The study population includes children with cancer who require high-intensity chemotherapy. The study aims to evaluate the safety and effectiveness of Telpegfilgrastim in preventing neutropenia in children with cancer (neuroblastoma, sarcoma, lymphoma, etc.) undergoing chemotherapy, while also studying the pharmacokinetic characteristics of Telpegfilgrastim in children with cancer.', 'detailedDescription': 'Compared with the currently available straight chain PEG-rhG-CSF, the structure of its Y-type branch chain affects the activity and metabolic rate of the drug to a certain extent. While prolonging the half-life of the drug, the dosage of the drug is also significantly lower than that of the long-acting products on the market. It can be prophylactically administered once after chemotherapy to maintain the effective blood concentration of the whole cycle and effectively prevent the occurrence of neutropenia. Due to the reduction of the dose, the incidence of side effects such as musculoskeletal pain is correspondingly reduced, and there may be a better safety. At the same time, the accessibility of clinical PEG-rhG-CSF can be further solved, and the treatment cost is also expected to decrease, so that more patients can benefit from PEG-rhG-CSF.\n\nTelpegfilgrastim was approved on June 30, 2023 for "reducing the incidence of infection characterized by febrile neutropenia in patients with non-myeloid malignants who are treated with myelosuppressive anticancer agents that tend to cause clinically significant febrile neutropenia." At present, although Telpegfilgrastim has been approved for neutropenia induced by chemotherapy for non-myeloid malignant tumors, the safety and efficacy data in pediatric patients are lacking, and the pharmacokinetic characteristics in children are still unclear. The aim of this study was to evaluate the safety and efficacy of Telpegfilgrastim in the prevention of neutropenia in pediatric cancer patients receiving chemotherapy, and to investigate the pharmacokinetics of Telpegfilgrastim in pediatric cancer patients.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT'], 'maximumAge': '18 Years', 'minimumAge': '14 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Patients with 14≤ age \\< 18 years;\n\n * Newly diagnosed patients with non-myeloid malignancies who are confirmed by histopathology or cytology to require intensive chemotherapy (first course of chemotherapy or second course of chemotherapy);\n\n * Primary prevention (G-CSF 24 to 72 hours after the first use of chemotherapy agents with myelosuppression to prevent the occurrence of febrile neutropenia (FN)) or secondary prevention (if FN or dose-restricted neutropenia occurred in a patient during a previous chemotherapy cycle) is required.
