Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

EGFR mutation positive advanced NSCLC patients with uncleared ctDNA have poor prognosis, whether they can benefit from combination therapy has not been reported. This study aims to investigate the efficacy and safety of combination therapy compared with furmonertinib monotherapy in advanced EGFR mutant NSCLC with uncleared circulating tumor cell DNA.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a prospective, multicenter, randomized, open label, clinical study in China.

In total the study aims to screen 720 patients and enroll approximately 280 advanced NSCLC patients with EGFR mutation positive circulating tumor cell DNA, consisting of 47 patients whose ctDNA is cleared after 3 weeks furmonertinib will receive furmonertinib monotherapy, and approximately 233 patients with uncleared ctDNA after 3weeks furmonertinib monotherapy will receive furmonertinib alone or furmonertinib in combination with chemotherapy or furmonertinib in combination with chemotherapy and bevacizumab in the main trial. In the main part of the trial, for the approximately 233 patients with uncleared ctDNA, there are 2 / 2 / 1 in 5 chances of receiving furmonertinib alone, furmonertinib plus chemotherapy, or furmonertinib plus chemotherapy and bevacizumab. The treatment is decided at random by a computer.

The study involves a Screening Period, Induction treatment period, Treatment Period, and Follow up Period. Whilst receiving study medication, it is expected patients will attend, on average, approximately 9 visits. Each visit will last about 2 to 6 hours depending on the arrangement of medical assessments by the study site.
