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.
Phase II, single-arm, open-label study that assess clinical feasibility and safety of neoadjuvant almonertinib followed by 3 cycles neoadjuvant adebrelimab plus chemotherapy in EGFR-mutant stage IIA-IIIB NSCLC followed by surgery, adjuvant treatment was upon investigators' decisions.
The goal of this clinical interventional study is to compare the efficacy of mobile healthcare education in two ways (game-based or text-based) to improve cutaneous self-care capability in cancer patients receiving EGFR-based target therapy. The main questions it aims to answer are: Impact of different mobile healthcare education ways on cutaneous self-care capability of patients Impact of different mobile healthcare education ways on learning motivation of patients towards cutaneous self-care knowledge and skills Participants will be randomly divided into two groups. Both groups will download a healthcare education application on their phone. One group will accept the education about the knowledge and self-care skills of cutaneous adverse drug reaction by playing game. In contrast, the other group will accept the same education content by reading text on the phone. Subjects will be asked to use the application at home for two weeks after giving consent to participate this study, and then completed questionnaire three times during study period. The timepoints of completing questionnaire are listed following: Baseline / pre-intervention test (after signing informed consent form, D1) First post-intervention test (after finishing intervention, D15) Second post-intervention test (D30) Researchers will compare game group and text group to see if game group has better performance on cutaneous self-care capability and learning motivation.
The goal of this interventional phase III clinical trial is to evaluate objective intracranial response rate (iORR) after a treatment with total cranial radiation therapy plus concomitant transdermal nitroglycerin (NTG) addition or total cranial radiation therapy only in patients with stage IV non-small cell lung cancer with brain metastases and EGFR mutation. The main questions it aims to answer are: Determine progression-free survival (PFS) to CNS and overall survival (OS). Evaluate and compare the quality of life (QoL) of patients during and after treatment. Evaluate the cognitive function of patients before, during and after treatment. Evaluate treatment-associated toxicity to grade adverse treatment events Evaluation of HIF1α, VEGF and ROS1 in peripheral blood before and after nitroglycerin treatment. All participants will have laboratory tests at the beginning and end of radiation therapy. Cranial MRI will be performed prior to treatment and 12 weeks after the end of treatment, then every 16 weeks until intracranial progression. Patients in the interventional group will be given 36 mg patches of transdermal nitroglycerin for 24 hours with a 12-hour rest interval during treatment with radiation therapy. The control group will only receive total cranial radiation therapy at the same doses and with the same schedule.
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 phase I trial tests the safety, side effects, and best dose of E-SYNC chimeric antigen receptor (CAR) T cells after lymphodepleting chemotherapy in treating patients with EGFRvIII positive (+) glioblastoma. Chimeric antigen receptor (CAR) T-cell therapy is a type of treatment in which a patient's T cells (a type of immune system cell) are changed in the laboratory so the CAR T cells will attack cancer cells. T cells are taken from a patient's blood. Then the gene for a special receptor that binds to a certain protein on the patient's cancer cells is added to the T cells in the laboratory. The special receptor is called a chimeric antigen receptor. Large numbers of the CAR T cells are grown in the laboratory and given to the patient by infusion for treatment of certain cancers. Lymphodepleting chemotherapy with cyclophosphamide and fludarabine before treatment with CAR T cells may make the CAR T cells more effective.
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.
To evaluate the efficacy (ORR) and safety of anti PD-1 monoclonal antibody combined with neoantigen peptide vaccine and chemotherapy in the treatment of advanced NSCLC progressed after EGFR-TKI treatment and to provide new treatment methods for EGFR-TKI resistant patients.
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
