Abstract Background: AML incidence increases with age. Allogeneic stem cell transplantation (Allo-SCT) offers the best leukemic control but is associated with high non-relapse mortality (NRM). Recent advances using non-myeloablative strategies have established the feasibility of allo-SCT in elderly patients. However in the context of AML, an important reduction of the intensity of the preparative regimen may be also associated with a loss of leukemic control, offsetting the impact of toxicity reduction in elderly. Methods: We retrospectively analyzed AML patients in first complete remission (CR1) reported to the SFGM-TC, aged above 55 and transplanted from a HLA identical sibling donor prior to 01/01/05. Results: 62 patients prepared with a non-myeloablative conditioning (NMAC) (fludarabine (75mg/m2) + TBI (2Gy)) (N=14) or a reduced intensity conditioning (RIC) (busulfan (4 to 8 mg/m2) + fludarabine (150 to 180 mg/m2) + thymoglobulin (2.5 to 12.5 mg/m2)) (N=48). GVHD prophylaxis used CSA+MMF for NMAC, CSA +/− MMF for RIC. With few exceptions, all patients in a given centre were treated identically. Major characteristics were: age 58 (55–67), M/F= 27/35. Time between diagnosis and allo-SCT: 171 days (101–467). BMT/PBSCT: 7/55. Pts have been considered for allo-SCT because of poor prognosis factors: no favorable cytogenetics (100%), secondary AML (15%), 2 chemotherapy course to achieve CR1 (24%) or M0, M6 or M7 FAB (20%). All pts engrafted. Acute GVHD occurred in 16 pts (grade 1: 6; grade 2: 6; grade 3–4: 4) and chronic GVHD in 18 pts (limited: 8; extensive: 10) with no difference in the 2 groups. The cumulative incidences of grade 2–4 aGVHD and cGVHD were 16% (95%CI: 7–25) and 29% (95%CI: 18–40) respectively. 15 pts relapsed and 8 died from NRM. Relapse and NRM cumulative incidences were 24% (95%CI: 13–35) and 13% (95%CI: 5–21) respectively. 49 pts were evaluable for cGVHD: of the 18 expressing cGVHD none have relapsed as compared to 12 of the 31 who did not present cGVHD (39%, 95%CI: 22–56) (p=.007). The 2 year KM survival and DFS probabilities are 63% (47–76) and 56% (42–69). In a landmark analysis investigating patients alive on day 100, 2 year DFS are 94% and 38% respectively with or without cGVHD (p=0.001) and 2 year KM OS are respectively 94% and 45% (p=0.01). Conclusions: We conclude that such a strategy in elderly can afford a high relapse control with low NRM conducting to high survival probability at 2 years. Results are achieved through the allogeneic effect as expressed by cGVHD inviting to a careful immunomodulation in the early post transplant period to further improve results.

Abstract Abstract 4456 The increasing use of the novel agents, lenalinomide and bortezomib, in the treatment of multiple myeloma (MM) has contributed to higher complete remission (CR) rates and longer overall (OS) and event free survival (EFS). We assessed the impact of these drugs on the outcome of high-risk MM patients treated with allogeneic stem-cell transplantation (allo-SCT) after reduced-intensity conditioning (RIC) over the last 10 years in our program. This retrospective study compared 45 patients (group1) transplanted in our centre between January 1999 and January 2006 and who had not received either novel agent prior to transplant (as induction or relapse therapy) with 34 patients (group 2) transplanted between January 2006 and June 2010 who received either one or both drugs before allo-SCT. The median time between diagnosis and Allo-SCT was 37 months (6–161) and 41 months (9–145) in the two groups respectively (p=NS). The median time between auto-SCT and allo-SCT was 9 months (2–89) and 27 months (2–49) respectively (p<0.0001). 36 patients (80%) in the first group vs. 8 patients (24%) in the second group received a tandem auto allo-SCT (p<0.0001). The disease status at transplantation was in CR in 2 patients (4%) vs. 10 patients (29%) and PR or stable disease in 35 patients (78%) vs. 21 patients (62%) in the first and the second group respectively (p<0.0033). in the table 1 we resumed some important data.

Groups differ in several aspects: In recent years allogeneic transplant was considered rather as salvage therapy in patients relapsing after auto-SCT than in a tandem auto-allo strategy, patients with cytogenetic aberrations (p<0.005), and stem cell source from unrelated donor (13 patients (38%) vs. none) (p<0.0004), and two days of anti-thymoglobuline (ATG 2,5mg/kg/day). (P<0.001), in the second group. Table 1 The median follow-up after transplant was 45 (2–127) and 16 (3–39) months in the first and second group respectively (p<0.001). The cumulative incidence of acute graft versus-host disease (GVHD) tended to be higher before 2006 (47% vs. 24%; p=0.0584). The cumulative incidence of chronic GVHD was statistically different (56% vs. 30%; p=0.0241). The estimated probability of TRM at day 100 was 12% in the first group vs. 0 % in the second group (p=0.077) and did not differ between groups at 2 years. (18% vs. 23% (p =0.537)). The overall survival (OS) at two years was 60% vs 70% in the first and second group respectively (p=0.1784). The progression-free survival (PFS) tended to be different at 2 years (45% vs. 65% (p=0.056)). The median of PFS is 22 months for patients transplanted prior 2006 and is not reached in the second group (p=0.1811). In our study there was no significant difference in OS or TRM between the 2 groups in multivariate analysis; only the number of previous auto-SCT with more than two high dose chemotherapies has a negative impact on the OS. There was a significant difference in the incidence of relapse between the 2 groups in the multivariate analysis. Although we cannot carry out the impact of other changes related to our practice in the same period, these data suggests an impact in transplant outcomes of novel drugs introduced in the therapy of MM (lower TRM, GVHD and higher disease control). This piece of information, if confirmed, should be taken into considerations for present and future approaches. Disclosures: No relevant conflicts of interest to declare.

Abstract Introduction: Little is known regarding the impact of hematopoietic and immune recoveries after double umbilical cord blood (dUCB) allogeneic stem cell transplantation (allo-SCT), especially after the TCF (low dose 2 Grays total body irradiation + cyclophosphamide 50 mg/Kg 1 day + fludarabine 200 mg/m² 5 days) reduced-intensity conditioning (RIC) regimen, which is considered as a standard RIC regimen for dUCB allo-SCT in adults Patients and Methods: Here we considered a homogeneous cohort of 47 patients (males: n=24; median age: 55.5 years (range: 17.5-69) who engrafted after a dUCB TCF allo-SCT performed between November 2006 and April 2013 in our department. Fifty-three percent of the patients had myeloid disease. The majority of cases were in complete remission at time of transplant (72.3%). GVHD prophylaxis consisted of cyclosporine + mycophenolate mofetyl in all cases. All patients received G-CSF from day 1 until neutrophils recovery. The median nucleated cells dose infused was 4.17 107/kg. The aim of the study was to investigate the impact on outcomes of the recovery of the following cellular subsets: leucocytes, monocytes, lymphocytes, neutrophils at day +30 and day +42, and CD4+, CD8+ T cells, B and NK cells at day+100. Results: Median times for neutrophils and platelets recoveries were 17 days (range: 6-59) and 37 days (range: 0-164), respectively. With a median follow-up of 30.4 months (range: 2.8-77.5), the 3-year overall and relapse-free survivals (OS, RFS), relapse incidence (RI), and non-relapse mortality (NRM) were 65.7%, 57.2%, 27.1% and 19%, respectively. The cumulative incidences of grade II-IV and grade III-IV acute GVHD were 38.3% and 10.6%, respectively, while, 3-year incidence of chronic GVHD was 53.5% (limited 42%, extensive 11.5%). In univariate analysis, 3-year OS was significantly higher in case of lymphoid disease (80.9% vs 51.9%, p=0.05) or when achieving at day+30 or day +42 higher counts of leucocytes (> median: 2760/mm3; 79% vs 51%, p=0.05; median > 4250/mm3; 78.6% vs 55.4%, p=0.04) or monocytes (> median: 615/mm3; 87.5% vs 45.8 %, p=0.02; median > 830/mm3, 86.2% vs 54.1%, p=0.03). Older age (>median: 55 years) and higher monocytes count at day +42 (> median: 830/mm3) were significantly associated with higher 3-year RFS (63.6% vs 49.1 %, p=0.046; and 75.7 vs 44.4%, p=0.014). Higher leucocytes count at day +42 (>median: 4250/mm3) was the only factor associated with significant 3-year lower NRM (7.1% vs 31.7%, p=0.04), while younger age was associated with higher risk of grade 3-4 acute GVHD (16.7% vs 4.4 %, p=0.05). No factor was predictive of chronic GVHD in this series. In multivariate analysis, older age and early higher monocytes count after transplant were the two independent factors associated with a significantly higher OS (>55 years, HR: 0.21; 95%CI: 0.05-0.85, p=0.028; >615/mm3 at day +30, HR: 0.05; 95%CI: 0.01-0.43, p=0.006) while only older age remained independently associated with better RFS (>55 years, HR: 0.25, 95%CI: 0.08-0.78, p=0.017). No factor was predictive of NRM, grade 2-4 GVHD, grade III-IV acute or chronic GVHD. Conclusion: These results suggest that higher early monocytes recovery is predictive of outcome after dUCB TCF RIC allo-SCT in adults. Immune recovery seems to have no impact on survivals in this series while influence of age has to be confirmed by other studies. Our results pave the way for future studies aiming to closely and prospectively monitor the kinetics of hematopoietic and immune recoveries after this type of graft. As all patients received G-CSF after transplant, other immunostimulatory cytokines should be tested to ensure sufficient hematopoietic recovery in the setting of adult dUCB TCF RIC allo-SCT.

6547 Background: Reduced-intensity allogeneic stem cell transplantation (RIT) has emerged as an alternative to myeloablative transplantation in pts with myelodysplastic syndrome (MDS). Given the uncertainty regarding the appropriate conditioning, SFGM-TC conducted a retrospective multicenter study with the attempt to evaluate the impact of conditioning on pts’ outcome. Methods: The record of 61 pts (37 males) with MDS who received a RIT between 1998 and 2003, from 22 French transplantation centres, were reviewed. According to the FAB classification, 11 pts had RA at diagnosis, of whom one had progressed to REAB and one to AML before transplantation. Thirty-two pts had REAB, of whom 2 had progressed to REAB-T and 7 to AML. Twelve pts had REAB-T and 6 CMML, of whom 8 progressed to AML. The median time from diagnosis to RIT was 12 months (6–129). Conditioning regimen consisted of fludarabin (Flu) plus busulfan ( n=29), Flu plus 2-Gy TBI ( n=20) and idarubicin plus aracytine and Flu (n=12). Donors were HLA-identical siblings (n=52) and HLA-matched unrelated (n=9). All pts received peripheral blood stem cells. The median of CD34+ infused cell dose was 5 × 106/kg (0.5–17.3). Results: At the reference date of 1 July 2005, median follow-up was 44.7 months (21–85). Estimated 3-year overall survival (OS), progression free survival (PFS), relapse and transplant-relapse mortality (TRM) were 35%, 27%, 66% and 30%, respectively. Neither of the 3 conditioning regimens used had impact on pts’ outcome. In multivariable analyses, while acute III/IV grade GVHD development was the only factor found to adversely influencing OS (HR=3.6; 95% CI: 1.1–12.2), chronic GVHD development was the only favourably influencing PFS and relapse ratios (HR=0.3; 95% CI: 0.1–0.7 and HR=0.2; 95% CI: 0.1–0.6, respectively). TRM was adversely influenced by male sex of pt (HR=9.2; 95% CI: 1.5–66.6). Conclusions: RIT seems to be an effective treatment in MDS pts irrespective of conditioning type. While acute III/IV grade GVHD appeared to be detrimental, the benefit effect of chronic GVHD was to be bound to GVL effect. New approaches with focus on immunosuppressive treatment are needed to enhance the GVL effect with an acceptable risk of GVHD. No significant financial relationships to disclose.

Abstract We evaluated in a prospective pilot- study the effect of reduced intensity conditioning with busulfan (10 mg/kg), fludarabine (150 mg/m²) and anti-thymocyte globulin followed by allogeneic stem cell transplantation from related and unrelated donors in 14 patients with myelofibrosis. Study objectives were engraftment, chimerism, treatment- related mortality (TRM) and response. The median age of the patients was 51 (range, 32 – 63) years. According the Lille score there were low risk (n=4), intermediare risk (n= 7) and high risk (n=3) The median time until leukocyte (> 1.0 x 109/l) and platelet (> 20 x 109/l) engraftment was 16 (range, 11 – 26) days and 26 (range, 9 – 139) days, respectively. No graft failure occurred. Complete donor chimerism on day 100 was seen in 13 patients (93%). Acute graft-versus host disease (GvHD) grade II-IV occurred in 50% and grade III/IV 29 % of the patients. The incidence of chronic GvHD was 54 %. Two patients died due to treatment complications, resulting in a TRM at one year of 15% (95% CI: 0–35%). Hematological response after allogeneic transplantation was seen in all patients and complete histopathological remission was observed in 90%of patients. After a median follow-up of 13 (range, 3 – 48) months, the 3-years estimated overall and disease-free survival is 85 % (95 % CI: 65–100 %).

Abstract BACKGROUND: Graft-versus-host disease (GVHD) is the major obstacle to successful allogeneic stem cell transplantation (SCT) transplantation. Cyclosporine (Csa) in combination with methotrexate (MTX) is the most commonly used prophylactic regimen. The combination of CsA and Mycophenolate Mofetil (MMF) has recently been introduced. In this case-match study we retrospectively analyzed the introduction of MMF as GVHD prophylaxis in comparison with a short course of MTX in the setting of reduced intensity conditioning allogeneic SCT (Alo-RIC). PATIENTS AND METHODS: We analyzed 59 Alo-RIC recipients who received an Alo-HSCT from an HLA-identical sibling between April 2000 and June 2006. The median follow-up for the whole group was 473 days (8 to 2139 days). The study group included 40 males and 19 females. Median age was 59 years (range 43 to 72). Diagnoses were acute leukemia/myelodisplastic syndrome) (n=19/22), mutiple myeloma (n= 6), chronic myeloid leukemia (n=5) and non- Hodgkin lymphoma (NHL) (n= 4). GVHD prophylaxis consisted of Csa/MTX (MTX group) in 37 patients and Csa/MMF (MMF group) in 22 patients. The conditioning regimen was based on fludarabine in combination with busulfan (42 recipients) or melfalan (17 cases). RESULTS: The occurrence of mucositis grade 2–4 was higher in the MTX group than in the MMF group (62% vs 28% p= 0.015). No significant differences were found between MMF vs MTX groups in time to neutrophil recovery (16 +/−3 days vs 15 +/− 2days) (p= 0.5). Median time to the achievement of complete T-cell donor chimerism in the MTX and MMF groups was 79 days (range 19–740) and 76 days (range 24–223) respectively (P=0.4). The 1- year non-relapse mortality was similar in MTX and MMF groups 14% (95% C.L. 6–31%) vs 28% (95% C.L. 13–60%) respectively; P=0.2. Cumulate incidence of acute GVHD for MTX and MMF groups was 49% (95% C.L. 35–68%) and 68% (95% C.L. 51–91%) respectively (P= 0.6). Patients in the MTX group showed a trend to a higher incidence of chronic GVHD than the Csa/MMF group, 55% (95% C.L. 40–74%) vs 42% (95% C.L. 23–75%) (P=0.2). No differences were found between MTX vs MMF groups in 1-year overall survival [78%(64–92%) vs 53%(38–76%); P=0.1] nor in 1-year relapse incidence [37% (95%CI 21–64%) vs 19% (95%CI 10–37%) P=0.1) We conclude that the Csa/MMF combination appears to be equivalent to the standard Csa/MTX aGVHD prophylaxis in Alo-RIC. MMF showed significantly less mucositis.

Abstract Background: In vivo T-cell depletion with Alemtuzumab reduces the incidence of acute and chronic graft-versus-host disease (GvHD) and graft failure, yet it results in an increase of opportunistic infections and delayed immune recovery. In addition, Alemtuzumab has considerable anti-lymphoma activity in T-cell neoplasms. We report on a pilot study analysing the safety and feasibility of Alemtuzumab as pre-conditioning prior to reduced intensity conditioning allogeneic stem cell transplantation (RIC-alloSCT) in patients diagnosed with T-cell non-Hodgkin lymphoma. Methods: Six consecutive patients diagnosed with a T-cell lymphoid malignancy underwent RIC-alloSCT from a HLA-identical sibling (n=5) or a matched unrelated donor (n=1). Diagnosis were Angioimmunoblastic T-cell lymphoma (n=3), hepato-splenic gamma-delta T-cell lymphoma (n=1), T/NK cavum lymphoma (n=2) and Sèzary Syndrome (n=1). All received unmanipulated peripheral blood stem cells; At transplantation 2 patients were in CR, and 4 in PR. Median number of prior regimens was 2 (range 2-5). Conditioning regimen included Fludarabine (5 x 30mg/m2) and Melphalan (2 x 70mg/m2) in all cases. GvHD prophylaxis comprised Cyclosporine A and Methotrexate. The pre-conditioning protocol consisted on 6 escalating doses of intravenous Alemtuzumab starting on day -28 (3 mg on day -28, 10 mg on day -26 followed by four doses of 30 mg on days -24 to -17) given 3 times a week (MWF) on an out-patient basis. Results: Five patients received all six doses of Alemtuzumab as planned whereas one patient received only four doses for logistic reasons related to donor availability. Acetaminophen, Hydrocortisone and Dexchlorpheniramine were administered as pre-medication in all cases with no severe infusional reaction observed. There were no delays in proceeding to SCT conditioning and patients develop no infectious complications during the Alemtuzumab - alloSCT interval. All patients engrafted with a median time to neutrophil engraftment of 23 days (range 14-27). Acute skin GvHD (grade I and III) was observed in 2 patients (33.3%), both obtaining a CR with topical and systemic corticosteroids respectively. Two patients developed mild ocular chronic GvHD (one after subsequent infusions of donor lymphocytes - DLI) but none has suffered from extensive chronic GvHD. No opportunistic infection was observed apart from CMV reactivation that developed in 3 out of 4 seropositive patients (no CMV disease was observed). All patients experienced delayed immune reconstitution (CD4 >200/ul) at a median of 321 days (range 229-518). All 4 patients in PR prior to alloSCT achieved a complete remission. Only one patient (diagnosed with Sèzary Syndrome) experienced a relapsed and responded to DLI. With a median follow-up of 42 months, all patients remain alive and in CR. Conclusions: Our preliminary results suggest that administration of Alemtuzumab prior to reduced intensity conditioning is feasible and safe. In addition to providing T-cell depletion, Alemtuzumab may improve the response rate in T-cell lymphoid malignancies without increasing the risk of infectious complications. These results require further validation in larger phase II studies. Figure 1 Figure 1. Disclosures No relevant conflicts of interest to declare.

Abstract Allogeneic stem cell transplantation represents a potentially curative treatment modality for patients with advanced hematologic malignancies. However, the toxicity associated with fully myeloablative conditioning regimens has historically limited its use to younger, otherwise healthy patients. To investigate the feasibility of allogeneic stem cell transplantation in older (over 55 years) or otherwise higher risk patients (eg, prior transplant) with fully HLA-matched sibling donors, a reduced intensity conditioning regimen consisting of fludarabine (30 mg/M2 IV qd X 6, day −8 to −3), ATGAM 10 mg/kg IV qod X 4, day −7/−5/−3/−1) and melphalan (100 mg/M2 IV X 1, day −2) was employed in a single institution setting. GVHD prophylaxis consisted of cyclosporine (2 mg/kg IV bid, adjusted, beginning day −1) and methotrexate (10 mg/m2 IV, day +1/+3/+6). RESULTS: 21 patients with a variety of hematologic malignancies (AML=4, MDS=5, NHL=5, CML/MPD=3, HD=2, MM=1, CLL=1) were enrolled. Mean age was 54 years (range 28–66). 7 patients had undergone prior autologous transplants. Median followup among surviving patients was 42 months (range 3–58 months). Peripheral blood chimerism at day +100 was >95% donor in 16/18 patients, 80% (with subsequent conversion to 95%) in one patient, and >95% recipient (with documented relapse) in one patient. Acute GVHD grade 1–2 was seen in 52% and grade 3–4 in 10% of patients. Chronic GVHD was observed in 9/20 evaluable patients (45%). Infectious complications included documented bacteremia (6 cases), candida albicans fungemia (1), aspergillus pneumonitis (3), nocardia pneumonitis (2), CMV viremia (6), CMV colitis (1). Veno-occlusive disease (self-limited, grade 1–2) was observed in 4/21 patients (19%). Relapse was observed in 5/21 patients (24%) at a median 249 days post-transplant (range 97–328 days). Event-free survival was 90% (19/21) at 100 days, 58% (11/19) at 1 year and 47% (8/17) at 3 years. Overall survival was 95% (20/21) at 100 days, 68% (13/19) at 1 year and 47% (8/17) at 3 years. Primary causes of death were relapse (4/9), infection (4/9), and idiopathic pneumonitis/multi-organ failure (1/9). Chronic GVHD was a significant contributing factor in 3/4 fatal infections. PTLD was observed in one patient, who subsequently died of CMV infection/sepsis syndrome. CONCLUSIONS. Allogeneic BM/SCT using a reduced intensity conditioning regimen is feasible among older patients, and those who are otherwise poor candidates for myeloablative BM/SCT regimens; however, GVHD, infection, and relapse remain formidable obstacles to achieving successful outcomes.

AbstractWe evaluated the feasibility and efficacy of a reduced-intensity conditioning (RIC) regimen of fludarabine and melphalan to achieve rapid complete donor chimerism after allogeneic stem cell transplantation (SCT) in patients with metastatic solid tumors. Between January 1999 and January 2003, 8 patients with metastatic breast cancer (BC) and 15 with metastatic renal cell carcinoma (RCC) underwent allogeneic SCT after an RIC regimen of 5 days of fludarabine and 2 days of melphalan. Filgrastim-mobilized stem cells from HLA-identical related or unrelated donors were infused. Prophylaxis for graft-versus-host disease (GVHD) consisted of tacrolimus and methotrexate. All 22 evaluable patients had 100% donor chimerism at day 30 and at all measurement times thereafter. One patient died 19 days after SCT. Nine patients (39%) had grades II to IV acute GVHD and 10 patients (43%) had chronic GVHD. Five patients (22%) died of nonrelapse treatment-related complications. Treatment-related disease response was seen in 10 patients (45%), with 3 complete responses, 2 partial responses, and 5 minor responses. Fludarabine-melphalan is a feasible and effective RIC regimen for allogeneic SCT in metastatic BC and RCC. It induces rapid complete donor chimerism without the need for donor lymphocyte infusion. Tumor regression associated with GVHD is consistent with graft-versus-tumor effect. (Blood. 2003;102:3829-3836)
