PURPOSE: The purpose of this study was to compare the effects of filgrastim, sargramostim, or sequential sargramostim and filgrastim on CD34+ cell yields and morbidity after myelosuppressive mobilization chemotherapy (MC). PATIENTS AND METHODS: One hundred fifty-six patients were randomized to receive filgrastim (n = 51), sargramostim (n = 52), or sargramostim for 5 days followed by filgrastim (n = 53) after MC with either cyclophosphamide and etoposide (n = 75) or paclitaxel and cyclophosphamide (n = 81). RESULTS: Compared with those who received sargramostim, patients who received filgrastim had faster recovery of an absolute neutrophil count of 0.5 × 109/L or greater (a median of 11 v 14 days; P = .0001), with fewer patients requiring RBC transfusions (P = .008), fewer patients with fever (18% v 52%; P = 0.001), fewer hospital admissions (20% v 42%; P = .013), and less intravenous antibiotic therapy (24% v 69%; P = .001). Patients who received filgrastim yielded more CD34+ cells (median, 7.1 v 2.0 × 106/kg/apheresis; P = .0001), and a higher fraction achieved 2.5 × 106 (94% v 78%; P = .021) and 5 × 106 (88% v 53%; P = .001) or more CD34+ cells/kg with fewer aphereses (median, 2 v 3; P = .002) and fewer days of growth-factor treatment (median, 12 v 14; P = .0001). There were no major differences in outcomes between the filgrastim alone and the sequential regimens. After high-dose chemotherapy, patients who had peripheral-blood stem cells (PBSCs) mobilized with filgrastim or the sequential regimen received higher numbers of CD34+ cells and had faster platelet recovery (P = .015), with fewer patients (P = .014) receiving fewer platelet transfusions (P = .001) than patients receiving sargramostim-mobilized PBSCs. CONCLUSION: It was concluded that filgrastim alone or sequential sargramostim and filgrastim were superior to sargramostim alone for the mobilization of CD34+ cells and reduction of toxicities after MC.

Abstract The prognosis for patients with severe refractory systemic lupus erythematosus (SLE) is poor; High dose chemotherapy with hematopoietic stem cell support is a salvage treatment under investigation for these patients. In our center, 17 patients with severe refractory SLE received autologous peripheral blood stem cells transplantation (PBSCT); Peripheral blood stem cells were mobilized with cyclophosphamide 4g/m2 and granulocyte colony-stimulating factor (G-CSF) 5 μg/kg/day. Enough PBSC were collected in all patients. There’s no mobilization-related mortality, while 3 patients developed active lupus after mobilization which was controlled by slightly increasing the dosage of steroids. Following conditioning with cyclophosphamide 6g/m2 plus anti-thymocyte globulin (ATG, 20mg/kg/d, 5 days), cryopreserved PBSC (mean MNC 4.28×108/kg and CD34(+) cell 2.48×106/kg) were infused. Median ANC and platelet engraftment time were days +11 and +12 after transplantation, respectively. Treatment related complications include mucositis (14/17), infection (12/17), liver malfuction (10/17), edema or/and heart failure (3/17), renal failure (2/17), bleeding (5/17); One patient died from cerebral hemorrhage. Median follow-up is 22 months (9–28 months); All the patients improved with the SLEDAI score reduced from 25.2±6.6 before to 9.7±1.2 3 months after transplantation; Steroids were stopped or maintained at very low dose (equal to 5 to 7.5 mg/d predinisone). One patient had overt lupus relapse 8 months following transplant Conclusions Mobilization, harvesting and transplantation of peripheral blood stem cells in patients with severe refractory systemic lupus erythematosus is safe; The short-term result of the approach is effective in this group of patients; More patients needed to enroll a control study to validate the role of high-dose chemotherapy/PBSCT as the salvage treatment for severe SLE.

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.
