Abstract Abstract 502 Autologous stem cell transplantation with PBSC after high-dose chemotherapy remains standard therapy for patients with symptomatic Multiple Myeloma (MM). Strategies to minimize complications could significantly reduce the morbidity of that procedure. One possibility could be to shorten the duration of induced neutropenia through the injection of an ex-vivo expanded graft. Nineteen patients (pts) received EVEC after high-dose Melphalan (HDM) (200 mg/m2) as the only graft. The ex-vivo expanded procedure has been described elsewhere (Boiron et al. Transfusion 2006 and Ivanovic et al. Transfusion 2006). Briefly, thawed peripheral blood CD 34+ cells collected after G-CSF mobilisation and selected with immunomagnetic devices were incubated for 10 days in a serum free medium (Maco Biotech HP01) with Stem Cell Factor (Amgen), G-CSF (Amgen) and TPO (Amgen: 7 pts; Cellgenix:12 pts). The expanded cells were then thoroughly washed and injected 48h after the HDM injection. The ex-vivo expansion lead to a median fold of 5,4 for CD34+ cells (1,3-11,8); 118 for CD33+ (1-703880); 3386 for CD14+ (4-101075); 28,5 for CD13+ (10-703880) and 13 for CFUs (6-21). The median N° of CD34+ cells injected was 14×10e6/kg (5,3-48). The results of these transplants were compared to those achieved in 38 pts who received unmanipulated PBSC after HDM. Pts and controls were matched for age, sex, stage of the disease, first line chemotherapy ( VAD or VD) status of the disease at time of transplant, year of transplant, time between diagnosis and transplant, CD34+ mobilisation technique (HD cytoxan + G-CSF or G-CSF alone) and the median N° of total nucleated cells and of CD34+ collected. The results are summarized on the table: There was no secondary neutropenia in the patients who received EVEC. With a median FU of the entire cohort of 30 m, the median OS for pts who received their first transplant with EVEC and with PBSC is 69 m and not reached respectively (p=NS), the median PFS is 18 m and 27 m (p = NS) and the median time to progression is 14 m and 15 m (p=NS). Conclusion: EVEC is feasible, safe and reduce significantly the morbidity of autologous stem cell transplantation after HDM for multiple myeloma. Disclosures: Milpied: Amgen France: Honoraria.

Abstract The efficacy of Pegfilgrastim (PF) in decreasing the duration of neutropenia has been proved after standard dose of chemotherapy. Results of PF after high dose chemotherapy (HDC) and autologous peripheral blood stem cells transplantation ASCT) are lacking. We studied the efficacy of PG in patients receiving HDC and ASCT for lymphoproliferative disease. Fifteen consecutive patients (8 males; 7 females) were onrolled in the study from September 2003 through March 2004. Median age of the patients was 56 years. Diseases were multiple myeloma in 5 patients, diffuse large cell non-Hodgkin’s lymphoma (NHL) in 3 patients, follicular lymphoma in 4 patients, mantle cell lymphoma in one patient, and primary central nervous system lymphoma PCNSL) in 2 patients. All patients were eligible for HDC and ASCT per institutional criteria. Stem cells were collected with peripheral blood pheresis after high dose cyclophosphamide (7 cases); high dose Ara-c (5 cases); ifosfamide (1 case); CHOP-like chemotherapy (1 case); or in steady state (1 case). All the patients received daily G-CSF (5 to 10 mcg/kg). Three different conditioning regimens were used. Patients with multiple myeloma received high dose melphalan (200 mg/m²), patients with PCNSL received a combination of high dose Thiotepa (750 mg/m²), Busulfan (12 mg/kg), and Cyclophosphamide (120 mg/kg), and patients with NHL received a BEAM chemotherapy. PF was administered as a single subcutaneous injection of 6 mg at day +3 after stem cell infusion, except for one patient whose injection was done on day 4. No adverse event attributable to PF was observed. There were no toxic death on study. All patients engrafted neutrophils and platelets. The median time to neutrophils engraftment (> 500/mm3) was 7 days (range, 4–12). Febrile neutropenia was almost constant (14/15) but never exceed OMS grade 2. Median number of days with IV antibiotics was 7 days (range 5–22). These preliminary data show that a fixed dose of 6 mg of PF given subcutaneously at day +3 after HDC and ASCT is safe and effective. A cost efficacy study is warranted to compare PF and daily dose of standard G-CSF after ASCT.

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 3494 Introduction: Treatment of multiple myeloma (MM) patients (<65 yrs) consists of induction chemotherapy for 3–6 months followed by peripheral blood stem cell collection and transplantation. Both high dose cyclophosphamide (HD-C, 2 gr/m2/day, on days 1–2) and lower dosage of cyclophosphamide (1 gr/m2/i.v.on day 1) combined with doxorubicin (15 mg/m2/day, on days 1–4) and dexamethason 40 mg orally, days 1–4 (LD-C) are used, in combination with G-CSF, to mobilize hematopoietic stem/progenitor cells. A great variability was observed in the engraftment of different hematopoietic lineages post-ASCT. Therefore we questioned whether the dose of cyclofosfamide as mobilizing agent might affect the neutrophil and platelet recovery post-ASCT. The studied MM patients were treated with VAD or TAD (Blood 2010;11:115). Peripheral blood stem cells were collected after LD-C and HD-C with the Cobe Spectra; in each collection, 10 – 12 L of blood was processed in 3 – 4 hours. The target yield was 10 × 106/kg CD34+ cells. Results: 92 patients were treated according to VAD and 41 patients with TAD. In the VAD arm 89% of the patients reached the target yield of CD34+ cells after 1 collection compared to 61% in patients treated with TAD (p = 0.0003). The number of CD34+ cells collected at the first day and the total CD34 yield after HD-C or LD-C was significantly higher in patients treated with VAD compared with TAD: 16.6 ± 11.6 × 106/kg vs. 10.4 ± 9.3 × 106/kg (p=0.003), and 16.9 ± 11.1 × 106/kg vs 12.3 ± 8.6 × 106/kg (p=0.02). No significant difference was observed in the total yield of collected CD34+ cells in the VAD arm or TAD arm between HD-C vs. LD-C. In all patients high dose melphalan (200 mg/m2) was used as conditioning regimen followed by reinfusion of peripheral blood stem cells. In the VAD arm no difference in neutrophil and platelet engraftment (absolute neutrophil count > 0.5 × 109/L and platelet count > 20 × 109/L without platelet transfusions) was noticed between patients mobilized with LD-C (22 ±12 days and 23 ±13 days) or HD-C (18 ± 5 (p=0.1) and 21 ±11 days (p=0.5)); in contrast a significant difference was demonstrated in neutrophil and platelet engraftment between patients treated according the TAD arm and mobilized with LD-C (20 ± 8 days and 20 ±19 days) or HD-C (34 ± 11 days (p<0.0001) and 43 ±22 days (p=0.001)). These differences could not be ascribed to differences in the number of infused CD34+ cells: VAD arm: LD-C: 5.7 ± 2.6 × 106/kg, HD-C: 5.7 ± 2.5 × 106/kg: TAD arm: LD-C: 5.2 ± 2.5 × 106/kg and TAD-HD-C 6.4 ± 2 × 106/kg. It might be assumed that the higher dosage of cyclophosphamide had a positive effect on tumor response. However the impaired engraftment was not associated with differences in relapse free survival between the different arms (p = 0.2). In summary these data demonstrate that thalidomide containing regimen in MM patients impair mobilization of stem/progenitor cells and that a mobilization with high dose cyclophosphamide and not low dose cyclophosphamide after treatment with thalidomide prolong the engraftment post-transplantation.
