PURPOSE: Ganglioside GD2is strongly expressed on the surface of human neuroblastoma cells. It has been shown that the chimeric human/murine anti-GD2monoclonal antibody (ch14.18) can induce lysis of neuroblastoma cells by antibody-dependent cellular cytotoxicity and complement-dependent cytotoxicity. The purposes of the study were (1) to determine the maximum-tolerated dose (MTD) of ch14.18 in combination with standard dose granulocyte-macrophage colony-stimulating factor (GM-CSF) for patients with neuroblastoma who recently completed hematopoietic stem-cell transplantation (HSCT), and (2) to determine the toxicities of ch14.18 with GM-CSF in this setting.PATIENTS AND METHODS: Patients became eligible when the total absolute phagocyte count (APC) was greater than 1,000/μL after HSCT. ch14.18 was infused intravenously over 5 hours daily for 4 consecutive days. Patients received GM-CSF 250 μg/m2/d starting at least 3 days before ch14.18 and continued for 3 days after the completion of ch14.18. The ch14.18 dose levels were 20, 30, 40, and 50 mg/m2/d. In the absence of progressive disease, patients were allowed to receive up to six 4-day courses of ch14.18 therapy with GM-CSF. Nineteen patients with neuroblastoma were treated.RESULTS: A total of 79 courses were administered. No toxic deaths occurred. The main toxicities were severe neuropathic pain, fever, nausea/vomiting, urticaria, hypotension, mild to moderate capillary leak syndrome, and neurotoxicity. Three dose-limiting toxicities were observed among six patients at 50 mg/m2/d: intractable neuropathic pain, grade 3 recurrent urticaria, and grade 4 vomiting. Human antichimeric antibody developed in 28% of patients.CONCLUSION: ch14.18 can be administered with GM-CSF after HSCT in patients with neuroblastoma with manageable toxicities. The MTD is 40 mg/m2/d for 4 days when given in this schedule with GM-CSF.

PURPOSE Oral mucositis following high-dose chemotherapy may result in systemic infection and airway compromise, and the severity of oral mucositis may be dose-limiting. Here we investigate the effect of granulocyte-macrophage colony-stimulating factor (GM-CSF), which significantly shortens duration of neutropenia after hematopoietic stem-cell transplantation (HSCT) on oral mucositis. PATIENTS AND METHODS Thirteen children undergoing HSCT were prepared with etoposide (VP-16), thiotepa (TT), and total-body irradiation (TBI), and 13 with VP-16, TT, and cyclophosphamide (CPM). Following transplantation, 14 patients received GM-CSF at a dose of 125 micrograms/m2/d by continuous intravenous infusion (six prepared with VP-16, TT, and TBI, and eight prepared with VP-16, TT, and CPM), and 12 patients received no growth factor. RESULTS Mucositis was more severe and persisted longer in patients prepared with the TBI-containing regimen. For this regimen, the duration of severe oral mucositis was shortened by the administration of GM-CSF, although the severity of mucositis was unaffected. No statistically significant effect of GM-CSF could be shown in patients who received VP-16, TT, and CPM. The incidence of positive fungal oral or blood cultures did not appear different whether patients received GM-CSF or not. CONCLUSION For patients undergoing stomatotoxic HSCT regimens, GM-CSF may reduce the duration of oral mucositis, but is unlikely to effect the severity of oral mucositis or risk of airway compromise, and the severity of mucositis is likely to remain dose-limiting.

Stem cell factor (SCF) plays a crucial role in hematopoiesis through its interaction with the receptor tyrosine kinase c-kit. However, the signaling events that are activated by this interaction and involved in the control of growth or differentiation are not completely understood. We demonstrate here that Tec, a cytoplasmic, src-related kinase, physically associates with c-kit through a region that contains a proline-rich motif, amino terminal of the SH3 domain. Following SCF binding, Tec is tyrosine phosphorylated and its in vitro kinase activity is increased. Tyrosine phosphorylation of Tec is not detected in the response to other cytokines controlling hematopoiesis, including colony-stimulating factor-1 (CSF-1), granulocyte-macrophage colony-stimulating factor (GM-CSF), and interleukin-3 (IL-3). Conversely, the cytoplasmic kinase JAK2 is activated by IL-3 but not by SCF stimulation. The activation of distinct cytoplasmic kinases may account for the synergy seen in the actions of SCF and IL-3 on hematopoietic stem cells.

We are interested to know whether expression of a lineage-specific growth factor receptor is deterministic to lineage commitment during hematopoiesis. For this purpose, we introduced the human c-fms gene into the multipotential stem cell clone LyD9 and two myeloid progenitor clones, L-GM3 and L-G3, cells that differentiate in response to granulocyte/macrophage colony-stimulating factor (GM-CSF) and granulocyte (G)-CSF, respectively. Although LyD9 cells have differentiation potential to become macrophages, c-fms transfectants of LyD9 and L-GM3 cells did not differentiate in response to human macrophage (M)-CSF. However, c-fms transfectants of L-G3 cells differentiated to neutrophils in response to human M-CSF. These results indicate that the M-CSF receptor requires a specific signal transduction pathway to exert its differentiational and proliferative effects. Furthermore, the M-CSF receptor can convey a granulocyte-type differentiation signal possibly by cooperating with the G-CSF receptor signal transduction pathway. The c-fms-transfected LyD9 cells as well as the original LyD9 cells differentiated predominantly into GM-CSF- and G-CSF-responsive cells by coculturing with PA6 and ST2 stromal cells, respectively. The results indicate that differentiation lineage is not affected by premature expression of the M-CSF receptor. Instead, the stromal cell used for coculture apparently controls lineage-selective differentiation of the multi-potential stem cell line.

Purpose For recipients of allogeneic hematopoietic stem-cell transplantation (alloHSCT), we hypothesized that prophylactic therapy during neutropenia with granulocyte-macrophage colony-stimulating factor (GM-CSF) decreases invasive fungal disease (IFD). Patients and Methods We randomly assigned 206 patients undergoing alloHSCT to receive once-daily subcutaneous GM-CSF (5 to 7 μg/kg per day), granulocyte colony-stimulating factor (G-CSF; 5 to 7 μg/kg per day), or a combination of G-CSF and GM-CSF (2 to 3 μg/kg per day each). Treatment was started on day 5 after transplantation and was continued until the absolute neutrophil count was ≥ 1.5 × 109/L for 2 consecutive days. The primary outcomes were 100-day incidence of proven and probable IFD and response rate of antifungal treatment. Results For the intent-to-treat population, there was no significant difference in 100-day incidences of proven and probable IFD among the three groups. The antifungal treatment response was better in the GM-CSF group and G-CSF+GM-CSF group than in G-CSF group from day 22 to day 100 (P = .009). The 100-day cumulative mortality after transplantation was lower in the GM-CSF group than in the G-CSF group (10.3% v 24.6%, respectively; P = .037). The GM-CSF and G-CSF+GM-CSF groups had lower 100-day transplantation-related mortality than the G-CSF group (8.8%, 8.7%, and 21.7%, respectively; P = .034). After a median follow-up of 600 days, IFD-related mortality was lower in the groups that received GM-CSF or G-CSF+GM-CSF compared with G-CSF (1.47%, 1.45%, and 11.59%, respectively; P = .016). There were no significant differences in relapse, graft-versus-host disease, or hemorrhage-related mortality among the three groups of patients. Conclusion For recipients of alloHSCT, compared with G-CSF, prophylactic GM-CSF was associated with lower 100-day transplantation-related mortality, lower 100-day cumulative mortality, and lower 600-day IFD-related mortality.

Stem cell factor (SCF) is a cytokine for hematopoietic progenitor cells and plays an important role in megakaryocyte proliferation. The UT-7 cell line was established from a patient with megakaryoblastic leukemia, and its growth and survival are strictly dependent on interleukin-3 (IL-3), granulocyte-macrophage colony-stimulating factor (GM-CSF), erythropoietin (Epo), or IL-6. In this study, we showed that SCF also supported the growth of UT-7 in the absence of other cytokines and downregulated the cell surface c-kit receptors. Constitutive expression of SCF by introducing SCF expression vector made UT-7 grow factor-independently in liquid medium, but not in semisolid medium. This SCF-expressing factor-independent UT-7 (UT-7scf9) expressed the membrane bound form of SCF on their surface, but did not secrete detectable amounts of soluble SCF. UT-7scf9 formed aggregates as they grew in the absence of cytokines, and this aggregation was inhibited by adding soluble SCF into the medium. UT-7 cultured with SCF and UT-7scf9 cultured without cytokines expressed GM-CSF, and anti-GM-CSF neutralizing antibody partially inhibited their growth. These results suggest that SCF stimulated UT-7 proliferation partially through the autocrine-loop of GM-CSF, and UT-7scf9 expressed SCF mostly as a membrane-bound form, which transduces its growth signal through c-kit receptor as they aggregate by cell-to-cell interaction.
