Abstract Introduction: Mantle cell lymphoma (MCL) often follows an aggressive course and remains incurable with standard therapies. First-line chemotherapy followed by consolidation with high-dose chemotherapy (HDT) and autologous stem cell transplant (ASCT) has become a standard of care in eligible patients (pts). As relapse remains the main cause of treatment failure, strategies such as intensifying induction therapy with high-dose cytarabine or adding rituximab maintenance (RM) have been tested to reduce the relapse rate (RR) post-ASCT. We evaluated the effect of the addition of cytarabine and RM on the outcome of pts undergoing ASCT. Methods: We conducted a retrospective analysis of consecutive MCL pts who underwent ASCT after first-line chemotherapy at the Princess Margaret Cancer Centre between 2000-2013. Pts received induction with CHOP, RCHOP, or RCHOP alternating with RDHAP (RCHOP/RDHAP), followed by HDT with or without total body irradiation (TBI). All pts had a documented response to induction using Cheson 1999 criteria. After ASCT, pts received maintenance with single-agent rituximab 375 mg/m2 or were simply observed. Results: 98 MCL pts were treated: median age was 56 years (36-66), 15 pts (15%) had blastoid or pleomorphic subtype, 85 pts (87%) had stage IV disease. MIPI was high risk in 18 pts (19%). Induction therapy: CHOP 14 pts (14%), RCHOP 57 (58%), and RCHOP/RDHAP 27 (28%). After induction CR was obtained in 44%, PR in 56% pts. CR rates were: CHOP 7 (50%), RCHOP 25 (44%), RCHOP/RDHAP 12 (44%) (P=ns). 89% pts had collected > 5*106 CD34/kg after RCHOP, and 78% after RCHOP/RDHAP (P=ns). Overall 66/98 pts (67%) had > 5*106 CD34/kg collected with 1 apheresis (Table 1). HDT was melphalan+etoposide for 63% pts, cytarabine+melphalan for 31% pts; 77 (79%) also received TBI. Median time from diagnosis to ASCT was 7.5 months (2.5, 33.4). Post-ASCT responses: CR 92 pts (94%), PR 4 (4%), 2 (2%) PD. Median time to ANC ≥0.5 were 10 days (CHOP), 11 days (RCHOP), and 11 days (RCHOP/RDHAP), while median days to PLT≥20 were 9 (CHOP), 11.5 (RCHOP), and 13 (RCHOP/RDHAP). Post-ASCT, 31% of pts had normal blood counts at 3 months which improved to 52% at 1 year post-ASCT. Maintenance data were available for 95/98 pts. RM was given to 72 pts (74%). Median follow-up from date of transplant for the entire cohort was 3.22 years (range 0.7 - 14.1). The 2-year and 5-year PFS were 85.8% (76.7-91.5) and 52.2% (37.7-64.7), respectively. 32 pts relapsed after ASCT (32.65%). Relapse occurred in 3 (11%) pts after RCHOP/RDHAP, 19 (33%) after RCHOP, and 10 (71%) after CHOP. Median time to relapse was 9 years (95%CI: 4.7-NR). 2-year and 5-year RR were 14.54% and 41.65%, respectively. Median OS was 9.15 years (95%CI: 7.3-NR), 2-year OS was 88.8% (80.2-93.8), and 5-year OS was 74.9% (61.7-84.2%). For patients observed without treatment post-ASCT, median PFS was 2.87 years (1.22-4.63) and median OS 5.19 years (1.66-NR), while for those receiving RM, PFS was 9.06 years (4.97-NR, p<0.001) and median OS has not yet been reached (7.30- NR, p=0.009). Conclusions: Response rate and PFS were similar between different induction regimens. The outcomes of responding pts following ASCT appear superior to previous strategies. Our patients enjoyed a very long PFS and median OS is surprisingly long as well. Within the limits of a retrospective study, our data support the use of rituximab maintenance, showing a significant benefit in both PFS and OS. Table 1.

Abstract Conventional chemotherapy is non-curative for mantle cell lymphoma (MCL). Although the addition of Rituxan has improved the outcome of these patients, many patients still relapsed and died of their disease. High dose chemotherapy followed by autologous stem cell transplant (ASCT) has been investigated but produced conflicting results, ranging from no demonstrable benefit to a 2-year event-free survival (EFS) of 77%. A recent randomized study compared ASCT with interferon-a maintenance and showed benefits in both the EFS and overall survival for patients in the ASCT study arm. The conflicting results are probably related to the use of different chemotherapeutic agents as conditioning regimens for the transplant and also to different post-transplant therapy. In this study, we have chosen to induce patients with advanced MCL with R-CHOP and consolidate these patients with high dose single agent melphalan, a cytotoxic that has not been previously tested as a single agent in MCL. Since most patients relapsed within the first two years after transplant, low dose maintenance Rituxan therapy is given three-monthly during the first 2 years after ASCT. Following consent from the patients, 8 consecutive patients with advanced Stage III or IV MCL were treated. There were 5 male and 3 female, with a median age of 642 years (range 46–72 years). One patient had Stage III and the other 7 Stage IV diseases. All eight patients received remission + 2 courses of R-CHOP as induction chemotherapy. Autologous stem cells were harvested upon recovery from the last course of R-CHOP and ASCT carried out within 6 weeks from the last course of R-CHOP. High dose intravenous melphalan (200 mg/m2) was administered followed, 24 hours afterward, by the infusion of a minimum of 2 × 106/kg of CD34+ autologous stem cells. Rituxan maintenance therapy was initiated at a dose of 375 mg/m2 given as a single infusion once every three months starting Day +100. As of August 2006, with a median follow-up of 45.5 months from diagnosis (range 10–57 months) and 39 months from ASCT (range 4–52 months), seven patients are alive lymphoma-free, as defined by clinical and PET-CT examination. One patient died in CR of a myocardial infarction. Adverse effects were as expected from the high dose melphalan, except that delayed immunoglobulin reconstitution, as reported previously, was observed in all eight patients. Four of these hypogammaglobulinemic patients had recurrent infections (three with recurrent respiratory tract infection and one with a chronic diarrhea that was Vancomycin sensitive) and two required monthly intravenous immunoglobulin replacement. The result presented here is, therefore, extremely encouraging for a group of patients who normally have a very poor clinical outcome and warrants confirmation in larger multicenter study.

Abstract Abstract 2395 While already tested in T-PLL, the impact of chemo-immunotherapy with alemtuzumab in combination with bi-weekly CHOP on autologous stem cell harvest (ASCH) has not yet been analysed in the context of first line treatment of primary systemic peripheral T-cell lymphoma (PTCL). We therefore evaluated the feasibility of ASCH in the first 23 patients of the ongoing international multicenter ACT-1 study, the first, and so far only, randomized trial in primary systemic PTCL. The ACT trials (ACT-1 + ACT-2) test the addition of alemtuzumab to CHOP followed, in younger patients (ACT-1), by high-dose therapy with autologous stem cell transplant (HDT+ASCT). The aims of the analysis were: (i) feasibility of ASCH in alemtuzumab + CHOP (A-CHOP) treated patients as compared to patients not receiving the antibody, but otherwise treated and managed in the same way, and (ii) comparison of ASCH counts in the two treatment arms. By July 2010, 20 patients, 11 in the standard treatment (arm A) and 9 in the experimental treatment (arm B) cohort, had undergone induction therapy and had been primed for subsequent ASCH according to local guidelines. Histological subtype distribution in the two treatment groups showed: PTCL not otherwise specified N=4 (arm A) and N=5 (arm B), angioimmunoblastic N=5 (arm A) and N=4 (arm B), extranodal NK/T-cell, nasal type N=1 (arm A), hepatosplenic N=1 (arm A). Pre-therapeutic evidence of bone marrow involvement was present in 4 (arm A) and 2 (arm B) patients, respectively. Of the original 23 patients, three did not undergo stem-cell harvest due to progressive disease (1 pt), patient's decision (1 pt), and pre-therapeutic CNS involvement (1 pt). Among the 20 harvested patients, ASCH failure was experienced in three patients (standard arm N=1 and experimental arm N=2; p=0.57). In two patients (one in each treatment cohort) a suboptimal stem cell yield could be optimized by the use of plerixafor according to local guidelines. A comparison of stem cell counts (CD34+ cells × 106/kg body weight) from the two treatment cohorts showed a trend towards moderately lower stem cell yields in alemtuzumab-treated patients (3.34 CD34+ cells × 106/kg body weight in arm B vs 6.54 CD34+ cells × 106/kg body weight in arm A, p=0.03). In conclusion, the addition of alemtuzumab to bi-weekly CHOP in the setting of first-line therapy of primary systemic PTCL does not significantly impair ASCH prior to upfront autologous stem cell transplant.

Abstract Abstract 4550 Background: High dose therapy with autologous stem cell transplant (SCT) is an established therapeutic modality for multiple myeloma (MM). Although effective, it is associated with significant symptom burden due to the obligate period of neutropenia in addition to an increased risk of infectious complications. In animal models, infusing stem cells over a period of days enhances immune reconstitution (Felfly H, et al. Br J Haematol. 2009; 148: 646–658). We hypothesized that multiple stem cell infusions could reduce the period of neutropenia and enhance immune recovery resulting in a better tolerated procedure. Methods: We are conducting a phase II trial of multiple fractionated autologous stem cell infusions after high-dose Melphalan. We compared initial engraftment kinetics of the first 14 patients to receive multiple infusions (Days 0, +2, +4, +6) after high-dose Melphalan (study group) to 23 patients receiving high-dose Melphalan followed by the standard single stem cell infusion (Day 0) (standard group). Pegfilgrastim was given to all patients on Day +1. All patients underwent SCT between October 2011 and July 2012. Results: Results are shown in Table 1. Similar numbers of stem cells were collected in the study and standard groups. The total number of stem cells infused was 9.7 × 10∧6 CD34+ cells/kg in the study patients compared to 5.0 × 10∧6 CD34+ cells/kg in the standard patients. To date, the median duration of neutropenia (days of ANC < 500) and lymphopenia (days of ALC < 500) as well as the days to neutrophil, lymphocyte and platelet engraftment are similar. There are no significant differences in the number of red cell or platelet transfusions, days of fever, diarrhea, empiric antibiotics or documented infections. Despite receiving multiple infusions, none of the patients in the study group experienced an infusion reaction. Engraftment syndrome occurred in 3/14 (21%) of the study patients. The median duration of hospitalization was 15 days in the study cohort versus 17 days in the concurrent control group (P = 0.01). Conclusion: Multiple stem cell infusions following high dose Melphalan in patients with MM were not associated with a higher incidence of adverse side effects from DMSO nor unexpected frequency of engraftment syndrome. Fractionating stem cells over a period of days may result in less antibiotic use, reduced frequency of infection and was associated with shorter hospitalizations. We continue to collect patient reported symptom scores in order to determine if we can improve patient experience during SCT. Disclosures: No relevant conflicts of interest to declare.

9011 Background: 131I-MIBG provides targeted radiotherapy with >30% response in refractory neuroblastoma, but the activity infused is limited by radiation safety and hematologic toxicity. The goal was to determine the maximum tolerated dose of 131I-MIBG in two consecutive infusions at a 2-week interval, supported by autologous stem cell transplant (ASCT) 2 weeks after the second dose. Methods: The 131I-MIBG was escalated in a 3+3 Phase I trial design, with levels calculated by total red marrow radiation index (RMI) from the double infusion. The first infusion of 131I-MIBG was 12, 15, 18 and 21 mCi/kg for levels 1, 2, 3 and 4 respectively. Using detailed dosimetry, the second infusion was adjusted to achieve the target RMI, except at Level 4, where the second infusion was capped at 21 mCi/kg. Results: Twenty-one patients were enrolled at Level 1–4, with 18 evaluable for toxicity. Median age at enrollment was 7 years, all were heavily pretreated, including 12 with prior high dose therapy and ASCT, and 12 patients had bone marrow tumor. Cumulative 131I-MIBG given to achieve the target RMI ranged from 18 mci/kg to 49 mCi/kg. RMI delivered per mCi of MIBG decreased in 15/19 patients by mean of 0.21 cGy/mCi with the second infusion. Hematologic toxicity was acceptable, with median time to ANC>500 after ASCT of 13 (4–27) days. Platelet transfusion was required in 15/18 patients, with median time to platelet independence of 18 (6–47) days after ASCT. There were no non-hematologic toxicities above grade 2 attributed to therapy, though 9 patients had grade 1–2 elevations of transaminase, and 1 had grade 2 hypothyroidism. Responses in 17 evaluable patients included 1 PR, 4 MR, 6 SD, and 6 PD. Eleven patients are alive at median of 361 days (46–483); 5 died of PD and 1 of unrelated toxicity. Conclusion: The lack of toxicity with this approach allowed dramatic dose intensification of 131I-MIBG, with minimal toxicity and the possibility of improved response.

Abstract Background: Treatment of AL amyloidosis with high dose intravenous melphalan followed by autologous stem cell transplant (HDM/SCT) is effective in inducing hematologic and clinical remissions associated with prolonged survival. The major toxicities are myelosuppression and GI side effects. Studies have shown that ~75% of melphalan in the blood is bound to plasma proteins, with ~25% free. We hypothesized that AL patients with severe nephrotic syndrome and profound hypoalbuminemia might have a higher fraction of free melphalan, a higher effective dose, and greater toxicity of treatment. Methods: Patients with AL amyloidosis and severe hypoalbuminemia, defined as serum albumin level of < 2 g/dL, treated from 2011 to 2013, were studied retrospectively. The stem cell transplant database was queried for dose of HDM, treatment-related complications, and days of neutrophil and platelet engraftment after SCT. Results: Of 71 patients with AL amyloidosis who underwent HDM/SCT between Jan 2011 and Dec 2013, 12 patients had severe hypoalbuminemia. Of these, 5 received full HDM at 200 mg/m2 and 7 received modified HDM at 140 mg/m2. All patients received GCSF mobilized peripheral blood stem cells following HDM, with a median stem cell dose of CD34+ cells 8.1 x 106/kg (range, 4.0 to 12.2). The median time to engraftment of neutrophils was 11 days, and not statistically different based upon melphalan dose. The median time to platelet engraftment was 13 days, and also did not differ significantly by dose. These times were similar to controls without severe hypoalbuminemia. Grade 4 toxicities were observed in 2 of 7 patients with modified HDM/SCT and 1 of 5 patients with full HDM/SCT. Conclusions: These data suggest that patients with severe hypoalbuminemia do not have more prolonged myelosuppression or increased non-hematologic toxicities compared to other patients. In this retrospective study, we did not measure free melphalan concentrations in the blood. However, these data suggest that patients with severe hypoalbuminemia do not require adjustment of melphalan dosing. Disclosures No relevant conflicts of interest to declare.
