Abstract This analysis studied 197 autologous HSCT performed in 132 patients treated for multiple myeloma (MM) in our center between 2000 and 2007. There were 53 females and 79 males with a median age of 56.8 years (34–72). At diagnosis there were 71 IgG (49κ, 22λ), 26 IgA (15κ,11λ), 2 IgD (1κ, 1λ), 27 light chain (18κ,9λ), 2 plasma cell leukemia, 3 non secretory, 1 non secretory/non excretory. There were 11 stage I (10A and 1B), 12 IIA, 96 III(75A and 21B) and 13 not classified. At diagnosis, 24/98pts had a del(13), and 65/179 had high levels of β2microglobulin. Before 2004, 50% of transplants were done and the median interval between diagnosis and HSCT was 7.8 months (3.5–131). We divided the population into 2 groups (I = 65: double-auto, II = 67 simple auto). The disease status pre-transplant according to the number of apheresis were: 1 apheresis (group I: 3CR, 29PR, 3SD, 1PD; group II: 2CR, 24PR, 3PD), 2 apheresis (group I: 16PR, 1SD, 1PD; group II: 3CR, 9PR, 1PD), 3 apheresis (group I: 1CR, 4PR; group II: 10PR, 1unknown), 4 apheresis (group I: 4PR, 1PD; group II: 1CR, 10PR, 2SD), 6 apheresis (group II: 1PR) and 8 apheresis (group: 1PR). PBSC were mobilized in steady state in 135 cases, 53 after cyclophosphamide alone, 9 cyclophosphamide with other drugs. During mobilization, we used GCSF in 179cases, GM-CSF in 5cases, SCF in 4 cases and associations of GM-CSF+ GCSF in 2(1%) cases and SCF+GCSF in 7(3.5%) cases. The median number of infused cells were: TNC 5×107/kg (1–59), CFU-GM 70.5×104/kg (0–2616) and CD34+cells 3×106/kg (0–27). Of these, 115 (58%) had a number of CD34+cells<4×106/kg and 82 (42%) ≥4×106/kg. As conditioning regimens, all pts received melphalan alone with a median total dose of 304mg [130–440]. After transplantation, 156(79%) have received growth factors [1(0.5%) GM-CSF, 148 (95%) G-CSF and 7 (4.5%) SCF] and 195 pts well engrafted (99%). Concerning red blood cell (RBC) transfusions, 60% of pts did not received any RBC transfusions, 30% received between 1 and 4 transfusions, 7% between 5 and 8 and 3% 10 or more and concerning platelet (Pt) transfusions, 35,5% did not received any Pt transfusions, 53% received between 1 and 3, 9% between 4 and 7 and 2.5% 10 or more. The median number of RBC and Pt transfusions were 0 [0–23] and 1 [0–20] respectively. The median number of days with neutrophils <0.5G/L was 6 (0–33) and with Pt<50G/L 17 (2–104) and the median length of hospitalization for auto transplantation was 18 days (14–54). The probability of 5-year overall and event-free survival (OS and EFS) were 64.3% (56.3–73.4%) and 32.4% (24.9–42.2%) and the median OS was not reached. Among all pts, 25 received an allogeneic HSCT as further treatment. Statistical analysis studied age disease status at transplant infused TNC, CD34+cell and CFU-GM, growth factors during mobilization and after transplantation, mobilization chemotherapy, interval Diag-T and transplantation period in a conditional logistic-regression model to analyze associations between these variables and length of hospitalization, number of RBC and Pt transfusions; a multivariate analysis using Cox model to analyze the impact of these variables on length of aplasia (<0.5G/L neutrophils and <50G/L Pt). We observed no significant impact of all studied variables on length of hospitalization and RBC transfusions and a significant negative impact of long interval diagnosis-T (p=0.05) and of the period > 2004 on Pt transfusion number (p=0.03). We showed a significant positive impact of CFU-GM number [HR=1 (1000–1.002) (p=0.03)] and growth factor use after transplantation [HR=0.55 (0.36–0.85) (p=0.005)] on days <0.5 G/L neutrophils and a significant negative impact of CD34+cell<4 ×106/kg on the number of days <50G/L Pt ([HR=1.65 (1.09–2.50) (p=0.01)]. A more refined analysis of the groups, as well as a medico-economic analysis are ongoing and will be presented. In conclusion, this retrospective analysis showed an interesting long-term overall survival probability for this high risk MM population. We demonstrated no apparent impact of the pre-transplant, mobilization, and graft variables on number of transfusions and the length of hospitalization in this global analysis. However, we did show a significant influence of the diagnosis-T interval on platelet transfusions and of the CD34+ cell number, GCSF post-transplant and CFU-GM number on the length of aplasia.

Abstract High-dose melphalan followed by ASCT is a common component of the early treatment for patients with multiple myeloma. Daily subcutaneous injections of filgrastim (Neupogen) at 5 ug/kg/day until ANC > 500/ul are routinely administered at our center from day +4 following ASCT, in order to accelerate hematopoietic recovery and lessen neutropenic complications. Pegfilgrastim (Neulasta) as a single 6 mg fixed dose subcutaneous injection has been shown to have similar efficacy and ease of use when compared to filgrastim in the non-transplant setting, but little data is available in the transplant setting. We began using pegfilgrastim day +1 following ASCT for patients with multiple myeloma and performed a retrospective cohort study comparing those who received filgrastim (n=6) with those who received pegfilgrastim (n=11). Transplants occurred between July 2002 and January 2004 and included all patients transplanted for myeloma in that time period for whom sufficient data was available. All patients had at least 2 x 106 CD34+ cells/kg peripheral stem cells harvested after cytoxan and filgrastim mobilization. Main outcome measures were: days from stem cell infusion to WBC nadir, days to ANC>500/ul, and days to ANC>1000/ul. Subjects were excluded if CBCs were drawn less frequently than every four days. There were no significant differences between the filgrastim and pegfilgrastim groups with respect to the following demographic variables: age, gender, hemoglobin, creatinine, calcium, albumin and beta-2 microglobulin at diagnosis. The groups were also balanced with respect to SPEP, UPEP, presence of lytic lesions and number of prior lines of therapy. The median number of CD34+ cells infused was similar: 5.7 x 106 in the filgrastim group vs 4.8 x 106 in the pegfilgrastim group (p=0.28). After transplant, median number of days to WBC nadir in the filgrastim group (FG) was 7 (range 5–9) vs 6 (range 5–8) in the pegfilgrastim group (PG) (p=0.31). However, median number of days to ANC>500/ul in the FG was 11.5 (range 11–17) vs 10 (range 9–12) for PG (p=0.02). Similarly, median number of days to ANC>1000/ul was 12 (range 11–17) for FG vs 11 (range 10–13) for PG (p=0.03). Five of six patients in the FG had neutropenic fever after transplant, compared to five of eleven patients in the PG (p=0.30). Currently, no significant differences in infection or relapse rates between groups have been noted and there were no deaths in either group. In this retrospective cohort study, pegfilgrastim was safe and at least equivalent to filgrastim for accelerating hematopoiesis after ASCT for multiple myeloma. Furthermore, there was no significant difference in the incidence of neutropenic fever, infection and survival, suggesting a similar clinical utility.

Abstract Background: AMD3100, an inhibitor of SDF1 binding to CXCR4, synergizes with G-CSF to allow mobilization of sufficient CD34+ cells/kg for autologous transplantation in pts unable to collect adequate CD34+ cells with G-CSF alone. Therefore, a single patient use (SPU) protocol for AMD3100 was adopted for more than one patient entry per site and termed Compassionate Use Protocol (CUP). The only difference of standard of care was the addition of AMD3100 to a G-CSF mobilization on the evening prior to each day of apheresis. Pts who could not proceed to apheresis due to low peripheral blood counts or pts who did not collect a minimum of 2 × 10^6 CD34+ cell/kg were eligible. Methods: Overall, more than 280 patients with proven poor mobilization including 137 NHL, 73 MM, and 31 HD have been included in CUP. A data audit was performed to validate data from pts with either non-Hodgkin’s lymphoma (NHL), multiple myeloma (MM), or Hodgkin’s Disease (HD). Sites were selected based on most patients entered, >3 of all diseases entered at a site, and sites conducting an AMD3100 trial. Audit included all pts, regardless of success or failure of the outcome; all information was collected on CRFs. Success of outcome was collection of ≥ 2×10^6 CD34+ cells/kg during the CUP procedure. CUP apheresis was done on day 5 after G-CSF (10mg/kg SC QD) and AMD3100 (240mg/kg SC Q10 PM) starting day 4. Results: Charts and CRFs were available for review for 115 pts; 63 (55%) were NHL patients from 29 sites, 35 (30%) were MM from 23 sites and 17 (15%) were HD from 13 sites. Of these pts, 58% were male, the median age was 59 years (range 21–77), 88% were Caucasian, and patient weight ranged from 43–128 kg. Prior treatments included a median of two regimens of chemotherapy in each of the three groups. Safety was generally favorable with no drug-related SAE’s and with an AE profile similar to that seen in research trials. The rates of successful collection of ≥ 2×10^6 CD34+ cells/kg per disease state as well as prior mobilization regimen are summarized in table 1. The median number of mobilizations for the successful patients was 3 days for NHL and HD and 4 for MM. Eighty-eight of the patients underwent transplantation with any cells. For example, of the 47 NHL patients transplanted, 24 had CUP only cells and 23 had mixed cells. The median number of days to engraftment was 11 for PMN and 18 for platelets. Long term follow up is limited, but there do not appear to be graft failures. At least 12 of the pts have died. Conclusions: AMD3100 in a poor mobilizer population is generally safe and well tolerated and is very effective in mobilizing > 2×10^6 CD34+ cells/kg.

Abstract Introduction Autologous stem cell transplantation (ASCT) is the standard treatment in multiple myeloma (MM) for eligible patients below 70 years of age. The main mobilization treatment in Europe consists of combination of cyclophosphamide (CY) and G-CSF. It is questionable if CY is useful in mobilization. CY as an alkylating agent might also have some negative long-term effects. Bortezomib seems not to have negative impact on autologous stem cell harvesting, but prolonged use of lenalidomide might hamper mobilization. There are only a few studies regarding autologous stem cell mobilization after RVD induction. We designed this randomized study as a substudy of the Finnish Myeloma Group Study (NCT01790737) to compare the results of CY+G-CSF versus G-CSF mobilization in autologous stem cell harvesting. The primary endpoint is the percentage of patients reaching ≥ 3 x 106/kg CD34+ cells (or ≥ 6 x 106/kg for two transplants), with ≤ 2 apheresis after low-dose CY+G-CSF vs. G-CSF mobilization. Secondary endpoints are need for plerixafor, graft cellular composition and engraftment after ASCT. Patients and methods This phase 2 study will include 80 patients below 70 years of age with symptomatic MM and eligible for ASCT. At registration the patients are randomized equally to arm A) CY 2 g/m2 + G-CSF 5 μg/kg or arm B) G-CSF 10 μg/kg. Before mobilization three RVD induction cycles are given. Each 3-week RVD cycle includes lenalidomide 25 mg daily on days 1−14, bortezomib 1.3 mg/m2 subcutaneously on days 1, 4, 8, 11, and dexamethasone 160 mg/cycle. By this schedule the first harvest is estimated to be on day +10 in CY + G-CSF and on day +5 in G-CSF group. Apheresis will start with blood CD34+ level >10 x 106/l. The target cell yields for one and two grafts are ≥ 3 and ≥ 6 x 106 CD34+ cells/kg, respectively, and the minimum for one graft ≥ 2 x 106/kg. Plerixafor is given if B-CD34+ cell count is less than 10 x 106/l on days +10 or +5, respectively, or if the first apheresis product contains < 1 x 106/kg CD34+ cells. G-CSF support is used after ASCT if the number of CD34+ cells in the graft is less than 3 x 106/kg. Engraftment will be assessed by blood neutrophil count > 0.5 x 109/l, and unsupported platelets > 20 x 109/l. Results Fifty-six patients have been included, and the mobilization data for the first 37 patients are available for analysis. The primary endpoint was reached in 90% of the patients (18/20) in arm A and in 82% (14/17) in arm B (p=NS). The median number of apheresis to reach the goal in arms A and B is one (1-3) and two (1−3), respectively (p=0.03). The median number of harvested cells in the two arms is 6.2 (2.2−12.1) and 4.8 (2.9−7.6) x 106/kg, respectively (p<0.01). All patients achieved the minimum collection target of ≥ 2 x 106/kg CD34+ cells in both arms, and the target yield of ≥ 3 x 106/kg was reached in 95% (19/20) in arm A and in 94% (16/17) in arm B. Plerixafor was used in two (12%) patients in arm B. The median blood CD34+ cell count on the first apheresis day was 55.9 (13.0−118.6) and 35 (16.0−148.5) x 106/l for arms A and B, respectively (p=0.44). The median time from mobilization day 1 to the first apheresis day was 10 (10−13) days in arm A and 5 (5−6) in arm B. The median number of CD34+ cells transplanted, was 4.1 (2.2−7.3) and 3.2 (2.3−4.7) x 106/kg in arms A and B, respectively (p=0.01). In arm A the median neutrophil engraftment was on day +14 (9−28) (16 patients) and in arm B on day +15 (11−25) (15 patients) (p=0.68). The median platelet engraftment days were +13 (8−22) and +11 (8−21) in arms A and B, respectively (p=0.67). At ASCT the response rates in arm A were ≥ VGPR 65% (13/20), PR 25% (5/20), and 10% (2/20) were progressing, and the respective rates for arm B were 70% (12/17), 18% (3/17),and 12 % (2/17). Conclusions Preliminary results of this randomized mobilization substudy with a limited number of patients show no clinically significant differences between the number of harvested CD34+ autologous stem cells. However, in CY+G-CSF group the CD34+ cell target was reached by less aphereses. After short induction course of RVD it seems possible to harvest also for two autografts with G-CSF only mobilization. However, when compared to historical data the CD34+ cell counts in blood and grafts were lower than after bortezomib + dexamethasone induction, and also neutrophil engraftment seemed to be slower after lenalidomide-based induction therapy. We conclude that CY can be omitted in the mobilization regimen for MM patients who have responded to short course of RVD.

Abstract Background: Bortezomib has become an integral part of front-line therapy of multiple myeloma in a large majority of patients. There are preliminary reports which show that addition of bortezomib can augment the peripheral blood CD34 count during stem cell mobilization. In this single center prospective trial we added bortezomib to G-CSF to evaluate the effects of bortezomib on peripheral CD34 counts and collection. Methods: Patients aged 18-70 years with diagnosis of multiple myeloma (MM) or non-hodgkin's lymphoma (NHL) who were eligible for autologous stem cell transplantation (ASCT) and had received no more than three prior chemotherapeutic regimens were eligible for the study. Patients were enrolled in two groups. Group A (N=3) received G-CSF 16mcg/kg for 5 days and proceeded to stem cell collection on D5 and then received bortezomib 1.3mg/m2 on D5 after stem cell collection and G-CSF 16mcg/kg on D6, 7, 8 and repeat stem cell collection on D6, 7, 8 till the goal was achieved. Group B (N=17) received G-CSF 16mg/kg on D1-5 and received bortezomib 1.3mg/m2 on D4 and proceeded to stem cell collection on D5. If the patient was not able to collect the predefined goal CD34, G-CSF was continued on D 6, 7, 8 and a second dose of bortezomib 1.3mg/m2 was given on D7. Mobilization procedure was stopped once the predefined goal CD34 collection (4 x 106/kg for MM and 2 x 106/kg for NHL) had been collected. Primary objectives of the study was to determine if addition of bortezomib to G-CSF will result in an increase in PBSCs by > 2-fold and to achieve median neutrophil engraftment 12 days post ASCT. Secondary objectiveswere to evaluate the collected product for co-mobilization of lymphoma or myeloma cells and to determine if the use of bortezomib increases the mobilization of immune-stimulatory Dendritic cell (DC) -1 subsets. Results: A total of 23 patients were enrolled and 20 were evaluable for the results. Only one patient with NHL was enrolled and rest had MM. Median age of pts was 57 years, M/F 8/12, median number of previous chemotherapy regimens was 1 (range 1-3). The median peripheral blood CD34 count pre and post bortezomib in all patients were 28.8 x 106/kg and 37 x 106/kg respectively. All three patients in group A had drop in peripheral blood CD34 counts on D6 post bortezomib as they had undergone stem cell collection on day 5. In part B (N=17), 15 patients had increase in peripheral blood CD 34+ve cell counts with 4 patients achieved doubling while 11 pts had less than doubling of peripheral blood CD34 count after receiving bortezomib. Two patients had minimal drop in the peripheral blood CD34 counts post bortezomib. Median number of CD34 cells collected in15 patients (part B) were 5.06 x 106 CD34 cells/kg (range 4-15.1). 18 patients proceeded to ASCT and median time to neutrophil engraftment (ANC ≥500/cumm) post transplant was 12 days (range 11-16) and platelet engraftment (Plt count ≥ 20,000/cumm) was 18 days (range 15-27). There was no significant change in DC1/DC2 ratio in both groups following treatment with bortezomib and G-CSF (Figure 1). In group A all three patients collected goal CD34 count on day 5 and 2/3 patients collected >4 x106 CD34 cells/kg on D6 post bortezomib and1/3 patients collected 2.6 x 106 on D6 post bortezomib. In group B (n=17), 2 patients were unable to collect because of low CD34 counts on D4 and D5, 11 pts collected the goal in one day (D 5) and 4 pts required two days of apheresis (D 5 and 6). None of the patients received D7 bortezomib. Conclusion: Use of bortezomib during autologous stem cell collection was safe and well tolerated. Majority of patients had increase in peripheral blood CD34 counts post bortezomib administration on D4. Future trials should explore bortezomib as an alternate strategy to chemo-mobilization in combination with growth factors. Figure 1. DC1/DC2 ratio in group A and group B at various time points.

Abstract Background: The need to repeat peripheral blood stem cell (PBSC) mobilization and collection arises infrequently in healthy donors, but may be required due to insufficient initial collection, graft failure, or relapse of the recipient’s disease. Currently no published data exists on the efficacy of remobilization of healthy PBSC donors. Studies of remobilization in patients undergoing autologous transplantation (ASCT) have largely focused on the use of alternative mobilization agents such as chemotherapy or plerixafor. Boeve et al (Bone Marrow Transplant, 2004) reported that remobilization with G-CSF in patients undergoing ASCT who failed initial mobilization with G-CSF, resulted in higher numbers of CD34+ cells collected than the initial collection, though this required a doubling of the dose of G-CSF. Patients/Methods: We performed retrospective chart review of 977 consecutive adult (>18 yrs) donors who underwent apheresis for PBSC donation at Washington University School of Medicine from 1995 through 2013. We identified 66 donors who had undergone more than one mobilization. Two cohorts of donors were identified for analysis: Group 1 included donors mobilized initially and again subsequently with G-CSF (10 ug/kg/day), or GM-CSF (5 ug/kg/day) + G-CSF (10 ug/kg/day). Group 2 consisted of donors mobilized with a CXCR4 antagonist, plerixafor (240-320 ug/kg) or POL6326 (1000-2500 ug/kg), and subsequently were remobilized with G-CSF (10 ug/kg/day). Statistical Analysis: Spearman correlations were performed to analyze the relationship between peak peripheral blood (PB) CD34+/uL level; the number of CD34+ cells collected per kg (recipient weight); and the number of CD34+ cells per L of apheresis collected during initial mobilization (MOB1) and remobilization (MOB2); and the interval (days) between MOB1 and MOB2. One-way ANOVA with repeated measures analyses were performed to determine the relationship of PB CD34+/uL, CD34+/kg and CD34+/L during MOB1 and MOB2. Results: Group 1 included 30 donors. The median age was 49 years (range 18-75) and 15 were male. The median number of days between MOB1 and MOB2 was 140 (range 26-2238). All 30 donors were remobilized due to graft failure or relapse of the recipient’s disease. PB CD34+/uL, CD34+/kg and CD34+/L all correlated between MOB1 and MOB2. The mean PB CD34/uL at MOB1 was 69 compared to 37 at MOB2 (p= 0.029); the mean CD34/kg collected at MOB1 was 5.6x106 compared to 3.3x106 at MOB2 (p= 0.002); and the mean CD34/L collected at MOB1 was 24.0x106 compared to 17.6x106at MOB2 (p= 0.023). The interval between MOB1 and MOB2 did not correlate with any of the MOB2 variables. Results from the analysis are summarized in Table 1. Group 2 included 32 donors. The median age was 51 years (range 21-67) and 18 were male. The median number of days between MOB1 and MOB2 was 20 (range 4-1123). 18 donors were remobilized due to mobilization failure, while 14 were remobilized due to graft failure or relapse of the recipient’s disease. The mean PB CD34/uL at MOB1 was 15 compared to 68 at MOB2 (p< 0.001); the mean CD34/kg collected at MOB1 was 2.5x106 compared to 7.1x106 at MOB2 (p< 0.001); and the mean CD34/L collected at MOB1 was 10.6x106 compared to 30.1x106at MOB2 (p< 0.001). The interval between MOB1 and MOB2 did not correlate with any of the MOB2 variables. Results from the analysis are summarized in Table 2. Conclusion: Remobilization with G-CSF or GM-CSF and G-CSF after initial successful mobilization with the same regimen results in poorer mobilization while remobilization with G-CSF after initial mobilization with a CXCR4 antagonist results in dramatically improved mobilization. The reason for this remains unclear, but in this study the interval between collections was not associated with successful remobilization. Abstract 850.

Pluripotent stem cells of hematopoiesis and lymphopoiesis are among the CD34+ cells in blood or bone marrow. After granulocyte-colony stimulating factor (G-CSF) treatment, 1% to 2% of the mononuclear cells in blood are CD34+ cells, which can be procured by leukapheresis. We investigated the potential of CD34+ blood cells for reconstituting hematopoiesis and lymphopoiesis after allogeneic transplantation. HLA- identical sibling donors of 10 patients with hematologic malignancies were treated with G-CSF (filgrastim), 5 microgram/kg subcutaneously twice daily for 5 to 7 days. CD34+ cells were selected from the apheresis concentrates by immunoadsorption, concomitantly the number of T cells was reduced 100- to 1,000-fold. After transplantation, five patients received cyclosporine A for graft-versus-host disease (GvHD) prophylaxis (group I); five patients additionally received methotrexate (group II). G-CSF and erythropoietin were given to all patients. Mean numbers of 7.45 x 10(6) CD34+ and 1.2 x 10(6) CD3+ cells per kilogram were transplanted. In group I, the median times of neutrophil recovery to 100, 500, and 1,000 per mm3 were 10, 10, and 11 days, respectively. Group II patients reached these neutrophil levels after 10, 14, and 15 days, respectively. Platelet transfusions were administered for a median of 18 days in group I and 30 days in group II, and red blood cells for 9 and 12 days, respectively. Between day 30 and 60, lymphocytes reached levels of 353 +/- 269 cells per mm3. The median grades of acute GvHD were III in group I and I in group II. Two patients in group I died from acute GvHD. Two leukemic relapses occurred in group II. Complete and stable donor hematopoiesis was shown in all patients with a median follow up of 370 (45 to 481) days. Allogeneic blood CD34+ cells can successfully reconstitute hematopoiesis and lymphopoiesis. Reduction of T cells by CD34+ blood cell enrichment and cyclosporine A alone might not be sufficient for prophylaxis of severe acute GvHD.

Abstract HCT after RIC is used increasingly to treat older or infirm patients with AML or MDS. In the current analysis we looked for risk factors influencing outcome including cytogenetics, kinetics of donor CD34+ and T-cell chimerism (CC). Patients and methods: From July 1998 - December 2005, 119 consecutive patients [66 m/53 f; median age 60 (range 21–74) years] with AML (n=99; 83%) and high-risk MDS (n=20; 17%) were treated within the OSHO AML studies before HCT. Seventy (59%) of the patients had intermediate-risk cytogenetics and 44 (37%) high-risk cytogenetics. Patients were either in CR1 (n= 66; 55%), CR2 (n=18; 15%), >CR2 (n=28; 24%), or were untreated (n=7; 6%) at transplant. HCT was performed from matched related (n= 33; 28%) and matched unrelated (n= 86; 72%) donors after RIC (200cGy TBI + fludarabine 30 mg/m2/day on 3 consecutive days) and followed by immunosuppression with cyclosporine and mycophenolate mofetil. Marrow donor chimerism was determined in T-, and CD34+−cells at days (d) 28, 56, 84, and thereafter at 3 month intervals using either XY chromosome FISH in gender mismatched, or PCR based analysis of polymorphic micro satellite regions in gender matched HCT. Results: Engraftment was documented in 112 (94%) of the 119 patients. Survival (OS), disease free survival (DFS), relapse incidence (RI), and non-relapse mortality (NRM) of engrafted patients was 40%, 38%, 46%, and 30% at 3 years respectively. In multivariate analysis, only >90% donor CD34+ CC at d 28, chronic GvHD, and CR1, but not cytogenetic risk factors were associated with an improved OS and DFS. Patients with >90% donor CD34+ CC at d 28 (group I) had an OS of 50% compared to 9% in patients with donor CD34+ CC <90% (group II) (p=0.002). Accordingly, RI in group I was 35% compared to 85% in group II (p<0.0001). Again, donor CD34+ CC at d 28 but neither donor T-cell chimerism nor high-risk cytogenetics correlated with relapse. Relapse occurred in 41/109 (38%) patients at a median of 121 d. All patients (n=19) with haematological relapse within 100 days post transplant died despite reduction/withdrawal of immunosuppression. Of the 22 patients with later relapse, six went into permanent complete remission by reduction/withdrawal of immunosuppression. A decrease of CD34+ chimerism was detected in a further six patients and all responded to a decrease in immunosuppression. The incidence of acute (grades ≥ I) and chronic (limited and extensive) GvHD was 50%, and 55% respectively. OS was 10%, 46%, and 62% for patients with no GvHD (A), acute GvHD only (B), and chronic GvHD (C) (p=0.0001). DFS for A, B, C was 20%, 38%, and 55% respectively ((p=0.0001). RI was highest for A (72%) compared to B (49%) and C (25%) (p<0.0001). Conclusions: HCT after RIC offers long-term OS and DFS in AML/MDS even in patients with high-risk cytogenetics. CR1, donor CD34+ CC >90% at d 28 and chronic GvHD correlate with an improved outcome and decreased relapse incidence. Careful monitoring of donor CD34+ CC can identify patients at risk for relapse, thereby allowing early immunmodulation.

Abstract Abstract 2994 Patients affected by hematologic malignancies might benefit from high dose chemotherapy followed by peripheral stem cells (PBSC) transplant. Chemotherapy in combination with G-CSF is effective in mobilizing stem cells but often toxic, might require prolonged hospitalization and extensive supportive care. Moreover a high proportion of patients, ranging from 11 to 53%, fail to collect an adequate number of stem cells with this approach. In this setting plerixafor, a CXCR4 chemokine antagonist, has shown to increase the number of circulating CD34+ cells in cancer patients when used alone or with G-CSF and to be able to rescue patients unable to mobilize with traditional regimens. Recently, several forms of biosimilar nonglycosylated recombinant human G-CSF have been clinically developed and approved by the European Medicines Agency for the same indications as the reference filgrastim product on the basis of comparable quality, efficacy, and safety. Biosimilars also provide a more cost-effective strategy and their use in clinical setting may provide cost savings in their indicated uses. From December 2010 to July 2011, 16 patients, median age 55 (19–67), affected by Non-Hodgking Lymphoma (6), Hodgking Disease (2) and MM (8), received a combination of biosimilar version of G-CSF (Tevagrastim) and plerixafor in order to mobilize PBSC as first line strategy. Tevagrastim was self-administered (10μg/kg/die) for 3 days; on day 4 patients were admitted to the hospital, circulating CD34+ cells counted and if >20 cells/μl, plerixafor was administered (0.24mg/kg) 12 hours before the scheduled apheresis. There were 7 males and 9 females, median lines of previous chemotherapy was 1(1–4). Median number of circulating CD34+ cells on day 4 was 16 (8–42). Plerixafor was administered to all but 1 patients who had already 42 CD34+ cells/μl on day 4. On day 5, after plerixafor administration median number of circulating CD34+ cells had raised to 68/μl (18–138). All the patients underwent leukapheresis and were able to collect an adequate number of CD34+ cells necessary for the transplantation procedure with a median number of 5.2 ×106 (2.2–10.6) CD34+cells/kg in a median number of 1 procedure (1–2). For patients with Multiple Myeloma, 6/8 patients were able to collect a median of 5.8×106 CD34+/kg (4.2–10.6) in a single procedure. No major side effect was observed. So far, 7/16 patients underwent high dose chemotherapy followed by PBSC transplant. Engraftment occurred in all patients with a time to ANC>500 of 12 (9–13) and of PLT>20.000 of 13 (9–19) days. The combination of tevagrastim and plerixafor is safe and effective in mobilizing PBSC and allows a collection of a more than adequate number of cells in most of the patients in a maximum of 2 apheresis procedure, even in patients with MM who need to collect a double amount cells. Disclosures: No relevant conflicts of interest to declare.

Abstract Multiple myeloma and non-Hodgkin lymphoma and its treatment are frequently associated with increased tromboembolic risk, particularly venous trromboembolism (VTE), cerebrovascular ischemic events and myocardial infarction. The incidence of thrombotic complications dramatically raise after highly prothrombotic therapeutic regimens e.g. thalidomide and lenalidomide in MM. The current study was designed to examine whether procoagulant microparticles (MPs) derived from endothelial cells (EMPs) and platelets (PMPs) constitute an enhanced risk for venous thrombosis in MM and nHL patients (pts). We studied 39 pts without history of VTE, 17/22 F/M, aged 24-84 years (mean=60,23±13,45). There were 25 MM pts (15 cases of IgG, 3 of IgA, 1 IgM, 2 non secretory MM, 3 LCD) and 14 nHL (6 cases of DLBCL, 2 anaplastic T cell lymphoma, 2 FL, 4 MCL). All patients underwent routine coagulation tests. Flow-cytometry was used for quantification of endothelial cell (CD133+) microparticles (EMPs) and platelet (CD61+) microparticles (PMPs). In all pts ultrasound examination of venous system of lower extremities was performed. Deep and superficial veins of both limbs were evaluated. Conventional and Doppler imagination, as well as elastography and options to detect microcalcifications (micropure) were used. The ultrasound examination revealed the presence of vein thrombosis in 18 pts (group I, n =18). 11 out of 18 pts with bilateral lesions in VSM (vena saphena magna, great saphenous vein) and lower leg veins or bilateral in VSM only comprised subgroup Ia. 7 pts with unilateral blood clots in VSM formed group Ib. Thrombosis was observed in 11 pts with MM and 7 with nHL, and bilateral thrombotic lesions were demonstrated in 6 MM and 5 nHL pts. The remaining 21 pts showed no thrombosis (group II). The most frequently thrombosis was observed in IgA-MM (3/3 pts), followed by IgG-MM. In nHL patients thrombosis was found the most frequently in DLBCL. Patients were divided into two groups according to the age: > 60 yrs and <60 yrs. Both in MM and nHL, thrombosis was more frequent in older patients. The mean percentage of EMPs (CD133+) was 1,44±1,22 (median 0,95, IQR 0,47-2,31), and it did not differ (p=0,83) between thrombotic (group I) (1,48±1,16) and non-thrombotic pts (group II) (1,46±1,31), however the greatest value was assessed in the subgroup Ia (1,74±1,26, p=0,3467). Also, there was a trend marked that EMP percentage was lower in MM patients (1,25±1,31) in comparison to nHL patients (1,76±1,04), p=0,0671 (UM-W test). EMP percentage did not differ according to sex and age. The percentage of PMPs (CD61+) was 12,06 ± 6,31 (median 10,88, IQR 8,35-15,90), and higher in group I (12,65±3,25) vs. group II (10,93±7,68), p=0,0459 (UM-W test), including subgroup Ia (13,05±3,66), p=0,0885 (UM-W test). The mean PMPs percentage was similar in MM (12,27±7,18) vs. nHL (11,70±4,71), and as EMPs percentage, did not differ according to sex and age. Mean plasma fibrinogen (FBG) concentration was 3,95±1,82 g/L and did not significantly differ in MM and nHL patients with and without thrombosis (3,84±1,68 vs. 4,10±2,06 g/L), also it has similar level in subgroup Ia (4,06±1,97 g/L). Mean D-dimer level was 2,29±4,15 mg/L (median 1,30, IQR 0,54-2,35), and there was not significantly different in patients with and without thrombosis (2,95±5,29 vs. 1,34±1,25 mg/L), moreover it was not elevated in subgroup Ia (1,96±1,02 mg/L). Type of the disease, sex as well as age did not influenced FBG and D-dimer levels. Venous thrombosis was confirmed in nearly half of patients with newly diagnosed patients with MM and n-HL. In patients with many thrombotic lesions elevated activity of platelets (PMPs) was observed, as well as a trend towards elevated activity of endothelial cells (EMPs).

The prevalence of oral candidiasis and its association with malnutrition in terms of protein–energy malnutrition and mineral and vitamin depletion were evaluated in ninety-seven hospitalised older adults aged 82·1 (SD 8·6) years. Patients underwent a complete oral examination with microbiological investigation on admission to our geriatric rehabilitation unit. Patients were assessed nutritionally by evaluation of dietary intake and measurement of anthropometric variables, serum nutritional proteins, ferritin, Zn, folate, vitamins B12 and C. The prevalence of oral candidiasis was 37% (n 36); the proportion of patients with BMI <20 kg/m2 was 32% (n 31). The nutritional status of the population was studied by comparing two groups defined according to the absence (group I; n 61) or presence (group II; n 36) of oral candidiasis. The two groups did not differ on the basis of BMI and mid-arm circumference. However, group II had a smaller leg circumference, lower daily energy and protein intakes, lower albumin and transthyretin levels. Patients successfully treated with fluconazole increased their intake on day 30. The proportion of patients with hypozincaemia (<12·5 μmol/l) and vitamin C deficiency (<0·7 mg/l) was higher in group II. Treatment with antibiotics, poor oral hygiene, denture wearing, and vitamin C deficiency appeared as the most significant independent risk factors associated with oral candidiasis. The present findings show that oral candidiasis appears to be related to malnutrition and results in mucosal lesions that have a negative impact on energy intake, which may subsequently worsen nutritional status.
