Evaluating befotertinib for advanced non-small cell lung cancer with specific EGFR mutations

Prospective, Multi-cohort, Single-arm Phase II Clinical Study Evaluating the Efficacy and Safety of Befotertinib in EGFR-positive Non-classical Mutant Non-small Cell Lung Cancer Patients

Phase 2 Interventional Second Affiliated Hospital, School of Medicine, Zhejiang University · NCT06863506

This study is testing a new drug called befotertinib to see if it can help people with advanced lung cancer who have specific types of EGFR mutations after other treatments haven't worked.

What this trial studies

This Phase II clinical trial investigates the efficacy and safety of befotertinib, a third-generation EGFR tyrosine kinase inhibitor, in patients with advanced or metastatic non-small cell lung cancer (NSCLC) that have non-classical EGFR mutations. The trial consists of two cohorts: one for patients with uncommon EGFR mutations (G719X, L861Q, or S768I) and another for those with EGFR exon 20 insertion mutations. The primary endpoint is the objective response rate, while secondary endpoints include disease control rate, duration of response, progression-free survival, overall survival, and safety profile. Participants must have progressed on or been intolerant to prior platinum-based chemotherapy.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with advanced or metastatic NSCLC harboring specific EGFR mutations and who have not previously received EGFR-TKI therapy.

Not a fit: Patients with active CNS metastases, severe cardiovascular disease, or those who have previously received EGFR-TKI treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new effective option for patients with specific EGFR mutations in NSCLC who currently have limited treatment choices.

How similar studies have performed: Other studies have shown promising results with similar approaches targeting EGFR mutations, indicating potential for success in this trial.
