Recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) has been used in two clinical studies at the Christie Hospital in Manchester, United Kingdom. Short daily "bolus" injections (over 30 min) were associated with serious toxicity which included bone pain, pruritus and pericarditis. In contrast, continuous infusions did not cause any toxicity and produced significantly higher increments of the peripheral neutrophil counts. rhGM-CSF reduced the period of life-threatening neutropenia following high-dose i.v. melphalan (120 mg/m2). Also, rhGM-CSF shortened the duration of thrombocytopenia induced by this chemotherapy to less time than has been seen historically in conjunction with autologous bone marrow rescue.

In a pilot study, five patients with myelodysplastic syndromes with an excess of blast cells were treated with a combination of recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) and low-dose cytosine-arabinoside (ara-C) in an attempt to selectively kill the leukemic blast cells and thereby to restore normal hemopoiesis. The treatment schedule consisted of three 14-day-cycles of 250 micrograms/m2 rhGM-CSF and 20 mg/m2 ara-C given daily s.c. with four-week treatment-free intervals. In all four evaluable patients the percentage of bone marrow blast cells decreased significantly with an increase in the mature myeloid cells but without bone marrow aplasia. Toxic side effects attributable to the drugs were minor with fever, mild bone pain, erythema and itching at the site of subcutaneous injection of rhGM-CSF. In conclusion, the combined therapy of rhGM-CSF and low-dose ara-C appears to be effective in the short-term control of the leukemic cell population.

Twenty patients with progressive metastatic solid tumours were entered into a study to evaluate the biological effects and toxicity of recombinant human granulocyte-macrophage colony-stimulating factor (GM-CSF). GM-CSF was given as half-hour intravenous infusions during two 10-day phases of daily treatments (separated by 10 days without GM-CSF) and over a final phase of 20 days of alternate day infusions. Doses were escalated in steps from 0.3 to 60 micrograms kg-1 day-1 between successive patient groups. Significant increases (P less than 0.005) of total leucocyte, neutrophil and eosinophil polymorph counts were seen over the periods of daily infusions (up to four-fold rises of total white count) at dose levels of 10 micrograms kg-1 and above. Counts produced at 30 micrograms kg-1 were significantly higher than at 10 micrograms kg-1 (P less than 0.025). Toxic side effects of GM-CSF included mild transient pyrexias, bone pain and pruritus. The maximum tolerated dose was 60 micrograms kg-1, which produced severe toxicity in 80% of patients. The toxicity at this dose included pericarditis and dyspnoea ascribed to a 'capillary-leak' syndrome. One patient receiving 60 micrograms kg-1 died as a result of a pulmonary embolus. Seven patients with previously rapidly progressive metastatic tumours experienced stabilisation of disease while receiving GM-CSF and one patient with a previously heavily pretreated metastatic soft tissue sarcoma underwent a greater than 50% reduction of tumour volume. Patients undergoing chemotherapy may benefit both from a reduction of the myelosuppressive effects of cytotoxic agents and from an antitumour effect if GM-CSF is incorporated into future regimens.

The application of recombinant colony stimulating factors for chemotherapy induced granulocytopenia is becoming common in clinical oncology. Here we report on localized cutaneous side effects after subcutaneous administration of recombinant human granulocyte-macrophage colony-stimulating factor (rh GM-CSF) in 11 patients with breast cancer receiving cytostatic treatment. Seven patients suffering from inflammatory breast cancer received cytostatic chemotherapy with mitoxantrone/cyclophosphamide, whereas four patients suffering from noninflammatory breast cancer received high-dose epirubicin/cyclophosphamide, respectively. rh GM-CSF was applicated subcutaneously in a dose of 5 micrograms/kg/d for at least ten days. In all patients, sharply demarked, maculous itching and burning erythemas restricted to the injection sites occurred after three to four injections of rh GM-CSF. These eruptions cleared within 2 to 3 weeks, but reappeared after reexposure to rh GM-CSF. In contrast to previous sporadic reports, no generalized erythemas were observed. Because of this unexpected and subjectively intolerable side effect, rh GM-CSF administration had to be interrupted in all patients. Histopathological findings revealed skin infiltration with lymphocytes, monocytes/macrophages, neutrophils, and occasionally eosinophils, respectively. Since GM-CSF is known to alter immune functions, it seems likely that the eruptions were at least in part due to local immune reactions.

The difference between the effects of administration of recombinant human granulocyte colony-stimulating factor (rhG-CSF) and recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) was studied in 39 children with neutropenia secondary to chemotherapy (absolute neutrophil count (ANC) less than 1,500/microliters. The children were divided into two groups. The first group (G-CSF) included 25 children (12 with acute lymphoblastic leukemia [ALL]-non-Hodgkin's lymphoma [NHL] and 13 with solid tumors) and the second group (GM-CSF) included 14 children (5 with ALL-NHL and 9 with solid tumors). All 39 children received of either G-CSF or GM-CSF (5 micrograms/kg/day) subcutaneously at the end of each chemotherapy course for a maximum duration of 14 days. The effect of G-CSF and GM-CSF on the ANC, the antibiotic therapy administration, and the length of hospital stay were studied for both groups at two cycles of chemotherapy. During both cycles a faster rise of ANC was observed in the children of the first group (G-CSF) compared with those of the second group (GM-CSF), but there was no difference in either the incidence of antibiotic therapy administration between the two groups (26% vs 25%) or the length of hospitalization. Both growth factors were well tolerated by all children studied with minimal side effects observed (including bone pain with G-CSF in 2 of 25 children and pruritus with GM-CSF in 1 of 14). We conclude that G-CSF reduces the duration of neutropenia more than does GM-CSF, but the incidence of severe infection and the duration of hospitalization do not differ between children receiving either G-CSF or GM-CSF.

Vaccination with irradiated granulocyte-macrophage colony-stimulating factor (GM-CSF)-secreting gene-transduced cancer vaccines induces tumoricidal immune responses. In a Phase I human gene therapy trial, eight immunocompetent prostate cancer (PCA) patients were treated with autologous, GM-CSF-secreting, irradiated tumor vaccines prepared from ex vivo retroviral transduction of surgically harvested cells. Expansion of primary cultures of autologous vaccine cells was successful to meet trial specifications in 8 of 11 cases (73%); the yields of the primary culture cell limited the number of courses of vaccination. Side effects were pruritus, erythema, and swelling at vaccination sites. Vaccine site biopsies manifested infiltrates of dendritic cells and macrophages among prostate tumor vaccine cells. Vaccination activated new T-cell and B-cell immune responses against PCA antigens. T-cell responses, evaluated by assessing delayed-type hypersensitivity (DTH) reactions against untransduced autologous tumor cells, were evident in two of eight patients before vaccination and in seven of eight patients after treatment. Reactive DTH site biopsies manifested infiltrates of effector cells consisting of CD45RO+ T-cells, and degranulating eosinophils consistent with activation of both Th1 and Th2 T-cell responses. A distinctive eosinophilic vasculitis was evident near autologous tumor cells at vaccine sites, and at DTH sites. B-cell responses were also induced. Sera from three of eight vaccinated men contained new antibodies recognizing polypeptides of 26, 31, and 150 kDa in protein extracts from prostate cells. The 150-kDa polypeptide was expressed by LNCaP and PC-3 PCA cells, as well as by normal prostate epithelial cells, but not by prostate stromal cells. No antibodies against prostate-specific antigen were detected. These data suggest that both T-cell and B-cell immune responses to human PCA can be generated by treatment with irradiated, GM-CSF gene-transduced PCA vaccines.

It is suggested that atopic dermatitis is a skin disease associated with itching as subjective symptoms, and histamine H(1) receptor antagonists are used in order to prevent the itching, and the deterioration for scratch by itching. Histamine H(1) receptor selective anti-histamine olopatadine hydrochloride (olopatadine; Allelock shows consistent efficacy and safety in the treatment of allergic disorders. We investigated the possible efficacy of olopatadine on the number of scratching induced by repeated application of oxazolone in BALB/c mice. The repeated treatment of olopatadine significantly inhibited the ear swelling and the increased number of scratching. It significantly inhibited the increased production of interleukin (IL)-4, IL-1beta and granulocyte-macrophage colony-stimulating factor (GM-CSF) in the lesioned ear. Moreover, it significantly inhibited the increased production of nerve growth factor (NGF) and substance P. On the other hand, loratadine, bepotastine and chlorpheniramine did not inhibit the ear swelling and the increased number of scratching. These results indicate that olopatadine inhibited not only the increased production of cytokines but also NGF and substance P unlike other histamine H(1) receptor antagonists. It was suggested that olopatadine suppressed the increased number of scratching by the anti-inflammatory effects. Therefore, olopatadine appears to exert additional biological effects besides its blockade of a histamine H(1) receptor.
