Abstract Autologous Stem Cell Transplantation (ASCT); is a universal accepted therapy for rescuing relapsed Hodgkin (HL) and non-Hodgkin (NHL) lymphoma patients and for consolidation of mantle cell lymphoma (MCL). The most used preparative regimens in this setting are BEAM and CBV. both of them include carmustine, a medication with serious shortage and cost problems, therefore , is very important to find alternative regimens. During the nineties the combination of high dose of carboplatin plus cyclophosphamide and etoposide (CEC) was explored, however, it was abandoned due to high toxicity. We present our experience with 108 patients using this regimen but with intermediate dose of carboplatin (Inter CEC) Methods: We did a retrospective descriptive longitudinal observational study. All consecutive patients who met the inclusion criteria; age above 18 years, diagnosis of HL, NHL, M CL, and transplanted with Inter CEC were included. The preparative regimen consisted of carboplatin 900 mg/m2, etoposide 900 mg/m2, and cyclophosphamide 6.000 mg/m2, split in five days (fig 1). All patients received peripheral blood stem cells, and from d + 5 until neutrophil recovery, daily filgrastim. Every patient signed informed consent and the study was approved for institutional ethical committee. Results: From Oct 2013 to May 2020, 108 patients were included; median age was 45 years (18-70), 43.5% were female, 20% were older than 60 years and 79.6% had advanced disease at diagnosis. Thirty-five (32.4%) had HL, 35 (32.4 %) NHL (28 diffuse large B cell, 7 follicular), 29 (26,9%) had MCL, and 9 (8.3%) had other lymphomas. 34% of HL patients and 48% of cases were transplanted in CR1 after being refractory to first line therapy, while 44% and 14% of HL and NHL respectively had active disease at the time of transplantation. Regarding MCL cases; 21 (72,4%) had MIPI above 3 points and 96.5% were transplanted in first remission. All of the evaluable patients at day + 30 had hematopoietic recovery, median time to achieve 500 neutrophil /ul or more was 12.3 days (10-30) and for self-sustained platelet counts, 20.000/ul or more, was 15.3 (10-34). After a median follow up for surviving patients of 42,2 months the overall survival (OS) (Kaplan-Meier) at 48 months for the entire group was 74% (CI 63-82) and the event free survival (EFS) was 57% (CI 43-69). When the OS and EFS were discriminated for diseases, it was; for HL 76% (CI 56-88) and 43% (CI 17-66), for NHL 78% (CI: 57-90) and 68% (CI 42-83), and for MCL 69% (48-83) and 57% (CI 32-76) respectively (Fig 2). Eleven out of 18 patients (61%) transplanted with active disease achieved complete remission and 14 out of the entire group relapsed during the first years of transplant The transplant related mortality (TRM) at 1 year was 2.8%, the relapse associated deaths were 13% and, in 5 patients, who died after one year of transplant, the cause was not found. The main toxicity was mucositis; 46%, (grade II-IV: 22%), 30 patients (28%) had confirmed infections; bacteremia 17 cases, pneumonia 5, and others infections 6. Renal toxicity occurred in 24 cases (22%), grade 1; 15.8%, grade 2; 4.6% and grade 3; 1.8% Discussion Comparing results among trials is always difficult; however, despite that, in our series 58% of the cases were transplanted with active disease, our outcomes compare favorably with the results informed after the use of BEAM or CBV presented by CIBMTR in the largest trial published so far (table 1). The use of intermediate dose of carboplatin plus etoposide and cyclophosphamide produces a very good control of the lymphoma activity with acceptable toxicity, and achieves good OS and EFS. Other advantage of this regimen is that is carmustine free. The next step in our study is to do a matched paired analysis with patients transplanted with BEAM or CBV Figure 1 Figure 1.

Abstract Abstract 4046 Treatment with lenalidomide, an immunomodulatory drug, increases the time to progression in relapsed/refractory multiple myeloma. However, due to its pleiotropic effect, it is not known whether the efficacy of this drug is due only to direct tumor toxicity or also to immunomodulatory effects. We assessed in vivo the changes in T-cell reconstitution induced by lenalidomide consolidation and maintenance treatment following autologous peripheral blood stem cell transplantation (ASCT) in a cohort of multiple myeloma patients. Twenty-nine newly diagnosed myeloma patients were treated with the induction combination bortezomib plus dex followed by high dose melphalan (140–200 mg/m2) and ASCT. A first group of 11 patients were treated with lenalidomide consolidation initiated 3 to 6 months post transplantation: 25 mg/day, days 1–21 of a 28 day cycle for 2 months, followed by maintenance (10 mg/day) until disease progression. This group was compared with the 18 patients who did not receive any treatment after ASCT. Blood samples were collected at diagnosis, before the transplant and 1, 3, 6, 9, 12 and 18 months after ASCT. Thymic function was assessed by real-time PCR quantification of T cell receptor excision circles (sjTREC) and percentages and absolute counts of T lymphocyte subpopulations were determined by multicolor flow cytometry. Statistics were performed using the Log-Rank or Mann-Whitney test. The two cohorts had similar baseline characteristics and all 29 patients were in remission after ASCT. With a median follow-up of 4 years, progression-free survival (PFS) was superior with lenalidomide treatment (69% vs 36%, p=0.05) while overall survival (OS) was similar (82% vs 75%, p=0.5). Lenalidomide treatment induced a progressive decrease in sjTREC (median at 18 months, 0.25/μL vs 1.61/μL, p<0.05) and a decrease in the percentages and absolute counts of CD4+ and CD8+ CD45RA+CCR7- effector terminal T cell subpopulations (median at 18 months, 3.2/μL vs 17.6/μL, p<0.05 for CD4+CD45RA+CCR7- and 109/μL vs 345/μL, p<0.05 for CD8+CD45RA+CCR7-). Conversely, lenalidomide treated patients displayed an increase in CD4+CD25+CD127-/low Treg populations, in both percentage and absolute count (median 13% vs 8 %, p<0.05 and 48.9/μL vs 29.3/μL, p<0.05, respectively). No correlation was found with documented infections, relapse or survival. We confirm an increase in PFS with lenalidomide consolidation/maintenance following ASCT. However, our data also suggest that in myeloma patients, the effect of lenalidomide on the myeloma tumor may not be T cell mediated and this treatment may have a negative impact on the T cell immune surveillance.

Abstract Background: Melphalan 200mg/m2 is the standard preparative regimen in MM and addition of other cytotoxic drugs has not been found to result in superior activity. The novel agents have improved outcome in MM significantly, but data on their role in preparative regimens are scarce. The purpose of this study was to understand the toxicity and efficacy of triple therapy with VDT in combination with high-dose melphalan. Methods: An IRB approved retrospective analysis was performed on all patients who received an ASCT with the VDT-Mel during 2012-2014. Mel: 100 mg/m2 was given on days -4 and -1; V: 1 mg/m2 on days -4, -1, +2 and +5; T: 100 mg daily from -5 to +5; and D: 20 mg/day from -4 to -1 and +2 to +5. End points were treatment-related toxicity during the first 100 days and quality of response at 6 months post-transplant; 98 patients had follow-up ≥ 6 months. Patients in sCR were also minimal residual disease negative (MRD-) by 10-color flow cytometry with a sensitivity of 10-4. Results: 100 patients received 153 transplants; 47 patients underwent single and 53 had tandem transplants (TT); 64 patients received early (≤ 12 months of induction therapy) and 36 salvage transplantation. Median age was 61 y; median followup was 16.2 months. Only 1patient had achieved a sCR and 11 a CR prior to transplantation. Best responses at 6 months were 53% sCR (and MRD-), 24% CR, and 9% VGPR. The sCR rate after single transplant was 47% (overall) and 54% (early transplant) vs 59% and 60% after TT. Grade 3-5 non-hematologic toxicities were almost entirely related to infections (38% and 53% in single and TT, respectively); the 100-day mortality rate was 2.6% (4/153), 1.8% for early transplants and 4.5% for salvage transplants. Median time to ANC recovery > 500/µL was 12 days in both early and salvage transplantation. Conclusion: VDT-Mel is well-tolerated and resulted in minimal additional toxicity and a similar mortality rate when compared to historic data of MEL alone. Importantly, the sCR rate with MRD- by flow cytometry at 6 months in our study was very high compared to published reports. The ultimate sCR rate will be higher as at this time an additional 13 patients attained a sCR during further follow up past 6 months for a total of 66% sCR. Since both sCR and MRD- are proven early surrogate markers for progression-free and overall survival, it appears highly likely that this regimen will be superior to Mel alone and should become the new standard for ASCT in myeloma.

Abstract High-dose treosulfan followed by autologous transplantation is a tolerable and efficacious regimen in quite different tumor types. Aim of the present study was to proof safety and efficacy of high-dose treosulfan in an intraindividual comparison with melphalan. Between August 2003 and July 2006, 20 patients with multiple myeloma, age< 60 years were enrolled onto an unicentric phase II trial. The median age was 55 years. All patients received pretreatment with 3 to 4 cycles idarubicin and dexamethasone (90%) or CAD (10%). After induction the peripheral blood stem cells were mobilized with a combination of ifosfamide, epirubicin, etoposide (IEV) followed by G-CSF. Stem cell harvest was successful in all patients. Thereafter, the patients received tandem transplantation in an interval of 2 months, first after conditioning with high-dose treosulfan on day −4 to −2, 14g/m2 daily, then after high-dose melphalan 140 mg/m2. Maintenance therapy with interferon-alpha was administered in 30% of the cases. For all patients the completion rate of the first transplantation was 100%, for the second 85%. Three patients did not proceed to the second autologous transplantation due to a severe ischemic colitis (n= 1) or a high-risk profile (allogeneic transplantation in 2 cases). Two patients received an allogeneic transplantation during the further course of the disease. Overall the conditioning regimens were well tolerable. Hematotoxicity grade 4 was observed after each high-dose cycle. Grade 3/4 infections and stomatitis were present in 5%/5% after treosulfan and in 18%/6% after melphalan. An acute coronary heart syndrome occurred after Mel140. The duration of severe leukopenia (< 1.0 leukocytes) was significantly shorter after treosulfan (6.4 days vs. 7.9 days, p= 0.009), whereas time to leukocyte recovery did not significantly differ between the regimens. No treatment related deaths occurred. Best response after transplantation was CR 30%, PR 60%, NC 5%, and PD 5%. In comparison to the preceding chemotherapy a further >50% decline of the paraprotein was achieved by treosulfan in 3 cases, by melphalan in 2 cases. In the intraindividual comparison treosulfan and melphalan, respectively, have shown two times superior response. The median event-free survival was 28 months, and the overall survival at 4 years was 81%. In conclusion, high-dose treosulfan may be more favorable for patients at risk for infections than melphalan, and seems to be as efficacious as melphalan for the treatment of multiple myeloma. Treosulfan should be further investigated in multiple myeloma patients.

Abstract Abstract 2174 Introduction: The prognosis for patients with primary induction failure (PIF) or relapsed acute myeloid (Rel-AML) is poor. Mitoxantrone (M) plus etoposide (E)- based salvage regimens (ME), in particular, either alone or with intermediate dose cytarabine (MEC) are effective in these high risk patients; However, these regimens have not been directly compared. Heterogeneity in chemotherapy dose, dose escalation and age have been important limitations in the evaluation of previous studies. Also problematic, historically patients were classified according to FAB criteria. Since then, karyotype has been shown to be a main determinant of prognosis. The influence of karyotype on response to ME or MEC is currently unknown. Herein, we report the response to treatment with a fixed dosing schedule of ME or MEC in 66 patients treated for PIF or Rel-AML with intermediate(intermed-) or unfavorable(unfav-) risk cytogenetics. Differences in CR between ME and MEC subsets were analyzed to determine the effect of adding of C to ME. Methods: 66 consecutive patients with PIF or Rel-AML treated with either ME(n=37)or MEC(n=29) between 10/2004-12/2008 were evaluated. All patients had received initial induction therapy with daunorubicin 45–60mg/m2 IV bolus d1-3 and cytarabine 100mg/m2 CI d1-7(7+3), and consolidation with HIDAC if CR was achieved. ME and MEC were dosed according to previously published studies. The decision to use a given salvage was left to the discretion of the treating physician. Chi-Square test was used for statistical analysis. Results: Table1 shows there was no difference between the ME and MEC groups with regards to age, sex, % blasts at initial diagnosis, and %CR after initial induction with 7+3, or % patients who received inter- to high dose C prior to ME or MEC. Length of CR (after 7+ 3 and consolidation) was significantly longer in the MEC group. A significantly higher number of CR's was observed in the MEC group compared to ME(p=0.05). Within the MEC group, no difference in CR was observed between patients with intermed- and unfav-risk cytogenetics(p=0.96). The same was true within the ME group(p=0.13). When MEC was compared to ME, a significant difference in CR was observed in patients with unfav-risk cytogenetics(p=0.044) and patients <60years old. Prior to therapy, MEC patients had higher number of blasts. MEC patients had a significantly longer duration of remission. One patient in both the ME and MEC group died before hematopoetic reconstitution. Conclusion: In clinical practice, as observed in the present study, we observed a greater overall CR rate in patients who received MEC compared to those treated with ME, particularly in younger patients with unfav-risk cytogenetics. For those who achieved CR after MEC or ME, a longer duration of CR was observed in the MEC group compared to ME. These results could be particularly beneficial for those patients receiving salvage therapy as a temporizing measure prior to allogeneic hematopoetic stem cell transplant ion, and encourages confirmation from a prospective trial.

Abstract Background: Multiple sclerosis (MS) is a chronic, inflammatory, debilitating disease that causes destruction of central nervous system (CNS) myelin, with varying degrees of axonal damage. With the goalofd re-setting the immune system, autologous hematopoietic stem cell transplantations (HSCT) have been done in patients with MS since 1996 and more than 700 HSCTs have been performed around the world. The risk of transplant related mortality in HSCT for MS has declined over the past years. Material and methods: Consecutive patients with MS were autografted in a single center using: Hematopoietic stem cells (HSC) were mobilized with cyclophosphamide (Cy), 3 gr/m2 and G-CSF, the procedure was conducted on outpatient basis employing peripheral blood non-frozen HSC and conditioning with high-dose Cy (100 mg/Kg) and post-transplant G-CSF and rituximab. Antibiotics, antimycotics and antivirals were given orally. Results: Thirteen patients with MS were prospectively accrued in the study. There were 7 females and 6 males. Median age was 48 years, range 24 to 65. The expanded disability status scale (EDSS) score of these patients had a median of 5 points (range 1 to 6). All the autografts were started on an outpatient basis and two persons were admitted to the hospital during the procedure (persistent nausea/vomiting and neutropenic fever); they stayed in the hospital for 48 hours. In order to obtain a minimum of 1 x106 viable CD34+ cells/Kg, one to four apheresis were done (median 1). The total number of viable CD34+ cells infused to the patients ranged between 1 and 9.6x106 (median 3.1). Patients recovered above 0.5 x109/L absolute granulocytes on median day 9 (range 6 to 12). No individuals needed transfusions of red blood cells nor platelets transfusions. There were no transplant-related deaths and the 23-month overall survival of the autografted patients is 100%. Median cost of the procedure was 30 000 USD. In 8 persons the EDSS was assessed three months after the graft; it diminished from a median of 4.5 to a median of 2.5. In 5 patients, the three months re-assessment of the EDSS has not been possible as a result of the time elapsed after the autograft. Discussion: These data indicate that it is possible to conduct autotrasplants for patients with MS employing a simplification of the conventional procedures by means of non-frozen peripheral blood stem cells and outpatient conduction. Additional information is needed to asses the efficacy of these procedures in the treatment of patients with MS. Disclosures No relevant conflicts of interest to declare.

Abstract Stem cell mobilization after various induction regimens in patients with multiple myeloma Introduction: Rapid development of novel therapies for multiple myeloma has led to a significant improvement in response to the treatment. Stem cell mobilization before autologous stem cell transplantation is a source of considerable costs of transplant procedure. Whether modern induction regimens affect outcome of stem cell mobilization has not been extensively studied. Aim: The goal of this study was to compare efficacy of stem cell mobilization after different induction regimens in patients with multiple myeloma. The primary goal was to compare CTD (cyclophosphamide, thalidomide, dexamethasone), CVD (cyclophosphamide, bortezomib, dexamethasone) and VTD (bortezomib, thalidomide, dexamethasone) and regimens in terms of succesful stem cell collection. Methods: All patients with multiple myeloma who have been planned for stem cell collection and were treated with one of the above mentioned regimens were included in this retrospective analysis. The demographic data, amount of stem cells collected, number of days needed to reach the target collection were recorded. All patients received high dose cyclophosphamide 2,5 g/m2 prior to stem cell collection and were primed with G-CSF twice daily from day 5. The collection was started at day 10. Collection goal was 8x106/kg CD34+ cells. Results: 15 patients received CTD, 25 patients CVD and 16 patients VTD regimen before stem cell collection. Groups were comparable according to age, gender and myeloma stages. Mean collected cells at the end of collection were 9.2 (SD 2.8) for CTD, 12.3 (SD 5.6) for CVD and 10.1 (SD 2.1) for VTD (p=0.066). Mean daily harvest was 3.4, 8.0 and 7.6 x106/kg respectively (p=0.01). Mean days needed to reach desired harvest were 3, 2.25 and 1.6 days (p=0.001). No collection failure was observed. Conclusion: The best collection results were seen in patients after induction with CVD or VTD regimen. VTD regimen also required the least days for collection and seems to be most beneficial for cost of collection. CTD regimen shows the least efficacy in stem cell collection before autologous transplantation. All patients managed to harvest for at least one stem cell transplant. Figure 1. Figure 1.

From April 2003 to December 2006, 195 patients with de novo symptomatic myeloma and younger than 60 years of age were randomly assigned to receive either tandem transplantation up front (arm A, n = 97) or one autologous stem-cell transplantation followed by a maintenance therapy with thalidomide (day + 90, 100 mg per day during 6 months) (arm B, n = 98). Patients included in arm B received a second transplant at disease progression. In both arms, autologous stem-cell transplantation was preceded by first-line therapy with thalidomide-dexamethasone and subsequent collection of peripheral blood stem cells with high-dose cyclophosphamide (4 g/m2) and granulocyte colony stimulating factor. Data were analyzed on an intent-to-treat basis. With a median follow-up of 33 months (range, 6–46 months), the 3-year overall survival was 65% in arm A and 85% in arm B (P = .04). The 3-year progression-free survival was 57% in arm A and 85% in arm B (P = .02). Up-front single autologous transplantation followed by 6 months of maintenance therapy with thalidomide (with second transplant in reserve for relapse or progression) is an effective therapeutic strategy to treat multiple myeloma patients and appears superior to tandem transplant in this setting. This study was registered at www.ClinicalTrials.gov as (NCT 00207805).

Background: High-dose chemotherapy (HDCT) followed by autologous transplantation of hematopoietic stem cells (auto-HSCT) is an important component of treatment in multiple myeloma (MM). There is a standard method of controlled cryopreservation of HSC suspension. We found that the storage of native HSC suspension with temperature fluctuations from +3 °C to +5 °C during 72 - 120 hours does not significantly affect the content of CD34+ cells in the product, the index 7AAD- (7-AAD (7-aminoactinomycin - D) is a fluorescent marker that penetrates damaged cell membranes and binds to double-stranded DNA. Through 7AAD does not penetrate intact membranes, so living cells are not stained 7AAD with flow cytometry), and colony-forming ability (CFA) of HSC, as well as the recovery time of hematopoiesis in MM patients after auto-HSCT. Aim: To evaluate the effectiveness and safety of the method of storage of non-cryopreserved peripheral blood stem cells. Methods: 39 patients with MM were included in this study(male/female ratio 1.36:1). All the patients get standard immunochemotherapy programs and were in remission at the time of auto-HSCT. Patients were divided into two groups depending on the method of stem cell storage: group 1 - non-cryopreserved (n=20), group 2 - cryopreserved (standard) (n=19). An effectivity and safety were evaluated in such parameters as the number of CD34+ and 7AAD- cells, CFA after apheresis and before reinfusion of HSC.
