Beschreibung
Inclusion Criteria:
- Aged 18-75 years, male or female.
- Histologically or cytologically confirmed stage III unresectable NSCLC per AJCC 9th edition, judged unresectable by institutional MDT team.
- Confirmed HER2 alteration: HER2 mutation/amplification detected by tissue NGS, or HER2 protein overexpression (IHC 2+ or 3+).
- No prior systemic anti-tumor therapy for NSCLC; prior anti-tumor Chinese herbal medicine allowed if ≥2 weeks washout before first dose.
- At least 1 measurable target lesion per RECIST v1.1.
- ECOG performance status 0 or 1.
- Able to provide tumor tissue specimen (archival ≤6 months or newly biopsied non-irradiated lesion).
- FEV1 >1.0 L and FEV1% predicted >40% within past 3 months.
Adequate organ function within 7 days before first dose (no blood product/G-CSF support within 14 days):
- Hematology: WBC ≥3.0×10⁹/L, ANC ≥1.5×10⁹/L, PLT ≥100×10⁹/L, Hb ≥90g/L
- Liver: AST/ALT ≤2.5×ULN (≤5×ULN for liver metastasis), TBIL ≤1.5×ULN
- Renal: Serum Cr ≤1.5×ULN or CrCl ≥50 mL/min
- Cardiac: LVEF ≥50% by echocardiogram
- Fertile male/female participants must use effective contraception during treatment and 6 months after last dose; female participants non-lactating, negative serum HCG within 14 days pre-first dose.
- Voluntarily sign written informed consent, good compliance for follow-up.
Exclusion Criteria:
- Mixed small cell/large cell neuroendocrine/sarcomatoid NSCLC histology.
- Concurrent other actionable driver gene alterations (EGFR, ALK, MET, BRAF, RET etc.) besides HER2.
- Past or concurrent other malignant tumor (except fully resected cancer ≥5 years without active treatment).
- Prior thoracic radiotherapy.
- Major surgery within 28 days or minor invasive surgery within 7 days before first dose.
- HIV infection, active hepatitis B/C, organ transplant history, congenital/acquired immunodeficiency.
- Systemic immune modulators (thymosin, interferon, IL-2) within 4 weeks pre-enrollment.
- Uncontrolled severe cardiovascular disease, unstable angina or intervention-required ventricular arrhythmia within 1 month.
- Confirmed or suspected interstitial lung disease, severe baseline pulmonary dysfunction interfering with lung toxicity monitoring.
- Active uncontrolled ≥2 grade infection within 2 weeks before enrollment.
- Active tuberculosis under treatment.
- Known hypersensitivity to any component of study drugs or other monoclonal antibodies/fusion proteins.
- Any condition judged by investigator to compromise participant safety or trial compliance.
