Filter by:REPOSE is a phase II clinical trial exploring the safety and efficacy of repotrectinib in patients with non-small cell lung cancer (NSCLC) characterized by the presence of brain metastasis (BM) and whose tumors have mutated ROS proto-oncogene 1, receptor tyrosine kinase (ROS1) gene.
This study is an investigator-initiated, prospective, open-label, single-arm, multicenter clinical trial aimed at exploring the antitumor activity of Lorlatinib in ALK-positive NSCLC patients with brain/ leptomeningeal metastases.
The purpose of this study is to discover the potential convenience and ease of using a Magnetic Resonance Imaging (MRI) technique, named Magnetic Resonance Fingerprinting (or MRF), to achieve high-quality images within a short scan time of 5 min for viewing the entire brain. This is an advanced quantitative assessment of brain tissues. This method is being applied with IVIM MRI to be able to tell the difference between a brain with radiation necrosis and a brain with tumor recurrence. Participants will consist of individuals who have received radiation therapy in the past and were diagnosed with radiation necrosis, individuals with recurrent tumors, and healthy individuals who have no brain diseases and have not had radiation treatment to the brain. Participants will undergo an MRI scan at a one-time research study visit; no extra tests or procedures will be required for this research study. The primary objectives of this study are: - To demonstrate the clinical feasibility of combining MRF with state-of-the-art parallel imaging techniques to achieve high-resolution quantitative imaging within a reasonable scan time of 5 min for whole brain coverage. - To apply the developed quantitative approach in combination with IVIM MRI for differentiation of tumor recurrence and radiation necrosis.
This research study will evaluate the efficacy and safety of stereotactic radiotherapy (SRT) combined with Trastuzumab-Deruxtecan (T-DXd; DS-8201a) in HER2-positive Breast Cancer Patients with newly diagnosed or progressing Brain Metastases.
The goal of this diagnostic intervention clinical trial is to compare 18F-Fluciclovine uptake within brain lesions over 60 minutes compared with standard of care positive histology confirmation or confirmation MRI images. The main questions it aims to answer are: 1. What are the dynamics of 18F-Fluciclovine update within a non-treated metastatic brain lesion over 60 minutes? 2. What are the dynamics of 18F-fluciclovine update within recently treated metastatic brain lesions? 3. What is the potential use of 18F-Fluciclovine in delineating true local progression from radionecrosis in patients with clinical uncertainty of indeterminate MRI? Participants will undergo an 18F-fluciclovine head PET/CT scan prior to treatment for brain metastatic lesion(s). The study will characterize uptake dynamic PET images over 60 minutes. Uptake within the lesions and the benign brain parenchyma will be plotted on a time activity curve for 60 mins. Patients will undergo a second 18F-fluciclovine PET/CT to evaluate 18F-fluciclovine uptake in treated lesions over 60 minutes. This will be offered concurrently with the post-procedure standard of care (SOC) MRI to evaluate post-treatment changes. Uptake within the lesions and the benign brain parenchyma will be plotted on a 60 min time activity curve. Results will be compared to the pre-treatment baseline images. A third 18F-fluciclovine PET/CT will be offered to evaluate post radiation changes necrosis from recurrence, for up to 10 patients in our cohort who are under clinical surveillance (up to three years surveillance) and developed MRI evidence of either true progression or radionecrosis with clinical uncertainty after stereotactic radiosurgery. The initial 18F-fluciclovine PET/CT will serve as a baseline PET/CT scan. This will be compared to post procedural histological confirmation.
To learn if 18F-Fluciclovine (Axumin) PET-CT scans can be used to better detect brain metastatic lesions in patients who are receiving immunotherapy.
Patients suffering from malignancies in advanced stages often develop brain metastases, which limit both the life span and the quality of life. Combining surgery and radiotherapy for resectable brain metastases is standard of care but there is a lot of controversy on which kind of radiotherapy is best suitable. Recently, first volumetric in-silico analyses point to theoretical advantages of neoadjuvant stereotactic radiotherapy of brain metastases. Special about this trial is the direct comparison between the three currently discussed radiotherapy options for resectable brain metastases: Neoadjuvant stereotactic radiotherapy, intraoperative radiotherapy and adjuvant stereotactic radiotherapy.
This trial uses multi-parametric magnetic resonance imaging (MRI) to develop and validate imaging risk score to predict radiation necrosis in participants with brain metastasis treated with radiation therapy. Diagnostic procedures, such as multi-parametric magnetic resonance imaging (MRI), may improve the ability to diagnose radiation necrosis early and help establish treatment strategies.
The purpose of this study was to investigate the efficacy and safety of Cadonilimab combined with bevacizumab and chemotherapy for advanced non-squamous NSCLC with untreated brain metastases. Cadonilimab is a bispecific antibody (BsAb), which can bind PD-1 and CTLA-4 at the same time with high affinity. It is a new tumor immunotherapy drug with tetravalent structure and short half-life. It has shown less toxicity than anti-PD-1 and anti-CTLA-4 antibodies in monkey toxicity studies. These characteristics make the application of Cadonilimab in tumor subjects may have better efficacy and safety. AK104-207 is an open, multicenter, phase Ib/II clinical study, which aims to evaluate the effectiveness and safety of Cadonilimab combined with chemotherapy as the first-line treatment for locally advanced or metastatic non-small cell lung cancer that cannot be operated and cannot receive radical concurrent/sequential radiotherapy and chemotherapy. As of August 1, 2022, 19 subjects who can evaluate non-squamous NSCLC (cohort B), ORR is 63.2%, DCR is 100%, median PFS is 13.34 months (7.36, NE), median OS is not reached, and 12-month OS rate is 76.0% (95% CI 48.0-90.3). In PD-L1 positive patients (n=9), ORR was 55.6% and DCR was 100%. In PD-L1 negative patients (n=7), ORR was 85.7% and DCR was 100%. In view of the early curative effect of Cadonilimab in NSCLC single drug or combination therapy and the encouraging research results of PD-1 inhibitor combined with CTLA-4 double immune combination therapy, it is expected that Cadonilimab combined with bevacizumab and chemotherapy will achieve good curative effect in NSCLC patients with brain metastasis.
