Phase II Clinical Study of Pyrotinib in First-line Treatment of Primary HER2-amplified/Mutated Advanced Non-small Cell Lung Cancer
Trial Parameters
Brief Summary
This is a multicenter, single-arm phase II clinical study to evaluate the safety and efficacy of pyrotinib maleate as a first-line treatment for HER2-mutated or amplified non-small cell lung cancer. Pyrotinib maleate is a small molecule tyrosine kinase inhibitor that can irreversibly inhibit HER1, HER2, and HER4.
Eligibility Criteria
Inclusion Criteria: * 1\. Age: ≥18 years old; 2. Histologically confirmed stage IIIB or IV non-small cell lung cancer; 3. Have not previously received systemic anticancer therapy for stage IIIB or IV NSCLC; 4. HER2 insertion mutation, primary HER2 point mutation or primary HER2 amplification confirmed by genetic testing of tumor tissue or blood, pleural effusion, cerebrospinal fluid and other specimens; 5. There is at least one measurable lesion determined based on RECIST 1.1; 6. ECOG score 0-1 points; 7. Expected survival period ≥ 12 weeks; 8. Cardiac ultrasound examination showed that left ventricular ejection fraction (LVEF) ≥ 50%; 9. The patient's bone marrow function, liver and kidney function were confirmed to meet the following requirements by laboratory tests before the first administration: 1.
