Electroacupuncture Combined With PD-1 Inhibitor for Elderly Patients With Advanced NSCLC

Summary

The goal of this clinical trial is to elucidate the clinical efficacy and safety of electroacupuncture combined with PD-1 inhibitor therapy in elderly patients with advanced non-small cell lung cancer (NSCLC) through a multicenter, randomized controlled clinical trial. The main question it aims to answer is: the combination of electroacupuncture and PD-1 inhibitor therapy has demonstrated significant improvements in both clinical efficacy and safety profiles among elderly patients with advanced NSCLC. Researchers will compare a sham electroacupuncture group combined with PD-1 inhibitor therapy (serving as the control group) to see if the intervention group exhibits superior therapeutic efficacy and safety outcomes. Participants will be randomly assigned to one of two groups: an electroacupuncture combined with an immune checkpoint inhibitor group, or a sham electroacupuncture combined with an immune checkpoint inhibitor group. The immune checkpoint inhibitor will be administered on a 21-day cycle, with a total of 4 to 6 treatment cycles, followed by the option for maintenance therapy. Electroacupuncture treatment will commence on the same day as the initiation of the immune checkpoint inhibitor cycle, administered once daily for a total of five sessions per cycle, with 4 to 6 cycles in total. The primary outcome measure is progression-free survival (PFS). Secondary outcomes include objective response rate (ORR), quality of life, immune function, traditional Chinese medicine syndrome scores for lung cancer, and safety parameters. This study aims to establish the efficacy and safety of electroacupuncture combined with PD-1 inhibitors in elderly patients with advanced NSCLC. Additionally, peripheral non-coding RNA will be collected at baseline to analyze differentially expressed genes, thereby identifying molecular predictive biomarkers for patients who may benefit most from this combined treatment approach.

Eligibility

Inclusion Criteria:

* Patients with stage IIIB-IV non-small cell lung cancer (NSCLC) confirmed by histopathological or cytological diagnosis.
* Patients with negative driver gene mutations, as determined by genetic testing or other molecular biological methods, to exclude common driver mutations such as EGFR mutations and ALK rearrangements.
* Patients aged ≥65 years, with consideration for the patients' overall physical condition. Additional assessments will be conducted if there are comorbidities or other factors that may affect their physical status.
* PD-L1 tumor proportion score (TPS) ≥1%.
* Estimated survival time \>3 months, as determined by clinical evaluation based on the patient's overall condition, tumor progression, and response to treatment.
* ECOG performance status score of 0-2.
* Patients with good treatment compliance, who are willing to sign an informed consent form, indicating their understanding and agreement to adhere to the study protocol for treatment and follow-up.

Exclusion Criteria:

* Patients with a history of or concurrent other malignancies within the past 5 years.
* Patients with severe organ dysfunction or other serious comorbidities, such as heart failure (NYHA Class III-IV), hepatic or renal insufficiency, as assessed by routine examinations including liver function tests, renal function tests, and electrocardiograms.
* Patients with untreated central nervous system metastases. Only those who have undergone at least one course of systemic or surgical treatment and have been confirmed to have stable disease by imaging studies will be included.
* Patients with psychiatric disorders, including a history of severe mental illnesses (e.g., schizophrenia, bipolar disorder) that require pharmacological treatment for control.
* Patients with a history of multiple drug allergies or an allergic constitution, particularly those who have experienced severe allergic reactions such as anaphylactic shock or allergic rashes.
* Patients with active autoimmune diseases or infectious diseases, including but not limited to active or chronic viral hepatitis, active pulmonary tuberculosis, or other infectious or autoimmune conditions deemed by the clinical investigator to potentially affect the study.
* Patients who are pregnant or breastfeeding.
