Neoadjuvant Immunotherapy Plus Chemotherapy Followed by Concurrent Chemoradiotherapy and Consolidative Immunotherapy Compared With Concurrent Chemoradiotherapy and Consolidative Immunotherapy in Locally Advanced Non-small Cell Lung Cancer: A Randomized, Phase III Controlled Study
Consolidative immunotherapy following concurrent chemoradiotherapy, based on the PACIFIC trial, has become the standard treatment for locally advanced non-small cell lung cancer (LANSCLC), leading to a 5-year survival rate of over 40%. The optimal timing of radiotherapy combined with immunotherapy still requires further exploration. This phase III, randomized controlled clinical trial is to investigate the efficacy and safety of neoadjuvant immuno-chemotherapy followed by concurrent chemoradiotherapy and consolidative immunotherapy, compared with concurrent chemoradiotherapy and consolidative immunotherapy in LANSCLC patients.
• Signed and Dated Informed Consent: Written informed consent must be provided prior to any study procedures, with the consent form signed and dated by the participant.
• Age Range: Male or female patients aged 18 to 75 years.
• Diagnosis: Patients must have locally advanced, unresectable (stage III) non-small cell lung cancer (NSCLC), with histological or cytological confirmation of the diagnosis.
• Previous Treatment: Patients must not have received prior chemotherapy, radiotherapy, surgery, targeted therapy, or immunotherapy.
• Tumor Sample Requirement: Tumor tissue samples must be provided, and they should be sufficient for analysis. The samples must be unstained and archived.
• Life Expectancy: Patients must have an expected survival of at least 12 weeks.
• Performance Status (PS): The patient's WHO Performance Status (PS) must be 0 or 1.
• Pregnancy Testing: Postmenopausal women, or women who have had a negative urine or serum pregnancy test within 14 days before the study medication (HCG sensitivity ≥ 25 IU/L or equivalent).
• Breastfeeding: Women must not be breastfeeding.
• Women of childbearing potential (WOCBP) must agree to use contraception during the study treatment period and for 5 months after the last dose of the investigational drug (i.e., 30 days \[ovulation cycle\] + approximately 5 half-lives of the study drug).
• Men who have sexual relations with WOCBP must agree to use contraception during the study treatment period and for 7 months after the last dose of the investigational drug (i.e., 90 days \[sperm renewal cycle\] + approximately 5 half-lives of the study drug).
• Males with no sperm production are exempt from contraception requirements. WOCBP who are not sexually active are exempt from contraception but must still undergo pregnancy testing as outlined above.
• Organ and Bone Marrow Function: The following laboratory parameters must be met:
⁃ Forced expiratory volume in 1 second (FEV1) ≥ 800 mL Absolute neutrophil count (ANC) ≥ 1.5 × 10⁹/L Platelets ≥ 100 × 10⁹/L Hemoglobin ≥ 9.0 g/dL Calculated creatinine clearance using the Cockcroft-Gault formula ≥ 50 mL/min Serum bilirubin ≤ 1.5 × upper limit of normal (ULN) AST and ALT ≤ 2.5 × ULN
