Overview

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.

Randomized Clinical Trial on Xingbaiji Formula Combined with Chemotherapy and Sintilimab as First-Line Treatment for Recurrent/Metastatic Stage IIIB-IV EGFR/ALK/ROS-1 Mutation-Negative Non-Small Cell Lung Cancer Primary Objective: To evaluate efficacy by measuring Objective Response Rate (ORR) in patients receiving Xingbaiji Formula combined with chemotherapy and Sintilimab. Secondary Objectives: To assess Progression-Free Survival (PFS), Quality of Life (QoL), immune-related biomarkers, safety, and adverse event rates. Study Arms Control Group Non-squamous NSCLC: Sintilimab 200mg + Pemetrexed + Cisplatin/Carboplatin (IV, Q3W for 4 cycles). After induction, maintenance with Sintilimab 200mg Q3W (≤24 months) + Pemetrexed Q3W until disease progression, toxicity, or withdrawal. Squamous NSCLC: Sintilimab 200mg + Gemcitabine + Cisplatin/Carboplatin (IV, Q3W for 4-6 cycles). Maintenance with Sintilimab 200mg Q3W until progression or maximum 2 years. Experimental Group Control Regimen + Xingbaiji Formula: Xingbaiji Granule 1 (10g/sachet): Dissolved in warm water, 1 sachet twice daily (morning/evening, post-meal). Xingbaiji Granule 2 (5g/sachet): Dissolved in warm water, 1 sachet twice daily (morning/evening, post-meal). Duration: Concurrent with chemotherapy for 6 months, then discontinued.

Patients were randomized into two groups: Control Group: Non-squamous NSCLC: Sintilimab (200 mg) combined with pemetrexed + cisplatin/carboplatin, administered intravenously (IV) every 3 weeks (Q3W) for 4 cycles. After 4 cycles, maintenance therapy with sintilimab (200 mg Q3W, up to 24 months) + pemetrexed Q3W continued until disease progression, intolerable toxicity, death, or voluntary withdrawal. Squamous NSCLC: Sintilimab (200 mg) combined with gemcitabine + cisplatin/carboplatin, IV Q3W for 4-6 cycles. Post-induction, sintilimab (200 mg Q3W) maintenance continued until progression, intolerance, or ≤2 years of treatment. Experimental Group: The control regimen plus Xingbaiji Formula: Xingbaiji Granule 1: 10 g/bag, dissolved in warm water, 1 bag twice daily (morning and evening) after meals. Xingbaiji Granule 2: 5 g/bag, dissolved in warm water, 1 bag twice daily (morning and evening) after meals.

Inclusion Criteria: 1. Signed written informed consent. 2. Age: 18-75 years, regardless of gender. 3. Histologically or cytologically confirmed non-small cell lung cancer (NSCCC), including adenocarcinoma, squamous cell carcinoma, or large cell carcinoma, with negative EGFR, ALK, and ROS-1 mutations confirmed by next-generation sequencing (NGS). Stage IIIB-IV NSCLC as per AJCC 8th edition staging criteria (required evaluations: neck contrast-enhanced CT or ultrasound, chest contrast-enhanced CT, abdominal contrast-enhanced CT or ultrasound, brain contrast-enhanced MRI, bone scan, or whole-body PET/CT). 4. ECOG performance status ≤2 and life expectancy ≥3 months. 5. Histologically or cytologically documented ineligibility for EGFR, ALK, or ROS-1 targeted therapies (written evidence required). 6. At least one measurable lesion per RECIST v1.1. Lesions within prior radiation fields or post-local treatment may be selected if progression is confirmed. 7. No prior systemic anti-tumor therapy for advanced disease. Adjuvant chemotherapy is permitted if ≥6 months have elapsed between recurrence and the last dose. Exclusion Criteria: 1. History of or concurrent other malignancies (excluding non-invasive tumors such as cured basal cell carcinoma of the skin, cervical carcinoma in situ, etc.); 2. Individuals with allergic reactions to the Xingbaiji formula; 3. Patients with mixed small cell lung cancer or those with a small cell lung cancer component; 4. Severe mental illness or cognitive impairment that would impede compliance with study protocols or follow-up requirements; 5. Pregnant or lactating women (a pregnancy test must be performed to exclude pregnancy; women of childbearing age must agree to use effective contraception during the study); 6. Presence of any major illness or significant laboratory abnormalities that may interfere with receiving Xingbaiji formula, chemotherapy, or immunotherapy; 7Any other conditions deemed by the investigators to render participation in the trial inappropriate.
