Filter by:The lazertinib is currently approved as 2nd line T790M mutation-positive NSCLC that failed from either 1st or 2nd generation EGFR TKI. The current recommended dosage is 240mg. Based on the promising clinical efficacy of the dose escalation study, this study is designed to evaluatee the clinical efficacy and safety of 160mg lazertinib.
Liquid biopsy is emerging as an essential tool in tumor monitoring and a potential alternative and supplement to tissue biopsy for tumor genotyping, especially in relapsed or metastatic diseases. Liquid biopsy methods for detecting T790M in ctDNA can be qualitative or quantitative, including amplification refractory mutation system PCR (ARMS-PCR), digital droplet polymerase chain reaction (ddPCR), and next generation sequencing (NGS)-based methods. Comparison of multiple detecting platform for EGFR mutations in plasma samples has been undertaken in studies to determine the most feasible assay in clinical practice. In this study, we will investigate the usefulness of ddPCR for quantitative detection of EGFR T790M mutation in peripheral blood, and compared the utility of ddPCR and NGS for guiding decisions regarding osimertinib therapy in NSCLC patients who had develop resistance to first- or second generation EGFR-TKIs.
- It is to evaluate the safety and effectiveness of a lasertinib(LECLAZA) single drug in a actual medical environment for patients 1. Primary Purpose: Progression-free survival (PFS) 2. Secondary Purpose: - Objective response rate - Time to treatment failure - Adverse event (AE), serious adverse event (SAE), and adverse event of special interest (AESI) - Severity of (S)AE - duration of response (DoR) - Overall survival (OS) - Intravenous Progressive Survival Period (Intracranial PFS) - Relative dose intensity - Research Design : a Multi-Center Prospective and Restrospective Cohort Study
This is a Phase 1/2, open-label, first-in-human (FIH) study designed to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and anticancer activity of BLU-945, a selective EGFR inhibitor, as monotherapy or in combination with osimertinib.
Almonertinib Plus Pemetrexed and Carboplatin Versus Almonertinib Alone in Advanced NSCLC With EGFR T790M After First- or Second-generation TKIs Therapy: a Randomized, Controlled, Open-label, Phase 2 Study
A Phase II, Open Label, Single-arm Study to Assess the Safety and Efficacy of D-0316 in Patients with Locally Advanced/Metastatic Non Small Cell Lung Cancer whose Disease has Progressed with Previous Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor Therapy and whose Tumours are Epidermal Growth Factor Receptor Mutation and T790M Mutation Positive
This is a single arm, open label, multicentric proof-of-concept, phase II study in patients with EGFR-mutated non-small-cell lung cancer (NSCLC) with acquired TKI resistance who are "unknown" for EGFR T790M status due to non-informative or unfeasible tumor rebiopsy, and a negative finding for EGFR T790M in a standard plasma genotyping assay. All patients will receive osimertinib as continuous oral treatment for one cycle (28 days). Patients who demonstrate a metabolic response by FDG-PET scanning (to be conducted between day 15 and day 28 of cycle 1) will continue treatment until clinical or radiological progression. Osimertinib treatment will be terminated in patients not experiencing a metabolic response. Primary objective: To study the rate of early metabolic responses to osimertinib in patients with EGFR-mutated NSCLC and acquired TKI resistance who are "unknown" for EGFR T790M status due to non-informative or unfeasible tumor rebiopsy, and a negative finding for EGFR T790M in a standard plasma genotyping assay.
The third generation epidermal growth gactor receptor-tyrosine Kinase Inhibitor(EGFR-TKI) osimertinib has obvious curative effect for EGFR sensitive mutation and T790M mutation(PMID 27959700), but acquired drug resistance will occur. Previous studies show that apoptosis escape can lead to EGFR-TKI resistance.Osimertinib resistant cells show abnormal activation of PI3K/AKT/BIM activation(PMID 28765329). The classical drug aspirin can effectively decrease AKT phosphorylation and activate of BIM(PMID 28881293).So Investigators speculate that aspirin may decrease the PI3K/AKT/BIM signaling pathways, then promote osimertinib resistant cells apoptosis. The current study aims to evaluate the combination of aspirin and osimertinib in patients with EGFR/T790M mutations.
