Clinical Trial Protocol
Primary Objective:
To evaluate the efficacy of the Xingbaiji Formula combined with chemotherapy and Sintilimab as first-line therapy in patients with recurrent or metastatic Stage IIIB-IV EGFR/ALK/ROS-1 mutation-negative non-small cell lung cancer (NSCLC), using Objective Response Rate (ORR) of tumor lesions as the primary endpoint.
Secondary Objectives:
To assess secondary endpoints including Progression-Free Survival (PFS), Quality of Life (QoL), immune-related indicators, and safety profile (e.g., incidence of adverse events), and to further evaluate the efficacy and safety of the combination therapy.
Randomized Group Allocation:
Participants will be randomly assigned to two groups:
Control Group
Regimen for Advanced Non-Squamous NSCLC:
Drugs and Dosage:
Sintilimab 200mg + Pemetrexed + Cisplatin/Carboplatin via intravenous infusion, administered every 3 weeks (Q3W) for 4 cycles.
After completion of 4 cycles, patients enter the maintenance phase: Sintilimab 200mg Q3W (up to 24 months) + Pemetrexed Q3W until disease progression, intolerable toxicity, death, or voluntary withdrawal.
Regimen for Advanced Squamous NSCLC:
Drugs and Dosage:
Sintilimab 200mg + Gemcitabine + Cisplatin/Carboplatin via intravenous infusion, Q3W for 4-6 cycles.
Post-treatment, patients receive Sintilimab 200mg Q3W maintenance until disease progression, intolerability, or completion of 2 years of Sintilimab therapy.
Experimental Group Control Group Regimen + Xingbaiji Formula
Xingbaiji Formula Dosage:
1. Granule No. 1: 10g/bag, dissolved in warm water. Administration: 1 bag orally, twice daily (morning and evening), after meals. 2. Granule No. 2: 5g/bag, dissolved in warm water. Administration: 1 bag orally, twice daily (morning and evening), after meals. Treatment Duration: Both granules are taken concurrently with chemotherapy for 6 months, then discontinued.
