Abstract
Gastrointestinal (GI) graft-versus-host disease (GVHD) is one of the most common causes of morbidity and mortality after allogeneic stem cell transplantation. In addition, cytomegalovirus (CMV) infection of the gastrointestinal tract can complicate the post-transplantation course of these patients and it can be difficult to differentiate the 2 diagnoses given that they can present with similar symptoms. We retrospectively analyzed 252 patients who were diagnosed with GI GVHD to evaluate the incidence, risk factors, and outcomes of CMV viremia and CMV gastroenteritis in these patients. The median age at the time of transplantation was 51 years, 35% were related donor transplantations, and 65% were unrelated donor transplantations. A total of 114 (45%) patients developed CMV viremia at a median of 34 days (range, 14 to 236 days) after transplantation. Only recipient CMV IgG serostatus was significantly associated with development of CMV viremia (P < .001). The incidence of CMV viremia with relation to donor (D) and recipient (R) CMV serostatus subgroups was as follows: D+/R+, 73%; D-/R+, 67%; D+/R-, 19%; and D-/R-, 0. A total of 31 patients were diagnosed with a biopsy-proven CMV gastroenteritis; 2 patients had evidence of CMV gastroenteritis and GVHD on the first biopsy and 29 on the second biopsy. Median time to development of CMV gastroenteritis was 52 days (range, 19 to 236 days) after transplantation. Using death as a competing risk, the cumulative incidence of CMV gastroenteritis at 1 year was 16.4%. The incidence of CMV gastroenteritis in relation to the donor/recipient serostatus was as follows: D+/R+, 22%; D-/R+, 31%; D+/R-, 12%; and D-/R-, 0. Median follow-up time for the 252 patients was 35.4 (95% CI 23.8 to 44.8) months. The estimated overall survival rate at 1 and 2 years was .45 (95% confidence interval [CI], .39 to .52) and .39 (95% CI, .33 to .46), respectively. Of the examined variables, those related to the overall survival were maximal clinical GVHD grade (P < .001) and development of CMV gastroenteritis (P = .008). Development of CMV viremia was not associated with increased mortality. In conclusion, CMV gastroenteritis is common complication in patients with GI GVHD and can adversely affect the prognosis.

Abstract
We performed a retrospective analysis of the outcome of 197 consecutive unrelated donor transplant recipients who received GVHD prophylaxis either TM regimen (tacrolimus and mycophenolate) (121 patients) or TM/ATG-G regimen (TM with low-dose antithymocyte globulin (ATG) of 4.5 mg/kg, ATG-G, Genzyme) (76 patients). Cumulative incidences of grade II-IV acute GVHD for the TM and TM/ATG-G cohorts were 49% and 61% (P=0.11) and grade III-IV acute GVHD for the TM and TM/ATG-G cohorts were 27% and 14% (P=0.02), respectively. There was no difference in the incidence of relapse or disease progression between TM and TM/ATG-G-16% and 23% (P=0.64). TM/ATG-G cohort had lower incidence of non-relapse mortality (NRM; 37% vs 20%, P=0.01), chronic GVHD (56% vs 43%, P<0.001) and more favorable global chronic GVHD severity (P<0.001). Univariate analyses showed improved OS and PFS of patients who received TM/ATG-G. Multivariate analysis confirmed TM/ATG-G had a favorable influence on OS (P=0.05) but not on PFS (P=0.07). We concluded that low-dose ATG of 4.5 mg/kg given in conjunction with TM improved GVHD prophylaxis without increased risk of relapse. Lower NRM, lower incidence and severity of chronic GVHD could potentially improve survival.

Abstract
Both acute and chronic graft-versus-host disease (GVHD) are major causes of morbidity and mortality in patients undergoing allogeneic hematopoietic stem cell transplantation (AHSCT). The optimal pharmacological regimen for GVHD prophylaxis is unclear, but combinations of a calcineurin inhibitor (cyclosporin or tacrolimus [Tac]) and an antimetabolite (methotrexate or mycophenolate mofetil [MMF]) are typically used. We retrospectively evaluated the clinical outcomes of 414 consecutive patients who underwent AHSCT from sibling (SD) or unrelated donors (UD) with Tac/MMF combination, between January 2005 and August 2010. The median follow-up was 60 months. Less than one third of the patients received a reduced-intensity chemoregimen. The incidence of grades III and IV acute GVHD was 22.3% and 36.5% in SD and UD groups, respectively (P = .0007). The incidence of chronic GVHD was 47.1% and 52.7% in the SD and UD groups, respectively. Nonrelapse mortality (NRM) at 60 months was 33.3% and 46.5% in the SD and UD groups, respectively (P = .0016). The incidence of relapse was 22.4% for UD and 28.8% for SD. Five-year overall survival was 43% and 34% in the SD and UD groups, respectively (P = .0183). GVHD was the leading cause of death for the entire cohort. Multivariable analysis showed that 8/8 HLA match, patient's age < 60, and low-risk disease were associated with better survival. The use of Tac/MMF for GVHD prophylaxis was associated with a relatively high incidence of severe acute GVHD and NRM in AHSCT from sibling and unrelated donors.

Abstract
We report our experience of collecting stem cells in patients who failed to mobilize sufficient hematopoietic stem cell (HSC) using plerixafor (P) in the initial mobilization attempt. Twenty four patients were identified who failed a first mobilization attempt using P. Of these, 22 patients received granulocyte colony stimulating factor (G-CSF) and two patients received cyclophosphamide (CY) + G-CSF in combination with P for the initial attempt. The agents used for second collection attempt were granulocyte macrophage colony stimulating factor (GM-CSF) + G-CSF (19 patients), G-CSF + P (three patients), CY + G-CSF (one patient), and bone marrow harvest (one patient). A median of 0.6 × 10(6) CD34(+) cells/kg (range 0-1.97) were collected in the initial attempt. A second collection was attempted at a median of 22 days (range 15-127) after the first failed mobilization. The median CD34(+) cell dose collected with the second attempt was 1.1 × 10(6) CD34(+) cells/kg (range 0-7.2). A third collection was attempted in six patients at median of 51 days (range 34-163) after the first failed mobilization. These patients collected a median of 1.1 × 10(6) CD34(+) cells/kg (range 0-6.5). Total of 16 patients (67%) collected sufficient cells to undergo autologous stem cell transplant and eight patients (33%) were able to collect ≥2 × 10(6) CD34(+) cells/kg in a single subsequent attempt. Our experience suggests that a majority of patients who fail primary mobilization despite use of P can collect sufficient HSC with a subsequent attempt using combination of G-CSF with either P or GM-CSF.

Abstract
INTRODUCTION Lenalidomide (LEN) is a relatively new and very effective therapy for multiple myeloma (MM). Prior LEN therapy is associated with an increased risk of peripheral blood stem cell collection (PBSC) failure, particularly with filgrastim (G-CSF) alone. We performed a retrospective chart review of 319 consecutive MM patients who underwent apheresis to collect PBSCs for the first autologous stem cell transplant (ASCT). RESULTS The median number of PBSCs collected in the LEN (+) group was significantly less than the LEN (-) group (6.34 vs. 7.52 × 10(6) CD34(+) cells/kg; p = 0.0004). In addition, the median number of apheresis sessions required for adequate PBSCs collection were significantly more in the LEN (+) group as compared to LEN (-) group (2 vs. 1 sessions; p = 0.002). In the LEN (+) group, there was a negative correlation between PBSCs collected and prior number of cycles of LEN (p = 0.0001). Rate of PBSC collection failure was 9% in the LEN (+) group and 5% in the LEN (-) group (p = 0.16). Only six patients who failed PBSC collection with G-CSF were able to collect adequate PBSCs with G-CSF + plerixafor. LEN exposure had no effect on neutrophil or platelet recovery post-ASCT. CONCLUSIONS Up to four cycles of LEN exposure have minimal negative impact on PBSC collection. Despite prolong exposure of LEN, PBSC collection was adequate for two ASCTs in the majority of patients and post-ASCT engraftment was not longer than expected; however, clinical relevance (complication rate, quality of life, cost) of prolonged LEN exposure on both PBSC and ASCT, should be evaluated in prospective clinical trials.

Abstract
A phase I trial of infusing anti-CD3 × anti-CD20 bispecific antibody (CD20Bi) armed activated T cells (aATC) was conducted in high-risk/refractory non-Hodgkin's lymphoma patients to determine whether aATC infusions are safe, affect immune recovery, and induce an antilymphoma effect. Ex vivo expanded ATC from 12 patients were armed with anti-CD20 bispecific antibody, cryopreserved, and infused after autologous stem cell transplantation (SCT). Patients underwent SCT after high-dose chemotherapy, and aATC infusions were started on day +4. The patients received 1 infusion of aATC per week for 4 weeks after SCT with doses of 5, 10, 15, and 20 × 10(9). aATC infusions were safe and did not impair engraftment. The major side effects were chills, fever, hypotension, and fatigue. The mean number of IFN-γ Enzyme-linked Immunosorbent Spots (ElSpots) directed at CD20 positive lymphoma cells (DAUDI, P = .0098) and natural killer cell targets (K562, P < .0051) and the mean specific cytotoxicity directed at DAUDI (P = .037) and K562 (P = .002) from pre-SCT to post-SCT were significantly higher. The increase in IFN-γ EliSpots from pre-SCT to post-SCT in patients who received armed ATC after SCT were significantly higher than those in patients who received SCT alone (P = .02). Serum IL-7, IL-15, Macrophage inflammatory protein (MIP)-1 beta, IP-10, MIP-1α, and Monokine induced by gamma interferone increased within hours after infusion. Polyclonal and specific antibodies were near normal 3 months after SCT. aATC infusions were safe and increased innate and specific antilymphoma cell immunity without impairing antibody recovery after SCT.

Abstract
We report the long-term follow up of 49 patients (pts) enrolled on plerixafor compassionate use protocol. Thirty-seven pts (76%) had failed one previous mobilization attempt, while 12 (24%) had failed two or more previous attempts. Using the combination of plerixafor and granulocyte colony-stimulating factor, we collected2.5 × 10(6) CD34+cells/kg in 33 pts (67%). Forty-three of the 49 pts proceeded to an auto-SCT (ASCT). The median days to WBC and platelet engraftment were 11 (range, 9-13 days) and 16 (range, 11-77 days) days post ASCT, respectively. The median WBC count, Hb and platelet counts 1 year after ASCT were 4.7 × 10(9)/L, 12.2 g/dL and 109 × 10(9)/L, respectively. With median follow up of 42 months (range <1-54 months), 21 pts had evidence of disease progression. Five pts developed myelodysplastic syndrome (MDS)/AML at median of 29 months post ASCT. The cumulative incidence of MDS/AML at 42 months was 17% (95% confidence interval, 6 to 32%). Development of secondary MDS/AML in pts proceeding to ASCT after plerixafor mobilization needs to be studied further in a larger cohort.

Abstract
This is a phase II trial evaluating efficacy and safety of aprepitant (AP) in combination with 5-HT3 antagonist and adjusted dose dexamethasone in patients receiving high-dose cyclophosphamide (CY) and filgrastim for stem cell mobilization. We used Simon's optimal two-stage design constrained to fewer than 40 patients with 10% type I error and 85% statistical power. The first stage of the study required accrual of 18 response-evaluable patients. The primary endpoint was the control of vomiting without the use of any rescue anti-emetics at 24 h after the administration of high dose CY (4 g/m(2)). If emesis was controlled in ≥9 patients, an additional cohort of 17 patients would be enrolled. The null hypothesis would be rejected if there were ≥20 responses among 35 patients. Forty patients were enrolled, five of whom were not evaluable for response. Eighteen evaluable patients were enrolled in the first stage. Acute emesis was controlled in 10 patients; therefore, enrollment proceeded to stage 2. An additional 17 patients were enrolled; 20/35 response-evaluable patients (57%) did not develop acute vomiting or require rescue anti-emetics, thus achieving the goal of the study. A total of 22/35 response-evaluable patients (63%) met the secondary endpoint of delayed emesis control (days 2-5). Thirty-three out of 35 patients underwent successful stem cell mobilization. No ≥ grade 3 AP-related adverse events were noted. The AP regimen can effectively control acute and delayed emesis in the majority patients receiving high-dose CY.

Abstract
Melphalan 200 mg/m(2) is the standard conditioning regimen for patients with multiple myeloma (MM) with normal renal function (NRF) undergoing autologous stem cell transplant (ASCT). In an effort to escalate the dose of melphalan and to improve the efficacy, we designed a dose-escalation study of melphalan in conjunction with palifermin in patients with NRF, with the hope that a higher dose of melphalan can be administered with an acceptable degree of oral mucositis (OM). We enrolled 19 patients (18 evaluable) with NRF. Dose-escalation of melphalan administered on day -2 began at 200 mg/m(2) with palifermin administered at a fixed dose of 60 mcg/kg/day. Palifermin was given as an i.v. bolus on day -5, -4, and -3, and then on day +1, +2, and +3. Subsequent dose escalations of melphalan were done at 20 mg/m(2) increments up to a maximum dose of 280 mg/m(2). Of 18 evaluable patients, there were no treatment-related deaths by day 100. The median age was 48.5 years (range, 33-65 years). The most common adverse events related to palifermin included rash (18 events, no ≥ grade 3 events), elevation of amylase (10 events, 4 were grade 3 but asymptomatic), and lipase (5 events, 2 were grade 3 but asymptomatic), edema (11 events, no ≥ grade 3). The overall incidence of OM grade 3 was 44% (8/18) with a median duration of severe mucositis of 5 days (range, 3-6 days). Eleven patients (61%) required opioid analgesics. None of the patients received total parenteral nutrition (TPN)/nasogastric feeding. Two of 6 patients who were given melphalan 280 mg/m(2) did not develop OM. Cardiac dose-limiting toxicity (DLT) in the form of atrial fibrillation did occur in 1 of 6 patients treated with melphalan 280 mg/m(2). Palifermin has permitted safe dose escalation of melphalan up to 280 mg/m(2), thus reaching the cumulative dosage of melphalan administered in tandem ASCT. This higher dose of melphalan has the potential to improve the efficacy and, hopefully, outcomes of patients with MM with a single ASCT. A phase 2 trial is necessary to better delineate the antimyeloma efficacy of this regimen.

Abstract
Transplantation-related mortality (TRM) is high after HLA-mismatched umbilical cord blood (UCB) transplantation (UCBT). In utero, exposure to noninherited maternal antigen (NIMA) is recognized by the fetus, which induces T regulator cells to that haplotype. It is plausible that UCBTs in which recipients are matched to donor NIMAs may alleviate some of the excess mortality associated with this treatment. To explore this concept, we used marginal matched-pair Cox regression analysis to compare outcomes in 48 NIMA-matched UCBTs (ie, the NIMA of the donor UCB unit matched to the patient) and in 116 non-NIMA-matched UCBTs. All patients had a hematologic malignancy and received a single UCB unit. Cases and controls were matched on age, disease, disease status, transplantation-conditioning regimen, HLA match, and infused cell dose. TRM was lower after NIMA-matched UCBTs compared with NIMA-mismatched UCBTs (relative risk, 0.48; P = .05; 18% versus 32% at 5 years posttransplantation). Consequently, overall survival was higher after NIMA-matched UCBT. The 5-year probability of overall survival was 55% after NIMA-matched UCBTs versus 38% after NIMA-mismatched UCBTs (P = .04). When faced with the choice of multiple HLA-mismatched UCB units containing adequate cell doses, selecting an NIMA-matched UCB unit may improve survival after mismatched UCBT.

Abstract
Acute graft-versus-host disease (aGVHD) is a major cause of morbidity and mortality in patients undergoing unrelated hematopoietic stem cell transplantation. We prospectively evaluated the efficacy of intermediate-dose rabbit anti-thymocyte globulin (Thymoglobulin® a total of 4.5 mg/kg given over days -3, -2, and -1) in combination with tacrolimus and sirolimus for the prevention of aGVHD. We enrolled 47 recipients who underwent unrelated hematopoietic stem cell transplantation. Patients received daily granulocyte colony-stimulating factor starting on day +6 until neutrophil engraftment (median duration, 11 days; range, 9-15 days). Twenty-two patients received HLA 8/8 and 25 received 7/8 matched grafts, respectively. The median follow-up duration was 23.6 months (range, 18.8-27.9 months). The cumulative incidence of grade II to IV aGVHD was 23.4% (95% confidence interval, 12.4-36.3). At 2-year follow-up, the cumulative incidence of nonrelapse mortality was 31.9%, cumulative incidence of relapse was 24.6%, and cumulative incidence of chronic GVHD was 33%. Progression-free survival at 1 year was 54%, with a median of 17.7 months. Overall survival at 1 year was 65%, with no median reached. These results suggest that the combination of Thymoglobulin, tacrolimus, and sirolimus in patients undergoing unrelated hematopoietic stem cell transplantation is well tolerated and associated with a low incidence and severity of aGVHD and chronic graft-versus-host disease.

Abstract
We enrolled 15 patients in this phase I dose de-escalation trial. Twelve patients are evaluable. The primary objective was to determine the safest and best tolerated maintenance dosing (MD) of bortezomib (B). The secondary endpoints were to evaluate complete response (CR), overall response (OR) and response duration. All patients receiving autologous stem cell transplant (ASCT) were eligible and registered between D+30 to D+120 after ASCT. A maximum number of 8 cycles of B was planned. Two evaluable patients in level (L) 1 received therapeutic dose of B 1.3 mg/m(2) intravenously on days (D) 1, 4, 8, and 11 in a 21 day cycle. Both these patients experienced dose limiting toxicities (DLTs). Four evaluable patients were then enrolled in dose L2 utilizing B 1.3 mg/m(2) on D 1, 4, 8, and 11 in a 28 day cycle. Two patients in L2 developed DLTs. Six evaluable patients were thereafter enrolled in L3 utilizing B 1 mg/m(2) on D 1, 8, and 15 in a 28 day cycle. Median 8 cycles of B were administered (2-8). No DLTs were observed in L3. The median duration of follow up for the entire cohort is 33 months (12-62). The median duration of response in L3 is 29.1 months (12-33). We conclude that B 1 mg/m(2) administered intravenously and may be subcutaneously on D 1, 8, and 15 in a 28 day cycle is the best tolerated MD and can be safely given beginning around D+100 post-ASCT.

Abstract
6549 Background: Autologous stem cell transplant (ASCT) remains part of standard therapy for Multiple Myeloma (MM). Lenalidomide (LEN) is a newer, effective therapy for MM. It has been suggested that prior LEN therapy is associated with an increased risk of stem cell collection failure, particularly when only G-CSF is used for mobilization. Methods: We conducted a retrospective chart review of 310 consecutive MM pts who underwent pheresis to collect stem cells for first ASCT between July 1, 2007 and June 30, 2011 at the Karmanos Cancer Institute. We compared differences in quantity of CD34 cells collected, days needed to collect the target number of cells (> 2.5 x 10*6 CD34+ cells/kg), days to platelet and neutrophil engraftment. We also evaluated the association between CD34+ cells collected and the number of cycles of LEN therapy. Results: Of 310 patients, 90% were mobilized with only G-CSF initially. Patients were analyzed as two groups: LEN exposed (LEN(+); n = 128) and LEN naive(LEN(-); n = 182). Median age in both groups was 58 years. No differences in race, sex and MM stage distribution were observed between the two groups. The median number of stem cells collected in the LEN(+) group was significantly less than the LEN(-) group (6.46 vs. 7.56 x 10*6 CD34 cells/kg; p= 0.0004). In addition, the median number of pheresis sessions required for adequate stem cell collection were significantly more in the LEN(+)group as compared to LEN(-) group (2 vs.1 sessions; p=0.002). In the LEN(+) group, there was a negative correlation between CD34+ cells collected and the prior number of cycles of LEN (p=0.0001). There was no statistically significant excess in the number of stem cell collection failures with G-CSF in the LEN(+) group (7% vs. 4% p=0.31). All pts who failed collection after G-CSF were successfully collected with Cytoxan or Plerixafor priming. LEN exposure had no effect on post-ASCT neutrophil or platelet recovery. Conclusions: Although Lenalidomide exposure is associated with a slightly lower CD34+ stem cell yield and on average an extra session of pheresis when G-CSF is used for mobilization, collection failure is uncommon and post-ASCT engraftment is normal.

Abstract
UNLABELLED High-dose melphalan 140 mg/m2 is the standard of care for patients with multiple myeloma (MM) with renal insufficiency (RI). Palifermin as a cytoprotective agent has demonstrated efficacy in reducing the intensity and duration of oral mucositis (OM) in patients who receive intensive chemotherapy/radiotherapy. There is no prospective data on the use of palifermin in patients with MM with RI. ELIGIBILITY CRITERIA creatinine clearance ≤60 mL/minute/1.73 m2, age >18 years, no dialysis, no active OM, and a suitable candidate for autologous stem cell transplant (ASCT). Melphalan dose ranged from 140 to 200 mg/m2 and escalated at the increment of 20 mg/m2. Six dosages of palifermin 60 mcg/kg/day were given intravenously between day -5 to day +3. Dose escalations were to stop if dose-limiting toxicities (DLTs) occurred at melphalan dose in ≥2 of 3 patients, with that dose declared as the maximal administered dose and the level below where ≤1 of 6 patients had DLTs was considered the maximally tolerated dose (MTD). Nineteen patients were enrolled from June 2007 to June 2011. Data on 15 evaluable patients is reported as 4 patients were removed. Median age was 59 years (range, 36-67 years). The overall incidence of OM ≥ grade 3 was 53% (8 of 15) and a median duration of ≥grade 3 OM was 6.5 days (range, 3-42 days). One patient in L2 (melphalan 160 mg/m2) developed atrial fibrillation on day +9. Two patients in L4 (melphalan 200 mg/m2) developed grade 4 OM, hence reaching DLT. No DLT was observed in 6 patients enrolled in L3 (melphalan 180 mg/m2). Palifermin has permitted safe dose escalation of melphalan up to 180 mg/m(2) in patients with RI.
