Phase 3 Trial Comparing Oral Sevabertinib to Standard Infusion Therapy as First Treatment for Advanced Non-Squamous Non-Small Cell Lung Cancer with HER2 Mutations

What this Trial Is About

Researchers are evaluating treatments for people with advanced non-small cell lung cancer NSCLC that have specific genetic changes called HER2 mutations. This lung cancer has spread or cannot be controlled with current treatments. The study aims to compare how well a drug called sevabertinib works and how safe it is compared to standard treatment for this type of cancer. Participants will receive either sevabertinib tablets twice daily or standard treatment consisting of pembrolizumab combined with platinum-based chemotherapy given every 21 days by infusion. Those on standard treatment who experience disease progression may switch to sevabertinib. Treatment continues as long as participants benefit and do not have severe side effects or until they or their doctor decide to stop. During the study, participants will have imaging scans like CT, PET, MRI, and X-rays to monitor cancer spread. Doctors will also perform health checks including blood and urine tests, heart monitoring with ECG, pregnancy tests for women, and ask about symptoms or side effects. The main measure is progression-free survival assessed up to about 2 years, with additional outcomes related to survival, response rates, side effects, and quality of life followed up to 4 years.
