EGFR Positive Non-small Cell Lung Cancer

An Open-label, Single-arm, Phase II Clinical Study of Firmonertinib in Perioperative Treatment of Resectable Stage II-IIIB EGFR-mutated Lung Adenocarcinoma

This study evaluates the efficacy and safety of Firmonertinib 160 mg once daily in patients with EGFR-mutant, advanced NSCLC who achieve stable disease after first-line Firmonertinib 80 mg for 8 weeks.

Osimertinib combined with savolitinib in the treatment of EGFR mutated osimertinib resistant NSCLC with low copy number MET amplification There are unmet medical needs in patients who resist to to osimertinib; savolitinib plus osimertinib shows high response rate and prolong progression-free survival in high copy number MET amplification patients. This study is to explore the efficacy and safety of the combination of savolitinib and osimertinib in osimertinb resistant patients with low copy number MET amplification.

The goal of this study is to develop and test the feasibility of a supportive care model (POISE) for patients with metastatic Non-small Cell Lung Cancer (NSCLC). The main questions are * is POISE feasible to deliver and acceptable to patients * what is the effect of POISE on the distress patients feel related to their uncertain future, their confidence in their ability to manage cancer, and their understanding about what to expect Participants in the randomized controlled trial will receive either the new supportive care model, POISE, which consists of four visits with a trained palliative care clinician, or care as usual, and will be asked to complete three surveys.

Lung cancer is the leading cause of cancer incidence (11.6%) and mortality (18.4%) globally\[1\]. Development of targeted therapies in the context of precision medicine changed the way lung cancer was diagnosed and treated. Small molecule inhibitors, like tyrosine kinase inhibitors (TKIs), are now standard first-line therapy for EGFR-positive non-small cell lung cancer (NSCLC). First-generation EGFR-TKIs gefitinib and erlotinib bind competitively to the ATP-binding site of EGFR TK domain. This binding in second-generation TKI afatinib is irreversible. These drugs have improved better outcome compared to standard conventional chemotherapy In spite of this, more than half of the patients with an EGFR TKI treatment develop resistance. Deletion in exon 19 and single point substitution L858R in exon 21 accounting for 44% and 41% of all EGFR mutations, respectively are the most common mutations in EGFR gene which cause this resistance in the patients. Asia has the highest prevalence of EGFR mutations (38.4%), followed by America (24.4%) and Europe (14.1%). Median progression-free survival of EGFR mutated NSCLC patients under erlotinib or gefitinib has been around 12 months and 5-year survival was 15%

This study was designed to investigate the efficacy and safety of neoadjuvant Toripalimab (anti-PD1) plus chemotherapy for patients with resectable II-IIIB non-squamous NSCLC harboring EGFR mutation, and to explore the potential predictive and prognostic biomarkers, aiming to provide more abundant evidences for the preoperative treatment decision of non-squamous NSCLC patients.
