Filgrastim is a water-soluble 175 amino acid protein with a molecular weight of approximately 19 kilodaltons. Filgrastim is obtained from the bacterial fermentation of a strain of Escherichia coli transformed with a genetically engineered plasmid containing the human GCSF gene. To produce pegfilgrastim, a 20 kDa monomethoxypolyethylene glycol molecule is covalently bound to the N-terminal methionyl residue of filgrastim. The average molecular weight of pegfilgrastim is approximately 39 kDa.<\/p>\n
Each Syringe contains 6 mg Pegfilgrastim (based on protein weight) in a sterile, clear, colorless, preservative-free solution. The pH of the solution is 4.0.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=”Composition” tab_id=”1593171293788-0816dcbf-f99f”][vc_column_text]Each prefilled syringe of 0.6 ml contains:<\/p>\n

In this test, both the test and reference drugs were found comparable and equipped. Pharmacokinetic studies were done in nonneutropenic rat and compared with the reference standard. The halflives of the product were comparable to that of the reference standard.<\/p>\n
Acute toxicity studies were conducted in rats and mice by administering I.V. and S.C. single doses of 1000, 5000, and 10000 mcg\/Kg of Pegfilgrastim. The animals were observed for mortality, clinical signs, and gross organ examinations. There was no death or any other adverse effect on the animals at all the dose levels. In repeat-dose subacute toxicity studies in rats, mice and rabbits a dose of 100, 500 and 1000 mcg\/Kg were administered for a period of 28 days by SC and IV routes. The animals were examined for body weight changes, food consumption, blood chemistry, and histopathological examination of body organs. There was no abnormality detected in any of the parameters in the animals. Pegfilgrastim was well tolerated in low, medium, and high dose levels.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=”Mechanism of Action” tab_id=”1584624217032-a15849ed-97bb”][vc_column_text]Pegfilgrastim is a pegylated recombinant human granulocyte colony stimulating factor that acts on hematopoietic cells by binding to specific cell surface receptor thereby stimulating proliferation, differentiation, commitment and end cell function activation. Studies on cellular proliferation, receptor binding and neutrophil function demonstrate that pegfilgrastim has mechanism of action similar to its patent drug filgrastim. Pegfilgrastim has reduced renal clearance and prolonged persistence in vivo as compared to filgrastim.[\/vc_column_text][vc_column_text][\/vc_column_text][\/vc_tta_section][vc_tta_section title=”Pharmacokinetics” tab_id=”1584624217050-ebb8ae5e-43a6″][vc_column_text]The pharmacokinetics of pegfilgrastim is nonlinear in cancer patients and clearance decreases with increase in the doses. Neutrophil receptor binding is an important component of the clearance of pegfilgrastim and serum clearance is directly related to the number of neutrophils. The concentration of pegfilgrastim declines rapidly at the onset of neutrophil recovery that follows myelosuppression chemotherapy. Additionally, patients with higher body weights experience higher systemic exposure of pegfilgrastim after receiving a dose normalized for body weight. A large variability in the pharmacokinetics of pegfilgrastim has been observed in cancer patients. The half life of pegfilgrastim ranges from 15 to 80 hours after subcutaneous injection.[\/vc_column_text][vc_column_text][\/vc_column_text][\/vc_tta_section][vc_tta_section title=”Indications” tab_id=”1584624459062-96fb7e5b-0e23″][vc_column_text]Pegfilgrastim is indicated to decrease the incidence of infection, as manifested by febrile neutropenia, in patients with non-myeloid malignancies receiving myelosuppressive anticancer drugs associated with a clinically significant incidence of febrile neutropenia[\/vc_column_text][vc_column_text][\/vc_column_text][\/vc_tta_section][vc_tta_section title=”Dosage & Administration” tab_id=”1584624839401-59481bbb-bdc7″][vc_column_text]The recommended dosage of pegfilgrastim is a single subcutaneous injection of 6 mg administered by subcutaneous route once per chemotherapy cycle.

The 6 mg fixed-dose formulation should not be used in infants, children, and smaller adolescents weighing less than 45 kg. No dosing adjustment is necessary for renal dysfunction. Pegfilgrastim should be visually inspected for discoloration and particulate matter and if found, should not be administered.[\/vc_column_text][vc_column_text][\/vc_column_text][\/vc_tta_section][vc_tta_section tab_id=”1584625017135-3ffdd9c5-1bd6″ title=”Warnings”][vc_column_text]General<\/strong><\/p>\n The safety and efficacy of pegfilgrastim for peripheral blood progenitor cell (PBPC) mobilization has not been evaluated. Pegfilgrastim should not be used for PBPC mobilization.<\/p>\n Splenic Rupture<\/strong><\/p>\n Splenic rupture, including fatal cases, has been reported following the administration of pegfilgrastim and its parent compound, filgrastim. Patients receiving pegfilgrastim who report left upper abdominal and\/or shoulder tip pain should be evaluated for an enlarged spleen or splenic rupture.<\/p>\n Adult Respiratory Distress Syndrome (ARDS)<\/strong><\/p>\n Adult Respiratory Distress Syndrome (ARDS) has been reported in patients receiving pegfilgrastim and is postulated to be secondary to an influx of neutrophils to sites of inflammation in the lungs. Neutropenic patients receiving pegfilgrastim who develop fever, lung infiltrates or respiratory distress should be evaluated for the possibility of ARDS. In the event that ARDS occurs, pegfilgrastim should be discontinued and\/or withheld until resolution of ARDS, and patients should receive appropriate medical management for this condition.<\/p>\n Allergic reaction<\/strong><\/p>\n Allergic reactions to pegfilgrastim, including anaphylaxis, skin rash, and urticaria have been reported in post-marketing experience. If a serious allergic reaction occurs, appropriate therapy should be administered with close patient follow-up over several days. Pegfilgrastim should be permanently discontinued in patients with serious allergic reactions.<\/p>\n Sickle Cell Disease<\/strong><\/p>\n Severe sickle cell crises have been associated with the use of pegfilgrastim in patients with sickle cell disease. Severe sickle cell crises, in some cases resulting in death, have also been associated with filgrastim, the parent compound of pegfilgrastim. The only physician qualified by specialized training or experience in the treatment of patients with sickle cell disorders should prescribe Pegfilgrastim should be used with caution in patients with sickle cell disease, and only after careful consideration of the potential risks and benefits.[\/vc_column_text][vc_column_text][\/vc_column_text][\/vc_tta_section][vc_tta_section title=”Precautions” tab_id=”1588004155234-9eb27d85-6ba1″][vc_column_text]Use with chemotherapy and \/ or radiation therapy<\/strong><\/p>\n Pegfilgrastim should not be administered in the period between 14 days before and 24 hours after administration of cytotoxic chemotherapy because of the potential for an increase in sensitivity of rapidly dividing myeloid cells to cytotoxic chemotherapy. The use of pegfilgrastim has not been studied in patients receiving chemotherapy associated with delayed myelosuppression (e.g. Nitrosourea, Mitomycin C). The administration of pegfilgrastim concomitantly with 5fluorouracil or other antimetabolites has not been evaluated in patients. Administration of pegfilgrastim at 0, 1 and 3 days before 5fluorouracil results in increased mortality in mice: administration of pegfilgrastim 24 hours after 5fluorouracil did not adversely affect survival. The use of pegfilgrastim has not been studied in patients receiving radiation therapy.<\/p>\n Potential for tumour growth stimulating effects on malignant cells<\/strong><\/p>\n The granulocyte colony stimulating factor (GCSF) receptor through which pegfilgrastim and filgrastim act has been found on tumor cell lines. The possibility that pegfilgrastim acts as a growth factor for any tumor type, including myeloid malignancies and myelodysplasia, disease for which pegfilgrastim is not approved, cannot be excluded.<\/p>\n Laboratory Monitoring<\/strong><\/p>\n To assess the patient’s hematologic status and ability to tolerate Myelosuppressive chemotherapy, a complete blood count and platelet count should be obtained before chemotherapy is administered. Regular monitoring of hematocrit value and platelet count is recommended.<\/p>\n Carcinogenesis, Mutagenesis & Impairment of Fertility<\/strong><\/p>\n No mutagenesis studies were conducted with pegfilgrastim. The carcinogenic potential of pegfilgrastim has not been evaluated in long term animal studies. In toxicity studies of 6 months duration in rats given once weekly subcutaneous injections of upto 1000 mcg\/Kg of pegfilgrastim, no precancerous or cancerous lesions were noted. When administered once weekly via subcutaneous injections to male and female rats at dose upto 1000 mcg\/Kg prior to, during mating, reproductive performance, fertility and sperm assessment parameters were not affected.<\/p>\n USE IN SPECIAL POPULATIONS<\/strong><\/p>\n Pregnancy<\/strong><\/p>\n Pregnancy Category C<\/strong><\/p>\n There are no adequate and wellcontrolled studies in pregnant woman. Pegfilgrastim should be used during pregnancy only if potential benefit to the mother justifies the potential risk to the fetus.<\/p>\n Nursing mothers<\/strong><\/p>\n It is not known whether pegfilgrastim is secreted in human milk.

The other common undesirable effects include vomiting, headache, anemia, constipation, fatigue, diarrhea, general weakness, mucositis, neutropenia, fever, body pain, taste alteration, alopecia, anorexia, skeletal pain, asthenia, pyrexia, dyspepsia, myalgias, insomnia, abdominal pain, arthralgias, peripheral edema, dizziness, granulocytopenia, stomatitis, and neutropenic fever. Leukocytosis (WBC counts > 100 X 109\/L) is observed in less than 1% of patients with nonmyeloid malignancies receiving pegfilgrastim. Leukocytosis is not associated with any adverse effects.<\/p>\n Immunogenicity<\/strong><\/p>\n The incidence of antibody development in patients receiving pegfilgrastim has not been adequately determined. While available data suggest that a small proportion of patients developed binding antibodies to filgrastim or pegfilgrastim, the nature and specificity of these antibodies have not been adequately studied.<\/p>\n Cytopenias resulting from an antibody response to exogenous growth factors have been reported on rare occasions in patients treated with other recombinant growth factors. There is a theoretical possibility that an antibody directed against pegfilgrastim may crossreact with endogenous GCSF, resulting in immune-mediated neutropenia, but this has not been observed in clinical studies of pegfilgrastim.<\/p>\n The experimental data obtained from the post-marketing surveillance study showed that none of the patients were observed to develop any immunogenic response according to the specified screening cut-point criteria. It was concluded that in this study none of the patients showed antipeg GCSF antibody development against pegfilgrastim.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=”Drug Interactions” tab_id=”1588004246143-da131a40-78a3″][vc_column_text]No formal drug interaction studies between pegfilgrastim and other drugs have been performed. Drugs such as lithium may potentiate the release of neutrophils\u037e patients receiving pegfilgrastim and lithium should have more frequent monitoring of neutrophil counts.
