Brief Summary

This study is a multi-cohort, open-label, multi-center exploratory clinical research designed to evaluate the efficacy and safety of Efbemalenograstim alfa Injection in preventing neutropenia (reduction in absolute neutrophil count, ANC) in solid tumor patients undergoing immune checkpoint inhibitor (ICI) combined chemotherapy. A total of 200 solid tumor patients who are scheduled to receive at least 2 cycles of ICI combined chemotherapy will be enrolled. The study is divided into three cohorts:

Cohort 1: Small cell lung cancer (SCLC) patients receiving ICI combined with chemotherapy (etoposide + carboplatin/cisplatin).

Cohort 2: Non-small cell lung cancer (NSCLC) patients receiving ICI combined with chemotherapy (platinum-based/taxane, pemetrexed/platinum).

Cohort 3: Esophageal squamous cell carcinoma (ESCC) patients receiving ICI combined with chemotherapy (TP, which stands for cisplatin + taxane).

Detailed Description

This study is a multi-cohort, open-label, multi-center exploratory clinical trial aimed at evaluating the efficacy and safety of Efbemalenograstim alfa Injection in preventing neutropenia (reduction in absolute neutrophil count, ANC) in solid tumor patients undergoing immune checkpoint inhibitor (ICI) combined chemotherapy. It plans to enroll 200 solid tumor patients who are scheduled to receive at least 2 cycles of ICI combined chemotherapy. The study is divided into three cohorts:

Cohort 1: Small cell lung cancer (SCLC) patients receiving ICI combined with chemotherapy (etoposide + carboplatin/cisplatin).

Cohort 2: Non-small cell lung cancer (NSCLC) patients receiving ICI combined with chemotherapy (platinum-based/taxane, pemetrexed/platinum).

Cohort 3: Esophageal squamous cell carcinoma (ESCC) patients receiving ICI combined with chemotherapy (TP, which stands for cisplatin + taxane).

Eligible patients will receive Efbemalenograstim alfa Injection (20 mg/dose, subcutaneous injection) 24-72 hours after the end of each chemotherapy cycle, from the 1st to the 4th cycle of ICI combined chemotherapy. Investigators must ensure that the first cycle of chemotherapy is administered at the recommended dose according to the protocol. For the 2nd to 4th cycles, dose delays or adjustments due to toxicity are allowed, and investigators may also determine the individual chemotherapy cycles and drug doses based on the patient's specific condition during these cycles. After completing 4 cycles of ICI combined chemotherapy and evaluation, patients will receive subsequent treatment according to standard clinical practice.

1. Blood routine examination criteria (without blood transfusion or blood products and without using G-CSF or other hematopoietic stimulating factors within 14 days to correct):

Hemoglobin (HB) ≥ 80g/L; Absolute neutrophil count (ANC) ≥ 1.5×109/L; Platelet count (PLT) ≥ 100×109/L;

2. Biochemical examination criteria:

Total bilirubin (TBIL) ≤ 1.5 times the upper limit of normal (ULN); Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5´ ULN; if there is liver metastasis, then ALT and AST ≤ 5´ ULN; Serum creatinine ≤ 1.5´ ULN;

3. Left ventricular ejection fraction > 50%;

• The investigator judges that the patient can tolerate the treatment with Abegrimacostat Alpha.

Exclusion Criteria

• Patients diagnosed with acute congestive heart failure, cardiomyopathy, or myocardial infarction through clinical examination, electrocardiogram, or other means;
• Individuals with a history of rubber allergy;
• Patients who have received radiotherapy for bone lesions (patients who have received radiotherapy for lesions other than bone lesions can be enrolled 4 weeks after treatment);
• Patients who have undergone bone marrow transplantation or stem cell transplantation;
• Pregnant or lactating women;
• Patients with alcoholism or drug abuse that affects their compliance in participating in the study;
• Known allergy to granulocyte colony-stimulating factors or excipients in the study drug;
• Use of other investigational drugs within 1 month prior to enrollment in this study;
• Received treatment with recombinant human granulocyte colony-stimulating factor within 6 weeks prior to enrollment;
• Presence of other primary malignancies, with the following exceptions: 1) Malignancies in complete remission for at least 2 years prior to enrollment and requiring no additional treatment during the study; 2) Non-melanoma skin cancer or malignant lentigo maligna that has been adequately treated and shows no evidence of disease recurrence; 3) Carcinoma in situ that has been adequately treated and shows no evidence of disease recurrence;
• The investigator believes that the patient has a disease or symptom that makes them unsuitable for participation in this study, or that the study drug may harm the patient's health or affect the assessment of adverse events.

• Minimum Eligible Age: 18 Years
• Eligible Sex: ALL
• Accepts Healthy Volunteers: No
