Filgrastim (granulocyte colony stimulating factor) recently became commercially available for the treatment of chemotherapy-induced neutropenia. Studies have shown that filgrastim induces a dose-dependent granulocytosis in humans, thereby shortening the period of neutropenia in patients treated conventionally with submarrow ablative doses of chemotherapy, as well as with marrow ablative therapy given in the bone marrow transplant setting. By reducing the incidence and severity of infections and mucositis in patients treated with chemotherapy, it has a significant economic impact since it shortens the duration of antibiotic administration and hospitalization. Adverse reactions reported are limited to mild to moderate bone pain. Several other potential applications are being investigated for filgrastim, including treatment of patients with myelodysplastic syndrome and congenital neutropenia.

The authors administered recombinant human granulocyte colony-stimulating factor (rhG-CSF) to 16 patients with advanced non-Hodgkin's lymphoma treated with combination chemotherapy. Groups of three to five patients were treated with 50, 100, 200, and 400 micrograms/m2 per day of rhG-CSF by intravenous infusion for 14 days, beginning 3 days after chemotherapy. There was a strong linear relationship between the dose and the area under the curve over this dose range. The rhG-CSF was rapidly cleared from serum, with a mean half-life of 5.97 hours for the second phase (t1/2). In patients treated with a dose of more than 100 micrograms/m2 per day, the duration of neutropenia (P less than 0.01) and the duration of fever (P less than 0.05) were significantly decreased. The rhG-CSF was well tolerated and the only clinical observation that appeared relating to rhG-CSF administration was slight bone pain. This study strongly suggests that an optimum dose of rhG-CSF in patients after chemotherapy is 100 to 200 micrograms/m2. Our study shows that rhG-CSF is a clinically useful drug for patients treated with myelosuppressive chemotherapy.

Recombinant granulocyte colony-stimulating factor (rG-CSF) is a glycoprotein hormone which has been produced in mammalian cells and, in a nonglycosylated form, in the bacterium Escherichia coli through recombinant DNA technology. It stimulates proliferation, differentiation and activation of cells of the neutrophil-granulocyte lineage and has been investigated as therapy for patients with various neutropenic conditions, both iatrogenic and disease related. rG-CSF is well tolerated, the most frequently reported adverse effect being mild to moderate bone pain. A major use for rG-CSF therapy will be in ameliorating the neutropenia which follows cytoreductive chemotherapy. rG-CSF accelerates neutrophil recovery after chemotherapy, leading to a reduction in duration of the neutropenic phase. Consequently, infection rate is diminished, as is the associated usage of antibiotics and duration of hospitalisation. The implications are that rG-CSF may allow increased dose intensity and stricter adherence to chemotherapy schedules. The increase in neutrophils produced by rG-CSF renders it a useful treatment for conditions such as congenital, acquired and cyclic neutropenias for which current therapy is not very successful. rG-CSF may be an effective therapy in myelodysplasia, although there is concern about acceleration of the possible rate of conversion of this disease to acute myelogenous leukaemia. It is also likely that rG-CSF will be useful in accelerating the recovery of transplanted bone marrow in patients with leukaemia, lymphoma and solid tumour. Furthermore, there is great potential for expansion of the role of rG-CSF as monotherapy or in combination regimens with other cell factors in various haematological disorders such as aplastic anaemia. In summary, while many aspects of its use remain to be clarified, rG-CSF must be seen as an exciting advance in therapeutics. It should rapidly find an important place as an adjunct to cancer chemotherapy, and also appears to have substantial potential in a number of other neutropenic conditions which are currently difficult to treat.

Bacterially synthesized human granulocyte colony-stimulating factor (G-CSF) and granulocyte macrophage colony-stimulating factor (GM-CSF) have been studied to determine if they could prevent or reduce the neutropenia caused by chemotherapy. Our studies suggest that 10 micrograms/kg/day of G-CSF administered as a continuous subcutaneous infusion abrogates the neutropenia associated with a standard dose of melphalan. G-CSF produced a rapid increase of neutrophil levels, was well-tolerated, and was associated with only one frequent adverse effect: bone pain. GM-CSF, administered in doses ranging from 3 to 15 micrograms/kg/day subcutaneously, appeared to be useful in abrogating the neutropenia associated with chemotherapy, producing elevations in neutrophils, eosinophils, and monocytes. Although GM-CSF was relatively well-tolerated, several adverse effects, including bone pain, rashes, and fluid retention, were observed. The initial dose of GM-CSF in some patients produced a reaction that was characterized by hypoxia.

A phase I/II study of recombinant human granulocyte colony-stimulating factor (rhG-CSF) in 24 leukemia patients was conducted at our institute. Recombinant human G-CSF (50-200 micrograms/m2/day) was administered i.v. In seven allogeneic bone marrow transplantation (BMT) recipients, treatment with rhG-CSF was started 5 days after BMT. Neutrophils began to increase within 3 days after the start of rhG-CSF administration in five of seven patients. The mean duration necessary for recovery of neutrophils to greater than 500/microliters was 11.3 days after BMT with rhG-CSF; 26.8 days is the figure for recovery without rhG-CSF from Japanese historical data. In seven out of eight patients who received rhG-CSF administration after the first remission-induction chemotherapy, the neutrophil counts increased from less than 300/microliters to greater than 4000/microliters within 10 days. Blasts did not increase in all patients including four acute nonlymphocytic leukemia (ANLL) patients. Severe infections such as septicemia and pneumonia, which were unable to be controlled by antibiotics only, were successfully treated with rhG-CSF and antibiotics. rhG-CSF either stimulated or inhibited myeloid leukemic cells in some refractory cases. Mild bone pain occurred in one patient while receiving rhG-CSF i.v. rhG-CSF seems to have the ability to shorten the period of neutropenia, prevent infections after allogeneic BMT and remission-induction chemotherapy for acute leukemia, and support therapy for infections.

The effect of recombinant human granulocyte colony-stimulating factor (G-CSF) on hematologic parameters was evaluated in a phase I clinical study in 18 patients with advanced malignancy. G-CSF was administered once daily as a 30-minute infusion for 14 days; three patients each were treated at increasing dose levels of 1, 3, 10, 30, and 60 micrograms kg-1 day-1. A transient decrease in neutrophil and monocyte counts was observed immediately after the G-CSF infusion, followed by a dose-dependent increase of up to 15-fold. G-CSF-induced neutrophils exhibited an increased O2- radical production, and serum levels of enzymes related to granulocyte turnover, including lysozyme and elastase, were markedly elevated during therapy. A dose-dependent depression of platelet counts occurred in the second third of the treatment course, followed by a spontaneous recovery despite continuing therapy. G-CSF was well-tolerated; minor to moderate bone pain was the most common side effect. The primary course of the malignant diseases studied was not significantly altered. G-CSF appears to be an appropriate means to selectively increase the number of functionally competent polymorphonuclear phagocytes.

To determine whether recombinant human granulocyte colony-stimulating factor (rhG-CSF) can accelerate granulocyte recovery after high-dose combination chemotherapy with autologous bone marrow transplantation (ABMT) in patients with Hodgkin's disease, we performed a nonrandomized phase II study using historical controls as a comparison. Eighteen relapsed/refractory Hodgkin's disease patients who received cyclophosphamide at 1.5 g/m2/day (days -6 to -3), carmustine (BCNU) at 300 mg/m2 (day -6), and etoposide (VP-16) at 125 mg/m2 every 12 hours (days -6 to -4), followed by ABMT (day 0) were treated with rhG-CSF at 60 micrograms/kg/day for a maximum of 28 days beginning on day 1. rhG-CSF dosage was gradually diminished and stopped once an adequate granulocyte count was maintained. rhG-CSF significantly accelerated absolute granulocyte count (AGC) compared with historical controls recovery to the 100/microL level (median, 9 days v 13 days; P = .103 x 10(-4), 500/microL level (median, 13 days v 22 days; P = 0.189 x 10(-2), and 1000/microL level (median, 16 days v 30 days levels; P = .125 x 10(-5). Platelet recovery to 50,000/microL was not significantly altered (P = .370). rhG-CSF was well tolerated, bone pain and myalgia being the only side effects noted. rhG-CSF hastens granulocyte recovery after high-dose chemotherapy with ABMT in patients with relapsed/refractory Hodgkin's disease without significant toxicity.

A Phase II study of recombinant granulocyte colony-stimulating factor (G-CSF) in allogeneic bone marrow transplantation (BMT) was performed. The recovery of leukocytes and neutrophils was markedly accelerated in G-CSF-administered recipients. The days to WBC count greater than 1,000/microliters (11.5 +/- 1.9) and the days to neutrophil count greater than 500/microliters (11.5 +/- 1.4) were significantly shorter than those of the monocyte-CSF (M-CSF) and CSF(-) groups. In the G-CSF group the WBC count at nadir was higher than in other groups, and neutrophil recovery preceded monocyte recovery. After the discontinuation of G-CSF, the WBC count first decreased for a few days and then increased again slowly. The short duration of leukopenia brought about a reduction in the number of febrile (greater than 38 degrees C) days which, until day 30, were 1.8 +/- 1.9 in the G-CSF group, also significantly shorter than in others. Acute graft-versus-host disease (greater than grade II) appeared in two of eight patients from the G-CSF group, this incidence being comparable to those found in the other groups. A side effect of G-CSF-mild bone pain-was observed in one patient, but it was tolerable. Six of eight patients in the G-CSF group survived for between five and 13 months after BMT with a Karnofsky score greater than 90%. No relapses were observed in the six, including one patient with chronic myelogenous leukemia and two with acute non-lymphoblastic leukemia. To determine the final influence of G-CSF on myeloid leukemia, further long-term follow-up studies are needed. G-CSF was well tolerated and seemed promising against allogeneic BMT.

The characteristics and clinical uses of recombinant colony-stimulating factors (CSFs) are described, and the pharmacist's role as a consultant and educator on biotherapeutic substances is discussed. CSFs stimulate the formation and differentiation of the erythrocytes, neutrophils, eosinophils, basophils, monocytes, and platelets that compose the blood cell population. Recombinant CSFs represent a means by which the numbers of hematopoietic cells can be modulated, thus making these agents potentially useful in treating hematologic and immunologic deficiencies. CSFs also can increase the ability of neutrophils and monocyte-macrophages to protect the body against foreign invasion. Granulocyte macrophage colony-stimulating factor (GM-CSF) has increased host defenses in acquired immunodeficiency syndrome patients with Kaposi's sarcoma; increased neutrophil, platelet, and erythrocyte counts in preleukemic patients; and increased neutrophil counts in patients with aplastic anemia. GM-CSF and granulocyte colony-stimulating factor (G-CSF) have appeared to alleviate the drastic decrease in neutrophil counts associated with cytotoxic chemotherapy. G-CSF also has shown promise in stimulating neutrophil production in patients with transitional cell carcinoma, congenital agranulocytosis, and hairy-cell leukemia. Mild adverse effects such as fever, chills, rash, fatigue, myalgia, and bone pain are associated with GM-CSF therapy; G-CSF therapy is associated mostly with mild to moderate bone pain. Areas of education for pharmacists working with biotherapeutic substances include stability, storage temperature, drug interactions, novel drug-delivery systems such as monoclonal antibodies or liposomes, variations in biologic activity, and the evolving nature of the information about these investigational drugs. The pharmacist can anticipate an increasing role as a consultant on the use of CSFs and other biotherapeutic substances.(ABSTRACT TRUNCATED AT 250 WORDS)

In patients who have not received extensive prior chemotherapy or radiotherapy, it has been previously demonstrated that granulocyte colony-stimulating factor (G-CSF) abrogated the leukopenia following administration of melphalan (25 mg/m2). This study examined the necessity of a prechemotherapy period of G-CSF administration and the effect of varying the timing and duration of postchemotherapy G-CSF. Initially, patients received 0.3, 1.0, 3.0, and 10 micrograms/kg/d subcutaneously on days 1 to 5 and days 10 to 18. Melphalan was given on day 9. In the next portion of the study melphalan was administered on day 1 and G-CSF, 10 micrograms/kg/d, was administered by subcutaneous infusion on five schedules: (1) days 2 to 13; (2) days 8 to 13; (3) days 2 to 18; (4) days 8 to 18; (5) days -9 to -2 and 2 to 13. G-CSF produced a rapid and sustained elevation in neutrophil levels within 24 hours even when started 8 days after melphalan. This treatment was sufficient to abrogate the neutropenia in patients who had received no prior chemotherapy. It was not necessary to continue G-CSF for more than 7 days. G-CSF did not consistently alter the course of the thrombocytopenia that followed this dose of melphalan. G-CSF was well tolerated, although mild bone pain occurred and was reduced with acetaminophen. One of 22 patients developed cellulitis at an infusion site. We conclude that after melphalan chemotherapy, G-CSF may need to be given for only a short period to prevent chemotherapy-induced neutropenia, and that G-CSF induces a rapid rise in neutrophil levels even when started 8 days after melphalan administration.
