg/kg divided twice daily for 1 day, and melphalan 70-140mg/m2 for 1 day, in combination with total lymphoid irradiation 6Gy (n=35) or 7.5Gy (n=12) over 3 equal fractions, total body irradiation of 2Gy (n=13) or antithymocyte globuline (n=2). Short term GVHD prophylaxis for 30 days was given to 1 patient using MMF, 50 patients using tacrolimus, and 2 patients using sirolimus. Results: We transplanted 62 patients, including 55 adults (median age, 47 years; range 20-69) and 7 children (median age, 13 years, range 7-17) with high risk AML (n=34), ALL (n=15), MDS (n=7), plasma cell neoplasm (n=2), mast cell leukemia (n=1), acute undifferentiated leukemia (n=1), and NK/T-cell lymphoma (n=1). The patients were infused with TCRαβ and CD45RA depleted graft containing a median of 6.79 x 106 (range 3.54-20.78) CD34+ cells/kg, 0.00 x 104 (range 0-0.97) CD45RA+CD3+ cells/kg, and 1.09 x 106 (range 0.15-11.67) CD45RO+CD3+ cells/kg. The TCRαβ depleted graft fraction contained a median of 0.20 x 104 (range 0-11.30) TCRαβ+ cells/kg, and 8.52 x 106 (range 0.62-30.00) TCRγδ+ cells/kg. Only 1 patient experienced primary graft failure. All others had engraftment of ANC &gt; 500 cells/µL at a median of 10 days (range 8-22) and platelet &gt; 20,000 cells/µL at a median of 12 days (range 8-22). There was no secondary graft failure. Six patients with high titers of donor-specific HLA antibodies (DSA) engrafted successfully after effective desensitisation with plasma exchange, rituximab, and immunoglobulin. Twenty-two patients (35%) developed acute GVHD of grade II - IV (Gd II, n=15; Gd III, n=5; Gd IV, n=2). Three patients experienced chronic GVHD, giving 2-year cumulative incidence of 7 %. Day 180 cumulative incidence of NRM and relapse were 24.8% (95% CI 14.3-36.8%) and 14.9% (95% CI 6.3-27.0%), respectively. Four of the 16 NRM were attributed to aGVHD. Viral reactivation included CMV (n=25), HHV-6 (n=14), EBV (n=11), and adenovirus (n=7). Fourteen patients died of infection, including 5 patients who had fatal blood stream infection (bacteria, n=3; candidemia, n=2) and 1 patient from disseminated adenovirus infection within 180 days. With a median follow-up of 298 days (range 21-1298) in surviving patients, the 2-year overall (OS), event-free (EFS), and GVHD-free/relapse-free (GRFS) survival were 58% (95% CI 37.6-73.4%), 43% (95% CI 27-57%), and 39% (95% CI 24-54%), respectively (Figure 1). In multivariable analysis, only HCT-comorbidity index (HCT-CI) showed significant impact on OS (HR 6.24; 95% CI 2.05-19.05; p=0.0013), EFS (HR 4.80; 95% CI 1.73-13.35; p=0.0027), and RRM (HR 6.49; 95% CI 1.44-29.25; p=0.015), whereas disease risk index (DRI) impacts risk of relapse (HR 4.50; 95% CI 1.39-14.52; p=0.012). The 2-year OS, EFS, and GRFS for the subset of 30 patients (adults, n=25; children, n=5) with HCT-CI score of 0 and low/intermediate risk DRI were 68%, 68%, and 60%, respectively (Figure 2). Conclusions: Our preliminary results suggest that RIC haplo-HCT with TCRαβ and CD45RA+ depleted grafts allowed successful allograft in high-risk patients lacking a suitable matched donor, including patients with high level of DSA. Acute GVHD was generally abortive, leading to low incidence of chronic GVHD. The best outcome is seen in patients with favorable HCT-CI and DRI. Further efforts are needed to lower the risk of death due to blood stream infection, and relapse in patients with high risk DRI, such as optimisation of anti-microbial prophylaxis or repeated doses of memory-cell donor lymphocyte infusion (DLI).

Abstract Abstract 2319 Background: Graft-versus-host disease (GVHD) is a common immunologic complication after allogeneic hematopoietic cell transplantation (HCT). Cyclosporine or tacrolimus in combination with other agents represent widely accepted standards of care as immunosuppressive regimens after HCT. Results of open-label randomized prospective phase III studies have indicated that the risk of grades II-IV acute GVHD after bone marrow transplantation with related or unrelated donors is lower with the use of tacrolimus as compared to cyclosporine, in combination with methotrexate. The current study was carried out to compare results with tacrolimus versus cyclosporine after HCT with G-CSF-mobilized blood cells. Patients and methods: The study cohort included 510 consecutive patients who received a first G-CSF-mobilized blood cell graft from related or unrelated donors after high-intensity conditioning for treatment of hematological malignancies between 7/1/2003 and 2009 at our center. All patients received ursodeoxycholic acid from 2 weeks before conditioning until 90 days after HCT to prevent hepatic complications, and all patients received immunosuppression with either tacrolimus or cyclosporine in combination with methotrexate after HCT. Endpoints included grades II-IV acute GVHD, grades III-IV acute GVHD, chronic GVHD, end of treatment for chronic GVHD, overall survival, disease-free survival, recurrent malignancy and nonrelapse mortality. Multivariate Cox regression models were used to evaluate hazard ratios for these endpoints with tacrolimus as compared to cyclosporine. The models were adjusted for patient age, donor type, recipient and donor gender combination, disease type, disease risk category, use of total body irradiation in the conditioning regimen, and year of HCT. The analysis was carried out as of July, 2010. Results: The median age of patients was 47 (range, 1 to 66) years. Diagnosis at HCT was acute myeloid leukemia in 200 (39%) patients, acute lymphoblastic leukemia in 73 (14%), chronic myeloid leukemia in 49 (10%), myelodysplastic syndrome or myeloproliferative disorders in 160 (31%) and other lymphoid malignancies in 28 (5%). Total body irradiation was used for conditioning in 168 (33%) patients. Of the 510 patients, 277 (54%) had HLA-matched related donors, 203 (40%) had HLA-matched unrelated donors, and 30 (6%) had HLA-mismatched related or unrelated donors. Outcomes according to immunosuppression with tacrolimus or cyclosporine are shown in Table 1. Multivariate analysis showed no statistically significant differences between tacrolimus and cyclosporine for any of the endpoints tested (Table 2), although the results showed a trend suggesting that the risk of non-relapse mortality might be lower with tacrolimus as compared to cyclosporine. Conclusion: In this retrospective analysis, tacrolimus offered no statistically significant advantage over cyclosporine for preventing grades II-IV acute GVHD after HCT with G-CSF-mobilized blood cells, and results for other outcomes also showed no statistically significant differences. Although our data support the hypothesis that either regimen could be an acceptable standard of care for immunosuppression, the number of patients analyzed in this study is not sufficient to completely exclude clinically meaningful differences in outcomes with the two regimens.
