Egf R Positive Non Small Cell Lung Cancer

clinical trial The goal of this clinical trial is to learn whether the treatment of advanced non-small cell lung cancer with EGFR-TKIs, when combined with bevacizumab in the presence of positive circulating tumor cells in the cerebrospinal fluid, has better therapeutic efficacy. The main questions it aims to answer are:1.When EGFR-TKIs are sequentially combined with bevacizumab along with EGFR-TKIs for first-line treatment of advanced non-small cell lung cancer, how long can the participants survive? 2.What medical problems do participants have when using EGFR-TKIs sequentially combined with bevacizumab in conjunction with EGFR-TKIs. Participants will: Receive EGFR-TKIs treatment for a duration of 3 months, and upon a positive cerebrospinal fluid tumor cell status, subsequently receive bevacizumab combined with EGFR-TKIs treatment until disease progression. Visit the clinic for check-ups and tests every two weeks, and have follow-up visits every six weeks after the treatment ends. Keep a record of their symptoms and disease progression.

This is an open-label, single-arm, dose-escalation, multicenter phase I/II clinical trial. The primary endpoints of this study were to evaluated the safety, tolerability, pharmacokinetic profile and preliminary efficacy of HE003 in combination with osimertinib in patients with advanced solid tumors who have failed previous standard therapy. The secondary endpoints of this study were to evaluated the efficacy HE003 in combination with osimertinib in patients with advanced solid tumors who have failed previous standard therapy.

This study aimed to assess the value of dynamic ctDNA monitoring in guiding the development of personalized neoadjuvant treatment strategies for EGFR-mutated NSCLC patients.

Phase II Study to Evaluate the Impact of SBRT (Stereotactic Body Radiation Therapy) and/or SRS (Stereotactic Radiosurgery) on Oligoresidual Disease in EGFR Mutation Patients Treated with Osimertinib as First-Line Systemic Intervention. All candidates must exhibit a partial response after 12 weeks of treatment with the third-generation tyrosine kinase inhibitor (alone or in combination with chemotherapy) and a maximum of five (5) residual lesions in a maximum of two (2) organs. The primary outcome will be progression-free survival (PFS), and secondary outcomes will include overall survival (OS), proportion of patients without progression at months 12 and 36, safety, and overall response rate (ORR). Additionally, an exploratory analysis will be conducted on the prognostic value of liquid biopsy (supplementary information), considering baseline presence of mutations (determined by Next Generation Sequencing tests) and reduction or negativization of allelic fraction (AF).

Icotinib is a first-generation inhibitor of EGFR-tyrosine kinase inhibitor in patients with non-small-cell lung cancer (NSCLC). Here we will evaluate neoadjuvant Icotinib with chemotherapy prior to surgery, in patients with resectable stage II-IIIB N2 EGFR mutation-positive NSCLC. The primary endpoint is centrally assessed major pathological response at the time of resection. Secondary endpoints include pathological complete response, objective response rate, R0 resection rate at the time of resection, disease-free survival, and overall survival. Safety and tolerability will also be assessed.

This study involves patients with EGFR-mutated NSCLC and asymptomatic brain metastases. This is an open-label, randomized study, comparing the continuation of Osimertinib treatment alone to Osimertinib treatment combined with early intervention stereotactic radiosurgery (SRS). The current first line of care for EGFR-mutated NSCLC is administration of Osimertinib, a small molecule that penetrates the blood brain barrier (BBB) well and controls majority, but not all, of the brain metastases. We hypothesize that relatively early intervention with SRS to brain metastases that are still visualized by MRI 2 months-post initiation of Osimertinib treatment, LUNG- will improve long term brain control, cognitive abilities and potentially overall survival. Patients with EGFR-mutated NSCLC and asymptomatic brain metastases will be treated with Osimertinib for 2 months. Brain MRI scans will be collected pre-Osimertinib and 2 months after treatment start. Patients with asymptomatic brain metastases present after 2 months of Osimertinib will be randomized into one of two study arms. Arm A patients will be treated with SRS while continuing Osimertinib, while arm B patients will continue with Osimertinib alone. Patients will be assessed based on brain and whole body progression by RECIST. Patients will also be assessed for CNS-PFS and body-PFS, cognitive function, Quality of life and overall survival status via routine follow-up tests.
