Filter by:Osimertinib, though a standard first-line treatment for EGFR-mutant advanced NSCLC, shows primary resistance in 10-30% of patients, leading to disease progression within 3-4 months. This resistance is linked to co-mutations in genes like TP53, RB1, and PIK3CA, among others. Studies indicate that Topo II inhibitor Etoposide (VP-16) can reduce cell survival, enhance DNA damage, and delay resistance in Osimertinib-resistant cells, suggesting a potential combination therapy to manage resistance.This study is a single-center, prospective, single-arm study evaluating the efficacy and safety of osimertinib combined with etoposide as a first-line treatment in patients with osimertinib-resistant or -insensitive advanced non-small cell lung cancer (NSCLC). The study focuses on patients with advanced NSCLC (stage IIIB or IV) with EGFR-sensitive mutations who developed slow resistance to osimertinib and for whom secondary biopsy after resistance did not identify any therapeutic targets.
This study plans to conduct ctDNA testing on EGFR mutation-positive stage II-IIIA (N1-N2) NSCLC patients after radical surgery (R0 resection). Patients with positive ctDNA testing will receive standard treatment according to clinical guidelines, while patients with negative ctDNA testing will be assessed based on comprehensive clinical and pathological characteristics. After receiving or not receiving standard adjuvant chemotherapy, patients will be randomly assigned in a 1:1 ratio to either the observation follow-up group (experimental group) or the osimertinib adjuvant treatment group (control group). The aim is to explore whether observation follow-up for patients with negative ctDNA after surgery has a prognosis non-inferior to osimertinib treatment, and to investigate the disease-free survival rate of EGFR mutation-positive stage II-IIIA (N1-N2) NSCLC patients with positive ctDNA after surgery receiving osimertinib adjuvant treatment, providing more precise treatment guidance for adjuvant therapy in this specific type of NSCLC patients with EGFR mutation-positive tumors.
Activity of patritumab deruxtecan (U3-1402; HER3-DXd) has been shown in a phase I/II study in patients with HER3 expressing breast cancer as well as in a phase I study in patients with EGFR TKI refractory EGFR mutation positive NSCLC with a preliminary ORR of 25%. HER3 expression can be seen in multiple tumor types and is therefore an attractive target for antibody drug conjugate (ADC) treatment. However, intra- and intertumor heterogeneity of HER3 expression might be substantial, as is seen for HER2, and might contribute to treatment failure or heterogeneous responses. In addition, HER3 expression is dynamic and has been shown to change over time. In order to identify patients that may benefit most from treatment with patritumab deruxtecan, better knowledge of the in vivo behaviour of the drug is warranted. One way to visualize this behaviour is positron emission tomography (PET) imaging with radiolabelled antibodies (immune-PET). 89Zr-Patritumab deruxtecan PET/CT can assess HER3 expression non-invasively at a whole body level, including sites that may be difficult to biopsy. It also visualizes and quantifies biodistribution of patritumab deruxtecan, thereby obtaining valuable information for safety and toxicity analyses.
This study is a single-center, prospective, single-arm study of the efficacy of double-dose Furmonertinib in the treatment of patients with slow Osimertinib-resistant non-small cell lung cancer, mainly in patients with advanced non-small cell lung cancer with EGFR-sensitive mutations in stage IIIB or IV, slow drug resistance after treatment with Osimertinib, and no therapeutic target was found by secondary biopsy after drug resistance.
The purpose of this study is to evaluate the efficacy and safety of Nintedanib with EGFR-TKI in participants with advanced EGFR-TKI-resistant non-small cell lung cancer
This is a single-center, prospective, single-arm, phase II study of Osimertinib combined with Aspirin neoadjuvant therapy for resectable, EGFR mutated non-small cell lung cancer (NSCLC). It is mainly aimed at the population of patients with primary IIA- IIIA EGFR sensitive mutations that are intended to be treated with Osimertinib neoadjuvant therapy.
Low intensity, intermediate frequency (100-300 kHz) alternating electric fields, also known as Tumor Treating Fields (TTFields) were found to have a profound inhibitory effect on the growth rate of a variety of human cancer cells. Previous study showed anti-tumor activity in respect of melanoma, glioblastoma (GBM), breast carcinoma and NSCLC cell lines. This study aims to assess the impact of TTFields on NSCLC though the understanding of tumor evolution and peripheral lymphocytes activity and proliferation. Concomitant to drug therapy, patients will receive treatment with Tumor Treating Fields (TTFields), generated by the medical device NovoTTF-200T with a recommended duration of minimum 18 h a day. TTFields administered using insulated transducer arrays applied to the skin surrounding the region of a malignant tumor. 50 patients will be recruited according to the study design in two cohorts and will receive TTFields therapy: Cohort A: Adult NSCLC EGFR positive mutation. Cohort B: Adult NSCLC patients to be treated with PD-1 inhibitors. The cohort A will focus on the clonal evolution in EGFR mutated lung cancer patients by using circulating tumor DNA (ctDNA) analysis of paired baseline and end-of-treatment (EOT) plasma samples. The cohort B will study the impact of TTField on the profile, activity, and proliferation of peripheral lymphocytes. Lymphocytes will be purified from whole blood samples for the profile, proliferation, and activity analyzed by FACS. Treatment with TTFields will be administered until progressive disease, unacceptable toxicity1, withdrawal of consent or death. After the end of treatment, the patients will be followed until data cutoff date or 2 years after the last patient had entered the study.
A study to evaluate the efficacy and safety of tislelizumab combined with bevacizumab and platinum-based pemetrexed in the treatment of naïve patients with advanced non-squamous non-small cell lung cancer with sensitive EGFR mutations and high PD-L1 expression Prospective, open-label, single-arm phase II clinical study
This is a prospective, multi-center, single-arm clinical trial to evaluate the safety and effectiveness of Almonertinib treatment in patients with EGFR mutation positive and advanced non-small cell lung cancer (NSCLC) who are intolerant to the safety of osimertinib treatment.
This is a phase III clinical trial aimed to compare the efficacy and safety of Osimertinib monotherapy and combination of Osimertinib, pemetrexed and carboplatin in untreated patients with advanced non-small cell lung cancer with concurrent EGFR and TP53 mutation.
